-  <title>DRM Core</title>
-  <partintro>
-    <para>
-      This first part of the GPU Driver Developer's Guide documents core DRM
-      code, helper libraries for writing drivers and generic userspace
-      interfaces exposed by DRM drivers.

-    <title>Introduction</title>
-    <para>
-      The Linux DRM layer contains code intended to support the needs
-      of complex graphics devices, usually containing programmable
-      pipelines well suited to 3D graphics acceleration.  Graphics
-      drivers in the kernel may make use of DRM functions to make
-      tasks like memory management, interrupt handling and DMA easier,
-      and provide a uniform interface to applications.
-    </para>
-    <para>
-      A note on versions: this guide covers features found in the DRM
-      tree, including the TTM memory manager, output configuration and
-      mode setting, and the new vblank internals, in addition to all
-      the regular features found in current kernels.
-    </para>

-    <title>Style Guidelines</title>
-    <para>
-      For consistency this documentation uses American English. Abbreviations
-      are written as all-uppercase, for example: DRM, KMS, IOCTL, CRTC, and so
-      on. To aid in reading, documentations make full use of the markup
-      characters kerneldoc provides: @parameter for function parameters, @member
-      for structure members, &amp;structure to reference structures and
-      function() for functions. These all get automatically hyperlinked if
-      kerneldoc for the referenced objects exists. When referencing entries in
-      function vtables please use -&gt;vfunc(). Note that kerneldoc does
-      not support referencing struct members directly, so please add a reference
-      to the vtable struct somewhere in the same paragraph or at least section.
-    </para>
-    <para>
-      Except in special situations (to separate locked from unlocked variants)
-      locking requirements for functions aren't documented in the kerneldoc.
-      Instead locking should be check at runtime using e.g.
-      <code>WARN_ON(!mutex_is_locked(...));</code>. Since it's much easier to
-      ignore documentation than runtime noise this provides more value. And on
-      top of that runtime checks do need to be updated when the locking rules
-      change, increasing the chances that they're correct. Within the
-      documentation the locking rules should be explained in the relevant
-      structures: Either in the comment for the lock explaining what it
-      protects, or data fields need a note about which lock protects them, or
-      both.
-    </para>
-    <para>
-      Functions which have a non-<code>void</code> return value should have a
-      section called "Returns" explaining the expected return values in
-      different cases and their meanings. Currently there's no consensus whether
-      that section name should be all upper-case or not, and whether it should
-      end in a colon or not. Go with the file-local style. Other common section
-      names are "Notes" with information for dangerous or tricky corner cases,
-      and "FIXME" where the interface could be cleaned up.

-  <chapter id="drmInternals">
-    <title>DRM Internals</title>
-    <para>
-      This chapter documents DRM internals relevant to driver authors
-      and developers working to add support for the latest features to
-      existing drivers.
-    </para>
-    <para>
-      First, we go over some typical driver initialization
-      requirements, like setting up command buffers, creating an
-      initial output configuration, and initializing core services.
-      Subsequent sections cover core internals in more detail,
-      providing implementation notes and examples.
-    </para>
-    <para>
-      The DRM layer provides several services to graphics drivers,
-      many of them driven by the application interfaces it provides
-      through libdrm, the library that wraps most of the DRM ioctls.
-      These include vblank event handling, memory
-      management, output management, framebuffer management, command
-      submission &amp; fencing, suspend/resume support, and DMA
-      services.
-    </para>

-  <!-- Internals: driver init -->
-
-  <sect1>
-    <title>Driver Initialization</title>
-    <para>
-      At the core of every DRM driver is a <structname>drm_driver</structname>
-      structure. Drivers typically statically initialize a drm_driver structure,
-      and then pass it to <function>drm_dev_alloc()</function> to allocate a
-      device instance. After the device instance is fully initialized it can be
-      registered (which makes it accessible from userspace) using
-      <function>drm_dev_register()</function>.
-    </para>
-    <para>
-      The <structname>drm_driver</structname> structure contains static
-      information that describes the driver and features it supports, and
-      pointers to methods that the DRM core will call to implement the DRM API.
-      We will first go through the <structname>drm_driver</structname> static
-      information fields, and will then describe individual operations in
-      details as they get used in later sections.
-    </para>
-    <sect2>
-      <title>Driver Information</title>
-      <sect3>
-        <title>Driver Features</title>
-        <para>
-          Drivers inform the DRM core about their requirements and supported
-          features by setting appropriate flags in the
-          <structfield>driver_features</structfield> field. Since those flags
-          influence the DRM core behaviour since registration time, most of them
-          must be set to registering the <structname>drm_driver</structname>
-          instance.

-        <synopsis>int major;

-int patchlevel;</synopsis>
-        <para>
-          The DRM core identifies driver versions by a major, minor and patch
-          level triplet. The information is printed to the kernel log at
-          initialization time and passed to userspace through the
-          DRM_IOCTL_VERSION ioctl.
-        </para>
-        <para>
-          The major and minor numbers are also used to verify the requested driver
-          API version passed to DRM_IOCTL_SET_VERSION. When the driver API changes
-          between minor versions, applications can call DRM_IOCTL_SET_VERSION to
-          select a specific version of the API. If the requested major isn't equal
-          to the driver major, or the requested minor is larger than the driver
-          minor, the DRM_IOCTL_SET_VERSION call will return an error. Otherwise
-          the driver's set_version() method will be called with the requested
-          version.

-        <para>
-          The driver name is printed to the kernel log at initialization time,
-          used for IRQ registration and passed to userspace through
-          DRM_IOCTL_VERSION.
-        </para>
-        <para>
-          The driver description is a purely informative string passed to
-          userspace through the DRM_IOCTL_VERSION ioctl and otherwise unused by
-          the kernel.
-        </para>
-        <para>
-          The driver date, formatted as YYYYMMDD, is meant to identify the date of
-          the latest modification to the driver. However, as most drivers fail to
-          update it, its value is mostly useless. The DRM core prints it to the
-          kernel log at initialization time and passes it to userspace through the
-          DRM_IOCTL_VERSION ioctl.

-        <title>IRQ Registration</title>
-        <para>
-          The DRM core tries to facilitate IRQ handler registration and
-          unregistration by providing <function>drm_irq_install</function> and
-          <function>drm_irq_uninstall</function> functions. Those functions only
-          support a single interrupt per device, devices that use more than one
-          IRQs need to be handled manually.
-        </para>
-        <sect4>
-          <title>Managed IRQ Registration</title>
-          <para>
-            <function>drm_irq_install</function> starts by calling the
-            <methodname>irq_preinstall</methodname> driver operation. The operation
-            is optional and must make sure that the interrupt will not get fired by
-            clearing all pending interrupt flags or disabling the interrupt.
-          </para>
-          <para>
-            The passed-in IRQ will then be requested by a call to
-            <function>request_irq</function>. If the DRIVER_IRQ_SHARED driver
-            feature flag is set, a shared (IRQF_SHARED) IRQ handler will be
-            requested.
-          </para>
-          <para>
-            The IRQ handler function must be provided as the mandatory irq_handler
-            driver operation. It will get passed directly to
-            <function>request_irq</function> and thus has the same prototype as all
-            IRQ handlers. It will get called with a pointer to the DRM device as the
-            second argument.
-          </para>
-          <para>
-            Finally the function calls the optional
-            <methodname>irq_postinstall</methodname> driver operation. The operation
-            usually enables interrupts (excluding the vblank interrupt, which is
-            enabled separately), but drivers may choose to enable/disable interrupts
-            at a different time.
-          </para>
-          <para>
-            <function>drm_irq_uninstall</function> is similarly used to uninstall an
-            IRQ handler. It starts by waking up all processes waiting on a vblank
-            interrupt to make sure they don't hang, and then calls the optional
-            <methodname>irq_uninstall</methodname> driver operation. The operation
-            must disable all hardware interrupts. Finally the function frees the IRQ
-            by calling <function>free_irq</function>.

-          <title>Manual IRQ Registration</title>
-          <para>
-            Drivers that require multiple interrupt handlers can't use the managed
-            IRQ registration functions. In that case IRQs must be registered and
-            unregistered manually (usually with the <function>request_irq</function>
-            and <function>free_irq</function> functions, or their devm_* equivalent).
-          </para>
-          <para>
-            When manually registering IRQs, drivers must not set the DRIVER_HAVE_IRQ
-            driver feature flag, and must not provide the
-	    <methodname>irq_handler</methodname> driver operation. They must set the
-	    <structname>drm_device</structname> <structfield>irq_enabled</structfield>
-	    field to 1 upon registration of the IRQs, and clear it to 0 after
-	    unregistering the IRQs.

-        <title>Memory Manager Initialization</title>
-        <para>
-          Every DRM driver requires a memory manager which must be initialized at
-          load time. DRM currently contains two memory managers, the Translation
-          Table Manager (TTM) and the Graphics Execution Manager (GEM).
-          This document describes the use of the GEM memory manager only. See
-          <xref linkend="drm-memory-management"/> for details.

-        <title>Miscellaneous Device Configuration</title>
-        <para>
-          Another task that may be necessary for PCI devices during configuration
-          is mapping the video BIOS. On many devices, the VBIOS describes device
-          configuration, LCD panel timings (if any), and contains flags indicating
-          device state. Mapping the BIOS can be done using the pci_map_rom() call,
-          a convenience function that takes care of mapping the actual ROM,
-          whether it has been shadowed into memory (typically at address 0xc0000)
-          or exists on the PCI device in the ROM BAR. Note that after the ROM has
-          been mapped and any necessary information has been extracted, it should
-          be unmapped; on many devices, the ROM address decoder is shared with
-          other BARs, so leaving it mapped could cause undesired behaviour like
-          hangs or memory corruption.

-      <title>Bus-specific Device Registration and PCI Support</title>
-      <para>
-        A number of functions are provided to help with device registration.
-	The functions deal with PCI and platform devices respectively and are
-	only provided for historical reasons. These are all deprecated and
-	shouldn't be used in new drivers. Besides that there's a few
-	helpers for pci drivers.

-    <title>Memory management</title>
-    <para>
-      Modern Linux systems require large amount of graphics memory to store
-      frame buffers, textures, vertices and other graphics-related data. Given
-      the very dynamic nature of many of that data, managing graphics memory
-      efficiently is thus crucial for the graphics stack and plays a central
-      role in the DRM infrastructure.
-    </para>
-    <para>
-      The DRM core includes two memory managers, namely Translation Table Maps
-      (TTM) and Graphics Execution Manager (GEM). TTM was the first DRM memory
-      manager to be developed and tried to be a one-size-fits-them all
-      solution. It provides a single userspace API to accommodate the need of
-      all hardware, supporting both Unified Memory Architecture (UMA) devices
-      and devices with dedicated video RAM (i.e. most discrete video cards).
-      This resulted in a large, complex piece of code that turned out to be
-      hard to use for driver development.
-    </para>
-    <para>
-      GEM started as an Intel-sponsored project in reaction to TTM's
-      complexity. Its design philosophy is completely different: instead of
-      providing a solution to every graphics memory-related problems, GEM
-      identified common code between drivers and created a support library to
-      share it. GEM has simpler initialization and execution requirements than
-      TTM, but has no video RAM management capabilities and is thus limited to
-      UMA devices.

-          Drivers wishing to support TTM must fill out a drm_bo_driver
-          structure. The structure contains several fields with function
-          pointers for initializing the TTM, allocating and freeing memory,
-          waiting for command completion and fence synchronization, and memory
-          migration. See the radeon_ttm.c file for an example of usage.

-          The ttm_global_reference structure is made up of several fields:

-          struct ttm_global_reference {

-        <para>
-          There should be one global reference structure for your memory
-          manager as a whole, and there will be others for each object
-          created by the memory manager at runtime.  Your global TTM should
-          have a type of TTM_GLOBAL_TTM_MEM.  The size field for the global
-          object should be sizeof(struct ttm_mem_global), and the init and
-          release hooks should point at your driver-specific init and
-          release routines, which probably eventually call
-          ttm_mem_global_init and ttm_mem_global_release, respectively.
-        </para>
-        <para>
-          Once your global TTM accounting structure is set up and initialized
-          by calling ttm_global_item_ref() on it,
-          you need to create a buffer object TTM to
-          provide a pool for buffer object allocation by clients and the
-          kernel itself.  The type of this object should be TTM_GLOBAL_TTM_BO,
-          and its size should be sizeof(struct ttm_bo_global).  Again,
-          driver-specific init and release functions may be provided,
-          likely eventually calling ttm_bo_global_init() and
-          ttm_bo_global_release(), respectively.  Also, like the previous
-          object, ttm_global_item_ref() is used to create an initial reference
-          count for the TTM, which will call your initialization function.

-      <title>The Graphics Execution Manager (GEM)</title>
-      <para>
-        The GEM design approach has resulted in a memory manager that doesn't
-        provide full coverage of all (or even all common) use cases in its
-        userspace or kernel API. GEM exposes a set of standard memory-related
-        operations to userspace and a set of helper functions to drivers, and let
-        drivers implement hardware-specific operations with their own private API.
-      </para>
-      <para>
-        The GEM userspace API is described in the

-        outdated, the document provides a good overview of the GEM API principles.
-        Buffer allocation and read and write operations, described as part of the
-        common GEM API, are currently implemented using driver-specific ioctls.
-      </para>
-      <para>
-        GEM is data-agnostic. It manages abstract buffer objects without knowing
-        what individual buffers contain. APIs that require knowledge of buffer
-        contents or purpose, such as buffer allocation or synchronization
-        primitives, are thus outside of the scope of GEM and must be implemented
-        using driver-specific ioctls.
-      </para>

-          In a KMS configuration, drivers need to allocate and initialize a

-          memory region, which provides space for the initial framebuffer and
-          large, contiguous memory regions required by the device. This space is
-          typically not managed by GEM, and must be initialized separately into

-        <para>
-          GEM objects are represented by an instance of struct
-          <structname>drm_gem_object</structname>. Drivers usually need to extend
-          GEM objects with private information and thus create a driver-specific
-          GEM object structure type that embeds an instance of struct
-          <structname>drm_gem_object</structname>.
-        </para>
-        <para>
-          To create a GEM object, a driver allocates memory for an instance of its
-          specific GEM object type and initializes the embedded struct
-          <structname>drm_gem_object</structname> with a call to
-          <function>drm_gem_object_init</function>. The function takes a pointer to
-          the DRM device, a pointer to the GEM object and the buffer object size
-          in bytes.

-          GEM uses shmem to allocate anonymous pageable memory.
-          <function>drm_gem_object_init</function> will create an shmfs file of

-          <structname>drm_gem_object</structname> <structfield>filp</structfield>
-          field. The memory is used as either main storage for the object when the

-          Note that they can decide to allocate pages when initializing the GEM
-          object, or to delay allocation until the memory is needed (for instance
-          when a page fault occurs as a result of a userspace memory access or
-          when the driver needs to start a DMA transfer involving the memory).

-          Anonymous pageable memory allocation is not always desired, for instance
-          when the hardware requires physically contiguous system memory as is
-          often the case in embedded devices. Drivers can create GEM objects with
-          no shmfs backing (called private GEM objects) by initializing them with
-          a call to <function>drm_gem_private_object_init</function> instead of
-          <function>drm_gem_object_init</function>. Storage for private GEM
-          objects must be managed by drivers.

-          Communication between userspace and the kernel refers to GEM objects
-          using local handles, global names or, more recently, file descriptors.
-          All of those are 32-bit integer values; the usual Linux kernel limits
-          apply to the file descriptors.
-        </para>
-        <para>
-          GEM handles are local to a DRM file. Applications get a handle to a GEM
-          object through a driver-specific ioctl, and can use that handle to refer
-          to the GEM object in other standard or driver-specific ioctls. Closing a
-          DRM file handle frees all its GEM handles and dereferences the
-          associated GEM objects.
-        </para>
-        <para>
-          To create a handle for a GEM object drivers call
-          <function>drm_gem_handle_create</function>. The function takes a pointer
-          to the DRM file and the GEM object and returns a locally unique handle.
-          When the handle is no longer needed drivers delete it with a call to
-          <function>drm_gem_handle_delete</function>. Finally the GEM object
-          associated with a handle can be retrieved by a call to
-          <function>drm_gem_object_lookup</function>.
-        </para>
-        <para>
-          Handles don't take ownership of GEM objects, they only take a reference
-          to the object that will be dropped when the handle is destroyed. To
-          avoid leaking GEM objects, drivers must make sure they drop the
-          reference(s) they own (such as the initial reference taken at object
-          creation time) as appropriate, without any special consideration for the
-          handle. For example, in the particular case of combined GEM object and
-          handle creation in the implementation of the
-          <methodname>dumb_create</methodname> operation, drivers must drop the
-          initial reference to the GEM object before returning the handle.
-        </para>
-        <para>
-          GEM names are similar in purpose to handles but are not local to DRM
-          files. They can be passed between processes to reference a GEM object
-          globally. Names can't be used directly to refer to objects in the DRM
-          API, applications must convert handles to names and names to handles
-          using the DRM_IOCTL_GEM_FLINK and DRM_IOCTL_GEM_OPEN ioctls
-          respectively. The conversion is handled by the DRM core without any
-          driver-specific support.
-        </para>
-        <para>
-          GEM also supports buffer sharing with dma-buf file descriptors through
-          PRIME. GEM-based drivers must use the provided helpers functions to
-          implement the exporting and importing correctly. See <xref linkend="drm-prime-support" />.
-          Since sharing file descriptors is inherently more secure than the
-          easily guessable and global GEM names it is the preferred buffer
-          sharing mechanism. Sharing buffers through GEM names is only supported
-          for legacy userspace. Furthermore PRIME also allows cross-device
-          buffer sharing since it is based on dma-bufs.

-          Because mapping operations are fairly heavyweight GEM favours

-          The mmap system call can't be used directly to map GEM objects, as they
-          don't have their own file handle. Two alternative methods currently
-          co-exist to map GEM objects to userspace. The first method uses a
-          driver-specific ioctl to perform the mapping operation, calling
-          <function>do_mmap</function> under the hood. This is often considered

-          DRM identifies the GEM object to be mapped by a fake offset passed
-          through the mmap offset argument. Prior to being mapped, a GEM object
-          must thus be associated with a fake offset. To do so, drivers must call

-        <para>
-          Once allocated, the fake offset value

-        <para>
-          The GEM core provides a helper method <function>drm_gem_mmap</function>
-          to handle object mapping. The method can be set directly as the mmap

-        <para>
-          When mapped to the device or used in a command buffer, backing pages
-          for an object are flushed to memory and marked write combined so as to
-          be coherent with the GPU. Likewise, if the CPU accesses an object
-          after the GPU has finished rendering to the object, then the object
-          must be made coherent with the CPU's view of memory, usually involving
-          GPU cache flushing of various kinds. This core CPU&lt;-&gt;GPU
-          coherency management is provided by a device-specific ioctl, which
-          evaluates an object's current domain and performs any necessary
-          flushing or synchronization to put the object into the desired
-          coherency domain (note that the object may be busy, i.e. an active
-          render target; in that case, setting the domain blocks the client and
-          waits for rendering to complete before performing any necessary
-          flushing operations).

-        <title>Command Execution</title>
-        <para>
-          Perhaps the most important GEM function for GPU devices is providing a
-          command execution interface to clients. Client programs construct
-          command buffers containing references to previously allocated memory
-          objects, and then submit them to GEM. At that point, GEM takes care to
-          bind all the objects into the GTT, execute the buffer, and provide
-          necessary synchronization between clients accessing the same buffers.
-          This often involves evicting some objects from the GTT and re-binding
-          others (a fairly expensive operation), and providing relocation
-          support which hides fixed GTT offsets from clients. Clients must take
-          care not to submit command buffers that reference more objects than
-          can fit in the GTT; otherwise, GEM will reject them and no rendering
-          will occur. Similarly, if several objects in the buffer require fence
-          registers to be allocated for correct rendering (e.g. 2D blits on
-          pre-965 chips), care must be taken not to require more fence registers
-          than are available to the client. Such resource management should be
-          abstracted from the client in libdrm.

-      <para>
-        PRIME is the cross device buffer sharing framework in drm, originally
-        created for the OPTIMUS range of multi-gpu platforms. To userspace
-        PRIME buffers are dma-buf based file descriptors.

-        <para>
-          Similar to GEM global names, PRIME file descriptors are
-          also used to share buffer objects across processes. They offer
-          additional security: as file descriptors must be explicitly sent over
-          UNIX domain sockets to be shared between applications, they can't be
-          guessed like the globally unique GEM names.

-          Drivers that support the PRIME

-      <title>Frame Buffer Abstraction</title>
-      <para>
-        Frame buffers are abstract memory objects that provide a source of
-        pixels to scanout to a CRTC. Applications explicitly request the
-        creation of frame buffers through the DRM_IOCTL_MODE_ADDFB(2) ioctls and
-        receive an opaque handle that can be passed to the KMS CRTC control,
-        plane configuration and page flip functions.
-      </para>
-      <para>
-        Frame buffers rely on the underneath memory manager for low-level memory
-        operations. When creating a frame buffer applications pass a memory
-        handle (or a list of memory handles for multi-planar formats) through
-	the <parameter>drm_mode_fb_cmd2</parameter> argument. For drivers using
-	GEM as their userspace buffer management interface this would be a GEM
-	handle.  Drivers are however free to use their own backing storage object
-	handles, e.g. vmwgfx directly exposes special TTM handles to userspace
-	and so expects TTM handles in the create ioctl and not GEM handles.
-      </para>
-      <para>
-	The lifetime of a drm framebuffer is controlled with a reference count,
-	drivers can grab additional references with
-	<function>drm_framebuffer_reference</function>and drop them
-	again with <function>drm_framebuffer_unreference</function>. For
-	driver-private framebuffers for which the last reference is never
-	dropped (e.g. for the fbdev framebuffer when the struct
-	<structname>drm_framebuffer</structname> is embedded into the fbdev
-	helper struct) drivers can manually clean up a framebuffer at module
-	unload time with
-	<function>drm_framebuffer_unregister_private</function>.

-      <title>Dumb Buffer Objects</title>
-      <para>
-	The KMS API doesn't standardize backing storage object creation and
-	leaves it to driver-specific ioctls. Furthermore actually creating a
-	buffer object even for GEM-based drivers is done through a
-	driver-specific ioctl - GEM only has a common userspace interface for
-	sharing and destroying objects. While not an issue for full-fledged
-	graphics stacks that include device-specific userspace components (in
-	libdrm for instance), this limit makes DRM-based early boot graphics
-	unnecessarily complex.
-      </para>
-      <para>
-        Dumb objects partly alleviate the problem by providing a standard

-    <title>Mode Setting Helper Functions</title>
-    <para>
-      The plane, CRTC, encoder and connector functions provided by the drivers
-      implement the DRM API. They're called by the DRM core and ioctl handlers
-      to handle device state changes and configuration request. As implementing
-      those functions often requires logic not specific to drivers, mid-layer
-      helper functions are available to avoid duplicating boilerplate code.
-    </para>
-    <para>
-      The DRM core contains one mid-layer implementation. The mid-layer provides
-      implementations of several plane, CRTC, encoder and connector functions
-      (called from the top of the mid-layer) that pre-process requests and call
-      lower-level functions provided by the driver (at the bottom of the
-      mid-layer). For instance, the
-      <function>drm_crtc_helper_set_config</function> function can be used to
-      fill the struct <structname>drm_crtc_funcs</structname>
-      <structfield>set_config</structfield> field. When called, it will split
-      the <methodname>set_config</methodname> operation in smaller, simpler
-      operations and call the driver to handle them.
-    </para>
-    <para>
-      To use the mid-layer, drivers call <function>drm_crtc_helper_add</function>,
-      <function>drm_encoder_helper_add</function> and
-      <function>drm_connector_helper_add</function> functions to install their
-      mid-layer bottom operations handlers, and fill the
-      <structname>drm_crtc_funcs</structname>,
-      <structname>drm_encoder_funcs</structname> and
-      <structname>drm_connector_funcs</structname> structures with pointers to
-      the mid-layer top API functions. Installing the mid-layer bottom operation
-      handlers is best done right after registering the corresponding KMS object.
-    </para>
-    <para>
-      The mid-layer is not split between CRTC, encoder and connector operations.
-      To use it, a driver must provide bottom functions for all of the three KMS
-      entities.

-    <title>Vertical Blanking</title>
-    <para>
-      Vertical blanking plays a major role in graphics rendering. To achieve
-      tear-free display, users must synchronize page flips and/or rendering to
-      vertical blanking. The DRM API offers ioctls to perform page flips
-      synchronized to vertical blanking and wait for vertical blanking.
-    </para>
-    <para>
-      The DRM core handles most of the vertical blanking management logic, which
-      involves filtering out spurious interrupts, keeping race-free blanking
-      counters, coping with counter wrap-around and resets and keeping use
-      counts. It relies on the driver to generate vertical blanking interrupts
-      and optionally provide a hardware vertical blanking counter. Drivers must
-      implement the following operations.
-    </para>
-    <itemizedlist>
-      <listitem>
-        <synopsis>int (*enable_vblank) (struct drm_device *dev, int crtc);
-void (*disable_vblank) (struct drm_device *dev, int crtc);</synopsis>
-        <para>
-	  Enable or disable vertical blanking interrupts for the given CRTC.
-	</para>
-      </listitem>
-      <listitem>
-        <synopsis>u32 (*get_vblank_counter) (struct drm_device *dev, int crtc);</synopsis>
-        <para>
-	  Retrieve the value of the vertical blanking counter for the given
-	  CRTC. If the hardware maintains a vertical blanking counter its value
-	  should be returned. Otherwise drivers can use the
-	  <function>drm_vblank_count</function> helper function to handle this
-	  operation.
-	</para>
-      </listitem>
-    </itemizedlist>
-    <para>
-      Drivers must initialize the vertical blanking handling core with a call to
-      <function>drm_vblank_init</function> in their
-      <methodname>load</methodname> operation. The function will set the struct
-      <structname>drm_device</structname>
-      <structfield>vblank_disable_allowed</structfield> field to 0. This will
-      keep vertical blanking interrupts enabled permanently until the first mode
-      set operation, where <structfield>vblank_disable_allowed</structfield> is
-      set to 1. The reason behind this is not clear. Drivers can set the field
-      to 1 after <function>calling drm_vblank_init</function> to make vertical
-      blanking interrupts dynamically managed from the beginning.
-    </para>
-    <para>
-      Vertical blanking interrupts can be enabled by the DRM core or by drivers
-      themselves (for instance to handle page flipping operations). The DRM core
-      maintains a vertical blanking use count to ensure that the interrupts are
-      not disabled while a user still needs them. To increment the use count,
-      drivers call <function>drm_vblank_get</function>. Upon return vertical
-      blanking interrupts are guaranteed to be enabled.
-    </para>
-    <para>
-      To decrement the use count drivers call

-      module parameter or the <varname>drm_vblank_offdelay</varname> global

-        The <methodname>firstopen</methodname> method is called by the DRM core
-	for legacy UMS (User Mode Setting) drivers only when an application
-	opens a device that has no other opened file handle. UMS drivers can

-	method and must acquire resources in the <methodname>load</methodname>
-	method instead.
-      </para>
-      <para>
-	Similarly the <methodname>lastclose</methodname> method is called when
-	the last application holding a file handle opened on the device closes
-	it, for both UMS and KMS drivers. Additionally, the method is also
-	called at module unload time or, for hot-pluggable devices, when the
-	device is unplugged. The <methodname>firstopen</methodname> and
-	<methodname>lastclose</methodname> calls can thus be unbalanced.
-      </para>
-      <para>
-        The <methodname>open</methodname> method is called every time the device
-	is opened by an application. Drivers can allocate per-file private data
-	in this method and store them in the struct
-	<structname>drm_file</structname> <structfield>driver_priv</structfield>

-      <para>
-        The close operation is split into <methodname>preclose</methodname> and

-	cleanup all per-file operations in the <methodname>preclose</methodname>
-	method. For instance pending vertical blanking and page flip events must

-	returning from the <methodname>preclose</methodname> method.
-      </para>
-      <para>
-        Finally the <methodname>postclose</methodname> method is called as the

-	<methodname>lastclose</methodname> method if no other open file handle
-	exists for the device. Drivers that have allocated per-file private data
-	in the <methodname>open</methodname> method should free it here.
-      </para>
-      <para>
-        The <methodname>lastclose</methodname> method should restore CRTC and
-	plane properties to default value, so that a subsequent open of the
-	device will not inherit state from the previous user. It can also be
-	used to execute delayed power switching state changes, e.g. in
-	conjunction with the vga_switcheroo infrastructure (see
-	<xref linkend="vga_switcheroo"/>). Beyond that KMS drivers should not
-	do any further cleanup. Only legacy UMS drivers might need to clean up

-<!-- TODO
-
-- Add a glossary
-- Document the struct_mutex catch-all lock
-- Document connector properties
-
-- Why is the load method optional?
-- What are drivers supposed to set the initial display state to, and how?
-  Connector's DPMS states are not initialized and are thus equal to
-  DRM_MODE_DPMS_ON. The fbcon compatibility layer calls
-  drm_helper_disable_unused_functions(), which disables unused encoders and
-  CRTCs, but doesn't touch the connectors' DPMS state, and
-  drm_helper_connector_dpms() in reaction to fbdev blanking events. Do drivers
-  that don't implement (or just don't use) fbcon compatibility need to call
-  those functions themselves?
-- KMS drivers must call drm_vblank_pre_modeset() and drm_vblank_post_modeset()
-  around mode setting. Should this be done in the DRM core?
-- vblank_disable_allowed is set to 1 in the first drm_vblank_post_modeset()
-  call and never set back to 0. It seems to be safe to permanently set it to 1
-  in drm_vblank_init() for KMS driver, and it might be safe for UMS drivers as
-  well. This should be investigated.
-- crtc and connector .save and .restore operations are only used internally in
-  drivers, should they be removed from the core?
-- encoder mid-layer .save and .restore operations are only used internally in
-  drivers, should they be removed from the core?
-- encoder mid-layer .detect operation is only used internally in drivers,

-    <sect1>
-      <title>Render nodes</title>
-      <para>
-        DRM core provides multiple character-devices for user-space to use.
-        Depending on which device is opened, user-space can perform a different
-        set of operations (mainly ioctls). The primary node is always created
-        and called card&lt;num&gt;. Additionally, a currently
-        unused control node, called controlD&lt;num&gt; is also
-        created. The primary node provides all legacy operations and
-        historically was the only interface used by userspace. With KMS, the
-        control node was introduced. However, the planned KMS control interface
-        has never been written and so the control node stays unused to date.
-      </para>
-      <para>
-        With the increased use of offscreen renderers and GPGPU applications,
-        clients no longer require running compositors or graphics servers to
-        make use of a GPU. But the DRM API required unprivileged clients to
-        authenticate to a DRM-Master prior to getting GPU access. To avoid this
-        step and to grant clients GPU access without authenticating, render
-        nodes were introduced. Render nodes solely serve render clients, that
-        is, no modesetting or privileged ioctls can be issued on render nodes.
-        Only non-global rendering commands are allowed. If a driver supports
-        render nodes, it must advertise it via the DRIVER_RENDER
-        DRM driver capability. If not supported, the primary node must be used
-        for render clients together with the legacy drmAuth authentication
-        procedure.
-      </para>
-      <para>
-        If a driver advertises render node support, DRM core will create a
-        separate render node called renderD&lt;num&gt;. There will
-        be one render node per device. No ioctls except  PRIME-related ioctls
-        will be allowed on this node. Especially GEM_OPEN will be
-        explicitly prohibited. Render nodes are designed to avoid the
-        buffer-leaks, which occur if clients guess the flink names or mmap
-        offsets on the legacy interface. Additionally to this basic interface,
-        drivers must mark their driver-dependent render-only ioctls as
-        DRM_RENDER_ALLOW so render clients can use them. Driver
-        authors must be careful not to allow any privileged ioctls on render
-        nodes.
-      </para>
-      <para>
-        With render nodes, user-space can now control access to the render node
-        via basic file-system access-modes. A running graphics server which
-        authenticates clients on the privileged primary/legacy node is no longer
-        required. Instead, a client can open the render node and is immediately
-        granted GPU access. Communication between clients (or servers) is done
-        via PRIME. FLINK from render node to legacy node is not supported. New
-        clients must not use the insecure FLINK interface.
-      </para>
-      <para>
-        Besides dropping all modeset/global ioctls, render nodes also drop the
-        DRM-Master concept. There is no reason to associate render clients with
-        a DRM-Master as they are independent of any graphics server. Besides,
-        they must work without any running master, anyway.
-        Drivers must be able to run without a master object if they support
-        render nodes. If, on the other hand, a driver requires shared state
-        between clients which is visible to user-space and accessible beyond
-        open-file boundaries, they cannot support render nodes.

-<para>This system call opens a named audio device (e.g. /dev/dvb/adapter0/audio0)
- for subsequent use. When an open() call has succeeded, the device will be ready
- for use. The significance of blocking or non-blocking mode is described in the
- documentation for functions where there is a difference. It does not affect the
- semantics of the open() call itself. A device opened in blocking mode can later
- be put into non-blocking mode (and vice versa) using the F_SETFL command
- of the fcntl system call. This is a standard system call, documented in the Linux
- manual page for fcntl. Only one user can open the Audio Device in O_RDWR
- mode. All other attempts to open the device in this mode will fail, and an error
- code will be returned. If the Audio Device is opened in O_RDONLY mode, the
- only ioctl call that can be used is AUDIO_GET_STATUS. All other call will
- return with an error code.</para>

-<title>DVB Frontend properties</title>
-<para>Tuning into a Digital TV physical channel and starting decoding it
-    requires changing a set of parameters, in order to control the
-    tuner, the demodulator, the Linear Low-noise Amplifier (LNA) and to set the
-    antenna subsystem via Satellite Equipment Control (SEC), on satellite
-    systems. The actual parameters are specific to each particular digital
-    TV standards, and may change as the digital TV specs evolves.</para>
-<para>In the past, the strategy used was to have a union with the parameters
-    needed to tune for DVB-S, DVB-C, DVB-T and ATSC delivery systems grouped
-    there. The problem is that, as the second generation standards appeared,
-    those structs were not big enough to contain the additional parameters.
-    Also, the union didn't have any space left to be expanded without breaking
-    userspace. So, the decision was to deprecate the legacy union/struct based
-    approach, in favor of a properties set approach.</para>
-
-<para>NOTE: on Linux DVB API version 3, setting a frontend were done via
-    <link linkend="dvb-frontend-parameters">struct  <constant>dvb_frontend_parameters</constant></link>.
-    This got replaced on version 5 (also called "S2API", as this API were
-    added originally_enabled to provide support for DVB-S2), because the old
-    API has a very limited support to new standards and new hardware. This
-    section describes the new and recommended way to set the frontend, with
-    suppports all digital TV delivery systems.</para>
-
-<para>Example: with the properties based approach, in order to set the tuner
-    to a DVB-C channel at 651 kHz, modulated with 256-QAM, FEC 3/4 and symbol
-    rate of 5.217 Mbauds, those properties should be sent to

-
-		<para>Example: Assume 8 ISDB-Tsb connected segments are broadcasted. The

-			segments from position 1-8 to 5-13 or anything in between.</para>
-
-		<para>The underlying layer of segments are subchannels: each segment is

-			Television Broadcasting" and</para>
-		<para>ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial

-		<para>In order to understand the ISDB specific parameters,
-			one has to have some knowledge the channel structure in
-			ISDB-T and ISDB-Tsb. I.e. it has to be known to
-			the reader that an ISDB-T channel consists of 13 segments,
-			that it can have up to 3 layer sharing those segments,
-			and things like that.</para>

- system call. This is a standard system call, documented in the Linux manual

-<para>The kind of parameters passed to the frontend device for tuning depend on
-the kind of hardware you are using.</para>
-<para>The struct <constant>dvb_frontend_parameters</constant> uses an
-union with specific per-system parameters. However, as newer delivery systems
-required more data, the structure size weren't enough to fit, and just
-extending its size would break the existing applications. So, those parameters
-were replaced by the usage of <link linkend="FE_GET_PROPERTY">
-<constant>FE_GET_PROPERTY/FE_SET_PROPERTY</constant></link> ioctl's. The
-new API is flexible enough to add new parameters to existing delivery systems,
-and to add newer delivery systems.</para>
-<para>So, newer applications should use <link linkend="FE_GET_PROPERTY">
-<constant>FE_GET_PROPERTY/FE_SET_PROPERTY</constant></link> instead, in
-order to be able to support the newer System Delivery like  DVB-S2, DVB-T2,
-DVB-C2, ISDB, etc.</para>

-<para>In the case of QPSK frontends the <constant>frequency</constant> field specifies the intermediate
-frequency, i.e. the offset which is effectively added to the local oscillator frequency (LOF) of
-the LNB. The intermediate frequency has to be specified in units of kHz. For QAM and
-OFDM frontends the <constant>frequency</constant> specifies the absolute frequency and is given in Hz.

-<title>History</title>
-
-<para>The first API for DVB cards we used at Convergence in late 1999
-was an extension of the Video4Linux API which was primarily developed
-for frame grabber cards. As such it was not really well suited to be
-used for DVB cards and their new features like recording MPEG streams
-and filtering several section and PES data streams at the same time.
-</para>
-
-<para>In early 2000, we were approached by Nokia with a proposal for a
-new standard Linux DVB API. As a commitment to the development of
-terminals based on open standards, Nokia and Convergence made it
-available to all Linux developers and published it on
-<ulink url="https://linuxtv.org" /> in September 2000.
-Convergence is the maintainer of the Linux DVB API. Together with the
-LinuxTV community (i.e. you, the reader of this document), the Linux DVB
-API will be constantly reviewed and improved. With the Linux driver for
-the Siemens/Hauppauge DVB PCI card Convergence provides a first
-implementation of the Linux DVB API.</para>

- <listitem>
-
-<para>Frontend consisting of tuner and DVB demodulator</para>
-
-<para>Here the raw signal reaches the DVB hardware from a satellite dish
-or antenna or directly from cable. The frontend down-converts and
-demodulates this signal into an MPEG transport stream (TS). In case of a
-satellite frontend, this includes a facility for satellite equipment
-control (SEC), which allows control of LNB polarization, multi feed
-switches or dish rotors.</para>
-
-</listitem>
- <listitem>
-
-<para>Conditional Access (CA) hardware like CI adapters and smartcard slots
-</para>
-
-<para>The complete TS is passed through the CA hardware. Programs to
-which the user has access (controlled by the smart card) are decoded in
-real time and re-inserted into the TS.</para>
-
-</listitem>
- <listitem>
- <para>Demultiplexer which filters the incoming DVB stream</para>
-
-<para>The demultiplexer splits the TS into its components like audio and
-video streams. Besides usually several of such audio and video streams
-it also contains data streams with information about the programs
-offered in this or other streams of the same provider.</para>
-
-</listitem>
-<listitem>
-
-<para>MPEG2 audio and video decoder</para>
-
-<para>The main targets of the demultiplexer are the MPEG2 audio and
-video decoders. After decoding they pass on the uncompressed audio and
-video to the computer screen or (through a PAL/NTSC encoder) to a TV
-set.</para>

-
-<para><xref linkend="stb_components" /> shows a crude schematic of the control and data flow

-
-<para>On a DVB PCI card not all of these have to be present since some
-functionality can be provided by the main CPU of the PC (e.g. MPEG
-picture and sound decoding) or is not needed (e.g. for data-only uses
-like &#8220;internet over satellite&#8221;). Also not every card or STB
-provides conditional access hardware.</para>

-<title>Linux DVB Devices</title>
-
-<para>The Linux DVB API lets you control these hardware components
-through currently six Unix-style character devices for video, audio,
-frontend, demux, CA and IP-over-DVB networking. The video and audio
-devices control the MPEG2 decoder hardware, the frontend device the
-tuner and the DVB demodulator. The demux device gives you control over
-the PES and section filters of the hardware. If the hardware does not
-support filtering these filters can be implemented in software. Finally,
-the CA device controls all the conditional access capabilities of the
-hardware. It can depend on the individual security requirements of the
-platform, if and how many of the CA functions are made available to the
-application through this device.</para>

- The significance of blocking or non-blocking mode is described in the

- be put into non-blocking mode (and vice versa) using the F_SETFL command
- of the fcntl system call. This is a standard system call, documented in the Linux
- manual page for fcntl. Only one user can open the Video Device in O_RDWR

- error-code will be returned. If the Video Device is opened in O_RDONLY
- mode, the only ioctl call that can be used is VIDEO_GET_STATUS. All other

-    <title>Opening and Closing Devices</title>

-    <section>
-      <title>Device Naming</title>
-
-      <para>V4L2 drivers are implemented as kernel modules, loaded
-manually by the system administrator or automatically when a device is
-first discovered. The driver modules plug into the "videodev" kernel
-module. It provides helper functions and a common application
-interface specified in this document.</para>
-
-      <para>Each driver thus loaded registers one or more device nodes
-with major number 81 and a minor number between 0 and 255. Minor numbers
-are allocated dynamically unless the kernel is compiled with the kernel
-option CONFIG_VIDEO_FIXED_MINOR_RANGES. In that case minor numbers are
-allocated in ranges depending on the device node type (video, radio, etc.).</para>
-
-      <para>Many drivers support "video_nr", "radio_nr" or "vbi_nr"
-module options to select specific video/radio/vbi node numbers. This allows
-the user to request that the device node is named e.g. /dev/video5 instead
-of leaving it to chance. When the driver supports multiple devices of the same
-type more than one device node number can be assigned, separated by commas:
-	<informalexample>
-	  <screen>
-&gt; modprobe mydriver video_nr=0,1 radio_nr=0,1</screen>
-	</informalexample></para>
-
-      <para>In <filename>/etc/modules.conf</filename> this may be
-written as: <informalexample>
-	  <screen>
-options mydriver video_nr=0,1 radio_nr=0,1
-	  </screen>
-	</informalexample> When no device node number is given as module
-option the driver supplies a default.</para>
-
-      <para>Normally udev will create the device nodes in /dev automatically
-for you. If udev is not installed, then you need to enable the
-CONFIG_VIDEO_FIXED_MINOR_RANGES kernel option in order to be able to correctly
-relate a minor number to a device node number. I.e., you need to be certain
-that minor number 5 maps to device node name video5. With this kernel option
-different device types have different minor number ranges. These ranges are
-listed in <xref linkend="devices" />.
-</para>
-
-      <para>The creation of character special files (with
-<application>mknod</application>) is a privileged operation and
-devices cannot be opened by major and minor number. That means
-applications cannot <emphasis>reliable</emphasis> scan for loaded or
-installed drivers. The user must enter a device name, or the
-application can try the conventional device names.</para>

-    <section id="related">
-      <title>Related Devices</title>
-
-      <para>Devices can support several functions. For example
-video capturing, VBI capturing and radio support.</para>
-
-      <para>The V4L2 API creates different nodes for each of these functions.</para>
-
-      <para>The V4L2 API was designed with the idea that one device node could support
-all functions. However, in practice this never worked: this 'feature'
-was never used by applications and many drivers did not support it and if
-they did it was certainly never tested. In addition, switching a device
-node between different functions only works when using the streaming I/O
-API, not with the read()/write() API.</para>
-
-      <para>Today each device node supports just one function.</para>
-
-      <para>Besides video input or output the hardware may also
-support audio sampling or playback. If so, these functions are
-implemented as ALSA PCM devices with optional ALSA audio mixer
-devices.</para>
-
-      <para>One problem with all these devices is that the V4L2 API
-makes no provisions to find these related devices. Some really
-complex devices use the Media Controller (see <xref linkend="media_controller" />)
-which can be used for this purpose. But most drivers do not use it,
-and while some code exists that uses sysfs to discover related devices
-(see libmedia_dev in the <ulink url="http://git.linuxtv.org/cgit.cgi/v4l-utils.git/">v4l-utils</ulink>
-git repository), there is no library yet that can provide a single API towards
-both Media Controller-based devices and devices that do not use the Media Controller.
-If you want to work on this please write to the linux-media mailing list: &v4l-ml;.</para>
-    </section>
-
-    <section>
-      <title>Multiple Opens</title>
-
-      <para>V4L2 devices can be opened more than once.<footnote><para>
-There are still some old and obscure drivers that have not been updated to
-allow for multiple opens. This implies that for such drivers &func-open; can
-return an &EBUSY; when the device is already in use.</para></footnote>
-When this is supported by the driver, users can for example start a
-"panel" application to change controls like brightness or audio
-volume, while another application captures video and audio. In other words, panel
-applications are comparable to an ALSA audio mixer application.
-Just opening a V4L2 device should not change the state of the device.<footnote>
-<para>Unfortunately, opening a radio device often switches the state of the
-device to radio mode in many drivers. This behavior should be fixed eventually
-as it violates the V4L2 specification.</para></footnote></para>
-
-      <para>Once an application has allocated the memory buffers needed for
-streaming data (by calling the &VIDIOC-REQBUFS; or &VIDIOC-CREATE-BUFS; ioctls,
-or implicitly by calling the &func-read; or &func-write; functions) that
-application (filehandle) becomes the owner of the device. It is no longer
-allowed to make changes that would affect the buffer sizes (e.g. by calling
-the &VIDIOC-S-FMT; ioctl) and other applications are no longer allowed to allocate
-buffers or start or stop streaming. The &EBUSY; will be returned instead.</para>
-
-      <para>Merely opening a V4L2 device does not grant exclusive
-access.<footnote>
-	  <para>Drivers could recognize the
-<constant>O_EXCL</constant> open flag. Presently this is not required,
-so applications cannot know if it really works.</para>
-	</footnote> Initiating data exchange however assigns the right
-to read or write the requested type of data, and to change related
-properties, to this file descriptor. Applications can request
-additional access privileges using the priority mechanism described in
-<xref linkend="app-pri" />.</para>
-    </section>
-
-    <section>
-      <title>Shared Data Streams</title>
-
-      <para>V4L2 drivers should not support multiple applications
-reading or writing the same data stream on a device by copying
-buffers, time multiplexing or similar means. This is better handled by
-a proxy application in user space.</para>
-    </section>
-
-    <section>
-      <title>Functions</title>
-
-    <para>To open and close V4L2 devices applications use the
-&func-open; and &func-close; function, respectively. Devices are
-programmed using the &func-ioctl; function as explained in the
-following sections.</para>
-    </section>
-  </section>
-
-  <section id="querycap">
-    <title>Querying Capabilities</title>
-
-    <para>Because V4L2 covers a wide variety of devices not all
-aspects of the API are equally applicable to all types of devices.
-Furthermore devices of the same type have different capabilities and
-this specification permits the omission of a few complicated and less
-important parts of the API.</para>
-
-    <para>The &VIDIOC-QUERYCAP; ioctl is available to check if the kernel
-device is compatible with this specification, and to query the <link
-linkend="devices">functions</link> and <link linkend="io">I/O
-methods</link> supported by the device.</para>
-
-    <para>Starting with kernel version 3.1, VIDIOC-QUERYCAP will return the
-V4L2 API version used by the driver, with generally matches the Kernel version.
-There's no need of using &VIDIOC-QUERYCAP; to check if a specific ioctl is
-supported, the V4L2 core now returns ENOTTY if a driver doesn't provide
-support for an ioctl.</para>
-
-    <para>Other features can be queried
-by calling the respective ioctl, for example &VIDIOC-ENUMINPUT;
-to learn about the number, types and names of video connectors on the
-device. Although abstraction is a major objective of this API, the
-&VIDIOC-QUERYCAP; ioctl also allows driver specific applications to reliably identify
-the driver.</para>
-
-    <para>All V4L2 drivers must support
-<constant>VIDIOC_QUERYCAP</constant>. Applications should always call
-this ioctl after opening the device.</para>
-  </section>
-
-  <section id="app-pri">
-    <title>Application Priority</title>
-
-    <para>When multiple applications share a device it may be
-desirable to assign them different priorities. Contrary to the

-in particular an abundance of image formats. Although drivers must

-best the hardware can do to satisfy the request. Of course
-applications can also just query the current selection.</para>
-
-      <para>A single mechanism exists to negotiate all data formats
-using the aggregate &v4l2-format; and the &VIDIOC-G-FMT; and
-&VIDIOC-S-FMT; ioctls. Additionally the &VIDIOC-TRY-FMT; ioctl can be
-used to examine what the hardware <emphasis>could</emphasis> do,
-without actually selecting a new data format. The data formats
-supported by the V4L2 API are covered in the respective device section

-      <para>The <constant>VIDIOC_S_FMT</constant> ioctl is a major

-multiple panel applications can access the same device concurrently to

-The first <constant>VIDIOC_S_FMT</constant> assigns a logical stream
-(video data, VBI data etc.) exclusively to one file descriptor.</para>
-
-      <para>Exclusive means no other application, more precisely no

-properties inconsistent with the negotiated parameters. A video
-standard change for example, when the new standard uses a different
-number of scan lines, can invalidate the selected image format.
-Therefore only the file descriptor owning the stream can make
-invalidating changes. Accordingly multiple file descriptors which
-grabbed different logical streams prevent each other from interfering
-with their settings. When for example video overlay is about to start
-or already in progress, simultaneous video capturing may be restricted
-to the same cropping and image size.</para>
-

-Vertically ITU-R line

-
-      <para>The top left corner, width and height of the source
-rectangle, that is the area actually sampled, is given by &v4l2-crop;
-using the same coordinate system as &v4l2-cropcap;. Applications can
-use the <constant>VIDIOC_G_CROP</constant> and
-<constant>VIDIOC_S_CROP</constant> ioctls to get and set this
-rectangle. It must lie completely within the capture boundaries and
-the driver may further adjust the requested size and/or position
-according to hardware limitations.</para>
-
-      <para>Each capture device has a default source rectangle, given
-by the <structfield>defrect</structfield> substructure of
-&v4l2-cropcap;. The center of this rectangle shall align with the
-center of the active picture area of the video signal, and cover what
-the driver writer considers the complete picture. Drivers shall reset
-the source rectangle to the default when the driver is first loaded,
-but not later.</para>

-      <title>Scaling Adjustments</title>
-
-      <para>Video hardware can have various cropping, insertion and
-scaling limitations. It may only scale up or down, support only
-discrete scaling factors, or have different scaling abilities in
-horizontal and vertical direction. Also it may not support scaling at
-all. At the same time the &v4l2-crop; rectangle may have to be
-aligned, and both the source and target rectangles may have arbitrary
-upper and lower size limits. In particular the maximum
-<structfield>width</structfield> and <structfield>height</structfield>
-in &v4l2-crop; may be smaller than the
-&v4l2-cropcap;.<structfield>bounds</structfield> area. Therefore, as
-usual, drivers are expected to adjust the requested parameters and
-return the actual values selected.</para>
-
-      <para>Applications can change the source or the target rectangle
-first, as they may prefer a particular image size or a certain area in
-the video signal. If the driver has to adjust both to satisfy hardware
-limitations, the last requested rectangle shall take priority, and the
-driver should preferably adjust the opposite one. The &VIDIOC-TRY-FMT;
-ioctl however shall not change the driver state and therefore only
-adjust the requested rectangle.</para>
-
-      <para>Suppose scaling on a video capture device is restricted to
-a factor 1:1 or 2:1 in either direction and the target image size must
-be a multiple of 16&nbsp;&times;&nbsp;16 pixels. The source cropping
-rectangle is set to defaults, which are also the upper limit in this
-example, of 640&nbsp;&times;&nbsp;400 pixels at offset 0,&nbsp;0. An
-application requests an image size of 300&nbsp;&times;&nbsp;225
-pixels, assuming video will be scaled down from the "full picture"
-accordingly. The driver sets the image size to the closest possible
-values 304&nbsp;&times;&nbsp;224, then chooses the cropping rectangle
-closest to the requested size, that is 608&nbsp;&times;&nbsp;224
-(224&nbsp;&times;&nbsp;2:1 would exceed the limit 400). The offset
-0,&nbsp;0 is still valid, thus unmodified. Given the default cropping
-rectangle reported by <constant>VIDIOC_CROPCAP</constant> the
-application can easily propose another offset to center the cropping
-rectangle.</para>
-
-      <para>Now the application may insist on covering an area using a
-picture aspect ratio closer to the original request, so it asks for a
-cropping rectangle of 608&nbsp;&times;&nbsp;456 pixels. The present
-scaling factors limit cropping to 640&nbsp;&times;&nbsp;384, so the
-driver returns the cropping size 608&nbsp;&times;&nbsp;384 and adjusts
-the image size to closest possible 304&nbsp;&times;&nbsp;192.</para>

-	  linkend="v4l-dev" />.</para>
-
-      <para>The teletext devices (minor range 192-223) have been removed in
-V4L2 and no longer exist. There is no hardware available anymore for handling
-pure teletext. Instead raw or sliced VBI is used.</para>
-
-      <para>The V4L <filename>videodev</filename> module automatically
-assigns minor numbers to drivers in load order, depending on the
-registered device type. We recommend that V4L2 drivers by default
-register devices with the same numbers, but the system administrator

-criticised as too inflexible. In August 1998 Bill Dirks proposed a
-number of improvements and began to work on documentation, example
-drivers and applications. With the help of other volunteers this
-eventually became the V4L2 API, not just an extension but a
-replacement for the V4L API. However it took another four years and

-      <para>1998-09-18: The <constant>VIDIOC_NONCAP</constant> ioctl
-was replaced by the otherwise meaningless <constant>O_TRUNC</constant>
-&func-open; flag, and the aliases <constant>O_NONCAP</constant> and
-<constant>O_NOIO</constant> were defined. Applications can set this
-flag if they intend to access controls only, as opposed to capture
-applications which need exclusive access. The
-<constant>VIDEO_STD_XXX</constant> identifiers are now ordinals
-instead of flags, and the <function>video_std_construct()</function>
-helper function takes id and transmission arguments.</para>

-	  <para>The &v4l2-buffer; <structfield>timestamp</structfield>
-was changed to a 64 bit integer, containing the sampling or output
-time of the frame in nanoseconds. Additionally timestamps will be in
-absolute system time, not starting from zero at the beginning of a
-stream. The data type name for timestamps is stamp_t, defined as a
-signed 64-bit integer. Output devices should not send a buffer out
-until the time in the timestamp field has arrived. I would like to
-follow SGI's lead, and adopt a multimedia timestamping system like
-their UST (Unadjusted System Time). See
-http://web.archive.org/web/*/http://reality.sgi.com
-/cpirazzi_engr/lg/time/intro.html.
-UST uses timestamps that are 64-bit signed integers
-(not struct timeval's) and given in nanosecond units. The UST clock
-starts at zero when the system is booted and runs continuously and
-uniformly. It takes a little over 292 years for UST to overflow. There
-is no way to set the UST clock. The regular Linux time-of-day clock
-can be changed periodically, which would cause errors if it were being
-used for timestamping a multimedia stream. A real UST style clock will
-require some support in the kernel that is not there yet. But in
-anticipation, I will change the timestamp field to a 64-bit integer,
-and I will change the v4l2_masterclock_gettime() function (used only
-by drivers) to return a 64-bit integer.</para>

-        <title>X Video Extension</title>
-
-        <para>The X Video Extension (abbreviated XVideo or just Xv) is
-an extension of the X Window system, implemented for example by the
-XFree86 project. Its scope is similar to V4L2, an API to video capture
-and output devices for X clients. Xv allows applications to display
-live video in a window, send window contents to a TV output, and
-capture or output still images in XPixmaps<footnote>
-	  <para>This is not implemented in XFree86.</para>
-	</footnote>. With their implementation XFree86 makes the
-extension available across many operating systems and
-architectures.</para>
-
-        <para>Because the driver is embedded into the X server Xv has a
-number of advantages over the V4L2 <link linkend="overlay">video
-overlay interface</link>. The driver can easily determine the overlay
-target, &ie; visible graphics memory or off-screen buffers for a
-destructive overlay. It can program the RAMDAC for a non-destructive
-overlay, scaling or color-keying, or the clipping functions of the
-video capture hardware, always in sync with drawing operations or
-windows moving or changing their stacking order.</para>
-
-        <para>To combine the advantages of Xv and V4L a special Xv
-driver exists in XFree86 and XOrg, just programming any overlay capable
-Video4Linux device it finds. To enable it
-<filename>/etc/X11/XF86Config</filename> must contain these lines:</para>
-        <para><screen>
-Section "Module"
-    Load "v4l"
-EndSection</screen></para>
-
-        <para>As of XFree86 4.2 this driver still supports only V4L
-ioctls, however it should work just fine with all V4L2 devices through
-the V4L2 backward-compatibility layer. Since V4L2 permits multiple
-opens it is possible (if supported by the V4L2 driver) to capture
-video while an X client requested video overlay. Restrictions of
-simultaneous capturing and overlay are discussed in <xref
-	  linkend="overlay" /> apply.</para>
-
-        <para>Only marginally related to V4L2, XFree86 extended Xv to
-support hardware YUV to RGB conversion and scaling for faster video
-playback, and added an interface to MPEG-2 decoding hardware. This API
-is useful to display images captured with V4L2 devices.</para>

-    <title>User Controls</title>
-
-    <para>Devices typically have a number of user-settable controls
-such as brightness, saturation and so on, which would be presented to
-the user on a graphical user interface. But, different devices
-will have different controls available, and furthermore, the range of
-possible values, and the default value will vary from device to
-device. The control ioctls provide the information and a mechanism to
-create a nice user interface for these controls that will work
-correctly with any device.</para>
-
-    <para>All controls are accessed using an ID value. V4L2 defines
-several IDs for specific purposes. Drivers can also implement their
-own custom controls using <constant>V4L2_CID_PRIVATE_BASE</constant>
-<footnote><para>The use of <constant>V4L2_CID_PRIVATE_BASE</constant>
-is problematic because different drivers may use the same
-<constant>V4L2_CID_PRIVATE_BASE</constant> ID for different controls.
-This makes it hard to programatically set such controls since the meaning
-of the control with that ID is driver dependent. In order to resolve this
-drivers use unique IDs and the <constant>V4L2_CID_PRIVATE_BASE</constant>
-IDs are mapped to those unique IDs by the kernel. Consider these
-<constant>V4L2_CID_PRIVATE_BASE</constant> IDs as aliases to the real
-IDs.</para>
-<para>Many applications today still use the <constant>V4L2_CID_PRIVATE_BASE</constant>
-IDs instead of using &VIDIOC-QUERYCTRL; with the <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant>
-flag to enumerate all IDs, so support for <constant>V4L2_CID_PRIVATE_BASE</constant>
-is still around.</para></footnote>
-and higher values. The pre-defined control IDs have the prefix
-<constant>V4L2_CID_</constant>, and are listed in <xref
-linkend="control-id" />. The ID is used when querying the attributes of
-a control, and when getting or setting the current value.</para>
-
-    <para>Generally applications should present controls to the user
-without assumptions about their purpose. Each control comes with a
-name string the user is supposed to understand. When the purpose is
-non-intuitive the driver writer should provide a user manual, a user
-interface plug-in or a driver specific panel application. Predefined
-IDs were introduced to change a few controls programmatically, for
-example to mute a device during a channel switch.</para>
-
-    <para>Drivers may enumerate different controls after switching
-the current video input or output, tuner or modulator, or audio input
-or output. Different in the sense of other bounds, another default and
-current value, step size or other menu items. A control with a certain
-<emphasis>custom</emphasis> ID can also change name and
-type.</para>
-
-    <para>If a control is not applicable to the current configuration
-of the device (for example, it doesn't apply to the current video input)
-drivers set the <constant>V4L2_CTRL_FLAG_INACTIVE</constant> flag.</para>
-
-    <para>Control values are stored globally, they do not
-change when switching except to stay within the reported bounds. They
-also do not change &eg; when the device is opened or closed, when the
-tuner radio frequency is changed or generally never without
-application request.</para>
-
-    <para>V4L2 specifies an event mechanism to notify applications
-when controls change value (see &VIDIOC-SUBSCRIBE-EVENT;, event
-<constant>V4L2_EVENT_CTRL</constant>), panel applications might want to make
-use of that in order to always reflect the correct control value.</para>
-
-    <para>
-      All controls use machine endianness.

-

-      <title>Introduction</title>
-
-      <para>The control mechanism as originally designed was meant
-to be used for user settings (brightness, saturation, etc). However,
-it turned out to be a very useful model for implementing more
-complicated driver APIs where each driver implements only a subset of
-a larger API.</para>
-
-      <para>The MPEG encoding API was the driving force behind
-designing and implementing this extended control mechanism: the MPEG
-standard is quite large and the currently supported hardware MPEG
-encoders each only implement a subset of this standard. Further more,
-many parameters relating to how the video is encoded into an MPEG
-stream are specific to the MPEG encoding chip since the MPEG standard
-only defines the format of the resulting MPEG stream, not how the
-video is actually encoded into that format.</para>
-
-      <para>Unfortunately, the original control API lacked some
-features needed for these new uses and so it was extended into the
-(not terribly originally named) extended control API.</para>
-
-      <para>Even though the MPEG encoding API was the first effort
-to use the Extended Control API, nowadays there are also other classes
-of Extended Controls, such as Camera Controls and FM Transmitter Controls.
-The Extended Controls API as well as all Extended Controls classes are
-described in the following text.</para>
-    </section>
-
-    <section>
-      <title>The Extended Control API</title>
-
-      <para>Three new ioctls are available: &VIDIOC-G-EXT-CTRLS;,
-&VIDIOC-S-EXT-CTRLS; and &VIDIOC-TRY-EXT-CTRLS;. These ioctls act on
-arrays of controls (as opposed to the &VIDIOC-G-CTRL; and
-&VIDIOC-S-CTRL; ioctls that act on a single control). This is needed
-since it is often required to atomically change several controls at
-once.</para>
-
-      <para>Each of the new ioctls expects a pointer to a
-&v4l2-ext-controls;. This structure contains a pointer to the control
-array, a count of the number of controls in that array and a control
-class. Control classes are used to group similar controls into a
-single class. For example, control class
-<constant>V4L2_CTRL_CLASS_USER</constant> contains all user controls
-(&ie; all controls that can also be set using the old
-<constant>VIDIOC_S_CTRL</constant> ioctl). Control class
-<constant>V4L2_CTRL_CLASS_MPEG</constant> contains all controls
-relating to MPEG encoding, etc.</para>
-
-      <para>All controls in the control array must belong to the
-specified control class. An error is returned if this is not the
-case.</para>
-
-      <para>It is also possible to use an empty control array (count
-== 0) to check whether the specified control class is
-supported.</para>
-
-      <para>The control array is a &v4l2-ext-control; array. The
-<structname>v4l2_ext_control</structname> structure is very similar to
-&v4l2-control;, except for the fact that it also allows for 64-bit
-values and pointers to be passed.</para>
-
-      <para>Since the &v4l2-ext-control; supports pointers it is now
-also possible to have controls with compound types such as N-dimensional arrays
-and/or structures. You need to specify the <constant>V4L2_CTRL_FLAG_NEXT_COMPOUND</constant>
-when enumerating controls to actually be able to see such compound controls.
-In other words, these controls with compound types should only be used
-programmatically.</para>
-
-      <para>Since such compound controls need to expose more information
-about themselves than is possible with &VIDIOC-QUERYCTRL; the
-&VIDIOC-QUERY-EXT-CTRL; ioctl was added. In particular, this ioctl gives
-the dimensions of the N-dimensional array if this control consists of more than
-one element.</para>
-
-      <para>It is important to realize that due to the flexibility of
-controls it is necessary to check whether the control you want to set
-actually is supported in the driver and what the valid range of values
-is. So use the &VIDIOC-QUERYCTRL; (or &VIDIOC-QUERY-EXT-CTRL;) and
-&VIDIOC-QUERYMENU; ioctls to check this. Also note that it is possible
-that some of the menu indices in a control of type
-<constant>V4L2_CTRL_TYPE_MENU</constant> may not be supported
-(<constant>VIDIOC_QUERYMENU</constant> will return an error). A good
-example is the list of supported MPEG audio bitrates. Some drivers only
-support one or two bitrates, others support a wider range.</para>
-
-      <para>
-	All controls use machine endianness.
-      </para>

-    <section>
-      <title>Enumerating Extended Controls</title>
-
-      <para>The recommended way to enumerate over the extended
-controls is by using &VIDIOC-QUERYCTRL; in combination with the
-<constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> flag:</para>
-
-      <informalexample>
-	<programlisting>
-&v4l2-queryctrl; qctrl;
-
-qctrl.id = V4L2_CTRL_FLAG_NEXT_CTRL;
-while (0 == ioctl (fd, &VIDIOC-QUERYCTRL;, &amp;qctrl)) {
-	/* ... */
-	qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
-}
-</programlisting>
-      </informalexample>
-
-      <para>The initial control ID is set to 0 ORed with the
-<constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> flag. The
-<constant>VIDIOC_QUERYCTRL</constant> ioctl will return the first
-control with a higher ID than the specified one. When no such controls
-are found an error is returned.</para>
-
-      <para>If you want to get all controls within a specific control
-class, then you can set the initial
-<structfield>qctrl.id</structfield> value to the control class and add
-an extra check to break out of the loop when a control of another
-control class is found:</para>
-
-      <informalexample>
-	<programlisting>
-qctrl.id = V4L2_CTRL_CLASS_MPEG | V4L2_CTRL_FLAG_NEXT_CTRL;
-while (0 == ioctl(fd, &VIDIOC-QUERYCTRL;, &amp;qctrl)) {
-	if (V4L2_CTRL_ID2CLASS(qctrl.id) != V4L2_CTRL_CLASS_MPEG)
-		break;
-		/* ... */
-	qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
-}
-</programlisting>
-      </informalexample>

-actually part of the ID. The remaining 28 bits form the control ID, of
-which the most significant 12 bits define the control class and the
-least significant 16 bits identify the control within the control
-class. It is guaranteed that these last 16 bits are always non-zero
-for controls. The range of 0x1000 and up are reserved for
-driver-specific controls. The macro
-<constant>V4L2_CTRL_ID2CLASS(id)</constant> returns the control class
-ID based on a control ID.</para>

-Basically you will have to iterate over all controls using the method

-<constant>VIDIOC_QUERYCTRL</constant> will return the name of this
-control class which can be used as the title of a tab page within a

-      <para>Note that these devices can have multiple input or output pads which are

-      active when it comes to EDID (Extended Display Identification Data,
-      <xref linkend="vesaedid" />) and HDCP (High-bandwidth Digital Content
-      Protection System, <xref linkend="hdcp" />) processing, allowing the device
-      to do the fairly slow EDID/HDCP handling in advance. This allows for quick
-      switching between connectors.</para>
-
-      <para>These pads appear in several of the controls in this section as

-  <title>Video Overlay Interface</title>
-  <subtitle>Also known as Framebuffer Overlay or Previewing</subtitle>
-
-  <para>Video overlay devices have the ability to genlock (TV-)video
-into the (VGA-)video signal of a graphics card, or to store captured
-images directly in video memory of a graphics card, typically with
-clipping. This can be considerable more efficient than capturing
-images and displaying them by other means. In the old days when only
-nuclear power plants needed cooling towers this used to be the only
-way to put live video into a window.</para>
-
-  <para>Video overlay devices are accessed through the same character
-special files as <link linkend="capture">video capture</link> devices.
-Note the default function of a <filename>/dev/video</filename> device
-is video capturing. The overlay function is only available after
-calling the &VIDIOC-S-FMT; ioctl.</para>
-
-    <para>The driver may support simultaneous overlay and capturing
-using the read/write and streaming I/O methods. If so, operation at
-the nominal frame rate of the video standard is not guaranteed. Frames
-may be directed away from overlay to capture, or one field may be used
-for overlay and the other for capture if the capture parameters permit
-this.</para>
-
-  <para>Applications should use different file descriptors for
-capturing and overlay. This must be supported by all drivers capable
-of simultaneous capturing and overlay. Optionally these drivers may
-also permit capturing and overlay with a single file descriptor for
-compatibility with V4L and earlier versions of V4L2.<footnote>
-	<para>A common application of two file descriptors is the
-XFree86 <link linkend="xvideo">Xv/V4L</link> interface driver and
-a V4L2 application. While the X server controls video overlay, the
-application can take advantage of memory mapping and DMA.</para>
-	<para>In the opinion of the designers of this API, no driver
-writer taking the efforts to support simultaneous capturing and
-overlay will restrict this ability by requiring a single file
-descriptor, as in V4L and earlier versions of V4L2. Making this
-optional means applications depending on two file descriptors need
-backup routines to be compatible with all drivers, which is
-considerable more work than using two fds in applications which do
-not. Also two fd's fit the general concept of one file descriptor for
-each logical stream. Hence as a complexity trade-off drivers
-<emphasis>must</emphasis> support two file descriptors and

-&VIDIOC-G-FBUF; and &VIDIOC-S-FBUF; ioctls are available to get

-protection mechanisms of the kernel. Only the superuser can change the
-frame buffer address and size. Users are not supposed to run TV
-applications as root or with SUID bit set. A small helper application
-with suitable privileges should query the graphics system and program

-
-    <para>Some devices add the video overlay to the output signal

-
-    <para>The overlay window is described by a &v4l2-window;. It

-<constant>V4L2_BUF_TYPE_VIDEO_OVERLAY</constant>, initialize the

-  <title>Raw VBI Data Interface</title>
-
-  <para>VBI is an abbreviation of Vertical Blanking Interval, a gap
-in the sequence of lines of an analog video signal. During VBI
-no picture information is transmitted, allowing some time while the
-electron beam of a cathode ray tube TV returns to the top of the
-screen. Using an oscilloscope you will find here the vertical
-synchronization pulses and short data packages ASK
-modulated<footnote><para>ASK: Amplitude-Shift Keying. A high signal
-level represents a '1' bit, a low level a '0' bit.</para></footnote>
-onto the video signal. These are transmissions of services such as
-Teletext or Closed Caption.</para>
-
-  <para>Subject of this interface type is raw VBI data, as sampled off
-a video signal, or to be added to a signal for output.
-The data format is similar to uncompressed video images, a number of
-lines times a number of samples per line, we call this a VBI image.</para>
-
-  <para>Conventionally V4L2 VBI devices are accessed through character
-device special files named <filename>/dev/vbi</filename> and
-<filename>/dev/vbi0</filename> to <filename>/dev/vbi31</filename> with
-major number 81 and minor numbers 224 to 255.
-<filename>/dev/vbi</filename> is typically a symbolic link to the

-      <title>Raw VBI Format Negotiation</title>
-
-      <para>Raw VBI sampling abilities can vary, in particular the
-sampling frequency. To properly interpret the data V4L2 specifies an
-ioctl to query the sampling parameters. Moreover, to allow for some
-flexibility applications can also suggest different parameters.</para>
-
-      <para>As usual these parameters are <emphasis>not</emphasis>
-reset at &func-open; time to permit Unix tool chains, programming a
-device and then reading from it as if it was a plain file. Well
-written V4L2 applications should always ensure they really get what
-they want, requesting reasonable parameters and then checking if the
-actual parameters are suitable.</para>
-
-      <para>To query the current raw VBI capture parameters
-applications set the <structfield>type</structfield> field of a
-&v4l2-format; to <constant>V4L2_BUF_TYPE_VBI_CAPTURE</constant> or
-<constant>V4L2_BUF_TYPE_VBI_OUTPUT</constant>, and call the
-&VIDIOC-G-FMT; ioctl with a pointer to this structure. Drivers fill
-the &v4l2-vbi-format; <structfield>vbi</structfield> member of the
-<structfield>fmt</structfield> union.</para>
-
-      <para>To request different parameters applications set the
-<structfield>type</structfield> field of a &v4l2-format; as above and
-initialize all fields of the &v4l2-vbi-format;
-<structfield>vbi</structfield> member of the
-<structfield>fmt</structfield> union, or better just modify the
-results of <constant>VIDIOC_G_FMT</constant>, and call the
-&VIDIOC-S-FMT; ioctl with a pointer to this structure. Drivers return
-an &EINVAL; only when the given parameters are ambiguous, otherwise
-they modify the parameters according to the hardware capabilities and
-return the actual parameters. When the driver allocates resources at
-this point, it may return an &EBUSY; to indicate the returned
-parameters are valid but the required resources are currently not
-available. That may happen for instance when the video and VBI areas
-to capture would overlap, or when the driver supports multiple opens
-and another process already requested VBI capturing or output. Anyway,
-applications must expect other resource allocation points which may
-return <errorcode>EBUSY</errorcode>, at the &VIDIOC-STREAMON; ioctl
-and the first read(), write() and select() call.</para>
-
-      <para>VBI devices must implement both the
-<constant>VIDIOC_G_FMT</constant> and
-<constant>VIDIOC_S_FMT</constant> ioctl, even if
-<constant>VIDIOC_S_FMT</constant> ignores all requests and always
-returns default parameters as <constant>VIDIOC_G_FMT</constant> does.
-<constant>VIDIOC_TRY_FMT</constant> is optional.</para>

-All drivers implementing the sliced VBI interface must support this
-ioctl. The results may differ from those of the &VIDIOC-S-FMT; ioctl
-when the number of VBI lines the hardware can capture or output per
-frame, or the number of services it can identify on a given line are

-member and calling the &VIDIOC-S-FMT; ioctl with a pointer to the
-<structname>v4l2_format</structname> structure.</para>
-
-    <para>The sliced VBI API is more complicated than the raw VBI API
-because the hardware must be told which VBI service to expect on each
-scan line. Not all services may be supported by the hardware on all
-lines (this is especially true for VBI output where Teletext is often
-unsupported and other services can only be inserted in one specific
-line). In many cases, however, it is sufficient to just set the
-<structfield>service_set</structfield> field to the required services
-and let the driver fill the <structfield>service_lines</structfield>
-array according to hardware capabilities. Only if more precise control
-is needed should the programmer set the

-
-    <para>The &VIDIOC-S-FMT; ioctl modifies the parameters
-according to hardware capabilities. When the driver allocates
-resources at this point, it may return an &EBUSY; if the required
-resources are temporarily unavailable. Other resource allocation
-points which may return <errorcode>EBUSY</errorcode> can be the

-
-  <para>The complex nature of V4L2 devices, where hardware is often made of
-  several integrated circuits that need to interact with each other in a

-  the hardware model in software, and model the different hardware components
-  as software blocks called sub-devices.</para>
-
-  <para>V4L2 sub-devices are usually kernel-only objects. If the V4L2 driver
-  implements the media device API, they will automatically inherit from media
-  entities. Applications will be able to enumerate the sub-devices and discover
-  the hardware topology using the media entities, pads and links enumeration
-  API.</para>
-
-  <para>In addition to make sub-devices discoverable, drivers can also choose
-  to make them directly configurable by applications. When both the sub-device
-  driver and the V4L2 device driver support this, sub-devices will feature a

-    <para>Most V4L2 controls are implemented by sub-device hardware. Drivers
-    usually merge all controls and expose them through video device nodes.
-    Applications can control all sub-devices through a single interface.</para>
-
-    <para>Complex devices sometimes implement the same control in different
-    pieces of hardware. This situation is common in embedded platforms, where
-    both sensors and image processing hardware implement identical functions,
-    such as contrast adjustment, white balance or faulty pixels correction. As
-    the V4L2 controls API doesn't support several identical controls in a single
-    device, all but one of the identical controls are hidden.</para>
-
-    <para>Applications can access those hidden controls through the sub-device
-    node with the V4L2 control API described in <xref linkend="control" />. The
-    ioctls behave identically as when issued on V4L2 device nodes, with the
-    exception that they deal only with controls implemented in the sub-device.
-    </para>

-    <para>Depending on the driver, those controls might also be exposed through
-    one (or several) V4L2 device nodes.</para>

-    <title>Events</title>
-    <para>V4L2 sub-devices can notify applications of events as described in
-    <xref linkend="event" />. The API behaves identically as when used on V4L2
-    device nodes, with the exception that it only deals with events generated by

-    &VIDIOC-SUBDEV-S-FMT; ioctls. to negotiate formats on a per-pad basis.</para>
-
-    <para>Applications are responsible for configuring coherent parameters on
-    the whole pipeline and making sure that connected pads have compatible
-    formats. The pipeline is checked for formats mismatch at &VIDIOC-STREAMON;
-    time, and an &EPIPE; is then returned if the configuration is
-    invalid.</para>

-    <para>Pad-level image format configuration support can be tested by calling

-    pad-level format configuration is not supported by the sub-device.</para>

-      <title>Format Negotiation</title>
-
-      <para>Acceptable formats on pads can (and usually do) depend on a number
-      of external parameters, such as formats on other pads, active links, or
-      even controls. Finding a combination of formats on all pads in a video
-      pipeline, acceptable to both application and driver, can't rely on formats
-      enumeration only. A format negotiation mechanism is required.</para>
-
-      <para>Central to the format negotiation mechanism are the get/set format
-      operations. When called with the <structfield>which</structfield> argument
-      set to <constant>V4L2_SUBDEV_FORMAT_TRY</constant>, the
-      &VIDIOC-SUBDEV-G-FMT; and &VIDIOC-SUBDEV-S-FMT; ioctls operate on a set of
-      formats parameters that are not connected to the hardware configuration.
-      Modifying those 'try' formats leaves the device state untouched (this
-      applies to both the software state stored in the driver and the hardware
-      state stored in the device itself).</para>
-
-      <para>While not kept as part of the device state, try formats are stored
-      in the sub-device file handles. A &VIDIOC-SUBDEV-G-FMT; call will return
-      the last try format set <emphasis>on the same sub-device file
-      handle</emphasis>. Several applications querying the same sub-device at
-      the same time will thus not interact with each other.</para>
-
-      <para>To find out whether a particular format is supported by the device,
-      applications use the &VIDIOC-SUBDEV-S-FMT; ioctl. Drivers verify and, if
-      needed, change the requested <structfield>format</structfield> based on
-      device requirements and return the possibly modified value. Applications
-      can then choose to try a different format or accept the returned value and
-      continue.</para>
-
-      <para>Formats returned by the driver during a negotiation iteration are
-      guaranteed to be supported by the device. In particular, drivers guarantee
-      that a returned format will not be further changed if passed to an
-      &VIDIOC-SUBDEV-S-FMT; call as-is (as long as external parameters, such as
-      formats on other pads or links' configuration are not changed).</para>
-
-      <para>Drivers automatically propagate formats inside sub-devices. When a
-      try or active format is set on a pad, corresponding formats on other pads
-      of the same sub-device can be modified by the driver. Drivers are free to
-      modify formats as required by the device. However, they should comply with
-      the following rules when possible:
-      <itemizedlist>
-        <listitem><para>Formats should be propagated from sink pads to source pads.
-	Modifying a format on a source pad should not modify the format on any
-	sink pad.</para></listitem>
-        <listitem><para>Sub-devices that scale frames using variable scaling factors
-	should reset the scale factors to default values when sink pads formats
-	are modified. If the 1:1 scaling ratio is supported, this means that
-	source pads formats should be reset to the sink pads formats.</para></listitem>
-      </itemizedlist>
-      </para>
-
-      <para>Formats are not propagated across links, as that would involve
-      propagating them from one sub-device file handle to another. Applications
-      must then take care to configure both ends of every link explicitly with
-      compatible formats. Identical formats on the two ends of a link are
-      guaranteed to be compatible. Drivers are free to accept different formats
-      matching device requirements as being compatible.</para>

-      <title>Selections: cropping, scaling and composition</title>
-
-      <para>Many sub-devices support cropping frames on their input or output
-      pads (or possible even on both). Cropping is used to select the area of
-      interest in an image, typically on an image sensor or a video decoder. It can
-      also be used as part of digital zoom implementations to select the area of
-      the image that will be scaled up.</para>
-
-      <para>Crop settings are defined by a crop rectangle and represented in a
-      &v4l2-rect; by the coordinates of the top left corner and the rectangle
-      size. Both the coordinates and sizes are expressed in pixels.</para>
-
-      <para>As for pad formats, drivers store try and active
-      rectangles for the selection targets <xref
-      linkend="v4l2-selections-common" />.</para>
-
-      <para>On sink pads, cropping is applied relative to the
-      current pad format. The pad format represents the image size as
-      received by the sub-device from the previous block in the
-      pipeline, and the crop rectangle represents the sub-image that
-      will be transmitted further inside the sub-device for
-      processing.</para>
-
-      <para>The scaling operation changes the size of the image by
-      scaling it to new dimensions. The scaling ratio isn't specified
-      explicitly, but is implied from the original and scaled image
-      sizes. Both sizes are represented by &v4l2-rect;.</para>
-
-      <para>Scaling support is optional. When supported by a subdev,
-      the crop rectangle on the subdev's sink pad is scaled to the
-      size configured using the &VIDIOC-SUBDEV-S-SELECTION; IOCTL
-      using <constant>V4L2_SEL_TGT_COMPOSE</constant>
-      selection target on the same pad. If the subdev supports scaling
-      but not composing, the top and left values are not used and must
-      always be set to zero.</para>
-
-      <para>On source pads, cropping is similar to sink pads, with the
-      exception that the source size from which the cropping is
-      performed, is the COMPOSE rectangle on the sink pad. In both
-      sink and source pads, the crop rectangle must be entirely
-      contained inside the source image size for the crop
-      operation.</para>
-
-      <para>The drivers should always use the closest possible
-      rectangle the user requests on all selection targets, unless
-      specifically told otherwise.

-      The purpose of this License is to make a manual, textbook, or

-      freedom: to assure everyone the effective freedom to copy and
-      redistribute it, with or without modifying it, either
-      commercially or noncommercially. Secondarily, this License
-      preserves for the author and publisher a way to get credit for

-      This License is a kind of <quote>copyleft</quote>, which means

-
-    <para>
-      We have designed this License in order to use it for manuals for
-      free software, because free software needs free documentation: a
-      free program should come with manuals providing the same
-      freedoms that the software does. But this License is not limited
-      to software manuals; it can be used for any textual work,
-      regardless of subject matter or whether it is published as a
-      printed book. We recommend this License principally for works
-      whose purpose is instruction or reference.

-can suspend execution until the driver has captured data or is ready

-
-    <para>When streaming I/O has been negotiated this function waits

-with the &VIDIOC-DQBUF; ioctl. For output devices this function waits
-until the device is ready to accept a new buffer to be queued up with
-the &VIDIOC-QBUF; ioctl for display. When buffers are already in the outgoing
-queue of the driver (capture) or the incoming queue isn't full (display)
-the function returns immediately.</para>
-

-file descriptors that have been selected (that is, file descriptors
-for which the <structfield>revents</structfield> field of the
-respective <structname>pollfd</structname> structure is non-zero).
-Capture devices set the <constant>POLLIN</constant> and
-<constant>POLLRDNORM</constant> flags in the
-<structfield>revents</structfield> field, output devices the
-<constant>POLLOUT</constant> and <constant>POLLWRNORM</constant>
-flags. When the function timed out it returns a value of zero, on
-failure it returns <returnvalue>-1</returnvalue> and the

-<constant>POLLERR</constant> flag in the
-<structfield>revents</structfield> field. When the

-yet called &VIDIOC-QBUF;, the <function>poll()</function> function
-succeeds and sets the <constant>POLLERR</constant> flag in the
-<structfield>revents</structfield> field. For output devices this
-same situation will cause <function>poll()</function> to succeed
-as well, but it sets the <constant>POLLOUT</constant> and
-<constant>POLLWRNORM</constant> flags in the <structfield>revents</structfield>
-field.</para>
-
-    <para>If an event occurred (see &VIDIOC-DQEVENT;) then

-
-    <para>When use of the <function>read()</function> function has
-been negotiated and the driver does not capture yet, the
-<function>poll</function> function starts capturing. When that fails
-it returns a <constant>POLLERR</constant> as above. Otherwise it waits
-until data has been captured and can be read. When the driver captures
-continuously (as opposed to, for example, still images) the function
-may return immediately.</para>
-
-    <para>When use of the <function>write()</function> function has
-been negotiated and the driver does not stream yet, the
-<function>poll</function> function starts streaming. When that fails

-
-    <para><function>read()</function> attempts to read up to
-<parameter>count</parameter> bytes from file descriptor
-<parameter>fd</parameter> into the buffer starting at
-<parameter>buf</parameter>. The layout of the data in the buffer is
-discussed in the respective device interface section, see ##. If <parameter>count</parameter> is zero,
-<function>read()</function> returns zero and has no other results. If
-<parameter>count</parameter> is greater than
-<constant>SSIZE_MAX</constant>, the result is unspecified. Regardless
-of the <parameter>count</parameter> value each
-<function>read()</function> call will provide at most one frame (two
-fields) worth of data.</para>
-
-    <para>By default <function>read()</function> blocks until data
-becomes available. When the <constant>O_NONBLOCK</constant> flag was
-given to the &func-open; function it
-returns immediately with an &EAGAIN; when no data is available. The
-&func-select; or &func-poll; functions
-can always be used to suspend execution until data becomes available. All
-drivers supporting the <function>read()</function> function must also
-support <function>select()</function> and
-<function>poll()</function>.</para>
-
-    <para>Drivers can implement read functionality in different
-ways, using a single or multiple buffers and discarding the oldest or
-newest frames once the internal buffers are filled.</para>
-
-    <para><function>read()</function> never returns a "snapshot" of a
-buffer being filled. Using a single buffer the driver will stop
-capturing when the application starts reading the buffer until the
-read is finished. Thus only the period of the vertical blanking
-interval is available for reading, or the capture rate must fall below
-the nominal frame rate of the video standard.</para>
-
-<para>The behavior of
-<function>read()</function> when called during the active picture
-period or the vertical blanking separating the top and bottom field
-depends on the discarding policy. A driver discarding the oldest
-frames keeps capturing into an internal buffer, continuously
-overwriting the previously, not read frame, and returns the frame
-being received at the time of the <function>read()</function> call as
-soon as it is complete.</para>
-
-    <para>A driver discarding the newest frames stops capturing until
-the next <function>read()</function> call. The frame being received at
-<function>read()</function> time is discarded, returning the following
-frame instead. Again this implies a reduction of the capture rate to
-one half or less of the nominal frame rate. An example of this model
-is the video read mode of the bttv driver, initiating a DMA to user
-memory when <function>read()</function> is called and returning when
-the DMA finished.</para>
-
-    <para>In the multiple buffer model drivers maintain a ring of
-internal buffers, automatically advancing to the next free buffer.
-This allows continuous capturing when the application can empty the
-buffers fast enough. Again, the behavior when the driver runs out of
-free buffers depends on the discarding policy.</para>
-
-    <para>Applications can get and set the number of buffers used
-internally by the driver with the &VIDIOC-G-PARM; and &VIDIOC-S-PARM;
-ioctls. They are optional, however. The discarding policy is not
-reported and cannot be changed. For minimum requirements see <xref

-
-    <para>On success, the number of bytes read is returned. It is not
-an error if this number is smaller than the number of bytes requested,
-or the amount of data required for one frame. This may happen for
-example because <function>read()</function> was interrupted by a
-signal. On error, -1 is returned, and the <varname>errno</varname>
-variable is set appropriately. In this case the next read will start

-  <title>Input/Output</title>
-
-  <para>The V4L2 API defines several different methods to read from or
-write to a device. All drivers exchanging data with applications must
-support at least one of them.</para>
-
-  <para>The classic I/O method using the <function>read()</function>
-and <function>write()</function> function is automatically selected
-after opening a V4L2 device. When the driver does not support this
-method attempts to read or write will fail at any time.</para>
-
-  <para>Other methods must be negotiated. To select the streaming I/O
-method with memory mapped or user buffers applications call the
-&VIDIOC-REQBUFS; ioctl. The asynchronous I/O method is not defined
-yet.</para>
-
-  <para>Video overlay can be considered another I/O method, although
-the application does not directly receive the image data. It is
-selected by initiating video overlay with the &VIDIOC-S-FMT; ioctl.
-For more information see <xref linkend="overlay" />.</para>
-
-  <para>Generally exactly one I/O method, including overlay, is
-associated with each file descriptor. The only exceptions are
-applications not exchanging data with a driver ("panel applications",
-see <xref linkend="open" />) and drivers permitting simultaneous video capturing
-and overlay using the same file descriptor, for compatibility with V4L
-and earlier versions of V4L2.</para>
-
-  <para><constant>VIDIOC_S_FMT</constant> and
-<constant>VIDIOC_REQBUFS</constant> would permit this to some degree,
-but for simplicity drivers need not support switching the I/O method
-(after first switching away from read/write) other than by closing
-and reopening the device.</para>
-
-  <para>The following sections describe the various I/O methods in
-more detail.</para>
-
-  <section id="rw">
-    <title>Read/Write</title>
-
-    <para>Input and output devices support the
-<function>read()</function> and <function>write()</function> function,
-respectively, when the <constant>V4L2_CAP_READWRITE</constant> flag in
-the <structfield>capabilities</structfield> field of &v4l2-capability;
-returned by the &VIDIOC-QUERYCAP; ioctl is set.</para>
-
-    <para>Drivers may need the CPU to copy the data, but they may also
-support DMA to or from user memory, so this I/O method is not
-necessarily less efficient than other methods merely exchanging buffer
-pointers. It is considered inferior though because no meta-information
-like frame counters or timestamps are passed. This information is
-necessary to recognize frame dropping and to synchronize with other
-data streams. However this is also the simplest I/O method, requiring
-little or no setup to exchange data. It permits command line stunts
-like this (the <application>vidctrl</application> tool is
-fictitious):</para>

-</screen>
-    </informalexample>
-
-    <para>To read from the device applications use the
-&func-read; function, to write the &func-write; function.
-Drivers must implement one I/O method if they
-exchange data with applications, but it need not be this.<footnote>
-	<para>It would be desirable if applications could depend on
-drivers supporting all I/O interfaces, but as much as the complex
-memory mapping I/O can be inadequate for some devices we have no
-reason to require this interface, which is most useful for simple
-applications capturing still images.</para>
-      </footnote> When reading or writing is supported, the driver
-must also support the &func-select; and &func-poll;
-function.<footnote>
-	<para>At the driver level <function>select()</function> and
-<function>poll()</function> are the same, and
-<function>select()</function> is too important to be optional.</para>
-      </footnote></para>
-  </section>
-
-  <section id="mmap">
-    <title>Streaming I/O (Memory Mapping)</title>
-
-    <para>Input and output devices support this I/O method when the
-<constant>V4L2_CAP_STREAMING</constant> flag in the
-<structfield>capabilities</structfield> field of &v4l2-capability;
-returned by the &VIDIOC-QUERYCAP; ioctl is set. There are two
-streaming methods, to determine if the memory mapping flavor is
-supported applications must call the &VIDIOC-REQBUFS; ioctl.</para>
-
-    <para>Streaming is an I/O method where only pointers to buffers
-are exchanged between application and driver, the data itself is not
-copied. Memory mapping is primarily intended to map buffers in device
-memory into the application's address space. Device memory can be for
-example the video memory on a graphics card with a video capture
-add-on. However, being the most efficient I/O method available for a
-long time, many other drivers support streaming as well, allocating
-buffers in DMA-able main memory.</para>
-
-    <para>A driver can support many sets of buffers. Each set is
-identified by a unique buffer type value. The sets are independent and
-each set can hold a different type of data. To access different sets
-at the same time different file descriptors must be used.<footnote>
-	<para>One could use one file descriptor and set the buffer
-type field accordingly when calling &VIDIOC-QBUF; etc., but it makes
-the <function>select()</function> function ambiguous. We also like the
-clean approach of one file descriptor per logical stream. Video
-overlay for example is also a logical stream, although the CPU is not
-needed for continuous operation.</para>
-      </footnote></para>
-
-    <para>To allocate device buffers applications call the
-&VIDIOC-REQBUFS; ioctl with the desired number of buffers and buffer
-type, for example <constant>V4L2_BUF_TYPE_VIDEO_CAPTURE</constant>.
-This ioctl can also be used to change the number of buffers or to free
-the allocated memory, provided none of the buffers are still
-mapped.</para>
-
-    <para>Before applications can access the buffers they must map
-them into their address space with the &func-mmap; function. The
-location of the buffers in device memory can be determined with the
-&VIDIOC-QUERYBUF; ioctl. In the single-planar API case, the
-<structfield>m.offset</structfield> and <structfield>length</structfield>
-returned in a &v4l2-buffer; are passed as sixth and second parameter to the
-<function>mmap()</function> function. When using the multi-planar API,
-&v4l2-buffer; contains an array of &v4l2-plane; structures, each
-containing its own <structfield>m.offset</structfield> and
-<structfield>length</structfield>. When using the multi-planar API, every
-plane of every buffer has to be mapped separately, so the number of
-calls to &func-mmap; should be equal to number of buffers times number of
-planes in each buffer. The offset and length values must not be modified.
-Remember, the buffers are allocated in physical memory, as opposed to virtual
-memory, which can be swapped out to disk. Applications should free the buffers
-as soon as possible with the &func-munmap; function.</para>

-    <para>Conceptually streaming drivers maintain two buffer queues, an incoming
-and an outgoing queue. They separate the synchronous capture or output
-operation locked to a video clock from the application which is
-subject to random disk or network delays and preemption by
-other processes, thereby reducing the probability of data loss.
-The queues are organized as FIFOs, buffers will be
-output in the order enqueued in the incoming FIFO, and were
-captured in the order dequeued from the outgoing FIFO.</para>
-
-    <para>The driver may require a minimum number of buffers enqueued
-at all times to function, apart of this no limit exists on the number
-of buffers applications can enqueue in advance, or dequeue and
-process. They can also enqueue in a different order than buffers have
-been dequeued, and the driver can <emphasis>fill</emphasis> enqueued
-<emphasis>empty</emphasis> buffers in any order. <footnote>
-	<para>Random enqueue order permits applications processing
-images out of order (such as video codecs) to return buffers earlier,
-reducing the probability of data loss. Random fill order allows
-drivers to reuse buffers on a LIFO-basis, taking advantage of caches
-holding scatter-gather lists and the like.</para>
-      </footnote> The index number of a buffer (&v4l2-buffer;
-<structfield>index</structfield>) plays no role here, it only
-identifies the buffer.</para>
-
-    <para>Initially all mapped buffers are in dequeued state,
-inaccessible by the driver. For capturing applications it is customary
-to first enqueue all mapped buffers, then to start capturing and enter
-the read loop. Here the application waits until a filled buffer can be
-dequeued, and re-enqueues the buffer when the data is no longer
-needed. Output applications fill and enqueue buffers, when enough
-buffers are stacked up the output is started with
-<constant>VIDIOC_STREAMON</constant>. In the write loop, when
-the application runs out of free buffers, it must wait until an empty
-buffer can be dequeued and reused.</para>
-
-    <para>To enqueue and dequeue a buffer applications use the
-&VIDIOC-QBUF; and &VIDIOC-DQBUF; ioctl. The status of a buffer being
-mapped, enqueued, full or empty can be determined at any time using the

-    <title>Field Order</title>
-
-    <para>We have to distinguish between progressive and interlaced
-video. Progressive video transmits all lines of a video image
-sequentially. Interlaced video divides an image into two fields,
-containing only the odd and even lines of the image, respectively.
-Alternating the so called odd and even field are transmitted, and due
-to a small delay between fields a cathode ray TV displays the lines
-interleaved, yielding the original frame. This curious technique was
-invented because at refresh rates similar to film the image would
-fade out too quickly. Transmitting fields reduces the flicker without
-the necessity of doubling the frame rate and with it the bandwidth
-required for each channel.</para>
-
-    <para>It is important to understand a video camera does not expose
-one frame at a time, merely transmitting the frames separated into
-fields. The fields are in fact captured at two different instances in
-time. An object on screen may well move between one field and the
-next. For applications analysing motion it is of paramount importance
-to recognize which field of a frame is older, the <emphasis>temporal
-order</emphasis>.</para>
-
-    <para>When the driver provides or accepts images field by field
-rather than interleaved, it is also important applications understand
-how the fields combine to frames. We distinguish between top (aka odd) and
-bottom (aka even) fields, the <emphasis>spatial order</emphasis>: The first line
-of the top field is the first line of an interlaced frame, the first
-line of the bottom field is the second line of that frame.</para>
-
-    <para>However because fields were captured one after the other,
-arguing whether a frame commences with the top or bottom field is
-pointless. Any two successive top and bottom, or bottom and top fields
-yield a valid frame. Only when the source was progressive to begin
-with, &eg; when transferring film to video, two fields may come from
-the same frame, creating a natural order.</para>
-
-    <para>Counter to intuition the top field is not necessarily the
-older field. Whether the older field contains the top or bottom lines
-is a convention determined by the video standard. Hence the
-distinction between temporal and spatial order of fields. The diagrams
-below should make this clearer.</para>
-
-    <para>All video capture and output devices must report the current
-field order. Some drivers may permit the selection of a different
-order, to this end applications initialize the
-<structfield>field</structfield> field of &v4l2-pix-format; before
-calling the &VIDIOC-S-FMT; ioctl. If this is not desired it should
-have the value <constant>V4L2_FIELD_ANY</constant> (0).</para>

-<para>The LIRC device interface is a bi-directional interface for
-transporting raw IR data between userspace and kernelspace. Fundamentally,
-it is just a chardev (/dev/lircX, for X = 0, 1, 2, ...), with a number
-of standard struct file_operations defined on it. With respect to
-transporting raw IR data to and fro, the essential fops are read, write
-and ioctl.</para>

-<para>The lircd userspace daemon reads raw IR data from the LIRC chardev. The
-exact format of the data depends on what modes a driver supports, and what
-mode has been selected. lircd obtains supported modes and sets the active mode
-via the ioctl interface, detailed at <xref linkend="lirc_ioctl"/>. The generally
-preferred mode is LIRC_MODE_MODE2, in which packets containing an int value
-describing an IR signal are read from the chardev.</para>

-<title>LIRC write fop</title>
-
-<para>The data written to the chardev is a pulse/space sequence of integer
-values. Pulses and spaces are only marked implicitly by their position. The
-data must start and end with a pulse, therefore, the data must always include
-an uneven number of samples. The write function must block until the data has
-been transmitted by the hardware. If more data is provided than the hardware
-can send, the driver returns EINVAL.</para>

-<title>LIRC ioctl fop</title>
-
-<para>The LIRC device's ioctl definition is bound by the ioctl function
-definition of struct file_operations, leaving us with an unsigned int
-for the ioctl command and an unsigned long for the arg. For the purposes
-of ioctl portability across 32-bit and 64-bit, these values are capped
-to their 32-bit sizes.</para>

-In general each driver should have a default set of settings. The driver
-implementation is expected to re-apply the default settings when the device
-is closed by user-space, so that every application opening the device can rely
-on working with the default settings initially.</para>

-    <para>Media devices increasingly handle multiple related functions. Many USB
-    cameras include microphones, video capture hardware can also output video,
-    or SoC camera interfaces also perform memory-to-memory operations similar to
-    video codecs.</para>
-    <para>Independent functions, even when implemented in the same hardware, can
-    be modelled as separate devices. A USB camera with a microphone will be
-    presented to userspace applications as V4L2 and ALSA capture devices. The
-    devices' relationships (when using a webcam, end-users shouldn't have to
-    manually select the associated USB microphone), while not made available
-    directly to applications by the drivers, can usually be retrieved from
-    sysfs.</para>
-    <para>With more and more advanced SoC devices being introduced, the current
-    approach will not scale. Device topologies are getting increasingly complex
-    and can't always be represented by a tree structure. Hardware blocks are
-    shared between different functions, creating dependencies between seemingly
-    unrelated devices.</para>
-    <para>Kernel abstraction APIs such as V4L2 and ALSA provide means for
-    applications to access hardware parameters. As newer hardware expose an
-    increasingly high number of those parameters, drivers need to guess what
-    applications really require based on limited information, thereby
-    implementing policies that belong to userspace.</para>
-    <para>The media controller API aims at solving those problems.</para>

-    <para>Discovering a device internal topology, and configuring it at runtime,
-    is one of the goals of the media controller API. To achieve this, hardware

-    a System-on-Chip image processing pipeline), DMA channels or physical
-    connectors.</para></listitem>
-    <listitem><para>An <emphasis role="bold">interface</emphasis>

-    <listitem><para>A <emphasis role="bold">pad</emphasis>
-    is a data connection endpoint through which an entity can interact with
-    other entities. Data (not restricted to video) produced by an entity

-    <para>To enumerate pads and/or links for a given entity, applications set
-    the entity field of a &media-links-enum; structure and initialize the
-    &media-pad-desc; and &media-link-desc; structure arrays pointed by the
-    <structfield>pads</structfield> and <structfield>links</structfield> fields.
-    They then call the MEDIA_IOC_ENUM_LINKS ioctl with a pointer to this
-    structure.</para>
-    <para>If the <structfield>pads</structfield> field is not NULL, the driver
-    fills the <structfield>pads</structfield> array with information about the
-    entity's pads. The array must have enough room to store all the entity's
-    pads. The number of pads can be retrieved with the &MEDIA-IOC-ENUM-ENTITIES;
-    ioctl.</para>
-    <para>If the <structfield>links</structfield> field is not NULL, the driver
-    fills the <structfield>links</structfield> array with information about the
-    entity's outbound links. The array must have enough room to store all the
-    entity's outbound links. The number of outbound links can be retrieved with
-    the &MEDIA-IOC-ENUM-ENTITIES; ioctl.</para>
-    <para>Only forward links that originate at one of the entity's source pads
-    are returned during the enumeration process.</para>

-    at the ptr_entities, ptr_interfaces, ptr_links and/or ptr_pads, keeping
-    the other values untouched.</para>

-
-    <para>The usage and value of the alpha bits (a) in the ARGB and ABGR formats
-    (collectively referred to as alpha formats) depend on the device type and
-    hardware operation. <link linkend="capture">Capture</link> devices
-    (including capture queues of mem-to-mem devices) fill the alpha component in
-    memory. When the device outputs an alpha channel the alpha component will
-    have a meaningful value. Otherwise, when the device doesn't output an alpha
-    channel but can set the alpha bit to a user-configurable value, the <link
-    linkend="v4l2-alpha-component"><constant>V4L2_CID_ALPHA_COMPONENT</constant>
-    </link> control is used to specify that alpha value, and the alpha component
-    of all pixels will be set to the value specified by that control. Otherwise
-    a corresponding format without an alpha component (XRGB or XBGR) must be
-    used instead of an alpha format.</para>
-
-    <para><link linkend="output">Output</link> devices (including output queues
-    of mem-to-mem devices and <link linkend="osd">video output overlay</link>
-    devices) read the alpha component from memory. When the device processes the
-    alpha channel the alpha component must be filled with meaningful values by
-    applications. Otherwise a corresponding format without an alpha component
-    (XRGB or XBGR) must be used instead of an alpha format.</para>

-	<para>This is commonly the native format of digital cameras,
-reflecting the arrangement of sensors on the CCD device. Only one red,
-green or blue value is given for each pixel. Missing components must
-be interpolated from neighbouring pixels. From left to right the first
-row consists of a red and green value, the second row of a green and
-blue value. This scheme repeats to the right and down for every two
-columns and rows.</para>

-	<para>This format is not commonly used. This is a planar
-version of the YUYV format. The three components are separated into
-three sub-images or planes. The Y plane is first. The Y plane has one
-byte per pixel. The Cb plane immediately follows the Y plane in
-memory. The Cb plane is half the width of the Y plane (and of the
-image). Each Cb belongs to two pixels. For example,
-Cb<subscript>0</subscript> belongs to Y'<subscript>00</subscript>,
-Y'<subscript>01</subscript>. Following the Cb plane is the Cr plane,
-just like the Cb plane.</para>
-
-	<para>If the Y plane has pad bytes after each row, then the Cr
-and Cb planes have half as many pad bytes after their rows. In other
-words, two Cx rows (including padding) is exactly as long as one Y row
-(including padding).</para>

-    <title>Standard Image Formats</title>
-
-    <para>In order to exchange images between drivers and
-applications, it is necessary to have standard image data formats
-which both sides will interpret the same way. V4L2 includes several
-such formats, and this section is intended to be an unambiguous
-specification of the standard image data formats in V4L2.</para>
-
-    <para>V4L2 drivers are not limited to these formats, however.
-Driver-specific formats are possible. In that case the application may
-depend on a codec to convert images to one of the standard formats
-when needed. But the data can still be stored and retrieved in the
-proprietary format. For example, a device may support a proprietary
-compressed format. Applications can still capture and save the data in
-the compressed format, saving much disk space, and later use a codec
-to convert the images to the X Windows screen format when the video is
-to be displayed.</para>
-
-    <para>Even so, ultimately, some standard formats are needed, so
-the V4L2 specification would not be complete without well-defined
-standard formats.</para>
-
-    <para>The V4L2 standard formats are mainly uncompressed formats. The
-pixels are always arranged in memory from left to right, and from top
-to bottom. The first byte of data in the image buffer is always for
-the leftmost pixel of the topmost row. Following that is the pixel
-immediately to its right, and so on until the end of the top row of
-pixels. Following the rightmost pixel of the row there may be zero or
-more bytes of padding to guarantee that each row of pixel data has a
-certain alignment. Following the pad bytes, if any, is data for the
-leftmost pixel of the second row from the top, and so on. The last row
-has just as many pad bytes after it as the other rows.</para>
-
-    <para>In V4L2 each format has an identifier which looks like
-<constant>PIX_FMT_XXX</constant>, defined in the <link
-linkend="videodev">videodev2.h</link> header file. These identifiers
-represent <link linkend="v4l2-fourcc">four character (FourCC) codes</link>
-which are also listed below, however they are not the same as those
-used in the Windows world.</para>
-
-    <para>For some formats, data is stored in separate, discontiguous
-memory buffers. Those formats are identified by a separate set of FourCC codes
-and are referred to as "multi-planar formats". For example, a YUV422 frame is
-normally stored in one memory buffer, but it can also be placed in two or three
-separate buffers, with Y component in one buffer and CbCr components in another
-in the 2-planar version or with each component in its own buffer in the
-3-planar case. Those sub-buffers are referred to as "planes".</para>

-    <title>Colorspaces</title>
-
-    <para>'Color' is a very complex concept and depends on physics, chemistry and
-biology. Just because you have three numbers that describe the 'red', 'green'
-and 'blue' components of the color of a pixel does not mean that you can accurately
-display that color. A colorspace defines what it actually <emphasis>means</emphasis>
-to have an RGB value of e.g. (255,&nbsp;0,&nbsp;0). That is, which color should be
-reproduced on the screen in a perfectly calibrated environment.</para>
-
-    <para>In order to do that we first need to have a good definition of
-color, i.e. some way to uniquely and unambiguously define a color so that someone
-else can reproduce it. Human color vision is trichromatic since the human eye has
-color receptors that are sensitive to three different wavelengths of light. Hence
-the need to use three numbers to describe color. Be glad you are not a mantis shrimp
-as those are sensitive to 12 different wavelengths, so instead of RGB we would be
-using the ABCDEFGHIJKL colorspace...</para>
-
-    <para>Color exists only in the eye and brain and is the result of how strongly
-color receptors are stimulated. This is based on the Spectral
-Power Distribution (SPD) which is a graph showing the intensity (radiant power)
-of the light at wavelengths covering the visible spectrum as it enters the eye.
-The science of colorimetry is about the relationship between the SPD and color as
-perceived by the human brain.</para>
-
-    <para>Since the human eye has only three color receptors it is perfectly
-possible that different SPDs will result in the same stimulation of those receptors
-and are perceived as the same color, even though the SPD of the light is
-different.</para>
-
-   <para>In the 1920s experiments were devised to determine the relationship
-between SPDs and the perceived color and that resulted in the CIE 1931 standard
-that defines spectral weighting functions that model the perception of color.
-Specifically that standard defines functions that can take an SPD and calculate
-the stimulus for each color receptor. After some further mathematical transforms
-these stimuli are known as the <emphasis>CIE XYZ tristimulus</emphasis> values
-and these X, Y and Z values describe a color as perceived by a human unambiguously.
-These X, Y and Z values are all in the range [0&hellip;1].</para>
-
-   <para>The Y value in the CIE XYZ colorspace corresponds to luminance. Often
-the CIE XYZ colorspace is transformed to the normalized CIE xyY colorspace:</para>
-
-   <para>x = X / (X + Y + Z)</para>
-   <para>y = Y / (X + Y + Z)</para>
-
-   <para>The x and y values are the chromaticity coordinates and can be used to
-define a color without the luminance component Y. It is very confusing to
-have such similar names for these colorspaces. Just be aware that if colors
-are specified with lower case 'x' and 'y', then the CIE xyY colorspace is
-used. Upper case 'X' and 'Y' refer to the CIE XYZ colorspace. Also, y has nothing
-to do with luminance. Together x and y specify a color, and Y the luminance.
-That is really all you need to remember from a practical point of view. At
-the end of this section you will find reading resources that go into much more
-detail if you are interested.
-</para>
-
-   <para>A monitor or TV will reproduce colors by emitting light at three
-different wavelengths, the combination of which will stimulate the color receptors
-in the eye and thus cause the perception of color. Historically these wavelengths
-were defined by the red, green and blue phosphors used in the displays. These
-<emphasis>color primaries</emphasis> are part of what defines a colorspace.</para>
-
-    <para>Different display devices will have different primaries and some
-primaries are more suitable for some display technologies than others. This has
-resulted in a variety of colorspaces that are used for different display
-technologies or uses. To define a colorspace you need to define the three
-color primaries (these are typically defined as x,&nbsp;y chromaticity coordinates
-from the CIE xyY colorspace) but also the white reference: that is the color obtained
-when all three primaries are at maximum power. This determines the relative power
-or energy of the primaries. This is usually chosen to be close to daylight which has
-been defined as the CIE D65 Illuminant.</para>
-
-    <para>To recapitulate: the CIE XYZ colorspace uniquely identifies colors.
-Other colorspaces are defined by three chromaticity coordinates defined in the
-CIE xyY colorspace. Based on those a 3x3 matrix can be constructed that
-transforms CIE XYZ colors to colors in the new colorspace.
-</para>
-
-    <para>Both the CIE XYZ and the RGB colorspace that are derived from the
-specific chromaticity primaries are linear colorspaces. But neither the eye,
-nor display technology is linear. Doubling the values of all components in
-the linear colorspace will not be perceived as twice the intensity of the color.
-So each colorspace also defines a transfer function that takes a linear color
-component value and transforms it to the non-linear component value, which is a
-closer match to the non-linear performance of both the eye and displays. Linear
-component values are denoted RGB, non-linear are denoted as R'G'B'. In general
-colors used in graphics are all R'G'B', except in openGL which uses linear RGB.
-Special care should be taken when dealing with openGL to provide linear RGB colors
-or to use the built-in openGL support to apply the inverse transfer function.</para>
-
-    <para>The final piece that defines a colorspace is a function that
-transforms non-linear R'G'B' to non-linear Y'CbCr. This function is determined
-by the so-called luma coefficients. There may be multiple possible Y'CbCr
-encodings allowed for the same colorspace. Many encodings of color
-prefer to use luma (Y') and chroma (CbCr) instead of R'G'B'. Since the human
-eye is more sensitive to differences in luminance than in color this encoding
-allows one to reduce the amount of color information compared to the luma
-data. Note that the luma (Y') is unrelated to the Y in the CIE XYZ colorspace.
-Also note that Y'CbCr is often called YCbCr or YUV even though these are
-strictly speaking wrong.</para>
-
-    <para>Sometimes people confuse Y'CbCr as being a colorspace. This is not
-correct, it is just an encoding of an R'G'B' color into luma and chroma
-values. The underlying colorspace that is associated with the R'G'B' color
-is also associated with the Y'CbCr color.</para>
-
-    <para>The final step is how the RGB, R'G'B' or Y'CbCr values are
-quantized. The CIE XYZ colorspace where X, Y and Z are in the range
-[0&hellip;1] describes all colors that humans can perceive, but the transform to
-another colorspace will produce colors that are outside the [0&hellip;1] range.
-Once clamped to the [0&hellip;1] range those colors can no longer be reproduced
-in that colorspace. This clamping is what reduces the extent or gamut of the
-colorspace. How the range of [0&hellip;1] is translated to integer values in the
-range of [0&hellip;255] (or higher, depending on the color depth) is called the
-quantization. This is <emphasis>not</emphasis> part of the colorspace
-definition. In practice RGB or R'G'B' values are full range, i.e. they
-use the full [0&hellip;255] range. Y'CbCr values on the other hand are limited
-range with Y' using [16&hellip;235] and Cb and Cr using [16&hellip;240].</para>
-
-    <para>Unfortunately, in some cases limited range RGB is also used
-where the components use the range [16&hellip;235]. And full range Y'CbCr also exists
-using the [0&hellip;255] range.</para>
-
-    <para>In order to correctly interpret a color you need to know the
-quantization range, whether it is R'G'B' or Y'CbCr, the used Y'CbCr encoding
-and the colorspace.
-From that information you can calculate the corresponding CIE XYZ color
-and map that again to whatever colorspace your display device uses.</para>
-
-    <para>The colorspace definition itself consists of the three
-chromaticity primaries, the white reference chromaticity, a transfer
-function and the luma coefficients needed to transform R'G'B' to Y'CbCr. While
-some colorspace standards correctly define all four, quite often the colorspace
-standard only defines some, and you have to rely on other standards for
-the missing pieces. The fact that colorspaces are often a mix of different
-standards also led to very confusing naming conventions where the name of
-a standard was used to name a colorspace when in fact that standard was
-part of various other colorspaces as well.</para>
-
-    <para>If you want to read more about colors and colorspaces, then the
-following resources are useful: <xref linkend="poynton" /> is a good practical
-book for video engineers, <xref linkend="colimg" /> has a much broader scope and
-describes many more aspects of color (physics, chemistry, biology, etc.).
-The <ulink url="http://www.brucelindbloom.com">http://www.brucelindbloom.com</ulink>

-colorspace conversions. The wikipedia <ulink url="http://en.wikipedia.org/wiki/CIE_1931_color_space#CIE_xy_chromaticity_diagram_and_the_CIE_xyY_color_space">CIE 1931 colorspace</ulink> article

-    <title>Defining Colorspaces in V4L2</title>
-    <para>In V4L2 colorspaces are defined by four values. The first is the colorspace
-identifier (&v4l2-colorspace;) which defines the chromaticities, the default transfer
-function, the default Y'CbCr encoding and the default quantization method. The second
-is the transfer function identifier (&v4l2-xfer-func;) to specify non-standard
-transfer functions. The third is the Y'CbCr encoding identifier (&v4l2-ycbcr-encoding;)
-to specify non-standard Y'CbCr encodings and the fourth is the quantization identifier
-(&v4l2-quantization;) to specify non-standard quantization methods. Most of the time
-only the colorspace field of &v4l2-pix-format; or &v4l2-pix-format-mplane; needs to
-be filled in. Note that the default R'G'B' quantization is full range for all
-colorspaces except for BT.2020 which uses limited range R'G'B' quantization.</para>

-    <title>YUV Formats</title>
-
-    <para>YUV is the format native to TV broadcast and composite video
-signals. It separates the brightness information (Y) from the color
-information (U and V or Cb and Cr). The color information consists of
-red and blue <emphasis>color difference</emphasis> signals, this way
-the green component can be reconstructed by subtracting from the
-brightness component. See <xref linkend="colorspaces" /> for conversion
-examples. YUV was chosen because early television would only transmit
-brightness information. To add color in a way compatible with existing
-receivers a new signal carrier was added to transmit the color
-difference signals. Secondary in the YUV format the U and V components
-usually have lower resolution than the Y component. This is an analog
-video compression technique taking advantage of a property of the
-human visual system, being more sensitive to brightness
-information.</para>

-	    <entry>Two-planar format used by Samsung S5C73MX cameras. The
-first plane contains interleaved JPEG and UYVY image data, followed by meta data
-in form of an array of offsets to the UYVY data blocks. The actual pointer array
-follows immediately the interleaved JPEG/UYVY data, the number of entries in
-this array equals the height of the UYVY image. Each entry is a 4-byte unsigned
-integer in big endian order and it's an offset to a single pixel line of the
-UYVY image. The first plane can start either with JPEG or UYVY data chunk. The
-size of a single UYVY block equals the UYVY image's width multiplied by 2. The
-size of a JPEG chunk depends on the image and can vary with each line.
-<para>The second plane, at an offset of 4084 bytes, contains a 4-byte offset to
-the pointer array in the first plane. This offset is followed by a 4-byte value
-indicating size of the pointer array. All numbers in the second plane are also
-in big endian order. Remaining data in the second plane is undefined. The
-information in the second plane allows to easily find location of the pointer
-array, which can be different for each frame. The size of the pointer array is
-constant for given UYVY image height.</para>
-<para>In order to extract UYVY and JPEG frames an application can initially set
-a data pointer to the start of first plane and then add an offset from the first
-entry of the pointers table. Such a pointer indicates start of an UYVY image
-pixel line. Whole UYVY line can be copied to a separate buffer. These steps
-should be repeated for each line, i.e. the number of entries in the pointer
-array. Anything what's in between the UYVY lines is JPEG data and should be
-concatenated to form the JPEG stream. </para>

-  <para>Some devices require data for each input or output video frame
-  to be placed in discontiguous memory buffers. In such cases, one
-  video frame has to be addressed using more than one memory address, i.e. one

-  <para>Some of the V4L2 API calls and structures are interpreted differently,
-  depending on whether single- or multi-planar API is being used. An application
-  can choose whether to use one or the other by passing a corresponding buffer

-<para>Currently, most analog and digital devices have a Infrared input for remote controllers. Each
-manufacturer has their own type of control. It is not rare for the same manufacturer to ship different
-types of controls, depending on the device.</para>
-<para>A Remote Controller interface is mapped as a normal evdev/input interface, just like a keyboard or a mouse.
-So, it uses all ioctls already defined for any other input devices.</para>
-<para>However, remove controllers are more flexible than a normal input device, as the IR
-receiver (and/or transmitter) can be used in conjunction with a wide variety of different IR remotes.</para>

-<title>Remote controller tables</title>
-<para>Unfortunately, for several years, there was no effort to create uniform IR keycodes for
-different devices.  This caused the same IR keyname to be mapped completely differently on
-different IR devices. This resulted that the same IR keyname to be mapped completely different on
-different IR's. Due to that, V4L2 API now specifies a standard for mapping Media keys on IR.</para>
-<para>This standard should be used by both V4L/DVB drivers and userspace applications</para>
-<para>The modules register the remote as keyboard within the linux input layer. This means that the IR key strokes will look like normal keyboard key strokes (if CONFIG_INPUT_KEYBOARD is enabled). Using the event devices (CONFIG_INPUT_EVDEV) it is possible for applications to access the remote via /dev/input/event devices.</para>

-<para>Some video capture devices can sample a subsection of a picture and

-scaling and composing.</para>

-
-<para>On a video <emphasis>output</emphasis> device the source is an image in a

-position of such a window is controlled by the compose target.</para>
-
-<para>Rectangles for all cropping and composing targets are defined even if the

-
-<para>Applications can use the <link linkend="vidioc-g-selection">selection
-API</link> to select an area in a video signal or a buffer, and to query for
-default settings and hardware limits.</para>
-
-<para>Video hardware can have various cropping, composing and scaling
-limitations. It may only scale up or down, support only discrete scaling
-factors, or have different scaling abilities in the horizontal and vertical
-directions. Also it may not support scaling at all. At the same time the
-cropping/composing rectangles may have to be aligned, and both the source and
-the sink may have arbitrary upper and lower size limits. Therefore, as usual,
-drivers are expected to adjust the requested parameters and return the actual
-values selected. An application can control the rounding behaviour using <link
-linkend="v4l2-selection-flags"> constraint flags </link>.</para>

-   <title>Configuration of video capture</title>
-
-<para>See figure <xref linkend="sel-targets-capture" /> for examples of the
-selection targets available for a video capture device.  It is recommended to
-configure the cropping targets before to the composing targets.</para>
-
-<para>The range of coordinates of the top left corner, width and height of
-areas that can be sampled is given by the <constant>V4L2_SEL_TGT_CROP_BOUNDS</constant>
-target. It is recommended for the driver developers to put the
-top/left corner at position <constant>(0,0)</constant>.  The rectangle's
-coordinates are expressed in pixels.</para>
-
-<para>The top left corner, width and height of the source rectangle, that is
-the area actually sampled, is given by the <constant>V4L2_SEL_TGT_CROP</constant>
-target. It uses the same coordinate system as <constant>V4L2_SEL_TGT_CROP_BOUNDS</constant>.
-The active cropping area must lie completely inside the capture boundaries. The
-driver may further adjust the requested size and/or position according to hardware
-limitations.</para>
-
-<para>Each capture device has a default source rectangle, given by the
-<constant>V4L2_SEL_TGT_CROP_DEFAULT</constant> target. This rectangle shall
-over what the driver writer considers the complete picture.  Drivers shall set
-the active crop rectangle to the default when the driver is first loaded, but
-not later.</para>
-
-<para>The composing targets refer to a memory buffer. The limits of composing
-coordinates are obtained using <constant>V4L2_SEL_TGT_COMPOSE_BOUNDS</constant>.
-All coordinates are expressed in pixels. The rectangle's top/left
-corner must be located at position <constant>(0,0)</constant>. The width and
-height are equal to the image size set by <constant>VIDIOC_S_FMT</constant>.
-</para>
-
-<para>The part of a buffer into which the image is inserted by the hardware is
-controlled by the <constant>V4L2_SEL_TGT_COMPOSE</constant> target.
-The rectangle's coordinates are also expressed in the same coordinate system as
-the bounds rectangle. The composing rectangle must lie completely inside bounds
-rectangle. The driver must adjust the composing rectangle to fit to the
-bounding limits. Moreover, the driver can perform other adjustments according
-to hardware limitations. The application can control rounding behaviour using
-<link linkend="v4l2-selection-flags"> constraint flags</link>.</para>
-
-<para>For capture devices the default composing rectangle is queried using
-<constant>V4L2_SEL_TGT_COMPOSE_DEFAULT</constant>. It is usually equal to the
-bounding rectangle.</para>
-
-<para>The part of a buffer that is modified by the hardware is given by
-<constant>V4L2_SEL_TGT_COMPOSE_PADDED</constant>. It contains all pixels
-defined using <constant>V4L2_SEL_TGT_COMPOSE</constant> plus all
-padding data modified by hardware during insertion process. All pixels outside
-this rectangle <emphasis>must not</emphasis> be changed by the hardware. The
-content of pixels that lie inside the padded area but outside active area is
-undefined. The application can use the padded and active rectangles to detect
-where the rubbish pixels are located and remove them if needed.</para>

-   <section>
-
-   <title>Configuration of video output</title>
-
-<para>For output devices targets and ioctls are used similarly to the video
-capture case. The <emphasis>composing</emphasis> rectangle refers to the
-insertion of an image into a video signal. The cropping rectangles refer to a
-memory buffer. It is recommended to configure the composing targets before to
-the cropping targets.</para>
-
-<para>The cropping targets refer to the memory buffer that contains an image to
-be inserted into a video signal or graphical screen. The limits of cropping
-coordinates are obtained using <constant>V4L2_SEL_TGT_CROP_BOUNDS</constant>.
-All coordinates are expressed in pixels. The top/left corner is always point
-<constant>(0,0)</constant>.  The width and height is equal to the image size
-specified using <constant>VIDIOC_S_FMT</constant> ioctl.</para>
-
-<para>The top left corner, width and height of the source rectangle, that is
-the area from which image date are processed by the hardware, is given by the
-<constant>V4L2_SEL_TGT_CROP</constant>. Its coordinates are expressed
-in in the same coordinate system as the bounds rectangle. The active cropping
-area must lie completely inside the crop boundaries and the driver may further
-adjust the requested size and/or position according to hardware
-limitations.</para>
-
-<para>For output devices the default cropping rectangle is queried using
-<constant>V4L2_SEL_TGT_CROP_DEFAULT</constant>. It is usually equal to the
-bounding rectangle.</para>
-
-<para>The part of a video signal or graphics display where the image is
-inserted by the hardware is controlled by <constant>V4L2_SEL_TGT_COMPOSE</constant>
-target.  The rectangle's coordinates are expressed in pixels. The composing
-rectangle must lie completely inside the bounds rectangle.  The driver must
-adjust the area to fit to the bounding limits.  Moreover, the driver can
-perform other adjustments according to hardware limitations.</para>
-
-<para>The device has a default composing rectangle, given by the
-<constant>V4L2_SEL_TGT_COMPOSE_DEFAULT</constant> target. This rectangle shall cover what
-the driver writer considers the complete picture. It is recommended for the
-driver developers to put the top/left corner at position <constant>(0,0)</constant>.
-Drivers shall set the active composing rectangle to the default
-one when the driver is first loaded.</para>
-
-<para>The devices may introduce additional content to video signal other than
-an image from memory buffers.  It includes borders around an image. However,
-such a padded area is driver-dependent feature not covered by this document.
-Driver developers are encouraged to keep padded rectangle equal to active one.
-The padded target is accessed by the <constant>V4L2_SEL_TGT_COMPOSE_PADDED</constant>
-identifier.  It must contain all pixels from the <constant>V4L2_SEL_TGT_COMPOSE</constant>
-target.</para>

-
-   <section>
-
-     <title>Scaling control</title>
-
-<para>An application can detect if scaling is performed by comparing the width
-and the height of rectangles obtained using <constant>V4L2_SEL_TGT_CROP</constant>
-and <constant>V4L2_SEL_TGT_COMPOSE</constant> targets. If
-these are not equal then the scaling is applied. The application can compute
-the scaling ratios using these values.</para>

-    <title>Comparison with old cropping API</title>
-
-<para>The selection API was introduced to cope with deficiencies of previous
-<link linkend="crop"> API</link>, that was designed to control simple capture
-devices. Later the cropping API was adopted by video output drivers. The ioctls
-are used to select a part of the display were the video signal is inserted. It
-should be considered as an API abuse because the described operation is
-actually the composing.  The selection API makes a clear distinction between
-composing and cropping operations by setting the appropriate targets.  The V4L2
-API lacks any support for composing to and cropping from an image inside a
-memory buffer.  The application could configure a capture device to fill only a
-part of an image by abusing V4L2 API.  Cropping a smaller image from a larger
-one is achieved by setting the field
-&v4l2-pix-format;<structfield>::bytesperline</structfield>.  Introducing an image offsets
-could be done by modifying field &v4l2-buffer;<structfield>::m_userptr</structfield>
-before calling <constant>VIDIOC_QBUF</constant>. Those
-operations should be avoided because they are not portable (endianness), and do
-not work for macroblock and Bayer formats and mmap buffers.  The selection API
-deals with configuration of buffer cropping/composing in a clear, intuitive and
-portable way.  Next, with the selection API the concepts of the padded target
-and constraints flags are introduced.  Finally, &v4l2-crop; and &v4l2-cropcap;
-have no reserved fields. Therefore there is no way to extend their functionality.
-The new &v4l2-selection; provides a lot of place for future
-extensions.  Driver developers are encouraged to implement only selection API.
-The former cropping API would be simulated using the new one.</para>

-    <title>Media Bus Pixel Codes</title>
-
-    <para>The media bus pixel codes describe image formats as flowing over
-    physical busses (both between separate physical components and inside SoC
-    devices). This should not be confused with the V4L2 pixel formats that
-    describe, using four character codes, image formats as stored in memory.
-    </para>
-
-    <para>While there is a relationship between image formats on busses and
-    image formats in memory (a raw Bayer image won't be magically converted to
-    JPEG just by storing it to memory), there is no one-to-one correspondance
-    between them.</para>
-
-    <section>
-      <title>Packed RGB Formats</title>
-
-      <para>Those formats transfer pixel data as red, green and blue components.
-      The format code is made of the following information.
-      <itemizedlist>
-	<listitem><para>The red, green and blue components order code, as encoded in a
-	pixel sample. Possible values are RGB and BGR.</para></listitem>
-	<listitem><para>The number of bits per component, for each component. The values
-	can be different for all components. Common values are 555 and 565.</para>
-	</listitem>
-	<listitem><para>The number of bus samples per pixel. Pixels that are wider than
-	the bus width must be transferred in multiple samples. Common values are
-	1 and 2.</para></listitem>
-	<listitem><para>The bus width.</para></listitem>
-	<listitem><para>For formats where the total number of bits per pixel is smaller
-	than the number of bus samples per pixel times the bus width, a padding
-	value stating if the bytes are padded in their most high order bits
-	(PADHI) or low order bits (PADLO). A "C" prefix is used for component-wise
-	padding in the most high order bits (CPADHI) or low order bits (CPADLO)
-	of each separate component.</para></listitem>
-	<listitem><para>For formats where the number of bus samples per pixel is larger
-	than 1, an endianness value stating if the pixel is transferred MSB first
-	(BE) or LSB first (LE).</para></listitem>
-      </itemizedlist>
-      </para>
-
-      <para>For instance, a format where pixels are encoded as 5-bits red, 5-bits
-      green and 5-bit blue values padded on the high bit, transferred as 2 8-bit
-      samples per pixel with the most significant bits (padding, red and half of
-      the green value) transferred first will be named
-      <constant>MEDIA_BUS_FMT_RGB555_2X8_PADHI_BE</constant>.

-      <para>On LVDS buses, usually each sample is transferred serialized in
-      seven time slots per pixel clock, on three (18-bit) or four (24-bit)
-      differential data pairs at the same time. The remaining bits are used for
-      control signals as defined by SPWG/PSWG/VESA or JEIDA standards.

-
-      <para>Those data formats transfer pixel data as (possibly downsampled) Y, U
-      and V components. Some formats include dummy bits in some of their samples
-      and are collectively referred to as "YDYC" (Y-Dummy-Y-Chroma) formats.
-      One cannot rely on the values of these dummy bits as those are undefined.
-      </para>
-      <para>The format code is made of the following information.
-      <itemizedlist>
-	<listitem><para>The Y, U and V components order code, as transferred on the
-	bus. Possible values are YUYV, UYVY, YVYU and VYUY for formats with no
-	dummy bit, and YDYUYDYV, YDYVYDYU, YUYDYVYD and YVYDYUYD for YDYC formats.
-	</para></listitem>
-	<listitem><para>The number of bits per pixel component. All components are
-	transferred on the same number of bits. Common values are 8, 10 and 12.</para>
-	</listitem>
-	<listitem><para>The number of bus samples per pixel. Pixels that are wider than
-	the bus width must be transferred in multiple samples. Common values are
-	1, 1.5 (encoded as 1_5) and 2.</para></listitem>
-	<listitem><para>The bus width. When the bus width is larger than the number of
-	bits per pixel component, several components are packed in a single bus
-	sample. The components are ordered as specified by the order code, with
-	components on the left of the code transferred in the high order bits.
-	Common values are 8 and 16.</para>
-	</listitem>
-      </itemizedlist>
-      </para>
-
-      <para>For instance, a format where pixels are encoded as 8-bit YUV values
-      downsampled to 4:2:2 and transferred as 2 8-bit bus samples per pixel in the
-      U, Y, V, Y order will be named <constant>MEDIA_BUS_FMT_UYVY8_2X8</constant>.
-      </para>
-
-	<para><xref linkend="v4l2-mbus-pixelcode-yuv8"/> lists existing packed YUV
-	formats and describes the organization of each pixel data in each sample.
-	When a format pattern is split across multiple samples each of the samples
-	in the pattern is described.</para>
-
-	<para>The role of each bit transferred over the bus is identified by one
-	of the following codes.</para>

-
-    <para>This ioctl is used to create buffers for <link linkend="mmap">memory
-mapped</link> or <link linkend="userp">user pointer</link> or <link
-linkend="dmabuf">DMA buffer</link> I/O. It can be used as an alternative or in
-addition to the &VIDIOC-REQBUFS; ioctl, when a tighter
-control over buffers is required. This ioctl can be called multiple times to
-create buffers of different sizes.</para>
-
-    <para>To allocate the device buffers applications must initialize the
-relevant fields of the <structname>v4l2_create_buffers</structname> structure.
-The <structfield>count</structfield> field must be set to the number of
-requested buffers, the <structfield>memory</structfield> field specifies the
-requested I/O method and the <structfield>reserved</structfield> array must be
-zeroed.</para>
-
-    <para>The <structfield>format</structfield> field specifies the image format
-that the buffers must be able to handle. The application has to fill in this
-&v4l2-format;. Usually this will be done using the &VIDIOC-TRY-FMT; or &VIDIOC-G-FMT; ioctls
-to ensure that the requested format is supported by the driver.
-Based on the format's <structfield>type</structfield> field the requested buffer
-size (for single-planar) or plane sizes (for multi-planar formats) will be
-used for the allocated buffers. The driver may return an error if the size(s)
-are not supported by the hardware (usually because they are too small).</para>
-
-    <para>The buffers created by this ioctl will have as minimum size the size
-defined by the <structfield>format.pix.sizeimage</structfield> field (or the
-corresponding fields for other format types). Usually if the
-<structfield>format.pix.sizeimage</structfield> field is less than the minimum
-required for the given format, then an error will be returned since drivers will
-typically not allow this. If it is larger, then the value will be used as-is.
-In other words, the driver may reject the requested size, but if it is accepted
-the driver will use it unchanged.</para>
-
-    <para>When the ioctl is called with a pointer to this structure the driver
-will attempt to allocate up to the requested number of buffers and store the
-actual number allocated and the starting index in the
-<structfield>count</structfield> and the <structfield>index</structfield> fields
-respectively. On return <structfield>count</structfield> can be smaller than
-the number requested.</para>

-    </note>
-
-    <para>For driver debugging purposes these ioctls allow test
-applications to access hardware registers directly. Regular
-applications must not use them.</para>
-
-    <para>Since writing or even reading registers can jeopardize the
-system security, its stability and damage the hardware, both ioctls
-require superuser privileges. Additionally the Linux kernel must be
-compiled with the <constant>CONFIG_VIDEO_ADV_DEBUG</constant> option
-to enable these ioctls.</para>
-
-    <para>To write a register applications must initialize all fields
-of a &v4l2-dbg-register; except for <structfield>size</structfield> and call
-<constant>VIDIOC_DBG_S_REGISTER</constant> with a pointer to this
-structure. The <structfield>match.type</structfield> and
-<structfield>match.addr</structfield> or <structfield>match.name</structfield>
-fields select a chip on the TV
-card, the <structfield>reg</structfield> field specifies a register
-number and the <structfield>val</structfield> field the value to be
-written into the register.</para>
-
-    <para>To read a register applications must initialize the
-<structfield>match.type</structfield>,
-<structfield>match.addr</structfield> or <structfield>match.name</structfield> and
-<structfield>reg</structfield> fields, and call
-<constant>VIDIOC_DBG_G_REGISTER</constant> with a pointer to this
-structure. On success the driver stores the register value in the
-<structfield>val</structfield> field and the size (in bytes) of the
-value in <structfield>size</structfield>.</para>
-
-    <para>When <structfield>match.type</structfield> is
-<constant>V4L2_CHIP_MATCH_BRIDGE</constant>,
-<structfield>match.addr</structfield> selects the nth non-sub-device chip
-on the TV card.  The number zero always selects the host chip, &eg; the
-chip connected to the PCI or USB bus. You can find out which chips are
-present with the &VIDIOC-DBG-G-CHIP-INFO; ioctl.</para>
-
-    <para>When <structfield>match.type</structfield> is
-<constant>V4L2_CHIP_MATCH_SUBDEV</constant>,
-<structfield>match.addr</structfield> selects the nth sub-device.</para>
-
-    <para>These ioctls are optional, not all drivers may support them.
-However when a driver supports these ioctls it must also support
-&VIDIOC-DBG-G-CHIP-INFO;. Conversely it may support
-<constant>VIDIOC_DBG_G_CHIP_INFO</constant> but not these ioctls.</para>
-
-    <para><constant>VIDIOC_DBG_G_REGISTER</constant> and
-<constant>VIDIOC_DBG_S_REGISTER</constant> were introduced in Linux
-2.6.21, but their API was changed to the one described here in kernel 2.6.29.</para>

-    <para>These ioctls control an audio/video (usually MPEG-) encoder.

-try a command without actually executing it.</para>
-
-    <para>To send a command applications must initialize all fields of a
-    &v4l2-encoder-cmd; and call
-    <constant>VIDIOC_ENCODER_CMD</constant> or

-
-    <para>The <structfield>cmd</structfield> field must contain the

-encoding will continue until the end of the current <wordasword>Group
-Of Pictures</wordasword>, otherwise it will stop immediately.</para>
-
-    <para>A <function>read</function>() or &VIDIOC-STREAMON; call sends an implicit
-START command to the encoder if it has not been started yet. After a STOP command,
-<function>read</function>() calls will read the remaining data
-buffered by the driver. When the buffer is empty,
-<function>read</function>() will return zero and the next
-<function>read</function>() call will restart the encoder.</para>
-

-file descriptor sends an implicit immediate STOP to the encoder, and all buffered
-data is discarded.</para>

-	<para><emphasis role="bold">Discrete:</emphasis> The function
-returns success if the given index value (zero-based) is valid. The

-<constant>EINVAL</constant> is returned. The `v4l2_frmivalenum.type`
-field is set to `V4L2_FRMIVAL_TYPE_DISCRETE` by the driver. Of the
-union only the `discrete` member is valid.</para>

-<para>This ioctl is an extension to the <link linkend="mmap">memory
-mapping</link> I/O method, therefore it is available only for
-<constant>V4L2_MEMORY_MMAP</constant> buffers.  It can be used to export a
-buffer as a DMABUF file at any time after buffers have been allocated with the
-&VIDIOC-REQBUFS; ioctl.</para>
-
-<para> To export a buffer, applications fill &v4l2-exportbuffer;.  The
-<structfield>type</structfield> field is set to the same buffer type as was
-previously used with &v4l2-requestbuffers; <structfield>type</structfield>.
-Applications must also set the <structfield>index</structfield> field. Valid
-index numbers range from zero to the number of buffers allocated with
-&VIDIOC-REQBUFS; (&v4l2-requestbuffers; <structfield>count</structfield>)
-minus one.  For the multi-planar API, applications set the <structfield>plane</structfield>
-field to the index of the plane to be exported. Valid planes
-range from zero to the maximal number of valid planes for the currently active
-format. For the single-planar API, applications must set <structfield>plane</structfield>
-to zero.  Additional flags may be posted in the <structfield>flags</structfield>
-field.  Refer to a manual for open() for details.
-Currently only O_CLOEXEC, O_RDONLY, O_WRONLY, and O_RDWR are supported.  All
-other fields must be set to zero.
-In the case of multi-planar API, every plane is exported separately using
-multiple <constant>VIDIOC_EXPBUF</constant> calls.</para>
-
-<para>After calling <constant>VIDIOC_EXPBUF</constant> the <structfield>fd</structfield>
-field will be set by a driver.  This is a DMABUF file
-descriptor. The application may pass it to other DMABUF-aware devices. Refer to
-<link linkend="dmabuf">DMABUF importing</link> for details about importing
-DMABUF files into V4L2 nodes. It is recommended to close a DMABUF file when it
-is no longer used to allow the associated memory to be reclaimed.</para>

-of six. These formats can be optionally played at 1 / 1.001 speed to
-be compatible with 60 Hz based standards such as NTSC and PAL-M that use a framerate of
-29.97 frames per second. If the transmitter can't generate such frequencies, then the
-flag will also be cleared. This is a read-only flag, applications must not set this.
-	    </entry>
-	  </row>
-	  <row>
-	    <entry>V4L2_DV_FL_REDUCED_FPS</entry>
-	    <entry>CEA-861 specific: only valid for video transmitters, the flag is cleared
-by receivers. It is also only valid for formats with the V4L2_DV_FL_CAN_REDUCE_FPS flag
-set, for other formats the flag will be cleared by the driver.
-
-If the application sets this flag, then the pixelclock used to set up the transmitter is
-divided by 1.001 to make it compatible with NTSC framerates. If the transmitter
-can't generate such frequencies, then the flag will also be cleared.
-	    </entry>
-	  </row>
-	  <row>
-	    <entry>V4L2_DV_FL_HALF_LINE</entry>
-	    <entry>Specific to interlaced formats: if set, then the vertical frontporch
-of field 1 (aka the odd field) is really one half-line longer and the vertical backporch
-of field 2 (aka the even field) is really one half-line shorter, so each field has exactly
-the same number of half-lines. Whether half-lines can be detected or used depends on
-the hardware.
-	    </entry>
-	  </row>
-	  <row>
-	    <entry>V4L2_DV_FL_IS_CE_VIDEO</entry>
-	    <entry>If set, then this is a Consumer Electronics (CE) video format.
-Such formats differ from other formats (commonly called IT formats) in that if
-R'G'B' encoding is used then by default the R'G'B' values use limited range
-(i.e. 16-235) as opposed to full range (i.e. 0-255). All formats defined in CEA-861
-except for the 640x480p59.94 format are CE formats.

-    <para>These ioctls can be used to get or set an EDID associated with an input
-    from a receiver or an output of a transmitter device. They can be
-    used with subdevice nodes (/dev/v4l-subdevX) or with video nodes (/dev/videoX).</para>
-
-    <para>When used with video nodes the <structfield>pad</structfield> field represents the
-    input (for video capture devices) or output (for video output devices) index as
-    is returned by &VIDIOC-ENUMINPUT; and &VIDIOC-ENUMOUTPUT; respectively. When used
-    with subdevice nodes the <structfield>pad</structfield> field represents the
-    input or output pad of the subdevice. If there is no EDID support for the given
-    <structfield>pad</structfield> value, then the &EINVAL; will be returned.</para>
-
-    <para>To get the EDID data the application has to fill in the <structfield>pad</structfield>,
-    <structfield>start_block</structfield>, <structfield>blocks</structfield> and <structfield>edid</structfield>
-    fields, zero the <structfield>reserved</structfield> array and call
-    <constant>VIDIOC_G_EDID</constant>. The current EDID from block
-    <structfield>start_block</structfield> and of size <structfield>blocks</structfield>
-    will be placed in the memory <structfield>edid</structfield> points to. The <structfield>edid</structfield>
-    pointer must point to memory at least <structfield>blocks</structfield>&nbsp;*&nbsp;128 bytes
-    large (the size of one block is 128 bytes).</para>
-
-    <para>If there are fewer blocks than specified, then the driver will set <structfield>blocks</structfield>
-    to the actual number of blocks. If there are no EDID blocks available at all, then the error code
-    ENODATA is set.</para>
-
-    <para>If blocks have to be retrieved from the sink, then this call will block until they
-    have been read.</para>
-
-    <para>If <structfield>start_block</structfield> and <structfield>blocks</structfield> are
-    both set to 0 when <constant>VIDIOC_G_EDID</constant> is called, then the driver will
-    set <structfield>blocks</structfield> to the total number of available EDID blocks
-    and it will return 0 without copying any data. This is an easy way to discover how many
-    EDID blocks there are. Note that if there are no EDID blocks available at all, then
-    the driver will set <structfield>blocks</structfield> to 0 and it returns 0.</para>
-
-    <para>To set the EDID blocks of a receiver the application has to fill in the <structfield>pad</structfield>,
-    <structfield>blocks</structfield> and <structfield>edid</structfield> fields, set
-    <structfield>start_block</structfield> to 0 and zero the <structfield>reserved</structfield> array.
-    It is not possible to set part of an EDID,
-    it is always all or nothing. Setting the EDID data is only valid for receivers as it makes
-    no sense for a transmitter.</para>
-
-    <para>The driver assumes that the full EDID is passed in. If there are more EDID blocks than
-    the hardware can handle then the EDID is not written, but instead the error code E2BIG is set
-    and <structfield>blocks</structfield> is set to the maximum that the hardware supports.
-    If <structfield>start_block</structfield> is any
-    value other than 0 then the error code EINVAL is set.</para>
-
-    <para>To disable an EDID you set <structfield>blocks</structfield> to 0. Depending on the
-    hardware this will drive the hotplug pin low and/or block the source from reading the EDID
-    data in some way. In any case, the end result is the same: the EDID is no longer available.

-
-    <para>These ioctls allow the caller to get or set multiple
-controls atomically. Control IDs are grouped into control classes (see
-<xref linkend="ctrl-class" />) and all controls in the control array
-must belong to the same control class.</para>
-
-    <para>Applications must always fill in the
-<structfield>count</structfield>,
-<structfield>which</structfield>,
-<structfield>controls</structfield> and
-<structfield>reserved</structfield> fields of &v4l2-ext-controls;, and
-initialize the &v4l2-ext-control; array pointed to by the
-<structfield>controls</structfield> fields.</para>
-
-    <para>To get the current value of a set of controls applications
-initialize the <structfield>id</structfield>,
-<structfield>size</structfield> and <structfield>reserved2</structfield> fields
-of each &v4l2-ext-control; and call the
-<constant>VIDIOC_G_EXT_CTRLS</constant> ioctl. String controls controls
-must also set the <structfield>string</structfield> field. Controls
-of compound types (<constant>V4L2_CTRL_FLAG_HAS_PAYLOAD</constant> is set)
-must set the <structfield>ptr</structfield> field.</para>
-
-    <para>If the <structfield>size</structfield> is too small to
-receive the control result (only relevant for pointer-type controls
-like strings), then the driver will set <structfield>size</structfield>
-to a valid value and return an &ENOSPC;. You should re-allocate the
-memory to this new size and try again. For the string type it is possible that
-the same issue occurs again if the string has grown in the meantime. It is
-recommended to call &VIDIOC-QUERYCTRL; first and use
-<structfield>maximum</structfield>+1 as the new <structfield>size</structfield>
-value. It is guaranteed that that is sufficient memory.
-</para>
-
-    <para>N-dimensional arrays are set and retrieved row-by-row. You cannot set a partial
-array, all elements have to be set or retrieved. The total size is calculated
-as <structfield>elems</structfield> * <structfield>elem_size</structfield>.
-These values can be obtained by calling &VIDIOC-QUERY-EXT-CTRL;.</para>
-
-    <para>To change the value of a set of controls applications
-initialize the <structfield>id</structfield>, <structfield>size</structfield>,
-<structfield>reserved2</structfield> and
-<structfield>value/value64/string/ptr</structfield> fields of each &v4l2-ext-control; and
-call the <constant>VIDIOC_S_EXT_CTRLS</constant> ioctl. The controls
-will only be set if <emphasis>all</emphasis> control values are
-valid.</para>
-
-    <para>To check if a set of controls have correct values applications
-initialize the <structfield>id</structfield>, <structfield>size</structfield>,
-<structfield>reserved2</structfield> and
-<structfield>value/value64/string/ptr</structfield> fields of each &v4l2-ext-control; and
-call the <constant>VIDIOC_TRY_EXT_CTRLS</constant> ioctl. It is up to
-the driver whether wrong values are automatically adjusted to a valid
-value or if an error is returned.</para>
-
-    <para>When the <structfield>id</structfield> or
-<structfield>which</structfield> is invalid drivers return an
-&EINVAL;. When the value is out of bounds drivers can choose to take
-the closest valid value or return an &ERANGE;, whatever seems more
-appropriate. In the first case the new value is set in
-&v4l2-ext-control;. If the new control value is inappropriate (e.g. the
-given menu index is not supported by the menu control), then this will
-also result in an &EINVAL; error.</para>
-
-    <para>The driver will only set/get these controls if all control
-values are correct. This prevents the situation where only some of the
-controls were set/get. Only low-level errors (&eg; a failed i2c
-command) can still cause this situation.</para>

-The value is undefined if the ioctl returned 0 (success).</para>
-
-<para>Before controls are read from/written to hardware a validation step
-takes place: this checks if all controls in the list are valid controls,
-if no attempt is made to write to a read-only control or read from a write-only
-control, and any other up-front checks that can be done without accessing the
-hardware. The exact validations done during this step are driver dependent
-since some checks might require hardware access for some devices, thus making
-it impossible to do those checks up-front. However, drivers should make a
-best-effort to do as many up-front checks as possible.</para>
-
-<para>This check is done to avoid leaving the hardware in an inconsistent state due
-to easy-to-avoid problems. But it leads to another problem: the application needs to
-know whether an error came from the validation step (meaning that the hardware
-was not touched) or from an error during the actual reading from/writing to hardware.</para>
-
-<para>The, in hindsight quite poor, solution for that is to set <structfield>error_idx</structfield>
-to <structfield>count</structfield> if the validation failed. This has the
-unfortunate side-effect that it is not possible to see which control failed the
-validation. If the validation was successful and the error happened while
-accessing the hardware, then <structfield>error_idx</structfield> is less than
-<structfield>count</structfield> and only the controls up to
-<structfield>error_idx-1</structfield> were read or written correctly, and the
-state of the remaining controls is undefined.</para>
-
-<para>Since <constant>VIDIOC_TRY_EXT_CTRLS</constant> does not access hardware
-there is also no need to handle the validation step in this special way,
-so <structfield>error_idx</structfield> will just be set to the control that
-failed the validation step instead of to <structfield>count</structfield>.
-This means that if <constant>VIDIOC_S_EXT_CTRLS</constant> fails with
-<structfield>error_idx</structfield> set to <structfield>count</structfield>,
-then you can call <constant>VIDIOC_TRY_EXT_CTRLS</constant> to try to discover
-the actual control that failed the validation step. Unfortunately, there
-is no <constant>TRY</constant> equivalent for <constant>VIDIOC_G_EXT_CTRLS</constant>.

-
-    <para>Applications can use the <constant>VIDIOC_G_FBUF</constant> and
-<constant>VIDIOC_S_FBUF</constant> ioctl to get and set the
-framebuffer parameters for a <link linkend="overlay">Video
-Overlay</link> or <link linkend="osd">Video Output Overlay</link>
-(OSD). The type of overlay is implied by the device type (capture or
-output device) and can be determined with the &VIDIOC-QUERYCAP; ioctl.
-One <filename>/dev/videoN</filename> device must not support both
-kinds of overlay.</para>
-
-    <para>The V4L2 API distinguishes destructive and non-destructive
-overlays. A destructive overlay copies captured video images into the
-video memory of a graphics card. A non-destructive overlay blends
-video images into a VGA signal or graphics into a video signal.
-<wordasword>Video Output Overlays</wordasword> are always
-non-destructive.</para>
-
-    <para>To get the current parameters applications call the
-<constant>VIDIOC_G_FBUF</constant> ioctl with a pointer to a
-<structname>v4l2_framebuffer</structname> structure. The driver fills
-all fields of the structure or returns an &EINVAL; when overlays are
-not supported.</para>
-
-    <para>To set the parameters for a <wordasword>Video Output
-Overlay</wordasword>, applications must initialize the
-<structfield>flags</structfield> field of a struct
-<structname>v4l2_framebuffer</structname>. Since the framebuffer is
-implemented on the TV card all other parameters are determined by the
-driver. When an application calls <constant>VIDIOC_S_FBUF</constant>
-with a pointer to this structure, the driver prepares for the overlay
-and returns the framebuffer parameters as
-<constant>VIDIOC_G_FBUF</constant> does, or it returns an error
-code.</para>
-
-    <para>To set the parameters for a <wordasword>non-destructive
-Video Overlay</wordasword>, applications must initialize the
-<structfield>flags</structfield> field, the
-<structfield>fmt</structfield> substructure, and call
-<constant>VIDIOC_S_FBUF</constant>. Again the driver prepares for the
-overlay and returns the framebuffer parameters as
-<constant>VIDIOC_G_FBUF</constant> does, or it returns an error
-code.</para>
-
-    <para>For a <wordasword>destructive Video Overlay</wordasword>
-applications must additionally provide a
-<structfield>base</structfield> address. Setting up a DMA to a
-random memory location can jeopardize the system security, its
-stability or even damage the hardware, therefore only the superuser
-can set the parameters for a destructive video overlay.</para>

-
-    <para>These ioctls are used to negotiate the format of data
-(typically image format) exchanged between driver and
-application.</para>
-
-    <para>To query the current parameters applications set the
-<structfield>type</structfield> field of a struct
-<structname>v4l2_format</structname> to the respective buffer (stream)
-type. For example video capture devices use
-<constant>V4L2_BUF_TYPE_VIDEO_CAPTURE</constant> or
-<constant>V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE</constant>. When the application
-calls the <constant>VIDIOC_G_FMT</constant> ioctl with a pointer to
-this structure the driver fills the respective member of the
-<structfield>fmt</structfield> union. In case of video capture devices
-that is either the &v4l2-pix-format; <structfield>pix</structfield> or
-the &v4l2-pix-format-mplane; <structfield>pix_mp</structfield> member.
-When the requested buffer type is not supported drivers return an
-&EINVAL;.</para>
-
-    <para>To change the current format parameters applications
-initialize the <structfield>type</structfield> field and all
-fields of the respective <structfield>fmt</structfield>
-union member. For details see the documentation of the various devices
-types in <xref linkend="devices" />. Good practice is to query the
-current parameters first, and to
-modify only those parameters not suitable for the application. When
-the application calls the <constant>VIDIOC_S_FMT</constant> ioctl
-with a pointer to a <structname>v4l2_format</structname> structure
-the driver checks
-and adjusts the parameters against hardware abilities. Drivers
-should not return an error code unless the <structfield>type</structfield> field is invalid, this is
-a mechanism to fathom device capabilities and to approach parameters
-acceptable for both the application and driver. On success the driver
-may program the hardware, allocate resources and generally prepare for
-data exchange.
-Finally the <constant>VIDIOC_S_FMT</constant> ioctl returns the
-current format parameters as <constant>VIDIOC_G_FMT</constant> does.
-Very simple, inflexible devices may even ignore all input and always
-return the default parameters. However all V4L2 devices exchanging
-data with the application must implement the
-<constant>VIDIOC_G_FMT</constant> and
-<constant>VIDIOC_S_FMT</constant> ioctl. When the requested buffer
-type is not supported drivers return an &EINVAL; on a
-<constant>VIDIOC_S_FMT</constant> attempt. When I/O is already in
-progress or the resource is not available for other reasons drivers
-return the &EBUSY;.</para>
-
-    <para>The <constant>VIDIOC_TRY_FMT</constant> ioctl is equivalent
-to <constant>VIDIOC_S_FMT</constant> with one exception: it does not
-change driver state. It can also be called at any time, never
-returning <errorcode>EBUSY</errorcode>. This function is provided to
-negotiate parameters, to learn about hardware limitations, without
-disabling I/O or possibly time consuming hardware preparations.
-Although strongly recommended drivers are not required to implement
-this ioctl.</para>
-
-    <para>The format as returned by <constant>VIDIOC_TRY_FMT</constant>
-must be identical to what <constant>VIDIOC_S_FMT</constant> returns for
-the same input or output.</para>

-
-    <para>Applications call the <constant>VIDIOC_QBUF</constant> ioctl
-to enqueue an empty (capturing) or filled (output) buffer in the
-driver's incoming queue. The semantics depend on the selected I/O
-method.</para>
-
-    <para>To enqueue a buffer applications set the <structfield>type</structfield>
-field of a &v4l2-buffer; to the same buffer type as was previously used
-with &v4l2-format; <structfield>type</structfield> and &v4l2-requestbuffers;
-<structfield>type</structfield>. Applications must also set the
-<structfield>index</structfield> field. Valid index numbers range from
-zero to the number of buffers allocated with &VIDIOC-REQBUFS;
-(&v4l2-requestbuffers; <structfield>count</structfield>) minus one. The
-contents of the struct <structname>v4l2_buffer</structname> returned
-by a &VIDIOC-QUERYBUF; ioctl will do as well. When the buffer is
-intended for output (<structfield>type</structfield> is
-<constant>V4L2_BUF_TYPE_VIDEO_OUTPUT</constant>,
-<constant>V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE</constant>, or
-<constant>V4L2_BUF_TYPE_VBI_OUTPUT</constant>) applications must also
-initialize the <structfield>bytesused</structfield>,
-<structfield>field</structfield> and
-<structfield>timestamp</structfield> fields, see <xref
-linkend="buffer" /> for details.
-Applications must also set <structfield>flags</structfield> to 0.
-The <structfield>reserved2</structfield> and
-<structfield>reserved</structfield> fields must be set to 0. When using
-the <link linkend="planar-apis">multi-planar API</link>, the
-<structfield>m.planes</structfield> field must contain a userspace pointer
-to a filled-in array of &v4l2-plane; and the <structfield>length</structfield>
-field must be set to the number of elements in that array.
-</para>
-
-    <para>To enqueue a <link linkend="mmap">memory mapped</link>
-buffer applications set the <structfield>memory</structfield>
-field to <constant>V4L2_MEMORY_MMAP</constant>. When
-<constant>VIDIOC_QBUF</constant> is called with a pointer to this
-structure the driver sets the
-<constant>V4L2_BUF_FLAG_MAPPED</constant> and
-<constant>V4L2_BUF_FLAG_QUEUED</constant> flags and clears the
-<constant>V4L2_BUF_FLAG_DONE</constant> flag in the
-<structfield>flags</structfield> field, or it returns an
-&EINVAL;.</para>
-
-    <para>To enqueue a <link linkend="userp">user pointer</link>
-buffer applications set the <structfield>memory</structfield>
-field to <constant>V4L2_MEMORY_USERPTR</constant>, the
-<structfield>m.userptr</structfield> field to the address of the
-buffer and <structfield>length</structfield> to its size. When the multi-planar
-API is used, <structfield>m.userptr</structfield> and
-<structfield>length</structfield> members of the passed array of &v4l2-plane;
-have to be used instead. When <constant>VIDIOC_QBUF</constant> is called with
-a pointer to this structure the driver sets the
-<constant>V4L2_BUF_FLAG_QUEUED</constant> flag and clears the
-<constant>V4L2_BUF_FLAG_MAPPED</constant> and
-<constant>V4L2_BUF_FLAG_DONE</constant> flags in the
-<structfield>flags</structfield> field, or it returns an error code.
-This ioctl locks the memory pages of the buffer in physical memory,
-they cannot be swapped out to disk. Buffers remain locked until
-dequeued, until the &VIDIOC-STREAMOFF; or &VIDIOC-REQBUFS; ioctl is
-called, or until the device is closed.</para>
-
-    <para>To enqueue a <link linkend="dmabuf">DMABUF</link> buffer applications
-set the <structfield>memory</structfield> field to
-<constant>V4L2_MEMORY_DMABUF</constant> and the <structfield>m.fd</structfield>
-field to a file descriptor associated with a DMABUF buffer. When the
-multi-planar API is used the <structfield>m.fd</structfield> fields of the
-passed array of &v4l2-plane; have to be used instead. When
-<constant>VIDIOC_QBUF</constant> is called with a pointer to this structure the
-driver sets the <constant>V4L2_BUF_FLAG_QUEUED</constant> flag and clears the
-<constant>V4L2_BUF_FLAG_MAPPED</constant> and
-<constant>V4L2_BUF_FLAG_DONE</constant> flags in the
-<structfield>flags</structfield> field, or it returns an error code.  This
-ioctl locks the buffer. Locking a buffer means passing it to a driver for a
-hardware access (usually DMA).  If an application accesses (reads/writes) a
-locked buffer then the result is undefined.  Buffers remain locked until
-dequeued, until the &VIDIOC-STREAMOFF; or &VIDIOC-REQBUFS; ioctl is called, or
-until the device is closed.</para>
-
-    <para>Applications call the <constant>VIDIOC_DQBUF</constant>
-ioctl to dequeue a filled (capturing) or displayed (output) buffer
-from the driver's outgoing queue. They just set the
-<structfield>type</structfield>, <structfield>memory</structfield>
-and <structfield>reserved</structfield>
-fields of a &v4l2-buffer; as above, when <constant>VIDIOC_DQBUF</constant>
-is called with a pointer to this structure the driver fills the
-remaining fields or returns an error code. The driver may also set
-<constant>V4L2_BUF_FLAG_ERROR</constant> in the <structfield>flags</structfield>
-field. It indicates a non-critical (recoverable) streaming error. In such case
-the application may continue as normal, but should be aware that data in the

-    <para>The hardware may be able to detect the current DV timings
-automatically, similar to sensing the video standard. To do so, applications
-call <constant>VIDIOC_QUERY_DV_TIMINGS</constant> with a pointer to a
-&v4l2-dv-timings;. Once the hardware detects the timings, it will fill in the
-timings structure.</para>
-
-<para>Please note that drivers shall <emphasis>not</emphasis> switch timings automatically
-if new timings are detected. Instead, drivers should send the
-<constant>V4L2_EVENT_SOURCE_CHANGE</constant> event (if they support this) and expect
-that userspace will take action by calling <constant>VIDIOC_QUERY_DV_TIMINGS</constant>.
-The reason is that new timings usually mean different buffer sizes as well, and you
-cannot change buffer sizes on the fly. In general, applications that receive the
-Source Change event will have to call <constant>VIDIOC_QUERY_DV_TIMINGS</constant>,
-and if the detected timings are valid they will have to stop streaming, set the new
-timings, allocate new buffers and start streaming again.</para>
-
-<para>If the timings could not be detected because there was no signal, then
-<errorcode>ENOLINK</errorcode> is returned. If a signal was detected, but
-it was unstable and the receiver could not lock to the signal, then
-<errorcode>ENOLCK</errorcode> is returned. If the receiver could lock to the signal,
-but the format is unsupported (e.g. because the pixelclock is out of range
-of the hardware capabilities), then the driver fills in whatever timings it
-could find and returns <errorcode>ERANGE</errorcode>. In that case the application
-can call &VIDIOC-DV-TIMINGS-CAP; to compare the found timings with the hardware's
-capabilities in order to give more precise feedback to the user.

-    <para>To query the attributes of a control applications set the
-<structfield>id</structfield> field of a &v4l2-queryctrl; and call the
-<constant>VIDIOC_QUERYCTRL</constant> ioctl with a pointer to this
-structure. The driver fills the rest of the structure or returns an
-&EINVAL; when the <structfield>id</structfield> is invalid.</para>
-
-    <para>It is possible to enumerate controls by calling
-<constant>VIDIOC_QUERYCTRL</constant> with successive
-<structfield>id</structfield> values starting from
-<constant>V4L2_CID_BASE</constant> up to and exclusive
-<constant>V4L2_CID_LASTP1</constant>. Drivers may return
-<errorcode>EINVAL</errorcode> if a control in this range is not
-supported. Further applications can enumerate private controls, which
-are not defined in this specification, by starting at
-<constant>V4L2_CID_PRIVATE_BASE</constant> and incrementing
-<structfield>id</structfield> until the driver returns
-<errorcode>EINVAL</errorcode>.</para>
-
-    <para>In both cases, when the driver sets the
-<constant>V4L2_CTRL_FLAG_DISABLED</constant> flag in the

-	<para><constant>V4L2_CTRL_FLAG_DISABLED</constant> was
-intended for two purposes: Drivers can skip predefined controls not
-supported by the hardware (although returning EINVAL would do as
-well), or disable predefined and private controls after hardware
-detection without the trouble of reordering control arrays and indices
-(EINVAL cannot be used to skip private controls because it would
-prematurely end the enumeration).</para></footnote></para>
-
-    <para>When the application ORs <structfield>id</structfield> with
-<constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> the driver returns the
-next supported non-compound control, or <errorcode>EINVAL</errorcode>
-if there is none. In addition, the <constant>V4L2_CTRL_FLAG_NEXT_COMPOUND</constant>
-flag can be specified to enumerate all compound controls (i.e. controls
-with type &ge; <constant>V4L2_CTRL_COMPOUND_TYPES</constant> and/or array
-control, in other words controls that contain more than one value).
-Specify both <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> and
-<constant>V4L2_CTRL_FLAG_NEXT_COMPOUND</constant> in order to enumerate
-all controls, compound or not. Drivers which do not support these flags yet
-always return <errorcode>EINVAL</errorcode>.</para>
-
-    <para>The <constant>VIDIOC_QUERY_EXT_CTRL</constant> ioctl was
-introduced in order to better support controls that can use compound
-types, and to expose additional control information that cannot be
-returned in &v4l2-queryctrl; since that structure is full.</para>
-
-    <para><constant>VIDIOC_QUERY_EXT_CTRL</constant> is used in the
-same way as <constant>VIDIOC_QUERYCTRL</constant>, except that the
-<structfield>reserved</structfield> array must be zeroed as well.</para>
-
-    <para>Additional information is required for menu controls: the
-names of the menu items. To query them applications set the
-<structfield>id</structfield> and <structfield>index</structfield>
-fields of &v4l2-querymenu; and call the
-<constant>VIDIOC_QUERYMENU</constant> ioctl with a pointer to this
-structure. The driver fills the rest of the structure or returns an
-&EINVAL; when the <structfield>id</structfield> or
-<structfield>index</structfield> is invalid. Menu items are enumerated
-by calling <constant>VIDIOC_QUERYMENU</constant> with successive
-<structfield>index</structfield> values from &v4l2-queryctrl;
-<structfield>minimum</structfield> to
-<structfield>maximum</structfield>, inclusive. Note that it is possible
-for <constant>VIDIOC_QUERYMENU</constant> to return an &EINVAL; for some
-indices between <structfield>minimum</structfield> and <structfield>maximum</structfield>.
-In that case that particular menu item is not supported by this driver. Also note that
-the <structfield>minimum</structfield> value is not necessarily 0.</para>

-    <para>The hardware may be able to detect the current video
-standard automatically. To do so, applications call <constant>
-VIDIOC_QUERYSTD</constant> with a pointer to a &v4l2-std-id; type. The
-driver stores here a set of candidates, this can be a single flag or a
-set of supported standards if for example the hardware can only
-distinguish between 50 and 60 Hz systems. If no signal was detected,
-then the driver will return V4L2_STD_UNKNOWN. When detection is not
-possible or fails, the set must contain all standards supported by the
-current video input or output.</para>
-
-<para>Please note that drivers shall <emphasis>not</emphasis> switch the video standard
-automatically if a new video standard is detected. Instead, drivers should send the
-<constant>V4L2_EVENT_SOURCE_CHANGE</constant> event (if they support this) and expect
-that userspace will take action by calling <constant>VIDIOC_QUERYSTD</constant>.
-The reason is that a new video standard can mean different buffer sizes as well, and you
-cannot change buffer sizes on the fly. In general, applications that receive the
-Source Change event will have to call <constant>VIDIOC_QUERYSTD</constant>,
-and if the detected video standard is valid they will have to stop streaming, set the new
-standard, allocate new buffers and start streaming again.</para>

-<para>This ioctl is used to initiate <link linkend="mmap">memory mapped</link>,
-<link linkend="userp">user pointer</link> or <link
-linkend="dmabuf">DMABUF</link> based I/O.  Memory mapped buffers are located in
-device memory and must be allocated with this ioctl before they can be mapped
-into the application's address space. User buffers are allocated by
-applications themselves, and this ioctl is merely used to switch the driver
-into user pointer I/O mode and to setup some internal structures.
-Similarly, DMABUF buffers are allocated by applications through a device
-driver, and this ioctl only configures the driver into DMABUF I/O mode without
-performing any direct allocation.</para>
-
-    <para>To allocate device buffers applications initialize all fields of the
-<structname>v4l2_requestbuffers</structname> structure.  They set the
-<structfield>type</structfield> field to the respective stream or buffer type,
-the <structfield>count</structfield> field to the desired number of buffers,
-<structfield>memory</structfield> must be set to the requested I/O method and
-the <structfield>reserved</structfield> array must be zeroed. When the ioctl is
-called with a pointer to this structure the driver will attempt to allocate the
-requested number of buffers and it stores the actual number allocated in the
-<structfield>count</structfield> field. It can be smaller than the number
-requested, even zero, when the driver runs out of free memory. A larger number
-is also possible when the driver requires more buffers to function correctly.
-For example video output requires at least two buffers, one displayed and one
-filled by the application.</para>
-    <para>When the I/O method is not supported the ioctl
-returns an &EINVAL;.</para>
-
-    <para>Applications can call <constant>VIDIOC_REQBUFS</constant>
-again to change the number of buffers, however this cannot succeed
-when any buffers are still mapped. A <structfield>count</structfield>
-value of zero frees all buffers, after aborting or finishing any DMA
-in progress, an implicit &VIDIOC-STREAMOFF;. <!-- mhs: I see no
-reason why munmap()ping one or even all buffers must imply
-streamoff.--></para>

-    <para>This ioctl allows applications to enumerate all frame sizes
-    supported by a sub-device on the given pad for the given media bus format.
-    Supported formats can be retrieved with the &VIDIOC-SUBDEV-ENUM-MBUS-CODE;
-    ioctl.</para>
-
-    <para>To enumerate frame sizes applications initialize the
-    <structfield>pad</structfield>, <structfield>which</structfield> ,
-    <structfield>code</structfield> and <structfield>index</structfield>
-    fields of the &v4l2-subdev-mbus-code-enum; and call the
-    <constant>VIDIOC_SUBDEV_ENUM_FRAME_SIZE</constant> ioctl with a pointer to
-    the structure. Drivers fill the minimum and maximum frame sizes or return
-    an &EINVAL; if one of the input parameters is invalid.</para>
-
-    <para>Sub-devices that only support discrete frame sizes (such as most
-    sensors) will return one or more frame sizes with identical minimum and
-    maximum values.</para>
-
-    <para>Not all possible sizes in given [minimum, maximum] ranges need to be
-    supported. For instance, a scaler that uses a fixed-point scaling ratio
-    might not be able to produce every frame size between the minimum and
-    maximum values. Applications must use the &VIDIOC-SUBDEV-S-FMT; ioctl to
-    try the sub-device for an exact supported frame size.</para>
-
-    <para>Available frame sizes may depend on the current 'try' formats at other
-    pads of the sub-device, as well as on the current active links and the
-    current values of V4L2 controls. See &VIDIOC-SUBDEV-G-FMT; for more

-    <para>These ioctls are used to negotiate the frame format at specific
-    subdev pads in the image pipeline.</para>
-
-    <para>To retrieve the current format applications set the
-    <structfield>pad</structfield> field of a &v4l2-subdev-format; to the
-    desired pad number as reported by the media API and the
-    <structfield>which</structfield> field to
-    <constant>V4L2_SUBDEV_FORMAT_ACTIVE</constant>. When they call the
-    <constant>VIDIOC_SUBDEV_G_FMT</constant> ioctl with a pointer to this
-    structure the driver fills the members of the <structfield>format</structfield>
-    field.</para>
-
-    <para>To change the current format applications set both the
-    <structfield>pad</structfield> and <structfield>which</structfield> fields
-    and all members of the <structfield>format</structfield> field. When they
-    call the <constant>VIDIOC_SUBDEV_S_FMT</constant> ioctl with a pointer to this
-    structure the driver verifies the requested format, adjusts it based on the
-    hardware capabilities and configures the device. Upon return the
-    &v4l2-subdev-format; contains the current format as would be returned by a
-    <constant>VIDIOC_SUBDEV_G_FMT</constant> call.</para>
-
-    <para>Applications can query the device capabilities by setting the
-    <structfield>which</structfield> to
-    <constant>V4L2_SUBDEV_FORMAT_TRY</constant>. When set, 'try' formats are not
-    applied to the device by the driver, but are changed exactly as active
-    formats and stored in the sub-device file handle. Two applications querying
-    the same sub-device would thus not interact with each other.</para>
-
-    <para>For instance, to try a format at the output pad of a sub-device,
-    applications would first set the try format at the sub-device input with the
-    <constant>VIDIOC_SUBDEV_S_FMT</constant> ioctl. They would then either
-    retrieve the default format at the output pad with the
-    <constant>VIDIOC_SUBDEV_G_FMT</constant> ioctl, or set the desired output
-    pad format with the <constant>VIDIOC_SUBDEV_S_FMT</constant> ioctl and check
-    the returned value.</para>
-
-    <para>Try formats do not depend on active formats, but can depend on the
-    current links configuration or sub-device controls value. For instance, a
-    low-pass noise filter might crop pixels at the frame boundaries, modifying
-    its output frame size.</para>
-
-    <para>Drivers must not return an error solely because the requested format
-    doesn't match the device capabilities. They must instead modify the format
-    to match what the hardware can provide. The modified format should be as
-    close as possible to the original request.</para>

-	    <entry><para>If set, then events directly caused by an ioctl will also be sent to
-		the filehandle that called that ioctl. For example, changing a control using
-		&VIDIOC-S-CTRL; will cause a V4L2_EVENT_CTRL to be sent back to that same
-		filehandle. Normally such events are suppressed to prevent feedback loops
-		where an application changes a control to a one value and then another, and
-		then receives an event telling it that that control has changed to the first
-		value.</para>
-
-		<para>Since it can't tell whether that event was caused by another application
-		or by the &VIDIOC-S-CTRL; call it is hard to decide whether to set the
-		control to the value in the event, or ignore it.</para>
-
-		<para>Think carefully when you set this flag so you won't get into situations
-		like that.</para>

-* Broadcom SATA3 AHCI Controller for STB
-
-SATA nodes are defined to describe on-chip Serial ATA controllers.
-Each SATA controller should have its own node.
-
-Required properties:
-- compatible         : should be one or more of
-                       "brcm,bcm7425-ahci"
-                       "brcm,bcm7445-ahci"
-                       "brcm,sata3-ahci"
-- reg                : register mappings for AHCI and SATA_TOP_CTRL
-- reg-names          : "ahci" and "top-ctrl"
-- interrupts         : interrupt mapping for SATA IRQ
-
-Also see ahci-platform.txt.
-
-Example:
-
-	sata@f045a000 {
-		compatible = "brcm,bcm7445-ahci", "brcm,sata3-ahci";
-		reg = <0xf045a000 0xa9c>, <0xf0458040 0x24>;
-		reg-names = "ahci", "top-ctrl";
-		interrupts = <0 30 0>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-
-		sata0: sata-port@0 {
-			reg = <0>;
-			phys = <&sata_phy 0>;

-* Freescale Communications Processor Module
-
-NOTE: This is an interim binding, and will likely change slightly,
-as more devices are supported.  The QE bindings especially are
-incomplete.
-
-* Root CPM node
-
-Properties:
-- compatible : "fsl,cpm1", "fsl,cpm2", or "fsl,qe".
-- reg : A 48-byte region beginning with CPCR.
-
-Example:
-     cpm@119c0 {
-	#address-cells = <1>;
-	#size-cells = <1>;
-	#interrupt-cells = <2>;
-	compatible = "fsl,mpc8272-cpm", "fsl,cpm2";
-	reg = <119c0 30>;
-     }
-
-* Properties common to multiple CPM/QE devices
-
-- fsl,cpm-command : This value is ORed with the opcode and command flag
-                    to specify the device on which a CPM command operates.
-
-- fsl,cpm-brg : Indicates which baud rate generator the device
-                is associated with.  If absent, an unused BRG
-                should be dynamically allocated.  If zero, the
-                device uses an external clock rather than a BRG.
-
-- reg : Unless otherwise specified, the first resource represents the
-        scc/fcc/ucc registers, and the second represents the device's
-        parameter RAM region (if it has one).
-
-* Multi-User RAM (MURAM)
-
-The multi-user/dual-ported RAM is expressed as a bus under the CPM node.
-
-Ranges must be set up subject to the following restrictions:
-
-- Children's reg nodes must be offsets from the start of all muram, even
-  if the user-data area does not begin at zero.
-- If multiple range entries are used, the difference between the parent
-  address and the child address must be the same in all, so that a single
-  mapping can cover them all while maintaining the ability to determine
-  CPM-side offsets with pointer subtraction.  It is recommended that
-  multiple range entries not be used.
-- A child address of zero must be translatable, even if no reg resources
-  contain it.
-
-A child "data" node must exist, compatible with "fsl,cpm-muram-data", to
-indicate the portion of muram that is usable by the OS for arbitrary
-purposes.  The data node may have an arbitrary number of reg resources,
-all of which contribute to the allocatable muram pool.
-
-Example, based on mpc8272:
-	muram@0 {
-		#address-cells = <1>;
-		#size-cells = <1>;
-		ranges = <0 0 10000>;
-
-		data@0 {
-			compatible = "fsl,cpm-muram-data";
-			reg = <0 2000 9800 800>;

-  (typically 0x8afc 0x2).
-- #address-cells : Should be one. The cell is the i2c device address with

-- #size-cells : Should be zero.
-- clock-frequency : Can be used to set the i2c clock frequency. If
-  unspecified, a default frequency of 60kHz is being used.
-The following two properties are deprecated. They are only used by legacy
-i2c drivers to find the bus to probe:
-- linux,i2c-index : Can be used to hard code an i2c bus number. By default,
-  the bus number is dynamically assigned by the i2c core.
-- linux,i2c-class : Can be used to override the i2c class. The class is used
-  by legacy i2c device drivers to find a bus in a specific context like
-  system management, video or sound. By default, I2C_CLASS_HWMON (1) is
-  being used. The definition of the classes can be found in

-* Freescale QUICC Engine module (QE)
-This represents qe module that is installed on PowerQUICC II Pro.
-
-NOTE:  This is an interim binding; it should be updated to fit
-in with the CPM binding later in this document.
-
-Basically, it is a bus of devices, that could act more or less
-as a complete entity (UCC, USB etc ). All of them should be siblings on
-the "root" qe node, using the common properties from there.
-The description below applies to the qe of MPC8360 and
-more nodes and properties would be extended in the future.
-
-i) Root QE device
-
-Required properties:
-- compatible : should be "fsl,qe";
-- model : precise model of the QE, Can be "QE", "CPM", or "CPM2"
-- reg : offset and length of the device registers.
-- bus-frequency : the clock frequency for QUICC Engine.
-- fsl,qe-num-riscs: define how many RISC engines the QE has.
-- fsl,qe-num-snums: define how many serial number(SNUM) the QE can use for the
-  threads.
-
-Optional properties:
-- fsl,firmware-phandle:
-    Usage: required only if there is no fsl,qe-firmware child node
-    Value type: <phandle>
-    Definition: Points to a firmware node (see "QE Firmware Node" below)
-        that contains the firmware that should be uploaded for this QE.
-        The compatible property for the firmware node should say,
-        "fsl,qe-firmware".
-
-Recommended properties
-- brg-frequency : the internal clock source frequency for baud-rate
-  generators in Hz.
-
-Example:
-     qe@e0100000 {
-	#address-cells = <1>;
-	#size-cells = <1>;
-	#interrupt-cells = <2>;
-	compatible = "fsl,qe";
-	ranges = <0 e0100000 00100000>;
-	reg = <e0100000 480>;
-	brg-frequency = <0>;
-	bus-frequency = <179A7B00>;
-     }
-
-* Multi-User RAM (MURAM)
-
-Required properties:
-- compatible : should be "fsl,qe-muram", "fsl,cpm-muram".
-- mode : the could be "host" or "slave".
-- ranges : Should be defined as specified in 1) to describe the
-   translation of MURAM addresses.
-- data-only : sub-node which defines the address area under MURAM
-   bus that can be allocated as data/parameter
-
-Example:
-
-     muram@10000 {
-	compatible = "fsl,qe-muram", "fsl,cpm-muram";
-	ranges = <0 00010000 0000c000>;
-
-	data-only@0{
-		compatible = "fsl,qe-muram-data",
-			     "fsl,cpm-muram-data";
-		reg = <0 c000>;
-	};
-     };
-
-* QE Firmware Node
-
-This node defines a firmware binary that is embedded in the device tree, for
-the purpose of passing the firmware from bootloader to the kernel, or from
-the hypervisor to the guest.
-
-The firmware node itself contains the firmware binary contents, a compatible
-property, and any firmware-specific properties.  The node should be placed
-inside a QE node that needs it.  Doing so eliminates the need for a
-fsl,firmware-phandle property.  Other QE nodes that need the same firmware
-should define an fsl,firmware-phandle property that points to the firmware node
-in the first QE node.
-
-The fsl,firmware property can be specified in the DTS (possibly using incbin)
-or can be inserted by the boot loader at boot time.
-
-Required properties:
-  - compatible

-* Uploaded QE firmware
-
-      If a new firmware has been uploaded to the QE (usually by the
-      boot loader), then a 'firmware' child node should be added to the QE
-      node.  This node provides information on the uploaded firmware that
-      device drivers may need.
-
-      Required properties:
-      - id: The string name of the firmware.  This is taken from the 'id'
-            member of the qe_firmware structure of the uploaded firmware.
-            Device drivers can search this string to determine if the
-            firmware they want is already present.
-      - extended-modes: The Extended Modes bitfield, taken from the
-		   firmware binary.  It is a 64-bit number represented
-		   as an array of two 32-bit numbers.
-      - virtual-traps: The virtual traps, taken from the firmware binary.
-		  It is an array of 8 32-bit numbers.
-
-Example:
-	firmware {
-		id = "Soft-UART";
-		extended-modes = <0 0>;
-		virtual-traps = <0 0 0 0 0 0 0 0>;

-* Parallel I/O Ports
-
-This node configures Parallel I/O ports for CPUs with QE support.
-The node should reside in the "soc" node of the tree.  For each
-device that using parallel I/O ports, a child node should be created.
-See the definition of the Pin configuration nodes below for more
-information.
-
-Required properties:
-- device_type : should be "par_io".
-- reg : offset to the register set and its length.
-- num-ports : number of Parallel I/O ports
-
-Example:
-par_io@1400 {
-	reg = <1400 100>;
-	#address-cells = <1>;
-	#size-cells = <0>;
-	device_type = "par_io";
-	num-ports = <7>;
-	ucc_pin@01 {
-		......
-	};
-
-Note that "par_io" nodes are obsolete, and should not be used for
-the new device trees. Instead, each Par I/O bank should be represented
-via its own gpio-controller node:
-
-Required properties:
-- #gpio-cells : should be "2".
-- compatible : should be "fsl,<chip>-qe-pario-bank",
-  "fsl,mpc8323-qe-pario-bank".
-- reg : offset to the register set and its length.
-- gpio-controller : node to identify gpio controllers.
-

-	qe_pio_a: gpio-controller@1400 {
-		#gpio-cells = <2>;
-		compatible = "fsl,mpc8360-qe-pario-bank",

-* Pin configuration nodes
-
-Required properties:
-- pio-map : array of pin configurations.  Each pin is defined by 6
-  integers.  The six numbers are respectively: port, pin, dir,
-  open_drain, assignment, has_irq.
-  - port : port number of the pin; 0-6 represent port A-G in UM.
-  - pin : pin number in the port.
-  - dir : direction of the pin, should encode as follows:
-
-     0 = The pin is disabled
-     1 = The pin is an output
-     2 = The pin is an input
-     3 = The pin is I/O
-
-  - open_drain : indicates the pin is normal or wired-OR:
-
-     0 = The pin is actively driven as an output
-     1 = The pin is an open-drain driver. As an output, the pin is
-         driven active-low, otherwise it is three-stated.
-
-  - assignment : function number of the pin according to the Pin Assignment
-    tables in User Manual.  Each pin can have up to 4 possible functions in
-    QE and two options for CPM.
-  - has_irq : indicates if the pin is used as source of external
-    interrupts.
-
-Example:
-     ucc_pin@01 {

-* UCC (Unified Communications Controllers)
-
-Required properties:

-  "bisync", "atm", or "serial".
-- compatible : could be "ucc_geth" or "fsl_atm" and so on.
-- cell-index : the ucc number(1-8), corresponding to UCCx in UM.
-- reg : Offset and length of the register set for the device
-- interrupts : <a b> where a is the interrupt number and b is a
-  field that represents an encoding of the sense and level
-  information for the interrupt.  This should be encoded based on
-  the information in section 2) depending on the type of interrupt
-  controller you have.
-- interrupt-parent : the phandle for the interrupt controller that
-  services interrupts for this device.
-- pio-handle : The phandle for the Parallel I/O port configuration.
-- port-number : for UART drivers, the port number to use, between 0 and 3.
-  This usually corresponds to the /dev/ttyQE device, e.g. <0> = /dev/ttyQE0.
-  The port number is added to the minor number of the device.  Unlike the
-  CPM UART driver, the port-number is required for the QE UART driver.
-- soft-uart : for UART drivers, if specified this means the QE UART device
-  driver should use "Soft-UART" mode, which is needed on some SOCs that have
-  broken UART hardware.  Soft-UART is provided via a microcode upload.
-- rx-clock-name: the UCC receive clock source
-  "none": clock source is disabled
-  "brg1" through "brg16": clock source is BRG1-BRG16, respectively

-  "none": clock source is disabled
-  "brg1" through "brg16": clock source is BRG1-BRG16, respectively
-  "clk1" through "clk24": clock source is CLK1-CLK24, respectively
-The following two properties are deprecated.  rx-clock has been replaced
-with rx-clock-name, and tx-clock has been replaced with tx-clock-name.
-Drivers that currently use the deprecated properties should continue to
-do so, in order to support older device trees, but they should be updated
-to check for the new properties first.
-- rx-clock : represents the UCC receive clock source.
-  0x00 : clock source is disabled;

-  0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
-- tx-clock: represents the UCC transmit clock source;
-  0x00 : clock source is disabled;
-  0x1~0x10 : clock source is BRG1~BRG16 respectively;
-  0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.

-Documentation for dvb-usb-framework module and its devices
-
-Idea behind the dvb-usb-framework
-=================================
-
-In March 2005 I got the new Twinhan USB2.0 DVB-T device. They provided specs and a firmware.
-
-Quite keen I wanted to put the driver (with some quirks of course) into dibusb.
-After reading some specs and doing some USB snooping, it realized, that the
-dibusb-driver would be a complete mess afterwards. So I decided to do it in a
-different way: With the help of a dvb-usb-framework.
-
-The framework provides generic functions (mostly kernel API calls), such as:
-
-- Transport Stream URB handling in conjunction with dvb-demux-feed-control
-  (bulk and isoc are supported)
-- registering the device for the DVB-API
-- registering an I2C-adapter if applicable
-- remote-control/input-device handling
-- firmware requesting and loading (currently just for the Cypress USB
-  controllers)
-- other functions/methods which can be shared by several drivers (such as
-  functions for bulk-control-commands)
-- TODO: a I2C-chunker. It creates device-specific chunks of register-accesses
-  depending on length of a register and the number of values that can be
-  multi-written and multi-read.
-
-The source code of the particular DVB USB devices does just the communication
-with the device via the bus. The connection between the DVB-API-functionality
-is done via callbacks, assigned in a static device-description (struct
-dvb_usb_device) each device-driver has to have.
-
-For an example have a look in drivers/media/usb/dvb-usb/vp7045*.
-
-Objective is to migrate all the usb-devices (dibusb, cinergyT2, maybe the
-ttusb; flexcop-usb already benefits from the generic flexcop-device) to use
-the dvb-usb-lib.
-
-TODO: dynamic enabling and disabling of the pid-filter in regard to number of
-feeds requested.
-
-Supported devices
-========================
-
-See the LinuxTV DVB Wiki at www.linuxtv.org for a complete list of
-cards/drivers/firmwares:

-  2004-06-06 - first TS received, but kernel oops :/
-  2004-05-14 - firmware loader is working
-  2004-05-11 - start writing the driver
-
-1. How to use?
-1.1. Firmware
-
-Most of the USB drivers need to download a firmware to the device before start
-working.
-
-Have a look at the Wikipage for the DVB-USB-drivers to find out, which firmware
-you need for your device:
-
-https://linuxtv.org/wiki/index.php/DVB_USB
-
-1.2. Compiling
-
-Since the driver is in the linux kernel, activating the driver in
-your favorite config-environment should sufficient. I recommend
-to compile the driver as module. Hotplug does the rest.
-
-If you use dvb-kernel enter the build-2.6 directory run 'make' and 'insmod.sh
-load' afterwards.
-
-1.3. Loading the drivers
-
-Hotplug is able to load the driver, when it is needed (because you plugged
-in the device).
-
-If you want to enable debug output, you have to load the driver manually and
-from within the dvb-kernel cvs repository.
-
-first have a look, which debug level are available:
-
-modinfo dvb-usb
-modinfo dvb-usb-vp7045
-etc.
-
-modprobe dvb-usb debug=<level>
-modprobe dvb-usb-vp7045 debug=<level>
-etc.
-
-should do the trick.
-
-When the driver is loaded successfully, the firmware file was in
-the right place and the device is connected, the "Power"-LED should be
-turned on.
-
-At this point you should be able to start a dvb-capable application. I'm use
-(t|s)zap, mplayer and dvbscan to test the basics. VDR-xine provides the
-long-term test scenario.
-
-2. Known problems and bugs
-
-- Don't remove the USB device while running an DVB application, your system
-  will go crazy or die most likely.
-
-2.1. Adding support for devices
-
-TODO
-
-2.2. USB1.1 Bandwidth limitation
-
-A lot of the currently supported devices are USB1.1 and thus they have a
-maximum bandwidth of about 5-6 MBit/s when connected to a USB2.0 hub.
-This is not enough for receiving the complete transport stream of a
-DVB-T channel (which is about 16 MBit/s). Normally this is not a
-problem, if you only want to watch TV (this does not apply for HDTV),
-but watching a channel while recording another channel on the same
-frequency simply does not work very well. This applies to all USB1.1
-DVB-T devices, not just the dvb-usb-devices)
-
-The bug, where the TS is distorted by a heavy usage of the device is gone
-definitely. All dvb-usb-devices I was using (Twinhan, Kworld, DiBcom) are
-working like charm now with VDR. Sometimes I even was able to record a channel
-and watch another one.
-
-2.3. Comments
-
-Patches, comments and suggestions are very very welcome.

-HOWTO: Get An Avermedia DVB-T working under Linux
-	   ______________________________________________
-
-   Table of Contents
-   Assumptions and Introduction
-   The Avermedia DVB-T
-   Getting the card going
-   Receiving DVB-T in Australia
-   Known Limitations
-   Further Update
-
-Assumptions and Introduction
-
-   It  is assumed that the reader understands the basic structure
-   of  the Linux Kernel DVB drivers and the general principles of
-   Digital TV.
-
-   One  significant difference between Digital TV and Analogue TV
-   that  the  unwary  (like  myself)  should  consider  is  that,
-   although  the  component  structure  of budget DVB-T cards are
-   substantially  similar  to Analogue TV cards, they function in
-   substantially different ways.
-
-   The  purpose  of  an  Analogue TV is to receive and display an
-   Analogue  Television  signal. An Analogue TV signal (otherwise
-   known  as  composite  video)  is  an  analogue  encoding  of a
-   sequence  of  image frames (25 per second) rasterised using an
-   interlacing   technique.   Interlacing  takes  two  fields  to
-   represent  one  frame.  Computers today are at their best when
-   dealing  with  digital  signals,  not  analogue  signals and a
-   composite  video signal is about as far removed from a digital
-   data stream as you can get. Therefore, an Analogue TV card for
-   a PC has the following purpose:
-
-     * Tune the receiver to receive a broadcast signal
-     * demodulate the broadcast signal
-     * demultiplex  the  analogue video signal and analogue audio
-       signal  (note some countries employ a digital audio signal
-       embedded  within the modulated composite analogue signal -
-       NICAM.)
-     * digitize  the analogue video signal and make the resulting
-       datastream available to the data bus.
-
-   The  digital  datastream from an Analogue TV card is generated
-   by  circuitry on the card and is often presented uncompressed.
-   For  a PAL TV signal encoded at a resolution of 768x576 24-bit
-   color pixels over 25 frames per second - a fair amount of data
-   is  generated and must be processed by the PC before it can be
-   displayed  on the video monitor screen. Some Analogue TV cards
-   for  PCs  have  onboard  MPEG2  encoders  which permit the raw
-   digital  data  stream  to be presented to the PC in an encoded
-   and  compressed  form  -  similar  to the form that is used in
-   Digital TV.
-
-   The  purpose of a simple budget digital TV card (DVB-T,C or S)
-   is to simply:
-
-     * Tune the received to receive a broadcast signal.
-     * Extract  the encoded digital datastream from the broadcast
-       signal.
-     * Make  the  encoded digital datastream (MPEG2) available to
-       the data bus.
-
-   The  significant  difference between the two is that the tuner
-   on  the analogue TV card spits out an Analogue signal, whereas
-   the  tuner  on  the  digital  TV  card  spits out a compressed
-   encoded   digital   datastream.   As  the  signal  is  already
-   digitised,  it  is  trivial  to pass this datastream to the PC
-   databus  with  minimal  additional processing and then extract
-   the  digital  video  and audio datastreams passing them to the
-   appropriate software or hardware for decoding and viewing.
-     _________________________________________________________
-
-The Avermedia DVB-T
-
-   The Avermedia DVB-T is a budget PCI DVB card. It has 3 inputs:
-
-     * RF Tuner Input
-     * Composite Video Input (RCA Jack)
-     * SVIDEO Input (Mini-DIN)
-
-   The  RF  Tuner  Input  is the input to the tuner module of the
-   card.  The  Tuner  is  otherwise known as the "Frontend" . The
-   Frontend of the Avermedia DVB-T is a Microtune 7202D. A timely
-   post  to  the  linux-dvb  mailing  list  ascertained  that the
-   Microtune  7202D  is  supported  by the sp887x driver which is
-   found in the dvb-hw CVS module.
-
-   The  DVB-T card is based around the BT878 chip which is a very
-   common multimedia bridge and often found on Analogue TV cards.
-   There is no on-board MPEG2 decoder, which means that all MPEG2
-   decoding  must  be done in software, or if you have one, on an
-   MPEG2 hardware decoding card or chipset.
-     _________________________________________________________
-
-Getting the card going
-
-   In order to fire up the card, it is necessary to load a number
-   of modules from the DVB driver set. Prior to this it will have
-   been  necessary to download these drivers from the linuxtv CVS
-   server and compile them successfully.
-
-   Depending on the card's feature set, the Device Driver API for
-   DVB under Linux will expose some of the following device files
-   in the /dev tree:
-
-     * /dev/dvb/adapter0/audio0
-     * /dev/dvb/adapter0/ca0
-     * /dev/dvb/adapter0/demux0
-     * /dev/dvb/adapter0/dvr0
-     * /dev/dvb/adapter0/frontend0
-     * /dev/dvb/adapter0/net0
-     * /dev/dvb/adapter0/osd0
-     * /dev/dvb/adapter0/video0
-
-   The  primary  device  nodes that we are interested in (at this
-   stage) for the Avermedia DVB-T are:
-
-     * /dev/dvb/adapter0/dvr0
-     * /dev/dvb/adapter0/frontend0
-
-   The dvr0 device node is used to read the MPEG2 Data Stream and
-   the frontend0 node is used to tune the frontend tuner module.
-
-   At  this  stage,  it  has  not  been  able  to  ascertain  the
-   functionality  of the remaining device nodes in respect of the
-   Avermedia  DVBT.  However,  full  functionality  in respect of
-   tuning,  receiving  and  supplying  the  MPEG2  data stream is
-   possible  with the currently available versions of the driver.
-   It  may be possible that additional functionality is available
-   from  the  card  (i.e.  viewing the additional analogue inputs
-   that  the card presents), but this has not been tested yet. If
-   I get around to this, I'll update the document with whatever I
-   find.
-
-   To  power  up  the  card,  load  the  following modules in the
-   following order:
-
-     * modprobe bttv (normally loaded automatically)
-     * modprobe dvb-bt8xx (or place dvb-bt8xx in /etc/modules)
-
-   Insertion  of  these  modules  into  the  running  kernel will
-   activate the appropriate DVB device nodes. It is then possible
-   to start accessing the card with utilities such as scan, tzap,
-   dvbstream etc.
-
-   The frontend module sp887x.o, requires an external   firmware.

-
-Receiving DVB-T in Australia
-
-   I  have  no  experience of DVB-T in other countries other than
-   Australia,  so  I will attempt to explain how it works here in
-   Melbourne  and how this affects the configuration of the DVB-T
-   card.
-
-   The  Digital  Broadcasting  Australia  website has a Reception
-   locatortool which provides information on transponder channels
-   and  frequencies.  My  local  transmitter  happens to be Mount
-   Dandenong.
-
-   The frequencies broadcast by Mount Dandenong are:
-
-   Table 1. Transponder Frequencies Mount Dandenong, Vic, Aus.
-   Broadcaster Channel Frequency
-   ABC         VHF 12  226.5 MHz
-   TEN         VHF 11  219.5 MHz
-   NINE        VHF 8   191.625 MHz
-   SEVEN       VHF 6   177.5 MHz
-   SBS         UHF 29  536.5 MHz
-
-   The Scan utility has a set of compiled-in defaults for various
-   countries and regions, but if they do not suit, or if you have
-   a pre-compiled scan binary, you can specify a data file on the
-   command  line which contains the transponder frequencies. Here
-   is a sample file for the above channel transponders:
-# Data file for DVB scan program
-#
-# C Frequency SymbolRate FEC QAM
-# S Frequency Polarisation SymbolRate FEC
-# T Frequency Bandwidth FEC FEC2 QAM Mode Guard Hier
-T 226500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-T 191625000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-T 219500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-T 177500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-T 536500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-
-   The   defaults   for   the  transponder  frequency  and  other
-   modulation parameters were obtained from www.dba.org.au.
-
-   When  Scan  runs, it will output channels.conf information for
-   any  channel's transponders which the card's frontend can lock
-   onto.  (i.e.  any  whose  signal  is  strong  enough  at  your
-   antenna).
-
-   Here's my channels.conf file for anyone who's interested:

-     _________________________________________________________
-
-Known Limitations
-
-   At  present  I can say with confidence that the frontend tunes
-   via /dev/dvb/adapter{x}/frontend0 and supplies an MPEG2 stream
-   via   /dev/dvb/adapter{x}/dvr0.   I   have   not   tested  the
-   functionality  of any other part of the card yet. I will do so
-   over time and update this document.
-
-   There  are some limitations in the i2c layer due to a returned
-   error message inconsistency. Although this generates errors in
-   dmesg  and  the  system logs, it does not appear to affect the
-   ability of the frontend to function correctly.
-     _________________________________________________________
-
-Further Update

-How to get the bt8xx cards working
-==================================
-
-1) General information
-======================
-
-This class of cards has a bt878a as the PCI interface, and require the bttv driver
-for accessing the i2c bus and the gpio pins of the bt8xx chipset.
-Please see Documentation/dvb/cards.txt => o Cards based on the Conexant Bt8xx PCI bridge:
-
-Compiling kernel please enable:
-a.)"Device drivers" => "Multimedia devices" => "Video For Linux" => "Enable Video for Linux API 1 (DEPRECATED)"
-b.)"Device drivers" => "Multimedia devices" => "Video For Linux" => "Video Capture Adapters" => "BT848 Video For Linux"
-c.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices" => "DVB for Linux" "DVB Core Support" "Bt8xx based PCI Cards"
-
-Please use the following options with care as deselection of drivers which are in fact necessary
-may result in DVB devices that cannot be tuned due to lack of driver support:
-You can save RAM by deselecting every frontend module that your DVB card does not need.
-
-First please remove the static dependency of DVB card drivers on all frontend modules for all possible card variants by enabling:
-d.) "Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
- => "DVB for Linux" "DVB Core Support" "Load and attach frontend modules as needed"
-
-If you know the frontend driver that your card needs please enable:
-e.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
- => "DVB for Linux" "DVB Core Support" "Customise DVB Frontends" => "Customise the frontend modules to build"
- Then please select your card-specific frontend module.
-
-2) Loading Modules
-==================
-
-Regular case: If the bttv driver detects a bt8xx-based DVB card, all frontend and backend modules will be loaded automatically.
-Exceptions are:
-- Old TwinHan DST cards or clones with or without CA slot and not containing an Eeprom.
-People running udev please see Documentation/dvb/udev.txt.
-
-In the following cases overriding the PCI type detection for dvb-bt8xx might be necessary:
-
-2a) Running TwinHan and Clones
-------------------------------
-
-	$ modprobe bttv card=113
-	$ modprobe dst
-
-Useful parameters for verbosity level and debugging the dst module:
-
-verbose=0:		messages are disabled
-	1:		only error messages are displayed
-	2:		notifications are displayed
-	3:		other useful messages are displayed
-	4:		debug setting
-dst_addons=0:		card is a free to air (FTA) card only
-	   0x20:	card has a conditional access slot for scrambled channels
-
-The autodetected values are determined by the cards' "response string".
-In your logs see f. ex.: dst_get_device_id: Recognize [DSTMCI].
-For bug reports please send in a complete log with verbose=4 activated.
-Please also see Documentation/dvb/ci.txt.
-
-2b) Running multiple cards
---------------------------
-
-Examples of card ID's:
-
-Pinnacle PCTV Sat:		 94
-Nebula Electronics Digi TV:	104
-pcHDTV HD-2000 TV:		112
-Twinhan DST and clones:		113
-Avermedia AverTV DVB-T 771:	123
-Avermedia AverTV DVB-T 761:	124
-DViCO FusionHDTV DVB-T Lite:	128
-DViCO FusionHDTV 5 Lite:	135
-
-Notice: The order of the card ID should be uprising:
-Example:
-	$ modprobe bttv card=113 card=135
-
-For a full list of card ID's please see Documentation/video4linux/CARDLIST.bttv.
-In case of further problems please subscribe and send questions to the mailing list: linux-dvb@linuxtv.org.
-
-2c) Probing the cards with broken PCI subsystem ID
---------------------------------------------------
-There are some TwinHan cards that the EEPROM has become corrupted for some
-reason. The cards do not have correct PCI subsystem ID. But we can force
-probing the cards with broken PCI subsystem ID
-
-	$ echo 109e 0878 $subvendor $subdevice > \
-		/sys/bus/pci/drivers/bt878/new_id
-
-109e: PCI_VENDOR_ID_BROOKTREE
-0878: PCI_DEVICE_ID_BROOKTREE_878

-Hardware supported by the linuxtv.org DVB drivers
-=================================================
-
-  Generally, the DVB hardware manufacturers frequently change the
-  frontends (i.e. tuner / demodulator units) used, usually without
-  changing the product name, revision number or specs. Some cards
-  are also available in versions with different frontends for
-  DVB-S/DVB-C/DVB-T. Thus the frontend drivers are listed separately.
-
-  Note 1: There is no guarantee that every frontend driver works
-  out of the box with every card, because of different wiring.
-
-  Note 2: The demodulator chips can be used with a variety of
-  tuner/PLL chips, and not all combinations are supported. Often
-  the demodulator and tuner/PLL chip are inside a metal box for
-  shielding, and the whole metal box has its own part number.

-* For the user
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-NOTE: This document describes the usage of the high level CI API as
-in accordance to the Linux DVB API. This is a not a documentation for the,
-existing low level CI API.
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-To utilize the High Level CI capabilities,
-
-(1*) This point is valid only for the Twinhan/clones
-  For the Twinhan/Twinhan clones, the dst_ca module handles the CI
-  hardware handling.This module is loaded automatically if a CI
-  (Common Interface, that holds the CAM (Conditional Access Module)
-  is detected.
-
-(2) one requires a userspace application, ca_zap. This small userland
-  application is in charge of sending the descrambling related information
-  to the CAM.
-
-This application requires the following to function properly as of now.
-
-	(a) Tune to a valid channel, with szap.
-	  eg: $ szap -c channels.conf -r "TMC" -x
-
-	(b) a channels.conf containing a valid PMT PID
-	  eg: TMC:11996:h:0:27500:278:512:650:321
-
-	  here 278 is a valid PMT PID. the rest of the values are the
-	  same ones that szap uses.
-
-	(c) after running a szap, you have to run ca_zap, for the
-	  descrambler to function,
-	  eg: $ ca_zap channels.conf "TMC"
-
-	(d) Hopefully enjoy your favourite subscribed channel as you do with
-	  a FTA card.
-
-(3) Currently ca_zap, and dst_test, both are meant for demonstration
-  purposes only, they can become full fledged applications if necessary.
-
-
-* Cards that fall in this category
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-At present the cards that fall in this category are the Twinhan and its
-clones, these cards are available as VVMER, Tomato, Hercules, Orange and
-so on.
-
-* CI modules that are supported
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-The CI module support is largely dependent upon the firmware on the cards
-Some cards do support almost all of the available CI modules. There is
-nothing much that can be done in order to make additional CI modules
-working with these cards.
-
-Modules that have been tested by this driver at present are
-
-(1) Irdeto 1 and 2 from SCM
-(2) Viaccess from SCM
-(3) Dragoncam
-
-* The High level CI API
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-* For the programmer
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-With the High Level CI approach any new card with almost any random
-architecture can be implemented with this style, the definitions
-inside the switch statement can be easily adapted for any card, thereby
-eliminating the need for any additional ioctls.
-
-The disadvantage is that the driver/hardware has to manage the rest. For
-the application programmer it would be as simple as sending/receiving an
-array to/from the CI ioctls as defined in the Linux DVB API. No changes
-have been made in the API to accommodate this feature.
-
-
-* Why the need for another CI interface ?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-This is one of the most commonly asked question. Well a nice question.
-Strictly speaking this is not a new interface.
-
-The CI interface is defined in the DVB API in ca.h as
-
-typedef struct ca_slot_info {
-	int num;               /* slot number */
-
-	int type;              /* CA interface this slot supports */
-#define CA_CI            1     /* CI high level interface */
-#define CA_CI_LINK       2     /* CI link layer level interface */
-#define CA_CI_PHYS       4     /* CI physical layer level interface */
-#define CA_DESCR         8     /* built-in descrambler */
-#define CA_SC          128     /* simple smart card interface */
-
-	unsigned int flags;
-#define CA_CI_MODULE_PRESENT 1 /* module (or card) inserted */
-#define CA_CI_MODULE_READY   2
-} ca_slot_info_t;
-
-
-
-This CI interface follows the CI high level interface, which is not
-implemented by most applications. Hence this area is revisited.
-
-This CI interface is quite different in the case that it tries to
-accommodate all other CI based devices, that fall into the other categories.
-
-This means that this CI interface handles the EN50221 style tags in the
-Application layer only and no session management is taken care of by the
-application. The driver/hardware will take care of all that.
-
-This interface is purely an EN50221 interface exchanging APDU's. This
-means that no session management, link layer or a transport layer do
-exist in this case in the application to driver communication. It is
-as simple as that. The driver/hardware has to take care of that.
-
-
-With this High Level CI interface, the interface can be defined with the
-regular ioctls.
-
-All these ioctls are also valid for the High level CI interface
-
-#define CA_RESET          _IO('o', 128)
-#define CA_GET_CAP        _IOR('o', 129, ca_caps_t)
-#define CA_GET_SLOT_INFO  _IOR('o', 130, ca_slot_info_t)
-#define CA_GET_DESCR_INFO _IOR('o', 131, ca_descr_info_t)
-#define CA_GET_MSG        _IOR('o', 132, ca_msg_t)
-#define CA_SEND_MSG       _IOW('o', 133, ca_msg_t)
-#define CA_SET_DESCR      _IOW('o', 134, ca_descr_t)
-#define CA_SET_PID        _IOW('o', 135, ca_pid_t)
-
-
-On querying the device, the device yields information thus
-
-CA_GET_SLOT_INFO

-APP: Type=[1]
-APP: flags=[1]

-
-(20) ES type=[2] ES pid=[201]  ES length =[0 (0x0)]
-(25) ES type=[4] ES pid=[301]  ES length =[0 (0x0)]
-ca_message length is 25 (0x19) bytes
-EN50221 CA MSG=[ 9f 80 32 19 03 01 2d d1 f0 08 01 09 06 06 04 05 50 ff f1 02 e0 c9 00 00 04 e1 2d 00 00]
-
-
-Not all ioctl's are implemented in the driver from the API, the other
-features of the hardware that cannot be implemented by the API are achieved
-using the CA_GET_MSG and CA_SEND_MSG ioctls. An EN50221 style wrapper is
-used to exchange the data to maintain compatibility with other hardware.
-
-
-/* a message to/from a CI-CAM */
-typedef struct ca_msg {
-	unsigned int index;
-	unsigned int type;
-	unsigned int length;
-	unsigned char msg[256];
-} ca_msg_t;
-
-
-The flow of data can be described thus,

-Some very frequently asked questions about linuxtv-dvb
-
-1. The signal seems to die a few seconds after tuning.
-
-	It's not a bug, it's a feature. Because the frontends have
-	significant power requirements (and hence get very hot), they
-	are powered down if they are unused (i.e. if the frontend device
-	is closed). The dvb-core.o module parameter "dvb_shutdown_timeout"
-	allow you to change the timeout (default 5 seconds). Setting the
-	timeout to 0 disables the timeout feature.
-
-2. How can I watch TV?
-
-	The driver distribution includes some simple utilities which
-	are mainly intended for testing and to demonstrate how the
-	DVB API works.
-
-	Depending on whether you have a DVB-S, DVB-C or DVB-T card, use
-	apps/szap/szap, czap or tzap. You must supply a channel list
-	in ~/.[sct]zap/channels.conf. If you are lucky you can just copy
-	one of the supplied channel lists, or you can create a new one
-	by running apps/scan/scan. If you run scan on an unknown network
-	you might have to supply some start data in apps/scan/initial.h.
-
-	If you have a card with a built-in hardware MPEG-decoder the
-	drivers create a video4linux device (/dev/v4l/video0) which
-	you can use to watch TV with any v4l application. xawtv is known
-	to work. Note that you cannot change channels with xawtv, you
-	have to zap using [sct]zap. If you want a nice application for
-	TV watching and record/playback, have a look at VDR.
-
-	If your card does not have a hardware MPEG decoder you need
-	a software MPEG decoder. Mplayer or xine are known to work.
-	Newsflash: MythTV also has DVB support now.
-	Note: Only very recent versions of Mplayer and xine can decode.
-	MPEG2 transport streams (TS) directly. Then, run
-	'[sct]zap channelname -r' in one xterm, and keep it running,
-	and start 'mplayer - < /dev/dvb/adapter0/dvr0' or
-	'xine stdin://mpeg2 < /dev/dvb/adapter0/dvr0' in a second xterm.
-	That's all far from perfect, but it seems no one has written
-	a nice DVB application which includes a builtin software MPEG
-	decoder yet.
-
-	Newsflash: Newest xine directly supports DVB. Just copy your
-	channels.conf to ~/.xine and start 'xine dvb://', or select
-	the DVB button in the xine GUI. Channel switching works using the
-	numpad pgup/pgdown (NP9 / NP3) keys to scroll through the channel osd
-	menu and pressing numpad-enter to switch to the selected channel.
-
-	Note: Older versions of xine and mplayer understand MPEG program
-	streams (PS) only, and can be used in conjunction with the
-	ts2ps tool from the Metzler Brother's dvb-mpegtools package.

-4. Can't get a signal tuned correctly
-
-	If you are using a Technotrend/Hauppauge DVB-C card *without* analog
-	module, you might have to use module parameter adac=-1 (dvb-ttpci.o).
-
-5. The dvb_net device doesn't give me any packets at all
-
-	Run tcpdump on the dvb0_0 interface. This sets the interface
-	into promiscuous mode so it accepts any packets from the PID
-	you have configured with the dvbnet utility. Check if there
-	are any packets with the IP addr and MAC addr you have
-	configured with ifconfig.
-
-	If tcpdump doesn't give you any output, check the statistics
-	which ifconfig outputs. (Note: If the MAC address is wrong,
-	dvb_net won't get any input; thus you have to run tcpdump
-	before checking the statistics.) If there are no packets at
-	all then maybe the PID is wrong. If there are error packets,
-	then either the PID is wrong or the stream does not conform to
-	the MPE standard (EN 301 192, http://www.etsi.org/). You can
-	use e.g. dvbsnoop for debugging.
-
-6. The dvb_net device doesn't give me any multicast packets
-
-	Check your routes if they include the multicast address range.
-	Additionally make sure that "source validation by reversed path
-	lookup" is disabled:
-	  $ "echo 0 > /proc/sys/net/ipv4/conf/dvb0/rp_filter"
-
-7. What the hell are all those modules that need to be loaded?
-
-	For a dvb-ttpci av7110 based full-featured card the following
-	modules are loaded:
-
-	- videodev: Video4Linux core module. This is the base module that
-	  gives you access to the "analog" tv picture of the av7110 mpeg2
-	  decoder.
-
-	- v4l2-common: common functions for Video4Linux-2 drivers
-
-	- v4l1-compat: backward compatibility layer for Video4Linux-1 legacy
-	  applications
-
-	- dvb-core: DVB core module. This provides you with the
-	  /dev/dvb/adapter entries
-
-	- saa7146: SAA7146 core driver. This is need to access any SAA7146
-	  based card in your system.
-
-	- saa7146_vv: SAA7146 video and vbi functions. These are only needed
-	  for full-featured cards.
-
-	- videobuf-dma-sg: capture helper module for the saa7146_vv driver. This
-	  one is responsible to handle capture buffers.
-
-	- dvb-ttpci: The main driver for AV7110 based, full-featured
-	  DVB-S/C/T cards

-The DVB subsystem currently registers to the sysfs subsystem using the

-
-This means that only the basic information like module loading parameters

-
-Nevertheless it's now possible to add proper udev rules so that the

-
-So, create a new file /etc/udev/scripts/dvb.sh and add the following:
-------------------------------schnipp------------------------------------------------
-#!/bin/sh
-/bin/echo $1 | /bin/sed -e 's,dvb\([0-9]\)\.\([^0-9]*\)\([0-9]\),dvb/adapter\1/\2\3,'

-will tell you the directory where the rules are, most likely it's /etc/udev/rules.d/
-
-Create a new rule file in that directory called "dvb.rule" and add the following line:
-------------------------------schnipp------------------------------------------------
-KERNEL="dvb*", PROGRAM="/etc/udev/scripts/dvb.sh %k", NAME="%c"
-------------------------------schnipp------------------------------------------------
-
-If you want more control over the device nodes (for example a special group membership)
-have a look at "man udev".
-
-For every device that registers to the sysfs subsystem with a "dvb" prefix,
-the helper script /etc/udev/scripts/dvb.sh is invoked, which will then

-		   TuxOnIce 4.0 Internal Documentation.
-			Updated to 23 March 2015
-
-(Please note that incremental image support mentioned in this document is work
-in progress. This document may need updating prior to the actual release of
-4.0!)
-
-1.  Introduction.
-
-    TuxOnIce 4.0 is an addition to the Linux Kernel, designed to
-    allow the user to quickly shutdown and quickly boot a computer, without
-    needing to close documents or programs. It is equivalent to the
-    hibernate facility in some laptops. This implementation, however,
-    requires no special BIOS or hardware support.
-
-    The code in these files is based upon the original implementation
-    prepared by Gabor Kuti and additional work by Pavel Machek and a
-    host of others. This code has been substantially reworked by Nigel
-    Cunningham, again with the help and testing of many others, not the
-    least of whom are Bernard Blackham and Michael Frank. At its heart,
-    however, the operation is essentially the same as Gabor's version.
-
-2.  Overview of operation.
-
-    The basic sequence of operations is as follows:
-
-	a. Quiesce all other activity.
-	b. Ensure enough memory and storage space are available, and attempt
-	   to free memory/storage if necessary.
-	c. Allocate the required memory and storage space.
-	d. Write the image.
-	e. Power down.
-
-    There are a number of complicating factors which mean that things are
-    not as simple as the above would imply, however...
-
-    o The activity of each process must be stopped at a point where it will
-    not be holding locks necessary for saving the image, or unexpectedly
-    restart operations due to something like a timeout and thereby make
-    our image inconsistent.
-
-    o It is desirous that we sync outstanding I/O to disk before calculating
-    image statistics. This reduces corruption if one should suspend but
-    then not resume, and also makes later parts of the operation safer (see
-    below).
-
-    o We need to get as close as we can to an atomic copy of the data.
-    Inconsistencies in the image will result in inconsistent memory contents at
-    resume time, and thus in instability of the system and/or file system
-    corruption. This would appear to imply a maximum image size of one half of
-    the amount of RAM, but we have a solution... (again, below).
-
-    o In 2.6 and later, we choose to play nicely with the other suspend-to-disk
-    implementations.
-
-3.  Detailed description of internals.
-
-    a. Quiescing activity.
-
-    Safely quiescing the system is achieved using three separate but related
-    aspects.
-
-    First, we use the vanilla kerne's support for freezing processes. This code
-    is based on the observation that the vast majority of processes don't need
-    to run during suspend. They can be 'frozen'. The kernel therefore
-    implements a refrigerator routine, which processes enter and in which they
-    remain until the cycle is complete. Processes enter the refrigerator via
-    try_to_freeze() invocations at appropriate places.  A process cannot be
-    frozen in any old place. It must not be holding locks that will be needed
-    for writing the image or freezing other processes. For this reason,
-    userspace processes generally enter the refrigerator via the signal
-    handling code, and kernel threads at the place in their event loops where
-    they drop locks and yield to other processes or sleep. The task of freezing
-    processes is complicated by the fact that there can be interdependencies
-    between processes. Freezing process A before process B may mean that
-    process B cannot be frozen, because it stops at waiting for process A
-    rather than in the refrigerator. This issue is seen where userspace waits
-    on freezeable kernel threads or fuse filesystem threads. To address this
-    issue, we implement the following algorithm for quiescing activity:
-
-	- Freeze filesystems (including fuse - userspace programs starting
-		new requests are immediately frozen; programs already running
-		requests complete their work before being frozen in the next
-		step)
-	- Freeze userspace
-	- Thaw filesystems (this is safe now that userspace is frozen and no
-		fuse requests are outstanding).
-	- Invoke sys_sync (noop on fuse).
-	- Freeze filesystems
-	- Freeze kernel threads
-
-    If we need to free memory, we thaw kernel threads and filesystems, but not
-    userspace. We can then free caches without worrying about deadlocks due to
-    swap files being on frozen filesystems or such like.
-
-    b. Ensure enough memory & storage are available.
-
-    We have a number of constraints to meet in order to be able to successfully
-    suspend and resume.
-
-    First, the image will be written in two parts, described below. One of
-    these parts needs to have an atomic copy made, which of course implies a
-    maximum size of one half of the amount of system memory. The other part
-    ('pageset') is not atomically copied, and can therefore be as large or
-    small as desired.
-
-    Second, we have constraints on the amount of storage available. In these
-    calculations, we may also consider any compression that will be done. The
-    cryptoapi module allows the user to configure an expected compression ratio.
-
-    Third, the user can specify an arbitrary limit on the image size, in
-    megabytes. This limit is treated as a soft limit, so that we don't fail the
-    attempt to suspend if we cannot meet this constraint.
-
-    c. Allocate the required memory and storage space.
-
-    Having done the initial freeze, we determine whether the above constraints
-    are met, and seek to allocate the metadata for the image. If the constraints
-    are not met, or we fail to allocate the required space for the metadata, we
-    seek to free the amount of memory that we calculate is needed and try again.
-    We allow up to four iterations of this loop before aborting the cycle. If
-    we do fail, it should only be because of a bug in TuxOnIce's calculations
-    or the vanilla kernel code for freeing memory.
-
-    These steps are merged together in the prepare_image function, found in
-    prepare_image.c. The functions are merged because of the cyclical nature
-    of the problem of calculating how much memory and storage is needed. Since
-    the data structures containing the information about the image must
-    themselves take memory and use storage, the amount of memory and storage
-    required changes as we prepare the image. Since the changes are not large,
-    only one or two iterations will be required to achieve a solution.
-
-    The recursive nature of the algorithm is miminised by keeping user space
-    frozen while preparing the image, and by the fact that our records of which
-    pages are to be saved and which pageset they are saved in use bitmaps (so
-    that changes in number or fragmentation of the pages to be saved don't
-    feedback via changes in the amount of memory needed for metadata). The
-    recursiveness is thus limited to any extra slab pages allocated to store the
-    extents that record storage used, and the effects of seeking to free memory.
-
-    d. Write the image.
-
-    We previously mentioned the need to create an atomic copy of the data, and
-    the half-of-memory limitation that is implied in this. This limitation is
-    circumvented by dividing the memory to be saved into two parts, called
-    pagesets.
-
-    Pageset2 contains most of the page cache - the pages on the active and
-    inactive LRU lists that aren't needed or modified while TuxOnIce is
-    running, so they can be safely written without an atomic copy. They are
-    therefore saved first and reloaded last. While saving these pages,
-    TuxOnIce carefully ensures that the work of writing the pages doesn't make
-    the image inconsistent. With the support for Kernel (Video) Mode Setting
-    going into the kernel at the time of writing, we need to check for pages
-    on the LRU that are used by KMS, and exclude them from pageset2. They are
-    atomically copied as part of pageset 1.
-
-    Once pageset2 has been saved, we prepare to do the atomic copy of remaining
-    memory. As part of the preparation, we power down drivers, thereby providing
-    them with the opportunity to have their state recorded in the image. The
-    amount of memory allocated by drivers for this is usually negligible, but if
-    DRI is in use, video drivers may require significants amounts. Ideally we
-    would be able to query drivers while preparing the image as to the amount of
-    memory they will need. Unfortunately no such mechanism exists at the time of
-    writing. For this reason, TuxOnIce allows the user to set an
-    'extra_pages_allowance', which is used to seek to ensure sufficient memory
-    is available for drivers at this point. TuxOnIce also lets the user set this
-    value to 0. In this case, a test driver suspend is done while preparing the
-    image, and the difference (plus a margin) used instead. TuxOnIce will also
-    automatically restart the hibernation process (twice at most) if it finds
-    that the extra pages allowance is not sufficient. It will then use what was
-    actually needed (plus a margin, again). Failure to hibernate should thus
-    be an extremely rare occurence.
-
-    Having suspended the drivers, we save the CPU context before making an
-    atomic copy of pageset1, resuming the drivers and saving the atomic copy.
-    After saving the two pagesets, we just need to save our metadata before
-    powering down.
-
-    As we mentioned earlier, the contents of pageset2 pages aren't needed once
-    they've been saved. We therefore use them as the destination of our atomic
-    copy. In the unlikely event that pageset1 is larger, extra pages are
-    allocated while the image is being prepared. This is normally only a real
-    possibility when the system has just been booted and the page cache is
-    small.
-
-    This is where we need to be careful about syncing, however. Pageset2 will
-    probably contain filesystem meta data. If this is overwritten with pageset1
-    and then a sync occurs, the filesystem will be corrupted - at least until
-    resume time and another sync of the restored data. Since there is a
-    possibility that the user might not resume or (may it never be!) that
-    TuxOnIce might oops, we do our utmost to avoid syncing filesystems after
-    copying pageset1.
-
-    e. Incremental images
-
-    TuxOnIce 4.0 introduces a new incremental image mode which changes things a
-    little. When incremental images are enabled, we save a 'normal' image the
-    first time we hibernate. One resume however, we do not free the image or
-    the associated storage. Instead, it is retained until the next attempt at
-    hibernating and a mechanism is enabled which is used to track which pages
-    of memory are modified between the two cycles. The modified pages can then
-    be added to the existing image, rather than unmodified pages being saved
-    again unnecessarily.
-
-    Incremental image support is available in 64 bit Linux only, due to the
-    requirement for extra page flags.
-
-    This support is accomplished in the following way:
-
-    1) Tracking of pages.
-
-    The tracking of changed pages is accomplished using the page fault
-    mechanism. When we reach a point at which we want to start tracking
-    changes, most pages are marked read-only and also flagged as being
-    read-only because of this support. Since this cannot happen for every page
-    of RAM, some are marked as untracked and always treated as modified whn
-    preparing an incremental iamge. When a process attempts to modify a page
-    that is marked read-only in this way, a page fault occurs, with TuxOnIce
-    code marking the page writable and dirty before allowing the write to
-    continue. In this way, the effect of incremental images on performance is
-    minimised - a page only causes a fault once. Small modifications to the
-    page allocator further reduce the number of faults that occur - free pages
-    are not tracked; they are made writable and marked as dirty as part of
-    being allocated.
-
-    2) Saving the incremental image / atomicity.
-
-    The page fault mechanism is also used to improve the means by which
-    atomicity of the image is acheived. When it is time to do an atomic copy,
-    the flags for pages are reset, with the result being that it is no longer
-    necessary for us to do an atomic of pageset1. Instead, we normally write
-    the uncopied pages to disk. When an attempt is made to modify a page that
-    has not yet been saved, the page-fault mechanism makes a copy of the page
-    prior to allowing the write. This copy is then written to disk. Likewise,
-    on resume, if a process attempts to write to a page that has been read
-    while the rest of the image is still being loaded, a copy of that page is
-    made prior to the write being allowed. At the end of loading the image,
-    modified pages can thus be restored to their 'atomic copy' contents prior
-    to restarting normal operation. We also mark pages that are yet to be read
-    as invalid PFNs, so that we can capture as a bug any attempt by a
-    half-restored kernel to access a page that hasn't yet been reloaded.
-
-    f. Power down.
-
-    Powering down uses standard kernel routines. TuxOnIce supports powering down
-    using the ACPI S3, S4 and S5 methods or the kernel's non-ACPI power-off.
-    Supporting suspend to ram (S3) as a power off option might sound strange,
-    but it allows the user to quickly get their system up and running again if
-    the battery doesn't run out (we just need to re-read the overwritten pages)
-    and if the battery does run out (or the user removes power), they can still
-    resume.
-
-4.  Data Structures.
-
-    TuxOnIce uses three main structures to store its metadata and configuration
-    information:
-
-    a) Pageflags bitmaps.
-
-    TuxOnIce records which pages will be in pageset1, pageset2, the destination
-    of the atomic copy and the source of the atomically restored image using
-    bitmaps. The code used is that written for swsusp, with small improvements
-    to match TuxOnIce's requirements.
-
-    The pageset1 bitmap is thus easily stored in the image header for use at
-    resume time.
-
-    As mentioned above, using bitmaps also means that the amount of memory and
-    storage required for recording the above information is constant. This
-    greatly simplifies the work of preparing the image. In earlier versions of
-    TuxOnIce, extents were used to record which pages would be stored. In that
-    case, however, eating memory could result in greater fragmentation of the
-    lists of pages, which in turn required more memory to store the extents and
-    more storage in the image header. These could in turn require further
-    freeing of memory, and another iteration. All of this complexity is removed
-    by having bitmaps.
-
-    Bitmaps also make a lot of sense because TuxOnIce only ever iterates
-    through the lists. There is therefore no cost to not being able to find the
-    nth page in order 0 time. We only need to worry about the cost of finding
-    the n+1th page, given the location of the nth page. Bitwise optimisations
-    help here.
-
-    b) Extents for block data.
-
-    TuxOnIce supports writing the image to multiple block devices. In the case
-    of swap, multiple partitions and/or files may be in use, and we happily use
-    them all (with the exception of compcache pages, which we allocate but do
-    not use). This use of multiple block devices is accomplished as follows:
-
-    Whatever the actual source of the allocated storage, the destination of the
-    image can be viewed in terms of one or more block devices, and on each
-    device, a list of sectors. To simplify matters, we only use contiguous,
-    PAGE_SIZE aligned sectors, like the swap code does.
-
-    Since sector numbers on each bdev may well not start at 0, it makes much
-    more sense to use extents here. Contiguous ranges of pages can thus be
-    represented in the extents by contiguous values.
-
-    Variations in block size are taken account of in transforming this data
-    into the parameters for bio submission.
-
-    We can thus implement a layer of abstraction wherein the core of TuxOnIce
-    doesn't have to worry about which device we're currently writing to or
-    where in the device we are. It simply requests that the next page in the
-    pageset or header be written, leaving the details to this lower layer.
-    The lower layer remembers where in the sequence of devices and blocks each
-    pageset starts. The header always starts at the beginning of the allocated
-    storage.
-
-    So extents are:
-
-    struct extent {
-      unsigned long minimum, maximum;
-      struct extent *next;
-    }
-
-    These are combined into chains of extents for a device:
-
-    struct extent_chain {
-      int size; /* size of the extent ie sum (max-min+1) */
-      int allocs, frees;
-      char *name;
-      struct extent *first, *last_touched;
-    };
-
-    For each bdev, we need to store a little more info (simplified definition):
-
-    struct toi_bdev_info {
-       struct block_device *bdev;
-
-       char uuid[17];
-       dev_t dev_t;
-       int bmap_shift;
-       int blocks_per_page;
-    };
-
-    The uuid is the main means used to identify the device in the storage
-    image. This means we can cope with the dev_t representation of a device
-    changing between saving the image and restoring it, as may happen on some
-    bioses or in the LVM case.
-
-    bmap_shift and blocks_per_page apply the effects of variations in blocks
-    per page settings for the filesystem and underlying bdev. For most
-    filesystems, these are the same, but for xfs, they can have independant
-    values.
-
-    Combining these two structures together, we have everything we need to
-    record what devices and what blocks on each device are being used to
-    store the image, and to submit i/o using bio_submit.
-
-    The last elements in the picture are a means of recording how the storage
-    is being used.
-
-    We do this first and foremost by implementing a layer of abstraction on
-    top of the devices and extent chains which allows us to view however many
-    devices there might be as one long storage tape, with a single 'head' that
-    tracks a 'current position' on the tape:
-
-    struct extent_iterate_state {
-      struct extent_chain *chains;
-      int num_chains;
-      int current_chain;
-      struct extent *current_extent;
-      unsigned long current_offset;
-    };
-
-    That is, *chains points to an array of size num_chains of extent chains.
-    For the filewriter, this is always a single chain. For the swapwriter, the
-    array is of size MAX_SWAPFILES.
-
-    current_chain, current_extent and current_offset thus point to the current
-    index in the chains array (and into a matching array of struct
-    suspend_bdev_info), the current extent in that chain (to optimise access),
-    and the current value in the offset.
-
-    The image is divided into three parts:
-    - The header
-    - Pageset 1
-    - Pageset 2
-
-    The header always starts at the first device and first block. We know its
-    size before we begin to save the image because we carefully account for
-    everything that will be stored in it.
-
-    The second pageset (LRU) is stored first. It begins on the next page after
-    the end of the header.
-
-    The first pageset is stored second. It's start location is only known once
-    pageset2 has been saved, since pageset2 may be compressed as it is written.
-    This location is thus recorded at the end of saving pageset2. It is page
-    aligned also.
-
-    Since this information is needed at resume time, and the location of extents
-    in memory will differ at resume time, this needs to be stored in a portable
-    way:
-
-    struct extent_iterate_saved_state {
-        int chain_num;
-        int extent_num;
-        unsigned long offset;
-    };
-
-    We can thus implement a layer of abstraction wherein the core of TuxOnIce
-    doesn't have to worry about which device we're currently writing to or
-    where in the device we are. It simply requests that the next page in the
-    pageset or header be written, leaving the details to this layer, and
-    invokes the routines to remember and restore the position, without having
-    to worry about the details of how the data is arranged on disk or such like.
-
-    c) Modules
-
-    One aim in designing TuxOnIce was to make it flexible. We wanted to allow
-    for the implementation of different methods of transforming a page to be
-    written to disk and different methods of getting the pages stored.
-
-    In early versions (the betas and perhaps Suspend1), compression support was
-    inlined in the image writing code, and the data structures and code for
-    managing swap were intertwined with the rest of the code. A number of people
-    had expressed interest in implementing image encryption, and alternative
-    methods of storing the image.
-
-    In order to achieve this, TuxOnIce was given a modular design.
-
-    A module is a single file which encapsulates the functionality needed
-    to transform a pageset of data (encryption or compression, for example),
-    or to write the pageset to a device. The former type of module is called
-    a 'page-transformer', the later a 'writer'.
-
-    Modules are linked together in pipeline fashion. There may be zero or more
-    page transformers in a pipeline, and there is always exactly one writer.
-    The pipeline follows this pattern:
-
-		---------------------------------
-		|          TuxOnIce Core        |
-		---------------------------------
-				|
-				|
-		---------------------------------
-		|	Page transformer 1	|
-		---------------------------------
-				|
-				|
-		---------------------------------
-		|	Page transformer 2	|
-		---------------------------------
-				|
-				|
-		---------------------------------
-		|            Writer		|
-		---------------------------------
-
-    During the writing of an image, the core code feeds pages one at a time
-    to the first module. This module performs whatever transformations it
-    implements on the incoming data, completely consuming the incoming data and
-    feeding output in a similar manner to the next module.
-
-    All routines are SMP safe, and the final result of the transformations is
-    written with an index (provided by the core) and size of the output by the
-    writer. As a result, we can have multithreaded I/O without needing to
-    worry about the sequence in which pages are written (or read).
-
-    During reading, the pipeline works in the reverse direction. The core code
-    calls the first module with the address of a buffer which should be filled.
-    (Note that the buffer size is always PAGE_SIZE at this time). This module
-    will in turn request data from the next module and so on down until the
-    writer is made to read from the stored image.
-
-    Part of definition of the structure of a module thus looks like this:
-
-        int (*rw_init) (int rw, int stream_number);
-        int (*rw_cleanup) (int rw);
-        int (*write_chunk) (struct page *buffer_page);
-        int (*read_chunk) (struct page *buffer_page, int sync);
-
-    It should be noted that the _cleanup routine may be called before the
-    full stream of data has been read or written. While writing the image,
-    the user may (depending upon settings) choose to abort suspending, and
-    if we are in the midst of writing the last portion of the image, a portion
-    of the second pageset may be reread. This may also happen if an error
-    occurs and we seek to abort the process of writing the image.
-
-    The modular design is also useful in a number of other ways. It provides
-    a means where by we can add support for:
-
-    - providing overall initialisation and cleanup routines;
-    - serialising configuration information in the image header;
-    - providing debugging information to the user;
-    - determining memory and image storage requirements;
-    - dis/enabling components at run-time;
-    - configuring the module (see below);
-
-    ...and routines for writers specific to their work:
-    - Parsing a resume= location;
-    - Determining whether an image exists;
-    - Marking a resume as having been attempted;
-    - Invalidating an image;
-
-    Since some parts of the core - the user interface and storage manager
-    support - have use for some of these functions, they are registered as
-    'miscellaneous' modules as well.
-
-    d) Sysfs data structures.
-
-    This brings us naturally to support for configuring TuxOnIce. We desired to
-    provide a way to make TuxOnIce as flexible and configurable as possible.
-    The user shouldn't have to reboot just because they want to now hibernate to
-    a file instead of a partition, for example.
-
-    To accomplish this, TuxOnIce implements a very generic means whereby the
-    core and modules can register new sysfs entries. All TuxOnIce entries use
-    a single _store and _show routine, both of which are found in
-    tuxonice_sysfs.c in the kernel/power directory. These routines handle the
-    most common operations - getting and setting the values of bits, integers,
-    longs, unsigned longs and strings in one place, and allow overrides for
-    customised get and set options as well as side-effect routines for all
-    reads and writes.
-
-    When combined with some simple macros, a new sysfs entry can then be defined
-    in just a couple of lines:
-
-        SYSFS_INT("progress_granularity", SYSFS_RW, &progress_granularity, 1,
-                        2048, 0, NULL),
-
-    This defines a sysfs entry named "progress_granularity" which is rw and
-    allows the user to access an integer stored at &progress_granularity, giving
-    it a value between 1 and 2048 inclusive.
-
-    Sysfs entries are registered under /sys/power/tuxonice, and entries for
-    modules are located in a subdirectory named after the module.

-
-1. What is it?
-
-   Imagine you're sitting at your computer, working away. For some reason, you
-   need to turn off your computer for a while - perhaps it's time to go home
-   for the day. When you come back to your computer next, you're going to want
-   to carry on where you left off. Now imagine that you could push a button and
-   have your computer store the contents of its memory to disk and power down.
-   Then, when you next start up your computer, it loads that image back into
-   memory and you can carry on from where you were, just as if you'd never
-   turned the computer off. You have far less time to start up, no reopening of
-   applications or finding what directory you put that file in yesterday.
-   That's what TuxOnIce does.
-
-   TuxOnIce has a long heritage. It began life as work by Gabor Kuti, who,
-   with some help from Pavel Machek, got an early version going in 1999. The
-   project was then taken over by Florent Chabaud while still in alpha version
-   numbers. Nigel Cunningham came on the scene when Florent was unable to
-   continue, moving the project into betas, then 1.0, 2.0 and so on up to
-   the present series. During the 2.0 series, the name was contracted to
-   Suspend2 and the website suspend2.net created. Beginning around July 2007,
-   a transition to calling the software TuxOnIce was made, to seek to help
-   make it clear that TuxOnIce is more concerned with hibernation than suspend
-   to ram.
-
-   Pavel Machek's swsusp code, which was merged around 2.5.17 retains the
-   original name, and was essentially a fork of the beta code until Rafael
-   Wysocki came on the scene in 2005 and began to improve it further.
-
-2. Why would you want it?
-
-   Why wouldn't you want it?
-
-   Being able to save the state of your system and quickly restore it improves
-   your productivity - you get a useful system in far less time than through
-   the normal boot process. You also get to be completely 'green', using zero
-   power, or as close to that as possible (the computer may still provide
-   minimal power to some devices, so they can initiate a power on, but that
-   will be the same amount of power as would be used if you told the computer
-   to shutdown.
-
-3. What do you need to use it?
-
-   a. Kernel Support.
-
-   i) The TuxOnIce patch.
-
-   TuxOnIce is part of the Linux Kernel. This version is not part of Linus's
-   2.6 tree at the moment, so you will need to download the kernel source and
-   apply the latest patch. Having done that, enable the appropriate options in
-   make [menu|x]config (under Power Management Options - look for "Enhanced
-   Hibernation"), compile and install your kernel. TuxOnIce works with SMP,
-   Highmem, preemption, fuse filesystems, x86-32, PPC and x86_64.
-
-   TuxOnIce patches are available from http://tuxonice.net.
-
-   ii) Compression support.
-
-   Compression support is implemented via the cryptoapi. You will therefore want
-   to select any Cryptoapi transforms that you want to use on your image from
-   the Cryptoapi menu while configuring your kernel. We recommend the use of the
-   LZO compression method - it is very fast and still achieves good compression.
-
-   You can also tell TuxOnIce to write its image to an encrypted and/or
-   compressed filesystem/swap partition. In that case, you don't need to do
-   anything special for TuxOnIce when it comes to kernel configuration.
-
-   iii) Configuring other options.
-
-   While you're configuring your kernel, try to configure as much as possible
-   to build as modules. We recommend this because there are a number of drivers
-   that are still in the process of implementing proper power management
-   support. In those cases, the best way to work around their current lack is
-   to build them as modules and remove the modules while hibernating. You might
-   also bug the driver authors to get their support up to speed, or even help!
-
-   b. Storage.
-
-   i) Swap.
-
-   TuxOnIce can store the hibernation image in your swap partition, a swap file or
-   a combination thereof. Whichever combination you choose, you will probably
-   want to create enough swap space to store the largest image you could have,
-   plus the space you'd normally use for swap. A good rule of thumb would be
-   to calculate the amount of swap you'd want without using TuxOnIce, and then
-   add the amount of memory you have. This swapspace can be arranged in any way
-   you'd like. It can be in one partition or file, or spread over a number. The
-   only requirement is that they be active when you start a hibernation cycle.
-
-   There is one exception to this requirement. TuxOnIce has the ability to turn
-   on one swap file or partition at the start of hibernating and turn it back off
-   at the end. If you want to ensure you have enough memory to store a image
-   when your memory is fully used, you might want to make one swap partition or
-   file for 'normal' use, and another for TuxOnIce to activate & deactivate
-   automatically. (Further details below).
-
-   ii) Normal files.
-
-   TuxOnIce includes a 'file allocator'. The file allocator can store your
-   image in a simple file. Since Linux has the concept of everything being a
-   file, this is more powerful than it initially sounds. If, for example, you
-   were to set up a network block device file, you could hibernate to a network
-   server. This has been tested and works to a point, but nbd itself isn't
-   stateless enough for our purposes.
-
-   Take extra care when setting up the file allocator. If you just type
-   commands without thinking and then try to hibernate, you could cause
-   irreversible corruption on your filesystems! Make sure you have backups.
-
-   Most people will only want to hibernate to a local file. To achieve that, do
-   something along the lines of:
-
-   echo "TuxOnIce" > /hibernation-file
-   dd if=/dev/zero bs=1M count=512 >> /hibernation-file
-
-   This will create a 512MB file called /hibernation-file. To get TuxOnIce to use
-   it:
-
-   echo /hibernation-file > /sys/power/tuxonice/file/target
-
-   Then
-
-   cat /sys/power/tuxonice/resume
-
-   Put the results of this into your bootloader's configuration (see also step
-   C, below):
-
-   ---EXAMPLE-ONLY-DON'T-COPY-AND-PASTE---
-   # cat /sys/power/tuxonice/resume
-   file:/dev/hda2:0x1e001
-
-   In this example, we would edit the append= line of our lilo.conf|menu.lst
-   so that it included:
-
-   resume=file:/dev/hda2:0x1e001
-   ---EXAMPLE-ONLY-DON'T-COPY-AND-PASTE---
-
-   For those who are thinking 'Could I make the file sparse?', the answer is
-   'No!'. At the moment, there is no way for TuxOnIce to fill in the holes in
-   a sparse file while hibernating. In the longer term (post merge!), I'd like
-   to change things so that the file could be dynamically resized and have
-   holes filled as needed. Right now, however, that's not possible and not a
-   priority.
-
-   c. Bootloader configuration.
-
-   Using TuxOnIce also requires that you add an extra parameter to
-   your lilo.conf or equivalent. Here's an example for a swap partition:
-
-   append="resume=swap:/dev/hda1"
-
-   This would tell TuxOnIce that /dev/hda1 is a swap partition you
-   have. TuxOnIce will use the swap signature of this partition as a
-   pointer to your data when you hibernate. This means that (in this example)
-   /dev/hda1 doesn't need to be _the_ swap partition where all of your data
-   is actually stored. It just needs to be a swap partition that has a
-   valid signature.
-
-   You don't need to have a swap partition for this purpose. TuxOnIce
-   can also use a swap file, but usage is a little more complex. Having made
-   your swap file, turn it on and do
-
-   cat /sys/power/tuxonice/swap/headerlocations
-
-   (this assumes you've already compiled your kernel with TuxOnIce
-   support and booted it). The results of the cat command will tell you
-   what you need to put in lilo.conf:
-
-   For swap partitions like /dev/hda1, simply use resume=/dev/hda1.
-   For swapfile `swapfile`, use resume=swap:/dev/hda2:0x242d.
-
-   If the swapfile changes for any reason (it is moved to a different
-   location, it is deleted and recreated, or the filesystem is
-   defragmented) then you will have to check
-   /sys/power/tuxonice/swap/headerlocations for a new resume_block value.
-
-   Once you've compiled and installed the kernel and adjusted your bootloader
-   configuration, you should only need to reboot for the most basic part
-   of TuxOnIce to be ready.
-
-   If you only compile in the swap allocator, or only compile in the file
-   allocator, you don't need to add the "swap:" part of the resume=
-   parameters above. resume=/dev/hda2:0x242d will work just as well. If you
-   have compiled both and your storage is on swap, you can also use this
-   format (the swap allocator is the default allocator).
-
-   When compiling your kernel, one of the options in the 'Power Management
-   Support' menu, just above the 'Enhanced Hibernation (TuxOnIce)' entry is
-   called 'Default resume partition'. This can be used to set a default value
-   for the resume= parameter.
-
-   d. The hibernate script.
-
-   Since the driver model in 2.6 kernels is still being developed, you may need
-   to do more than just configure TuxOnIce. Users of TuxOnIce usually start the
-   process via a script which prepares for the hibernation cycle, tells the
-   kernel to do its stuff and then restore things afterwards. This script might
-   involve:
-
-   - Switching to a text console and back if X doesn't like the video card
-     status on resume.
-   - Un/reloading drivers that don't play well with hibernation.
-
-   Note that you might not be able to unload some drivers if there are
-   processes using them. You might have to kill off processes that hold
-   devices open. Hint: if your X server accesses an USB mouse, doing a
-   'chvt' to a text console releases the device and you can unload the
-   module.
-
-   Check out the latest script (available on tuxonice.net).
-
-   e. The userspace user interface.
-
-   TuxOnIce has very limited support for displaying status if you only apply
-   the kernel patch - it can printk messages, but that is all. In addition,
-   some of the functions mentioned in this document (such as cancelling a cycle
-   or performing interactive debugging) are unavailable. To utilise these
-   functions, or simply get a nice display, you need the 'userui' component.
-   Userui comes in three flavours, usplash, fbsplash and text. Text should
-   work on any console. Usplash and fbsplash require the appropriate
-   (distro specific?) support.
-
-   To utilise a userui, TuxOnIce just needs to be told where to find the
-   userspace binary:
-
-   echo "/usr/local/sbin/tuxoniceui_fbsplash" > /sys/power/tuxonice/user_interface/program
-
-   The hibernate script can do this for you, and a default value for this
-   setting can be configured when compiling the kernel. This path is also
-   stored in the image header, so if you have an initrd or initramfs, you can
-   use the userui during the first part of resuming (prior to the atomic
-   restore) by putting the binary in the same path in your initrd/ramfs.
-   Alternatively, you can put it in a different location and do an echo
-   similar to the above prior to the echo > do_resume. The value saved in the
-   image header will then be ignored.
-
-4. Why not just use the version already in the kernel?
-
-   The version in the vanilla kernel has a number of drawbacks. The most
-   serious of these are:
-	- it has a maximum image size of 1/2 total memory;
-	- it doesn't allocate storage until after it has snapshotted memory.
-	  This means that you can't be sure hibernating will work until you
-	  see it start to write the image;
-	- it does not allow you to press escape to cancel a cycle;
-	- it does not allow you to press escape to cancel resuming;
-	- it does not allow you to automatically swapon a file when
-	  starting a cycle;
-	- it does not allow you to use multiple swap partitions or files;
-	- it does not allow you to use ordinary files;
-	- it just invalidates an image and continues to boot if you
-	  accidentally boot the wrong kernel after hibernating;
-	- it doesn't support any sort of nice display while hibernating;
-	- it is moving toward requiring that you have an initrd/initramfs
-	  to ever have a hope of resuming (uswsusp). While uswsusp will
-	  address some of the concerns above, it won't address all of them,
-          and will be more complicated to get set up;
-        - it doesn't have support for suspend-to-both (write a hibernation
-	  image, then suspend to ram; I think this is known as ReadySafe
-	  under M$).
-
-5. How do you use it?
-
-   A hibernation cycle can be started directly by doing:
-
-	echo > /sys/power/tuxonice/do_hibernate
-
-   In practice, though, you'll probably want to use the hibernate script
-   to unload modules, configure the kernel the way you like it and so on.
-   In that case, you'd do (as root):
-
-	hibernate
-
-   See the hibernate script's man page for more details on the options it
-   takes.
-
-   If you're using the text or splash user interface modules, one feature of
-   TuxOnIce that you might find useful is that you can press Escape at any time
-   during hibernating, and the process will be aborted.
-
-   Due to the way hibernation works, this means you'll have your system back and
-   perfectly usable almost instantly. The only exception is when it's at the
-   very end of writing the image. Then it will need to reload a small (usually
-   4-50MBs, depending upon the image characteristics) portion first.
-
-   Likewise, when resuming, you can press escape and resuming will be aborted.
-   The computer will then powerdown again according to settings at that time for
-   the powerdown method or rebooting.
-
-   You can change the settings for powering down while the image is being
-   written by pressing 'R' to toggle rebooting and 'O' to toggle between
-   suspending to ram and powering down completely).
-
-   If you run into problems with resuming, adding the "noresume" option to
-   the kernel command line will let you skip the resume step and recover your
-   system. This option shouldn't normally be needed, because TuxOnIce modifies
-   the image header prior to the atomic restore, and will thus prompt you
-   if it detects that you've tried to resume an image before (this flag is
-   removed if you press Escape to cancel a resume, so you won't be prompted
-   then).
-
-   Recent kernels (2.6.24 onwards) add support for resuming from a different
-   kernel to the one that was hibernated (thanks to Rafael for his work on
-   this - I've just embraced and enhanced the support for TuxOnIce). This
-   should further reduce the need for you to use the noresume option.
-
-6. What do all those entries in /sys/power/tuxonice do?
-
-   /sys/power/tuxonice is the directory which contains files you can use to
-   tune and configure TuxOnIce to your liking. The exact contents of
-   the directory will depend upon the version of TuxOnIce you're
-   running and the options you selected at compile time. In the following
-   descriptions, names in brackets refer to compile time options.
-   (Note that they're all dependant upon you having selected CONFIG_TUXONICE
-   in the first place!).
-
-   Since the values of these settings can open potential security risks, the
-   writeable ones are accessible only to the root user. You may want to
-   configure sudo to allow you to invoke your hibernate script as an ordinary
-   user.
-
-   - alloc/failure_test
-
-   This debugging option provides a way of testing TuxOnIce's handling of
-   memory allocation failures. Each allocation type that TuxOnIce makes has
-   been given a unique number (see the source code). Echo the appropriate
-   number into this entry, and when TuxOnIce attempts to do that allocation,
-   it will pretend there was a failure and act accordingly.
-
-   - alloc/find_max_mem_allocated
-
-   This debugging option will cause TuxOnIce to find the maximum amount of
-   memory it used during a cycle, and report that information in debugging
-   information at the end of the cycle.
-
-   - alt_resume_param
-
-   Instead of powering down after writing a hibernation image, TuxOnIce
-   supports resuming from a different image. This entry lets you set the
-   location of the signature for that image (the resume= value you'd use
-   for it). Using an alternate image and keep_image mode, you can do things
-   like using an alternate image to power down an uninterruptible power
-   supply.
-
-   - block_io/target_outstanding_io
-
-   This value controls the amount of memory that the block I/O code says it
-   needs when the core code is calculating how much memory is needed for
-   hibernating and for resuming. It doesn't directly control the amount of
-   I/O that is submitted at any one time - that depends on the amount of
-   available memory (we may have more available than we asked for), the
-   throughput that is being achieved and the ability of the CPU to keep up
-   with disk throughput (particularly where we're compressing pages).
-
-   - checksum/enabled
-
-   Use cryptoapi hashing routines to verify that Pageset2 pages don't change
-   while we're saving the first part of the image, and to get any pages that
-   do change resaved in the atomic copy. This should normally not be needed,
-   but if you're seeing issues, please enable this. If your issues stop you
-   being able to resume, enable this option, hibernate and cancel the cycle
-   after the atomic copy is done. If the debugging info shows a non-zero
-   number of pages resaved, please report this to Nigel.
-
-   - compression/algorithm
-
-   Set the cryptoapi algorithm used for compressing the image.
-
-   - compression/expected_compression
-
-   These values allow you to set an expected compression ratio, which TuxOnice
-   will use in calculating whether it meets constraints on the image size. If
-   this expected compression ratio is not attained, the hibernation cycle will
-   abort, so it is wise to allow some spare. You can see what compression
-   ratio is achieved in the logs after hibernating.
-
-   - debug_info:
-
-   This file returns information about your configuration that may be helpful
-   in diagnosing problems with hibernating.
-
-   - did_suspend_to_both:
-
-   This file can be used when you hibernate with powerdown method 3 (ie suspend
-   to ram after writing the image). There can be two outcomes in this case. We
-   can resume from the suspend-to-ram before the battery runs out, or we can run
-   out of juice and and up resuming like normal. This entry lets you find out,
-   post resume, which way we went. If the value is 1, we resumed from suspend
-   to ram. This can be useful when actions need to be run post suspend-to-ram
-   that don't need to be run if we did the normal resume from power off.
-
-   - do_hibernate:
-
-   When anything is written to this file, the kernel side of TuxOnIce will
-   begin to attempt to write an image to disk and power down. You'll normally
-   want to run the hibernate script instead, to get modules unloaded first.
-
-   - do_resume:
-
-   When anything is written to this file TuxOnIce will attempt to read and
-   restore an image. If there is no image, it will return almost immediately.
-   If an image exists, the echo > will never return. Instead, the original
-   kernel context will be restored and the original echo > do_hibernate will
-   return.
-
-   - */enabled
-
-   These option can be used to temporarily disable various parts of TuxOnIce.
-
-   - extra_pages_allowance
-
-   When TuxOnIce does its atomic copy, it calls the driver model suspend
-   and resume methods. If you have DRI enabled with a driver such as fglrx,
-   this can result in the driver allocating a substantial amount of memory
-   for storing its state. Extra_pages_allowance tells TuxOnIce how much
-   extra memory it should ensure is available for those allocations. If
-   your attempts at hibernating end with a message in dmesg indicating that
-   insufficient extra pages were allowed, you need to increase this value.
-
-   - file/target:
-
-   Read this value to get the current setting. Write to it to point TuxOnice
-   at a new storage location for the file allocator. See section 3.b.ii above
-   for details of how to set up the file allocator.
-
-   - freezer_test
-
-   This entry can be used to get TuxOnIce to just test the freezer and prepare
-   an image without actually doing a hibernation cycle. It is useful for
-   diagnosing freezing and image preparation issues.
-
-   - full_pageset2
-
-   TuxOnIce divides the pages that are stored in an image into two sets. The
-   difference between the two sets is that pages in pageset 1 are atomically
-   copied, and pages in pageset 2 are written to disk without being copied
-   first. A page CAN be written to disk without being copied first if and only
-   if its contents will not be modified or used at any time after userspace
-   processes are frozen. A page MUST be in pageset 1 if its contents are
-   modified or used at any time after userspace processes have been frozen.
-
-   Normally (ie if this option is enabled), TuxOnIce will put all pages on the
-   per-zone LRUs in pageset2, then remove those pages used by any userspace
-   user interface helper and TuxOnIce storage manager that are running,
-   together with pages used by the GEM memory manager introduced around 2.6.28
-   kernels.
-
-   If this option is disabled, a much more conservative approach will be taken.
-   The only pages in pageset2 will be those belonging to userspace processes,
-   with the exclusion of those belonging to the TuxOnIce userspace helpers
-   mentioned above. This will result in a much smaller pageset2, and will
-   therefore result in smaller images than are possible with this option
-   enabled.
-
-   - ignore_rootfs
-
-   TuxOnIce records which device is mounted as the root filesystem when
-   writing the hibernation image. It will normally check at resume time that
-   this device isn't already mounted - that would be a cause of filesystem
-   corruption. In some particular cases (RAM based root filesystems), you
-   might want to disable this check. This option allows you to do that.
-
-   - image_exists:
-
-   Can be used in a script to determine whether a valid image exists at the
-   location currently pointed to by resume=. Returns up to three lines.
-   The first is whether an image exists (-1 for unsure, otherwise 0 or 1).
-   If an image eixsts, additional lines will return the machine and version.
-   Echoing anything to this entry removes any current image.
-
-   - image_size_limit:
-
-   The maximum size of hibernation image written to disk, measured in megabytes
-   (1024*1024).
-
-   - last_result:
-
-   The result of the last hibernation cycle, as defined in
-   include/linux/suspend-debug.h with the values SUSPEND_ABORTED to
-   SUSPEND_KEPT_IMAGE. This is a bitmask.
-
-   - late_cpu_hotplug:
-
-   This sysfs entry controls whether cpu hotplugging is done - as normal - just
-   before (unplug) and after (replug) the atomic copy/restore (so that all
-   CPUs/cores are available for multithreaded I/O). The alternative is to
-   unplug all secondary CPUs/cores at the start of hibernating/resuming, and
-   replug them at the end of resuming. No multithreaded I/O will be possible in
-   this configuration, but the odd machine has been reported to require it.
-
-   - lid_file:
-
-   This determines which ACPI button file we look in to determine whether the
-   lid is open or closed after resuming from suspend to disk or power off.
-   If the entry is set to "lid/LID", we'll open /proc/acpi/button/lid/LID/state
-   and check its contents at the appropriate moment. See post_wake_state below
-   for more details on how this entry is used.
-
-   - log_everything (CONFIG_PM_DEBUG):
-
-   Setting this option results in all messages printed being logged. Normally,
-   only a subset are logged, so as to not slow the process and not clutter the
-   logs. Useful for debugging. It can be toggled during a cycle by pressing
-   'L'.
-
-   - no_load_direct:
-
-   This is a debugging option. If, when loading the atomically copied pages of
-   an image, TuxOnIce finds that the destination address for a page is free,
-   it will normally allocate the image, load the data directly into that
-   address and skip it in the atomic restore. If this option is disabled, the
-   page will be loaded somewhere else and atomically restored like other pages.
-
-   - no_flusher_thread:
-
-   When doing multithreaded I/O (see below), the first online CPU can be used
-   to _just_ submit compressed pages when writing the image, rather than
-   compressing and submitting data. This option is normally disabled, but has
-   been included because Nigel would like to see whether it will be more useful
-   as the number of cores/cpus in computers increases.
-
-   - no_multithreaded_io:
-
-   TuxOnIce will normally create one thread per cpu/core on your computer,
-   each of which will then perform I/O. This will generally result in
-   throughput that's the maximum the storage medium can handle. There
-   shouldn't be any reason to disable multithreaded I/O now, but this option
-   has been retained for debugging purposes.
-
-   - no_pageset2
-
-   See the entry for full_pageset2 above for an explanation of pagesets.
-   Enabling this option causes TuxOnIce to do an atomic copy of all pages,
-   thereby limiting the maximum image size to 1/2 of memory, as swsusp does.
-
-   - no_pageset2_if_unneeded
-
-   See the entry for full_pageset2 above for an explanation of pagesets.
-   Enabling this option causes TuxOnIce to act like no_pageset2 was enabled
-   if and only it isn't needed anyway. This option may still make TuxOnIce
-   less reliable because pageset2 pages are normally used to store the
-   atomic copy - drivers that want to do allocations of larger amounts of
-   memory in one shot will be more likely to find that those amounts aren't
-   available if this option is enabled.
-
-   - pause_between_steps (CONFIG_PM_DEBUG):
-
-   This option is used during debugging, to make TuxOnIce pause between
-   each step of the process. It is ignored when the nice display is on.
-
-   - post_wake_state:
-
-   TuxOnIce provides support for automatically waking after a user-selected
-   delay, and using a different powerdown method if the lid is still closed.
-   (Yes, we're assuming a laptop).  This entry lets you choose what state
-   should be entered next. The values are those described under
-   powerdown_method, below. It can be used to suspend to RAM after hibernating,
-   then powerdown properly (say) 20 minutes. It can also be used to power down
-   properly, then wake at (say) 6.30am and suspend to RAM until you're ready
-   to use the machine.
-
-   - powerdown_method:
-
-   Used to select a method by which TuxOnIce should powerdown after writing the
-   image. Currently:
-
-   0: Don't use ACPI to power off.
-   3: Attempt to enter Suspend-to-ram.
-   4: Attempt to enter ACPI S4 mode.
-   5: Attempt to power down via ACPI S5 mode.
-
-   Note that these options are highly dependant upon your hardware & software:
-
-   3: When succesful, your machine suspends to ram instead of powering off.
-      The advantage of using this mode is that it doesn't matter whether your
-      battery has enough charge to make it through to your next resume. If it
-      lasts, you will simply resume from suspend to ram (and the image on disk
-      will be discarded). If the battery runs out, you will resume from disk
-      instead. The disadvantage is that it takes longer than a normal
-      suspend-to-ram to enter the state, since the suspend-to-disk image needs
-      to be written first.
-   4/5: When successful, your machine will be off and comsume (almost) no power.
-      But it might still react to some external events like opening the lid or
-      trafic on  a network or usb device. For the bios, resume is then the same
-      as warm boot, similar to a situation where you used the command `reboot'
-      to reboot your machine. If your machine has problems on warm boot or if
-      you want to protect your machine with the bios password, this is probably
-      not the right choice. Mode 4 may be necessary on some machines where ACPI
-      wake up methods need to be run to properly reinitialise hardware after a
-      hibernation cycle.
-   0: Switch the machine completely off. The only possible wakeup is the power
-      button. For the bios, resume is then the same as a cold boot, in
-      particular you would  have to provide your bios boot password if your
-      machine uses that feature for booting.
-
-   - progressbar_granularity_limit:
-
-   This option can be used to limit the granularity of the progress bar
-   displayed with a bootsplash screen. The value is the maximum number of
-   steps. That is, 10 will make the progress bar jump in 10% increments.
-
-   - reboot:
-
-   This option causes TuxOnIce to reboot rather than powering down
-   at the end of saving an image. It can be toggled during a cycle by pressing
-   'R'.
-
-   - resume:
-
-   This sysfs entry can be used to read and set the location in which TuxOnIce
-   will look for the signature of an image - the value set using resume= at
-   boot time or CONFIG_PM_STD_PARTITION ("Default resume partition"). By
-   writing to this file as well as modifying your bootloader's configuration
-   file (eg menu.lst), you can set or reset the location of your image or the
-   method of storing the image without rebooting.
-
-   - replace_swsusp (CONFIG_TOI_REPLACE_SWSUSP):
-
-   This option makes
-
-     echo disk > /sys/power/state
-
-   activate TuxOnIce instead of swsusp. Regardless of whether this option is
-   enabled, any invocation of swsusp's resume time trigger will cause TuxOnIce
-   to check for an image too. This is due to the fact that at resume time, we
-   can't know whether this option was enabled until we see if an image is there
-   for us to resume from. (And when an image exists, we don't care whether we
-   did replace swsusp anyway - we just want to resume).
-
-   - resume_commandline:
-
-   This entry can be read after resuming to see the commandline that was used
-   when resuming began. You might use this to set up two bootloader entries
-   that are the same apart from the fact that one includes a extra append=
-   argument "at_work=1". You could then grep resume_commandline in your
-   post-resume scripts and configure networking (for example) differently
-   depending upon whether you're at home or work. resume_commandline can be
-   set to arbitrary text if you wish to remove sensitive contents.
-
-   - swap/swapfilename:
-
-   This entry is used to specify the swapfile or partition that
-   TuxOnIce will attempt to swapon/swapoff automatically. Thus, if
-   I normally use /dev/hda1 for swap, and want to use /dev/hda2 for specifically
-   for my hibernation image, I would
-
-   echo /dev/hda2 > /sys/power/tuxonice/swap/swapfile
-
-   /dev/hda2 would then be automatically swapon'd and swapoff'd. Note that the
-   swapon and swapoff occur while other processes are frozen (including kswapd)
-   so this swap file will not be used up when attempting to free memory. The
-   parition/file is also given the highest priority, so other swapfiles/partitions
-   will only be used to save the image when this one is filled.
-
-   The value of this file is used by headerlocations along with any currently
-   activated swapfiles/partitions.
-
-   - swap/headerlocations:
-
-   This option tells you the resume= options to use for swap devices you
-   currently have activated. It is particularly useful when you only want to
-   use a swap file to store your image. See above for further details.
-
-   - test_bio
-
-   This is a debugging option. When enabled, TuxOnIce will not hibernate.
-   Instead, when asked to write an image, it will skip the atomic copy,
-   just doing the writing of the image and then returning control to the
-   user at the point where it would have powered off. This is useful for
-   testing throughput in different configurations.
-
-   - test_filter_speed
-
-   This is a debugging option. When enabled, TuxOnIce will not hibernate.
-   Instead, when asked to write an image, it will not write anything or do
-   an atomic copy, but will only run any enabled compression algorithm on the
-   data that would have been written (the source pages of the atomic copy in
-   the case of pageset 1). This is useful for comparing the performance of
-   compression algorithms and for determining the extent to which an upgrade
-   to your storage method would improve hibernation speed.
-
-   - user_interface/debug_sections (CONFIG_PM_DEBUG):
-
-   This value, together with the console log level, controls what debugging
-   information is displayed. The console log level determines the level of
-   detail, and this value determines what detail is displayed. This value is
-   a bit vector, and the meaning of the bits can be found in the kernel tree
-   in include/linux/tuxonice.h. It can be overridden using the kernel's
-   command line option suspend_dbg.
-
-   - user_interface/default_console_level (CONFIG_PM_DEBUG):
-
-   This determines the value of the console log level at the start of a
-   hibernation cycle. If debugging is compiled in, the console log level can be
-   changed during a cycle by pressing the digit keys. Meanings are:
-
-   0: Nice display.
-   1: Nice display plus numerical progress.
-   2: Errors only.
-   3: Low level debugging info.
-   4: Medium level debugging info.
-   5: High level debugging info.
-   6: Verbose debugging info.
-
-   - user_interface/enable_escape:
-
-   Setting this to "1" will enable you abort a hibernation cycle or resuming by
-   pressing escape, "0" (default) disables this feature. Note that enabling
-   this option means that you cannot initiate a hibernation cycle and then walk
-   away from your computer, expecting it to be secure. With feature disabled,
-   you can validly have this expectation once TuxOnice begins to write the
-   image to disk. (Prior to this point, it is possible that TuxOnice might
-   about because of failure to freeze all processes or because constraints
-   on its ability to save the image are not met).
-
-   - user_interface/program
-
-   This entry is used to tell TuxOnice what userspace program to use for
-   providing a user interface while hibernating. The program uses a netlink
-   socket to pass messages back and forward to the kernel, allowing all of the
-   functions formerly implemented in the kernel user interface components.
-
-   - version:
-
-   The version of TuxOnIce you have compiled into the currently running kernel.
-
-   - wake_alarm_dir:
-
-   As mentioned above (post_wake_state), TuxOnIce supports automatically waking
-   after some delay. This entry allows you to select which wake alarm to use.
-   It should contain the value "rtc0" if you're wanting to use
-   /sys/class/rtc/rtc0.
-
-   - wake_delay:
-
-   This value determines the delay from the end of writing the image until the
-   wake alarm is triggered. You can set an absolute time by writing the desired
-   time into /sys/class/rtc/<wake_alarm_dir>/wakealarm and leaving these values
-   empty.
-
-   Note that for the wakeup to actually occur, you may need to modify entries
-   in /proc/acpi/wakeup. This is done by echoing the name of the button in the
-   first column (eg PBTN) into the file.
-
-7. How do you get support?
-
-   Glad you asked. TuxOnIce is being actively maintained and supported
-   by Nigel (the guy doing most of the kernel coding at the moment), Bernard
-   (who maintains the hibernate script and userspace user interface components)
-   and its users.
-
-   Resources availble include HowTos, FAQs and a Wiki, all available via
-   tuxonice.net.  You can find the mailing lists there.
-
-8. I think I've found a bug. What should I do?
-
-   By far and a way, the most common problems people have with TuxOnIce
-   related to drivers not having adequate power management support. In this
-   case, it is not a bug with TuxOnIce, but we can still help you. As we
-   mentioned above, such issues can usually be worked around by building the
-   functionality as modules and unloading them while hibernating. Please visit
-   the Wiki for up-to-date lists of known issues and work arounds.
-
-   If this information doesn't help, try running:
-
-   hibernate --bug-report
-
-   ..and sending the output to the users mailing list.
-
-   Good information on how to provide us with useful information from an
-   oops is found in the file REPORTING-BUGS, in the top level directory
-   of the kernel tree. If you get an oops, please especially note the
-   information about running what is printed on the screen through ksymoops.
-   The raw information is useless.
-
-9. When will XXX be supported?
-
-   If there's a feature missing from TuxOnIce that you'd like, feel free to
-   ask. We try to be obliging, within reason.
-
-   Patches are welcome. Please send to the list.
-
-10. How does it work?
-
-   TuxOnIce does its work in a number of steps.
-
-   a. Freezing system activity.
-
-   The first main stage in hibernating is to stop all other activity. This is
-   achieved in stages. Processes are considered in fours groups, which we will
-   describe in reverse order for clarity's sake: Threads with the PF_NOFREEZE
-   flag, kernel threads without this flag, userspace processes with the
-   PF_SYNCTHREAD flag and all other processes. The first set (PF_NOFREEZE) are
-   untouched by the refrigerator code. They are allowed to run during hibernating
-   and resuming, and are used to support user interaction, storage access or the
-   like. Other kernel threads (those unneeded while hibernating) are frozen last.
-   This leaves us with userspace processes that need to be frozen. When a
-   process enters one of the *_sync system calls, we set a PF_SYNCTHREAD flag on
-   that process for the duration of that call. Processes that have this flag are
-   frozen after processes without it, so that we can seek to ensure that dirty
-   data is synced to disk as quickly as possible in a situation where other
-   processes may be submitting writes at the same time. Freezing the processes
-   that are submitting data stops new I/O from being submitted. Syncthreads can
-   then cleanly finish their work. So the order is:
-
-   - Userspace processes without PF_SYNCTHREAD or PF_NOFREEZE;
-   - Userspace processes with PF_SYNCTHREAD (they won't have NOFREEZE);
-   - Kernel processes without PF_NOFREEZE.
-
-   b. Eating memory.
-
-   For a successful hibernation cycle, you need to have enough disk space to store the
-   image and enough memory for the various limitations of TuxOnIce's
-   algorithm. You can also specify a maximum image size. In order to attain
-   to those constraints, TuxOnIce may 'eat' memory. If, after freezing
-   processes, the constraints aren't met, TuxOnIce will thaw all the
-   other processes and begin to eat memory until its calculations indicate
-   the constraints are met. It will then freeze processes again and recheck
-   its calculations.
-
-   c. Allocation of storage.
-
-   Next, TuxOnIce allocates the storage that will be used to save
-   the image.
-
-   The core of TuxOnIce knows nothing about how or where pages are stored. We
-   therefore request the active allocator (remember you might have compiled in
-   more than one!) to allocate enough storage for our expect image size. If
-   this request cannot be fulfilled, we eat more memory and try again. If it
-   is fulfiled, we seek to allocate additional storage, just in case our
-   expected compression ratio (if any) isn't achieved. This time, however, we
-   just continue if we can't allocate enough storage.
-
-   If these calls to our allocator change the characteristics of the image
-   such that we haven't allocated enough memory, we also loop. (The allocator
-   may well need to allocate space for its storage information).
-
-   d. Write the first part of the image.
-
-   TuxOnIce stores the image in two sets of pages called 'pagesets'.
-   Pageset 2 contains pages on the active and inactive lists; essentially
-   the page cache. Pageset 1 contains all other pages, including the kernel.
-   We use two pagesets for one important reason: We need to make an atomic copy
-   of the kernel to ensure consistency of the image. Without a second pageset,
-   that would limit us to an image that was at most half the amount of memory
-   available. Using two pagesets allows us to store a full image. Since pageset
-   2 pages won't be needed in saving pageset 1, we first save pageset 2 pages.
-   We can then make our atomic copy of the remaining pages using both pageset 2
-   pages and any other pages that are free. While saving both pagesets, we are
-   careful not to corrupt the image. Among other things, we use lowlevel block
-   I/O routines that don't change the pagecache contents.
-
-   The next step, then, is writing pageset 2.
-
-   e. Suspending drivers and storing processor context.
-
-   Having written pageset2, TuxOnIce calls the power management functions to
-   notify drivers of the hibernation, and saves the processor state in preparation
-   for the atomic copy of memory we are about to make.
-
-   f. Atomic copy.
-
-   At this stage, everything else but the TuxOnIce code is halted. Processes
-   are frozen or idling, drivers are quiesced and have stored (ideally and where
-   necessary) their configuration in memory we are about to atomically copy.
-   In our lowlevel architecture specific code, we have saved the CPU state.
-   We can therefore now do our atomic copy before resuming drivers etc.
-
-   g. Save the atomic copy (pageset 1).
-
-   TuxOnice can then write the atomic copy of the remaining pages. Since we
-   have copied the pages into other locations, we can continue to use the
-   normal block I/O routines without fear of corruption our image.
-
-   f. Save the image header.
-
-   Nearly there! We save our settings and other parameters needed for
-   reloading pageset 1 in an 'image header'. We also tell our allocator to
-   serialise its data at this stage, so that it can reread the image at resume
-   time.
-
-   g. Set the image header.
-
-   Finally, we edit the header at our resume= location. The signature is
-   changed by the allocator to reflect the fact that an image exists, and to
-   point to the start of that data if necessary (swap allocator).
-
-   h. Power down.
-
-   Or reboot if we're debugging and the appropriate option is selected.
-
-   Whew!
-
-   Reloading the image.
-   --------------------
-
-   Reloading the image is essentially the reverse of all the above. We load
-   our copy of pageset 1, being careful to choose locations that aren't going
-   to be overwritten as we copy it back (We start very early in the boot
-   process, so there are no other processes to quiesce here). We then copy
-   pageset 1 back to its original location in memory and restore the process
-   context. We are now running with the original kernel. Next, we reload the
-   pageset 2 pages, free the memory and swap used by TuxOnIce, restore
-   the pageset header and restart processes. Sounds easy in comparison to
-   hibernating, doesn't it!
-
-   There is of course more to TuxOnIce than this, but this explanation
-   should be a good start. If there's interest, I'll write further
-   documentation on range pages and the low level I/O.
-
-11. Who wrote TuxOnIce?
-
-   (Answer based on the writings of Florent Chabaud, credits in files and
-   Nigel's limited knowledge; apologies to anyone missed out!)
-
-   The main developers of TuxOnIce have been...
-
-   Gabor Kuti
-   Pavel Machek
-   Florent Chabaud
-   Bernard Blackham
-   Nigel Cunningham
-
-   Significant portions of swsusp, the code in the vanilla kernel which
-   TuxOnIce enhances, have been worked on by Rafael Wysocki. Thanks should
-   also be expressed to him.
-
-   The above mentioned developers have been aided in their efforts by a host
-   of hundreds, if not thousands of testers and people who have submitted bug
-   fixes & suggestions. Of special note are the efforts of Michael Frank, who
-   had his computers repetitively hibernate and resume for literally tens of
-   thousands of cycles and developed scripts to stress the system and test
-   TuxOnIce far beyond the point most of us (Nigel included!) would consider
-   testing. His efforts have contributed as much to TuxOnIce as any of the
-   names above.

+MuQSS - The Multiple Queue Skiplist Scheduler by Con Kolivas.
+
+See sched-BFS.txt for basic design; MuQSS is a per-cpu runqueue variant with
+one 8 level skiplist per runqueue, and fine grained locking for much more
+scalability.
+
+Goals.
+
+The goal of the Multiple Queue Skiplist Scheduler, referred to as MuQSS from
+here on (pronounced mux) is to completely do away with the complex designs of
+the past for the cpu process scheduler and instead implement one that is very
+simple in basic design. The main focus of MuQSS is to achieve excellent desktop
+interactivity and responsiveness without heuristics and tuning knobs that are
+difficult to understand, impossible to model and predict the effect of, and when
+tuned to one workload cause massive detriment to another, while still being
+scalable to many CPUs and processes.
+
+
+Design summary.
+
+MuQSS is best described as per-cpu multiple runqueue, O(log n) insertion, O(1)
+lookup, earliest effective virtual deadline first design, loosely based on EEVDF
+(earliest eligible virtual deadline first) and my previous Staircase Deadline
+scheduler, and evolved from the single runqueue O(n) BFS scheduler. Each
+component shall be described in order to understand the significance of, and
+reasoning for it.
+
+
+Design reasoning.
+
+In BFS, the use of a single runqueue across all CPUs meant that each CPU would
+need to scan the entire runqueue looking for the process with the earliest
+deadline and schedule that next, regardless of which CPU it originally came
+from. This made BFS deterministic with respect to latency and provided
+guaranteed latencies dependent on number of processes and CPUs. The single
+runqueue, however, meant that all CPUs would compete for the single lock
+protecting it, which would lead to increasing lock contention as the number of
+CPUs rose and appeared to limit scalability of common workloads beyond 16
+logical CPUs. Additionally, the O(n) lookup of the runqueue list obviously
+increased overhead proportionate to the number of queued proecesses and led to
+cache thrashing while iterating over the linked list.
+
+MuQSS is an evolution of BFS, designed to maintain the same scheduling
+decision mechanism and be virtually deterministic without relying on the
+constrained design of the single runqueue by splitting out the single runqueue
+to be per-CPU and use skiplists instead of linked lists.
+
+The original reason for going back to a single runqueue design for BFS was that
+once multiple runqueues are introduced, per-CPU or otherwise, there will be
+complex interactions as each runqueue will be responsible for the scheduling
+latency and fairness of the tasks only on its own runqueue, and to achieve
+fairness and low latency across multiple CPUs, any advantage in throughput of
+having CPU local tasks causes other disadvantages. This is due to requiring a
+very complex balancing system to at best achieve some semblance of fairness
+across CPUs and can only maintain relatively low latency for tasks bound to the
+same CPUs, not across them. To increase said fairness and latency across CPUs,
+the advantage of local runqueue locking, which makes for better scalability, is
+lost due to having to grab multiple locks.
+
+MuQSS works around the problems inherent in multiple runqueue designs by
+making its skip lists priority ordered and through novel use of lockless
+examination of each other runqueue it can decide if it should take the earliest
+deadline task from another runqueue for latency reasons, or for CPU balancing
+reasons. It still does not have a balancing system, choosing to allow the
+next task scheduling decision and task wakeup CPU choice to allow balancing to
+happen by virtue of its choices.
+
+
+Design:
+
+MuQSS is an 8 level skip list per runqueue variant of BFS.
+
+See sched-BFS.txt for some of the shared design details.
+
+Documentation yet to be completed.

-
-1. Introduction
-
-	This is a driver for STMicroelectronics's CPiA2 (second generation
-Colour Processor Interface ASIC) based cameras. This camera outputs an MJPEG
-stream at up to vga size. It implements the Video4Linux interface as much as
-possible.  Since the V4L interface does not support compressed formats, only
-an mjpeg enabled application can be used with the camera. We have modified the
-gqcam application to view this stream.
-
-	The driver is implemented as two kernel modules. The cpia2 module
-contains the camera functions and the V4L interface.  The cpia2_usb module
-contains usb specific functions.  The main reason for this was the size of the
-module was getting out of hand, so I separated them.  It is not likely that
-there will be a parallel port version.
-
-FEATURES:
-   - Supports cameras with the Vision stv6410 (CIF) and stv6500 (VGA) cmos
-     sensors. I only have the vga sensor, so can't test the other.
-   - Image formats: VGA, QVGA, CIF, QCIF, and a number of sizes in between.
-     VGA and QVGA are the native image sizes for the VGA camera. CIF is done
-     in the coprocessor by scaling QVGA.  All other sizes are done by clipping.
-   - Palette: YCrCb, compressed with MJPEG.
-   - Some compression parameters are settable.
-   - Sensor framerate is adjustable (up to 30 fps CIF, 15 fps VGA).
-   - Adjust brightness, color, contrast while streaming.
-   - Flicker control settable for 50 or 60 Hz mains frequency.
-
-2. Making and installing the stv672 driver modules:
-
-	Requirements:
-	-------------
-	This should work with 2.4 (2.4.23 and later) and 2.6 kernels, but has
-only been tested on 2.6.  Video4Linux must be either compiled into the kernel or
-available as a module.  Video4Linux2 is automatically detected and made
-available at compile time.
-
-	Compiling:
-	----------
-	As root, do a make install.  This will compile and install the modules
-into the media/video directory in the module tree. For 2.4 kernels, use
-Makefile_2.4 (aka do make -f Makefile_2.4 install).
-
-	Setup:
-	------
-	Use 'modprobe cpia2' to load and 'modprobe -r cpia2' to unload. This
-may be done automatically by your distribution.
-
-3. Driver options
-
-	Option		Description
-	------		-----------
-	video_nr	video device to register (0=/dev/video0, etc)
-			range -1 to 64.  default is -1 (first available)
-			If you have more than 1 camera, this MUST be -1.
-	buffer_size	Size for each frame buffer in bytes (default 68k)
-	num_buffers	Number of frame buffers (1-32, default 3)
-	alternate	USB Alternate (2-7, default 7)
-	flicker_freq	Frequency for flicker reduction(50 or 60, default 60)
-	flicker_mode	0 to disable, or 1 to enable flicker reduction.
-			(default 0). This is only effective if the camera
-			uses a stv0672 coprocessor.
-
-	Setting the options:
-	--------------------
-	If you are using modules, edit /etc/modules.conf and add an options
-line like this:
-	options cpia2 num_buffers=3 buffer_size=65535
-
-	If the driver is compiled into the kernel, at boot time specify them
-like this:
-	cpia2.num_buffers=3 cpia2.buffer_size=65535
-
-	What buffer size should I use?
-	------------------------------
-	The maximum image size depends on the alternate you choose, and the
-frame rate achieved by the camera.  If the compression engine is able to
-keep up with the frame rate, the maximum image size is given by the table
-below.
-	The compression engine starts out at maximum compression, and will
-increase image quality until it is close to the size in the table.  As long
-as the compression engine can keep up with the frame rate, after a short time
-the images will all be about the size in the table, regardless of resolution.
-	At low alternate settings, the compression engine may not be able to
-compress the image enough and will reduce the frame rate by producing larger
-images.
-	The default of 68k should be good for most users.  This will handle
-any alternate at frame rates down to 15fps.  For lower frame rates, it may
-be necessary to increase the buffer size to avoid having frames dropped due
-to insufficient space.
-
-			     Image size(bytes)
-	Alternate  bytes/ms   15fps    30fps
-	    2         128      8533     4267
-	    3         384     25600    12800
-	    4         640     42667    21333
-	    5         768     51200    25600
-	    6         896     59733    29867
-	    7        1023     68200    34100
-
-	How many buffers should I use?
-	------------------------------
-	For normal streaming, 3 should give the best results.  With only 2,
-it is possible for the camera to finish sending one image just after a
-program has started reading the other.  If this happens, the driver must drop
-a frame.  The exception to this is if you have a heavily loaded machine.  In
-this case use 2 buffers.  You are probably not reading at the full frame rate.
-If the camera can send multiple images before a read finishes, it could
-overwrite the third buffer before the read finishes, leading to a corrupt
-image.  Single and double buffering have extra checks to avoid overwriting.
-
-4. Using the camera
-
-	We are providing a modified gqcam application to view the output. In
-order to avoid confusion, here it is called mview.  There is also the qx5view
-program which can also control the lights on the qx5 microscope. MJPEG Tools
-(http://mjpeg.sourceforge.net) can also be used to record from the camera.
-
-5. Notes to developers:
-
-   - This is a driver version stripped of the 2.4 back compatibility
-     and old MJPEG ioctl API. See cpia2.sf.net for 2.4 support.
-
-6. Thanks:
-
-   - Peter Pregler <Peter_Pregler@email.com>,
-     Scott J. Bertin <scottbertin@yahoo.com>, and
-     Jarl Totland <Jarl.Totland@bdc.no> for the original cpia driver, which
-     this one was modelled from.

-cx8800 release notes
-====================
-
-This is a v4l2 device driver for the cx2388x chip.
-
-
-current status
-==============
-
-video
-	- Basically works.
-	- For now, only capture and read(). Overlay isn't supported.
-
-audio
-	- The chip specs for the on-chip TV sound decoder are next
-	  to useless :-/
-	- Neverless the builtin TV sound decoder starts working now,
-	  at least for some standards.
-	  FOR ANY REPORTS ON THIS PLEASE MENTION THE TV NORM YOU ARE
-	  USING.
-	- Most tuner chips do provide mono sound, which may or may not
-	  be useable depending on the board design.  With the Hauppauge
-	  cards it works, so there is mono sound available as fallback.
-	- audio data dma (i.e. recording without loopback cable to the
-	  sound card) is supported via cx88-alsa.
-
-vbi
-	- Code present. Works for NTSC closed caption. PAL and other
-	  TV norms may or may not work.
-
-
-how to add support for new cards
-================================
-
-The driver needs some config info for the TV cards.  This stuff is in
-cx88-cards.c.  If the driver doesn't work well you likely need a new
-entry for your card in that file.  Check the kernel log (using dmesg)
-to see whenever the driver knows your card or not.  There is a line
-like this one:
-
-	cx8800[0]: subsystem: 0070:3400, board: Hauppauge WinTV \
-		34xxx models [card=1,autodetected]
-
-If your card is listed as "board: UNKNOWN/GENERIC" it is unknown to
-the driver.  What to do then?
-
- (1) Try upgrading to the latest snapshot, maybe it has been added
-     meanwhile.
- (2) You can try to create a new entry yourself, have a look at
-     cx88-cards.c.  If that worked, mail me your changes as unified
-     diff ("diff -u").
- (3) Or you can mail me the config information.  I need at least the
-     following information to add the card:
-
-     * the PCI Subsystem ID ("0070:3400" from the line above,
-       "lspci -v" output is fine too).
-     * the tuner type used by the card.  You can try to find one by
-       trial-and-error using the tuner=<n> insmod option.  If you
-       know which one the card has you can also have a look at the
-       list in CARDLIST.tuner
-
-Have fun,
-
-  Gerd

-
- Functional partitioning
- -----------------------
-
- Consists of the following (in the same order as the list under file
- partitioning):-
-
- 1. V4L2 display driver
-    Implements creation of video2 and video3 device nodes and
-    provides v4l2 device interface to manage VID0 and VID1 layers.
-
- 2. Display controller
-    Loads up VENC, OSD and external encoders such as ths8200. It provides
-    a set of API calls to V4L2 drivers to set the output/standards
-    in the VENC or external sub devices. It also provides
-    a device object to access the services from OSD subdevice
-    using sub device ops. The connection of external encoders to VENC LCD
-    controller port is done at init time based on default output and standard
-    selection or at run time when application change the output through
-    V4L2 IOCTLs.
-
-    When connected to an external encoder, vpbe controller is also responsible
-    for setting up the interface between VENC and external encoders based on
-    board specific settings (specified in board-xxx-evm.c). This allows
-    interfacing external encoders such as ths8200. The setup_if_config()
-    is implemented for this as well as configure_venc() (part of the next patch)
-    API to set timings in VENC for a specific display resolution. As of this
-    patch series, the interconnection and enabling and setting of the external
-    encoders is not present, and would be a part of the next patch series.
-
- 3. VENC subdevice module
-    Responsible for setting outputs provided through internal DACs and also
-    setting timings at LCD controller port when external encoders are connected
-    at the port or LCD panel timings required. When external encoder/LCD panel
-    is connected, the timings for a specific standard/preset is retrieved from
-    the board specific table and the values are used to set the timings in
-    venc using non-standard timing mode.
-
-    Support LCD Panel displays using the VENC. For example to support a Logic
-    PD display, it requires setting up the LCD controller port with a set of
-    timings for the resolution supported and setting the dot clock. So we could
-    add the available outputs as a board specific entry (i.e add the "LogicPD"
-    output name to board-xxx-evm.c). A table of timings for various LCDs
-    supported can be maintained in the board specific setup file to support
-    various LCD displays.As of this patch a basic driver is present, and this
-    support for external encoders and displays forms a part of the next
-    patch series.
-
- 4. OSD module
-    OSD module implements all OSD layer management and hardware specific
-    features. The VPBE module interacts with the OSD for enabling and
-    disabling appropriate features of the OSD.
-
- Current status:-
-
- A fully functional working version of the V4L2 driver is available. This
- driver has been tested with NTSC and PAL standards and buffer streaming.
-
- Following are TBDs.
-
- vpbe display controller
-    - Add support for external encoders.
-    - add support for selecting external encoder as default at probe time.
-
- vpbe venc sub device
-    - add timings for supporting ths8200
-    - add support for LogicPD LCD.
-
- FB drivers
-    - Add support for fbdev drivers.- Ready and part of subsequent patches.

-infrared remote control support in video4linux drivers
-======================================================
-
-
-basics
-------
-
-Current versions use the linux input layer to support infrared
-remote controls.  I suggest to download my input layer tools
-from http://bytesex.org/snapshot/input-<date>.tar.gz
-
-Modules you have to load:
-
-  saa7134	statically built in, i.e. just the driver :)
-  bttv		ir-kbd-gpio or ir-kbd-i2c depending on your
-		card.
-
-ir-kbd-gpio and ir-kbd-i2c don't support all cards lirc supports
-(yet), mainly for the reason that the code of lirc_i2c and lirc_gpio
-was very confusing and I decided to basically start over from scratch.
-Feel free to contact me in case of trouble.  Note that the ir-kbd-*
-modules work on 2.6.x kernels only through ...
-
-
-how it works
-------------
-
-The modules register the remote as keyboard within the linux input
-layer, i.e. you'll see the keys of the remote as normal key strokes
-(if CONFIG_INPUT_KEYBOARD is enabled).
-
-Using the event devices (CONFIG_INPUT_EVDEV) it is possible for
-applications to access the remote via /dev/input/event<n> devices.
-You might have to create the special files using "/sbin/MAKEDEV
-input".  The input layer tools mentioned above use the event device.
-
-The input layer tools are nice for trouble shooting, i.e. to check
-whenever the input device is really present, which of the devices it
-is, check whenever pressing keys on the remote actually generates
-events and the like.  You can also use the kbd utility to change the
-keymaps (2.6.x kernels only through).
-
-
-using with lircd
-================
-
-The cvs version of the lircd daemon supports reading events from the
-linux input layer (via event device).  The input layer tools tarball
-comes with a lircd config file.
-
-
-using without lircd
-===================
-
-XFree86 likely can be configured to recognise the remote keys.  Once I
-simply tried to configure one of the multimedia keyboards as input
-device, which had the effect that XFree86 recognised some of the keys
-of my remote control and passed volume up/down key presses as
-XF86AudioRaiseVolume and XF86AudioLowerVolume key events to the X11
-clients.
-
-It likely is possible to make that fly with a nice xkb config file,
-I know next to nothing about that through.
-
-
-Have fun,
-
-  Gerd

-==================
-
-This is a v4l2 device driver for the Conexant cx23415/6 MPEG encoder/decoder.
-The cx23415 can do both encoding and decoding, the cx23416 can only do MPEG
-encoding. Currently the only card featuring full decoding support is the
-Hauppauge PVR-350.
-
-NOTE: this driver requires the latest encoder firmware (version 2.06.039, size
-376836 bytes). Get the firmware from here:
-
-http://dl.ivtvdriver.org/ivtv/firmware/
-
-NOTE: 'normal' TV applications do not work with this driver, you need
-an application that can handle MPEG input such as mplayer, xine, MythTV,
-etc.
-
-The primary goal of the IVTV project is to provide a "clean room" Linux
-Open Source driver implementation for video capture cards based on the
-iCompression iTVC15 or Conexant CX23415/CX23416 MPEG Codec.
-
-Features:
- * Hardware mpeg2 capture of broadcast video (and sound) via the tuner or
-   S-Video/Composite and audio line-in.
- * Hardware mpeg2 capture of FM radio where hardware support exists
- * Supports NTSC, PAL, SECAM with stereo sound
- * Supports SAP and bilingual transmissions.
- * Supports raw VBI (closed captions and teletext).
- * Supports sliced VBI (closed captions and teletext) and is able to insert
-   this into the captured MPEG stream.
- * Supports raw YUV and PCM input.
-
-Additional features for the PVR-350 (CX23415 based):
- * Provides hardware mpeg2 playback
- * Provides comprehensive OSD (On Screen Display: ie. graphics overlaying the
-   video signal)
- * Provides a framebuffer (allowing X applications to appear on the video
-   device)
- * Supports raw YUV output.
-

-
-Devices
-=======
-
-A maximum of 12 ivtv boards are allowed at the moment.
-
-Cards that don't have a video output capability (i.e. non PVR350 cards)
-lack the vbi8, vbi16, video16 and video48 devices. They also do not
-support the framebuffer device /dev/fbx for OSD.
-
-The radio0 device may or may not be present, depending on whether the
-card has a radio tuner or not.
-
-Here is a list of the base v4l devices:
-crw-rw----    1 root     video     81,   0 Jun 19 22:22 /dev/video0
-crw-rw----    1 root     video     81,  16 Jun 19 22:22 /dev/video16
-crw-rw----    1 root     video     81,  24 Jun 19 22:22 /dev/video24
-crw-rw----    1 root     video     81,  32 Jun 19 22:22 /dev/video32
-crw-rw----    1 root     video     81,  48 Jun 19 22:22 /dev/video48
-crw-rw----    1 root     video     81,  64 Jun 19 22:22 /dev/radio0
-crw-rw----    1 root     video     81, 224 Jun 19 22:22 /dev/vbi0
-crw-rw----    1 root     video     81, 228 Jun 19 22:22 /dev/vbi8
-crw-rw----    1 root     video     81, 232 Jun 19 22:22 /dev/vbi16
-
-Base devices
-============
-
-For every extra card you have the numbers increased by one. For example,
-/dev/video0 is listed as the 'base' encoding capture device so we have:
-
- /dev/video0  is the encoding capture device for the first card (card 0)
- /dev/video1  is the encoding capture device for the second card (card 1)
- /dev/video2  is the encoding capture device for the third card (card 2)
-
-Note that if the first card doesn't have a feature (eg no decoder, so no
-video16, the second card will still use video17. The simple rule is 'add
-the card number to the base device number'. If you have other capture
-cards (e.g. WinTV PCI) that are detected first, then you have to tell
-the ivtv module about it so that it will start counting at 1 (or 2, or
-whatever). Otherwise the device numbers can get confusing. The ivtv
-'ivtv_first_minor' module option can be used for that.
-
-
-/dev/video0
-The encoding capture device(s).
-Read-only.
-
-Reading from this device gets you the MPEG1/2 program stream.
-Example:
-
-cat /dev/video0 > my.mpg (you need to hit ctrl-c to exit)
-
-
-/dev/video16
-The decoder output device(s)
-Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
-
-An mpeg2 stream sent to this device will appear on the selected video
-display, audio will appear on the line-out/audio out.  It is only
-available for cards that support video out. Example:
-
-cat my.mpg >/dev/video16
-
-
-/dev/video24
-The raw audio capture device(s).
-Read-only
-
-The raw audio PCM stereo stream from the currently selected
-tuner or audio line-in.  Reading from this device results in a raw
-(signed 16 bit Little Endian, 48000 Hz, stereo pcm) capture.
-This device only captures audio. This should be replaced by an ALSA
-device in the future.
-Note that there is no corresponding raw audio output device, this is
-not supported in the decoder firmware.
-
-
-/dev/video32
-The raw video capture device(s)
-Read-only
-
-The raw YUV video output from the current video input. The YUV format
-is non-standard (V4L2_PIX_FMT_HM12).
-
-Note that the YUV and PCM streams are not synchronized, so they are of
-limited use.
-
-
-/dev/video48
-The raw video display device(s)
-Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
-
-Writes a YUV stream to the decoder of the card.
-
-
-/dev/radio0
-The radio tuner device(s)
-Cannot be read or written.
-
-Used to enable the radio tuner and tune to a frequency. You cannot
-read or write audio streams with this device.  Once you use this
-device to tune the radio, use /dev/video24 to read the raw pcm stream
-or /dev/video0 to get an mpeg2 stream with black video.
-
-
-/dev/vbi0
-The 'vertical blank interval' (Teletext, CC, WSS etc) capture device(s)
-Read-only
-
-Captures the raw (or sliced) video data sent during the Vertical Blank
-Interval. This data is used to encode teletext, closed captions, VPS,
-widescreen signalling, electronic program guide information, and other
-services.
-
-
-/dev/vbi8
-Processed vbi feedback device(s)
-Read-only. Only present if the MPEG decoder (i.e. CX23415) exists.
-
-The sliced VBI data embedded in an MPEG stream is reproduced on this
-device. So while playing back a recording on /dev/video16, you can
-read the embedded VBI data from /dev/vbi8.
-
-
-/dev/vbi16
-The vbi 'display' device(s)
-Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
-
-Can be used to send sliced VBI data to the video-out connector.

-			    pvrusb2 driver
-
-Background:
-
-  This driver is intended for the "Hauppauge WinTV PVR USB 2.0", which
-  is a USB 2.0 hosted TV Tuner.  This driver is a work in progress.
-  Its history started with the reverse-engineering effort by Björn
-  Danielsson <pvrusb2@dax.nu> whose web page can be found here:
-
-    http://pvrusb2.dax.nu/
-
-  From there Aurelien Alleaume <slts@free.fr> began an effort to
-  create a video4linux compatible driver.  I began with Aurelien's
-  last known snapshot and evolved the driver to the state it is in
-  here.
-
-  More information on this driver can be found at:
-
-    http://www.isely.net/pvrusb2.html
-
-
-  This driver has a strong separation of layers.  They are very
-  roughly:
-
-  1a. Low level wire-protocol implementation with the device.
-
-  1b. I2C adaptor implementation and corresponding I2C client drivers
-      implemented elsewhere in V4L.
-
-  1c. High level hardware driver implementation which coordinates all
-      activities that ensure correct operation of the device.
-
-  2.  A "context" layer which manages instancing of driver, setup,
-      tear-down, arbitration, and interaction with high level
-      interfaces appropriately as devices are hotplugged in the
-      system.
-
-  3.  High level interfaces which glue the driver to various published
-      Linux APIs (V4L, sysfs, maybe DVB in the future).
-
-  The most important shearing layer is between the top 2 layers.  A
-  lot of work went into the driver to ensure that any kind of
-  conceivable API can be laid on top of the core driver.  (Yes, the
-  driver internally leverages V4L to do its work but that really has
-  nothing to do with the API published by the driver to the outside
-  world.)  The architecture allows for different APIs to
-  simultaneously access the driver.  I have a strong sense of fairness
-  about APIs and also feel that it is a good design principle to keep
-  implementation and interface isolated from each other.  Thus while
-  right now the V4L high level interface is the most complete, the
-  sysfs high level interface will work equally well for similar
-  functions, and there's no reason I see right now why it shouldn't be
-  possible to produce a DVB high level interface that can sit right
-  alongside V4L.
-
-  NOTE: Complete documentation on the pvrusb2 driver is contained in
-  the html files within the doc directory; these are exactly the same
-  as what is on the web site at the time.  Browse those files
-  (especially the FAQ) before asking questions.
-
-
-Building
-
-  To build these modules essentially amounts to just running "Make",
-  but you need the kernel source tree nearby and you will likely also
-  want to set a few controlling environment variables first in order
-  to link things up with that source tree.  Please see the Makefile
-  here for comments that explain how to do that.
-
-
-Source file list / functional overview:
-
-  (Note: The term "module" used below generally refers to loosely
-  defined functional units within the pvrusb2 driver and bears no
-  relation to the Linux kernel's concept of a loadable module.)
-
-  pvrusb2-audio.[ch] - This is glue logic that resides between this
-    driver and the msp3400.ko I2C client driver (which is found
-    elsewhere in V4L).
-
-  pvrusb2-context.[ch] - This module implements the context for an
-    instance of the driver.  Everything else eventually ties back to
-    or is otherwise instanced within the data structures implemented
-    here.  Hotplugging is ultimately coordinated here.  All high level
-    interfaces tie into the driver through this module.  This module
-    helps arbitrate each interface's access to the actual driver core,
-    and is designed to allow concurrent access through multiple
-    instances of multiple interfaces (thus you can for example change
-    the tuner's frequency through sysfs while simultaneously streaming
-    video through V4L out to an instance of mplayer).
-
-  pvrusb2-debug.h - This header defines a printk() wrapper and a mask
-    of debugging bit definitions for the various kinds of debug
-    messages that can be enabled within the driver.
-
-  pvrusb2-debugifc.[ch] - This module implements a crude command line
-    oriented debug interface into the driver.  Aside from being part
-    of the process for implementing manual firmware extraction (see
-    the pvrusb2 web site mentioned earlier), probably I'm the only one
-    who has ever used this.  It is mainly a debugging aid.
-
-  pvrusb2-eeprom.[ch] - This is glue logic that resides between this
-    driver the tveeprom.ko module, which is itself implemented
-    elsewhere in V4L.
-
-  pvrusb2-encoder.[ch] - This module implements all protocol needed to
-    interact with the Conexant mpeg2 encoder chip within the pvrusb2
-    device.  It is a crude echo of corresponding logic in ivtv,
-    however the design goals (strict isolation) and physical layer
-    (proxy through USB instead of PCI) are enough different that this
-    implementation had to be completely different.
-
-  pvrusb2-hdw-internal.h - This header defines the core data structure
-    in the driver used to track ALL internal state related to control
-    of the hardware.  Nobody outside of the core hardware-handling
-    modules should have any business using this header.  All external
-    access to the driver should be through one of the high level
-    interfaces (e.g. V4L, sysfs, etc), and in fact even those high
-    level interfaces are restricted to the API defined in
-    pvrusb2-hdw.h and NOT this header.
-
-  pvrusb2-hdw.h - This header defines the full internal API for
-    controlling the hardware.  High level interfaces (e.g. V4L, sysfs)
-    will work through here.
-
-  pvrusb2-hdw.c - This module implements all the various bits of logic
-    that handle overall control of a specific pvrusb2 device.
-    (Policy, instantiation, and arbitration of pvrusb2 devices fall
-    within the jurisdiction of pvrusb-context not here).
-
-  pvrusb2-i2c-chips-*.c - These modules implement the glue logic to
-    tie together and configure various I2C modules as they attach to
-    the I2C bus.  There are two versions of this file.  The "v4l2"
-    version is intended to be used in-tree alongside V4L, where we
-    implement just the logic that makes sense for a pure V4L
-    environment.  The "all" version is intended for use outside of
-    V4L, where we might encounter other possibly "challenging" modules
-    from ivtv or older kernel snapshots (or even the support modules
-    in the standalone snapshot).
-
-  pvrusb2-i2c-cmd-v4l1.[ch] - This module implements generic V4L1
-    compatible commands to the I2C modules.  It is here where state
-    changes inside the pvrusb2 driver are translated into V4L1
-    commands that are in turn send to the various I2C modules.
-
-  pvrusb2-i2c-cmd-v4l2.[ch] - This module implements generic V4L2
-    compatible commands to the I2C modules.  It is here where state
-    changes inside the pvrusb2 driver are translated into V4L2
-    commands that are in turn send to the various I2C modules.
-
-  pvrusb2-i2c-core.[ch] - This module provides an implementation of a
-    kernel-friendly I2C adaptor driver, through which other external
-    I2C client drivers (e.g. msp3400, tuner, lirc) may connect and
-    operate corresponding chips within the pvrusb2 device.  It is
-    through here that other V4L modules can reach into this driver to
-    operate specific pieces (and those modules are in turn driven by
-    glue logic which is coordinated by pvrusb2-hdw, doled out by
-    pvrusb2-context, and then ultimately made available to users
-    through one of the high level interfaces).
-
-  pvrusb2-io.[ch] - This module implements a very low level ring of
-    transfer buffers, required in order to stream data from the
-    device.  This module is *very* low level.  It only operates the
-    buffers and makes no attempt to define any policy or mechanism for
-    how such buffers might be used.
-
-  pvrusb2-ioread.[ch] - This module layers on top of pvrusb2-io.[ch]
-    to provide a streaming API usable by a read() system call style of
-    I/O.  Right now this is the only layer on top of pvrusb2-io.[ch],
-    however the underlying architecture here was intended to allow for
-    other styles of I/O to be implemented with additional modules, like
-    mmap()'ed buffers or something even more exotic.
-
-  pvrusb2-main.c - This is the top level of the driver.  Module level
-    and USB core entry points are here.  This is our "main".
-
-  pvrusb2-sysfs.[ch] - This is the high level interface which ties the
-    pvrusb2 driver into sysfs.  Through this interface you can do
-    everything with the driver except actually stream data.
-
-  pvrusb2-tuner.[ch] - This is glue logic that resides between this
-    driver and the tuner.ko I2C client driver (which is found
-    elsewhere in V4L).
-
-  pvrusb2-util.h - This header defines some common macros used
-    throughout the driver.  These macros are not really specific to
-    the driver, but they had to go somewhere.
-
-  pvrusb2-v4l2.[ch] - This is the high level interface which ties the
-    pvrusb2 driver into video4linux.  It is through here that V4L
-    applications can open and operate the driver in the usual V4L
-    ways.  Note that **ALL** V4L functionality is published only
-    through here and nowhere else.
-
-  pvrusb2-video-*.[ch] - This is glue logic that resides between this
-    driver and the saa711x.ko I2C client driver (which is found
-    elsewhere in V4L).  Note that saa711x.ko used to be known as
-    saa7115.ko in ivtv.  There are two versions of this; one is
-    selected depending on the particular saa711[5x].ko that is found.
-
-  pvrusb2.h - This header contains compile time tunable parameters
-    (and at the moment the driver has very little that needs to be
-    tuned).

-
-What is it?
-===========
-
-This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV
-boards.  See http://www.semiconductors.philips.com/pip/saa7134hl for a
-description.
-
-
-Status
-======
-
-Almost everything is working.  video, sound, tuner, radio, mpeg ts, ...
-
-As with bttv, card-specific tweaks are needed.  Check CARDLIST for a
-list of known TV cards and saa7134-cards.c for the drivers card
-configuration info.
-
-
-Build
-=====
-
-Pick up videodev + v4l2 patches from http://bytesex.org/patches/.
-Configure, build, install + boot the new kernel.  You'll need at least
-these config options:
-
-	CONFIG_I2C=m
-	CONFIG_VIDEO_DEV=m
-
-Type "make" to build the driver now.  "make install" installs the
-driver.  "modprobe saa7134" should load it.  Depending on the card you
-might have to pass card=<nr> as insmod option, check CARDLIST for
-valid choices.
-
-
-Changes / Fixes
-===============
-
-Please mail me unified diffs ("diff -u") with your changes, and don't
-forget to tell me what it changes / which problem it fixes / whatever
-it is good for ...
-
-
-Known Problems
-==============
-
-* The tuner for the flyvideos isn't detected automatically and the
-  default might not work for you depending on which version you have.
-  There is a tuner= insmod option to override the driver's default.
-
-Card Variations:
-================
-
-Cards can use either of these two crystals (xtal):
- - 32.11 MHz -> .audio_clock=0x187de7
- - 24.576MHz -> .audio_clock=0x200000
-(xtal * .audio_clock = 51539600)
-
-Some details about 30/34/35:
-
- - saa7130 - low-price chip, doesn't have mute, that is why all those
- cards should have .mute field defined in their tuner structure.
-
- - saa7134 - usual chip
-
- - saa7133/35 - saa7135 is probably a marketing decision, since all those
- chips identifies itself as 33 on pci.
-
-Credits
-=======
-
-andrew.stevens@philips.com + werner.leeb@philips.com for providing
-saa7134 hardware specs and sample board.

-Have fun,

-
-1.1 What the TV decoder can do an what not
-
-The best know TV standards are NTSC/PAL/SECAM. but for decoding a frame that
-information is not enough. There are several formats of the TV standards.
-And not every TV decoder is able to handle every format. Also the every
-combination is supported by the driver. There are currently 11 different
-tv broadcast formats all aver the world.
-
-The CCIR defines parameters needed for broadcasting the signal.
-The CCIR has defined different standards: A,B,D,E,F,G,D,H,I,K,K1,L,M,N,...
-The CCIR says not much about the colorsystem used !!!
-And talking about a colorsystem says not to much about how it is broadcast.
-
-The CCIR standards A,E,F are not used any more.
-
-When you speak about NTSC, you usually mean the standard: CCIR - M using
-the NTSC colorsystem which is used in the USA, Japan, Mexico, Canada
-and a few others.
-
-When you talk about PAL, you usually mean: CCIR - B/G using the PAL
-colorsystem which is used in many Countries.
-
-When you talk about SECAM, you mean: CCIR - L using the SECAM Colorsystem
-which is used in France, and a few others.
-
-There the other version of SECAM, CCIR - D/K is used in Bulgaria, China,
-Slovakai, Hungary, Korea (Rep.), Poland, Rumania and a others.
-
-The CCIR - H uses the PAL colorsystem (sometimes SECAM) and is used in
-Egypt, Libya, Sri Lanka, Syrain Arab. Rep.
-
-The CCIR - I uses the PAL colorsystem, and is used in Great Britain, Hong Kong,
-Ireland, Nigeria, South Africa.
-
-The CCIR - N uses the PAL colorsystem and PAL frame size but the NTSC framerate,
-and is used in Argentinia, Uruguay, an a few others
-
-We do not talk about how the audio is broadcast !
-
-A rather good sites about the TV standards are:
-http://www.sony.jp/support/
-http://info.electronicwerkstatt.de/bereiche/fernsehtechnik/frequenzen_und_normen/Fernsehnormen/
-and http://www.cabl.com/restaurant/channel.html
-
-Other weird things around: NTSC 4.43 is a modificated NTSC, which is mainly
-used in PAL VCR's that are able to play back NTSC. PAL 60 seems to be the same
-as NTSC 4.43 . The Datasheets also talk about NTSC 44, It seems as if it would
-be the same as NTSC 4.43.
-NTSC Combs seems to be a decoder mode where the decoder uses a comb filter
-to split coma and luma instead of a Delay line.
-
-But I did not defiantly find out what NTSC Comb is.

-
-===========================
-
-1.2 What the TV encoder can do an what not
-
-The TV encoder are doing the "same" as the decoder, but in the oder direction.
-You feed them digital data and the generate a Composite or SVHS signal.
-For information about the colorsystems and TV norm take a look in the
-TV decoder section.
-
-Philips saa7185 TV Encoder
-was introduced in 1996, is used in the BUZ
-can generate: PAL B/G, NTSC M
-
-Brooktree bt856 TV Encoder
-was introduced in 1994, is used in the LML33
-can generate: PAL B/D/G/H/I/N, PAL M, NTSC M, PAL-N (Argentina)
-
-Analog Devices adv7170 TV Encoder
-was introduced in 2000, is used in the LML300R10
-can generate: PAL B/D/G/H/I/N, PAL M, NTSC M, PAL 60
-
-Analog Devices adv7175 TV Encoder
-was introduced in 1996, is used in the DC10, DC10+, DC10 old, DC30, DC30+
-can generate: PAL B/D/G/H/I/N, PAL M, NTSC M
-
-ITT mse3000 TV encoder
-was introduced in 1991, is used in the DC10 old
-can generate: PAL , NTSC , SECAM
-
-Conexant bt866 TV encoder
-is used in AVS6EYES, and
-can generate: NTSC/PAL, PAL­M, PAL­N
-
-The adv717x, should be able to produce PAL N. But you find nothing PAL N
-specific in the registers. Seem that you have to reuse a other standard
-to generate PAL N, maybe it would work if you use the PAL M settings.
-
-==========================
-
-2. How do I get this damn thing to work
-
-Load zr36067.o. If it can't autodetect your card, use the card=X insmod
-option with X being the card number as given in the previous section.
-To have more than one card, use card=X1[,X2[,X3,[X4[..]]]]
-
-To automate this, add the following to your /etc/modprobe.d/zoran.conf:
-
-options zr36067 card=X1[,X2[,X3[,X4[..]]]]
-alias char-major-81-0 zr36067
-
-One thing to keep in mind is that this doesn't load zr36067.o itself yet. It
-just automates loading. If you start using xawtv, the device won't load on
-some systems, since you're trying to load modules as a user, which is not
-allowed ("permission denied"). A quick workaround is to add 'Load "v4l"' to
-XF86Config-4 when you use X by default, or to run 'v4l-conf -c <device>' in
-one of your startup scripts (normally rc.local) if you don't use X. Both
-make sure that the modules are loaded on startup, under the root account.
-
-===========================
-
-3. What mainboard should I use (or why doesn't my card work)
-
-<insert lousy disclaimer here>. In short: good=SiS/Intel, bad=VIA.
-
-Experience tells us that people with a Buz, on average, have more problems
-than users with a DC10+/LML33. Also, it tells us that people owning a VIA-
-based mainboard (ktXXX, MVP3) have more problems than users with a mainboard
-based on a different chipset. Here's some notes from Andrew Stevens:
---
-Here's my experience of using LML33 and Buz on various motherboards:
-
-VIA MVP3
-	Forget it. Pointless. Doesn't work.
-Intel 430FX (Pentium 200)
-	LML33 perfect, Buz tolerable (3 or 4 frames dropped per movie)
-Intel 440BX (early stepping)
-	LML33 tolerable. Buz starting to get annoying (6-10 frames/hour)
-Intel 440BX (late stepping)
-	Buz tolerable, LML3 almost perfect (occasional single frame drops)
-SiS735
-	LML33 perfect, Buz tolerable.
-VIA KT133(*)
-	LML33 starting to get annoying, Buz poor enough that I have up.
-
-Both 440BX boards were dual CPU versions.
---
-Bernhard Praschinger later added:
---
-AMD 751
-	Buz perfect-tolerable
-AMD 760
-	Buz perfect-tolerable
---
-In general, people on the user mailinglist won't give you much of a chance
-if you have a VIA-based motherboard. They may be cheap, but sometimes, you'd
-rather want to spend some more money on better boards. In general, VIA
-mainboard's IDE/PCI performance will also suck badly compared to others.
-You'll noticed the DC10+/DC30+ aren't mentioned anywhere in the overview.
-Basically, you can assume that if the Buz works, the LML33 will work too. If
-the LML33 works, the DC10+/DC30+ will work too. They're most tolerant to
-different mainboard chipsets from all of the supported cards.
-
-If you experience timeouts during capture, buy a better mainboard or lower
-the quality/buffersize during capture (see 'Concerning buffer sizes, quality,
-output size etc.'). If it hangs, there's little we can do as of now. Check
-your IRQs and make sure the card has its own interrupts.
-
-===========================
-
-4. Programming interface
-
-This driver conforms to video4linux2. Support for V4L1 and for the custom
-zoran ioctls has been removed in kernel 2.6.38.
-
-For programming example, please, look at lavrec.c and lavplay.c code in
-the MJPEG-tools (http://mjpeg.sf.net/).
-
-Additional notes for software developers:
-
-   The driver returns maxwidth and maxheight parameters according to
-   the current TV standard (norm). Therefore, the software which
-   communicates with the driver and "asks" for these parameters should
-   first set the correct norm. Well, it seems logically correct: TV
-   standard is "more constant" for current country than geometry
-   settings of a variety of TV capture cards which may work in ITU or
-   square pixel format.
-
-===========================
-
-5. Applications
-
-Applications known to work with this driver:
-
-TV viewing:
-* xawtv
-* kwintv
-* probably any TV application that supports video4linux or video4linux2.
-
-MJPEG capture/playback:
-* mjpegtools/lavtools (or Linux Video Studio)
-* gstreamer
-* mplayer
-
-General raw capture:
-* xawtv
-* gstreamer
-* probably any application that supports video4linux or video4linux2
-
-Video editing:
-* Cinelerra
-* MainActor
-* mjpegtools (or Linux Video Studio)
-
-===========================
-
-6. Concerning buffer sizes, quality, output size etc.
-
-The zr36060 can do 1:2 JPEG compression. This is really the theoretical
-maximum that the chipset can reach. The driver can, however, limit compression
-to a maximum (size) of 1:4. The reason for this is that some cards (e.g. Buz)
-can't handle 1:2 compression without stopping capture after only a few minutes.
-With 1:4, it'll mostly work. If you have a Buz, use 'low_bitrate=1' to go into
-1:4 max. compression mode.
-
-100% JPEG quality is thus 1:2 compression in practice. So for a full PAL frame
-(size 720x576). The JPEG fields are stored in YUY2 format, so the size of the
-fields are 720x288x16/2 bits/field (2 fields/frame) = 207360 bytes/field x 2 =
-414720 bytes/frame (add some more bytes for headers and DHT (huffman)/DQT
-(quantization) tables, and you'll get to something like 512kB per frame for
-1:2 compression. For 1:4 compression, you'd have frames of half this size.
-
-Some additional explanation by Martin Samuelsson, which also explains the
-importance of buffer sizes:
---
-> Hmm, I do not think it is really that way. With the current (downloaded
-> at 18:00 Monday) driver I get that output sizes for 10 sec:
-> -q 50 -b 128 : 24.283.332 Bytes
-> -q 50 -b 256 : 48.442.368
-> -q 25 -b 128 : 24.655.992
-> -q 25 -b 256 : 25.859.820
-
-I woke up, and can't go to sleep again. I'll kill some time explaining why
-this doesn't look strange to me.
-
-Let's do some math using a width of 704 pixels. I'm not sure whether the Buz
-actually use that number or not, but that's not too important right now.
-
-704x288 pixels, one field, is 202752 pixels. Divided by 64 pixels per block;
-3168 blocks per field. Each pixel consist of two bytes; 128 bytes per block;
-1024 bits per block. 100% in the new driver mean 1:2 compression; the maximum
-output becomes 512 bits per block. Actually 510, but 512 is simpler to use
-for calculations.
-
-Let's say that we specify d1q50. We thus want 256 bits per block; times 3168
-becomes 811008 bits; 101376 bytes per field. We're talking raw bits and bytes
-here, so we don't need to do any fancy corrections for bits-per-pixel or such
-things. 101376 bytes per field.
-
-d1 video contains two fields per frame. Those sum up to 202752 bytes per
-frame, and one of those frames goes into each buffer.
-
-But wait a second! -b128 gives 128kB buffers! It's not possible to cram
-202752 bytes of JPEG data into 128kB!
-
-This is what the driver notice and automatically compensate for in your
-examples. Let's do some math using this information:
-
-128kB is 131072 bytes. In this buffer, we want to store two fields, which
-leaves 65536 bytes for each field. Using 3168 blocks per field, we get
-20.68686868... available bytes per block; 165 bits. We can't allow the
-request for 256 bits per block when there's only 165 bits available! The -q50
-option is silently overridden, and the -b128 option takes precedence, leaving
-us with the equivalence of -q32.
-
-This gives us a data rate of 165 bits per block, which, times 3168, sums up
-to 65340 bytes per field, out of the allowed 65536. The current driver has
-another level of rate limiting; it won't accept -q values that fill more than
-6/8 of the specified buffers. (I'm not sure why. "Playing it safe" seem to be
-a safe bet. Personally, I think I would have lowered requested-bits-per-block
-by one, or something like that.) We can't use 165 bits per block, but have to
-lower it again, to 6/8 of the available buffer space: We end up with 124 bits
-per block, the equivalence of -q24. With 128kB buffers, you can't use greater
-than -q24 at -d1. (And PAL, and 704 pixels width...)
-
-The third example is limited to -q24 through the same process. The second
-example, using very similar calculations, is limited to -q48. The only
-example that actually grab at the specified -q value is the last one, which
-is clearly visible, looking at the file size.
---
-
-Conclusion: the quality of the resulting movie depends on buffer size, quality,
-whether or not you use 'low_bitrate=1' as insmod option for the zr36060.c
-module to do 1:4 instead of 1:2 compression, etc.
-
-If you experience timeouts, lowering the quality/buffersize or using
-'low_bitrate=1 as insmod option for zr36060.o might actually help, as is
-proven by the Buz.
-
-===========================
-
-7. It hangs/crashes/fails/whatevers! Help!
-
-Make sure that the card has its own interrupts (see /proc/interrupts), check
-the output of dmesg at high verbosity (load zr36067.o with debug=2,
-load all other modules with debug=1). Check that your mainboard is favorable
-(see question 2) and if not, test the card in another computer. Also see the
-notes given in question 3 and try lowering quality/buffersize/capturesize
-if recording fails after a period of time.
-
-If all this doesn't help, give a clear description of the problem including
-detailed hardware information (memory+brand, mainboard+chipset+brand, which
-MJPEG card, processor, other PCI cards that might be of interest), give the
-system PnP information (/proc/interrupts, /proc/dma, /proc/devices), and give
-the kernel version, driver version, glibc version, gcc version and any other
-information that might possibly be of interest. Also provide the dmesg output
-at high verbosity. See 'Contacting' on how to contact the developers.

-    CPH06x: BT878 (w/o FM)
-    CPH07x: BT878 capture only
-
-  TV standards:
-     CPH0x0: NTSC-M/M

-  CPH03x was often sold as "TV capturer".
-
-  Identifying:
-  1) 878 cards can be identified by PCI Subsystem-ID:
-      144f:3000 = CPH06x
-      144F:3002 = CPH05x w/ FM
-      144F:3005 = CPH06x_LC (w/o remote control)
-  1) The cards have a sticker with "CPH"-model on the back.
-  2) These cards have a number printed on the PCB just above the tuner metal box:
-      "80-CP2000300-x" = CPH03X
-      "80-CP2000500-x" = CPH05X
-      "80-CP2000600-x" = CPH06X / CPH06x_LC
-
-  Askey sells these cards as "Magic TView series", Brand "MagicXpress".
-  Other OEM often call these "Tview", "TView99" or else.
-
-Lifeview Flyvideo Series:
--------------------------
-  The naming of these series differs in time and space.
-
-  Identifying:
-  1) Some models can be identified by PCI subsystem ID:
-      1852:1852 = Flyvideo 98 FM
-      1851:1850 = Flyvideo 98
-      1851:1851 = Flyvideo 98 EZ (capture only)
-  2) There is a print on the PCB:
-      LR25       = Flyvideo (Zoran ZR36120, SAA7110A)
-      LR26 Rev.N = Flyvideo II (Bt848)
-	   Rev.O = Flyvideo II (Bt878)
-      LR37 Rev.C = Flyvideo EZ (Capture only, ZR36120 + SAA7110)
-      LR38 Rev.A1= Flyvideo II EZ (Bt848 capture only)
-      LR50 Rev.Q = Flyvideo 98 (w/eeprom and PCI subsystem ID)
-	   Rev.W = Flyvideo 98 (no eeprom)
-      LR51 Rev.E = Flyvideo 98 EZ (capture only)
-      LR90       = Flyvideo 2000 (Bt878)
-		   Flyvideo 2000S (Bt878) w/Stereo TV (Package incl. LR91 daughterboard)
-      LR91       = Stereo daughter card for LR90
-      LR97       = Flyvideo DVBS
-      LR99 Rev.E = Low profile card for OEM integration (only internal audio!) bt878
-      LR136	 = Flyvideo 2100/3100 (Low profile, SAA7130/SAA7134)
-      LR137      = Flyvideo DV2000/DV3000 (SAA7130/SAA7134 + IEEE1394)
-      LR138 Rev.C= Flyvideo 2000 (SAA7130)
-		or Flyvideo 3000 (SAA7134) w/Stereo TV
-		   These exist in variations w/FM and w/Remote sometimes denoted
-		   by suffixes "FM" and "R".
-  3) You have a laptop (miniPCI card):
-      Product    = FlyTV Platinum Mini
-      Model/Chip = LR212/saa7135
-
-      Lifeview.com.tw states (Feb. 2002):
-      "The FlyVideo2000 and FlyVideo2000s product name have renamed to FlyVideo98."
-      Their Bt8x8 cards are listed as discontinued.
-      Flyvideo 2000S was probably sold as Flyvideo 3000 in some contries(Europe?).
-      The new Flyvideo 2000/3000 are SAA7130/SAA7134 based.
-
-  "Flyvideo II" had been the name for the 848 cards, nowadays (in Germany)
-  this name is re-used for LR50 Rev.W.
-  The Lifeview website mentioned Flyvideo III at some time, but such a card
-  has not yet been seen (perhaps it was the german name for LR90 [stereo]).
-  These cards are sold by many OEMs too.
-
-  FlyVideo A2 (Elta 8680)= LR90 Rev.F (w/Remote, w/o FM, stereo TV by tda9821) {Germany}
-  Lifeview 3000 (Elta 8681) as sold by Plus(April 2002), Germany = LR138 w/ saa7134

-This list tends to be outdated because it is updated manually ...
-
-==========================================================================
-
-bttv.o
-	the bt848/878 (grabber chip) driver
-
-	insmod args:
-		card=n		card type, see CARDLIST for a list.
-		tuner=n		tuner type, see CARDLIST for a list.
-		radio=0/1	card supports radio
-		pll=0/1/2	pll settings
-			0: don't use PLL
-			1: 28 MHz crystal installed
-			2: 35 MHz crystal installed
-
-		triton1=0/1     for Triton1 (+others) compatibility
-		vsfx=0/1	yet another chipset bug compatibility bit
-				see README.quirks for details on these two.
-
-		bigendian=n	Set the endianness of the gfx framebuffer.
-				Default is native endian.
-		fieldnr=0/1	Count fields.  Some TV descrambling software
-				needs this, for others it only generates
-				50 useless IRQs/sec.  default is 0 (off).
-		autoload=0/1	autoload helper modules (tuner, audio).
-				default is 1 (on).
-		bttv_verbose=0/1/2  verbose level (at insmod time, while
-				looking at the hardware).  default is 1.
-		bttv_debug=0/1	debug messages (for capture).
-				default is 0 (off).
-		irq_debug=0/1	irq handler debug messages.
-				default is 0 (off).
-		gbuffers=2-32	number of capture buffers for mmap'ed capture.
-				default is 4.
-		gbufsize=	size of capture buffers. default and
-				maximum value is 0x208000 (~2MB)
-		no_overlay=0	Enable overlay on broken hardware.  There
-				are some chipsets (SIS for example) which
-				are known to have problems with the PCI DMA
-				push used by bttv.  bttv will disable overlay
-				by default on this hardware to avoid crashes.
-				With this insmod option you can override this.
-		no_overlay=1	Disable overlay. It should be used by broken
-				hardware that doesn't support PCI2PCI direct
-				transfers.
-		automute=0/1	Automatically mutes the sound if there is
-				no TV signal, on by default.  You might try
-				to disable this if you have bad input signal
-				quality which leading to unwanted sound
-				dropouts.
-		chroma_agc=0/1	AGC of chroma signal, off by default.
-		adc_crush=0/1	Luminance ADC crush, on by default.
-		i2c_udelay=     Allow reduce I2C speed. Default is 5 usecs
-				(meaning 66,67 Kbps). The default is the
-				maximum supported speed by kernel bitbang
-				algorithm. You may use lower numbers, if I2C
-				messages are lost (16 is known to work on
-				all supported cards).
-
-		bttv_gpio=0/1
-		gpiomask=
-		audioall=
-		audiomux=
-				See Sound-FAQ for a detailed description.
-
-	remap, card, radio and pll accept up to four comma-separated arguments
-	(for multiple boards).
-
-tuner.o
-	The tuner driver.  You need this unless you want to use only
-	with a camera or external tuner ...
-
-	insmod args:
-		debug=1		print some debug info to the syslog
-		type=n		type of the tuner chip. n as follows:
-				see CARDLIST for a complete list.
-		pal=[bdgil]	select PAL variant (used for some tuners
-				only, important for the audio carrier).
-
-tvaudio.o
-	new, experimental module which is supported to provide a single
-	driver for all simple i2c audio control chips (tda/tea*).
-
-	insmod args:
-		tda8425  = 1	enable/disable the support for the
-		tda9840  = 1	various chips.
-		tda9850  = 1	The tea6300 can't be autodetected and is
-		tda9855  = 1	therefore off by default, if you have
-		tda9873  = 1	this one on your card (STB uses these)
-		tda9874a = 1	you have to enable it explicitly.
-		tea6300  = 0	The two tda985x chips use the same i2c
-		tea6420  = 1	address and can't be disturgished from
-		pic16c54 = 1	each other, you might have to disable
-				the wrong one.
-		debug = 1	print debug messages
-
-	insmod args for tda9874a:
-		tda9874a_SIF=1/2	select sound IF input pin (1 or 2)
-					(default is pin 1)
-		tda9874a_AMSEL=0/1	auto-mute select for NICAM (default=0)
-					Please read note 3 below!
-		tda9874a_STD=n		select TV sound standard (0..8):
-					0 - A2, B/G
-					1 - A2, M (Korea)
-					2 - A2, D/K (1)
-					3 - A2, D/K (2)
-					4 - A2, D/K (3)
-					5 - NICAM, I
-					6 - NICAM, B/G
-					7 - NICAM, D/K (default)
-					8 - NICAM, L
-
-	Note 1: tda9874a supports both tda9874h (old) and tda9874a (new) chips.
-	Note 2: tda9874h/a and tda9875 (which is supported separately by
-	tda9875.o) use the same i2c address so both modules should not be
-	used at the same time.
-	Note 3: Using tda9874a_AMSEL option depends on your TV card design!
-		AMSEL=0: auto-mute will switch between NICAM sound
-			 and the sound on 1st carrier (i.e. FM mono or AM).
-		AMSEL=1: auto-mute will switch between NICAM sound
-			 and the analog mono input (MONOIN pin).
-	If tda9874a decoder on your card has MONOIN pin not connected, then
-	use only tda9874_AMSEL=0 or don't specify this option at all.
-	For example:
-	  card=65 (FlyVideo 2000S) - set AMSEL=1 or AMSEL=0
-	  card=72 (Prolink PV-BT878P rev.9B) - set AMSEL=0 only
-
-msp3400.o
-	The driver for the msp34xx sound processor chips. If you have a
-	stereo card, you probably want to insmod this one.
-
-	insmod args:
-		debug=1/2	print some debug info to the syslog,
-				2 is more verbose.
-		simple=1	Use the "short programming" method.  Newer
-				msp34xx versions support this.  You need this
-				for dbx stereo.  Default is on if supported by
-				the chip.
-		once=1		Don't check the TV-stations Audio mode
-				every few seconds, but only once after
-				channel switches.
-		amsound=1	Audio carrier is AM/NICAM at 6.5 Mhz.  This
-				should improve things for french people, the
-				carrier autoscan seems to work with FM only...
-
-tea6300.o - OBSOLETE (use tvaudio instead)
-	The driver for the tea6300 fader chip.  If you have a stereo
-	card and the msp3400.o doesn't work, you might want to try this
-	one.  This chip is seen on most STB TV/FM cards (usually from
-	Gateway OEM sold surplus on auction sites).
-
-	insmod args:
-		debug=1		print some debug info to the syslog.
-
-tda8425.o - OBSOLETE (use tvaudio instead)
-	The driver for the tda8425 fader chip.  This driver used to be
-	part of bttv.c, so if your sound used to work but does not
-	anymore, try loading this module.
-
-	insmod args:
-		debug=1		print some debug info to the syslog.
-
-tda985x.o - OBSOLETE (use tvaudio instead)
-	The driver for the tda9850/55 audio chips.
-
-	insmod args:
-		debug=1		print some debug info to the syslog.
-		chip=9850/9855	set the chip type.

-- Start capturing by pressing "c" or by selecting it via a menu!!!
-
-- The memory of some S3 cards is not recognized right:
-
-  First of all, if you are not using XFree-3.2 or newer, upgrade AT LEAST to
-  XFree-3.2A! This solved the problem for most people.
-
-  Start up X11 like this: "XF86_S3 -probeonly" and write down where the
-  linear frame buffer is.
-  If it is different to the address found by bttv install bttv like this:
-  "insmod bttv vidmem=0xfb0"
-  if the linear frame buffer is at 0xfb000000 (i.e. omit the last 5 zeros!)
-
-  Some S3 cards even take up 64MB of memory but only report 32MB to the BIOS.
-  If this 64MB area overlaps the IO memory of the Bt848 you also have to
-  remap this. E.g.: insmod bttv vidmem=0xfb0 remap=0xfa0
-
-  If the video memory is found at the right place and there are no address
-  conflicts but still no picture (or the computer even crashes),
-  try disabling features of your PCI chipset in the BIOS setup.
-
-  Frank Kapahnke <frank@kapahnke.prima.ruhr.de> also reported that problems
-  with his S3 868 went away when he upgraded to XFree 3.2.
-
-
-- I still only get a black picture with my S3 card!
-
-  Even with XFree-3.2A some people have problems with their S3 cards
-  (mostly with Trio 64 but also with some others)
-  Get the free demo version of Accelerated X from www.xinside.com and try
-  bttv with it. bttv seems to work with most S3 cards with Accelerated X.
-
-  Since I do not know much (better make that almost nothing) about VGA card
-  programming I do not know the reason for this.
-  Looks like XFree does something different when setting up the video memory?
-  Maybe somebody can enlighten me?
-  Would be nice if somebody could get this to work with XFree since
-  Accelerated X costs more than some of the grabber cards ...
-
-  Better linear frame buffer support for S3 cards will probably be in
-  XFree 4.0.
-
-- Grabbing is not switched off when changing consoles with XFree.
-  That's because XFree and some AcceleratedX versions do not send unmap
-  events.
-
-- Some popup windows (e.g. of the window manager) are not refreshed.
-
-  Disable backing store by starting X with the option "-bs"
-
-- When using 32 bpp in XFree or 24+8bpp mode in AccelX 3.1 the system
-  can sometimes lock up if you use more than 1 bt848 card at the same time.
-  You will always get pixel errors when e.g. using more than 1 card in full
-  screen mode. Maybe we need something faster than the PCI bus ...
-
-
-- Some S3 cards and the Matrox Mystique will produce pixel errors with
-  full resolution in 32-bit mode.
-
-- Some video cards have problems with Accelerated X 4.1

-Release notes for bttv
-======================
-
-You'll need at least these config options for bttv:
-	CONFIG_I2C=m
-	CONFIG_I2C_ALGOBIT=m
-	CONFIG_VIDEO_DEV=m
-
-The latest bttv version is available from http://bytesex.org/bttv/
-
-
-Make bttv work with your card
------------------------------
-
-Just try "modprobe bttv" and see if that works.
-
-If it doesn't bttv likely could not autodetect your card and needs some
-insmod options.  The most important insmod option for bttv is "card=n"
-to select the correct card type.  If you get video but no sound you've
-very likely specified the wrong (or no) card type.  A list of supported
-cards is in CARDLIST.bttv
-
-If bttv takes very long to load (happens sometimes with the cheap
-cards which have no tuner), try adding this to your modules.conf:
-	options i2c-algo-bit bit_test=1
-
-/*(DEBLOBBED)*/
-
-If your card isn't listed in CARDLIST.bttv or if you have trouble making
-audio work, you should read the Sound-FAQ.
-
-
-Autodetecting cards
--------------------
-
-bttv uses the PCI Subsystem ID to autodetect the card type.  lspci lists
-the Subsystem ID in the second line, looks like this:
-
-00:0a.0 Multimedia video controller: Brooktree Corporation Bt878 (rev 02)
-	Subsystem: Hauppauge computer works Inc. WinTV/GO
-	Flags: bus master, medium devsel, latency 32, IRQ 5
-	Memory at e2000000 (32-bit, prefetchable) [size=4K]
-
-only bt878-based cards can have a subsystem ID (which does not mean
-that every card really has one).  bt848 cards can't have a Subsystem
-ID and therefore can't be autodetected.  There is a list with the ID's
-in bttv-cards.c (in case you are intrested or want to mail patches
-with updates).
-
-
-Still doesn't work?
--------------------
-
-I do NOT have a lab with 30+ different grabber boards and a
-PAL/NTSC/SECAM test signal generator at home, so I often can't
-reproduce your problems.  This makes debugging very difficult for me.
-If you have some knowledge and spare time, please try to fix this
-yourself (patches very welcome of course...)  You know: The linux
-slogan is "Do it yourself".
-
-There is a mailing list: linux-media@vger.kernel.org
-http://vger.kernel.org/vger-lists.html#linux-media
-
-If you have trouble with some specific TV card, try to ask there
-instead of mailing me directly.  The chance that someone with the
-same card listens there is much higher...
-
-For problems with sound:  There are a lot of different systems used
-for TV sound all over the world.  And there are also different chips
-which decode the audio signal.  Reports about sound problems ("stereo
-does'nt work") are pretty useless unless you include some details
-about your hardware and the TV sound scheme used in your country (or
-at least the country you are living in).
-
-
-Finally: If you mail some patches for bttv around the world (to
-linux-kernel/Alan/Linus/...), please Cc: me.
-
-
-Have fun with bttv,
-
-  Gerd

-Support for the Leadtek WinView 601 TV/FM by Jon Tombs <jon@gte.esi.us.es>
-
-This card is basically the same as all the rest (Bt484A, Philips tuner),
-the main difference is that they have attached a programmable attenuator to 3
-GPIO lines in order to give some volume control. They have also stuck an
-infra-red remote control decoded on the board, I will add support for this
-when I get time (it simple generates an interrupt for each key press, with

-
-I don't yet have any application to test the radio support. The tuner

-is wrong. If it doesn't work, send me email.
-
-
-- No Thanks to Leadtek they refused to answer any questions about their
-hardware. The driver was written by visual inspection of the card. If you
-use this driver, send an email insult to them, and tell them you won't
-continue buying their hardware unless they support Linux.

-- Little thanks to Princeton Technology Corp (http://www.princeton.com.tw)
-who make the audio attenuator. Their publicly available data-sheet available
-on their web site doesn't include the chip programming information! Hidden

-If the box freezes hard with bttv ...
-=====================================
-
-It might be a bttv driver bug.  It also might be bad hardware.  It also
-might be something else ...
-
-Just mailing me "bttv freezes" isn't going to help much.  This README
-has a few hints how you can help to pin down the problem.
-
-
-bttv bugs
----------
-
-If some version works and another doesn't it is likely to be a driver
-bug.  It is very helpful if you can tell where exactly it broke
-(i.e. the last working and the first broken version).
-
-With a hard freeze you probably doesn't find anything in the logfiles.
-The only way to capture any kernel messages is to hook up a serial
-console and let some terminal application log the messages.  /me uses
-screen.  See Documentation/serial-console.txt for details on setting
-up a serial console.
-
-Read Documentation/oops-tracing.txt to learn how to get any useful
-information out of a register+stack dump printed by the kernel on
-protection faults (so-called "kernel oops").
-
-If you run into some kind of deadlock, you can try to dump a call trace
-for each process using sysrq-t (see Documentation/sysrq.txt).
-This way it is possible to figure where *exactly* some process in "D"
-state is stuck.
-
-I've seen reports that bttv 0.7.x crashes whereas 0.8.x works rock solid
-for some people.  Thus probably a small buglet left somewhere in bttv
-0.7.x.  I have no idea where exactly, it works stable for me and a lot of
-other people.  But in case you have problems with the 0.7.x versions you
-can give 0.8.x a try ...
-
-
-hardware bugs
--------------
-
-Some hardware can't deal with PCI-PCI transfers (i.e. grabber => vga).
-Sometimes problems show up with bttv just because of the high load on
-the PCI bus. The bt848/878 chips have a few workarounds for known
-incompatibilities, see README.quirks.
-
-Some folks report that increasing the pci latency helps too,
-althrought I'm not sure whenever this really fixes the problems or
-only makes it less likely to happen.  Both bttv and btaudio have a
-insmod option to set the PCI latency of the device.
-
-Some mainboard have problems to deal correctly with multiple devices
-doing DMA at the same time.  bttv + ide seems to cause this sometimes,
-if this is the case you likely see freezes only with video and hard disk
-access at the same time.  Updating the IDE driver to get the latest and
-greatest workarounds for hardware bugs might fix these problems.
-
-
-other
------
-
-If you use some binary-only yunk (like nvidia module) try to reproduce
-the problem without.
-
-IRQ sharing is known to cause problems in some cases.  It works just
-fine in theory and many configurations.  Neverless it might be worth a
-try to shuffle around the PCI cards to give bttv another IRQ or make
-it share the IRQ with some other piece of hardware.  IRQ sharing with
-VGA cards seems to cause trouble sometimes.  I've also seen funny
-effects with bttv sharing the IRQ with the ACPI bridge (and
-apci-enabled kernel).

-Normal PCI Mode
----------------
-
-The PCI REQ signal is the logical-or of the incoming function requests.
-The inter-nal GNT[0:1] signals are gated asynchronously with GNT and
-demultiplexed by the audio request signal. Thus the arbiter defaults to
-the video function at power-up and parks there during no requests for
-bus access. This is desirable since the video will request the bus more
-often. However, the audio will have highest bus access priority. Thus
-the audio will have first access to the bus even when issuing a request
-after the video request but before the PCI external arbiter has granted
-access to the Bt879. Neither function can preempt the other once on the
-bus. The duration to empty the entire video PCI FIFO onto the PCI bus is
-very short compared to the bus access latency the audio PCI FIFO can
-tolerate.
-
-
-430FX Compatibility Mode
-------------------------
-
-When using the 430FX PCI, the following rules will ensure
-compatibility:
-
- (1) Deassert REQ at the same time as asserting FRAME.
- (2) Do not reassert REQ to request another bus transaction until after
-     finish-ing the previous transaction.
-
-Since the individual bus masters do not have direct control of REQ, a
-simple logical-or of video and audio requests would violate the rules.
-Thus, both the arbiter and the initiator contain 430FX compatibility
-mode logic. To enable 430FX mode, set the EN_TBFX bit as indicated in
-Device Control Register on page 104.
-
-When EN_TBFX is enabled, the arbiter ensures that the two compatibility
-rules are satisfied. Before GNT is asserted by the PCI arbiter, this
-internal arbiter may still logical-or the two requests. However, once
-the GNT is issued, this arbiter must lock in its decision and now route
-only the granted request to the REQ pin. The arbiter decision lock
-happens regardless of the state of FRAME because it does not know when
-FRAME will be asserted (typically - each initiator will assert FRAME on
-the cycle following GNT). When FRAME is asserted, it is the initiator s
-responsibility to remove its request at the same time. It is the
-arbiters responsibility to allow this request to flow through to REQ and
-not allow the other request to hold REQ asserted. The decision lock may
-be removed at the end of the transaction: for example, when the bus is
-idle (FRAME and IRDY). The arbiter decision may then continue
-asynchronously until GNT is again asserted.
-
-
-Interfacing with Non-PCI 2.1 Compliant Core Logic
--------------------------------------------------
-
-A small percentage of core logic devices may start a bus transaction
-during the same cycle that GNT is de-asserted. This is non PCI 2.1
-compliant. To ensure compatibility when using PCs with these PCI
-controllers, the EN_VSFX bit must be enabled (refer to Device Control
-Register on page 104). When in this mode, the arbiter does not pass GNT
-to the internal functions unless REQ is asserted. This prevents a bus
-transaction from starting the same cycle as GNT is de-asserted. This
-also has the side effect of not being able to take advantage of bus
-parking, thus lowering arbitration performance. The Bt879 drivers must
-query for these non-compliant devices, and set the EN_VSFX bit only if
-required.

-bttv and sound mini howto
-=========================
-
-There are a lot of different bt848/849/878/879 based boards available.
-Making video work often is not a big deal, because this is handled
-completely by the bt8xx chip, which is common on all boards.  But
-sound is handled in slightly different ways on each board.
-
-To handle the grabber boards correctly, there is a array tvcards[] in
-bttv-cards.c, which holds the information required for each board.
-Sound will work only, if the correct entry is used (for video it often
-makes no difference).  The bttv driver prints a line to the kernel
-log, telling which card type is used.  Like this one:
-
-	bttv0: model: BT848(Hauppauge old) [autodetected]
-
-You should verify this is correct.  If it isn't, you have to pass the
-correct board type as insmod argument, "insmod bttv card=2" for
-example.  The file CARDLIST has a list of valid arguments for card.
-If your card isn't listed there, you might check the source code for
-new entries which are not listed yet.  If there isn't one for your
-card, you can check if one of the existing entries does work for you
-(just trial and error...).
-
-Some boards have an extra processor for sound to do stereo decoding
-and other nice features.  The msp34xx chips are used by Hauppauge for
-example.  If your board has one, you might have to load a helper
-module like msp3400.o to make sound work.  If there isn't one for the
-chip used on your board:  Bad luck.  Start writing a new one.  Well,
-you might want to check the video4linux mailing list archive first...
-
-Of course you need a correctly installed soundcard unless you have the
-speakers connected directly to the grabber board.  Hint: check the
-mixer settings too.  ALSA for example has everything muted by default.
-
-
-How sound works in detail
-=========================
-
-Still doesn't work?  Looks like some driver hacking is required.
-Below is a do-it-yourself description for you.
-
-The bt8xx chips have 32 general purpose pins, and registers to control
-these pins.  One register is the output enable register
-(BT848_GPIO_OUT_EN), it says which pins are actively driven by the
-bt848 chip.  Another one is the data register (BT848_GPIO_DATA), where
-you can get/set the status if these pins.  They can be used for input
-and output.
-
-Most grabber board vendors use these pins to control an external chip
-which does the sound routing.  But every board is a little different.
-These pins are also used by some companies to drive remote control
-receiver chips.  Some boards use the i2c bus instead of the gpio pins
-to connect the mux chip.
-
-As mentioned above, there is a array which holds the required
-information for each known board.  You basically have to create a new
-line for your board.  The important fields are these two:
-
-struct tvcard
-{
-	[ ... ]
-	u32 gpiomask;
-	u32 audiomux[6]; /* Tuner, Radio, external, internal, mute, stereo */
-};
-
-gpiomask specifies which pins are used to control the audio mux chip.
-The corresponding bits in the output enable register
-(BT848_GPIO_OUT_EN) will be set as these pins must be driven by the
-bt848 chip.
-
-The audiomux[] array holds the data values for the different inputs
-(i.e. which pins must be high/low for tuner/mute/...).  This will be
-written to the data register (BT848_GPIO_DATA) to switch the audio
-mux.
-
-
-What you have to do is figure out the correct values for gpiomask and
-the audiomux array.  If you have Windows and the drivers four your
-card installed, you might to check out if you can read these registers
-values used by the windows driver.  A tool to do this is available
-from ftp://telepresence.dmem.strath.ac.uk/pub/bt848/winutil, but it
-does'nt work with bt878 boards according to some reports I received.
-Another one with bt878 support is available from
-http://btwincap.sourceforge.net/Files/btspy2.00.zip
-
-You might also dig around in the *.ini files of the Windows applications.
-You can have a look at the board to see which of the gpio pins are
-connected at all and then start trial-and-error ...
-
-
-Starting with release 0.7.41 bttv has a number of insmod options to
-make the gpio debugging easier:
-
-bttv_gpio=0/1		enable/disable gpio debug messages
-gpiomask=n		set the gpiomask value
-audiomux=i,j,...	set the values of the audiomux array
-audioall=a		set the values of the audiomux array (one
-			value for all array elements, useful to check
-			out which effect the particular value has).
-
-The messages printed with bttv_gpio=1 look like this:
-
-	bttv0: gpio: en=00000027, out=00000024 in=00ffffd8 [audio: off]
-
-en  =	output _en_able register (BT848_GPIO_OUT_EN)
-out =	_out_put bits of the data register (BT848_GPIO_DATA),
-	i.e. BT848_GPIO_DATA & BT848_GPIO_OUT_EN
-in  = 	_in_put bits of the data register,
-	i.e. BT848_GPIO_DATA & ~BT848_GPIO_OUT_EN
-
-
-
-Other elements of the tvcards array
-===================================
-
-If you are trying to make a new card work you might find it useful to
-know what the other elements in the tvcards array are good for:
-
-video_inputs    - # of video inputs the card has
-audio_inputs    - historical cruft, not used any more.
-tuner           - which input is the tuner
-svhs            - which input is svhs (all others are labeled composite)
-muxsel          - video mux, input->registervalue mapping
-pll             - same as pll= insmod option
-tuner_type      - same as tuner= insmod option
-*_modulename    - hint whenever some card needs this or that audio
-		  module loaded to work properly.
-has_radio	- whenever this TV card has a radio tuner.
-no_msp34xx	- "1" disables loading of msp3400.o module
-no_tda9875	- "1" disables loading of tda9875.o module
-needs_tvaudio	- set to "1" to load tvaudio.o module
-
-If some config item is specified both from the tvcards array and as
-insmod option, the insmod option takes precedence.
-
-
-
-Good luck,
-
-  Gerd
-
-
-PS: If you have a new working entry, mail it to me.

-"cafe_ccic" is a driver for the Marvell 88ALP01 "cafe" CMOS camera
-controller.  This is the controller found in first-generation OLPC systems,
-and this driver was written with support from the OLPC project.
-
-Current status: the core driver works.  It can generate data in YUV422,
-RGB565, and RGB444 formats.  (Anybody looking at the code will see RGB32 as
-well, but that is a debugging aid which will be removed shortly).  VGA and
-QVGA modes work; CIF is there but the colors remain funky.  Only the OV7670
-sensor is known to work with this controller at this time.
-
-To try it out: either of these commands will work:
-
-     mplayer tv:// -tv driver=v4l2:width=640:height=480 -nosound
-     mplayer tv:// -tv driver=v4l2:width=640:height=480:outfmt=bgr16 -nosound
-
-The "xawtv" utility also works; gqcam does not, for unknown reasons.
-
-There are a few load-time options, most of which can be changed after
-loading via sysfs as well:
-
- - alloc_bufs_at_load:  Normally, the driver will not allocate any DMA
-   buffers until the time comes to transfer data.  If this option is set,
-   then worst-case-sized buffers will be allocated at module load time.
-   This option nails down the memory for the life of the module, but
-   perhaps decreases the chances of an allocation failure later on.
-
- - dma_buf_size: The size of DMA buffers to allocate.  Note that this
-   option is only consulted for load-time allocation; when buffers are
-   allocated at run time, they will be sized appropriately for the current
-   camera settings.
-
- - n_dma_bufs: The controller can cycle through either two or three DMA
-   buffers.  Normally, the driver tries to use three buffers; on faster
-   systems, however, it will work well with only two.
-
- - min_buffers: The minimum number of streaming I/O buffers that the driver
-   will consent to work with.  Default is one, but, on slower systems,
-   better behavior with mplayer can be achieved by setting to a higher
-   value (like six).
-
- - max_buffers: The maximum number of streaming I/O buffers; default is
-   ten.  That number was carefully picked out of a hat and should not be
-   assumed to actually mean much of anything.
-
- - flip: If this boolean parameter is set, the sensor will be instructed to
-   invert the video image.  Whether it makes sense is determined by how
-   your particular camera is mounted.
-
-Work is ongoing with this driver, stay tuned.

-			Programmer's View of Cpia2
-
-Cpia2 is the second generation video coprocessor from VLSI Vision Ltd (now a
-division of ST Microelectronics).  There are two versions.  The first is the
-STV0672, which is capable of up to 30 frames per second (fps) in frame sizes
-up to CIF, and 15 fps for VGA frames.  The STV0676 is an improved version,
-which can handle up to 30 fps VGA.  Both coprocessors can be attached to two
-CMOS sensors - the vvl6410 CIF sensor and the vvl6500 VGA sensor.  These will
-be referred to as the 410 and the 500 sensors, or the CIF and VGA sensors.
-
-The two chipsets operate almost identically.  The core is an 8051 processor,
-running two different versions of firmware.  The 672 runs the VP4 video
-processor code, the 676 runs VP5.  There are a few differences in register
-mappings for the two chips.  In these cases, the symbols defined in the
-header files are marked with VP4 or VP5 as part of the symbol name.
-
-The cameras appear externally as three sets of registers. Setting register
-values is the only way to control the camera.  Some settings are
-interdependant, such as the sequence required to power up the camera. I will
-try to make note of all of these cases.
-
-The register sets are called blocks.  Block 0 is the system block.  This
-section is always powered on when the camera is plugged in.  It contains
-registers that control housekeeping functions such as powering up the video
-processor.  The video processor is the VP block.  These registers control
-how the video from the sensor is processed.  Examples are timing registers,
-user mode (vga, qvga), scaling, cropping, framerates, and so on.  The last
-block is the video compressor (VC).  The video stream sent from the camera is
-compressed as Motion JPEG (JPEGA).  The VC controls all of the compression
-parameters.  Looking at the file cpia2_registers.h, you can get a full view
-of these registers and the possible values for most of them.
-
-One or more registers can be set or read by sending a usb control message to
-the camera.  There are three modes for this.  Block mode requests a number
-of contiguous registers.  Random mode reads or writes random registers with
-a tuple structure containing address/value pairs.  The repeat mode is only
-used by VP4 to load a firmware patch.  It contains a starting address and
-a sequence of bytes to be written into a gpio port.

-	- Compro VideoMate H900
-	- Yuan MPC718
-	- Conexant Raptor PAL/SECAM devkit
-
-2) Some people have problems getting the i2c bus to work.

-The cx23416 can produce (and the cx23415 can also read) raw YUV output. The
-format of a YUV frame is specific to this chip and is called HM12. 'HM' stands
-for 'Hauppauge Macroblock', which is a misnomer as 'Conexant Macroblock' would
-be more accurate.
-
-The format is YUV 4:2:0 which uses 1 Y byte per pixel and 1 U and V byte per
-four pixels.
-
-The data is encoded as two macroblock planes, the first containing the Y
-values, the second containing UV macroblocks.
-
-The Y plane is divided into blocks of 16x16 pixels from left to right
-and from top to bottom. Each block is transmitted in turn, line-by-line.
-
-So the first 16 bytes are the first line of the top-left block, the
-second 16 bytes are the second line of the top-left block, etc. After
-transmitting this block the first line of the block on the right to the
-first block is transmitted, etc.
-
-The UV plane is divided into blocks of 16x8 UV values going from left
-to right, top to bottom. Each block is transmitted in turn, line-by-line.
-
-So the first 16 bytes are the first line of the top-left block and
-contain 8 UV value pairs (16 bytes in total). The second 16 bytes are the
-second line of 8 UV pairs of the top-left block, etc. After transmitting
-this block the first line of the block on the right to the first block is
-transmitted, etc.
-
-The code below is given as an example on how to convert HM12 to separate
-Y, U and V planes. This code assumes frames of 720x576 (PAL) pixels.
-
-The width of a frame is always 720 pixels, regardless of the actual specified
-width.
-
-If the height is not a multiple of 32 lines, then the captured video is
-missing macroblocks at the end and is unusable. So the height must be a
-multiple of 32.

-Format of embedded V4L2_MPEG_STREAM_VBI_FMT_IVTV VBI data
-=========================================================
-
-This document describes the V4L2_MPEG_STREAM_VBI_FMT_IVTV format of the VBI data
-embedded in an MPEG-2 program stream. This format is in part dictated by some
-hardware limitations of the ivtv driver (the driver for the Conexant cx23415/6
-chips), in particular a maximum size for the VBI data. Anything longer is cut
-off when the MPEG stream is played back through the cx23415.
-
-The advantage of this format is it is very compact and that all VBI data for
-all lines can be stored while still fitting within the maximum allowed size.
-
-The stream ID of the VBI data is 0xBD. The maximum size of the embedded data is
-4 + 43 * 36, which is 4 bytes for a header and 2 * 18 VBI lines with a 1 byte
-header and a 42 bytes payload each. Anything beyond this limit is cut off by
-the cx23415/6 firmware. Besides the data for the VBI lines we also need 36 bits
-for a bitmask determining which lines are captured and 4 bytes for a magic cookie,
-signifying that this data package contains V4L2_MPEG_STREAM_VBI_FMT_IVTV VBI data.
-If all lines are used, then there is no longer room for the bitmask. To solve this
-two different magic numbers were introduced:
-
-'itv0': After this magic number two unsigned longs follow. Bits 0-17 of the first
-unsigned long denote which lines of the first field are captured. Bits 18-31 of
-the first unsigned long and bits 0-3 of the second unsigned long are used for the
-second field.
-
-'ITV0': This magic number assumes all VBI lines are captured, i.e. it implicitly
-implies that the bitmasks are 0xffffffff and 0xf.
-
-After these magic cookies (and the 8 byte bitmask in case of cookie 'itv0') the
-captured VBI lines start:
-
-For each line the least significant 4 bits of the first byte contain the data type.
-Possible values are shown in the table below. The payload is in the following 42
-bytes.
-
-Here is the list of possible data types:
-
-#define IVTV_SLICED_TYPE_TELETEXT       0x1     // Teletext (uses lines 6-22 for PAL)
-#define IVTV_SLICED_TYPE_CC             0x4     // Closed Captions (line 21 NTSC)
-#define IVTV_SLICED_TYPE_WSS            0x5     // Wide Screen Signal (line 23 PAL)
-#define IVTV_SLICED_TYPE_VPS            0x7     // Video Programming System (PAL) (line 16)

-This page describes how to make calls to the firmware api.
-
-How to call
-===========
-
-The preferred calling convention is known as the firmware mailbox. The
-mailboxes are basically a fixed length array that serves as the call-stack.
-
-Firmware mailboxes can be located by searching the encoder and decoder memory
-for a 16 byte signature. That signature will be located on a 256-byte boundary.
-
-Signature:
-0x78, 0x56, 0x34, 0x12, 0x12, 0x78, 0x56, 0x34,
-0x34, 0x12, 0x78, 0x56, 0x56, 0x34, 0x12, 0x78
-
-The firmware implements 20 mailboxes of 20 32-bit words. The first 10 are
-reserved for API calls. The second 10 are used by the firmware for event
-notification.
-
-  Index  Name
-  -----  ----
-  0      Flags
-  1      Command
-  2      Return value
-  3      Timeout
-  4-19   Parameter/Result
-
-
-The flags are defined in the following table. The direction is from the
-perspective of the firmware.
-
-  Bit  Direction  Purpose
-  ---  ---------  -------
-  2    O          Firmware has processed the command.
-  1    I          Driver has finished setting the parameters.
-  0    I          Driver is using this mailbox.
-
-
-The command is a 32-bit enumerator. The API specifics may be found in the
-fw-*-api.txt documents.
-
-The return value is a 32-bit enumerator. Only two values are currently defined:
-0=success and -1=command undefined.
-
-There are 16 parameters/results 32-bit fields. The driver populates these fields
-with values for all the parameters required by the call. The driver overwrites
-these fields with result values returned by the call. The API specifics may be
-found in the fw-*-api.txt documents.
-
-The timeout value protects the card from a hung driver thread. If the driver
-doesn't handle the completed call within the timeout specified, the firmware
-will reset that mailbox.
-
-To make an API call, the driver iterates over each mailbox looking for the
-first one available (bit 0 has been cleared). The driver sets that bit, fills
-in the command enumerator, the timeout value and any required parameters. The
-driver then sets the parameter ready bit (bit 1). The firmware scans the
-mailboxes for pending commands, processes them, sets the result code, populates
-the result value array with that call's return values and sets the call
-complete bit (bit 2). Once bit 2 is set, the driver should retrieve the results
-and clear all the flags. If the driver does not perform this task within the
-time set in the timeout register, the firmware will reset that mailbox.
-
-Event notifications are sent from the firmware to the host. The host tells the
-firmware which events it is interested in via an API call. That call tells the
-firmware which notification mailbox to use. The firmware signals the host via
-an interrupt. Only the 16 Results fields are used, the Flags, Command, Return
-value and Timeout words are not used.

-Description
-	Ends playback and clears all decoder buffers. If PTS is not zero,
-	playback stops at specified PTS.
-Param[0]
-	Display 0=last frame, 1=black
-	Note: this takes effect immediately, so if you want to wait for a PTS,
-	then use '0', otherwise the screen goes to black at once.
-	You can call this later (even if there is no playback) with a 1 value
-	to set the screen to black.

-
-Name 	CX2341X_DEC_SET_PLAYBACK_SPEED
-Enum 	3/0x03
-Description
-	Playback stream at speed other than normal. There are two modes of
-	operation:
-	    Smooth: host transfers entire stream and firmware drops unused
-		    frames.
-	    Coarse: host drops frames based on indexing as required to achieve
-		    desired speed.
-Param[0]
-	Bitmap:
-	    0:7  0 normal
-		 1 fast only "1.5 times"
-		 n nX fast, 1/nX slow

-		     '0' during 1.5 times play, every other B frame is dropped
-		     '1' during 1.5 times play, stream is unchanged (bitrate
-			 must not exceed 8mbps)
-	    31   Speed:
-		     '0' slow
-		     '1' fast
-	Note: n is limited to 2. Anything higher does not result in
-	faster playback. Instead the host should start dropping frames.
-Param[1]
-	Direction: 0=forward, 1=reverse
-	Note: to make reverse playback work you have to write full GOPs in
-	reverse order.
-Param[2]
-	Picture mask:

-	    3=I, P frames
-	    7=I, P, B frames
-Param[3]
-	B frames per GOP (for reverse play only)
-	Note: for reverse playback the Picture Mask should be set to I or I, P.

-PVR350 Video decoder registers 0x02002800 -> 0x02002B00
-=======================================================
-
-This list has been worked out through trial and error. There will be mistakes
-and omissions. Some registers have no obvious effect so it's hard to say what
-they do, while others interact with each other, or require a certain load
-sequence. Horizontal filter setup is one example, with six registers working
-in unison and requiring a certain load sequence to correctly configure. The
-indexed colour palette is much easier to set at just two registers, but again
-it requires a certain load sequence.
-
-Some registers are fussy about what they are set to. Load in a bad value & the
-decoder will fail. A firmware reload will often recover, but sometimes a reset
-is required. For registers containing size information, setting them to 0 is
-generally a bad idea. For other control registers i.e. 2878, you'll only find
-out what values are bad when it hangs.

-      bits 0:31
-	Decoder horizontal Y alias register 5
----------------
-2818
-      bits 0:31
-	Decoder horizontal Y alias trigger
-
-     These six registers control the horizontal aliasing filter for the Y plane.
-     The first five registers must all be loaded before accessing the trigger
-     (2818), as this register actually clocks the data through for the first
-     five.
-
-     To correctly program set the filter, this whole procedure must be done 16
-     times. The actual register contents are copied from a lookup-table in the
-     firmware which contains 4 different filter settings.

-      bits 0:31
-	Decoder horizontal UV alias register 5
----------------
-2830
-      bits 0:31
-	Decoder horizontal UV alias trigger
-
-     These six registers control the horizontal aliasing for the UV plane.
-     Operation is the same as the Y filter, with 2830 being the trigger
-     register.
-
---------------------------------------------------------------------------------
-2834
-      bits 0:15
-	Decoder Y source width in pixels
-
-      bits 16:31
-	Decoder Y destination width in pixels
----------------
-2838
-      bits 0:15
-	Decoder UV source width in pixels
-
-      bits 16:31
-	Decoder UV destination width in pixels
-
-     NOTE: For both registers, the resulting image must be fully visible on
-     screen. If the image exceeds the right edge both the source and destination
-     size must be adjusted to reflect the visible portion. For the source width,
-     you must take into account the scaling when calculating the new value.
---------------------------------------------------------------------------------
-

----------------
-2858
-      bits 0:31

-	Decoder ?? unknown
-	  Normally = Reg 2854 >> 1
----------------
-2868
-      bits 0:31
-	Decoder ?? unknown
-	  Usually 0
-
-     Most of these registers either control horizontal scaling, or appear linked
-     to it in some way. Register 2854 contains the 'master' value & the other
-     registers can be calculated from that one. You must also remember to
-     correctly set the divider in Reg 2874.
-
-     To enlarge:
-	     Reg 2854 = (source_width * 0x00200000) / destination_width
-	     Reg 2874 = No divide
-
-     To reduce from full size down to half size:
-	     Reg 2854 = (source_width/2 * 0x00200000) / destination width
-	     Reg 2874 = Divide by 2
-
-     To reduce from half size down to quarter size:
-	     Reg 2854 = (source_width/4 * 0x00200000) / destination width
-	     Reg 2874 = Divide by 4
-
-     The result is always rounded up.

-288C
-      bits 0:15

-	osd ?? unknown
-	  Same as bits 0:15
-
---------------------------------------------------------------------------------
-2890
-      bits 0:11
-	Decoder output horizontal offset.
-
-     Horizontal offset moves the video image right. A small left shift is
-     possible, but it's better to use reg 2870 for that due to its greater
-     range.
-
-     NOTE: Video corruption will occur if video window is shifted off the right
-     edge. To avoid this read the notes for 2834 & 2838.
---------------------------------------------------------------------------------
-2894
-      bits 0:23
-	Decoder output video surround colour.
-
-     Contains the colour (in yuv) used to fill the screen when the video is
-     running in a window.
---------------------------------------------------------------------------------
-2898
-      bits 0:23
-	Decoder video window colour
-	  Contains the colour (in yuv) used to fill the video window when the

-
-      bit 24
-	Decoder video output
-	  0 = Video on
-	  1 = Video off
-

-	  1 = UV,Y
-
-      bit 29
-	Decoder second plane byte order
-	  0 = Normal (UV)
-	  1 = Swapped (VU)
-
-     In normal usage, the first plane is Y & the second plane is UV. Though the
-     order of the planes can be swapped, only the byte order of the second plane
-     can be swapped. This isn't much use for the Y plane, but can be useful for
-     the UV plane.

-	Decoder vertical Y alias trigger
-
-     These three registers control the vertical aliasing filter for the Y plane.
-     Operation is similar to the horizontal Y filter (2804). The only real
-     difference is that there are only two registers to set before accessing
-     the trigger register (2908). As for the horizontal filter, the values are
-     taken from a lookup table in the firmware, and the procedure must be
-     repeated 16 times to fully program the filter.

-	     Reg 296C = Divide by 2

-
-     When the bits-per-pixel is set to 8, the colour mode is ignored and
-     assumed to be 8 bit indexed. For 16 & 32 bits-per-pixel the colour depth
-     is honoured, and when using a colour depth that requires fewer bytes than
-     allocated the extra bytes are used as padding. So for a 32 bpp with 8 bit
-     index colour, there are 3 padding bytes per pixel. It's also possible to
-     select 16bpp with a 32 bit colour mode. This results in the pixel width
-     being doubled, but the color key will not work as expected in this mode.
-
-     Colour key is as it suggests. You designate a colour which will become
-     completely transparent. When using 565, 555 or 444 colour modes, the
-     colour key is always 16 bits wide. The colour to key on is set in Reg 2A18.
-
-     Local alpha works differently depending on the colour mode. For 32bpp & 8
-     bit indexed, local alpha is a per-pixel 256 step transparency, with 0 being
-     transparent and 255 being solid. For the 16bpp modes 555 & 444, the unused
-     bit(s) act as a simple transparency switch, with 0 being solid & 1 being
-     fully transparent. There is no local alpha support for 16bit 565.
-
-     Global alpha is a 256 step transparency that applies to the entire osd,
-     with 0 being transparent & 255 being solid.
-
-     It's possible to combine colour key, local alpha & global alpha.

-This page describes the structures and procedures used by the cx2341x DMA
-engine.
-
-Introduction
-============
-
-The cx2341x PCI interface is busmaster capable. This means it has a DMA
-engine to efficiently transfer large volumes of data between the card and main
-memory without requiring help from a CPU. Like most hardware, it must operate
-on contiguous physical memory. This is difficult to come by in large quantities
-on virtual memory machines.
-
-Therefore, it also supports a technique called "scatter-gather". The card can
-transfer multiple buffers in one operation. Instead of allocating one large
-contiguous buffer, the driver can allocate several smaller buffers.
-
-In practice, I've seen the average transfer to be roughly 80K, but transfers
-above 128K were not uncommon, particularly at startup. The 128K figure is
-important, because that is the largest block that the kernel can normally
-allocate. Even still, 128K blocks are hard to come by, so the driver writer is
-urged to choose a smaller block size and learn the scatter-gather technique.
-
-Mailbox #10 is reserved for DMA transfer information.
-
-Note: the hardware expects little-endian data ('intel format').
-
-Flow
-====
-
-This section describes, in general, the order of events when handling DMA
-transfers. Detailed information follows this section.
-
-- The card raises the Encoder interrupt.
-- The driver reads the transfer type, offset and size from Mailbox #10.
-- The driver constructs the scatter-gather array from enough free dma buffers
-  to cover the size.
-- The driver schedules the DMA transfer via the ScheduleDMAtoHost API call.
-- The card raises the DMA Complete interrupt.
-- The driver checks the DMA status register for any errors.
-- The driver post-processes the newly transferred buffers.
-
-NOTE! It is possible that the Encoder and DMA Complete interrupts get raised
-simultaneously. (End of the last, start of the next, etc.)
-
-Mailbox #10
-===========
-
-The Flags, Command, Return Value and Timeout fields are ignored.
-
-Name:       Mailbox #10
-Results[0]: Type: 0: MPEG.
-Results[1]: Offset: The position relative to the card's memory space.
-Results[2]: Size: The exact number of bytes to transfer.
-
-My speculation is that since the StartCapture API has a capture type of "RAW"
-available, that the type field will have other values that correspond to YUV
-and PCM data.
-
-Scatter-Gather Array
-====================
-
-The scatter-gather array is a contiguously allocated block of memory that
-tells the card the source and destination of each data-block to transfer.
-Card "addresses" are derived from the offset supplied by Mailbox #10. Host
-addresses are the physical memory location of the target DMA buffer.
-
-Each S-G array element is a struct of three 32-bit words. The first word is
-the source address, the second is the destination address. Both take up the
-entire 32 bits. The lowest 18 bits of the third word is the transfer byte
-count. The high-bit of the third word is the "last" flag. The last-flag tells
-the card to raise the DMA_DONE interrupt. From hard personal experience, if
-you forget to set this bit, the card will still "work" but the stream will
-most likely get corrupted.
-
-The transfer count must be a multiple of 256. Therefore, the driver will need
-to track how much data in the target buffer is valid and deal with it
-accordingly.
-
-Array Element:
-
-- 32-bit Source Address
-- 32-bit Destination Address
-- 14-bit reserved (high bit is the last flag)
-- 18-bit byte count
-
-DMA Transfer Status
-===================
-
-Register 0x0004 holds the DMA Transfer Status:
-
-Bit
-0   read completed
-1   write completed
-2   DMA read error
-3   DMA write error
-4   Scatter-Gather array error

-This document describes the cx2341x memory map and documents some of the register
-space.
-
-Note: the memory long words are little-endian ('intel format').
-
-Warning! This information was figured out from searching through the memory and
-registers, this information may not be correct and is certainly not complete, and
-was not derived from anything more than searching through the memory space with
-commands like:
-
-	ivtvctl -O min=0x02000000,max=0x020000ff
-
-So take this as is, I'm always searching for more stuff, it's a large
-register space :-).
-
-Memory Map
-==========
-
-The cx2341x exposes its entire 64M memory space to the PCI host via the PCI BAR0
-(Base Address Register 0). The addresses here are offsets relative to the
-address held in BAR0.
-
-0x00000000-0x00ffffff Encoder memory space

-
-Registers
-=========
-
-The registers occupy the 64k space starting at the 0x02000000 offset from BAR0.
-All of these registers are 32 bits wide.
-
-DMA Registers 0x000-0xff:
-

- 0x08 - pci DMA pointer for read link list
- 0x0c - pci DMA pointer for write link list
- 0x10 - read/write DMA enable:
-	1=read enable, 2=write enable
- 0x14 - always 0xffffffff, if set any lower instability occurs, 0x00 crashes
- 0x18 - ??
- 0x1c - always 0x20 or 32, smaller values slow down DMA transactions
- 0x20 - always value of 0x780a010a
- 0x24-0x3c - usually just random values???
- 0x40 - Interrupt status
- 0x44 - Write a bit here and shows up in Interrupt status 0x40
- 0x48 - Interrupt Mask
- 0x4C - always value of 0xfffdffff,
-	if changed to 0xffffffff DMA write interrupts break.
- 0x50 - always 0xffffffff
- 0x54 - always 0xffffffff (0x4c, 0x50, 0x54 seem like interrupt masks, are
-	3 processors on chip, Java ones, VPU, SPU, APU, maybe these are the
-	interrupt masks???).
- 0x60-0x7C - random values
- 0x80 - first write linked list reg, for Encoder Memory addr
- 0x84 - first write linked list reg, for pci memory addr
- 0x88 - first write linked list reg, for length of buffer in memory addr
-	(|0x80000000 or this for last link)
- 0x8c-0xdc - rest of write linked list reg, 8 sets of 3 total, DMA goes here
-	from linked list addr in reg 0x0c, firmware must push through or
-	something.
- 0xe0 - first (and only) read linked list reg, for pci memory addr
- 0xe4 - first (and only) read linked list reg, for Decoder memory addr
- 0xe8 - first (and only) read linked list reg, for length of buffer
- 0xec-0xff - Nothing seems to be in these registers, 0xec-f4 are 0x00000000.

-  bit [18]  IR_SMP_INT Set when 32 input samples have been collected over
-  gpio[16] pin into GP_SAMPLE register.
-
-What's missing from the data sheet:
-
-Setup 4KHz sampling rate (roughly 2x oversampled; good enough for our RC5
-compat remote)
-set register 0x35C050 to  0xa80a80
-
-enable sampling
-set register 0x35C054 to 0x5
-
-Of course, enable the IRQ bit 18 in the interrupt mask register .(and
-provide for a handler)
-
-GP_SAMPLE register is at 0x35C058
-
-Bits are then right shifted into the GP_SAMPLE register at the specified
-rate; you get an interrupt when a full DWORD is received.
-You need to recover the actual RC5 bits out of the (oversampled) IR sensor
-bits. (Hint: look for the 0/1and 1/0 crossings of the RC5 bi-phase data)  An
-actual raw RC5 code will span 2-3 DWORDS, depending on the actual alignment.
-
-I'm pretty sure when no IR signal is present the receiver is always in a
-marking state(1); but stray light, etc can cause intermittent noise values
-as well.  Remember, this is a free running sample of the IR receiver state
-over time, so don't assume any sample starts at any particular place.

-Samsung S5P/EXYNOS4 FIMC driver
-
-Copyright (C) 2012 - 2013 Samsung Electronics Co., Ltd.
----------------------------------------------------------------------------
-
-The FIMC (Fully Interactive Mobile Camera) device available in Samsung
-SoC Application Processors is an integrated camera host interface, color
-space converter, image resizer and rotator.  It's also capable of capturing
-data from LCD controller (FIMD) through the SoC internal writeback data
-path.  There are multiple FIMC instances in the SoCs (up to 4), having
-slightly different capabilities, like pixel alignment constraints, rotator
-availability, LCD writeback support, etc. The driver is located at
-drivers/media/platform/exynos4-is directory.
-
-1. Supported SoCs
-=================
-
-S5PC100 (mem-to-mem only), S5PV210, EXYNOS4210
-
-2. Supported features
-=====================
-
- - camera parallel interface capture (ITU-R.BT601/565);
- - camera serial interface capture (MIPI-CSI2);
- - memory-to-memory processing (color space conversion, scaling, mirror
-   and rotation);
- - dynamic pipeline re-configuration at runtime (re-attachment of any FIMC
-   instance to any parallel video input or any MIPI-CSI front-end);
- - runtime PM and system wide suspend/resume
-
-Not currently supported:
- - LCD writeback input
- - per frame clock gating (mem-to-mem)
-
-3. Files partitioning

-
-4. User space interfaces
-========================
-
-4.1. Media device interface
-
-The driver supports Media Controller API as defined at
-https://linuxtv.org/downloads/v4l-dvb-apis/media_common.html
-The media device driver name is "SAMSUNG S5P FIMC".
-
-The purpose of this interface is to allow changing assignment of FIMC instances
-to the SoC peripheral camera input at runtime and optionally to control internal
-connections of the MIPI-CSIS device(s) to the FIMC entities.
-
-The media device interface allows to configure the SoC for capturing image
-data from the sensor through more than one FIMC instance (e.g. for simultaneous
-viewfinder and still capture setup).
-Reconfiguration is done by enabling/disabling media links created by the driver
-during initialization. The internal device topology can be easily discovered
-through media entity and links enumeration.
-
-4.2. Memory-to-memory video node
-
-V4L2 memory-to-memory interface at /dev/video? device node.  This is standalone
-video device, it has no media pads. However please note the mem-to-mem and
-capture video node operation on same FIMC instance is not allowed.  The driver
-detects such cases but the applications should prevent them to avoid an
-undefined behaviour.
-
-4.3. Capture video node
-
-The driver supports V4L2 Video Capture Interface as defined at:
-https://linuxtv.org/downloads/v4l-dvb-apis/devices.html
-
-At the capture and mem-to-mem video nodes only the multi-planar API is
-supported. For more details see:
-https://linuxtv.org/downloads/v4l-dvb-apis/planar-apis.html
-
-4.4. Camera capture subdevs
-
-Each FIMC instance exports a sub-device node (/dev/v4l-subdev?), a sub-device
-node is also created per each available and enabled at the platform level
-MIPI-CSI receiver device (currently up to two).
-
-4.5. sysfs
-
-In order to enable more precise camera pipeline control through the sub-device
-API the driver creates a sysfs entry associated with "s5p-fimc-md" platform
-device. The entry path is: /sys/platform/devices/s5p-fimc-md/subdev_conf_mode.
-
-In typical use case there could be a following capture pipeline configuration:
-sensor subdev -> mipi-csi subdev -> fimc subdev -> video node
-
-When we configure these devices through sub-device API at user space, the
-configuration flow must be from left to right, and the video node is
-configured as last one.
-When we don't use sub-device user space API the whole configuration of all
-devices belonging to the pipeline is done at the video node driver.
-The sysfs entry allows to instruct the capture node driver not to configure
-the sub-devices (format, crop), to avoid resetting the subdevs' configuration
-when the last configuration steps at the video node is performed.
-
-For full sub-device control support (subdevs configured at user space before
-starting streaming):
-# echo "sub-dev" > /sys/platform/devices/s5p-fimc-md/subdev_conf_mode
-
-For V4L2 video node control only (subdevs configured internally by the host
-driver):
-# echo "vid-dev" > /sys/platform/devices/s5p-fimc-md/subdev_conf_mode
-This is a default option.
-
-5. Device mapping to video and subdev device nodes
-==================================================
-
-There are associated two video device nodes with each device instance in
-hardware - video capture and mem-to-mem and additionally a subdev node for
-more precise FIMC capture subsystem control. In addition a separate v4l2
-sub-device node is created per each MIPI-CSIS device.
-
-How to find out which /dev/video? or /dev/v4l-subdev? is assigned to which
-device?
-
-You can either grep through the kernel log to find relevant information, i.e.
-# dmesg | grep -i fimc
-(note that udev, if present, might still have rearranged the video nodes),
-
-or retrieve the information from /dev/media? with help of the media-ctl tool:
-# media-ctl -p
-
-7. Build
-========
-
-If the driver is built as a loadable kernel module (CONFIG_VIDEO_SAMSUNG_S5P_FIMC=m)
-two modules are created (in addition to the core v4l2 modules): s5p-fimc.ko and
-optional s5p-csis.ko (MIPI-CSI receiver subdev).

-
-Setup 4KHz sampling rate (roughly 2x oversampled; good enough for our RC5
-compat remote)
-set register 0x35C050 to  0xa80a80
-
-enable sampling
-set register 0x35C054 to 0x5
-
-Of course, enable the IRQ bit 18 in the interrupt mask register .(and
-provide for a handler)
-
-GP_SAMPLE register is at 0x35C058
-
-Bits are then right shifted into the GP_SAMPLE register at the specified
-rate; you get an interrupt when a full DWORD is received.
-You need to recover the actual RC5 bits out of the (oversampled) IR sensor
-bits. (Hint: look for the 0/1and 1/0 crossings of the RC5 bi-phase data)  An
-actual raw RC5 code will span 2-3 DWORDS, depending on the actual alignment.
-
-I'm pretty sure when no IR signal is present the receiver is always in a

-Vaio Picturebook Motion Eye Camera Driver Readme
-------------------------------------------------
-	Copyright (C) 2001-2004 Stelian Pop <stelian@popies.net>
-	Copyright (C) 2001-2002 Alcôve <www.alcove.com>
-	Copyright (C) 2000 Andrew Tridgell <tridge@samba.org>
-
-This driver enable the use of video4linux compatible applications with the
-Motion Eye camera. This driver requires the "Sony Laptop Extras" driver (which
-can be found in the "Misc devices" section of the kernel configuration utility)
-to be compiled and installed (using its "camera=1" parameter).
-
-It can do at maximum 30 fps @ 320x240 or 15 fps @ 640x480.
-
-Grabbing is supported in packed YUV colorspace only.
-
-MJPEG hardware grabbing is supported via a private API (see below).
-
-Hardware supported:
--------------------
-
-This driver supports the 'second' version of the MotionEye camera :)
-
-The first version was connected directly on the video bus of the Neomagic
-video card and is unsupported.
-
-The second one, made by Kawasaki Steel is fully supported by this
-driver (PCI vendor/device is 0x136b/0xff01)
-
-The third one, present in recent (more or less last year) Picturebooks
-(C1M* models), is not supported. The manufacturer has given the specs
-to the developers under a NDA (which allows the development of a GPL
-driver however), but things are not moving very fast (see
-http://r-engine.sourceforge.net/) (PCI vendor/device is 0x10cf/0x2011).
-
-There is a forth model connected on the USB bus in TR1* Vaio laptops.
-This camera is not supported at all by the current driver, in fact
-little information if any is available for this camera
-(USB vendor/device is 0x054c/0x0107).
-
-Driver options:
----------------
-
-Several options can be passed to the meye driver using the standard
-module argument syntax (<param>=<value> when passing the option to the
-module or meye.<param>=<value> on the kernel boot line when meye is
-statically linked into the kernel). Those options are:
-
-	gbuffers:	number of capture buffers, default is 2 (32 max)
-
-	gbufsize:	size of each capture buffer, default is 614400
-
-	video_nr:	video device to register (0 = /dev/video0, etc)
-
-Module use:
------------
-
-In order to automatically load the meye module on use, you can put those lines
-in your /etc/modprobe.d/meye.conf file:
-
-	alias char-major-81 videodev
-	alias char-major-81-0 meye
-	options meye gbuffers=32
-
-Usage:
-------
-
-	xawtv >= 3.49 (<http://bytesex.org/xawtv/>)
-		for display and uncompressed video capture:
-
-			xawtv -c /dev/video0 -geometry 640x480
-				or
-			xawtv -c /dev/video0 -geometry 320x240
-
-	motioneye (<http://popies.net/meye/>)
-		for getting ppm or jpg snapshots, mjpeg video
-
-Private API:
-------------
-
-	The driver supports frame grabbing with the video4linux API,
-	so all video4linux tools (like xawtv) should work with this driver.
-
-	Besides the video4linux interface, the driver has a private interface
-	for accessing the Motion Eye extended parameters (camera sharpness,
-	agc, video framerate), the shapshot and the MJPEG capture facilities.
-
-	This interface consists of several ioctls (prototypes and structures
-	can be found in include/linux/meye.h):
-
-	MEYEIOC_G_PARAMS
-	MEYEIOC_S_PARAMS
-		Get and set the extended parameters of the motion eye camera.
-		The user should always query the current parameters with
-		MEYEIOC_G_PARAMS, change what he likes and then issue the
-		MEYEIOC_S_PARAMS call (checking for -EINVAL). The extended
-		parameters are described by the meye_params structure.
-
-
-	MEYEIOC_QBUF_CAPT
-		Queue a buffer for capture (the buffers must have been
-		obtained with a VIDIOCGMBUF call and mmap'ed by the
-		application). The argument to MEYEIOC_QBUF_CAPT is the
-		buffer number to queue (or -1 to end capture). The first
-		call to MEYEIOC_QBUF_CAPT starts the streaming capture.
-
-	MEYEIOC_SYNC
-		Takes as an argument the buffer number you want to sync.
-		This ioctl blocks until the buffer is filled and ready
-		for the application to use. It returns the buffer size.
-
-	MEYEIOC_STILLCAPT
-	MEYEIOC_STILLJCAPT
-		Takes a snapshot in an uncompressed or compressed jpeg format.
-		This ioctl blocks until the snapshot is done and returns (for
-		jpeg snapshot) the size of the image. The image data is
-		available from the first mmap'ed buffer.
-
-	Look at the 'motioneye' application code for an actual example.
-
-Bugs / Todo:
-------------
-
-	- 'motioneye' still uses the meye private v4l1 API extensions.

-Introduction
-============
-
-This file documents the Texas Instruments OMAP 3 Image Signal Processor (ISP)
-driver located under drivers/media/platform/omap3isp. The original driver was
-written by Texas Instruments but since that it has been rewritten (twice) at
-Nokia.
-
-The driver has been successfully used on the following versions of OMAP 3:
-
-	3430
-	3530
-	3630
-
-The driver implements V4L2, Media controller and v4l2_subdev interfaces.
-Sensor, lens and flash drivers using the v4l2_subdev interface in the kernel
-are supported.
-
-
-Split to subdevs
-================
-
-The OMAP 3 ISP is split into V4L2 subdevs, each of the blocks inside the ISP
-having one subdev to represent it. Each of the subdevs provide a V4L2 subdev
-interface to userspace.
-
-	OMAP3 ISP CCP2
-	OMAP3 ISP CSI2a
-	OMAP3 ISP CCDC
-	OMAP3 ISP preview
-	OMAP3 ISP resizer
-	OMAP3 ISP AEWB
-	OMAP3 ISP AF
-	OMAP3 ISP histogram
-
-Each possible link in the ISP is modelled by a link in the Media controller
-interface. For an example program see [2].
-
-
-Controlling the OMAP 3 ISP
-==========================
-
-In general, the settings given to the OMAP 3 ISP take effect at the beginning
-of the following frame. This is done when the module becomes idle during the
-vertical blanking period on the sensor. In memory-to-memory operation the pipe
-is run one frame at a time. Applying the settings is done between the frames.
-
-All the blocks in the ISP, excluding the CSI-2 and possibly the CCP2 receiver,
-insist on receiving complete frames. Sensors must thus never send the ISP
-partial frames.
-
-Autoidle does have issues with some ISP blocks on the 3430, at least.
-Autoidle is only enabled on 3630 when the omap3isp module parameter autoidle
-is non-zero.
-
-
-Events
-======
-
-The OMAP 3 ISP driver does support the V4L2 event interface on CCDC and
-statistics (AEWB, AF and histogram) subdevs.
-
-The CCDC subdev produces V4L2_EVENT_FRAME_SYNC type event on HS_VS
-interrupt which is used to signal frame start. Earlier version of this
-driver used V4L2_EVENT_OMAP3ISP_HS_VS for this purpose. The event is
-triggered exactly when the reception of the first line of the frame starts
-in the CCDC module. The event can be subscribed on the CCDC subdev.
-
-(When using parallel interface one must pay account to correct configuration
-of the VS signal polarity. This is automatically correct when using the serial
-receivers.)
-
-Each of the statistics subdevs is able to produce events. An event is
-generated whenever a statistics buffer can be dequeued by a user space
-application using the VIDIOC_OMAP3ISP_STAT_REQ IOCTL. The events available
-are:
-
-	V4L2_EVENT_OMAP3ISP_AEWB
-	V4L2_EVENT_OMAP3ISP_AF
-	V4L2_EVENT_OMAP3ISP_HIST
-
-The type of the event data is struct omap3isp_stat_event_status for these
-ioctls. If there is an error calculating the statistics, there will be an
-event as usual, but no related statistics buffer. In this case
-omap3isp_stat_event_status.buf_err is set to non-zero.
-
-
-Private IOCTLs
-==============
-
-The OMAP 3 ISP driver supports standard V4L2 IOCTLs and controls where
-possible and practical. Much of the functions provided by the ISP, however,
-does not fall under the standard IOCTLs --- gamma tables and configuration of
-statistics collection are examples of such.
-
-In general, there is a private ioctl for configuring each of the blocks
-containing hardware-dependent functions.
-
-The following private IOCTLs are supported:
-
-	VIDIOC_OMAP3ISP_CCDC_CFG
-	VIDIOC_OMAP3ISP_PRV_CFG
-	VIDIOC_OMAP3ISP_AEWB_CFG
-	VIDIOC_OMAP3ISP_HIST_CFG
-	VIDIOC_OMAP3ISP_AF_CFG
-	VIDIOC_OMAP3ISP_STAT_REQ
-	VIDIOC_OMAP3ISP_STAT_EN
-
-The parameter structures used by these ioctls are described in
-include/linux/omap3isp.h. The detailed functions of the ISP itself related to
-a given ISP block is described in the Technical Reference Manuals (TRMs) ---
-see the end of the document for those.
-
-While it is possible to use the ISP driver without any use of these private
-IOCTLs it is not possible to obtain optimal image quality this way. The AEWB,
-AF and histogram modules cannot be used without configuring them using the
-appropriate private IOCTLs.
-
-
-CCDC and preview block IOCTLs
-=============================
-
-The VIDIOC_OMAP3ISP_CCDC_CFG and VIDIOC_OMAP3ISP_PRV_CFG IOCTLs are used to
-configure, enable and disable functions in the CCDC and preview blocks,
-respectively. Both IOCTLs control several functions in the blocks they
-control. VIDIOC_OMAP3ISP_CCDC_CFG IOCTL accepts a pointer to struct
-omap3isp_ccdc_update_config as its argument. Similarly VIDIOC_OMAP3ISP_PRV_CFG
-accepts a pointer to struct omap3isp_prev_update_config. The definition of
-both structures is available in [1].
-
-The update field in the structures tells whether to update the configuration
-for the specific function and the flag tells whether to enable or disable the
-function.
-
-The update and flag bit masks accept the following values. Each separate
-functions in the CCDC and preview blocks is associated with a flag (either
-disable or enable; part of the flag field in the structure) and a pointer to
-configuration data for the function.
-
-Valid values for the update and flag fields are listed here for
-VIDIOC_OMAP3ISP_CCDC_CFG. Values may be or'ed to configure more than one
-function in the same IOCTL call.
-
-        OMAP3ISP_CCDC_ALAW
-        OMAP3ISP_CCDC_LPF
-        OMAP3ISP_CCDC_BLCLAMP
-        OMAP3ISP_CCDC_BCOMP
-        OMAP3ISP_CCDC_FPC
-        OMAP3ISP_CCDC_CULL
-        OMAP3ISP_CCDC_CONFIG_LSC
-        OMAP3ISP_CCDC_TBL_LSC
-
-The corresponding values for the VIDIOC_OMAP3ISP_PRV_CFG are here:
-
-        OMAP3ISP_PREV_LUMAENH
-        OMAP3ISP_PREV_INVALAW
-        OMAP3ISP_PREV_HRZ_MED
-        OMAP3ISP_PREV_CFA
-        OMAP3ISP_PREV_CHROMA_SUPP
-        OMAP3ISP_PREV_WB
-        OMAP3ISP_PREV_BLKADJ
-        OMAP3ISP_PREV_RGB2RGB
-        OMAP3ISP_PREV_COLOR_CONV
-        OMAP3ISP_PREV_YC_LIMIT
-        OMAP3ISP_PREV_DEFECT_COR
-        OMAP3ISP_PREV_GAMMABYPASS
-        OMAP3ISP_PREV_DRK_FRM_CAPTURE
-        OMAP3ISP_PREV_DRK_FRM_SUBTRACT
-        OMAP3ISP_PREV_LENS_SHADING
-        OMAP3ISP_PREV_NF
-        OMAP3ISP_PREV_GAMMA
-
-The associated configuration pointer for the function may not be NULL when
-enabling the function. When disabling a function the configuration pointer is
-ignored.
-
-
-Statistic blocks IOCTLs
-=======================
-
-The statistics subdevs do offer more dynamic configuration options than the
-other subdevs. They can be enabled, disable and reconfigured when the pipeline
-is in streaming state.
-
-The statistics blocks always get the input image data from the CCDC (as the
-histogram memory read isn't implemented). The statistics are dequeueable by
-the user from the statistics subdev nodes using private IOCTLs.
-
-The private IOCTLs offered by the AEWB, AF and histogram subdevs are heavily
-reflected by the register level interface offered by the ISP hardware. There
-are aspects that are purely related to the driver implementation and these are
-discussed next.
-
-VIDIOC_OMAP3ISP_STAT_EN
------------------------
-
-This private IOCTL enables/disables a statistic module. If this request is
-done before streaming, it will take effect as soon as the pipeline starts to
-stream.  If the pipeline is already streaming, it will take effect as soon as
-the CCDC becomes idle.
-
-VIDIOC_OMAP3ISP_AEWB_CFG, VIDIOC_OMAP3ISP_HIST_CFG and VIDIOC_OMAP3ISP_AF_CFG
------------------------------------------------------------------------------
-
-Those IOCTLs are used to configure the modules. They require user applications
-to have an in-depth knowledge of the hardware. Most of the fields explanation
-can be found on OMAP's TRMs. The two following fields common to all the above
-configure private IOCTLs require explanation for better understanding as they

-
-omap3isp_[h3a_af/h3a_aewb/hist]_config.buf_size:
-
-The modules handle their buffers internally. The necessary buffer size for the
-module's data output depends on the requested configuration. Although the
-driver supports reconfiguration while streaming, it does not support a
-reconfiguration which requires bigger buffer size than what is already
-internally allocated if the module is enabled. It will return -EBUSY on this
-case. In order to avoid such condition, either disable/reconfigure/enable the
-module or request the necessary buffer size during the first configuration
-while the module is disabled.
-
-The internal buffer size allocation considers the requested configuration's
-minimum buffer size and the value set on buf_size field. If buf_size field is
-out of [minimum, maximum] buffer size range, it's clamped to fit in there.
-The driver then selects the biggest value. The corrected buf_size value is
-written back to user application.
-
-omap3isp_[h3a_af/h3a_aewb/hist]_config.config_counter:
-
-As the configuration doesn't take effect synchronously to the request, the
-driver must provide a way to track this information to provide more accurate
-data. After a configuration is requested, the config_counter returned to user
-space application will be an unique value associated to that request. When
-user application receives an event for buffer availability or when a new
-buffer is requested, this config_counter is used to match a buffer data and a
-configuration.
-
-VIDIOC_OMAP3ISP_STAT_REQ
-------------------------
-
-Send to user space the oldest data available in the internal buffer queue and
-discards such buffer afterwards. The field omap3isp_stat_data.frame_number
-matches with the video buffer's field_count.

-Introduction
-------------
-
-The OMAP44XX family of chips contains the Imaging SubSystem (a.k.a. ISS),
-Which contains several components that can be categorized in 3 big groups:
-
-- Interfaces (2 Interfaces: CSI2-A & CSI2-B/CCP2)
-- ISP (Image Signal Processor)
-- SIMCOP (Still Image Coprocessor)
-
-For more information, please look in [1] for latest version of:
-	"OMAP4430 Multimedia Device Silicon Revision 2.x"
-
-As of Revision AB, the ISS is described in detail in section 8.
-
-This driver is supporting _only_ the CSI2-A/B interfaces for now.
-
-It makes use of the Media Controller framework [2], and inherited most of the
-code from OMAP3 ISP driver (found under drivers/media/platform/omap3isp/*),
-except that it doesn't need an IOMMU now for ISS buffers memory mapping.
-
-Supports usage of MMAP buffers only (for now).
-
-Tested platforms
-----------------
-
-- OMAP4430SDP, w/ ES2.1 GP & SEVM4430-CAM-V1-0 (Contains IMX060 & OV5640, in
-  which only the last one is supported, outputting YUV422 frames).
-
-- TI Blaze MDP, w/ OMAP4430 ES2.2 EMU (Contains 1 IMX060 & 2 OV5650 sensors, in
-  which only the OV5650 are supported, outputting RAW10 frames).
-
-- PandaBoard, Rev. A2, w/ OMAP4430 ES2.1 GP & OV adapter board, tested with
-  following sensors:
-  * OV5640
-  * OV5650
-
-- Tested on mainline kernel:

-                              ======================
-
-Constraints
------------
-  a) Image size for YUV422P format
-     All YUV422P images are enforced to have width x height % 16 = 0.
-     This is due to DMA constraints, which transfers only planes of 8 byte
-     multiples.
-
-
-Global video workflow
----------------------
-  a) QCI stopped
-     Initialy, the QCI interface is stopped.
-     When a buffer is queued (pxa_videobuf_ops->buf_queue), the QCI starts.
-
-  b) QCI started
-     More buffers can be queued while the QCI is started without halting the
-     capture.  The new buffers are "appended" at the tail of the DMA chain, and
-     smoothly captured one frame after the other.
-
-     Once a buffer is filled in the QCI interface, it is marked as "DONE" and
-     removed from the active buffers list. It can be then requeud or dequeued by
-     userland application.
-
-     Once the last buffer is filled in, the QCI interface stops.
-
-  c) Capture global finite state machine schema

-            - "DMA: run" means at least 1 DMA channel is still running
-
-DMA usage
----------
-  a) DMA flow
-     - first buffer queued for capture
-       Once a first buffer is queued for capture, the QCI is started, but data
-       transfer is not started. On "End Of Frame" interrupt, the irq handler
-       starts the DMA chain.
-     - capture of one videobuffer
-       The DMA chain starts transferring data into videobuffer RAM pages.
-       When all pages are transferred, the DMA irq is raised on "ENDINTR" status
-     - finishing one videobuffer
-       The DMA irq handler marks the videobuffer as "done", and removes it from
-       the active running queue
-       Meanwhile, the next videobuffer (if there is one), is transferred by DMA
-     - finishing the last videobuffer
-       On the DMA irq of the last videobuffer, the QCI is stopped.
-
-  b) DMA prepared buffer will have this structure
-
-     +------------+-----+---------------+-----------------+
-     | desc-sg[0] | ... | desc-sg[last] | finisher/linker |
-     +------------+-----+---------------+-----------------+
-
-     This structure is pointed by dma->sg_cpu.
-     The descriptors are used as follows :
-      - desc-sg[i]: i-th descriptor, transferring the i-th sg
-        element to the video buffer scatter gather
-      - finisher: has ddadr=DADDR_STOP, dcmd=ENDIRQEN
-      - linker: has ddadr= desc-sg[0] of next video buffer, dcmd=0
-
-     For the next schema, let's assume d0=desc-sg[0] .. dN=desc-sg[N],
-     "f" stands for finisher and "l" for linker.
-     A typical running chain is :
-
-         Videobuffer 1         Videobuffer 2
-     +---------+----+---+  +----+----+----+---+
-     | d0 | .. | dN | l |  | d0 | .. | dN | f |
-     +---------+----+-|-+  ^----+----+----+---+
-                      |    |
-                      +----+
-
-     After the chaining is finished, the chain looks like :
-
-         Videobuffer 1         Videobuffer 2         Videobuffer 3
-     +---------+----+---+  +----+----+----+---+  +----+----+----+---+
-     | d0 | .. | dN | l |  | d0 | .. | dN | l |  | d0 | .. | dN | f |
-     +---------+----+-|-+  ^----+----+----+-|-+  ^----+----+----+---+
-                      |    |                |    |
-                      +----+                +----+
-                                           new_link
-
-  c) DMA hot chaining timeslice issue
-
-     As DMA chaining is done while DMA _is_ running, the linking may be done
-     while the DMA jumps from one Videobuffer to another. On the schema, that
-     would be a problem if the following sequence is encountered :
-
-      - DMA chain is Videobuffer1 + Videobuffer2
-      - pxa_videobuf_queue() is called to queue Videobuffer3
-      - DMA controller finishes Videobuffer2, and DMA stops
-      =>
-         Videobuffer 1         Videobuffer 2
-     +---------+----+---+  +----+----+----+---+
-     | d0 | .. | dN | l |  | d0 | .. | dN | f |
-     +---------+----+-|-+  ^----+----+----+-^-+
-                      |    |                |
-                      +----+                +-- DMA DDADR loads DDADR_STOP
-
-      - pxa_dma_add_tail_buf() is called, the Videobuffer2 "finisher" is
-        replaced by a "linker" to Videobuffer3 (creation of new_link)
-      - pxa_videobuf_queue() finishes
-      - the DMA irq handler is called, which terminates Videobuffer2
-      - Videobuffer3 capture is not scheduled on DMA chain (as it stopped !!!)
-
-         Videobuffer 1         Videobuffer 2         Videobuffer 3
-     +---------+----+---+  +----+----+----+---+  +----+----+----+---+
-     | d0 | .. | dN | l |  | d0 | .. | dN | l |  | d0 | .. | dN | f |
-     +---------+----+-|-+  ^----+----+----+-|-+  ^----+----+----+---+
-                      |    |                |    |
-                      +----+                +----+
-                                           new_link
-                                          DMA DDADR still is DDADR_STOP
-
-      - pxa_camera_check_link_miss() is called
-        This checks if the DMA is finished and a buffer is still on the
-        pcdev->capture list. If that's the case, the capture will be restarted,
-        and Videobuffer3 is scheduled on DMA chain.
-      - the DMA irq handler finishes
-
-     Note: if DMA stops just after pxa_camera_check_link_miss() reads DDADR()
-     value, we have the guarantee that the DMA irq handler will be called back
-     when the DMA will finish the buffer, and pxa_camera_check_link_miss() will
-     be called again, to reschedule Videobuffer3.

-NOTES ON RADIOTRACK CARD CONTROL
-by Stephen M. Benoit (benoits@servicepro.com)  Dec 14, 1996
-----------------------------------------------------------------------------
-
-Document version 1.0
-
-ACKNOWLEDGMENTS
-----------------
-This document was made based on 'C' code for Linux from Gideon le Grange
-(legrang@active.co.za or legrang@cs.sun.ac.za) in 1994, and elaborations from
-Frans Brinkman (brinkman@esd.nl) in 1996.  The results reported here are from
-experiments that the author performed on his own setup, so your mileage may
-vary... I make no guarantees, claims or warranties to the suitability or
-validity of this information.  No other documentation on the AIMS
-Lab (http://www.aimslab.com/) RadioTrack card was made available to the
-author.  This document is offered in the hopes that it might help users who
-want to use the RadioTrack card in an environment other than MS Windows.
-
-WHY THIS DOCUMENT?
-------------------
-I have a RadioTrack card from back when I ran an MS-Windows platform.  After
-converting to Linux, I found Gideon le Grange's command-line software for
-running the card, and found that it was good!  Frans Brinkman made a
-comfortable X-windows interface, and added a scanning feature.  For hack
-value, I wanted to see if the tuner could be tuned beyond the usual FM radio
-broadcast band, so I could pick up the audio carriers from North American
-broadcast TV channels, situated just below and above the 87.0-109.0 MHz range.
-I did not get much success, but I learned about programming ioports under
-Linux and gained some insights about the hardware design used for the card.
-
-So, without further delay, here are the details.
-
-
-PHYSICAL DESCRIPTION
---------------------
-The RadioTrack card is an ISA 8-bit FM radio card.  The radio frequency (RF)
-input is simply an antenna lead, and the output is a power audio signal
-available through a miniature phone plug.  Its RF frequencies of operation are
-more or less limited from 87.0 to 109.0 MHz (the commercial FM broadcast
-band).  Although the registers can be programmed to request frequencies beyond
-these limits, experiments did not give promising results.  The variable
-frequency oscillator (VFO) that demodulates the intermediate frequency (IF)
-signal probably has a small range of useful frequencies, and wraps around or
-gets clipped beyond the limits mentioned above.
-
-
-CONTROLLING THE CARD WITH IOPORT
---------------------------------
-The RadioTrack (base) ioport is configurable for 0x30c or 0x20c.  Only one
-ioport seems to be involved.  The ioport decoding circuitry must be pretty
-simple, as individual ioport bits are directly matched to specific functions
-(or blocks) of the radio card.  This way, many functions can be changed in
-parallel with one write to the ioport.  The only feedback available through
-the ioports appears to be the "Stereo Detect" bit.
-
-The bits of the ioport are arranged as follows:
-
-  MSb                                                         LSb
-+------+------+------+--------+--------+-------+---------+--------+
-| VolA | VolB | ???? | Stereo | Radio  | TuneA | TuneB   | Tune   |
-|  (+) |  (-) |      | Detect | Audio  | (bit) | (latch) | Update |
-|      |      |      | Enable | Enable |       |         | Enable |
-+------+------+------+--------+--------+-------+---------+--------+
-
-
-VolA . VolB  [AB......]
------------
-0 0 : audio mute
-0 1 : volume +    (some delay required)
-1 0 : volume -    (some delay required)
-1 1 : stay at present volume
-
-Stereo Detect Enable [...S....]
---------------------
-0 : No Detect
-1 : Detect
-
-  Results available by reading ioport >60 msec after last port write.
-  0xff ==> no stereo detected,  0xfd ==> stereo detected.
-
-Radio to Audio (path) Enable [....R...]
-----------------------------
-0 : Disable path (silence)
-1 : Enable path  (audio produced)
-
-TuneA . TuneB [.....AB.]
--------------
-0 0 : "zero" bit phase 1
-0 1 : "zero" bit phase 2
-
-1 0 : "one" bit phase 1
-1 1 : "one" bit phase 2
-
-  24-bit code, where bits = (freq*40) + 10486188.
-  The Most Significant 11 bits must be 1010 xxxx 0x0 to be valid.
-  The bits are shifted in LSb first.
-
-Tune Update Enable [.......T]
-------------------
-0 : Tuner held constant
-1 : Tuner updating in progress
-
-
-PROGRAMMING EXAMPLES
---------------------
-Default:        BASE <-- 0xc8  (current volume, no stereo detect,
-				radio enable, tuner adjust disable)
-
-Card Off:	BASE <-- 0x00  (audio mute, no stereo detect,
-				radio disable, tuner adjust disable)
-
-Card On:	BASE <-- 0x00  (see "Card Off", clears any unfinished business)
-		BASE <-- 0xc8  (see "Default")
-
-Volume Down:    BASE <-- 0x48  (volume down, no stereo detect,

-In the above chart minuses and slashes represent "real" data amounts, points and
-accents represent "useful" data, basically, CEU scaled and cropped output,
-mapped back onto the client's source plane.
-
-Such a configuration can be produced by user requests:
-
-S_CROP(left / top = (5) - (1), width / height = (5') - (5))
-S_FMT(width / height = (6') - (6))
-
-Here:
-
-(1) to (1') - whole max width or height
-(1) to (2)  - sensor cropped left or top
-(2) to (2') - sensor cropped width or height
-(3) to (3') - sensor scale
-(3) to (4)  - CEU cropped left or top
-(4) to (4') - CEU cropped width or height
-(5) to (5') - reverse sensor scale applied to CEU cropped width or height
-(2) to (5)  - reverse sensor scale applied to CEU cropped left or top
-(6) to (6') - CEU scale - user window
-
-
-S_FMT
------
-
-Do not touch input rectangle - it is already optimal.
-
-1. Calculate current sensor scales:
-
-	scale_s = ((2') - (2)) / ((3') - (3))
-
-2. Calculate "effective" input crop (sensor subwindow) - CEU crop scaled back at
-current sensor scales onto input window - this is user S_CROP:
-
-	width_u = (5') - (5) = ((4') - (4)) * scale_s
-
-3. Calculate new combined scales from "effective" input window to requested user
-window:
-
-	scale_comb = width_u / ((6') - (6))
-
-4. Calculate sensor output window by applying combined scales to real input
-window:
-
-	width_s_out = ((7') - (7)) = ((2') - (2)) / scale_comb
-
-5. Apply iterative sensor S_FMT for sensor output window.
-
-	subdev->video_ops->s_fmt(.width = width_s_out)
-
-6. Retrieve sensor output window (g_fmt)
-
-7. Calculate new sensor scales:
-
-	scale_s_new = ((3')_new - (3)_new) / ((2') - (2))
-
-8. Calculate new CEU crop - apply sensor scales to previously calculated
-"effective" crop:
-
-	width_ceu = (4')_new - (4)_new = width_u / scale_s_new
-	left_ceu = (4)_new - (3)_new = ((5) - (2)) / scale_s_new
-
-9. Use CEU cropping to crop to the new window:
-
-	ceu_crop(.width = width_ceu, .left = left_ceu)
-
-10. Use CEU scaling to scale to the requested user window:
-
-	scale_ceu = width_ceu / width
-
-
-S_CROP
-------
-
-The API at http://v4l2spec.bytesex.org/spec/x1904.htm says:
-
-"...specification does not define an origin or units. However by convention
-drivers should horizontally count unscaled samples relative to 0H."
-
-We choose to follow the advise and interpret cropping units as client input
-pixels.
-
-Cropping is performed in the following 6 steps:
-
-1. Request exactly user rectangle from the sensor.
-
-2. If smaller - iterate until a larger one is obtained. Result: sensor cropped
-   to 2 : 2', target crop 5 : 5', current output format 6' - 6.
-
-3. In the previous step the sensor has tried to preserve its output frame as
-   good as possible, but it could have changed. Retrieve it again.
-
-4. Sensor scaled to 3 : 3'. Sensor's scale is (2' - 2) / (3' - 3). Calculate
-   intermediate window: 4' - 4 = (5' - 5) * (3' - 3) / (2' - 2)
-
-5. Calculate and apply host scale = (6' - 6) / (4' - 4)
-
-6. Calculate and apply host crop: 6 - 7 = (5 - 2) * (6' - 6) / (5' - 5)

-Driver for USB radios for the Silicon Labs Si470x FM Radio Receivers
-
-Copyright (c) 2009 Tobias Lorenz <tobias.lorenz@gmx.net>
-
-
-Information from Silicon Labs
-=============================
-Silicon Laboratories is the manufacturer of the radio ICs, that nowadays are the
-most often used radio receivers in cell phones. Usually they are connected with
-I2C. But SiLabs also provides a reference design, which integrates this IC,
-together with a small microcontroller C8051F321, to form a USB radio.
-Part of this reference design is also a radio application in binary and source
-code. The software also contains an automatic firmware upgrade to the most
-current version. Information on these can be downloaded here:
-http://www.silabs.com/usbradio
-
-
-Supported ICs
-=============
-The following ICs have a very similar register set, so that they are or will be
-supported somewhen by the driver:
-- Si4700: FM radio receiver
-- Si4701: FM radio receiver, RDS Support
-- Si4702: FM radio receiver
-- Si4703: FM radio receiver, RDS Support
-- Si4704: FM radio receiver, no external antenna required
-- Si4705: FM radio receiver, no external antenna required, RDS support, Dig I/O
-- Si4706: Enhanced FM RDS/TMC radio receiver, no external antenna required, RDS
-	  Support
-- Si4707: Dedicated weather band radio receiver with SAME decoder, RDS Support
-- Si4708: Smallest FM receivers
-- Si4709: Smallest FM receivers, RDS Support
-More information on these can be downloaded here:
-http://www.silabs.com/products/mcu/Pages/USBFMRadioRD.aspx
-
-
-Supported USB devices
-=====================
-Currently the following USB radios (vendor:product) with the Silicon Labs si470x
-chips are known to work:
-- 10c4:818a: Silicon Labs USB FM Radio Reference Design
-- 06e1:a155: ADS/Tech FM Radio Receiver (formerly Instant FM Music) (RDX-155-EF)
-- 1b80:d700: KWorld USB FM Radio SnapMusic Mobile 700 (FM700)
-- 10c5:819a: Sanei Electric, Inc. FM USB Radio (sold as DealExtreme.com PCear)
-
-
-Software
-========
-Testing is usually done with most application under Debian/testing:
-- fmtools - Utility for managing FM tuner cards
-- gnomeradio - FM-radio tuner for the GNOME desktop
-- gradio - GTK FM radio tuner
-- kradio - Comfortable Radio Application for KDE
-- radio - ncurses-based radio application
-- mplayer - The Ultimate Movie Player For Linux
-- v4l2-ctl - Collection of command line video4linux utilities
-For example, you can use:
-v4l2-ctl -d /dev/radio0 --set-ctrl=volume=10,mute=0 --set-freq=95.21 --all
-
-There is also a library libv4l, which can be used. It's going to have a function
-for frequency seeking, either by using hardware functionality as in radio-si470x
-or by implementing a function as we currently have in every of the mentioned
-programs. Somewhen the radio programs should make use of libv4l.
-
-For processing RDS information, there is a project ongoing at:
-http://rdsd.berlios.de/
-
-There is currently no project for making TMC sentences human readable.
-
-
-Audio Listing
-=============
-USB Audio is provided by the ALSA snd_usb_audio module. It is recommended to
-also select SND_USB_AUDIO, as this is required to get sound from the radio. For
-listing you have to redirect the sound, for example using one of the following
-commands. Please adjust the audio devices to your needs (/dev/dsp* and hw:x,x).
-
-If you just want to test audio (very poor quality):
-cat /dev/dsp1 > /dev/dsp
-
-If you use sox + OSS try:
-sox -2 --endian little -r 96000 -t oss /dev/dsp1 -t oss /dev/dsp
-or using sox + alsa:
-sox --endian little -c 2 -S -r 96000 -t alsa hw:1 -t alsa -r 96000 hw:0
-
-If you use arts try:
-arecord -D hw:1,0 -r96000 -c2 -f S16_LE | artsdsp aplay -B -
-
-If you use mplayer try:
-mplayer -radio adevice=hw=1.0:arate=96000 \
-	-rawaudio rate=96000 \
-	radio://<frequency>/capture
-
-Module Parameters
-=================
-After loading the module, you still have access to some of them in the sysfs
-mount under /sys/module/radio_si470x/parameters. The contents of read-only files
-(0444) are not updated, even if space, band and de are changed using private
-video controls. The others are runtime changeable.
-
-
-Errors
-======
-Increase tune_timeout, if you often get -EIO errors.
-
-When timed out or band limit is reached, hw_freq_seek returns -EAGAIN.
-
-If you get any errors from snd_usb_audio, please report them to the ALSA people.
-
-
-Open Issues
-===========
-V4L minor device allocation and parameter setting is not perfect. A solution is
-currently under discussion.
-
-There is an USB interface for downloading/uploading new firmware images. Support
-for it can be implemented using the request_firmware interface.
-
-There is a RDS interrupt mode. The driver is already using the same interface
-for polling RDS information, but is currently not using the interrupt mode.
-
-There is a LED interface, which can be used to override the LED control
-programmed in the firmware. This can be made available using the LED support
-functions in the kernel.

-Driver for I2C radios for the Silicon Labs Si4713 FM Radio Transmitters
-
-Copyright (c) 2009 Nokia Corporation
-Contact: Eduardo Valentin <eduardo.valentin@nokia.com>
-
-
-Information about the Device
-============================
-This chip is a Silicon Labs product. It is a I2C device, currently on 0x63 address.
-Basically, it has transmission and signal noise level measurement features.
-
-The Si4713 integrates transmit functions for FM broadcast stereo transmission.
-The chip also allows integrated receive power scanning to identify low signal
-power FM channels.
-
-The chip is programmed using commands and responses. There are also several
-properties which can change the behavior of this chip.
-
-Users must comply with local regulations on radio frequency (RF) transmission.
-
-Device driver description
-=========================
-There are two modules to handle this device. One is a I2C device driver
-and the other is a platform driver.
-
-The I2C device driver exports a v4l2-subdev interface to the kernel.
-All properties can also be accessed by v4l2 extended controls interface, by
-using the v4l2-subdev calls (g_ext_ctrls, s_ext_ctrls).
-
-The platform device driver exports a v4l2 radio device interface to user land.
-So, it uses the I2C device driver as a sub device in order to send the user
-commands to the actual device. Basically it is a wrapper to the I2C device driver.
-
-Applications can use v4l2 radio API to specify frequency of operation, mute state,
-etc. But mostly of its properties will be present in the extended controls.
-
-When the v4l2 mute property is set to 1 (true), the driver will turn the chip off.
-
-Properties description
-======================
-
-The properties can be accessed using v4l2 extended controls.
-Here is an output from v4l2-ctl util:

-/ #
-
-Here is a summary of them:
-
-* Pilot is an audible tone sent by the device.
-
-pilot_frequency - Configures the frequency of the stereo pilot tone.
-pilot_deviation - Configures pilot tone frequency deviation level.
-pilot_enabled - Enables or disables the pilot tone feature.
-
-* The si4713 device is capable of applying audio compression to the transmitted signal.
-
-acomp_enabled - Enables or disables the audio dynamic range control feature.
-acomp_gain - Sets the gain for audio dynamic range control.
-acomp_threshold - Sets the threshold level for audio dynamic range control.
-acomp_attack_time - Sets the attack time for audio dynamic range control.
-acomp_release_time - Sets the release time for audio dynamic range control.
-
-* Limiter setups audio deviation limiter feature. Once a over deviation occurs,
-it is possible to adjust the front-end gain of the audio input and always
-prevent over deviation.
-
-limiter_enabled - Enables or disables the limiter feature.
-limiter_deviation - Configures audio frequency deviation level.
-limiter_release_time - Sets the limiter release time.
-
-* Tuning power
-
-power_level - Sets the output power level for signal transmission.
-antenna_capacitor - This selects the value of antenna tuning capacitor manually
-or automatically if set to zero.
-
-* RDS related
-
-rds_ps_name - Sets the RDS ps name field for transmission.
-rds_radio_text - Sets the RDS radio text for transmission.
-rds_pi - Sets the RDS PI field for transmission.
-rds_pty - Sets the RDS PTY field for transmission.
-
-* Region related
-
-preemphasis - sets the preemphasis to be applied for transmission.
-
-RNL
-===
-
-This device also has an interface to measure received noise level. To do that, you should
-ioctl the device node. Here is an code of example:
-
-int main (int argc, char *argv[])
-{
-	struct si4713_rnl rnl;
-	int fd = open("/dev/radio0", O_RDWR);
-	int rval;
-
-	if (argc < 2)
-		return -EINVAL;
-
-	if (fd < 0)
-		return fd;
-
-	sscanf(argv[1], "%d", &rnl.frequency);
-
-	rval = ioctl(fd, SI4713_IOC_MEASURE_RNL, &rnl);
-	if (rval < 0)
-		return rval;
-
-	printf("received noise level: %d\n", rnl.rnl);
-
-	close(fd);
-}
-
-The struct si4713_rnl and SI4713_IOC_MEASURE_RNL are defined under
-include/linux/platform_data/media/si4713.h.
-
-Stereo/Mono and RDS subchannels
-===============================
-
-The device can also be configured using the available sub channels for
-transmission. To do that use S/G_MODULATOR ioctl and configure txsubchans properly.
-Refer to the V4L2 API specification for proper use of this ioctl.
-
-Testing
-=======
-Testing is usually done with v4l2-ctl utility for managing FM tuner cards.
-The tool can be found in v4l-dvb repository under v4l2-apps/util directory.
-
-Example for setting rds ps name:
-# v4l2-ctl -d /dev/radio0 --set-ctrl=rds_ps_name="Dummy"

-SI476x Driver Readme
-------------------------------------------------
-	Copyright (C) 2013 Andrey Smirnov <andrew.smirnov@gmail.com>
-
-TODO for the driver
-------------------------------
-
-- According to the SiLabs' datasheet it is possible to update the
-  firmware of the radio chip in the run-time, thus bringing it to the
-  most recent version. Unfortunately I couldn't find any mentioning of
-  the said firmware update for the old chips that I tested the driver
-  against, so for chips like that the driver only exposes the old
-  functionality.
-
-
-Parameters exposed over debugfs
--------------------------------
-SI476x allow user to get multiple characteristics that can be very
-useful for EoL testing/RF performance estimation, parameters that have
-very little to do with V4L2 subsystem. Such parameters are exposed via
-debugfs and can be accessed via regular file I/O operations.
-
-The drivers exposes following files:
-
-* /sys/kernel/debug/<device-name>/acf
-  This file contains ACF(Automatically Controlled Features) status
-  information. The contents of the file is binary data of the

-			Soc-Camera Subsystem
-			====================
-
-Terminology
------------
-
-The following terms are used in this document:
- - camera / camera device / camera sensor - a video-camera sensor chip, capable
-   of connecting to a variety of systems and interfaces, typically uses i2c for
-   control and configuration, and a parallel or a serial bus for data.
- - camera host - an interface, to which a camera is connected. Typically a
-   specialised interface, present on many SoCs, e.g. PXA27x and PXA3xx, SuperH,
-   AVR32, i.MX27, i.MX31.
- - camera host bus - a connection between a camera host and a camera. Can be
-   parallel or serial, consists of data and control lines, e.g. clock, vertical
-   and horizontal synchronization signals.
-
-Purpose of the soc-camera subsystem
------------------------------------
-
-The soc-camera subsystem initially provided a unified API between camera host
-drivers and camera sensor drivers. Later the soc-camera sensor API has been
-replaced with the V4L2 standard subdev API. This also made camera driver re-use
-with non-soc-camera hosts possible. The camera host API to the soc-camera core
-has been preserved.
-
-Soc-camera implements a V4L2 interface to the user, currently only the "mmap"
-method is supported by host drivers. However, the soc-camera core also provides
-support for the "read" method.
-
-The subsystem has been designed to support multiple camera host interfaces and
-multiple cameras per interface, although most applications have only one camera
-sensor.
-
-Existing drivers
-----------------
-
-As of 3.7 there are seven host drivers in the mainline: atmel-isi.c,
-mx1_camera.c (broken, scheduled for removal), mx2_camera.c, mx3_camera.c,
-omap1_camera.c, pxa_camera.c, sh_mobile_ceu_camera.c, and multiple sensor
-drivers under drivers/media/i2c/soc_camera/.
-
-Camera host API
----------------
-
-A host camera driver is registered using the
-
-soc_camera_host_register(struct soc_camera_host *);
-
-function. The host object can be initialized as follows:
-
-	struct soc_camera_host	*ici;
-	ici->drv_name		= DRV_NAME;
-	ici->ops		= &camera_host_ops;
-	ici->priv		= pcdev;
-	ici->v4l2_dev.dev	= &pdev->dev;
-	ici->nr			= pdev->id;
-
-All camera host methods are passed in a struct soc_camera_host_ops:
-
-static struct soc_camera_host_ops camera_host_ops = {
-	.owner		= THIS_MODULE,
-	.add		= camera_add_device,
-	.remove		= camera_remove_device,
-	.set_fmt	= camera_set_fmt_cap,
-	.try_fmt	= camera_try_fmt_cap,
-	.init_videobuf2	= camera_init_videobuf2,
-	.poll		= camera_poll,
-	.querycap	= camera_querycap,
-	.set_bus_param	= camera_set_bus_param,
-	/* The rest of host operations are optional */
-};
-
-.add and .remove methods are called when a sensor is attached to or detached
-from the host. .set_bus_param is used to configure physical connection
-parameters between the host and the sensor. .init_videobuf2 is called by
-soc-camera core when a video-device is opened, the host driver would typically
-call vb2_queue_init() in this method. Further video-buffer management is
-implemented completely by the specific camera host driver. If the host driver
-supports non-standard pixel format conversion, it should implement a
-.get_formats and, possibly, a .put_formats operations. See below for more
-details about format conversion. The rest of the methods are called from
-respective V4L2 operations.
-
-Camera API
-----------
-
-Sensor drivers can use struct soc_camera_link, typically provided by the
-platform, and used to specify to which camera host bus the sensor is connected,
-and optionally provide platform .power and .reset methods for the camera. This
-struct is provided to the camera driver via the I2C client device platform data
-and can be obtained, using the soc_camera_i2c_to_link() macro. Care should be
-taken, when using soc_camera_vdev_to_subdev() and when accessing struct
-soc_camera_device, using v4l2_get_subdev_hostdata(): both only work, when
-running on an soc-camera host. The actual camera driver operation is implemented
-using the V4L2 subdev API. Additionally soc-camera camera drivers can use
-auxiliary soc-camera helper functions like soc_camera_power_on() and
-soc_camera_power_off(), which switch regulators, provided by the platform and call
-board-specific power switching methods. soc_camera_apply_board_flags() takes
-camera bus configuration capability flags and applies any board transformations,
-e.g. signal polarity inversion. soc_mbus_get_fmtdesc() can be used to obtain a
-pixel format descriptor, corresponding to a certain media-bus pixel format code.
-soc_camera_limit_side() can be used to restrict beginning and length of a frame
-side, based on camera capabilities.
-
-VIDIOC_S_CROP and VIDIOC_S_FMT behaviour
-----------------------------------------
-
-Above user ioctls modify image geometry as follows:
-
-VIDIOC_S_CROP: sets location and sizes of the sensor window. Unit is one sensor
-pixel. Changing sensor window sizes preserves any scaling factors, therefore
-user window sizes change as well.
-
-VIDIOC_S_FMT: sets user window. Should preserve previously set sensor window as
-much as possible by modifying scaling factors. If the sensor window cannot be
-preserved precisely, it may be changed too.
-
-In soc-camera there are two locations, where scaling and cropping can take
-place: in the camera driver and in the host driver. User ioctls are first passed
-to the host driver, which then generally passes them down to the camera driver.
-It is more efficient to perform scaling and cropping in the camera driver to
-save camera bus bandwidth and maximise the framerate. However, if the camera
-driver failed to set the required parameters with sufficient precision, the host
-driver may decide to also use its own scaling and cropping to fulfill the user's
-request.
-
-Camera drivers are interfaced to the soc-camera core and to host drivers over
-the v4l2-subdev API, which is completely functional, it doesn't pass any data.
-Therefore all camera drivers shall reply to .g_fmt() requests with their current
-output geometry. This is necessary to correctly configure the camera bus.
-.s_fmt() and .try_fmt() have to be implemented too. Sensor window and scaling
-factors have to be maintained by camera drivers internally. According to the
-V4L2 API all capture drivers must support the VIDIOC_CROPCAP ioctl, hence we
-rely on camera drivers implementing .cropcap(). If the camera driver does not
-support cropping, it may choose to not implement .s_crop(), but to enable
-cropping support by the camera host driver at least the .g_crop method must be
-implemented.
-
-User window geometry is kept in .user_width and .user_height fields in struct
-soc_camera_device and used by the soc-camera core and host drivers. The core
-updates these fields upon successful completion of a .s_fmt() call, but if these
-fields change elsewhere, e.g. during .s_crop() processing, the host driver is
-responsible for updating them.
-
-Format conversion
------------------
-
-V4L2 distinguishes between pixel formats, as they are stored in memory, and as
-they are transferred over a media bus. Soc-camera provides support to
-conveniently manage these formats. A table of standard transformations is
-maintained by soc-camera core, which describes, what FOURCC pixel format will
-be obtained, if a media-bus pixel format is stored in memory according to
-certain rules. E.g. if MEDIA_BUS_FMT_YUYV8_2X8 data is sampled with 8 bits per
-sample and stored in memory in the little-endian order with no gaps between
-bytes, data in memory will represent the V4L2_PIX_FMT_YUYV FOURCC format. These
-standard transformations will be used by soc-camera or by camera host drivers to
-configure camera drivers to produce the FOURCC format, requested by the user,
-using the VIDIOC_S_FMT ioctl(). Apart from those standard format conversions,
-host drivers can also provide their own conversion rules by implementing a
-.get_formats and, if required, a .put_formats methods.

-Linux USB Video Class (UVC) driver
-==================================
-
-This file documents some driver-specific aspects of the UVC driver, such as
-driver-specific ioctls and implementation notes.
-
-Questions and remarks can be sent to the Linux UVC development mailing list at
-linux-uvc-devel@lists.berlios.de.
-
-
-Extension Unit (XU) support
----------------------------
-
-1. Introduction
-
-The UVC specification allows for vendor-specific extensions through extension
-units (XUs). The Linux UVC driver supports extension unit controls (XU controls)
-through two separate mechanisms:
-
-  - through mappings of XU controls to V4L2 controls
-  - through a driver-specific ioctl interface
-
-The first one allows generic V4L2 applications to use XU controls by mapping
-certain XU controls onto V4L2 controls, which then show up during ordinary
-control enumeration.
-
-The second mechanism requires uvcvideo-specific knowledge for the application to
-access XU controls but exposes the entire UVC XU concept to user space for
-maximum flexibility.
-
-Both mechanisms complement each other and are described in more detail below.
-
-
-2. Control mappings
-
-The UVC driver provides an API for user space applications to define so-called
-control mappings at runtime. These allow for individual XU controls or byte
-ranges thereof to be mapped to new V4L2 controls. Such controls appear and
-function exactly like normal V4L2 controls (i.e. the stock controls, such as
-brightness, contrast, etc.). However, reading or writing of such a V4L2 controls
-triggers a read or write of the associated XU control.
-
-The ioctl used to create these control mappings is called UVCIOC_CTRL_MAP.
-Previous driver versions (before 0.2.0) required another ioctl to be used
-beforehand (UVCIOC_CTRL_ADD) to pass XU control information to the UVC driver.
-This is no longer necessary as newer uvcvideo versions query the information
-directly from the device.
-
-For details on the UVCIOC_CTRL_MAP ioctl please refer to the section titled
-"IOCTL reference" below.
-
-
-3. Driver specific XU control interface
-
-For applications that need to access XU controls directly, e.g. for testing
-purposes, firmware upload, or accessing binary controls, a second mechanism to
-access XU controls is provided in the form of a driver-specific ioctl, namely
-UVCIOC_CTRL_QUERY.
-
-A call to this ioctl allows applications to send queries to the UVC driver that
-directly map to the low-level UVC control requests.
-
-In order to make such a request the UVC unit ID of the control's extension unit
-and the control selector need to be known. This information either needs to be
-hardcoded in the application or queried using other ways such as by parsing the
-UVC descriptor or, if available, using the media controller API to enumerate a
-device's entities.
-
-Unless the control size is already known it is necessary to first make a
-UVC_GET_LEN requests in order to be able to allocate a sufficiently large buffer
-and set the buffer size to the correct value. Similarly, to find out whether
-UVC_GET_CUR or UVC_SET_CUR are valid requests for a given control, a
-UVC_GET_INFO request should be made. The bits 0 (GET supported) and 1 (SET
-supported) of the resulting byte indicate which requests are valid.
-
-With the addition of the UVCIOC_CTRL_QUERY ioctl the UVCIOC_CTRL_GET and
-UVCIOC_CTRL_SET ioctls have become obsolete since their functionality is a
-subset of the former ioctl. For the time being they are still supported but
-application developers are encouraged to use UVCIOC_CTRL_QUERY instead.
-
-For details on the UVCIOC_CTRL_QUERY ioctl please refer to the section titled
-"IOCTL reference" below.
-
-
-4. Security
-
-The API doesn't currently provide a fine-grained access control facility. The
-UVCIOC_CTRL_ADD and UVCIOC_CTRL_MAP ioctls require super user permissions.
-
-Suggestions on how to improve this are welcome.
-
-
-5. Debugging
-
-In order to debug problems related to XU controls or controls in general it is
-recommended to enable the UVC_TRACE_CONTROL bit in the module parameter 'trace'.
-This causes extra output to be written into the system log.
-
-
-6. IOCTL reference
-
----- UVCIOC_CTRL_MAP - Map a UVC control to a V4L2 control ----
-
-Argument: struct uvc_xu_control_mapping
-
-Description:
-	This ioctl creates a mapping between a UVC control or part of a UVC
-	control and a V4L2 control. Once mappings are defined, userspace
-	applications can access vendor-defined UVC control through the V4L2
-	control API.
-
-	To create a mapping, applications fill the uvc_xu_control_mapping
-	structure with information about an existing UVC control defined with
-	UVCIOC_CTRL_ADD and a new V4L2 control.
-
-	A UVC control can be mapped to several V4L2 controls. For instance,
-	a UVC pan/tilt control could be mapped to separate pan and tilt V4L2
-	controls. The UVC control is divided into non overlapping fields using
-	the 'size' and 'offset' fields and are then independently mapped to
-	V4L2 control.
-
-	For signed integer V4L2 controls the data_type field should be set to
-	UVC_CTRL_DATA_TYPE_SIGNED. Other values are currently ignored.
-
-Return value:
-	On success 0 is returned. On error -1 is returned and errno is set
-	appropriately.
-
-	ENOMEM
-		Not enough memory to perform the operation.
-	EPERM
-		Insufficient privileges (super user privileges are required).
-	EINVAL
-		No such UVC control.
-	EOVERFLOW
-		The requested offset and size would overflow the UVC control.
-	EEXIST
-		Mapping already exists.

-
-	* struct uvc_menu_info
-
-	__u32	value		Menu entry value used by the device
-	__u8	name[32]	Menu entry name
-

-	UVC_CTRL_DATA_TYPE_BOOLEAN	Boolean
-	UVC_CTRL_DATA_TYPE_ENUM		Enumeration
-	UVC_CTRL_DATA_TYPE_BITMASK	Bitmask
-
-
----- UVCIOC_CTRL_QUERY - Query a UVC XU control ----
-
-Argument: struct uvc_xu_control_query
-
-Description:
-	This ioctl queries a UVC XU control identified by its extension unit ID
-	and control selector.
-
-	There are a number of different queries available that closely
-	correspond to the low-level control requests described in the UVC
-	specification. These requests are:
-
-	UVC_GET_CUR
-		Obtain the current value of the control.
-	UVC_GET_MIN
-		Obtain the minimum value of the control.
-	UVC_GET_MAX
-		Obtain the maximum value of the control.
-	UVC_GET_DEF
-		Obtain the default value of the control.
-	UVC_GET_RES
-		Query the resolution of the control, i.e. the step size of the
-		allowed control values.
-	UVC_GET_LEN
-		Query the size of the control in bytes.
-	UVC_GET_INFO
-		Query the control information bitmap, which indicates whether
-		get/set requests are supported.
-	UVC_SET_CUR
-		Update the value of the control.
-
-	Applications must set the 'size' field to the correct length for the
-	control. Exceptions are the UVC_GET_LEN and UVC_GET_INFO queries, for
-	which the size must be set to 2 and 1, respectively. The 'data' field
-	must point to a valid writable buffer big enough to hold the indicated
-	number of data bytes.
-
-	Data is copied directly from the device without any driver-side
-	processing. Applications are responsible for data buffer formatting,
-	including little-endian/big-endian conversion. This is particularly
-	important for the result of the UVC_GET_LEN requests, which is always
-	returned as a little-endian 16-bit integer by the device.
-
-Return value:
-	On success 0 is returned. On error -1 is returned and errno is set
-	appropriately.
-
-	ENOENT
-		The device does not support the given control or the specified
-		extension unit could not be found.
-	ENOBUFS
-		The specified buffer size is incorrect (too big or too small).
-	EINVAL
-		An invalid request code was passed.
-	EBADRQC
-		The given request is not supported by the given control.
-	EFAULT
-		The data pointer references an inaccessible memory area.
-
-Data types:
-	* struct uvc_xu_control_query
-
-	__u8	unit		Extension unit ID
-	__u8	selector	Control selector
-	__u8	query		Request code to send to the device
-	__u16	size		Control data size (in bytes)
-	__u8	*data		Control value

-Introduction
-============
-
-The V4L2 control API seems simple enough, but quickly becomes very hard to
-implement correctly in drivers. But much of the code needed to handle controls
-is actually not driver specific and can be moved to the V4L core framework.
-
-After all, the only part that a driver developer is interested in is:
-
-1) How do I add a control?
-2) How do I set the control's value? (i.e. s_ctrl)
-
-And occasionally:
-
-3) How do I get the control's value? (i.e. g_volatile_ctrl)
-4) How do I validate the user's proposed control value? (i.e. try_ctrl)
-
-All the rest is something that can be done centrally.
-
-The control framework was created in order to implement all the rules of the
-V4L2 specification with respect to controls in a central place. And to make
-life as easy as possible for the driver developer.
-
-Note that the control framework relies on the presence of a struct v4l2_device
-for V4L2 drivers and struct v4l2_subdev for sub-device drivers.
-
-
-Objects in the framework
-========================
-
-There are two main objects:
-
-The v4l2_ctrl object describes the control properties and keeps track of the
-control's value (both the current value and the proposed new value).
-
-v4l2_ctrl_handler is the object that keeps track of controls. It maintains a
-list of v4l2_ctrl objects that it owns and another list of references to
-controls, possibly to controls owned by other handlers.
-
-
-Basic usage for V4L2 and sub-device drivers
-===========================================
-
-1) Prepare the driver:
-
-1.1) Add the handler to your driver's top-level struct:
-
-	struct foo_dev {
-		...
-		struct v4l2_ctrl_handler ctrl_handler;
-		...
-	};
-
-	struct foo_dev *foo;
-
-1.2) Initialize the handler:
-
-	v4l2_ctrl_handler_init(&foo->ctrl_handler, nr_of_controls);
-
-  The second argument is a hint telling the function how many controls this
-  handler is expected to handle. It will allocate a hashtable based on this
-  information. It is a hint only.
-
-1.3) Hook the control handler into the driver:
-
-1.3.1) For V4L2 drivers do this:
-
-	struct foo_dev {
-		...
-		struct v4l2_device v4l2_dev;
-		...
-		struct v4l2_ctrl_handler ctrl_handler;
-		...
-	};
-
-	foo->v4l2_dev.ctrl_handler = &foo->ctrl_handler;
-
-  Where foo->v4l2_dev is of type struct v4l2_device.
-
-  Finally, remove all control functions from your v4l2_ioctl_ops (if any):
-  vidioc_queryctrl, vidioc_query_ext_ctrl, vidioc_querymenu, vidioc_g_ctrl,
-  vidioc_s_ctrl, vidioc_g_ext_ctrls, vidioc_try_ext_ctrls and vidioc_s_ext_ctrls.
-  Those are now no longer needed.
-
-1.3.2) For sub-device drivers do this:
-
-	struct foo_dev {
-		...
-		struct v4l2_subdev sd;
-		...
-		struct v4l2_ctrl_handler ctrl_handler;
-		...
-	};
-
-	foo->sd.ctrl_handler = &foo->ctrl_handler;
-
-  Where foo->sd is of type struct v4l2_subdev.
-
-  And set all core control ops in your struct v4l2_subdev_core_ops to these
-  helpers:
-
-	.queryctrl = v4l2_subdev_queryctrl,
-	.querymenu = v4l2_subdev_querymenu,
-	.g_ctrl = v4l2_subdev_g_ctrl,
-	.s_ctrl = v4l2_subdev_s_ctrl,
-	.g_ext_ctrls = v4l2_subdev_g_ext_ctrls,
-	.try_ext_ctrls = v4l2_subdev_try_ext_ctrls,
-	.s_ext_ctrls = v4l2_subdev_s_ext_ctrls,
-
-  Note: this is a temporary solution only. Once all V4L2 drivers that depend
-  on subdev drivers are converted to the control framework these helpers will
-  no longer be needed.
-
-1.4) Clean up the handler at the end:
-
-	v4l2_ctrl_handler_free(&foo->ctrl_handler);
-
-
-2) Add controls:
-
-You add non-menu controls by calling v4l2_ctrl_new_std:
-
-	struct v4l2_ctrl *v4l2_ctrl_new_std(struct v4l2_ctrl_handler *hdl,
-			const struct v4l2_ctrl_ops *ops,
-			u32 id, s32 min, s32 max, u32 step, s32 def);
-
-Menu and integer menu controls are added by calling v4l2_ctrl_new_std_menu:
-
-	struct v4l2_ctrl *v4l2_ctrl_new_std_menu(struct v4l2_ctrl_handler *hdl,
-			const struct v4l2_ctrl_ops *ops,
-			u32 id, s32 max, s32 skip_mask, s32 def);
-
-Menu controls with a driver specific menu are added by calling
-v4l2_ctrl_new_std_menu_items:
-
-       struct v4l2_ctrl *v4l2_ctrl_new_std_menu_items(
-                       struct v4l2_ctrl_handler *hdl,
-                       const struct v4l2_ctrl_ops *ops, u32 id, s32 max,
-                       s32 skip_mask, s32 def, const char * const *qmenu);
-
-Integer menu controls with a driver specific menu can be added by calling
-v4l2_ctrl_new_int_menu:
-
-	struct v4l2_ctrl *v4l2_ctrl_new_int_menu(struct v4l2_ctrl_handler *hdl,
-			const struct v4l2_ctrl_ops *ops,
-			u32 id, s32 max, s32 def, const s64 *qmenu_int);
-
-These functions are typically called right after the v4l2_ctrl_handler_init:
-
-	static const s64 exp_bias_qmenu[] = {
-	       -2, -1, 0, 1, 2
-	};
-	static const char * const test_pattern[] = {
-		"Disabled",
-		"Vertical Bars",
-		"Solid Black",
-		"Solid White",
-	};
-
-	v4l2_ctrl_handler_init(&foo->ctrl_handler, nr_of_controls);
-	v4l2_ctrl_new_std(&foo->ctrl_handler, &foo_ctrl_ops,
-			V4L2_CID_BRIGHTNESS, 0, 255, 1, 128);
-	v4l2_ctrl_new_std(&foo->ctrl_handler, &foo_ctrl_ops,
-			V4L2_CID_CONTRAST, 0, 255, 1, 128);
-	v4l2_ctrl_new_std_menu(&foo->ctrl_handler, &foo_ctrl_ops,
-			V4L2_CID_POWER_LINE_FREQUENCY,
-			V4L2_CID_POWER_LINE_FREQUENCY_60HZ, 0,
-			V4L2_CID_POWER_LINE_FREQUENCY_DISABLED);
-	v4l2_ctrl_new_int_menu(&foo->ctrl_handler, &foo_ctrl_ops,
-			V4L2_CID_EXPOSURE_BIAS,
-			ARRAY_SIZE(exp_bias_qmenu) - 1,
-			ARRAY_SIZE(exp_bias_qmenu) / 2 - 1,
-			exp_bias_qmenu);
-	v4l2_ctrl_new_std_menu_items(&foo->ctrl_handler, &foo_ctrl_ops,
-			V4L2_CID_TEST_PATTERN, ARRAY_SIZE(test_pattern) - 1, 0,
-			0, test_pattern);
-	...
-	if (foo->ctrl_handler.error) {
-		int err = foo->ctrl_handler.error;
-
-		v4l2_ctrl_handler_free(&foo->ctrl_handler);
-		return err;
-	}
-
-The v4l2_ctrl_new_std function returns the v4l2_ctrl pointer to the new
-control, but if you do not need to access the pointer outside the control ops,
-then there is no need to store it.
-
-The v4l2_ctrl_new_std function will fill in most fields based on the control
-ID except for the min, max, step and default values. These are passed in the
-last four arguments. These values are driver specific while control attributes
-like type, name, flags are all global. The control's current value will be set
-to the default value.
-
-The v4l2_ctrl_new_std_menu function is very similar but it is used for menu
-controls. There is no min argument since that is always 0 for menu controls,
-and instead of a step there is a skip_mask argument: if bit X is 1, then menu
-item X is skipped.
-
-The v4l2_ctrl_new_int_menu function creates a new standard integer menu
-control with driver-specific items in the menu. It differs from
-v4l2_ctrl_new_std_menu in that it doesn't have the mask argument and takes
-as the last argument an array of signed 64-bit integers that form an exact
-menu item list.
-
-The v4l2_ctrl_new_std_menu_items function is very similar to
-v4l2_ctrl_new_std_menu but takes an extra parameter qmenu, which is the driver
-specific menu for an otherwise standard menu control. A good example for this
-control is the test pattern control for capture/display/sensors devices that
-have the capability to generate test patterns. These test patterns are hardware
-specific, so the contents of the menu will vary from device to device.
-
-Note that if something fails, the function will return NULL or an error and
-set ctrl_handler->error to the error code. If ctrl_handler->error was already
-set, then it will just return and do nothing. This is also true for
-v4l2_ctrl_handler_init if it cannot allocate the internal data structure.
-
-This makes it easy to init the handler and just add all controls and only check
-the error code at the end. Saves a lot of repetitive error checking.
-
-It is recommended to add controls in ascending control ID order: it will be
-a bit faster that way.
-
-3) Optionally force initial control setup:
-
-	v4l2_ctrl_handler_setup(&foo->ctrl_handler);
-
-This will call s_ctrl for all controls unconditionally. Effectively this
-initializes the hardware to the default control values. It is recommended
-that you do this as this ensures that both the internal data structures and
-the hardware are in sync.
-
-4) Finally: implement the v4l2_ctrl_ops
-
-	static const struct v4l2_ctrl_ops foo_ctrl_ops = {
-		.s_ctrl = foo_s_ctrl,
-	};
-
-Usually all you need is s_ctrl:
-
-	static int foo_s_ctrl(struct v4l2_ctrl *ctrl)
-	{
-		struct foo *state = container_of(ctrl->handler, struct foo, ctrl_handler);
-
-		switch (ctrl->id) {
-		case V4L2_CID_BRIGHTNESS:
-			write_reg(0x123, ctrl->val);
-			break;
-		case V4L2_CID_CONTRAST:
-			write_reg(0x456, ctrl->val);
-			break;
-		}
-		return 0;
-	}
-
-The control ops are called with the v4l2_ctrl pointer as argument.
-The new control value has already been validated, so all you need to do is
-to actually update the hardware registers.
-
-You're done! And this is sufficient for most of the drivers we have. No need
-to do any validation of control values, or implement QUERYCTRL, QUERY_EXT_CTRL
-and QUERYMENU. And G/S_CTRL as well as G/TRY/S_EXT_CTRLS are automatically supported.
-
-
-==============================================================================
-
-The remainder of this document deals with more advanced topics and scenarios.
-In practice the basic usage as described above is sufficient for most drivers.
-
-===============================================================================
-
-
-Inheriting Controls
-===================
-
-When a sub-device is registered with a V4L2 driver by calling
-v4l2_device_register_subdev() and the ctrl_handler fields of both v4l2_subdev
-and v4l2_device are set, then the controls of the subdev will become
-automatically available in the V4L2 driver as well. If the subdev driver
-contains controls that already exist in the V4L2 driver, then those will be
-skipped (so a V4L2 driver can always override a subdev control).
-
-What happens here is that v4l2_device_register_subdev() calls
-v4l2_ctrl_add_handler() adding the controls of the subdev to the controls
-of v4l2_device.
-
-
-Accessing Control Values
-========================
-
-The following union is used inside the control framework to access control
-values:
-
-union v4l2_ctrl_ptr {
-	s32 *p_s32;
-	s64 *p_s64;
-	char *p_char;
-	void *p;
-};
-
-The v4l2_ctrl struct contains these fields that can be used to access both
-current and new values:
-
-	s32 val;
-	struct {
-		s32 val;
-	} cur;
-
-
-	union v4l2_ctrl_ptr p_new;
-	union v4l2_ctrl_ptr p_cur;
-
-If the control has a simple s32 type type, then:
-
-	&ctrl->val == ctrl->p_new.p_s32
-	&ctrl->cur.val == ctrl->p_cur.p_s32
-
-For all other types use ctrl->p_cur.p<something>. Basically the val
-and cur.val fields can be considered an alias since these are used so often.
-
-Within the control ops you can freely use these. The val and cur.val speak for
-themselves. The p_char pointers point to character buffers of length
-ctrl->maximum + 1, and are always 0-terminated.
-
-Unless the control is marked volatile the p_cur field points to the the
-current cached control value. When you create a new control this value is made
-identical to the default value. After calling v4l2_ctrl_handler_setup() this
-value is passed to the hardware. It is generally a good idea to call this
-function.
-
-Whenever a new value is set that new value is automatically cached. This means
-that most drivers do not need to implement the g_volatile_ctrl() op. The
-exception is for controls that return a volatile register such as a signal
-strength read-out that changes continuously. In that case you will need to
-implement g_volatile_ctrl like this:
-
-	static int foo_g_volatile_ctrl(struct v4l2_ctrl *ctrl)
-	{
-		switch (ctrl->id) {
-		case V4L2_CID_BRIGHTNESS:
-			ctrl->val = read_reg(0x123);
-			break;
-		}
-	}
-
-Note that you use the 'new value' union as well in g_volatile_ctrl. In general
-controls that need to implement g_volatile_ctrl are read-only controls. If they
-are not, a V4L2_EVENT_CTRL_CH_VALUE will not be generated when the control
-changes.
-
-To mark a control as volatile you have to set V4L2_CTRL_FLAG_VOLATILE:
-
-	ctrl = v4l2_ctrl_new_std(&sd->ctrl_handler, ...);
-	if (ctrl)
-		ctrl->flags |= V4L2_CTRL_FLAG_VOLATILE;
-
-For try/s_ctrl the new values (i.e. as passed by the user) are filled in and
-you can modify them in try_ctrl or set them in s_ctrl. The 'cur' union
-contains the current value, which you can use (but not change!) as well.
-
-If s_ctrl returns 0 (OK), then the control framework will copy the new final
-values to the 'cur' union.
-
-While in g_volatile/s/try_ctrl you can access the value of all controls owned
-by the same handler since the handler's lock is held. If you need to access
-the value of controls owned by other handlers, then you have to be very careful
-not to introduce deadlocks.
-
-Outside of the control ops you have to go through to helper functions to get
-or set a single control value safely in your driver:
-
-	s32 v4l2_ctrl_g_ctrl(struct v4l2_ctrl *ctrl);
-	int v4l2_ctrl_s_ctrl(struct v4l2_ctrl *ctrl, s32 val);
-
-These functions go through the control framework just as VIDIOC_G/S_CTRL ioctls
-do. Don't use these inside the control ops g_volatile/s/try_ctrl, though, that
-will result in a deadlock since these helpers lock the handler as well.
-
-You can also take the handler lock yourself:
-
-	mutex_lock(&state->ctrl_handler.lock);
-	pr_info("String value is '%s'\n", ctrl1->p_cur.p_char);
-	pr_info("Integer value is '%s'\n", ctrl2->cur.val);
-	mutex_unlock(&state->ctrl_handler.lock);
-
-
-Menu Controls
-=============
-
-The v4l2_ctrl struct contains this union:
-
-	union {
-		u32 step;
-		u32 menu_skip_mask;
-	};
-
-For menu controls menu_skip_mask is used. What it does is that it allows you
-to easily exclude certain menu items. This is used in the VIDIOC_QUERYMENU
-implementation where you can return -EINVAL if a certain menu item is not
-present. Note that VIDIOC_QUERYCTRL always returns a step value of 1 for
-menu controls.
-
-A good example is the MPEG Audio Layer II Bitrate menu control where the
-menu is a list of standardized possible bitrates. But in practice hardware
-implementations will only support a subset of those. By setting the skip
-mask you can tell the framework which menu items should be skipped. Setting
-it to 0 means that all menu items are supported.
-
-You set this mask either through the v4l2_ctrl_config struct for a custom
-control, or by calling v4l2_ctrl_new_std_menu().
-
-
-Custom Controls
-===============
-
-Driver specific controls can be created using v4l2_ctrl_new_custom():
-
-	static const struct v4l2_ctrl_config ctrl_filter = {
-		.ops = &ctrl_custom_ops,
-		.id = V4L2_CID_MPEG_CX2341X_VIDEO_SPATIAL_FILTER,
-		.name = "Spatial Filter",
-		.type = V4L2_CTRL_TYPE_INTEGER,
-		.flags = V4L2_CTRL_FLAG_SLIDER,
-		.max = 15,
-		.step = 1,
-	};
-
-	ctrl = v4l2_ctrl_new_custom(&foo->ctrl_handler, &ctrl_filter, NULL);
-
-The last argument is the priv pointer which can be set to driver-specific
-private data.
-
-The v4l2_ctrl_config struct also has a field to set the is_private flag.
-
-If the name field is not set, then the framework will assume this is a standard
-control and will fill in the name, type and flags fields accordingly.
-
-
-Active and Grabbed Controls
-===========================
-
-If you get more complex relationships between controls, then you may have to
-activate and deactivate controls. For example, if the Chroma AGC control is
-on, then the Chroma Gain control is inactive. That is, you may set it, but
-the value will not be used by the hardware as long as the automatic gain
-control is on. Typically user interfaces can disable such input fields.
-
-You can set the 'active' status using v4l2_ctrl_activate(). By default all
-controls are active. Note that the framework does not check for this flag.
-It is meant purely for GUIs. The function is typically called from within
-s_ctrl.
-
-The other flag is the 'grabbed' flag. A grabbed control means that you cannot
-change it because it is in use by some resource. Typical examples are MPEG
-bitrate controls that cannot be changed while capturing is in progress.
-
-If a control is set to 'grabbed' using v4l2_ctrl_grab(), then the framework
-will return -EBUSY if an attempt is made to set this control. The
-v4l2_ctrl_grab() function is typically called from the driver when it
-starts or stops streaming.
-
-
-Control Clusters
-================
-
-By default all controls are independent from the others. But in more
-complex scenarios you can get dependencies from one control to another.
-In that case you need to 'cluster' them:
-
-	struct foo {
-		struct v4l2_ctrl_handler ctrl_handler;
-#define AUDIO_CL_VOLUME (0)
-#define AUDIO_CL_MUTE   (1)
-		struct v4l2_ctrl *audio_cluster[2];
-		...
-	};
-
-	state->audio_cluster[AUDIO_CL_VOLUME] =
-		v4l2_ctrl_new_std(&state->ctrl_handler, ...);
-	state->audio_cluster[AUDIO_CL_MUTE] =
-		v4l2_ctrl_new_std(&state->ctrl_handler, ...);
-	v4l2_ctrl_cluster(ARRAY_SIZE(state->audio_cluster), state->audio_cluster);
-
-From now on whenever one or more of the controls belonging to the same
-cluster is set (or 'gotten', or 'tried'), only the control ops of the first
-control ('volume' in this example) is called. You effectively create a new
-composite control. Similar to how a 'struct' works in C.
-
-So when s_ctrl is called with V4L2_CID_AUDIO_VOLUME as argument, you should set
-all two controls belonging to the audio_cluster:
-
-	static int foo_s_ctrl(struct v4l2_ctrl *ctrl)
-	{
-		struct foo *state = container_of(ctrl->handler, struct foo, ctrl_handler);
-
-		switch (ctrl->id) {
-		case V4L2_CID_AUDIO_VOLUME: {
-			struct v4l2_ctrl *mute = ctrl->cluster[AUDIO_CL_MUTE];
-
-			write_reg(0x123, mute->val ? 0 : ctrl->val);
-			break;
-		}
-		case V4L2_CID_CONTRAST:
-			write_reg(0x456, ctrl->val);
-			break;
-		}
-		return 0;
-	}
-
-In the example above the following are equivalent for the VOLUME case:
-
-	ctrl == ctrl->cluster[AUDIO_CL_VOLUME] == state->audio_cluster[AUDIO_CL_VOLUME]
-	ctrl->cluster[AUDIO_CL_MUTE] == state->audio_cluster[AUDIO_CL_MUTE]
-
-In practice using cluster arrays like this becomes very tiresome. So instead
-the following equivalent method is used:
-
-	struct {
-		/* audio cluster */
-		struct v4l2_ctrl *volume;
-		struct v4l2_ctrl *mute;
-	};
-
-The anonymous struct is used to clearly 'cluster' these two control pointers,
-but it serves no other purpose. The effect is the same as creating an
-array with two control pointers. So you can just do:
-
-	state->volume = v4l2_ctrl_new_std(&state->ctrl_handler, ...);
-	state->mute = v4l2_ctrl_new_std(&state->ctrl_handler, ...);
-	v4l2_ctrl_cluster(2, &state->volume);
-
-And in foo_s_ctrl you can use these pointers directly: state->mute->val.
-
-Note that controls in a cluster may be NULL. For example, if for some
-reason mute was never added (because the hardware doesn't support that
-particular feature), then mute will be NULL. So in that case we have a
-cluster of 2 controls, of which only 1 is actually instantiated. The
-only restriction is that the first control of the cluster must always be
-present, since that is the 'master' control of the cluster. The master
-control is the one that identifies the cluster and that provides the
-pointer to the v4l2_ctrl_ops struct that is used for that cluster.
-
-Obviously, all controls in the cluster array must be initialized to either
-a valid control or to NULL.
-
-In rare cases you might want to know which controls of a cluster actually
-were set explicitly by the user. For this you can check the 'is_new' flag of
-each control. For example, in the case of a volume/mute cluster the 'is_new'
-flag of the mute control would be set if the user called VIDIOC_S_CTRL for
-mute only. If the user would call VIDIOC_S_EXT_CTRLS for both mute and volume
-controls, then the 'is_new' flag would be 1 for both controls.
-
-The 'is_new' flag is always 1 when called from v4l2_ctrl_handler_setup().
-
-
-Handling autogain/gain-type Controls with Auto Clusters
-=======================================================
-
-A common type of control cluster is one that handles 'auto-foo/foo'-type
-controls. Typical examples are autogain/gain, autoexposure/exposure,
-autowhitebalance/red balance/blue balance. In all cases you have one control
-that determines whether another control is handled automatically by the hardware,
-or whether it is under manual control from the user.
-
-If the cluster is in automatic mode, then the manual controls should be
-marked inactive and volatile. When the volatile controls are read the
-g_volatile_ctrl operation should return the value that the hardware's automatic
-mode set up automatically.
-
-If the cluster is put in manual mode, then the manual controls should become
-active again and the volatile flag is cleared (so g_volatile_ctrl is no longer
-called while in manual mode). In addition just before switching to manual mode
-the current values as determined by the auto mode are copied as the new manual
-values.
-
-Finally the V4L2_CTRL_FLAG_UPDATE should be set for the auto control since
-changing that control affects the control flags of the manual controls.
-
-In order to simplify this a special variation of v4l2_ctrl_cluster was
-introduced:
-
-void v4l2_ctrl_auto_cluster(unsigned ncontrols, struct v4l2_ctrl **controls,
-			u8 manual_val, bool set_volatile);
-
-The first two arguments are identical to v4l2_ctrl_cluster. The third argument
-tells the framework which value switches the cluster into manual mode. The
-last argument will optionally set V4L2_CTRL_FLAG_VOLATILE for the non-auto controls.
-If it is false, then the manual controls are never volatile. You would typically
-use that if the hardware does not give you the option to read back to values as
-determined by the auto mode (e.g. if autogain is on, the hardware doesn't allow
-you to obtain the current gain value).
-
-The first control of the cluster is assumed to be the 'auto' control.
-
-Using this function will ensure that you don't need to handle all the complex
-flag and volatile handling.
-
-
-VIDIOC_LOG_STATUS Support
-=========================
-
-This ioctl allow you to dump the current status of a driver to the kernel log.
-The v4l2_ctrl_handler_log_status(ctrl_handler, prefix) can be used to dump the
-value of the controls owned by the given handler to the log. You can supply a
-prefix as well. If the prefix didn't end with a space, then ': ' will be added
-for you.
-
-
-Different Handlers for Different Video Nodes
-============================================
-
-Usually the V4L2 driver has just one control handler that is global for
-all video nodes. But you can also specify different control handlers for
-different video nodes. You can do that by manually setting the ctrl_handler
-field of struct video_device.
-
-That is no problem if there are no subdevs involved but if there are, then
-you need to block the automatic merging of subdev controls to the global
-control handler. You do that by simply setting the ctrl_handler field in
-struct v4l2_device to NULL. Now v4l2_device_register_subdev() will no longer
-merge subdev controls.
-
-After each subdev was added, you will then have to call v4l2_ctrl_add_handler
-manually to add the subdev's control handler (sd->ctrl_handler) to the desired
-control handler. This control handler may be specific to the video_device or
-for a subset of video_device's. For example: the radio device nodes only have
-audio controls, while the video and vbi device nodes share the same control
-handler for the audio and video controls.
-
-If you want to have one handler (e.g. for a radio device node) have a subset
-of another handler (e.g. for a video device node), then you should first add
-the controls to the first handler, add the other controls to the second
-handler and finally add the first handler to the second. For example:
-
-	v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_VOLUME, ...);
-	v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_MUTE, ...);
-	v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_BRIGHTNESS, ...);
-	v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_CONTRAST, ...);
-	v4l2_ctrl_add_handler(&video_ctrl_handler, &radio_ctrl_handler, NULL);
-
-The last argument to v4l2_ctrl_add_handler() is a filter function that allows
-you to filter which controls will be added. Set it to NULL if you want to add
-all controls.
-
-Or you can add specific controls to a handler:
-
-	volume = v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_AUDIO_VOLUME, ...);
-	v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_BRIGHTNESS, ...);
-	v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_CONTRAST, ...);
-
-What you should not do is make two identical controls for two handlers.
-For example:
-
-	v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_MUTE, ...);
-	v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_AUDIO_MUTE, ...);
-
-This would be bad since muting the radio would not change the video mute
-control. The rule is to have one control for each hardware 'knob' that you
-can twiddle.
-
-
-Finding Controls
-================
-
-Normally you have created the controls yourself and you can store the struct
-v4l2_ctrl pointer into your own struct.
-
-But sometimes you need to find a control from another handler that you do
-not own. For example, if you have to find a volume control from a subdev.
-
-You can do that by calling v4l2_ctrl_find:
-
-	struct v4l2_ctrl *volume;
-
-	volume = v4l2_ctrl_find(sd->ctrl_handler, V4L2_CID_AUDIO_VOLUME);
-
-Since v4l2_ctrl_find will lock the handler you have to be careful where you
-use it. For example, this is not a good idea:
-
-	struct v4l2_ctrl_handler ctrl_handler;
-
-	v4l2_ctrl_new_std(&ctrl_handler, &video_ops, V4L2_CID_BRIGHTNESS, ...);
-	v4l2_ctrl_new_std(&ctrl_handler, &video_ops, V4L2_CID_CONTRAST, ...);
-
-...and in video_ops.s_ctrl:
-
-	case V4L2_CID_BRIGHTNESS:
-		contrast = v4l2_find_ctrl(&ctrl_handler, V4L2_CID_CONTRAST);
-		...
-
-When s_ctrl is called by the framework the ctrl_handler.lock is already taken, so
-attempting to find another control from the same handler will deadlock.
-
-It is recommended not to use this function from inside the control ops.
-
-
-Inheriting Controls
-===================
-
-When one control handler is added to another using v4l2_ctrl_add_handler, then
-by default all controls from one are merged to the other. But a subdev might
-have low-level controls that make sense for some advanced embedded system, but
-not when it is used in consumer-level hardware. In that case you want to keep
-those low-level controls local to the subdev. You can do this by simply
-setting the 'is_private' flag of the control to 1:
-
-	static const struct v4l2_ctrl_config ctrl_private = {
-		.ops = &ctrl_custom_ops,
-		.id = V4L2_CID_...,
-		.name = "Some Private Control",
-		.type = V4L2_CTRL_TYPE_INTEGER,
-		.max = 15,
-		.step = 1,
-		.is_private = 1,
-	};
-
-	ctrl = v4l2_ctrl_new_custom(&foo->ctrl_handler, &ctrl_private, NULL);
-
-These controls will now be skipped when v4l2_ctrl_add_handler is called.
-
-
-V4L2_CTRL_TYPE_CTRL_CLASS Controls
-==================================
-
-Controls of this type can be used by GUIs to get the name of the control class.
-A fully featured GUI can make a dialog with multiple tabs with each tab
-containing the controls belonging to a particular control class. The name of
-each tab can be found by querying a special control with ID <control class | 1>.
-
-Drivers do not have to care about this. The framework will automatically add
-a control of this type whenever the first control belonging to a new control
-class is added.
-
-
-Adding Notify Callbacks
-=======================
-
-Sometimes the platform or bridge driver needs to be notified when a control
-from a sub-device driver changes. You can set a notify callback by calling
-this function:
-
-void v4l2_ctrl_notify(struct v4l2_ctrl *ctrl,
-	void (*notify)(struct v4l2_ctrl *ctrl, void *priv), void *priv);
-
-Whenever the give control changes value the notify callback will be called
-with a pointer to the control and the priv pointer that was passed with
-v4l2_ctrl_notify. Note that the control's handler lock is held when the
-notify function is called.
-
-There can be only one notify function per control handler. Any attempt
-to set another notify function will cause a WARN_ON.

-Overview of the V4L2 driver framework
-=====================================
-
-This text documents the various structures provided by the V4L2 framework and
-their relationships.
-
-
-Introduction
-------------
-
-The V4L2 drivers tend to be very complex due to the complexity of the
-hardware: most devices have multiple ICs, export multiple device nodes in
-/dev, and create also non-V4L2 devices such as DVB, ALSA, FB, I2C and input
-(IR) devices.
-
-Especially the fact that V4L2 drivers have to setup supporting ICs to
-do audio/video muxing/encoding/decoding makes it more complex than most.
-Usually these ICs are connected to the main bridge driver through one or
-more I2C busses, but other busses can also be used. Such devices are
-called 'sub-devices'.
-
-For a long time the framework was limited to the video_device struct for
-creating V4L device nodes and video_buf for handling the video buffers
-(note that this document does not discuss the video_buf framework).
-
-This meant that all drivers had to do the setup of device instances and
-connecting to sub-devices themselves. Some of this is quite complicated
-to do right and many drivers never did do it correctly.
-
-There is also a lot of common code that could never be refactored due to
-the lack of a framework.
-
-So this framework sets up the basic building blocks that all drivers
-need and this same framework should make it much easier to refactor
-common code into utility functions shared by all drivers.
-
-A good example to look at as a reference is the v4l2-pci-skeleton.c
-source that is available in samples/v4l/. It is a skeleton driver for
-a PCI capture card, and demonstrates how to use the V4L2 driver
-framework. It can be used as a template for real PCI video capture driver.
-
-Structure of a driver
----------------------
-
-All drivers have the following structure:
-
-1) A struct for each device instance containing the device state.
-
-2) A way of initializing and commanding sub-devices (if any).
-
-3) Creating V4L2 device nodes (/dev/videoX, /dev/vbiX and /dev/radioX)
-   and keeping track of device-node specific data.
-
-4) Filehandle-specific structs containing per-filehandle data;
-
-5) video buffer handling.
-
-This is a rough schematic of how it all relates:
-
-    device instances
-      |
-      +-sub-device instances
-      |
-      \-V4L2 device nodes
-	  |
-	  \-filehandle instances
-
-
-Structure of the framework
---------------------------
-
-The framework closely resembles the driver structure: it has a v4l2_device
-struct for the device instance data, a v4l2_subdev struct to refer to
-sub-device instances, the video_device struct stores V4L2 device node data
-and the v4l2_fh struct keeps track of filehandle instances.
-
-The V4L2 framework also optionally integrates with the media framework. If a
-driver sets the struct v4l2_device mdev field, sub-devices and video nodes
-will automatically appear in the media framework as entities.
-
-
-struct v4l2_device
-------------------
-
-Each device instance is represented by a struct v4l2_device (v4l2-device.h).
-Very simple devices can just allocate this struct, but most of the time you
-would embed this struct inside a larger struct.
-
-You must register the device instance:
-
-	v4l2_device_register(struct device *dev, struct v4l2_device *v4l2_dev);
-
-Registration will initialize the v4l2_device struct. If the dev->driver_data
-field is NULL, it will be linked to v4l2_dev.
-
-Drivers that want integration with the media device framework need to set
-dev->driver_data manually to point to the driver-specific device structure
-that embed the struct v4l2_device instance. This is achieved by a
-dev_set_drvdata() call before registering the V4L2 device instance. They must
-also set the struct v4l2_device mdev field to point to a properly initialized
-and registered media_device instance.
-
-If v4l2_dev->name is empty then it will be set to a value derived from dev
-(driver name followed by the bus_id, to be precise). If you set it up before
-calling v4l2_device_register then it will be untouched. If dev is NULL, then
-you *must* setup v4l2_dev->name before calling v4l2_device_register.
-
-You can use v4l2_device_set_name() to set the name based on a driver name and
-a driver-global atomic_t instance. This will generate names like ivtv0, ivtv1,
-etc. If the name ends with a digit, then it will insert a dash: cx18-0,
-cx18-1, etc. This function returns the instance number.
-
-The first 'dev' argument is normally the struct device pointer of a pci_dev,
-usb_interface or platform_device. It is rare for dev to be NULL, but it happens
-with ISA devices or when one device creates multiple PCI devices, thus making
-it impossible to associate v4l2_dev with a particular parent.
-
-You can also supply a notify() callback that can be called by sub-devices to
-notify you of events. Whether you need to set this depends on the sub-device.
-Any notifications a sub-device supports must be defined in a header in
-include/media/<subdevice>.h.
-
-You unregister with:
-
-	v4l2_device_unregister(struct v4l2_device *v4l2_dev);
-
-If the dev->driver_data field points to v4l2_dev, it will be reset to NULL.
-Unregistering will also automatically unregister all subdevs from the device.
-
-If you have a hotpluggable device (e.g. a USB device), then when a disconnect
-happens the parent device becomes invalid. Since v4l2_device has a pointer to
-that parent device it has to be cleared as well to mark that the parent is
-gone. To do this call:
-
-	v4l2_device_disconnect(struct v4l2_device *v4l2_dev);
-
-This does *not* unregister the subdevs, so you still need to call the
-v4l2_device_unregister() function for that. If your driver is not hotpluggable,
-then there is no need to call v4l2_device_disconnect().
-
-Sometimes you need to iterate over all devices registered by a specific
-driver. This is usually the case if multiple device drivers use the same
-hardware. E.g. the ivtvfb driver is a framebuffer driver that uses the ivtv
-hardware. The same is true for alsa drivers for example.
-
-You can iterate over all registered devices as follows:
-
-static int callback(struct device *dev, void *p)
-{
-	struct v4l2_device *v4l2_dev = dev_get_drvdata(dev);
-
-	/* test if this device was inited */
-	if (v4l2_dev == NULL)
-		return 0;
-	...
-	return 0;
-}
-
-int iterate(void *p)
-{
-	struct device_driver *drv;
-	int err;
-
-	/* Find driver 'ivtv' on the PCI bus.
-	   pci_bus_type is a global. For USB busses use usb_bus_type. */
-	drv = driver_find("ivtv", &pci_bus_type);
-	/* iterate over all ivtv device instances */
-	err = driver_for_each_device(drv, NULL, p, callback);
-	put_driver(drv);
-	return err;
-}
-
-Sometimes you need to keep a running counter of the device instance. This is
-commonly used to map a device instance to an index of a module option array.
-
-The recommended approach is as follows:
-
-static atomic_t drv_instance = ATOMIC_INIT(0);
-
-static int drv_probe(struct pci_dev *pdev, const struct pci_device_id *pci_id)
-{
-	...
-	state->instance = atomic_inc_return(&drv_instance) - 1;
-}
-
-If you have multiple device nodes then it can be difficult to know when it is
-safe to unregister v4l2_device for hotpluggable devices. For this purpose
-v4l2_device has refcounting support. The refcount is increased whenever
-video_register_device is called and it is decreased whenever that device node
-is released. When the refcount reaches zero, then the v4l2_device release()
-callback is called. You can do your final cleanup there.
-
-If other device nodes (e.g. ALSA) are created, then you can increase and
-decrease the refcount manually as well by calling:
-
-void v4l2_device_get(struct v4l2_device *v4l2_dev);
-
-or:
-
-int v4l2_device_put(struct v4l2_device *v4l2_dev);
-
-Since the initial refcount is 1 you also need to call v4l2_device_put in the
-disconnect() callback (for USB devices) or in the remove() callback (for e.g.
-PCI devices), otherwise the refcount will never reach 0.
-
-struct v4l2_subdev
-------------------
-
-Many drivers need to communicate with sub-devices. These devices can do all
-sort of tasks, but most commonly they handle audio and/or video muxing,
-encoding or decoding. For webcams common sub-devices are sensors and camera
-controllers.
-
-Usually these are I2C devices, but not necessarily. In order to provide the
-driver with a consistent interface to these sub-devices the v4l2_subdev struct
-(v4l2-subdev.h) was created.
-
-Each sub-device driver must have a v4l2_subdev struct. This struct can be
-stand-alone for simple sub-devices or it might be embedded in a larger struct
-if more state information needs to be stored. Usually there is a low-level
-device struct (e.g. i2c_client) that contains the device data as setup
-by the kernel. It is recommended to store that pointer in the private
-data of v4l2_subdev using v4l2_set_subdevdata(). That makes it easy to go
-from a v4l2_subdev to the actual low-level bus-specific device data.
-
-You also need a way to go from the low-level struct to v4l2_subdev. For the
-common i2c_client struct the i2c_set_clientdata() call is used to store a
-v4l2_subdev pointer, for other busses you may have to use other methods.
-
-Bridges might also need to store per-subdev private data, such as a pointer to
-bridge-specific per-subdev private data. The v4l2_subdev structure provides
-host private data for that purpose that can be accessed with
-v4l2_get_subdev_hostdata() and v4l2_set_subdev_hostdata().
-
-From the bridge driver perspective you load the sub-device module and somehow
-obtain the v4l2_subdev pointer. For i2c devices this is easy: you call
-i2c_get_clientdata(). For other busses something similar needs to be done.
-Helper functions exists for sub-devices on an I2C bus that do most of this
-tricky work for you.
-
-Each v4l2_subdev contains function pointers that sub-device drivers can
-implement (or leave NULL if it is not applicable). Since sub-devices can do
-so many different things and you do not want to end up with a huge ops struct
-of which only a handful of ops are commonly implemented, the function pointers
-are sorted according to category and each category has its own ops struct.
-
-The top-level ops struct contains pointers to the category ops structs, which
-may be NULL if the subdev driver does not support anything from that category.
-
-It looks like this:
-
-struct v4l2_subdev_core_ops {
-	int (*log_status)(struct v4l2_subdev *sd);
-	int (*init)(struct v4l2_subdev *sd, u32 val);
-	...
-};
-
-struct v4l2_subdev_tuner_ops {
-	...
-};
-
-struct v4l2_subdev_audio_ops {
-	...
-};
-
-struct v4l2_subdev_video_ops {
-	...
-};
-
-struct v4l2_subdev_pad_ops {
-	...
-};
-
-struct v4l2_subdev_ops {
-	const struct v4l2_subdev_core_ops  *core;
-	const struct v4l2_subdev_tuner_ops *tuner;
-	const struct v4l2_subdev_audio_ops *audio;
-	const struct v4l2_subdev_video_ops *video;
-	const struct v4l2_subdev_pad_ops *video;
-};
-
-The core ops are common to all subdevs, the other categories are implemented
-depending on the sub-device. E.g. a video device is unlikely to support the
-audio ops and vice versa.
-
-This setup limits the number of function pointers while still making it easy
-to add new ops and categories.
-
-A sub-device driver initializes the v4l2_subdev struct using:
-
-	v4l2_subdev_init(sd, &ops);
-
-Afterwards you need to initialize subdev->name with a unique name and set the
-module owner. This is done for you if you use the i2c helper functions.
-
-If integration with the media framework is needed, you must initialize the
-media_entity struct embedded in the v4l2_subdev struct (entity field) by
-calling media_entity_pads_init(), if the entity has pads:
-
-	struct media_pad *pads = &my_sd->pads;
-	int err;
-
-	err = media_entity_pads_init(&sd->entity, npads, pads);
-
-The pads array must have been previously initialized. There is no need to
-manually set the struct media_entity function and name fields, but the
-revision field must be initialized if needed.
-
-A reference to the entity will be automatically acquired/released when the
-subdev device node (if any) is opened/closed.
-
-Don't forget to cleanup the media entity before the sub-device is destroyed:
-
-	media_entity_cleanup(&sd->entity);
-
-If the subdev driver intends to process video and integrate with the media
-framework, it must implement format related functionality using
-v4l2_subdev_pad_ops instead of v4l2_subdev_video_ops.
-
-In that case, the subdev driver may set the link_validate field to provide
-its own link validation function. The link validation function is called for
-every link in the pipeline where both of the ends of the links are V4L2
-sub-devices. The driver is still responsible for validating the correctness
-of the format configuration between sub-devices and video nodes.
-
-If link_validate op is not set, the default function
-v4l2_subdev_link_validate_default() is used instead. This function ensures
-that width, height and the media bus pixel code are equal on both source and
-sink of the link. Subdev drivers are also free to use this function to
-perform the checks mentioned above in addition to their own checks.
-
-There are currently two ways to register subdevices with the V4L2 core. The
-first (traditional) possibility is to have subdevices registered by bridge
-drivers. This can be done when the bridge driver has the complete information
-about subdevices connected to it and knows exactly when to register them. This
-is typically the case for internal subdevices, like video data processing units
-within SoCs or complex PCI(e) boards, camera sensors in USB cameras or connected
-to SoCs, which pass information about them to bridge drivers, usually in their
-platform data.
-
-There are however also situations where subdevices have to be registered
-asynchronously to bridge devices. An example of such a configuration is a Device
-Tree based system where information about subdevices is made available to the
-system independently from the bridge devices, e.g. when subdevices are defined
-in DT as I2C device nodes. The API used in this second case is described further
-below.
-
-Using one or the other registration method only affects the probing process, the
-run-time bridge-subdevice interaction is in both cases the same.
-
-In the synchronous case a device (bridge) driver needs to register the
-v4l2_subdev with the v4l2_device:
-
-	int err = v4l2_device_register_subdev(v4l2_dev, sd);
-
-This can fail if the subdev module disappeared before it could be registered.
-After this function was called successfully the subdev->dev field points to
-the v4l2_device.
-
-If the v4l2_device parent device has a non-NULL mdev field, the sub-device
-entity will be automatically registered with the media device.
-
-You can unregister a sub-device using:
-
-	v4l2_device_unregister_subdev(sd);
-
-Afterwards the subdev module can be unloaded and sd->dev == NULL.
-
-You can call an ops function either directly:
-
-	err = sd->ops->core->g_std(sd, &norm);
-
-but it is better and easier to use this macro:
-
-	err = v4l2_subdev_call(sd, core, g_std, &norm);
-
-The macro will to the right NULL pointer checks and returns -ENODEV if subdev
-is NULL, -ENOIOCTLCMD if either subdev->core or subdev->core->g_std is
-NULL, or the actual result of the subdev->ops->core->g_std ops.
-
-It is also possible to call all or a subset of the sub-devices:
-
-	v4l2_device_call_all(v4l2_dev, 0, core, g_std, &norm);
-
-Any subdev that does not support this ops is skipped and error results are
-ignored. If you want to check for errors use this:
-
-	err = v4l2_device_call_until_err(v4l2_dev, 0, core, g_std, &norm);
-
-Any error except -ENOIOCTLCMD will exit the loop with that error. If no
-errors (except -ENOIOCTLCMD) occurred, then 0 is returned.
-
-The second argument to both calls is a group ID. If 0, then all subdevs are
-called. If non-zero, then only those whose group ID match that value will
-be called. Before a bridge driver registers a subdev it can set sd->grp_id
-to whatever value it wants (it's 0 by default). This value is owned by the
-bridge driver and the sub-device driver will never modify or use it.
-
-The group ID gives the bridge driver more control how callbacks are called.
-For example, there may be multiple audio chips on a board, each capable of
-changing the volume. But usually only one will actually be used when the
-user want to change the volume. You can set the group ID for that subdev to
-e.g. AUDIO_CONTROLLER and specify that as the group ID value when calling
-v4l2_device_call_all(). That ensures that it will only go to the subdev
-that needs it.
-
-If the sub-device needs to notify its v4l2_device parent of an event, then
-it can call v4l2_subdev_notify(sd, notification, arg). This macro checks
-whether there is a notify() callback defined and returns -ENODEV if not.
-Otherwise the result of the notify() call is returned.
-
-The advantage of using v4l2_subdev is that it is a generic struct and does
-not contain any knowledge about the underlying hardware. So a driver might
-contain several subdevs that use an I2C bus, but also a subdev that is
-controlled through GPIO pins. This distinction is only relevant when setting
-up the device, but once the subdev is registered it is completely transparent.
-
-
-In the asynchronous case subdevice probing can be invoked independently of the
-bridge driver availability. The subdevice driver then has to verify whether all
-the requirements for a successful probing are satisfied. This can include a
-check for a master clock availability. If any of the conditions aren't satisfied
-the driver might decide to return -EPROBE_DEFER to request further reprobing
-attempts. Once all conditions are met the subdevice shall be registered using
-the v4l2_async_register_subdev() function. Unregistration is performed using
-the v4l2_async_unregister_subdev() call. Subdevices registered this way are
-stored in a global list of subdevices, ready to be picked up by bridge drivers.
-
-Bridge drivers in turn have to register a notifier object with an array of
-subdevice descriptors that the bridge device needs for its operation. This is
-performed using the v4l2_async_notifier_register() call. To unregister the
-notifier the driver has to call v4l2_async_notifier_unregister(). The former of
-the two functions takes two arguments: a pointer to struct v4l2_device and a
-pointer to struct v4l2_async_notifier. The latter contains a pointer to an array
-of pointers to subdevice descriptors of type struct v4l2_async_subdev type. The
-V4L2 core will then use these descriptors to match asynchronously registered
-subdevices to them. If a match is detected the .bound() notifier callback is
-called. After all subdevices have been located the .complete() callback is
-called. When a subdevice is removed from the system the .unbind() method is
-called. All three callbacks are optional.
-
-
-V4L2 sub-device userspace API
------------------------------
-
-Beside exposing a kernel API through the v4l2_subdev_ops structure, V4L2
-sub-devices can also be controlled directly by userspace applications.
-
-Device nodes named v4l-subdevX can be created in /dev to access sub-devices
-directly. If a sub-device supports direct userspace configuration it must set
-the V4L2_SUBDEV_FL_HAS_DEVNODE flag before being registered.
-
-After registering sub-devices, the v4l2_device driver can create device nodes
-for all registered sub-devices marked with V4L2_SUBDEV_FL_HAS_DEVNODE by calling
-v4l2_device_register_subdev_nodes(). Those device nodes will be automatically
-removed when sub-devices are unregistered.
-
-The device node handles a subset of the V4L2 API.
-
-VIDIOC_QUERYCTRL
-VIDIOC_QUERYMENU
-VIDIOC_G_CTRL
-VIDIOC_S_CTRL
-VIDIOC_G_EXT_CTRLS
-VIDIOC_S_EXT_CTRLS
-VIDIOC_TRY_EXT_CTRLS
-
-	The controls ioctls are identical to the ones defined in V4L2. They
-	behave identically, with the only exception that they deal only with
-	controls implemented in the sub-device. Depending on the driver, those
-	controls can be also be accessed through one (or several) V4L2 device
-	nodes.
-
-VIDIOC_DQEVENT
-VIDIOC_SUBSCRIBE_EVENT
-VIDIOC_UNSUBSCRIBE_EVENT
-
-	The events ioctls are identical to the ones defined in V4L2. They
-	behave identically, with the only exception that they deal only with
-	events generated by the sub-device. Depending on the driver, those
-	events can also be reported by one (or several) V4L2 device nodes.
-
-	Sub-device drivers that want to use events need to set the
-	V4L2_SUBDEV_USES_EVENTS v4l2_subdev::flags and initialize
-	v4l2_subdev::nevents to events queue depth before registering the
-	sub-device. After registration events can be queued as usual on the
-	v4l2_subdev::devnode device node.
-
-	To properly support events, the poll() file operation is also
-	implemented.
-
-Private ioctls
-
-	All ioctls not in the above list are passed directly to the sub-device
-	driver through the core::ioctl operation.
-
-
-I2C sub-device drivers
-----------------------
-
-Since these drivers are so common, special helper functions are available to
-ease the use of these drivers (v4l2-common.h).
-
-The recommended method of adding v4l2_subdev support to an I2C driver is to
-embed the v4l2_subdev struct into the state struct that is created for each
-I2C device instance. Very simple devices have no state struct and in that case
-you can just create a v4l2_subdev directly.
-
-A typical state struct would look like this (where 'chipname' is replaced by
-the name of the chip):
-
-struct chipname_state {
-	struct v4l2_subdev sd;
-	...  /* additional state fields */
-};
-
-Initialize the v4l2_subdev struct as follows:
-
-	v4l2_i2c_subdev_init(&state->sd, client, subdev_ops);
-
-This function will fill in all the fields of v4l2_subdev and ensure that the
-v4l2_subdev and i2c_client both point to one another.
-
-You should also add a helper inline function to go from a v4l2_subdev pointer
-to a chipname_state struct:
-
-static inline struct chipname_state *to_state(struct v4l2_subdev *sd)
-{
-	return container_of(sd, struct chipname_state, sd);
-}
-
-Use this to go from the v4l2_subdev struct to the i2c_client struct:
-
-	struct i2c_client *client = v4l2_get_subdevdata(sd);
-
-And this to go from an i2c_client to a v4l2_subdev struct:
-
-	struct v4l2_subdev *sd = i2c_get_clientdata(client);
-
-Make sure to call v4l2_device_unregister_subdev(sd) when the remove() callback
-is called. This will unregister the sub-device from the bridge driver. It is
-safe to call this even if the sub-device was never registered.
-
-You need to do this because when the bridge driver destroys the i2c adapter
-the remove() callbacks are called of the i2c devices on that adapter.
-After that the corresponding v4l2_subdev structures are invalid, so they
-have to be unregistered first. Calling v4l2_device_unregister_subdev(sd)
-from the remove() callback ensures that this is always done correctly.
-
-
-The bridge driver also has some helper functions it can use:
-
-struct v4l2_subdev *sd = v4l2_i2c_new_subdev(v4l2_dev, adapter,
-	       "module_foo", "chipid", 0x36, NULL);
-
-This loads the given module (can be NULL if no module needs to be loaded) and
-calls i2c_new_device() with the given i2c_adapter and chip/address arguments.
-If all goes well, then it registers the subdev with the v4l2_device.
-
-You can also use the last argument of v4l2_i2c_new_subdev() to pass an array
-of possible I2C addresses that it should probe. These probe addresses are
-only used if the previous argument is 0. A non-zero argument means that you
-know the exact i2c address so in that case no probing will take place.
-
-Both functions return NULL if something went wrong.
-
-Note that the chipid you pass to v4l2_i2c_new_subdev() is usually
-the same as the module name. It allows you to specify a chip variant, e.g.
-"saa7114" or "saa7115". In general though the i2c driver autodetects this.
-The use of chipid is something that needs to be looked at more closely at a
-later date. It differs between i2c drivers and as such can be confusing.
-To see which chip variants are supported you can look in the i2c driver code
-for the i2c_device_id table. This lists all the possibilities.
-
-There are two more helper functions:
-
-v4l2_i2c_new_subdev_cfg: this function adds new irq and platform_data
-arguments and has both 'addr' and 'probed_addrs' arguments: if addr is not
-0 then that will be used (non-probing variant), otherwise the probed_addrs
-are probed.
-
-For example: this will probe for address 0x10:
-
-struct v4l2_subdev *sd = v4l2_i2c_new_subdev_cfg(v4l2_dev, adapter,
-	       "module_foo", "chipid", 0, NULL, 0, I2C_ADDRS(0x10));
-
-v4l2_i2c_new_subdev_board uses an i2c_board_info struct which is passed
-to the i2c driver and replaces the irq, platform_data and addr arguments.
-
-If the subdev supports the s_config core ops, then that op is called with
-the irq and platform_data arguments after the subdev was setup. The older
-v4l2_i2c_new_(probed_)subdev functions will call s_config as well, but with
-irq set to 0 and platform_data set to NULL.
-
-struct video_device
--------------------
-
-The actual device nodes in the /dev directory are created using the
-video_device struct (v4l2-dev.h). This struct can either be allocated
-dynamically or embedded in a larger struct.
-
-To allocate it dynamically use:
-
-	struct video_device *vdev = video_device_alloc();
-
-	if (vdev == NULL)
-		return -ENOMEM;
-
-	vdev->release = video_device_release;
-
-If you embed it in a larger struct, then you must set the release()
-callback to your own function:
-
-	struct video_device *vdev = &my_vdev->vdev;
-
-	vdev->release = my_vdev_release;
-
-The release callback must be set and it is called when the last user
-of the video device exits.
-
-The default video_device_release() callback just calls kfree to free the
-allocated memory.
-
-There is also a video_device_release_empty() function that does nothing
-(is empty) and can be used if the struct is embedded and there is nothing
-to do when it is released.
-
-You should also set these fields:
-
-- v4l2_dev: must be set to the v4l2_device parent device.
-
-- name: set to something descriptive and unique.
-
-- vfl_dir: set this to VFL_DIR_RX for capture devices (VFL_DIR_RX has value 0,
-  so this is normally already the default), set to VFL_DIR_TX for output
-  devices and VFL_DIR_M2M for mem2mem (codec) devices.
-
-- fops: set to the v4l2_file_operations struct.
-
-- ioctl_ops: if you use the v4l2_ioctl_ops to simplify ioctl maintenance
-  (highly recommended to use this and it might become compulsory in the
-  future!), then set this to your v4l2_ioctl_ops struct. The vfl_type and
-  vfl_dir fields are used to disable ops that do not match the type/dir
-  combination. E.g. VBI ops are disabled for non-VBI nodes, and output ops
-  are disabled for a capture device. This makes it possible to provide
-  just one v4l2_ioctl_ops struct for both vbi and video nodes.
-
-- lock: leave to NULL if you want to do all the locking in the driver.
-  Otherwise you give it a pointer to a struct mutex_lock and before the
-  unlocked_ioctl file operation is called this lock will be taken by the
-  core and released afterwards. See the next section for more details.
-
-- queue: a pointer to the struct vb2_queue associated with this device node.
-  If queue is non-NULL, and queue->lock is non-NULL, then queue->lock is
-  used for the queuing ioctls (VIDIOC_REQBUFS, CREATE_BUFS, QBUF, DQBUF,
-  QUERYBUF, PREPARE_BUF, STREAMON and STREAMOFF) instead of the lock above.
-  That way the vb2 queuing framework does not have to wait for other ioctls.
-  This queue pointer is also used by the vb2 helper functions to check for
-  queuing ownership (i.e. is the filehandle calling it allowed to do the
-  operation).
-
-- prio: keeps track of the priorities. Used to implement VIDIOC_G/S_PRIORITY.
-  If left to NULL, then it will use the struct v4l2_prio_state in v4l2_device.
-  If you want to have a separate priority state per (group of) device node(s),
-  then you can point it to your own struct v4l2_prio_state.
-
-- dev_parent: you only set this if v4l2_device was registered with NULL as
-  the parent device struct. This only happens in cases where one hardware
-  device has multiple PCI devices that all share the same v4l2_device core.
-
-  The cx88 driver is an example of this: one core v4l2_device struct, but
-  it is used by both a raw video PCI device (cx8800) and a MPEG PCI device
-  (cx8802). Since the v4l2_device cannot be associated with two PCI devices
-  at the same time it is setup without a parent device. But when the struct
-  video_device is initialized you *do* know which parent PCI device to use and
-  so you set dev_device to the correct PCI device.
-
-If you use v4l2_ioctl_ops, then you should set .unlocked_ioctl to video_ioctl2
-in your v4l2_file_operations struct.
-
-Do not use .ioctl! This is deprecated and will go away in the future.
-
-In some cases you want to tell the core that a function you had specified in
-your v4l2_ioctl_ops should be ignored. You can mark such ioctls by calling this
-function before video_device_register is called:
-
-void v4l2_disable_ioctl(struct video_device *vdev, unsigned int cmd);
-
-This tends to be needed if based on external factors (e.g. which card is
-being used) you want to turns off certain features in v4l2_ioctl_ops without
-having to make a new struct.
-
-The v4l2_file_operations struct is a subset of file_operations. The main
-difference is that the inode argument is omitted since it is never used.
-
-If integration with the media framework is needed, you must initialize the
-media_entity struct embedded in the video_device struct (entity field) by
-calling media_entity_pads_init():
-
-	struct media_pad *pad = &my_vdev->pad;
-	int err;
-
-	err = media_entity_pads_init(&vdev->entity, 1, pad);
-
-The pads array must have been previously initialized. There is no need to
-manually set the struct media_entity type and name fields.
-
-A reference to the entity will be automatically acquired/released when the
-video device is opened/closed.
-
-ioctls and locking
-------------------
-
-The V4L core provides optional locking services. The main service is the
-lock field in struct video_device, which is a pointer to a mutex. If you set
-this pointer, then that will be used by unlocked_ioctl to serialize all ioctls.
-
-If you are using the videobuf2 framework, then there is a second lock that you
-can set: video_device->queue->lock. If set, then this lock will be used instead
-of video_device->lock to serialize all queuing ioctls (see the previous section
-for the full list of those ioctls).
-
-The advantage of using a different lock for the queuing ioctls is that for some
-drivers (particularly USB drivers) certain commands such as setting controls
-can take a long time, so you want to use a separate lock for the buffer queuing
-ioctls. That way your VIDIOC_DQBUF doesn't stall because the driver is busy
-changing the e.g. exposure of the webcam.
-
-Of course, you can always do all the locking yourself by leaving both lock
-pointers at NULL.
-
-If you use the old videobuf then you must pass the video_device lock to the
-videobuf queue initialize function: if videobuf has to wait for a frame to
-arrive, then it will temporarily unlock the lock and relock it afterwards. If
-your driver also waits in the code, then you should do the same to allow other
-processes to access the device node while the first process is waiting for
-something.
-
-In the case of videobuf2 you will need to implement the wait_prepare and
-wait_finish callbacks to unlock/lock if applicable. If you use the queue->lock
-pointer, then you can use the helper functions vb2_ops_wait_prepare/finish.
-
-The implementation of a hotplug disconnect should also take the lock from
-video_device before calling v4l2_device_disconnect. If you are also using
-video_device->queue->lock, then you have to first lock video_device->queue->lock
-followed by video_device->lock. That way you can be sure no ioctl is running
-when you call v4l2_device_disconnect.
-
-video_device registration
--------------------------
-
-Next you register the video device: this will create the character device
-for you.
-
-	err = video_register_device(vdev, VFL_TYPE_GRABBER, -1);
-	if (err) {
-		video_device_release(vdev); /* or kfree(my_vdev); */
-		return err;
-	}
-
-If the v4l2_device parent device has a non-NULL mdev field, the video device
-entity will be automatically registered with the media device.
-
-Which device is registered depends on the type argument. The following
-types exist:
-
-VFL_TYPE_GRABBER: videoX for video input/output devices
-VFL_TYPE_VBI: vbiX for vertical blank data (i.e. closed captions, teletext)
-VFL_TYPE_RADIO: radioX for radio tuners
-VFL_TYPE_SDR: swradioX for Software Defined Radio tuners
-
-The last argument gives you a certain amount of control over the device
-device node number used (i.e. the X in videoX). Normally you will pass -1
-to let the v4l2 framework pick the first free number. But sometimes users
-want to select a specific node number. It is common that drivers allow
-the user to select a specific device node number through a driver module
-option. That number is then passed to this function and video_register_device
-will attempt to select that device node number. If that number was already
-in use, then the next free device node number will be selected and it
-will send a warning to the kernel log.
-
-Another use-case is if a driver creates many devices. In that case it can
-be useful to place different video devices in separate ranges. For example,
-video capture devices start at 0, video output devices start at 16.
-So you can use the last argument to specify a minimum device node number
-and the v4l2 framework will try to pick the first free number that is equal
-or higher to what you passed. If that fails, then it will just pick the
-first free number.
-
-Since in this case you do not care about a warning about not being able
-to select the specified device node number, you can call the function
-video_register_device_no_warn() instead.
-
-Whenever a device node is created some attributes are also created for you.
-If you look in /sys/class/video4linux you see the devices. Go into e.g.
-video0 and you will see 'name', 'dev_debug' and 'index' attributes. The 'name'
-attribute is the 'name' field of the video_device struct. The 'dev_debug' attribute
-can be used to enable core debugging. See the next section for more detailed
-information on this.
-
-The 'index' attribute is the index of the device node: for each call to
-video_register_device() the index is just increased by 1. The first video
-device node you register always starts with index 0.
-
-Users can setup udev rules that utilize the index attribute to make fancy
-device names (e.g. 'mpegX' for MPEG video capture device nodes).
-
-After the device was successfully registered, then you can use these fields:
-
-- vfl_type: the device type passed to video_register_device.
-- minor: the assigned device minor number.
-- num: the device node number (i.e. the X in videoX).
-- index: the device index number.
-
-If the registration failed, then you need to call video_device_release()
-to free the allocated video_device struct, or free your own struct if the
-video_device was embedded in it. The vdev->release() callback will never
-be called if the registration failed, nor should you ever attempt to
-unregister the device if the registration failed.
-
-video device debugging
-----------------------
-
-The 'dev_debug' attribute that is created for each video, vbi, radio or swradio
-device in /sys/class/video4linux/<devX>/ allows you to enable logging of
-file operations.
-
-It is a bitmask and the following bits can be set:
-
-0x01: Log the ioctl name and error code. VIDIOC_(D)QBUF ioctls are only logged
-      if bit 0x08 is also set.
-0x02: Log the ioctl name arguments and error code. VIDIOC_(D)QBUF ioctls are
-      only logged if bit 0x08 is also set.
-0x04: Log the file operations open, release, read, write, mmap and
-      get_unmapped_area. The read and write operations are only logged if
-      bit 0x08 is also set.
-0x08: Log the read and write file operations and the VIDIOC_QBUF and
-      VIDIOC_DQBUF ioctls.
-0x10: Log the poll file operation.
-
-video_device cleanup
---------------------
-
-When the video device nodes have to be removed, either during the unload
-of the driver or because the USB device was disconnected, then you should
-unregister them:
-
-	video_unregister_device(vdev);
-
-This will remove the device nodes from sysfs (causing udev to remove them
-from /dev).
-
-After video_unregister_device() returns no new opens can be done. However,
-in the case of USB devices some application might still have one of these
-device nodes open. So after the unregister all file operations (except
-release, of course) will return an error as well.
-
-When the last user of the video device node exits, then the vdev->release()
-callback is called and you can do the final cleanup there.
-
-Don't forget to cleanup the media entity associated with the video device if
-it has been initialized:
-
-	media_entity_cleanup(&vdev->entity);
-
-This can be done from the release callback.
-
-
-video_device helper functions
------------------------------
-
-There are a few useful helper functions:
-
-- file/video_device private data
-
-You can set/get driver private data in the video_device struct using:
-
-void *video_get_drvdata(struct video_device *vdev);
-void video_set_drvdata(struct video_device *vdev, void *data);
-
-Note that you can safely call video_set_drvdata() before calling
-video_register_device().
-
-And this function:
-
-struct video_device *video_devdata(struct file *file);
-
-returns the video_device belonging to the file struct.
-
-The video_drvdata function combines video_get_drvdata with video_devdata:
-
-void *video_drvdata(struct file *file);
-
-You can go from a video_device struct to the v4l2_device struct using:
-
-struct v4l2_device *v4l2_dev = vdev->v4l2_dev;
-
-- Device node name
-
-The video_device node kernel name can be retrieved using
-
-const char *video_device_node_name(struct video_device *vdev);
-
-The name is used as a hint by userspace tools such as udev. The function
-should be used where possible instead of accessing the video_device::num and
-video_device::minor fields.
-
-
-video buffer helper functions
------------------------------
-
-The v4l2 core API provides a set of standard methods (called "videobuf")
-for dealing with video buffers. Those methods allow a driver to implement
-read(), mmap() and overlay() in a consistent way.  There are currently
-methods for using video buffers on devices that supports DMA with
-scatter/gather method (videobuf-dma-sg), DMA with linear access
-(videobuf-dma-contig), and vmalloced buffers, mostly used on USB drivers
-(videobuf-vmalloc).
-
-Please see Documentation/video4linux/videobuf for more information on how
-to use the videobuf layer.
-
-struct v4l2_fh
---------------
-
-struct v4l2_fh provides a way to easily keep file handle specific data
-that is used by the V4L2 framework. New drivers must use struct v4l2_fh
-since it is also used to implement priority handling (VIDIOC_G/S_PRIORITY).
-
-The users of v4l2_fh (in the V4L2 framework, not the driver) know
-whether a driver uses v4l2_fh as its file->private_data pointer by
-testing the V4L2_FL_USES_V4L2_FH bit in video_device->flags. This bit is
-set whenever v4l2_fh_init() is called.
-
-struct v4l2_fh is allocated as a part of the driver's own file handle
-structure and file->private_data is set to it in the driver's open
-function by the driver.
-
-In many cases the struct v4l2_fh will be embedded in a larger structure.
-In that case you should call v4l2_fh_init+v4l2_fh_add in open() and
-v4l2_fh_del+v4l2_fh_exit in release().
-
-Drivers can extract their own file handle structure by using the container_of
-macro. Example:
-
-struct my_fh {
-	int blah;
-	struct v4l2_fh fh;
-};
-
-...
-
-int my_open(struct file *file)
-{
-	struct my_fh *my_fh;
-	struct video_device *vfd;
-	int ret;
-
-	...
-
-	my_fh = kzalloc(sizeof(*my_fh), GFP_KERNEL);
-
-	...
-
-	v4l2_fh_init(&my_fh->fh, vfd);
-
-	...
-
-	file->private_data = &my_fh->fh;
-	v4l2_fh_add(&my_fh->fh);
-	return 0;
-}
-
-int my_release(struct file *file)
-{
-	struct v4l2_fh *fh = file->private_data;
-	struct my_fh *my_fh = container_of(fh, struct my_fh, fh);
-
-	...
-	v4l2_fh_del(&my_fh->fh);
-	v4l2_fh_exit(&my_fh->fh);
-	kfree(my_fh);
-	return 0;
-}
-
-Below is a short description of the v4l2_fh functions used:
-
-void v4l2_fh_init(struct v4l2_fh *fh, struct video_device *vdev)
-
-  Initialise the file handle. This *MUST* be performed in the driver's
-  v4l2_file_operations->open() handler.
-
-void v4l2_fh_add(struct v4l2_fh *fh)
-
-  Add a v4l2_fh to video_device file handle list. Must be called once the
-  file handle is completely initialized.
-
-void v4l2_fh_del(struct v4l2_fh *fh)
-
-  Unassociate the file handle from video_device(). The file handle
-  exit function may now be called.
-
-void v4l2_fh_exit(struct v4l2_fh *fh)
-
-  Uninitialise the file handle. After uninitialisation the v4l2_fh
-  memory can be freed.
-
-
-If struct v4l2_fh is not embedded, then you can use these helper functions:
-
-int v4l2_fh_open(struct file *filp)
-
-  This allocates a struct v4l2_fh, initializes it and adds it to the struct
-  video_device associated with the file struct.
-
-int v4l2_fh_release(struct file *filp)
-
-  This deletes it from the struct video_device associated with the file
-  struct, uninitialised the v4l2_fh and frees it.
-
-These two functions can be plugged into the v4l2_file_operation's open() and
-release() ops.
-
-
-Several drivers need to do something when the first file handle is opened and
-when the last file handle closes. Two helper functions were added to check
-whether the v4l2_fh struct is the only open filehandle of the associated
-device node:
-
-int v4l2_fh_is_singular(struct v4l2_fh *fh)
-
-  Returns 1 if the file handle is the only open file handle, else 0.
-
-int v4l2_fh_is_singular_file(struct file *filp)
-
-  Same, but it calls v4l2_fh_is_singular with filp->private_data.
-
-
-V4L2 events
------------
-
-The V4L2 events provide a generic way to pass events to user space.
-The driver must use v4l2_fh to be able to support V4L2 events.
-
-Events are defined by a type and an optional ID. The ID may refer to a V4L2
-object such as a control ID. If unused, then the ID is 0.
-
-When the user subscribes to an event the driver will allocate a number of
-kevent structs for that event. So every (type, ID) event tuple will have
-its own set of kevent structs. This guarantees that if a driver is generating
-lots of events of one type in a short time, then that will not overwrite
-events of another type.
-
-But if you get more events of one type than the number of kevents that were
-reserved, then the oldest event will be dropped and the new one added.
-
-Furthermore, the internal struct v4l2_subscribed_event has merge() and
-replace() callbacks which drivers can set. These callbacks are called when
-a new event is raised and there is no more room. The replace() callback
-allows you to replace the payload of the old event with that of the new event,
-merging any relevant data from the old payload into the new payload that
-replaces it. It is called when this event type has only one kevent struct
-allocated. The merge() callback allows you to merge the oldest event payload
-into that of the second-oldest event payload. It is called when there are two
-or more kevent structs allocated.
-
-This way no status information is lost, just the intermediate steps leading
-up to that state.
-
-A good example of these replace/merge callbacks is in v4l2-event.c:
-ctrls_replace() and ctrls_merge() callbacks for the control event.
-
-Note: these callbacks can be called from interrupt context, so they must be
-fast.
-
-Useful functions:
-
-void v4l2_event_queue(struct video_device *vdev, const struct v4l2_event *ev)
-
-  Queue events to video device. The driver's only responsibility is to fill
-  in the type and the data fields. The other fields will be filled in by
-  V4L2.
-
-int v4l2_event_subscribe(struct v4l2_fh *fh,
-			 struct v4l2_event_subscription *sub, unsigned elems,
-			 const struct v4l2_subscribed_event_ops *ops)
-
-  The video_device->ioctl_ops->vidioc_subscribe_event must check the driver
-  is able to produce events with specified event id. Then it calls
-  v4l2_event_subscribe() to subscribe the event.
-
-  The elems argument is the size of the event queue for this event. If it is 0,
-  then the framework will fill in a default value (this depends on the event
-  type).
-
-  The ops argument allows the driver to specify a number of callbacks:
-  * add:     called when a new listener gets added (subscribing to the same
-             event twice will only cause this callback to get called once)
-  * del:     called when a listener stops listening
-  * replace: replace event 'old' with event 'new'.
-  * merge:   merge event 'old' into event 'new'.
-  All 4 callbacks are optional, if you don't want to specify any callbacks
-  the ops argument itself maybe NULL.
-
-int v4l2_event_unsubscribe(struct v4l2_fh *fh,
-			   struct v4l2_event_subscription *sub)
-
-  vidioc_unsubscribe_event in struct v4l2_ioctl_ops. A driver may use
-  v4l2_event_unsubscribe() directly unless it wants to be involved in
-  unsubscription process.
-
-  The special type V4L2_EVENT_ALL may be used to unsubscribe all events. The
-  drivers may want to handle this in a special way.
-
-int v4l2_event_pending(struct v4l2_fh *fh)
-
-  Returns the number of pending events. Useful when implementing poll.
-
-Events are delivered to user space through the poll system call. The driver
-can use v4l2_fh->wait (a wait_queue_head_t) as the argument for poll_wait().
-
-There are standard and private events. New standard events must use the
-smallest available event type. The drivers must allocate their events from
-their own class starting from class base. Class base is
-V4L2_EVENT_PRIVATE_START + n * 1000 where n is the lowest available number.
-The first event type in the class is reserved for future use, so the first
-available event type is 'class base + 1'.
-
-An example on how the V4L2 events may be used can be found in the OMAP
-3 ISP driver (drivers/media/platform/omap3isp).
-
-A subdev can directly send an event to the v4l2_device notify function with
-V4L2_DEVICE_NOTIFY_EVENT. This allows the bridge to map the subdev that sends
-the event to the video node(s) associated with the subdev that need to be
-informed about such an event.
-
-V4L2 clocks
------------
-
-Many subdevices, like camera sensors, TV decoders and encoders, need a clock
-signal to be supplied by the system. Often this clock is supplied by the
-respective bridge device. The Linux kernel provides a Common Clock Framework for
-this purpose. However, it is not (yet) available on all architectures. Besides,
-the nature of the multi-functional (clock, data + synchronisation, I2C control)
-connection of subdevices to the system might impose special requirements on the
-clock API usage. E.g. V4L2 has to support clock provider driver unregistration
-while a subdevice driver is holding a reference to the clock. For these reasons
-a V4L2 clock helper API has been developed and is provided to bridge and
-subdevice drivers.
-
-The API consists of two parts: two functions to register and unregister a V4L2
-clock source: v4l2_clk_register() and v4l2_clk_unregister() and calls to control
-a clock object, similar to the respective generic clock API calls:
-v4l2_clk_get(), v4l2_clk_put(), v4l2_clk_enable(), v4l2_clk_disable(),
-v4l2_clk_get_rate(), and v4l2_clk_set_rate(). Clock suppliers have to provide
-clock operations that will be called when clock users invoke respective API
-methods.
-
-It is expected that once the CCF becomes available on all relevant
-architectures this API will be removed.

-An introduction to the videobuf layer
-Jonathan Corbet <corbet@lwn.net>
-Current as of 2.6.33
-
-The videobuf layer functions as a sort of glue layer between a V4L2 driver
-and user space.  It handles the allocation and management of buffers for
-the storage of video frames.  There is a set of functions which can be used
-to implement many of the standard POSIX I/O system calls, including read(),
-poll(), and, happily, mmap().  Another set of functions can be used to
-implement the bulk of the V4L2 ioctl() calls related to streaming I/O,
-including buffer allocation, queueing and dequeueing, and streaming
-control.  Using videobuf imposes a few design decisions on the driver
-author, but the payback comes in the form of reduced code in the driver and
-a consistent implementation of the V4L2 user-space API.
-
-Buffer types
-
-Not all video devices use the same kind of buffers.  In fact, there are (at
-least) three common variations:
-
- - Buffers which are scattered in both the physical and (kernel) virtual
-   address spaces.  (Almost) all user-space buffers are like this, but it
-   makes great sense to allocate kernel-space buffers this way as well when
-   it is possible.  Unfortunately, it is not always possible; working with
-   this kind of buffer normally requires hardware which can do
-   scatter/gather DMA operations.
-
- - Buffers which are physically scattered, but which are virtually
-   contiguous; buffers allocated with vmalloc(), in other words.  These
-   buffers are just as hard to use for DMA operations, but they can be
-   useful in situations where DMA is not available but virtually-contiguous
-   buffers are convenient.
-
- - Buffers which are physically contiguous.  Allocation of this kind of
-   buffer can be unreliable on fragmented systems, but simpler DMA
-   controllers cannot deal with anything else.
-
-Videobuf can work with all three types of buffers, but the driver author
-must pick one at the outset and design the driver around that decision.
-
-[It's worth noting that there's a fourth kind of buffer: "overlay" buffers
-which are located within the system's video memory.  The overlay
-functionality is considered to be deprecated for most use, but it still
-shows up occasionally in system-on-chip drivers where the performance
-benefits merit the use of this technique.  Overlay buffers can be handled
-as a form of scattered buffer, but there are very few implementations in
-the kernel and a description of this technique is currently beyond the
-scope of this document.]
-
-Data structures, callbacks, and initialization
-
-Depending on which type of buffers are being used, the driver should
-include one of the following files:
-
-    <media/videobuf-dma-sg.h>		/* Physically scattered */
-    <media/videobuf-vmalloc.h>		/* vmalloc() buffers	*/
-    <media/videobuf-dma-contig.h>	/* Physically contiguous */
-
-The driver's data structure describing a V4L2 device should include a
-struct videobuf_queue instance for the management of the buffer queue,
-along with a list_head for the queue of available buffers.  There will also
-need to be an interrupt-safe spinlock which is used to protect (at least)
-the queue.
-
-The next step is to write four simple callbacks to help videobuf deal with
-the management of buffers:
-
-    struct videobuf_queue_ops {
-	int (*buf_setup)(struct videobuf_queue *q,
-			 unsigned int *count, unsigned int *size);
-	int (*buf_prepare)(struct videobuf_queue *q,
-			   struct videobuf_buffer *vb,
-			   enum v4l2_field field);
-	void (*buf_queue)(struct videobuf_queue *q,
-			  struct videobuf_buffer *vb);
-	void (*buf_release)(struct videobuf_queue *q,
-			    struct videobuf_buffer *vb);
-    };
-
-buf_setup() is called early in the I/O process, when streaming is being
-initiated; its purpose is to tell videobuf about the I/O stream.  The count
-parameter will be a suggested number of buffers to use; the driver should
-check it for rationality and adjust it if need be.  As a practical rule, a
-minimum of two buffers are needed for proper streaming, and there is
-usually a maximum (which cannot exceed 32) which makes sense for each
-device.  The size parameter should be set to the expected (maximum) size
-for each frame of data.
-
-Each buffer (in the form of a struct videobuf_buffer pointer) will be
-passed to buf_prepare(), which should set the buffer's size, width, height,
-and field fields properly.  If the buffer's state field is
-VIDEOBUF_NEEDS_INIT, the driver should pass it to:
-
-    int videobuf_iolock(struct videobuf_queue* q, struct videobuf_buffer *vb,
-			struct v4l2_framebuffer *fbuf);
-
-Among other things, this call will usually allocate memory for the buffer.
-Finally, the buf_prepare() function should set the buffer's state to
-VIDEOBUF_PREPARED.
-
-When a buffer is queued for I/O, it is passed to buf_queue(), which should
-put it onto the driver's list of available buffers and set its state to
-VIDEOBUF_QUEUED.  Note that this function is called with the queue spinlock
-held; if it tries to acquire it as well things will come to a screeching
-halt.  Yes, this is the voice of experience.  Note also that videobuf may
-wait on the first buffer in the queue; placing other buffers in front of it
-could again gum up the works.  So use list_add_tail() to enqueue buffers.
-
-Finally, buf_release() is called when a buffer is no longer intended to be
-used.  The driver should ensure that there is no I/O active on the buffer,
-then pass it to the appropriate free routine(s):
-
-    /* Scatter/gather drivers */
-    int videobuf_dma_unmap(struct videobuf_queue *q,
-			   struct videobuf_dmabuf *dma);
-    int videobuf_dma_free(struct videobuf_dmabuf *dma);
-
-    /* vmalloc drivers */
-    void videobuf_vmalloc_free (struct videobuf_buffer *buf);
-
-    /* Contiguous drivers */
-    void videobuf_dma_contig_free(struct videobuf_queue *q,
-				  struct videobuf_buffer *buf);
-
-One way to ensure that a buffer is no longer under I/O is to pass it to:
-
-    int videobuf_waiton(struct videobuf_buffer *vb, int non_blocking, int intr);
-
-Here, vb is the buffer, non_blocking indicates whether non-blocking I/O
-should be used (it should be zero in the buf_release() case), and intr
-controls whether an interruptible wait is used.
-
-File operations
-
-At this point, much of the work is done; much of the rest is slipping
-videobuf calls into the implementation of the other driver callbacks.  The
-first step is in the open() function, which must initialize the
-videobuf queue.  The function to use depends on the type of buffer used:
-
-    void videobuf_queue_sg_init(struct videobuf_queue *q,
-				struct videobuf_queue_ops *ops,
-				struct device *dev,
-				spinlock_t *irqlock,
-				enum v4l2_buf_type type,
-				enum v4l2_field field,
-				unsigned int msize,
-				void *priv);
-
-    void videobuf_queue_vmalloc_init(struct videobuf_queue *q,
-				struct videobuf_queue_ops *ops,
-				struct device *dev,
-				spinlock_t *irqlock,
-				enum v4l2_buf_type type,
-				enum v4l2_field field,
-				unsigned int msize,
-				void *priv);
-
-    void videobuf_queue_dma_contig_init(struct videobuf_queue *q,
-				       struct videobuf_queue_ops *ops,
-				       struct device *dev,
-				       spinlock_t *irqlock,
-				       enum v4l2_buf_type type,
-				       enum v4l2_field field,
-				       unsigned int msize,
-				       void *priv);
-
-In each case, the parameters are the same: q is the queue structure for the
-device, ops is the set of callbacks as described above, dev is the device
-structure for this video device, irqlock is an interrupt-safe spinlock to
-protect access to the data structures, type is the buffer type used by the
-device (cameras will use V4L2_BUF_TYPE_VIDEO_CAPTURE, for example), field
-describes which field is being captured (often V4L2_FIELD_NONE for
-progressive devices), msize is the size of any containing structure used
-around struct videobuf_buffer, and priv is a private data pointer which
-shows up in the priv_data field of struct videobuf_queue.  Note that these
-are void functions which, evidently, are immune to failure.
-
-V4L2 capture drivers can be written to support either of two APIs: the
-read() system call and the rather more complicated streaming mechanism.  As
-a general rule, it is necessary to support both to ensure that all
-applications have a chance of working with the device.  Videobuf makes it
-easy to do that with the same code.  To implement read(), the driver need
-only make a call to one of:
-
-    ssize_t videobuf_read_one(struct videobuf_queue *q,
-			      char __user *data, size_t count,
-			      loff_t *ppos, int nonblocking);
-
-    ssize_t videobuf_read_stream(struct videobuf_queue *q,
-				 char __user *data, size_t count,
-				 loff_t *ppos, int vbihack, int nonblocking);
-
-Either one of these functions will read frame data into data, returning the
-amount actually read; the difference is that videobuf_read_one() will only
-read a single frame, while videobuf_read_stream() will read multiple frames
-if they are needed to satisfy the count requested by the application.  A
-typical driver read() implementation will start the capture engine, call
-one of the above functions, then stop the engine before returning (though a
-smarter implementation might leave the engine running for a little while in
-anticipation of another read() call happening in the near future).
-
-The poll() function can usually be implemented with a direct call to:
-
-    unsigned int videobuf_poll_stream(struct file *file,
-				      struct videobuf_queue *q,
-				      poll_table *wait);
-
-Note that the actual wait queue eventually used will be the one associated
-with the first available buffer.
-
-When streaming I/O is done to kernel-space buffers, the driver must support
-the mmap() system call to enable user space to access the data.  In many
-V4L2 drivers, the often-complex mmap() implementation simplifies to a
-single call to:
-
-    int videobuf_mmap_mapper(struct videobuf_queue *q,
-			     struct vm_area_struct *vma);
-
-Everything else is handled by the videobuf code.
-
-The release() function requires two separate videobuf calls:
-
-    void videobuf_stop(struct videobuf_queue *q);
-    int videobuf_mmap_free(struct videobuf_queue *q);
-
-The call to videobuf_stop() terminates any I/O in progress - though it is
-still up to the driver to stop the capture engine.  The call to
-videobuf_mmap_free() will ensure that all buffers have been unmapped; if
-so, they will all be passed to the buf_release() callback.  If buffers
-remain mapped, videobuf_mmap_free() returns an error code instead.  The
-purpose is clearly to cause the closing of the file descriptor to fail if
-buffers are still mapped, but every driver in the 2.6.32 kernel cheerfully
-ignores its return value.
-
-ioctl() operations
-
-The V4L2 API includes a very long list of driver callbacks to respond to
-the many ioctl() commands made available to user space.  A number of these
-- those associated with streaming I/O - turn almost directly into videobuf
-calls.  The relevant helper functions are:
-
-    int videobuf_reqbufs(struct videobuf_queue *q,
-			 struct v4l2_requestbuffers *req);
-    int videobuf_querybuf(struct videobuf_queue *q, struct v4l2_buffer *b);
-    int videobuf_qbuf(struct videobuf_queue *q, struct v4l2_buffer *b);
-    int videobuf_dqbuf(struct videobuf_queue *q, struct v4l2_buffer *b,
-		       int nonblocking);
-    int videobuf_streamon(struct videobuf_queue *q);
-    int videobuf_streamoff(struct videobuf_queue *q);
-
-So, for example, a VIDIOC_REQBUFS call turns into a call to the driver's
-vidioc_reqbufs() callback which, in turn, usually only needs to locate the
-proper struct videobuf_queue pointer and pass it to videobuf_reqbufs().
-These support functions can replace a great deal of buffer management
-boilerplate in a lot of V4L2 drivers.
-
-The vidioc_streamon() and vidioc_streamoff() functions will be a bit more
-complex, of course, since they will also need to deal with starting and
-stopping the capture engine.
-
-Buffer allocation
-
-Thus far, we have talked about buffers, but have not looked at how they are
-allocated.  The scatter/gather case is the most complex on this front.  For
-allocation, the driver can leave buffer allocation entirely up to the
-videobuf layer; in this case, buffers will be allocated as anonymous
-user-space pages and will be very scattered indeed.  If the application is
-using user-space buffers, no allocation is needed; the videobuf layer will
-take care of calling get_user_pages() and filling in the scatterlist array.
-
-If the driver needs to do its own memory allocation, it should be done in
-the vidioc_reqbufs() function, *after* calling videobuf_reqbufs().  The
-first step is a call to:
-
-    struct videobuf_dmabuf *videobuf_to_dma(struct videobuf_buffer *buf);
-
-The returned videobuf_dmabuf structure (defined in
-<media/videobuf-dma-sg.h>) includes a couple of relevant fields:
-
-    struct scatterlist  *sglist;
-    int                 sglen;
-
-The driver must allocate an appropriately-sized scatterlist array and
-populate it with pointers to the pieces of the allocated buffer; sglen
-should be set to the length of the array.
-
-Drivers using the vmalloc() method need not (and cannot) concern themselves
-with buffer allocation at all; videobuf will handle those details.  The
-same is normally true of contiguous-DMA drivers as well; videobuf will
-allocate the buffers (with dma_alloc_coherent()) when it sees fit.  That
-means that these drivers may be trying to do high-order allocations at any
-time, an operation which is not always guaranteed to work.  Some drivers
-play tricks by allocating DMA space at system boot time; videobuf does not
-currently play well with those drivers.
-
-As of 2.6.31, contiguous-DMA drivers can work with a user-supplied buffer,
-as long as that buffer is physically contiguous.  Normal user-space
-allocations will not meet that criterion, but buffers obtained from other
-kernel drivers, or those contained within huge pages, will work with these
-drivers.
-
-Filling the buffers
-
-The final part of a videobuf implementation has no direct callback - it's
-the portion of the code which actually puts frame data into the buffers,
-usually in response to interrupts from the device.  For all types of
-drivers, this process works approximately as follows:
-
- - Obtain the next available buffer and make sure that somebody is actually
-   waiting for it.
-
- - Get a pointer to the memory and put video data there.
-
- - Mark the buffer as done and wake up the process waiting for it.
-
-Step (1) above is done by looking at the driver-managed list_head structure
-- the one which is filled in the buf_queue() callback.  Because starting
-the engine and enqueueing buffers are done in separate steps, it's possible
-for the engine to be running without any buffers available - in the
-vmalloc() case especially.  So the driver should be prepared for the list
-to be empty.  It is equally possible that nobody is yet interested in the
-buffer; the driver should not remove it from the list or fill it until a
-process is waiting on it.  That test can be done by examining the buffer's
-done field (a wait_queue_head_t structure) with waitqueue_active().
-
-A buffer's state should be set to VIDEOBUF_ACTIVE before being mapped for
-DMA; that ensures that the videobuf layer will not try to do anything with
-it while the device is transferring data.
-
-For scatter/gather drivers, the needed memory pointers will be found in the
-scatterlist structure described above.  Drivers using the vmalloc() method
-can get a memory pointer with:
-
-    void *videobuf_to_vmalloc(struct videobuf_buffer *buf);
-
-For contiguous DMA drivers, the function to use is:
-
-    dma_addr_t videobuf_to_dma_contig(struct videobuf_buffer *buf);
-
-The contiguous DMA API goes out of its way to hide the kernel-space address
-of the DMA buffer from drivers.
-
-The final step is to set the size field of the relevant videobuf_buffer
-structure to the actual size of the captured image, set state to
-VIDEOBUF_DONE, then call wake_up() on the done queue.  At this point, the
-buffer is owned by the videobuf layer and the driver should not touch it
-again.
-
-Developers who are interested in more information can go into the relevant
-header files; there are a few low-level functions declared there which have
-not been talked about here.  Also worthwhile is the vivi driver
-(drivers/media/platform/vivi.c), which is maintained as an example of how V4L2
-drivers should be written.  Vivi only uses the vmalloc() API, but it's good
-enough to get started with.  Note also that all of these calls are exported
-GPL-only, so they will not be available to non-GPL kernel modules.

-Section 1: Configuring the driver
----------------------------------
-
-By default the driver will create a single instance that has a video capture
-device with webcam, TV, S-Video and HDMI inputs, a video output device with
-S-Video and HDMI outputs, one vbi capture device, one vbi output device, one
-radio receiver device, one radio transmitter device and one SDR device.
-
-The number of instances, devices, video inputs and outputs and their types are
-all configurable using the following module options:
-
-n_devs: number of driver instances to create. By default set to 1. Up to 64
-	instances can be created.
-
-node_types: which devices should each driver instance create. An array of
-	hexadecimal values, one for each instance. The default is 0x1d3d.
-	Each value is a bitmask with the following meaning:
-		bit 0: Video Capture node
-		bit 2-3: VBI Capture node: 0 = none, 1 = raw vbi, 2 = sliced vbi, 3 = both
-		bit 4: Radio Receiver node
-		bit 5: Software Defined Radio Receiver node
-		bit 8: Video Output node
-		bit 10-11: VBI Output node: 0 = none, 1 = raw vbi, 2 = sliced vbi, 3 = both
-		bit 12: Radio Transmitter node
-		bit 16: Framebuffer for testing overlays
-
-	So to create four instances, the first two with just one video capture
-	device, the second two with just one video output device you would pass
-	these module options to vivid:
-
-		n_devs=4 node_types=0x1,0x1,0x100,0x100
-
-num_inputs: the number of inputs, one for each instance. By default 4 inputs
-	are created for each video capture device. At most 16 inputs can be created,
-	and there must be at least one.
-
-input_types: the input types for each instance, the default is 0xe4. This defines
-	what the type of each input is when the inputs are created for each driver
-	instance. This is a hexadecimal value with up to 16 pairs of bits, each
-	pair gives the type and bits 0-1 map to input 0, bits 2-3 map to input 1,
-	30-31 map to input 15. Each pair of bits has the following meaning:
-
-		00: this is a webcam input
-		01: this is a TV tuner input
-		10: this is an S-Video input
-		11: this is an HDMI input
-
-	So to create a video capture device with 8 inputs where input 0 is a TV
-	tuner, inputs 1-3 are S-Video inputs and inputs 4-7 are HDMI inputs you
-	would use the following module options:
-
-		num_inputs=8 input_types=0xffa9
-
-num_outputs: the number of outputs, one for each instance. By default 2 outputs
-	are created for each video output device. At most 16 outputs can be
-	created, and there must be at least one.
-
-output_types: the output types for each instance, the default is 0x02. This defines
-	what the type of each output is when the outputs are created for each
-	driver instance. This is a hexadecimal value with up to 16 bits, each bit
-	gives the type and bit 0 maps to output 0, bit 1 maps to output 1, bit
-	15 maps to output 15. The meaning of each bit is as follows:
-
-		0: this is an S-Video output
-		1: this is an HDMI output
-
-	So to create a video output device with 8 outputs where outputs 0-3 are
-	S-Video outputs and outputs 4-7 are HDMI outputs you would use the
-	following module options:
-
-		num_outputs=8 output_types=0xf0
-
-vid_cap_nr: give the desired videoX start number for each video capture device.
-	The default is -1 which will just take the first free number. This allows
-	you to map capture video nodes to specific videoX device nodes. Example:
-
-		n_devs=4 vid_cap_nr=2,4,6,8
-
-	This will attempt to assign /dev/video2 for the video capture device of
-	the first vivid instance, video4 for the next up to video8 for the last
-	instance. If it can't succeed, then it will just take the next free
-	number.
-
-vid_out_nr: give the desired videoX start number for each video output device.
-        The default is -1 which will just take the first free number.
-
-vbi_cap_nr: give the desired vbiX start number for each vbi capture device.
-        The default is -1 which will just take the first free number.
-
-vbi_out_nr: give the desired vbiX start number for each vbi output device.
-        The default is -1 which will just take the first free number.
-
-radio_rx_nr: give the desired radioX start number for each radio receiver device.
-        The default is -1 which will just take the first free number.
-
-radio_tx_nr: give the desired radioX start number for each radio transmitter
-	device. The default is -1 which will just take the first free number.
-
-sdr_cap_nr: give the desired swradioX start number for each SDR capture device.
-        The default is -1 which will just take the first free number.
-
-ccs_cap_mode: specify the allowed video capture crop/compose/scaling combination
-	for each driver instance. Video capture devices can have any combination
-	of cropping, composing and scaling capabilities and this will tell the
-	vivid driver which of those is should emulate. By default the user can
-	select this through controls.
-
-	The value is either -1 (controlled by the user) or a set of three bits,
-	each enabling (1) or disabling (0) one of the features:
-
-		bit 0: Enable crop support. Cropping will take only part of the
-		       incoming picture.
-		bit 1: Enable compose support. Composing will copy the incoming
-		       picture into a larger buffer.
-		bit 2: Enable scaling support. Scaling can scale the incoming
-		       picture. The scaler of the vivid driver can enlarge up
-		       or down to four times the original size. The scaler is
-		       very simple and low-quality. Simplicity and speed were
-		       key, not quality.
-
-	Note that this value is ignored by webcam inputs: those enumerate
-	discrete framesizes and that is incompatible with cropping, composing
-	or scaling.
-
-ccs_out_mode: specify the allowed video output crop/compose/scaling combination
-	for each driver instance. Video output devices can have any combination
-	of cropping, composing and scaling capabilities and this will tell the
-	vivid driver which of those is should emulate. By default the user can
-	select this through controls.
-
-	The value is either -1 (controlled by the user) or a set of three bits,
-	each enabling (1) or disabling (0) one of the features:
-
-		bit 0: Enable crop support. Cropping will take only part of the
-		       outgoing buffer.
-		bit 1: Enable compose support. Composing will copy the incoming
-		       buffer into a larger picture frame.
-		bit 2: Enable scaling support. Scaling can scale the incoming
-		       buffer. The scaler of the vivid driver can enlarge up
-		       or down to four times the original size. The scaler is
-		       very simple and low-quality. Simplicity and speed were
-		       key, not quality.
-
-multiplanar: select whether each device instance supports multi-planar formats,
-	and thus the V4L2 multi-planar API. By default device instances are
-	single-planar.
-
-	This module option can override that for each instance. Values are:
-
-		1: this is a single-planar instance.
-		2: this is a multi-planar instance.
-
-vivid_debug: enable driver debugging info
-
-no_error_inj: if set disable the error injecting controls. This option is
-	needed in order to run a tool like v4l2-compliance. Tools like that
-	exercise all controls including a control like 'Disconnect' which
-	emulates a USB disconnect, making the device inaccessible and so
-	all tests that v4l2-compliance is doing will fail afterwards.
-
-	There may be other situations as well where you want to disable the
-	error injection support of vivid. When this option is set, then the
-	controls that select crop, compose and scale behavior are also
-	removed. Unless overridden by ccs_cap_mode and/or ccs_out_mode the
-	will default to enabling crop, compose and scaling.
-
-Taken together, all these module options allow you to precisely customize
-the driver behavior and test your application with all sorts of permutations.
-It is also very suitable to emulate hardware that is not yet available, e.g.
-when developing software for a new upcoming device.
-
-
-Section 2: Video Capture
-------------------------
-
-This is probably the most frequently used feature. The video capture device
-can be configured by using the module options num_inputs, input_types and
-ccs_cap_mode (see section 1 for more detailed information), but by default
-four inputs are configured: a webcam, a TV tuner, an S-Video and an HDMI
-input, one input for each input type. Those are described in more detail
-below.
-
-Special attention has been given to the rate at which new frames become
-available. The jitter will be around 1 jiffie (that depends on the HZ
-configuration of your kernel, so usually 1/100, 1/250 or 1/1000 of a second),
-but the long-term behavior is exactly following the framerate. So a
-framerate of 59.94 Hz is really different from 60 Hz. If the framerate
-exceeds your kernel's HZ value, then you will get dropped frames, but the
-frame/field sequence counting will keep track of that so the sequence
-count will skip whenever frames are dropped.
-
-
-Section 2.1: Webcam Input
--------------------------
-
-The webcam input supports three framesizes: 320x180, 640x360 and 1280x720. It
-supports frames per second settings of 10, 15, 25, 30, 50 and 60 fps. Which ones
-are available depends on the chosen framesize: the larger the framesize, the
-lower the maximum frames per second.
-
-The initially selected colorspace when you switch to the webcam input will be
-sRGB.
-
-
-Section 2.2: TV and S-Video Inputs
-----------------------------------
-
-The only difference between the TV and S-Video input is that the TV has a
-tuner. Otherwise they behave identically.
-
-These inputs support audio inputs as well: one TV and one Line-In. They
-both support all TV standards. If the standard is queried, then the Vivid
-controls 'Standard Signal Mode' and 'Standard' determine what
-the result will be.
-
-These inputs support all combinations of the field setting. Special care has
-been taken to faithfully reproduce how fields are handled for the different
-TV standards. This is particularly noticeable when generating a horizontally
-moving image so the temporal effect of using interlaced formats becomes clearly
-visible. For 50 Hz standards the top field is the oldest and the bottom field
-is the newest in time. For 60 Hz standards that is reversed: the bottom field
-is the oldest and the top field is the newest in time.
-
-When you start capturing in V4L2_FIELD_ALTERNATE mode the first buffer will
-contain the top field for 50 Hz standards and the bottom field for 60 Hz
-standards. This is what capture hardware does as well.
-
-Finally, for PAL/SECAM standards the first half of the top line contains noise.
-This simulates the Wide Screen Signal that is commonly placed there.
-
-The initially selected colorspace when you switch to the TV or S-Video input
-will be SMPTE-170M.
-
-The pixel aspect ratio will depend on the TV standard. The video aspect ratio
-can be selected through the 'Standard Aspect Ratio' Vivid control.
-Choices are '4x3', '16x9' which will give letterboxed widescreen video and
-'16x9 Anamorphic' which will give full screen squashed anamorphic widescreen
-video that will need to be scaled accordingly.
-
-The TV 'tuner' supports a frequency range of 44-958 MHz. Channels are available
-every 6 MHz, starting from 49.25 MHz. For each channel the generated image
-will be in color for the +/- 0.25 MHz around it, and in grayscale for
-+/- 1 MHz around the channel. Beyond that it is just noise. The VIDIOC_G_TUNER
-ioctl will return 100% signal strength for +/- 0.25 MHz and 50% for +/- 1 MHz.
-It will also return correct afc values to show whether the frequency is too
-low or too high.
-
-The audio subchannels that are returned are MONO for the +/- 1 MHz range around
-a valid channel frequency. When the frequency is within +/- 0.25 MHz of the
-channel it will return either MONO, STEREO, either MONO | SAP (for NTSC) or
-LANG1 | LANG2 (for others), or STEREO | SAP.
-
-Which one is returned depends on the chosen channel, each next valid channel
-will cycle through the possible audio subchannel combinations. This allows
-you to test the various combinations by just switching channels..
-
-Finally, for these inputs the v4l2_timecode struct is filled in in the
-dequeued v4l2_buffer struct.
-
-
-Section 2.3: HDMI Input
------------------------
-
-The HDMI inputs supports all CEA-861 and DMT timings, both progressive and
-interlaced, for pixelclock frequencies between 25 and 600 MHz. The field
-mode for interlaced formats is always V4L2_FIELD_ALTERNATE. For HDMI the
-field order is always top field first, and when you start capturing an
-interlaced format you will receive the top field first.
-
-The initially selected colorspace when you switch to the HDMI input or
-select an HDMI timing is based on the format resolution: for resolutions
-less than or equal to 720x576 the colorspace is set to SMPTE-170M, for
-others it is set to REC-709 (CEA-861 timings) or sRGB (VESA DMT timings).
-
-The pixel aspect ratio will depend on the HDMI timing: for 720x480 is it
-set as for the NTSC TV standard, for 720x576 it is set as for the PAL TV
-standard, and for all others a 1:1 pixel aspect ratio is returned.
-
-The video aspect ratio can be selected through the 'DV Timings Aspect Ratio'
-Vivid control. Choices are 'Source Width x Height' (just use the
-same ratio as the chosen format), '4x3' or '16x9', either of which can
-result in pillarboxed or letterboxed video.
-
-For HDMI inputs it is possible to set the EDID. By default a simple EDID
-is provided. You can only set the EDID for HDMI inputs. Internally, however,
-the EDID is shared between all HDMI inputs.
-
-No interpretation is done of the EDID data.
-
-
-Section 3: Video Output
------------------------
-
-The video output device can be configured by using the module options
-num_outputs, output_types and ccs_out_mode (see section 1 for more detailed
-information), but by default two outputs are configured: an S-Video and an
-HDMI input, one output for each output type. Those are described in more detail
-below.
-
-Like with video capture the framerate is also exact in the long term.
-
-
-Section 3.1: S-Video Output
----------------------------
-
-This output supports audio outputs as well: "Line-Out 1" and "Line-Out 2".
-The S-Video output supports all TV standards.
-
-This output supports all combinations of the field setting.
-
-The initially selected colorspace when you switch to the TV or S-Video input
-will be SMPTE-170M.
-
-
-Section 3.2: HDMI Output
-------------------------
-
-The HDMI output supports all CEA-861 and DMT timings, both progressive and
-interlaced, for pixelclock frequencies between 25 and 600 MHz. The field
-mode for interlaced formats is always V4L2_FIELD_ALTERNATE.
-
-The initially selected colorspace when you switch to the HDMI output or
-select an HDMI timing is based on the format resolution: for resolutions
-less than or equal to 720x576 the colorspace is set to SMPTE-170M, for
-others it is set to REC-709 (CEA-861 timings) or sRGB (VESA DMT timings).
-
-The pixel aspect ratio will depend on the HDMI timing: for 720x480 is it
-set as for the NTSC TV standard, for 720x576 it is set as for the PAL TV
-standard, and for all others a 1:1 pixel aspect ratio is returned.
-
-An HDMI output has a valid EDID which can be obtained through VIDIOC_G_EDID.
-
-
-Section 4: VBI Capture
-----------------------
-
-There are three types of VBI capture devices: those that only support raw
-(undecoded) VBI, those that only support sliced (decoded) VBI and those that
-support both. This is determined by the node_types module option. In all
-cases the driver will generate valid VBI data: for 60 Hz standards it will
-generate Closed Caption and XDS data. The closed caption stream will
-alternate between "Hello world!" and "Closed captions test" every second.
-The XDS stream will give the current time once a minute. For 50 Hz standards
-it will generate the Wide Screen Signal which is based on the actual Video
-Aspect Ratio control setting and teletext pages 100-159, one page per frame.
-
-The VBI device will only work for the S-Video and TV inputs, it will give
-back an error if the current input is a webcam or HDMI.
-
-
-Section 5: VBI Output
----------------------
-
-There are three types of VBI output devices: those that only support raw
-(undecoded) VBI, those that only support sliced (decoded) VBI and those that
-support both. This is determined by the node_types module option.
-
-The sliced VBI output supports the Wide Screen Signal and the teletext signal
-for 50 Hz standards and Closed Captioning + XDS for 60 Hz standards.
-
-The VBI device will only work for the S-Video output, it will give
-back an error if the current output is HDMI.
-
-
-Section 6: Radio Receiver
--------------------------
-
-The radio receiver emulates an FM/AM/SW receiver. The FM band also supports RDS.
-The frequency ranges are:
-
-	FM: 64 MHz - 108 MHz
-	AM: 520 kHz - 1710 kHz
-	SW: 2300 kHz - 26.1 MHz
-
-Valid channels are emulated every 1 MHz for FM and every 100 kHz for AM and SW.
-The signal strength decreases the further the frequency is from the valid
-frequency until it becomes 0% at +/- 50 kHz (FM) or 5 kHz (AM/SW) from the
-ideal frequency. The initial frequency when the driver is loaded is set to
-95 MHz.
-
-The FM receiver supports RDS as well, both using 'Block I/O' and 'Controls'
-modes. In the 'Controls' mode the RDS information is stored in read-only
-controls. These controls are updated every time the frequency is changed,
-or when the tuner status is requested. The Block I/O method uses the read()
-interface to pass the RDS blocks on to the application for decoding.
-
-The RDS signal is 'detected' for +/- 12.5 kHz around the channel frequency,
-and the further the frequency is away from the valid frequency the more RDS
-errors are randomly introduced into the block I/O stream, up to 50% of all
-blocks if you are +/- 12.5 kHz from the channel frequency. All four errors
-can occur in equal proportions: blocks marked 'CORRECTED', blocks marked
-'ERROR', blocks marked 'INVALID' and dropped blocks.
-
-The generated RDS stream contains all the standard fields contained in a
-0B group, and also radio text and the current time.
-
-The receiver supports HW frequency seek, either in Bounded mode, Wrap Around
-mode or both, which is configurable with the "Radio HW Seek Mode" control.
-
-
-Section 7: Radio Transmitter
-----------------------------
-
-The radio transmitter emulates an FM/AM/SW transmitter. The FM band also supports RDS.
-The frequency ranges are:
-
-	FM: 64 MHz - 108 MHz
-	AM: 520 kHz - 1710 kHz
-	SW: 2300 kHz - 26.1 MHz
-
-The initial frequency when the driver is loaded is 95.5 MHz.
-
-The FM transmitter supports RDS as well, both using 'Block I/O' and 'Controls'
-modes. In the 'Controls' mode the transmitted RDS information is configured
-using controls, and in 'Block I/O' mode the blocks are passed to the driver
-using write().
-
-
-Section 8: Software Defined Radio Receiver
-------------------------------------------
-
-The SDR receiver has three frequency bands for the ADC tuner:
-
-	- 300 kHz
-	- 900 kHz - 2800 kHz
-	- 3200 kHz
-
-The RF tuner supports 50 MHz - 2000 MHz.
-
-The generated data contains the In-phase and Quadrature components of a
-1 kHz tone that has an amplitude of sqrt(2).
-
-
-Section 9: Controls
--------------------
-
-Different devices support different controls. The sections below will describe
-each control and which devices support them.
-
-
-Section 9.1: User Controls - Test Controls
-------------------------------------------
-
-The Button, Boolean, Integer 32 Bits, Integer 64 Bits, Menu, String, Bitmask and
-Integer Menu are controls that represent all possible control types. The Menu
-control and the Integer Menu control both have 'holes' in their menu list,
-meaning that one or more menu items return EINVAL when VIDIOC_QUERYMENU is called.
-Both menu controls also have a non-zero minimum control value.  These features
-allow you to check if your application can handle such things correctly.
-These controls are supported for every device type.
-
-
-Section 9.2: User Controls - Video Capture
-------------------------------------------
-
-The following controls are specific to video capture.
-
-The Brightness, Contrast, Saturation and Hue controls actually work and are
-standard. There is one special feature with the Brightness control: each
-video input has its own brightness value, so changing input will restore
-the brightness for that input. In addition, each video input uses a different
-brightness range (minimum and maximum control values). Switching inputs will
-cause a control event to be sent with the V4L2_EVENT_CTRL_CH_RANGE flag set.
-This allows you to test controls that can change their range.
-
-The 'Gain, Automatic' and Gain controls can be used to test volatile controls:
-if 'Gain, Automatic' is set, then the Gain control is volatile and changes
-constantly. If 'Gain, Automatic' is cleared, then the Gain control is a normal
-control.
-
-The 'Horizontal Flip' and 'Vertical Flip' controls can be used to flip the
-image. These combine with the 'Sensor Flipped Horizontally/Vertically' Vivid
-controls.
-
-The 'Alpha Component' control can be used to set the alpha component for
-formats containing an alpha channel.
-
-
-Section 9.3: User Controls - Audio
-----------------------------------
-
-The following controls are specific to video capture and output and radio
-receivers and transmitters.
-
-The 'Volume' and 'Mute' audio controls are typical for such devices to
-control the volume and mute the audio. They don't actually do anything in
-the vivid driver.
-
-
-Section 9.4: Vivid Controls
----------------------------
-
-These vivid custom controls control the image generation, error injection, etc.
-
-
-Section 9.4.1: Test Pattern Controls
-------------------------------------
-
-The Test Pattern Controls are all specific to video capture.
-
-Test Pattern: selects which test pattern to use. Use the CSC Colorbar for
-	testing colorspace conversions: the colors used in that test pattern
-	map to valid colors in all colorspaces. The colorspace conversion
-	is disabled for the other test patterns.
-
-OSD Text Mode: selects whether the text superimposed on the
-	test pattern should be shown, and if so, whether only counters should
-	be displayed or the full text.
-
-Horizontal Movement: selects whether the test pattern should
-	move to the left or right and at what speed.
-
-Vertical Movement: does the same for the vertical direction.
-
-Show Border: show a two-pixel wide border at the edge of the actual image,
-	excluding letter or pillarboxing.
-
-Show Square: show a square in the middle of the image. If the image is
-	displayed with the correct pixel and image aspect ratio corrections,
-	then the width and height of the square on the monitor should be
-	the same.
-
-Insert SAV Code in Image: adds a SAV (Start of Active Video) code to the image.
-	This can be used to check if such codes in the image are inadvertently
-	interpreted instead of being ignored.
-
-Insert EAV Code in Image: does the same for the EAV (End of Active Video) code.
-
-
-Section 9.4.2: Capture Feature Selection Controls
--------------------------------------------------
-
-These controls are all specific to video capture.
-
-Sensor Flipped Horizontally: the image is flipped horizontally and the
-	V4L2_IN_ST_HFLIP input status flag is set. This emulates the case where
-	a sensor is for example mounted upside down.
-
-Sensor Flipped Vertically: the image is flipped vertically and the
-	V4L2_IN_ST_VFLIP input status flag is set. This emulates the case where
-        a sensor is for example mounted upside down.
-
-Standard Aspect Ratio: selects if the image aspect ratio as used for the TV or
-	S-Video input should be 4x3, 16x9 or anamorphic widescreen. This may
-	introduce letterboxing.
-
-DV Timings Aspect Ratio: selects if the image aspect ratio as used for the HDMI
-	input should be the same as the source width and height ratio, or if
-	it should be 4x3 or 16x9. This may introduce letter or pillarboxing.
-
-Timestamp Source: selects when the timestamp for each buffer is taken.
-
-Colorspace: selects which colorspace should be used when generating the image.
-	This only applies if the CSC Colorbar test pattern is selected,
-	otherwise the test pattern will go through unconverted.
-	This behavior is also what you want, since a 75% Colorbar
-	should really have 75% signal intensity and should not be affected
-	by colorspace conversions.
-
-	Changing the colorspace will result in the V4L2_EVENT_SOURCE_CHANGE
-	to be sent since it emulates a detected colorspace change.
-
-Transfer Function: selects which colorspace transfer function should be used when
-	generating an image. This only applies if the CSC Colorbar test pattern is
-	selected, otherwise the test pattern will go through unconverted.
-        This behavior is also what you want, since a 75% Colorbar
-        should really have 75% signal intensity and should not be affected
-        by colorspace conversions.
-
-	Changing the transfer function will result in the V4L2_EVENT_SOURCE_CHANGE
-	to be sent since it emulates a detected colorspace change.
-
-Y'CbCr Encoding: selects which Y'CbCr encoding should be used when generating
-	a Y'CbCr image.	This only applies if the format is set to a Y'CbCr format
-	as opposed to an RGB format.
-
-	Changing the Y'CbCr encoding will result in the V4L2_EVENT_SOURCE_CHANGE
-	to be sent since it emulates a detected colorspace change.
-
-Quantization: selects which quantization should be used for the RGB or Y'CbCr
-	encoding when generating the test pattern.
-
-	Changing the quantization will result in the V4L2_EVENT_SOURCE_CHANGE
-	to be sent since it emulates a detected colorspace change.
-
-Limited RGB Range (16-235): selects if the RGB range of the HDMI source should
-	be limited or full range. This combines with the Digital Video 'Rx RGB
-	Quantization Range' control and can be used to test what happens if
-	a source provides you with the wrong quantization range information.
-	See the description of that control for more details.
-
-Apply Alpha To Red Only: apply the alpha channel as set by the 'Alpha Component'
-	user control to the red color of the test pattern only.
-
-Enable Capture Cropping: enables crop support. This control is only present if
-	the ccs_cap_mode module option is set to the default value of -1 and if
-	the no_error_inj module option is set to 0 (the default).
-
-Enable Capture Composing: enables composing support. This control is only
-	present if the ccs_cap_mode module option is set to the default value of
-	-1 and if the no_error_inj module option is set to 0 (the default).
-
-Enable Capture Scaler: enables support for a scaler (maximum 4 times upscaling
-	and downscaling). This control is only present if the ccs_cap_mode
-	module option is set to the default value of -1 and if the no_error_inj
-	module option is set to 0 (the default).
-
-Maximum EDID Blocks: determines how many EDID blocks the driver supports.
-	Note that the vivid driver does not actually interpret new EDID
-	data, it just stores it. It allows for up to 256 EDID blocks
-	which is the maximum supported by the standard.
-
-Fill Percentage of Frame: can be used to draw only the top X percent
-	of the image. Since each frame has to be drawn by the driver, this
-	demands a lot of the CPU. For large resolutions this becomes
-	problematic. By drawing only part of the image this CPU load can
-	be reduced.
-
-
-Section 9.4.3: Output Feature Selection Controls
-------------------------------------------------
-
-These controls are all specific to video output.
-
-Enable Output Cropping: enables crop support. This control is only present if
-	the ccs_out_mode module option is set to the default value of -1 and if
-	the no_error_inj module option is set to 0 (the default).
-
-Enable Output Composing: enables composing support. This control is only
-	present if the ccs_out_mode module option is set to the default value of
-	-1 and if the no_error_inj module option is set to 0 (the default).
-
-Enable Output Scaler: enables support for a scaler (maximum 4 times upscaling
-	and downscaling). This control is only present if the ccs_out_mode
-	module option is set to the default value of -1 and if the no_error_inj
-	module option is set to 0 (the default).
-
-
-Section 9.4.4: Error Injection Controls
----------------------------------------
-
-The following two controls are only valid for video and vbi capture.
-
-Standard Signal Mode: selects the behavior of VIDIOC_QUERYSTD: what should
-	it return?
-
-	Changing this control will result in the V4L2_EVENT_SOURCE_CHANGE
-	to be sent since it emulates a changed input condition (e.g. a cable
-	was plugged in or out).
-
-Standard: selects the standard that VIDIOC_QUERYSTD should return if the
-	previous control is set to "Selected Standard".
-
-	Changing this control will result in the V4L2_EVENT_SOURCE_CHANGE
-	to be sent since it emulates a changed input standard.
-
-
-The following two controls are only valid for video capture.
-
-DV Timings Signal Mode: selects the behavior of VIDIOC_QUERY_DV_TIMINGS: what
-	should it return?
-
-	Changing this control will result in the V4L2_EVENT_SOURCE_CHANGE
-	to be sent since it emulates a changed input condition (e.g. a cable
-	was plugged in or out).
-
-DV Timings: selects the timings the VIDIOC_QUERY_DV_TIMINGS should return
-	if the previous control is set to "Selected DV Timings".
-
-	Changing this control will result in the V4L2_EVENT_SOURCE_CHANGE
-	to be sent since it emulates changed input timings.
-
-
-The following controls are only present if the no_error_inj module option
-is set to 0 (the default). These controls are valid for video and vbi
-capture and output streams and for the SDR capture device except for the
-Disconnect control which is valid for all devices.
-
-Wrap Sequence Number: test what happens when you wrap the sequence number in
-	struct v4l2_buffer around.
-
-Wrap Timestamp: test what happens when you wrap the timestamp in struct
-	v4l2_buffer around.
-
-Percentage of Dropped Buffers: sets the percentage of buffers that
-	are never returned by the driver (i.e., they are dropped).
-
-Disconnect: emulates a USB disconnect. The device will act as if it has
-	been disconnected. Only after all open filehandles to the device
-	node have been closed will the device become 'connected' again.
-
-Inject V4L2_BUF_FLAG_ERROR: when pressed, the next frame returned by
-	the driver will have the error flag set (i.e. the frame is marked
-	corrupt).
-
-Inject VIDIOC_REQBUFS Error: when pressed, the next REQBUFS or CREATE_BUFS
-	ioctl call will fail with an error. To be precise: the videobuf2
-	queue_setup() op will return -EINVAL.
-
-Inject VIDIOC_QBUF Error: when pressed, the next VIDIOC_QBUF or
-	VIDIOC_PREPARE_BUFFER ioctl call will fail with an error. To be
-	precise: the videobuf2 buf_prepare() op will return -EINVAL.
-
-Inject VIDIOC_STREAMON Error: when pressed, the next VIDIOC_STREAMON ioctl
-	call will fail with an error. To be precise: the videobuf2
-	start_streaming() op will return -EINVAL.
-
-Inject Fatal Streaming Error: when pressed, the streaming core will be
-	marked as having suffered a fatal error, the only way to recover
-	from that is to stop streaming. To be precise: the videobuf2
-	vb2_queue_error() function is called.
-
-
-Section 9.4.5: VBI Raw Capture Controls
----------------------------------------
-
-Interlaced VBI Format: if set, then the raw VBI data will be interlaced instead
-	of providing it grouped by field.
-
-
-Section 9.5: Digital Video Controls
------------------------------------
-
-Rx RGB Quantization Range: sets the RGB quantization detection of the HDMI
-	input. This combines with the Vivid 'Limited RGB Range (16-235)'
-	control and can be used to test what happens if a source provides
-	you with the wrong quantization range information. This can be tested
-	by selecting an HDMI input, setting this control to Full or Limited
-	range and selecting the opposite in the 'Limited RGB Range (16-235)'
-	control. The effect is easy to see if the 'Gray Ramp' test pattern
-	is selected.
-
-Tx RGB Quantization Range: sets the RGB quantization detection of the HDMI
-	output. It is currently not used for anything in vivid, but most HDMI
-	transmitters would typically have this control.
-
-Transmit Mode: sets the transmit mode of the HDMI output to HDMI or DVI-D. This
-	affects the reported colorspace since DVI_D outputs will always use
-	sRGB.
-
-
-Section 9.6: FM Radio Receiver Controls
----------------------------------------
-
-RDS Reception: set if the RDS receiver should be enabled.
-
-RDS Program Type:
-RDS PS Name:
-RDS Radio Text:
-RDS Traffic Announcement:
-RDS Traffic Program:
-RDS Music: these are all read-only controls. If RDS Rx I/O Mode is set to
-	"Block I/O", then they are inactive as well. If RDS Rx I/O Mode is set
-	to "Controls", then these controls report the received RDS data. Note
-	that the vivid implementation of this is pretty basic: they are only
-	updated when you set a new frequency or when you get the tuner status
-	(VIDIOC_G_TUNER).
-
-Radio HW Seek Mode: can be one of "Bounded", "Wrap Around" or "Both". This
-	determines if VIDIOC_S_HW_FREQ_SEEK will be bounded by the frequency
-	range or wrap-around or if it is selectable by the user.
-
-Radio Programmable HW Seek: if set, then the user can provide the lower and
-	upper bound of the HW Seek. Otherwise the frequency range boundaries
-	will be used.
-
-Generate RBDS Instead of RDS: if set, then generate RBDS (the US variant of
-	RDS) data instead of RDS (European-style RDS). This affects only the
-	PICODE and PTY codes.

-
-Section 10: Video, VBI and RDS Looping
---------------------------------------
-
-The vivid driver supports looping of video output to video input, VBI output
-to VBI input and RDS output to RDS input. For video/VBI looping this emulates
-as if a cable was hooked up between the output and input connector. So video
-and VBI looping is only supported between S-Video and HDMI inputs and outputs.
-VBI is only valid for S-Video as it makes no sense for HDMI.
-
-Since radio is wireless this looping always happens if the radio receiver
-frequency is close to the radio transmitter frequency. In that case the radio
-transmitter will 'override' the emulated radio stations.
-
-Looping is currently supported only between devices created by the same
-vivid driver instance.
-
-
-Section 10.1: Video and Sliced VBI looping
-------------------------------------------
-
-The way to enable video/VBI looping is currently fairly crude. A 'Loop Video'
-control is available in the "Vivid" control class of the video
-capture and VBI capture devices. When checked the video looping will be enabled.
-Once enabled any video S-Video or HDMI input will show a static test pattern
-until the video output has started. At that time the video output will be
-looped to the video input provided that:
-
-- the input type matches the output type. So the HDMI input cannot receive
-  video from the S-Video output.
-
-- the video resolution of the video input must match that of the video output.
-  So it is not possible to loop a 50 Hz (720x576) S-Video output to a 60 Hz
-  (720x480) S-Video input, or a 720p60 HDMI output to a 1080p30 input.
-
-- the pixel formats must be identical on both sides. Otherwise the driver would
-  have to do pixel format conversion as well, and that's taking things too far.
-
-- the field settings must be identical on both sides. Same reason as above:
-  requiring the driver to convert from one field format to another complicated
-  matters too much. This also prohibits capturing with 'Field Top' or 'Field
-  Bottom' when the output video is set to 'Field Alternate'. This combination,
-  while legal, became too complicated to support. Both sides have to be 'Field
-  Alternate' for this to work. Also note that for this specific case the
-  sequence and field counting in struct v4l2_buffer on the capture side may not
-  be 100% accurate.
-
-- field settings V4L2_FIELD_SEQ_TB/BT are not supported. While it is possible to
-  implement this, it would mean a lot of work to get this right. Since these
-  field values are rarely used the decision was made not to implement this for
-  now.
-
-- on the input side the "Standard Signal Mode" for the S-Video input or the
-  "DV Timings Signal Mode" for the HDMI input should be configured so that a
-  valid signal is passed to the video input.
-
-The framerates do not have to match, although this might change in the future.
-
-By default you will see the OSD text superimposed on top of the looped video.
-This can be turned off by changing the "OSD Text Mode" control of the video
-capture device.
-
-For VBI looping to work all of the above must be valid and in addition the vbi
-output must be configured for sliced VBI. The VBI capture side can be configured
-for either raw or sliced VBI. Note that at the moment only CC/XDS (60 Hz formats)
-and WSS (50 Hz formats) VBI data is looped. Teletext VBI data is not looped.
-
-
-Section 10.2: Radio & RDS Looping
----------------------------------
-
-As mentioned in section 6 the radio receiver emulates stations are regular
-frequency intervals. Depending on the frequency of the radio receiver a
-signal strength value is calculated (this is returned by VIDIOC_G_TUNER).
-However, it will also look at the frequency set by the radio transmitter and
-if that results in a higher signal strength than the settings of the radio
-transmitter will be used as if it was a valid station. This also includes
-the RDS data (if any) that the transmitter 'transmits'. This is received
-faithfully on the receiver side. Note that when the driver is loaded the
-frequencies of the radio receiver and transmitter are not identical, so
-initially no looping takes place.
-
-
-Section 11: Cropping, Composing, Scaling
-----------------------------------------
-
-This driver supports cropping, composing and scaling in any combination. Normally
-which features are supported can be selected through the Vivid controls,
-but it is also possible to hardcode it when the module is loaded through the
-ccs_cap_mode and ccs_out_mode module options. See section 1 on the details of
-these module options.
-
-This allows you to test your application for all these variations.
-
-Note that the webcam input never supports cropping, composing or scaling. That
-only applies to the TV/S-Video/HDMI inputs and outputs. The reason is that
-webcams, including this virtual implementation, normally use
-VIDIOC_ENUM_FRAMESIZES to list a set of discrete framesizes that it supports.
-And that does not combine with cropping, composing or scaling. This is
-primarily a limitation of the V4L2 API which is carefully reproduced here.
-
-The minimum and maximum resolutions that the scaler can achieve are 16x16 and
-(4096 * 4) x (2160 x 4), but it can only scale up or down by a factor of 4 or
-less. So for a source resolution of 1280x720 the minimum the scaler can do is
-320x180 and the maximum is 5120x2880. You can play around with this using the
-qv4l2 test tool and you will see these dependencies.
-
-This driver also supports larger 'bytesperline' settings, something that
-VIDIOC_S_FMT allows but that few drivers implement.
-
-The scaler is a simple scaler that uses the Coarse Bresenham algorithm. It's
-designed for speed and simplicity, not quality.
-
-If the combination of crop, compose and scaling allows it, then it is possible
-to change crop and compose rectangles on the fly.
-
-
-Section 12: Formats
--------------------
-
-The driver supports all the regular packed and planar 4:4:4, 4:2:2 and 4:2:0
-YUYV formats, 8, 16, 24 and 32 RGB packed formats and various multiplanar
-formats.
-
-The alpha component can be set through the 'Alpha Component' User control
-for those formats that support it. If the 'Apply Alpha To Red Only' control
-is set, then the alpha component is only used for the color red and set to
-0 otherwise.
-
-The driver has to be configured to support the multiplanar formats. By default
-the driver instances are single-planar. This can be changed by setting the
-multiplanar module option, see section 1 for more details on that option.
-
-If the driver instance is using the multiplanar formats/API, then the first
-single planar format (YUYV) and the multiplanar NV16M and NV61M formats the
-will have a plane that has a non-zero data_offset of 128 bytes. It is rare for
-data_offset to be non-zero, so this is a useful feature for testing applications.
-
-Video output will also honor any data_offset that the application set.
-
-
-Section 13: Capture Overlay
----------------------------
-
-Note: capture overlay support is implemented primarily to test the existing
-V4L2 capture overlay API. In practice few if any GPUs support such overlays
-anymore, and neither are they generally needed anymore since modern hardware
-is so much more capable. By setting flag 0x10000 in the node_types module
-option the vivid driver will create a simple framebuffer device that can be
-used for testing this API. Whether this API should be used for new drivers is
-questionable.
-
-This driver has support for a destructive capture overlay with bitmap clipping
-and list clipping (up to 16 rectangles) capabilities. Overlays are not
-supported for multiplanar formats. It also honors the struct v4l2_window field
-setting: if it is set to FIELD_TOP or FIELD_BOTTOM and the capture setting is
-FIELD_ALTERNATE, then only the top or bottom fields will be copied to the overlay.
-
-The overlay only works if you are also capturing at that same time. This is a
-vivid limitation since it copies from a buffer to the overlay instead of
-filling the overlay directly. And if you are not capturing, then no buffers
-are available to fill.
-
-In addition, the pixelformat of the capture format and that of the framebuffer
-must be the same for the overlay to work. Otherwise VIDIOC_OVERLAY will return
-an error.
-
-In order to really see what it going on you will need to create two vivid
-instances: the first with a framebuffer enabled. You configure the capture
-overlay of the second instance to use the framebuffer of the first, then
-you start capturing in the second instance. For the first instance you setup
-the output overlay for the video output, turn on video looping and capture
-to see the blended framebuffer overlay that's being written to by the second
-instance. This setup would require the following commands:
-
-	$ sudo modprobe vivid n_devs=2 node_types=0x10101,0x1
-	$ v4l2-ctl -d1 --find-fb
-	/dev/fb1 is the framebuffer associated with base address 0x12800000
-	$ sudo v4l2-ctl -d2 --set-fbuf fb=1
-	$ v4l2-ctl -d1 --set-fbuf fb=1
-	$ v4l2-ctl -d0 --set-fmt-video=pixelformat='AR15'
-	$ v4l2-ctl -d1 --set-fmt-video-out=pixelformat='AR15'
-	$ v4l2-ctl -d2 --set-fmt-video=pixelformat='AR15'
-	$ v4l2-ctl -d0 -i2
-	$ v4l2-ctl -d2 -i2
-	$ v4l2-ctl -d2 -c horizontal_movement=4
-	$ v4l2-ctl -d1 --overlay=1
-	$ v4l2-ctl -d1 -c loop_video=1
-	$ v4l2-ctl -d2 --stream-mmap --overlay=1
-
-And from another console:
-
-	$ v4l2-ctl -d1 --stream-out-mmap
-
-And yet another console:
-
-	$ qv4l2
-
-and start streaming.
-
-As you can see, this is not for the faint of heart...
-
-
-Section 14: Output Overlay
---------------------------
-
-Note: output overlays are primarily implemented in order to test the existing
-V4L2 output overlay API. Whether this API should be used for new drivers is
-questionable.
-
-This driver has support for an output overlay and is capable of:
-
-	- bitmap clipping,
-	- list clipping (up to 16 rectangles)
-	- chromakey
-	- source chromakey
-	- global alpha
-	- local alpha
-	- local inverse alpha
-
-Output overlays are not supported for multiplanar formats. In addition, the
-pixelformat of the capture format and that of the framebuffer must be the
-same for the overlay to work. Otherwise VIDIOC_OVERLAY will return an error.
-
-Output overlays only work if the driver has been configured to create a
-framebuffer by setting flag 0x10000 in the node_types module option. The
-created framebuffer has a size of 720x576 and supports ARGB 1:5:5:5 and
-RGB 5:6:5.
-
-In order to see the effects of the various clipping, chromakeying or alpha
-processing capabilities you need to turn on video looping and see the results
-on the capture side. The use of the clipping, chromakeying or alpha processing
-capabilities will slow down the video loop considerably as a lot of checks have
-to be done per pixel.
-
-
-Section 15: Some Future Improvements
-------------------------------------
-
-Just as a reminder and in no particular order:
-
-- Add a virtual alsa driver to test audio
-- Add virtual sub-devices and media controller support
-- Some support for testing compressed video
-- Add support to loop raw VBI output to raw VBI input
-- Add support to loop teletext sliced VBI output to VBI input
-- Fix sequence/field numbering when looping of video with alternate fields
-- Add support for V4L2_CID_BG_COLOR for video outputs
-- Add ARGB888 overlay support: better testing of the alpha channel
-- Add custom DV timings support
-- Add support for V4L2_DV_FL_REDUCED_FPS
-- Improve pixel aspect support in the tpg code by passing a real v4l2_fract
-- Use per-queue locks and/or per-device locks to improve throughput
-- Add support to loop from a specific output to a specific input across
-  vivid instances
-- The SDR radio should use the same 'frequencies' for stations as the normal
-  radio receiver, and give back noise if the frequency doesn't match up with
-  a station frequency
-- Make a thread for the RDS generation, that would help in particular for the
-  "Controls" RDS Rx I/O Mode as the read-only RDS controls could be updated
-  in real-time.

-Zoran 364xx based USB webcam module version 0.72
-site: http://royale.zerezo.com/zr364xx/
-mail: royale@zerezo.com
-
-introduction:
-This brings support under Linux for the Aiptek PocketDV 3300 in webcam mode.
-If you just want to get on your PC the pictures and movies on the camera, you should use the usb-storage module instead.
-The driver works with several other cameras in webcam mode (see the list below).
-Maybe this code can work for other JPEG/USB cams based on the Coach chips from Zoran?
-Possible chipsets are : ZR36430 (ZR36430BGC) and maybe ZR36431, ZR36440, ZR36442...
-You can try the experience changing the vendor/product ID values (look at the source code).
-You can get these values by looking at /var/log/messages when you plug your camera, or by typing : cat /proc/bus/usb/devices.
-If you manage to use your cam with this code, you can send me a mail (royale@zerezo.com) with the name of your cam and a patch if needed.
-This is a beta release of the driver.
-Since version 0.70, this driver is only compatible with V4L2 API and 2.6.x kernels.
-If you need V4L1 or 2.4x kernels support, please use an older version, but the code is not maintained anymore.
-Good luck!
-
-install:
-In order to use this driver, you must compile it with your kernel.
-Location: Device Drivers -> Multimedia devices -> Video For Linux -> Video Capture Adapters -> V4L USB devices
-
-usage:
-modprobe zr364xx debug=X mode=Y
- - debug      : set to 1 to enable verbose debug messages
- - mode       : 0 = 320x240, 1 = 160x120, 2 = 640x480
-You can then use the camera with V4L2 compatible applications, for example Ekiga.
-To capture a single image, try this: dd if=/dev/video0 of=test.jpg bs=1M count=1

-#	STRUCT job_aes2
-#	RES_Q	.plaintext,	1
-#	RES_Q	.ciphertext,	1
-#	RES_DQ	.IV,		1
-#	RES_B	.nested,	_JOB_AES_SIZE, _JOB_AES_ALIGN
-#	RES_U	.union,		size1, align1, \
-#				size2, align2, \
-#				...
-#	ENDSTRUCT
-#	# Following only needed if nesting
-#	%assign job_aes2_size	_FIELD_OFFSET
-#	%assign job_aes2_align	_STRUCT_ALIGN
-#
-# RES_* macros take a name, a count and an optional alignment.
-# The count in in terms of the base size of the macro, and the
-# default alignment is the base size.
-# The macros are:
-# Macro    Base size
-# RES_B	    1
-# RES_W	    2
-# RES_D     4
-# RES_Q     8
-# RES_DQ   16
-# RES_Y    32
-# RES_Z    64
-#
-# RES_U defines a union. It's arguments are a name and two or more
-# pairs of "size, alignment"
-#
-# The two assigns are only needed if this structure is being nested
-# within another. Even if the assigns are not done, one can still use
-# STRUCT_NAME_size as the size of the structure.
-#
-# Note that for nesting, you still need to assign to STRUCT_NAME_size.
-#
-# The differences between this and using "struc" directly are that each
-# type is implicitly aligned to its natural length (although this can be
-# over-ridden with an explicit third parameter), and that the structure
-# is padded at the end to its overall alignment.

- *	based on Paul Gortmaker's rtc.c device and

- *
- *	This driver allows use of the real time clock (built into

- *	interface supporting various ioctl() and also the /proc/driver/rtc
- *	pseudo-file for status information.
- *
- *	The ioctls can be used to set the interrupt behaviour where
- *	supported.
- *
- *	The /dev/rtc interface will block on reads until an interrupt
- *	has been received. If a RTC interrupt has already happened,
- *	it will output an unsigned long and then block. The output value
- *	contains the interrupt status in the low byte and the number of
- *	interrupts since the last read in the remaining high bytes. The

- * Based on the Freescale DMA driver.
- *
- * Description:
- * The AXI Video Direct Memory Access (AXI VDMA) core is a soft Xilinx IP
- * core that provides high-bandwidth direct memory access between memory
- * and AXI4-Stream type video target peripherals. The core provides efficient
- * two dimensional DMA operations with independent asynchronous read (S2MM)
- * and write (MM2S) channel operation. It can be configured to have either
- * one channel or two channels. If configured as two channels, one is to
- * transmit to the video device (MM2S) and another is to receive from the
- * video device (S2MM). Initialization, status, interrupt and management
- * registers are accessed through an AXI4-Lite slave interface.
- *
- * The AXI Direct Memory Access (AXI DMA) core is a soft Xilinx IP core that
- * provides high-bandwidth one dimensional direct memory access between memory
- * and AXI4-Stream target peripherals. It supports one receive and one
- * transmit channel, both of them optional at synthesis time.
- *
- * The AXI CDMA, is a soft IP, which provides high-bandwidth Direct Memory
- * Access (DMA) between a memory-mapped source address and a memory-mapped
- * destination address.
- *

- * Loadable modules and other fixes by AK, 1998
- *
- * Maximum number of loop devices now dynamic via max_loop module parameter.
- * Russell Kroll <rkroll@exploits.org> 19990701
- *
- * Maximum number of loop devices when compiled-in now selectable by passing
- * max_loop=<1-255> to the kernel on boot.
- * Erik I. Bols?, <eriki@himolde.no>, Oct 31, 1999
- *
- * Completely rewrite request handling to be make_request_fn style and
- * non blocking, pushing work to a helper thread. Lots of fixes from
- * Al Viro too.
- * Jens Axboe <axboe@suse.de>, Nov 2000
- *
- * Support up to 256 loop devices
- * Heinz Mauelshagen <mge@sistina.com>, Feb 2002
- *
- * Support for falling back on the write file operation when the address space
- * operations prepare_write and/or commit_write are not available on the
- * backing filesystem.
- * Anton Altaparmakov, 16 Feb 2005
- *
- * Still To Fix:
- * - Advisory locking is ignored here.
- * - Should use an own CAP_* category instead of CAP_SYS_ADMIN
- *

-	 * 1. Define a new operation in cl_object_operations{}, says clo_depth,
-	 *    which measures how many layers for this lustre object. Generally
-	 *    speaking, the depth would be 2, one for llite, and one for lovsub.
-	 *    However, for SNS, there will be more since we need additional page
-	 *    to store parity;
-	 * 2. Reserve the # of (page_count * depth) cl_pages from the reserved
-	 *    pool. Afterwards, the clio would allocate the pages from reserved
-	 *    pool, this guarantees we needn't allocate the cl_pages from
-	 *    generic cl_page slab cache.
-	 *    Of course, if there is NOT enough pages in the pool, we might
-	 *    be asked to write less pages once, this purely depends on
-	 *    implementation. Anyway, we should be careful to avoid deadlocking.

-Driver general quality is not good enough for mainline. Also, other
-device drivers (USB-bridge, tuner) needed for Astrometa receiver in
-question could need some changes. However, if that driver is mainlined
-due to some other device than Astrometa, unrelated TODOs could be
-skipped. In that case rtl28xxu driver needs module parameter to prevent
-driver loading.
-
-Required TODOs:
-* missing lock flags
-* I2C errors
-* tuner sensitivity
-
-*Do not* send any patch fixing checkpatch.pl issues. Currently it passes
-checkpatch.pl tests. I don't want waste my time to review this kind of
-trivial stuff. *Do not* add missing register I/O error checks. Those are
-missing for the reason it is much easier to compare I2C data sniffs when
-there is less lines. Those error checks are about the last thing to be added.
-
-Patches should be submitted to:
-linux-media@vger.kernel.org and Antti Palosaari <crope@iki.fi>

- * Copyright (C) 2006-2015 Nigel Cunningham (nigel at nigelcunningham com au)
- *
- * This file is released under the GPLv2.
- *
- * This file contains routines for cluster hibernation support.
- *
- * Based on ip autoconfiguration code in net/ipv4/ipconfig.c.
- *
- * How does it work?
- *
- * There is no 'master' node that tells everyone else what to do. All nodes
- * send messages to the broadcast address/port, maintain a list of peers
- * and figure out when to progress to the next step in hibernating or resuming.
- * This makes us more fault tolerant when it comes to nodes coming and going
- * (which may be more of an issue if we're hibernating when power supplies
- * are being unreliable).
- *
- * At boot time, we start a ktuxonice thread that handles communication with
- * other nodes. This node maintains a state machine that controls our progress
- * through hibernating and resuming, keeping us in step with other nodes. Nodes
- * are identified by their hw address.
- *
- * On startup, the node sends CLUSTER_PING on the configured interface's
- * broadcast address, port $toi_cluster_port (see below) and begins to listen
- * for other broadcast messages. CLUSTER_PING messages are repeated at
- * intervals of 5 minutes, with a random offset to spread traffic out.
- *
- * A hibernation cycle is initiated from any node via
- *
- * echo > /sys/power/tuxonice/do_hibernate
- *
- * and (possibily) the hibernate script. At each step of the process, the node
- * completes its work, and waits for all other nodes to signal completion of
- * their work (or timeout) before progressing to the next step.
- *
- * Request/state  Action before reply        Possible reply        Next state
- * HIBERNATE          capable, pre-script        HIBERNATE|ACK        NODE_PREP

- * Other messages:
- *
- * - PING: Request for all other live nodes to send a PONG. Used at startup to
- *   announce presence, when a node is suspected dead and periodically, in case
- *   segments of the network are [un]plugged.
- *
- * - PONG: Response to a PING.
- *
- * - ABORT: Request to cancel writing an image.
- *
- * - BYE: Notification that this node is shutting down.
- *
- * Note 1: Repeated at 3s intervals until we continue to boot/resume, so that
- * nodes which are slower to start up can get state synchronised. If a node
- * starting up sees other nodes sending RESUME_PREP or IMAGE_READ, it may send
- * ACK_IMAGE and they will wait for it to catch up. If it sees ACK_READ, it
- * must invalidate its image (if any) and boot normally.
- *
- * Note 2: May occur when one node lost power or powered off while others
- * hibernated. This node waits for others to complete resuming (ACK_READ)
- * before completing its boot, so that it appears as a fail node restarting.
- *
- * If any node has an image, then it also has a list of nodes that hibernated
- * in synchronisation with it. The node will wait for other nodes to appear
- * or timeout before beginning its restoration.
- *
- * If a node has no image, it needs to wait, in case other nodes which do have
- * an image are going to resume, but are taking longer to announce their
- * presence. For this reason, the user can specify a timeout value and a number
- * of nodes detected before we just continue. (We might want to assume in a
- * cluster of, say, 15 nodes, if 8 others have booted without finding an image,
- * the remaining nodes will too. This might help in situations where some nodes
- * are much slower to boot, or more subject to hardware failures or such like).

-/** \mainpage TuxOnIce.
- *
- * TuxOnIce provides support for saving and restoring an image of
- * system memory to an arbitrary storage device, either on the local computer,
- * or across some network. The support is entirely OS based, so TuxOnIce
- * works without requiring BIOS, APM or ACPI support. The vast majority of the
- * code is also architecture independant, so it should be very easy to port
- * the code to new architectures. TuxOnIce includes support for SMP, 4G HighMem
- * and preemption. Initramfses and initrds are also supported.
- *
- * TuxOnIce uses a modular design, in which the method of storing the image is
- * completely abstracted from the core code, as are transformations on the data
- * such as compression and/or encryption (multiple 'modules' can be used to
- * provide arbitrary combinations of functionality). The user interface is also
- * modular, so that arbitrarily simple or complex interfaces can be used to
- * provide anything from debugging information through to eye candy.

- * \section Credits
- *
- * Nigel would like to thank the following people for their work:
- *
- * Bernard Blackham <bernard@blackham.com.au><BR>
- * Web page & Wiki administration, some coding. A person without whom
- * TuxOnIce would not be where it is.
- *
- * Michael Frank <mhf@linuxmail.org><BR>
- * Extensive testing and help with improving stability. I was constantly
- * amazed by the quality and quantity of Michael's help.
- *
- * Pavel Machek <pavel@ucw.cz><BR>
- * Modifications, defectiveness pointing, being with Gabor at the very
- * beginning, suspend to swap space, stop all tasks. Port to 2.4.18-ac and
- * 2.5.17. Even though Pavel and I disagree on the direction suspend to
- * disk should take, I appreciate the valuable work he did in helping Gabor
- * get the concept working.
- *
- * ..and of course the myriads of TuxOnIce users who have helped diagnose
- * and fix bugs, made suggestions on how to improve the code, proofread
- * documentation, and donated time and money.
- *
- * Thanks also to corporate sponsors:
- *
- * <B>Redhat.</B>Sometime employer from May 2006 (my fault, not Redhat's!).
- *
- * <B>Cyclades.com.</B> Nigel's employers from Dec 2004 until May 2006, who
- * allowed him to work on TuxOnIce and PM related issues on company time.
- *
- * <B>LinuxFund.org.</B> Sponsored Nigel's work on TuxOnIce for four months Oct
- * 2003 to Jan 2004.
- *
- * <B>LAC Linux.</B> Donated P4 hardware that enabled development and ongoing
- * maintenance of SMP and Highmem support.
- *
- * <B>OSDL.</B> Provided access to various hardware configurations, make
- * occasional small donations to the project.

- * GICv3 distributor and redistributor emulation
- *
- * GICv3 emulation is currently only supported on a GICv3 host (because
- * we rely on the hardware's CPU interface virtualization support), but
- * supports both hardware with or without the optional GICv2 backwards
- * compatibility features.
- *
- * Limitations of the emulation:
- * (RAZ/WI: read as zero, write ignore, RAO/WI: read as one, write ignore)
- * - We do not support LPIs (yet). TYPER.LPIS is reported as 0 and is RAZ/WI.
- * - We do not support the message based interrupts (MBIs) triggered by
- *   writes to the GICD_{SET,CLR}SPI_* registers. TYPER.MBIS is reported as 0.
- * - We do not support the (optional) backwards compatibility feature.
- *   GICD_CTLR.ARE resets to 1 and is RAO/WI. If the _host_ GIC supports
- *   the compatiblity feature, you can use a GICv2 in the guest, though.
- * - We only support a single security state. GICD_CTLR.DS is 1 and is RAO/WI.
- * - Priorities are not emulated (same as the GICv2 emulation). Linux
- *   as a guest is fine with this, because it does not use priorities.
- * - We only support Group1 interrupts. Again Linux uses only those.

-/*
- * How the whole thing works (courtesy of Christoffer Dall):
- *
- * - At any time, the dist->irq_pending_on_cpu is the oracle that knows if
- *   something is pending on the CPU interface.
- * - Interrupts that are pending on the distributor are stored on the
- *   vgic.irq_pending vgic bitmap (this bitmap is updated by both user land
- *   ioctls and guest mmio ops, and other in-kernel peripherals such as the
- *   arch. timers).
- * - Every time the bitmap changes, the irq_pending_on_cpu oracle is
- *   recalculated
- * - To calculate the oracle, we need info for each cpu from
- *   compute_pending_for_cpu, which considers:
- *   - PPI: dist->irq_pending & dist->irq_enable
- *   - SPI: dist->irq_pending & dist->irq_enable & dist->irq_spi_target
- *   - irq_spi_target is a 'formatted' version of the GICD_ITARGETSRn
- *     registers, stored on each vcpu. We only keep one bit of
- *     information per interrupt, making sure that only one vcpu can
- *     accept the interrupt.
- * - If any of the above state changes, we must recalculate the oracle.
- * - The same is true when injecting an interrupt, except that we only
- *   consider a single interrupt at a time. The irq_spi_cpu array
- *   contains the target CPU for each SPI.
- *
- * The handling of level interrupts adds some extra complexity. We
- * need to track when the interrupt has been EOIed, so we can sample
- * the 'line' again. This is achieved as such:
- *
- * - When a level interrupt is moved onto a vcpu, the corresponding
- *   bit in irq_queued is set. As long as this bit is set, the line
- *   will be ignored for further interrupts. The interrupt is injected
- *   into the vcpu with the GICH_LR_EOI bit set (generate a
- *   maintenance interrupt on EOI).
- * - When the interrupt is EOIed, the maintenance interrupt fires,
- *   and clears the corresponding bit in irq_queued. This allows the
- *   interrupt line to be sampled again.
- * - Note that level-triggered interrupts can also be set to pending from
- *   writes to GICD_ISPENDRn and lowering the external input line does not
- *   cause the interrupt to become inactive in such a situation.
- *   Conversely, writes to GICD_ICPENDRn do not cause the interrupt to become
- *   inactive as long as the external input line is held high.
- *
- *
- * Initialization rules: there are multiple stages to the vgic
- * initialization, both for the distributor and the CPU interfaces.
- *
- * Distributor:
- *
- * - kvm_vgic_early_init(): initialization of static data that doesn't
- *   depend on any sizing information or emulation type. No allocation
- *   is allowed there.
- *
- * - vgic_init(): allocation and initialization of the generic data
- *   structures that depend on sizing information (number of CPUs,
- *   number of interrupts). Also initializes the vcpu specific data
- *   structures. Can be executed lazily for GICv2.
- *   [to be renamed to kvm_vgic_init??]
- *
- * CPU Interface:
- *
- * - kvm_vgic_cpu_early_init(): initialization of static data that
- *   doesn't depend on any sizing information or emulation type. No
- *   allocation is allowed there.
