+The bttv driver
+===============
+
+Release notes for bttv
+----------------------
+
+You'll need at least these config options for bttv:
+
+.. code-block:: none
+
+ 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:
+
+.. code-block:: none
+
+ 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:
+
+.. code-block:: none
+
+ 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 at
+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).
+
+Modprobe options
+----------------
+
+Note: "modinfo <module>" prints various information about a kernel
+module, among them a complete and up-to-date list of insmod options.
+This list tends to be outdated because it is updated manually ...
+
+==========================================================================
+
+bttv.o
+
+.. code-block:: none
+
+ 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

+
+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).
+
+Bttv quirks
+-----------
+
+Below is what the bt878 data book says about the PCI bug compatibility
+modes of the bt878 chip.
+
+The triton1 insmod option sets the EN_TBFX bit in the control register.
+The vsfx insmod option does the same for EN_VSFX bit. If you have
+stability problems you can try if one of these options makes your box
+work solid.
+
+drivers/pci/quirks.c knows about these issues, this way these bits are
+enabled automagically for known-buggy chipsets (look at the kernel
+messages, bttv tells you).
+
+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:
+
+.. code-block:: none
+
+ 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:
+
+.. code-block:: c
+
+ 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
+doesn't 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:
+
+.. code-block:: none
+
+ 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:
+
+.. code-block:: none
+
+ 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:
+
+.. code-block:: none
+
+ 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.

+Author of this section: 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
+the key code is placed in the GPIO port).
+
+I don't yet have any application to test the radio support. The tuner
+frequency setting should work but it is possible that the audio multiplexer
+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
+ on their server are the full data-sheets, but don't ask how I found it.
+
+To use the driver I use the following options, the tuner and pll settings might
+be different in your country

+The cafe_ccic driver
+====================
+
+Author: Jonathan Corbet <corbet@lwn.net>
+
+Introdution
+-----------
+
+"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:
+
+.. code-block:: none
+
+ $ 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.
+
+Load time options
+-----------------
+
+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.

+The cpia2 driver
+================
+
+Authors: 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.
+
+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.
+
+Making and installing the stv672 driver modules
+-----------------------------------------------
+
+Requirements
+~~~~~~~~~~~~
+
+Video4Linux must be either compiled into the kernel or
+available as a module. Video4Linux2 is automatically detected and made
+available at compile time.
+
+Setup
+~~~~~
+
+Use 'modprobe cpia2' to load and 'modprobe -r cpia2' to unload. This
+may be done automatically by your distribution.
+
+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:
+
+.. code-block:: none
+
+ options cpia2 num_buffers=3 buffer_size=65535
+
+If the driver is compiled into the kernel, at boot time specify them
+like this:
+
+.. code-block:: none
+
+ 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.
+

+========== ========== ======== =====
+
+Table: Image size(bytes)
+
+
+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.
+
+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.
+
+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.
+
+Programmer's overview of cpia2 driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+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

+The cx18 driver
+===============
+
+.. note::
+
+ This documentation is outdated.
+
+Some notes regarding the cx18 driver for the Conexant CX23418 MPEG
+encoder chip:
+
+1) Currently supported are:
+
+ - Hauppauge HVR-1600
+ - Compro VideoMate H900
+ - Yuan MPC718
+ - Conexant Raptor PAL/SECAM devkit
+
+2) Some people have problems getting the i2c bus to work.
+ The symptom is that the eeprom cannot be read and the card is
+ unusable. This is probably fixed, but if you have problems
+ then post to the video4linux or ivtv-users mailing list.
+
+3) VBI (raw or sliced) has not yet been implemented.
+
+4) MPEG indexing is not yet implemented.
+
+5) The driver is still a bit rough around the edges, this should
+ improve over time.
+
+
+Firmware:
+
+You can obtain the firmware files here:
+
+http://dl.ivtvdriver.org/ivtv/firmware/cx18-firmware.tar.gz
+
+Untar and copy the .fw files to your firmware directory.

+The cx2341x driver
+==================
+
+Memory at cx2341x chips
+-----------------------
+
+This section 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:
+
+ .. code-block:: none
+
+ 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.
+
+.. code-block:: none
+
+ 0x00000000-0x00ffffff Encoder memory space
+ 0x00000000-0x0003ffff Encode.rom
+ ???-??? MPEG buffer(s)
+ ???-??? Raw video capture buffer(s)
+ ???-??? Raw audio capture buffer(s)
+ ???-??? Display buffers (6 or 9)
+
+ 0x01000000-0x01ffffff Decoder memory space
+ 0x01000000-0x0103ffff Decode.rom
+ ???-??? MPEG buffers(s)
+ 0x0114b000-0x0115afff Audio.rom (deprecated?)
+
+ 0x02000000-0x0200ffff Register Space
+
+Registers
+~~~~~~~~~
+
+The registers occupy the 64k space starting at the 0x02000000 offset from BAR0.
+All of these registers are 32 bits wide.
+
+.. code-block:: none
+
+ DMA Registers 0x000-0xff:
+
+ 0x00 - Control:
+ 0=reset/cancel, 1=read, 2=write, 4=stop
+ 0x04 - DMA status:
+ 1=read busy, 2=write busy, 4=read error, 8=write error, 16=link list error
+ 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.

+
+
+How to call the firmware API
+----------------------------
+
+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:
+
+.. code-block:: none
+
+ 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 this
+chapter.
+
+The return value is a 32-bit enumerator. Only two values are currently defined:
+
+- 0=success
+- -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 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.

+
+Param[0]
+^^^^^^^^
+
+Display 0=last frame, 1=black
+
+.. note::
+
+ this takes effect immediately, so if you want to wait for a PTS,

+
+
+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.

+
+ 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.

+
+ NOTE: For both registers, the resulting image must be fully visible on

+
+ 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.

+
+ 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.

+
+The cx231xx DMA engine
+----------------------
+
+
+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
+- bit 1: write completed
+- bit 2: DMA read error
+- bit 3: DMA write error
+- bit 4: Scatter-Gather array error
+
+Non-compressed file format
+--------------------------
+
+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
+---------------------------------------------------------
+
+Author: Hans Verkuil <hverkuil@xs4all.nl>
+
+
+This section 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:
+
+.. code-block:: c
+
+ #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)

+The cx88 driver
+===============
+
+Author: Gerd Hoffmann
+
+This is a v4l2 device driver for the cx2388x chip.
+
+
+Current status
+--------------
+
+video
+ - Works.
+ - Overlay isn't supported.
+
+audio
+ - Works. The TV standard detection is made by the driver, as the
+ hardware has bugs to auto-detect.
+ - audio data dma (i.e. recording without loopback cable to the
+ sound card) is supported via cx88-alsa.
+
+vbi
+ - Works.
+
+
+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:
+
+.. code-block:: none
+
+ 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. We 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
+

+
+Hauppauge WinTV cx88 IR information
+-----------------------------------
+
+The controls for the mux are GPIO [0,1] for source, and GPIO 2 for muting.
+
+====== ======== =================================================
+GPIO0 GPIO1
+====== ======== =================================================
+ 0 0 TV Audio
+ 1 0 FM radio
+ 0 1 Line-In
+ 1 1 Mono tuner bypass or CD passthru (tuner specific)
+====== ======== =================================================
+
+GPIO 16(I believe) is tied to the IR port (if present).
+
+
+From the data sheet:
+
+- Register 24'h20004 PCI Interrupt Status
+
+ - 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
+- 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.

+
+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.
+
+To be done
+----------
+
+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.

+The Samsung S5P/EXYNOS4 FIMC driver
+===================================
+
+Copyright |copy| 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.
+
+Supported SoCs
+--------------
+
+S5PC100 (mem-to-mem only), S5PV210, EXYNOS4210
+
+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

+
+User space interfaces
+---------------------
+
+Media device interface
+~~~~~~~~~~~~~~~~~~~~~~
+
+The driver supports Media Controller API as defined at :ref:`media_controller`.
+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.
+
+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.
+
+Capture video node
+~~~~~~~~~~~~~~~~~~
+
+The driver supports V4L2 Video Capture Interface as defined at
+:ref:`devices`.
+
+At the capture and mem-to-mem video nodes only the multi-planar API is
+supported. For more details see: :ref:`planar-apis`.
+
+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).
+
+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):
+
+.. code-block:: none
+
+ # 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):
+
+.. code-block:: none
+
+ # 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.
+
+.. code-block:: none
+
+ # 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:
+
+.. code-block:: none
+
+ # 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).

+
+The ivtv driver
+===============
+
+Author: Hans Verkuil <hverkuil@xs4all.nl>
+
+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:
+
+ https://linuxtv.org/downloads/firmware/#conexant
+
+ #) '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.
+
+IMPORTANT: In case of problems first read this page:

+
+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:
+
+.. code-block:: none
+
+ 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:
+
+ .. code-block:: none
+
+ 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:
+
+ .. code-block:: none
+
+ 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.

+Vaio Picturebook Motion Eye Camera Driver
+=========================================
+
+Copyright |copy| 2001-2004 Stelian Pop <stelian@popies.net>
+
+Copyright |copy| 2001-2002 Alcôve <www.alcove.com>
+
+Copyright |copy| 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:
+
+.. code-block:: none
+
+ 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:
+
+.. code-block:: none
+
+ alias char-major-81 videodev
+ alias char-major-81-0 meye
+ options meye gbuffers=32
+
+Usage:
+------
+
+.. code-block:: none
+
+ 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 and 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 and 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.

+OMAP 3 Image Signal Processor (ISP) driver

+
+
+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 [#f2]_.
+
+
+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 [#f1]_.
+
+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
+are not part of the TRM.
+
+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 [#f1]_ 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 [#f2]_, 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:

+The pvrusb2 driver
+==================
+
+Author: Mike Isely <isely@pobox.com>
+
+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:
+
+1. Low level wire-protocol implementation with the device.
+
+2. I2C adaptor implementation and corresponding I2C client drivers
+ implemented elsewhere in V4L.
+
+3. High level hardware driver implementation which coordinates all
+ activities that ensure correct operation of the device.
+
+4. 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.
+
+5. 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.
+
+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).

+PXA-Camera Host Driver
+======================
+
+Author: Robert Jarzmik <robert.jarzmik@free.fr>
+
+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

+ - "QCI: stop" means the QCI interface is not enabled
+ - "DMA: stop" means all 3 DMA channels are stopped
+ - "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
+
+.. code-block:: none
+
+ +------------+-----+---------------+-----------------+
+ | 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 :
+
+.. code-block:: none
+
+ Videobuffer 1 Videobuffer 2
+ +---------+----+---+ +----+----+----+---+
+ | d0 | .. | dN | l | | d0 | .. | dN | f |
+ +---------+----+-|-+ ^----+----+----+---+
+ | |
+ +----+
+
+After the chaining is finished, the chain looks like :
+
+.. code-block:: none
+
+ 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
+
+.. code-block:: none
+
+ =>
+ 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 !!!)
+
+.. code-block:: none
+
+ 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.

+The Radiotrack radio driver
+===========================
+
+Author: Stephen M. Benoit <benoits@servicepro.com>
+
+Date: Dec 14, 1996
+
+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:
+
+.. code-block:: none
+
+ MSb LSb
+ +------+------+------+--------+--------+-------+---------+--------+
+ | VolA | VolB | ???? | Stereo | Radio | TuneA | TuneB | Tune |
+ | (+) | (-) | | Detect | Audio | (bit) | (latch) | Update |

+The saa7134 driver
+==================
+
+Author Gerd Hoffmann
+
+
+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:
+
+.. code-block:: none
+
+ 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.

+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)

+The Silicon Labs Si470x FM Radio Receivers driver
+=================================================
+
+Copyright |copy| 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:
+
+.. code-block:: none
+
+ 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):
+
+.. code-block:: none
+
+ cat /dev/dsp1 > /dev/dsp
+
+If you use sox + OSS try:
+
+.. code-block:: none
+
+ sox -2 --endian little -r 96000 -t oss /dev/dsp1 -t oss /dev/dsp
+
+or using sox + alsa:
+
+.. code-block:: none
+
+ sox --endian little -c 2 -S -r 96000 -t alsa hw:1 -t alsa -r 96000 hw:0
+
+If you use arts try:
+
+.. code-block:: none
+
+ arecord -D hw:1,0 -r96000 -c2 -f S16_LE | artsdsp aplay -B -
+
+If you use mplayer try:
+
+.. code-block:: none
+
+ 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.

+The Silicon Labs Si4713 FM Radio Transmitter Driver
+===================================================
+
+Copyright |copy| 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:
+
+.. code-block:: none

+
+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.

+ 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_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:
+
+.. code-block:: none
+
+ 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:
+
+.. code-block:: none
+
+ # v4l2-ctl -d /dev/radio0 --set-ctrl=rds_ps_name="Dummy"

+The SI476x Driver
+=================
+
+Copyright |copy| 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

+ - 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
+
+.. code-block:: none
+
+ soc_camera_host_register(struct soc_camera_host *);
+
+function. The host object can be initialized as follows:
+
+.. code-block:: none
+
+ 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:
+
+.. code-block:: none
+
+ 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.

+The 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
+---------------------------
+
+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.
+
+
+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.
+
+
+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.
+
+
+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.
+
+
+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.
+
+**Data types**:
+

+
+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**:
+
+.. code-block:: none
+
+ * struct uvc_xu_control_query

+Infrared remote control support in video4linux drivers
+======================================================
+
+Authors: Gerd Hoffmann, Mauro Carvalho Chehab
+
+Basics
+------
+
+Most analog and digital TV boards support remote controllers. Several of
+them have a microprocessor that receives the IR carriers, convert into
+pulse/space sequences and then to scan codes, returning such codes to
+userspace ("scancode mode"). Other boards return just the pulse/space
+sequences ("raw mode").
+
+The support for remote controller in scancode mode is provided by the
+standard Linux input layer. The support for raw mode is provided via LIRC.
+
+In order to check the support and test it, it is suggested to download
+the `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_. It provides
+two tools to handle remote controllers:
+
+- ir-keytable: provides a way to query the remote controller, list the
+ protocols it supports, enable in-kernel support for IR decoder or
+ switch the protocol and to test the reception of scan codes;
+
+- ir-ctl: provide tools to handle remote controllers that support raw mode
+ via LIRC interface.
+
+Usually, the remote controller module is auto-loaded when the TV card is
+detected. However, for a few devices, you need to manually load the
+ir-kbd-i2c module.
+
+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.
+The udev/systemd will automatically create the devices. If you install
+the `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_, it may also
+automatically load a different keytable than the default one. Please see
+`v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_ ir-keytable.1
+man page for details.
+
+The ir-keytable tool is 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 any other input utility that changes
+the keymaps, like the input kbd utility.
+
+
+Using with lircd
+================
+
+The latest versions of the lircd daemon supports reading events from the
+linux input layer (via event device). It also supports receiving IR codes
+in lirc mode.
+
+
+Using without lircd
+===================
+
+Xorg recognizes several IR keycodes that have its numerical value lower
+than 247. With the advent of Wayland, the input driver got updated too,
+and should now accept all keycodes. Yet, you may want to just reasign
+the keycodes to something that your favorite media application likes.
+
+This can be done by setting
+`v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_ to load your own
+keytable in runtime. Please read ir-keytable.1 man page for details.

+The Virtual Video Test Driver (vivid)
+=====================================
+
+This driver emulates video4linux hardware of various types: video capture, video
+output, vbi capture and output, radio receivers and transmitters and a software
+defined radio receiver. In addition a simple framebuffer device is available for
+testing capture and output overlays.
+
+Up to 64 vivid instances can be created, each with up to 16 inputs and 16 outputs.
+
+Each input can be a webcam, TV capture device, S-Video capture device or an HDMI
+capture device. Each output can be an S-Video output device or an HDMI output
+device.
+
+These inputs and outputs act exactly as a real hardware device would behave. This
+allows you to use this driver as a test input for application development, since
+you can test the various features without requiring special hardware.
+
+This document describes the features implemented by this driver:
+
+- Support for read()/write(), MMAP, USERPTR and DMABUF streaming I/O.
+- A large list of test patterns and variations thereof
+- Working brightness, contrast, saturation and hue controls
+- Support for the alpha color component
+- Full colorspace support, including limited/full RGB range
+- All possible control types are present
+- Support for various pixel aspect ratios and video aspect ratios
+- Error injection to test what happens if errors occur
+- Supports crop/compose/scale in any combination for both input and output
+- Can emulate up to 4K resolutions
+- All Field settings are supported for testing interlaced capturing
+- Supports all standard YUV and RGB formats, including two multiplanar YUV formats
+- Raw and Sliced VBI capture and output support
+- Radio receiver and transmitter support, including RDS support
+- Software defined radio (SDR) support
+- Capture and output overlay support
+
+These features will be described in more detail below.
+
+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:
+
+ .. code-block:: none
+
+ 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:
+
+ .. code-block:: none
+
+ 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:
+
+ .. code-block:: none
+
+ 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:
+
+ .. code-block:: none
+
+ 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.
+
+
+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.
+
+
+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.
+
+
+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.
+
+
+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 with the exception of the
+physical address. See the CEC section for more details.
+
+There is a maximum of 15 HDMI inputs (if there are more, then they will be
+reduced to 15) since that's the limitation of the EDID physical address.
+
+
+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.
+
+
+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.
+
+
+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.
+
+There is a maximum of 15 HDMI outputs (if there are more, then they will be
+reduced to 15) since that's the limitation of the EDID physical address. See
+also the CEC section for more details.
+
+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.
+
+
+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.
+
+
+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.
+
+
+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().
+
+
+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).
+
+
+Controls
+--------
+
+Different devices support different controls. The sections below will describe
+each control and which devices support them.
+
+
+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.
+
+
+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.
+
+
+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.
+
+
+Vivid Controls
+~~~~~~~~~~~~~~
+
+These vivid custom controls control the image generation, error injection, etc.
+
+
+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.
+
+
+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.
+
+
+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).
+
+
+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.
+
+
+VBI Raw Capture Controls
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+- Interlaced VBI Format:
+
+ if set, then the raw VBI data will be interlaced instead
+ of providing it grouped by field.
+
+
+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.
+
+
+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::
+ 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.
+
+- RDS Rx I/O Mode:
+
+ this can be "Block I/O" where the RDS blocks have to be read()
+ by the application, or "Controls" where the RDS data is provided by
+ the RDS controls mentioned above.
+
+
+FM Radio Modulator Controls
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- RDS Program ID:
+
+
+- RDS Program Type:
+
+
+- RDS PS Name:
+
+
+- RDS Radio Text:
+
+
+- RDS Stereo:
+
+
+- RDS Artificial Head:
+
+
+- RDS Compressed:
+
+
+- RDS Dynamic PTY:
+
+
+- RDS Traffic Announcement:
+
+
+- RDS Traffic Program:
+
+
+- RDS Music:
+
+ these are all controls that set the RDS data that is transmitted by
+ the FM modulator.
+
+- RDS Tx I/O Mode:
+
+ this can be "Block I/O" where the application has to use write()
+ to pass the RDS blocks to the driver, or "Controls" where the RDS data
+ is Provided by the RDS controls mentioned above.
+
+
+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.

+
+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.
+
+
+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.
+
+
+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.
+
+
+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.
+
+
+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:
+
+.. code-block:: none
+
+ $ 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:
+
+.. code-block:: none
+
+ $ v4l2-ctl -d1 --stream-out-mmap
+
+And yet another console:
+
+.. code-block:: none
+
+ $ qv4l2
+
+and start streaming.
+
+As you can see, this is not for the faint of heart...
+
+
+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.
+
+
+CEC (Consumer Electronics Control)
+----------------------------------
+
+If there are HDMI inputs then a CEC adapter will be created that has
+the same number of input ports. This is the equivalent of e.g. a TV that
+has that number of inputs. Each HDMI output will also create a
+CEC adapter that is hooked up to the corresponding input port, or (if there
+are more outputs than inputs) is not hooked up at all. In other words,
+this is the equivalent of hooking up each output device to an input port of
+the TV. Any remaining output devices remain unconnected.
+
+The EDID that each output reads reports a unique CEC physical address that is
+based on the physical address of the EDID of the input. So if the EDID of the
+receiver has physical address A.B.0.0, then each output will see an EDID
+containing physical address A.B.C.0 where C is 1 to the number of inputs. If
+there are more outputs than inputs then the remaining outputs have a CEC adapter
+that is disabled and reports an invalid physical address.
+
+
+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
+- 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.
+- Changing the EDID should cause hotplug detect emulation to happen.

+
+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.

+
+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

+
+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.
+
+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.
+
+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)
+
+
+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.
+
+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.

+Zoran 364xx based USB webcam module
+===================================
+
+site: http://royale.zerezo.com/zr364xx/
+
+mail: royale@zerezo.com
+
+.. note:
+
+ This documentation is outdated
+
+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
