+	default y
+	help
+	  Advanced Configuration and Power Interface (ACPI) support for 
+	  Linux requires an ACPI-compliant platform (hardware/firmware),
+	  and assumes the presence of OS-directed configuration and power
+	  management (OSPM) software.  This option will enlarge your 
+	  kernel by about 70K.
+
+	  Linux ACPI provides a robust functional replacement for several 
+	  legacy configuration and power management interfaces, including
+	  the Plug-and-Play BIOS specification (PnP BIOS), the 
+	  MultiProcessor Specification (MPS), and the Advanced Power 
+	  Management (APM) specification.  If both ACPI and APM support 
+	  are configured, ACPI is used.
+
+	  The project home page for the Linux ACPI subsystem is here:
+	  <https://01.org/linux-acpi>
+
+	  Linux support for ACPI is based on Intel Corporation's ACPI
+	  Component Architecture (ACPI CA).  For more information on the
+	  ACPI CA, see:
+	  <http://acpica.org/>
+
+	  ACPI is an open industry specification originally co-developed by
+	  Hewlett-Packard, Intel, Microsoft, Phoenix, and Toshiba. Currently,
+	  it is developed by the ACPI Specification Working Group (ASWG) under
+	  the UEFI Forum and any UEFI member can join the ASWG and contribute
+	  to the ACPI specification.
+	  The specification is available at:
+	  <http://www.acpi.info>
+	  <http://www.uefi.org/acpi/specs>

+	  For backwards compatibility, this option allows
+          deprecated power /proc/acpi/ directories to exist, even when
+          they have been replaced by functions in /sys.
+          The deprecated directories (and their replacements) include:
+	  /proc/acpi/battery/* (/sys/class/power_supply/*)
+	  /proc/acpi/ac_adapter/* (sys/class/power_supply/*)
+	  This option has no effect on /proc/acpi/ directories
+	  and functions, which do not yet exist in /sys
+	  This option, together with the proc directories, will be

+	help
+	  Say N to disable Embedded Controller /sys/kernel/debug interface
+
+	  Be aware that using this interface can confuse your Embedded
+	  Controller in a way that a normal reboot is not enough. You then
+	  have to power off your system, and remove the laptop battery for
+	  some seconds.
+	  An Embedded Controller typically is available on laptops and reads
+	  sensor values like battery state and temperature.
+	  The kernel accesses the EC through ACPI parsed code provided by BIOS
+	  tables. This option allows to access the EC directly without ACPI
+	  code being involved.
+	  Thus this option is a debug option that helps to write ACPI drivers
+	  and can be used to identify ACPI code or EC firmware bugs.

+
+config ACPI_BUTTON
+	tristate "Button"
+	depends on INPUT
+	default y
+	help
+	  This driver handles events on the power, sleep, and lid buttons.
+	  A daemon reads events from input devices or via netlink and
+	  performs user-defined actions such as shutting down the system.
+	  This is necessary for software-controlled poweroff.
+
+	  To compile this driver as a module, choose M here:
+	  the module will be called button.
+
+config ACPI_VIDEO

+	select THERMAL
+	select CPU_IDLE
+	depends on X86 || IA64
+	default y
+	help
+	  This driver installs ACPI as the idle handler for Linux and uses
+	  ACPI C2 and C3 processor states to save power on systems that
+	  support it.  It is required by several flavors of cpufreq
+	  performance-state drivers.
+
+	  To compile this driver as a module, choose M here:
+	  the module will be called processor.
+
+config ACPI_IPMI
+	tristate "IPMI"
+	depends on IPMI_SI
+	default n
+	help
+	  This driver enables the ACPI to access the BMC controller. And it
+	  uses the IPMI request/response message to communicate with BMC
+	  controller, which can be found on on the server.
+
+	  To compile this driver as a module, choose M here:

+config ACPI_PROCESSOR_AGGREGATOR
+	tristate "Processor Aggregator"
+	depends on ACPI_PROCESSOR
+	depends on X86
+	help
+	  ACPI 4.0 defines processor Aggregator, which enables OS to perform
+	  specific processor configuration and control that applies to all
+	  processors in the platform. Currently only logical processor idling
+	  is defined, which is to reduce power consumption. This driver
+	  supports the new device.
+
+config ACPI_THERMAL
+	tristate "Thermal Zone"
+	depends on ACPI_PROCESSOR
+	select THERMAL
+	default y
+	help
+	  This driver supports ACPI thermal zones.  Most mobile and
+	  some desktop systems support ACPI thermal zones.  It is HIGHLY
+	  recommended that this option be enabled, as your processor(s)
+	  may be damaged without it.
+
+	  To compile this driver as a module, choose M here:
+	  the module will be called thermal.

+config ACPI_INITRD_TABLE_OVERRIDE
+	bool "ACPI tables override via initrd"
+	depends on BLK_DEV_INITRD && X86
+	default n
+	help
+	  This option provides functionality to override arbitrary ACPI tables
+	  via initrd. No functional change if no ACPI tables are passed via
+	  initrd, therefore it's safe to say Y.
+	  See Documentation/acpi/initrd_table_override.txt for details
+
+config ACPI_DEBUG
+	bool "Debug Statements"
+	default n
+	help
+	  The ACPI subsystem can produce debug output.  Saying Y enables this
+	  output and increases the kernel size by around 50K.
+
+	  Use the acpi.debug_layer and acpi.debug_level kernel command-line
+	  parameters documented in Documentation/acpi/debug.txt and
+	  Documentation/kernel-parameters.txt to control the type and
+	  amount of debug output.
+
+config ACPI_PCI_SLOT
+	bool "PCI slot detection driver"
+	depends on SYSFS
+	default n
+	help
+	  This driver creates entries in /sys/bus/pci/slots/ for all PCI
+	  slots in the system.  This can help correlate PCI bus addresses,
+	  i.e., segment/bus/device/function tuples, with physical slots in
+	  the system.  If you are unsure, say N.
+
+config X86_PM_TIMER
+	bool "Power Management Timer Support" if EXPERT
+	depends on X86
+	default y
+	help
+	  The Power Management Timer is available on all ACPI-capable,
+	  in most cases even if ACPI is unusable or blacklisted.
+
+	  This timing source is not affected by power management features
+	  like aggressive processor idling, throttling, frequency and/or
+	  voltage scaling, unlike the commonly used Time Stamp Counter
+	  (TSC) timing source.
+
+	  You should nearly always say Y here because many modern
+	  systems require this timer. 
+
+config ACPI_CONTAINER
+	bool "Container and Module Devices"
+	default (ACPI_HOTPLUG_MEMORY || ACPI_HOTPLUG_CPU)
+	help
+	  This driver supports ACPI Container and Module devices (IDs
+	  ACPI0004, PNP0A05, and PNP0A06).
+
+	  This helps support hotplug of nodes, CPUs, and memory.
+
+	  To compile this driver as a module, choose M here:
+	  the module will be called container.
+
+config ACPI_HOTPLUG_MEMORY
+	bool "Memory Hotplug"
+	depends on MEMORY_HOTPLUG
+	help
+	  This driver supports ACPI memory hotplug.  The driver
+	  fields notifications on ACPI memory devices (PNP0C80),
+	  which represent memory ranges that may be onlined or
+	  offlined during runtime.
+
+	  If your hardware and firmware do not support adding or
+	  removing memory devices at runtime, you need not enable
+	  this driver.
+
+	  To compile this driver as a module, choose M here:
+	  the module will be called acpi_memhotplug.
+
+config ACPI_HOTPLUG_IOAPIC

+
+config ACPI_HED
+	tristate "Hardware Error Device"
+	help
+	  This driver supports the Hardware Error Device (PNP0C33),
+	  which is used to report some hardware errors notified via
+	  SCI, mainly the corrected errors.
+
+config ACPI_CUSTOM_METHOD
+	tristate "Allow ACPI methods to be inserted/replaced at run time"
+	depends on DEBUG_FS
+	default n
+	help
+	  This debug facility allows ACPI AML methods to be inserted and/or
+	  replaced without rebooting the system. For details refer to:
+	  Documentation/acpi/method-customizing.txt.
+
+	  NOTE: This option is security sensitive, because it allows arbitrary
+	  kernel memory to be written to by root (uid=0) users, allowing them
+	  to bypass certain security measures (e.g. if root is not allowed to
+	  load additional kernel modules after boot, this feature may be used
+	  to override that restriction).
+
+config ACPI_BGRT
+	bool "Boottime Graphics Resource Table support"
+	depends on EFI && X86
+        help
+	  This driver adds support for exposing the ACPI Boottime Graphics
+	  Resource Table, which allows the operating system to obtain
+	  data from the firmware boot splash. It will appear under
+	  /sys/firmware/acpi/bgrt/ .
+
+config ACPI_REDUCED_HARDWARE_ONLY
+	bool "Hardware-reduced ACPI support only" if EXPERT
+	def_bool n
+	help
+	  This config item changes the way the ACPI code is built.  When this
+	  option is selected, the kernel will use a specialized version of
+	  ACPICA that ONLY supports the ACPI "reduced hardware" mode.  The
+	  resulting kernel will be smaller but it will also be restricted to
+	  running in ACPI reduced hardware mode ONLY.
+
+	  If you are unsure what to do, do not enable this option.

+	tristate "Extended Error Log support"
+	depends on X86_MCE && X86_LOCAL_APIC
+	select UEFI_CPER
+	select RAS
+	default n
+	help
+	  Certain usages such as Predictive Failure Analysis (PFA) require
+	  more information about the error than what can be described in
+	  processor machine check banks. Most server processors log
+	  additional information about the error in processor uncore
+	  registers. Since the addresses and layout of these registers vary
+	  widely from one processor to another, system software cannot
+	  readily make use of them. To complicate matters further, some of
+	  the additional error information cannot be constructed without
+	  detailed knowledge about platform topology.
+
+	  Enhanced MCA Logging allows firmware to provide additional error
+	  information to system software, synchronous with MCE or CMCI. This
+	  driver adds support for that functionality with corresponding
+	  tracepoint which carries that information to userspace.
