  	  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:
  	  <http://www.lesswatts.org/projects/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 co-developed by
  	  Hewlett-Packard, Intel, Microsoft, Phoenix, and Toshiba.
  	  The specification is available at:

  	  <http://www.acpi.info>

  	default y

  config ACPI_PROCFS

  	bool "Deprecated /proc/acpi files"
  	depends on PROC_FS

  	help

  	  For backwards compatibility, this option allows

  	  deprecated /proc/acpi/ files to exist, even when

  	  they have been replaced by functions in /sys.
  	  The deprecated files (and their replacements) include:

  	  /proc/acpi/sleep (/sys/power/state)

  	  /proc/acpi/info (/sys/module/acpi/parameters/acpica_version)

  	  /proc/acpi/dsdt (/sys/firmware/acpi/tables/DSDT)

  	  /proc/acpi/debug_level (/sys/module/acpi/parameters/debug_level)
  
  	  This option has no effect on /proc/acpi/ files
  	  and functions which do not yet exist in /sys.
  
  	  Say N to delete /proc/acpi/ files that have moved to /sys/

  config ACPI_PROCFS_POWER

  	bool "Deprecated power /proc/acpi directories"

  	depends on PROC_FS
  	default y

  	help

  	  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            they have been replaced by functions in /sys.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

  	  Say N to delete power /proc/acpi/ directories that have moved to /sys/

  config ACPI_SYSFS_POWER
  	bool "Future power /sys interface"

  	default y

  	help

  	  Say N to disable power /sys interface

  config ACPI_PROC_EVENT
  	bool "Deprecated /proc/acpi/event support"
  	depends on PROC_FS

  	default y

  	help
  	  A user-space daemon, acpid, typically reads /proc/acpi/event
  	  and handles all ACPI-generated events.

  	  These events are now delivered to user-space either
  	  via the input layer or as netlink events.

  	  This build option enables the old code for legacy

  	  user-space implementation.  After some time, this will
  	  be moved under CONFIG_ACPI_PROCFS, and then deleted.

  	  Say Y here to retain the old behaviour.  Say N if your
  	  user-space is newer than kernel 2.6.23 (September 2007).

  config ACPI_AC
  	tristate "AC Adapter"

  	depends on X86

  	default y

  	help

  	  This driver supports the AC Adapter object, which indicates
  	  whether a system is on AC or not.  If you have a system that can

  	  switch between A/C and battery, say Y.

  	  To compile this driver as a module, choose M here:
  	  the module will be called ac.

  config ACPI_BATTERY
  	tristate "Battery"

  	depends on X86

  	default y

  	help
  	  This driver adds support for battery information through
  	  /proc/acpi/battery. If you have a mobile system with a battery, 
  	  say Y.

  	  To compile this driver as a module, choose M here:
  	  the module will be called battery.

  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 /proc/acpi/event and perform 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
  	tristate "Video"

  	depends on X86 && BACKLIGHT_CLASS_DEVICE && VIDEO_OUTPUT_CONTROL

  	depends on INPUT

  	select THERMAL

  	help

  	  This driver implements the ACPI Extensions For Display Adapters

  	  for integrated graphics devices on motherboard, as specified in

  	  ACPI 2.0 Specification, Appendix B.  This supports basic operations
  	  such as defining the video POST device, retrieving EDID information,
  	  and setting up a video output.
  
  	  To compile this driver as a module, choose M here:
  	  the module will be called video.

  
  config ACPI_FAN
  	tristate "Fan"

  	select THERMAL

  	default y

  	help

  	  This driver supports ACPI fan devices, allowing user-mode

  	  applications to perform basic fan control (on, off, status).

  	  To compile this driver as a module, choose M here:
  	  the module will be called fan.

  config ACPI_DOCK

  	bool "Dock"

  	depends on EXPERIMENTAL

  	help

  	  This driver supports ACPI-controlled docking stations and removable
  	  drive bays such as the IBM Ultrabay and the Dell Module Bay.

  config ACPI_PROCESSOR
  	tristate "Processor"

  	select THERMAL

  	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_HOTPLUG_CPU

  	bool

  	default y

  
  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_NUMA
  	bool "NUMA support"
  	depends on NUMA

  	depends on (X86 || IA64)

  config ACPI_CUSTOM_DSDT_FILE
  	string "Custom DSDT Table file to include"
  	default ""

  	depends on !STANDALONE

  	help

  	  This option supports a custom DSDT by linking it into the kernel.
  	  See Documentation/acpi/dsdt-override.txt

  	  Enter the full path name to the file which includes the AmlCode
  	  declaration.

  	  If unsure, don't enter a file name.
  
  config ACPI_CUSTOM_DSDT
  	bool
  	default ACPI_CUSTOM_DSDT_FILE != ""

  config ACPI_BLACKLIST_YEAR

  	int "Disable ACPI for systems before Jan 1st this year" if X86_32

  	default 0
  	help

  	  Enter a 4-digit year, e.g., 2001, to disable ACPI by default

  	  on platforms with DMI BIOS date before January 1st that year.
  	  "acpi=force" can be used to override this mechanism.
  
  	  Enter 0 to disable this mechanism and allow ACPI to
  	  run by default no matter what the year.  (default)
  
  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_DEBUG_FUNC_TRACE
  	bool "Additionally enable ACPI function tracing"
  	default n
  	depends on ACPI_DEBUG
  	help
  	  ACPI Debug Statements slow down ACPI processing. Function trace
  	  is about half of the penalty and is rarely useful.

  config ACPI_PCI_SLOT
  	tristate "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.
  
  	  To compile this driver as a module, choose M here:
  	  the module will be called pci_slot.

  config X86_PM_TIMER

  	bool "Power Management Timer Support" if EMBEDDED

  	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

  	tristate "Container and Module Devices (EXPERIMENTAL)"

  	depends on EXPERIMENTAL
  	default (ACPI_HOTPLUG_MEMORY || ACPI_HOTPLUG_CPU || ACPI_HOTPLUG_IO)

  	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
  	tristate "Memory Hotplug"

  	depends on MEMORY_HOTPLUG

  	default n
  	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_SBS

  	tristate "Smart Battery System"

  	depends on X86

  	help

  	  This driver supports the Smart Battery System, another

  	  type of access to battery information, found on some laptops.

  	  To compile this driver as a module, choose M here:
  	  the modules will be called sbs and sbshc.
