	  For more information about this driver see
	  <file:Documentation/laptops/thinkpad-acpi.txt> and
	  <http://ibm-acpi.sf.net/> .

	  This driver was formerly known as ibm-acpi.

	  If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.

config THINKPAD_ACPI_DEBUGFACILITIES
	bool "Maintainer debug facilities"
	depends on THINKPAD_ACPI
	default n
	---help---
	  Enables extra stuff in the thinkpad-acpi which is completely useless
	  for normal use.  Read the driver source to find out what it does.

	  Say N here, unless you were told by a kernel maintainer to do
	  otherwise.

config THINKPAD_ACPI_DEBUG
	bool "Verbose debug mode"
	depends on THINKPAD_ACPI
	default n
	---help---
	  Enables extra debugging information, at the expense of a slightly
	  increase in driver size.

	  If you are not sure, say N here.

config THINKPAD_ACPI_UNSAFE_LEDS
	bool "Allow control of important LEDs (unsafe)"
	depends on THINKPAD_ACPI
	default n
	---help---
	  Overriding LED state on ThinkPads can mask important
	  firmware alerts (like critical battery condition), or misled
	  the user into damaging the hardware (undocking or ejecting
	  the bay while buses are still active), etc.

	  LED control on the ThinkPad is write-only (with very few
	  exceptions on very ancient models), which makes it
	  impossible to know beforehand if important information will
	  be lost when one changes LED state.

	  Users that know what they are doing can enable this option
	  and the driver will allow control of every LED, including
	  the ones on the dock stations.

	  Never enable this option on a distribution kernel.

	  Say N here, unless you are building a kernel for your own
	  use, and need to control the important firmware LEDs.

config THINKPAD_ACPI_DOCK
	bool "Legacy Docking Station Support"
	depends on THINKPAD_ACPI
	depends on ACPI_DOCK=n
	default n
	---help---
	  Allows the thinkpad_acpi driver to handle docking station events.
	  This support was made obsolete by the generic ACPI docking station
	  support (CONFIG_ACPI_DOCK).  It will allow locking and removing the
	  laptop from the docking station, but will not properly connect PCI
	  devices.

	  If you are not sure, say N here.

config THINKPAD_ACPI_BAY
	bool "Legacy Removable Bay Support"
	depends on THINKPAD_ACPI
	default y
	---help---
	  Allows the thinkpad_acpi driver to handle removable bays.  It will
	  electrically disable the device in the bay, and also generate
	  notifications when the bay lever is ejected or inserted.

	  If you are not sure, say Y here.

config THINKPAD_ACPI_VIDEO
	bool "Video output control support"
	depends on THINKPAD_ACPI
	default y
	---help---
	  Allows the thinkpad_acpi driver to provide an interface to control
	  the various video output ports.

	  This feature often won't work well, depending on ThinkPad model,
	  display state, video output devices in use, whether there is a X
	  server running, phase of the moon, and the current mood of
	  Schroedinger's cat.  If you can use X.org's RandR to control
	  your ThinkPad's video output ports instead of this feature,
	  don't think twice: do it and say N here to save some memory.

	  If you are not sure, say Y here.

config THINKPAD_ACPI_HOTKEY_POLL
	bool "Support NVRAM polling for hot keys"
	depends on THINKPAD_ACPI
	default y
	---help---
	  Some thinkpad models benefit from NVRAM polling to detect a few of
	  the hot key press events.  If you know your ThinkPad model does not
	  need to do NVRAM polling to support any of the hot keys you use,
	  unselecting this option will save about 1kB of memory.

	  ThinkPads T40 and newer, R52 and newer, and X31 and newer are
	  unlikely to need NVRAM polling in their latest BIOS versions.

	  NVRAM polling can detect at most the following keys: ThinkPad/Access
	  IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
	  Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

	  If you are not sure, say Y here.  The driver enables polling only if
	  it is strictly necessary to do so.

config INTEL_MENLOW
	tristate "Thermal Management driver for Intel menlow platform"
	depends on ACPI_THERMAL
	select THERMAL
	---help---
	  ACPI thermal management enhancement driver on
	  Intel Menlow platform.

	  If unsure, say N.

config EEEPC_LAPTOP
	tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
	depends on ACPI
	depends on INPUT
	depends on EXPERIMENTAL
	depends on RFKILL || RFKILL = n
	select BACKLIGHT_CLASS_DEVICE
	select HWMON
	---help---
	  This driver supports the Fn-Fx keys on Eee PC laptops.
	  It also adds the ability to switch camera/wlan on/off.

	  If you have an Eee PC laptop, say Y or M here.


config ACPI_WMI
	tristate "WMI"
	depends on ACPI
	help
	  This driver adds support for the ACPI-WMI (Windows Management
	  Instrumentation) mapper device (PNP0C14) found on some systems.

	  ACPI-WMI is a proprietary extension to ACPI to expose parts of the
	  ACPI firmware to userspace - this is done through various vendor
	  defined methods and data blocks in a PNP0C14 device, which are then
	  made available for userspace to call.

	  The implementation of this in Linux currently only exposes this to
	  other kernel space drivers.

	  This driver is a required dependency to build the firmware specific
	  drivers needed on many machines, including Acer and HP laptops.

	  It is safe to enable this driver even if your DSDT doesn't define
	  any ACPI-WMI devices.

config ACPI_ASUS
	tristate "ASUS/Medion Laptop Extras"
	depends on ACPI
	select BACKLIGHT_CLASS_DEVICE
	---help---
	  This driver provides support for extra features of ACPI-compatible
	  ASUS laptops. As some of Medion laptops are made by ASUS, it may also
	  support some Medion laptops (such as 9675 for example).  It makes all
	  the extra buttons generate standard ACPI events that go through
	  /proc/acpi/events, and (on some models) adds support for changing the
	  display brightness and output, switching the LCD backlight on and off,
	  and most importantly, allows you to blink those fancy LEDs intended
	  for reporting mail and wireless status.

	  Note: display switching code is currently considered EXPERIMENTAL,
	  toying with these values may even lock your machine.

	  All settings are changed via /proc/acpi/asus directory entries. Owner
	  and group for these entries can be set with asus_uid and asus_gid
	  parameters.

	  More information and a userspace daemon for handling the extra buttons
	  at <http://sourceforge.net/projects/acpi4asus/>.

	  If you have an ACPI-compatible ASUS laptop, say Y or M here. This
	  driver is still under development, so if your laptop is unsupported or
	  something works not quite as expected, please use the mailing list
	  available on the above page (acpi4asus-user@lists.sourceforge.net).

	  NOTE: This driver is deprecated and will probably be removed soon,
	  use asus-laptop instead.

config ACPI_TOSHIBA
	tristate "Toshiba Laptop Extras"
	depends on ACPI
	depends on INPUT
	depends on RFKILL || RFKILL = n
	select INPUT_POLLDEV
	select BACKLIGHT_CLASS_DEVICE
	---help---
	  This driver adds support for access to certain system settings
	  on "legacy free" Toshiba laptops.  These laptops can be recognized by
	  their lack of a BIOS setup menu and APM support.

	  On these machines, all system configuration is handled through the
	  ACPI.  This driver is required for access to controls not covered
	  by the general ACPI drivers, such as LCD brightness, video output,
	  etc.

	  This driver differs from the non-ACPI Toshiba laptop driver (located
	  under "Processor type and features") in several aspects.
	  Configuration is accessed by reading and writing text files in the
	  /proc tree instead of by program interface to /dev.  Furthermore, no
	  power management functions are exposed, as those are handled by the
	  general ACPI drivers.

	  More information about this driver is available at
	  <http://memebeam.org/toys/ToshibaAcpiDriver>.

	  If you have a legacy free Toshiba laptop (such as the Libretto L1
	  series), say Y.

	243	---help---
	244	Overriding LED state on ThinkPads can mask important
	245	firmware alerts (like critical battery condition), or misled
	246	the user into damaging the hardware (undocking or ejecting
	247	the bay while buses are still active), etc.
	248
	249	LED control on the ThinkPad is write-only (with very few
	250	exceptions on very ancient models), which makes it
	251	impossible to know beforehand if important information will
	252	be lost when one changes LED state.
	253
	254	Users that know what they are doing can enable this option
	255	and the driver will allow control of every LED, including
	256	the ones on the dock stations.
	257
	258	Never enable this option on a distribution kernel.
	259
	260	Say N here, unless you are building a kernel for your own

	269	Allows the thinkpad_acpi driver to handle docking station events.
	270	This support was made obsolete by the generic ACPI docking station
	271	support (CONFIG_ACPI_DOCK). It will allow locking and removing the

	294	the various video output ports.
	295
	296	This feature often won't work well, depending on ThinkPad model,
	297	display state, video output devices in use, whether there is a X
	298	server running, phase of the moon, and the current mood of
	299	Schroedinger's cat. If you can use X.org's RandR to control
	300	your ThinkPad's video output ports instead of this feature,
	301	don't think twice: do it and say N here to save some memory.

	307	depends on THINKPAD_ACPI
	308	default y
	309	---help---
	310	Some thinkpad models benefit from NVRAM polling to detect a few of
	311	the hot key press events. If you know your ThinkPad model does not
	312	need to do NVRAM polling to support any of the hot keys you use,
	313	unselecting this option will save about 1kB of memory.
	314
	315	ThinkPads T40 and newer, R52 and newer, and X31 and newer are
	316	unlikely to need NVRAM polling in their latest BIOS versions.
	317
	318	NVRAM polling can detect at most the following keys: ThinkPad/Access
	319	IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
	320	Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

b4f9fe12 LB	353	help
	354	This driver adds support for the ACPI-WMI (Windows Management
	355	Instrumentation) mapper device (PNP0C14) found on some systems.
	356
	357	ACPI-WMI is a proprietary extension to ACPI to expose parts of the
	358	ACPI firmware to userspace - this is done through various vendor
	359	defined methods and data blocks in a PNP0C14 device, which are then
	360	made available for userspace to call.
	361
	362	The implementation of this in Linux currently only exposes this to
	363	other kernel space drivers.
	364
	365	This driver is a required dependency to build the firmware specific
	366	drivers needed on many machines, including Acer and HP laptops.
	367
	368	It is safe to enable this driver even if your DSDT doesn't define
	369	any ACPI-WMI devices.

	376	This driver provides support for extra features of ACPI-compatible
	377	ASUS laptops. As some of Medion laptops are made by ASUS, it may also
	378	support some Medion laptops (such as 9675 for example). It makes all
	379	the extra buttons generate standard ACPI events that go through
	380	/proc/acpi/events, and (on some models) adds support for changing the
	381	display brightness and output, switching the LCD backlight on and off,
	382	and most importantly, allows you to blink those fancy LEDs intended
	383	for reporting mail and wireless status.
	384
	385	Note: display switching code is currently considered EXPERIMENTAL,
	386	toying with these values may even lock your machine.
	387
	388	All settings are changed via /proc/acpi/asus directory entries. Owner
	389	and group for these entries can be set with asus_uid and asus_gid
	390	parameters.
	391
	392	More information and a userspace daemon for handling the extra buttons
	393	at <http://sourceforge.net/projects/acpi4asus/>.

	395	If you have an ACPI-compatible ASUS laptop, say Y or M here. This
	396	driver is still under development, so if your laptop is unsupported or
	397	something works not quite as expected, please use the mailing list
	398	available on the above page (acpi4asus-user@lists.sourceforge.net).
	399
	400	NOTE: This driver is deprecated and will probably be removed soon,
	401	use asus-laptop instead.

	410	---help---
	411	This driver adds support for access to certain system settings
	412	on "legacy free" Toshiba laptops. These laptops can be recognized by
	413	their lack of a BIOS setup menu and APM support.
	414
	415	On these machines, all system configuration is handled through the
	416	ACPI. This driver is required for access to controls not covered
	417	by the general ACPI drivers, such as LCD brightness, video output,
	418	etc.
	419
	420	This driver differs from the non-ACPI Toshiba laptop driver (located
	421	under "Processor type and features") in several aspects.
	422	Configuration is accessed by reading and writing text files in the
	423	/proc tree instead of by program interface to /dev. Furthermore, no
	424	power management functions are exposed, as those are handled by the
	425	general ACPI drivers.
	426
	427	More information about this driver is available at
	428	<http://memebeam.org/toys/ToshibaAcpiDriver>.
	429

	431	series), say Y.
