259 config IDEAPAD_LAPTOP
260 tristate "Lenovo IdeaPad Laptop Extras"
262 depends on RFKILL && INPUT
263 select INPUT_SPARSEKMAP
265 This is a driver for the rfkill switches on Lenovo IdeaPad netbooks.
268 tristate "ThinkPad ACPI Laptop Extras"
271 depends on RFKILL || RFKILL = n
272 select BACKLIGHT_LCD_SUPPORT
273 select BACKLIGHT_CLASS_DEVICE
279 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
280 support for Fn-Fx key combinations, Bluetooth control, video
281 output switching, ThinkLight control, UltraBay eject and more.
282 For more information about this driver see
283 <file:Documentation/laptops/thinkpad-acpi.txt> and
284 <http://ibm-acpi.sf.net/> .
286 This driver was formerly known as ibm-acpi.
288 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
289 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
290 Note that if you want ThinkPad-ACPI to be built-in instead of
291 modular, ALSA and rfkill will also have to be built-in.
293 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
295 config THINKPAD_ACPI_ALSA_SUPPORT
296 bool "Console audio control ALSA interface"
297 depends on THINKPAD_ACPI
299 depends on SND = y || THINKPAD_ACPI = SND
302 Enables monitoring of the built-in console audio output control
303 (headphone and speakers), which is operated by the mute and (in
304 some ThinkPad models) volume hotkeys.
306 If this option is enabled, ThinkPad-ACPI will export an ALSA card
307 with a single read-only mixer control, which should be used for
308 on-screen-display feedback purposes by the Desktop Environment.
310 Optionally, the driver will also allow software control (the
311 ALSA mixer will be made read-write). Please refer to the driver
312 documentation for details.
314 All IBM models have both volume and mute control. Newer Lenovo
315 models only have mute control (the volume hotkeys are just normal
316 keys and volume control is done through the main HDA mixer).
318 config THINKPAD_ACPI_DEBUGFACILITIES
319 bool "Maintainer debug facilities"
320 depends on THINKPAD_ACPI
323 Enables extra stuff in the thinkpad-acpi which is completely useless
324 for normal use. Read the driver source to find out what it does.
326 Say N here, unless you were told by a kernel maintainer to do
329 config THINKPAD_ACPI_DEBUG
330 bool "Verbose debug mode"
331 depends on THINKPAD_ACPI
334 Enables extra debugging information, at the expense of a slightly
335 increase in driver size.
337 If you are not sure, say N here.
339 config THINKPAD_ACPI_UNSAFE_LEDS
340 bool "Allow control of important LEDs (unsafe)"
341 depends on THINKPAD_ACPI
344 Overriding LED state on ThinkPads can mask important
345 firmware alerts (like critical battery condition), or misled
346 the user into damaging the hardware (undocking or ejecting
347 the bay while buses are still active), etc.
349 LED control on the ThinkPad is write-only (with very few
350 exceptions on very ancient models), which makes it
351 impossible to know beforehand if important information will
352 be lost when one changes LED state.
354 Users that know what they are doing can enable this option
355 and the driver will allow control of every LED, including
356 the ones on the dock stations.
358 Never enable this option on a distribution kernel.
360 Say N here, unless you are building a kernel for your own
361 use, and need to control the important firmware LEDs.
363 config THINKPAD_ACPI_VIDEO
364 bool "Video output control support"
365 depends on THINKPAD_ACPI
368 Allows the thinkpad_acpi driver to provide an interface to control
369 the various video output ports.
371 This feature often won't work well, depending on ThinkPad model,
372 display state, video output devices in use, whether there is a X
373 server running, phase of the moon, and the current mood of
374 Schroedinger's cat. If you can use X.org's RandR to control
375 your ThinkPad's video output ports instead of this feature,
376 don't think twice: do it and say N here to save memory and avoid
377 bad interactions with X.org.
379 NOTE: access to this feature is limited to processes with the
380 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
381 where it interacts badly with X.org.
383 If you are not sure, say Y here but do try to check if you could
384 be using X.org RandR instead.
386 config THINKPAD_ACPI_HOTKEY_POLL
387 bool "Support NVRAM polling for hot keys"
388 depends on THINKPAD_ACPI
391 Some thinkpad models benefit from NVRAM polling to detect a few of
392 the hot key press events. If you know your ThinkPad model does not
393 need to do NVRAM polling to support any of the hot keys you use,
394 unselecting this option will save about 1kB of memory.
396 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
397 unlikely to need NVRAM polling in their latest BIOS versions.
399 NVRAM polling can detect at most the following keys: ThinkPad/Access
400 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
401 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
403 If you are not sure, say Y here. The driver enables polling only if
404 it is strictly necessary to do so.
407 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
408 depends on INPUT && X86
412 This driver provides support for the IBM Hard Drive Active Protection
413 System (hdaps), which provides an accelerometer and other misc. data.
414 ThinkPads starting with the R50, T41, and X40 are supported. The
415 accelerometer data is readable via sysfs.
417 This driver also provides an absolute input class device, allowing
418 the laptop to act as a pinball machine-esque joystick.
420 If your ThinkPad is not recognized by the driver, please update to latest
421 BIOS. This is especially the case for some R52 ThinkPads.
423 Say Y here if you have an applicable laptop and want to experience
424 the awesome power of hdaps.
427 tristate "Thermal Management driver for Intel menlow platform"
428 depends on ACPI_THERMAL
431 ACPI thermal management enhancement driver on

498 <file:Documentation/ABI/testing/sysfs-platform-asus-wmi>
500 If you have an ACPI-WMI compatible Eee PC laptop (>= 1000), say Y or M
507 This driver adds support for the ACPI-WMI (Windows Management
508 Instrumentation) mapper device (PNP0C14) found on some systems.
510 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
511 ACPI firmware to userspace - this is done through various vendor
512 defined methods and data blocks in a PNP0C14 device, which are then
513 made available for userspace to call.
515 The implementation of this in Linux currently only exposes this to
516 other kernel space drivers.
518 This driver is a required dependency to build the firmware specific
519 drivers needed on many machines, including Acer and HP laptops.
521 It is safe to enable this driver even if your DSDT doesn't define
522 any ACPI-WMI devices.
525 tristate "MSI WMI extras"
528 depends on BACKLIGHT_CLASS_DEVICE
529 select INPUT_SPARSEKMAP

533 To compile this driver as a module, choose M here: the module will
537 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
539 select BACKLIGHT_CLASS_DEVICE
541 This driver provides support for extra features of ACPI-compatible
542 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
543 support some Medion laptops (such as 9675 for example). It makes all
544 the extra buttons generate standard ACPI events that go through
545 /proc/acpi/events, and (on some models) adds support for changing the
546 display brightness and output, switching the LCD backlight on and off,
547 and most importantly, allows you to blink those fancy LEDs intended
548 for reporting mail and wireless status.
550 Note: display switching code is currently considered EXPERIMENTAL,
551 toying with these values may even lock your machine.
553 All settings are changed via /proc/acpi/asus directory entries. Owner
554 and group for these entries can be set with asus_uid and asus_gid
557 More information and a userspace daemon for handling the extra buttons
558 at <http://acpi4asus.sf.net>.
560 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
561 driver is still under development, so if your laptop is unsupported or
562 something works not quite as expected, please use the mailing list
563 available on the above page (acpi4asus-user@lists.sourceforge.net).
565 NOTE: This driver is deprecated and will probably be removed soon,
566 use asus-laptop instead.
568 config TOPSTAR_LAPTOP
569 tristate "Topstar Laptop Extras"
572 select INPUT_SPARSEKMAP
574 This driver adds support for hotkeys found on Topstar laptops.
576 If you have a Topstar laptop, say Y or M here.
579 tristate "Toshiba Laptop Extras"
583 depends on BACKLIGHT_CLASS_DEVICE
585 depends on RFKILL || RFKILL = n
587 select INPUT_SPARSEKMAP
589 This driver adds support for access to certain system settings
590 on "legacy free" Toshiba laptops. These laptops can be recognized by
591 their lack of a BIOS setup menu and APM support.
593 On these machines, all system configuration is handled through the
594 ACPI. This driver is required for access to controls not covered
595 by the general ACPI drivers, such as LCD brightness, video output,
598 This driver differs from the non-ACPI Toshiba laptop driver (located
599 under "Processor type and features") in several aspects.
600 Configuration is accessed by reading and writing text files in the
601 /proc tree instead of by program interface to /dev. Furthermore, no
602 power management functions are exposed, as those are handled by the
603 general ACPI drivers.
605 More information about this driver is available at

680 depends on PCI && X86_MRST
683 This driver allows other kernel drivers access to the
684 contents of the restricted access region control registers.
686 The restricted access region control registers
687 (rar_registers) are used to pass address and
688 locking information on restricted access regions
689 to other drivers that use restricted access regions.
691 The restricted access regions are regions of memory
692 on the Intel MID Platform that are not accessible to
693 the x86 processor, but are accessible to dedicated
694 processors on board peripheral devices.
696 The purpose of the restricted access regions is to
697 protect sensitive data from compromise by unauthorized
698 programs running on the x86 processor.
701 tristate "Intel Intelligent Power Sharing"
704 Intel Calpella platforms support dynamic power sharing between the
705 CPU and GPU, maximizing performance in a given TDP. This driver,

715 This module will allow you the enter and exit PRTM in the BIOS via
716 sysfs on platforms that support this feature. System in PRTM will
717 not receive CPU-generated SMIs for recoverable errors. Use of this
718 feature without proper support may void your hardware warranty.
720 If the proper BIOS support is found the driver will load and create
721 /sys/devices/system/ibm_rtl/. The "state" variable will indicate
722 whether or not the BIOS is in PRTM.
