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

497 like wireless radio and bluetooth control, leds, hotkeys, backlight...
499 For more informations, see
500 <file:Documentation/ABI/testing/sysfs-platform-asus-wmi>
502 If you have an ACPI-WMI compatible Eee PC laptop (>= 1000), say Y or M
509 This driver adds support for the ACPI-WMI (Windows Management
510 Instrumentation) mapper device (PNP0C14) found on some systems.
512 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
513 ACPI firmware to userspace - this is done through various vendor
514 defined methods and data blocks in a PNP0C14 device, which are then
515 made available for userspace to call.
517 The implementation of this in Linux currently only exposes this to
518 other kernel space drivers.
520 This driver is a required dependency to build the firmware specific
521 drivers needed on many machines, including Acer and HP laptops.
523 It is safe to enable this driver even if your DSDT doesn't define
524 any ACPI-WMI devices.
527 tristate "MSI WMI extras"
530 depends on BACKLIGHT_CLASS_DEVICE
531 select INPUT_SPARSEKMAP
533 Say Y here if you want to support WMI-based hotkeys on MSI laptops.

539 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
541 select BACKLIGHT_CLASS_DEVICE
543 This driver provides support for extra features of ACPI-compatible
544 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
545 support some Medion laptops (such as 9675 for example). It makes all
546 the extra buttons generate standard ACPI events that go through
547 /proc/acpi/events, and (on some models) adds support for changing the
548 display brightness and output, switching the LCD backlight on and off,
549 and most importantly, allows you to blink those fancy LEDs intended
550 for reporting mail and wireless status.
552 Note: display switching code is currently considered EXPERIMENTAL,
553 toying with these values may even lock your machine.
555 All settings are changed via /proc/acpi/asus directory entries. Owner
556 and group for these entries can be set with asus_uid and asus_gid
559 More information and a userspace daemon for handling the extra buttons
560 at <http://acpi4asus.sf.net>.
562 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
563 driver is still under development, so if your laptop is unsupported or
564 something works not quite as expected, please use the mailing list
565 available on the above page (acpi4asus-user@lists.sourceforge.net).
567 NOTE: This driver is deprecated and will probably be removed soon,
568 use asus-laptop instead.

571 tristate "Topstar Laptop Extras"
574 select INPUT_SPARSEKMAP
576 This driver adds support for hotkeys found on Topstar laptops.
578 If you have a Topstar laptop, say Y or M here.
581 tristate "Toshiba Laptop Extras"
585 depends on BACKLIGHT_CLASS_DEVICE
587 depends on RFKILL || RFKILL = n
589 select INPUT_SPARSEKMAP
591 This driver adds support for access to certain system settings
592 on "legacy free" Toshiba laptops. These laptops can be recognized by
593 their lack of a BIOS setup menu and APM support.
595 On these machines, all system configuration is handled through the
596 ACPI. This driver is required for access to controls not covered
597 by the general ACPI drivers, such as LCD brightness, video output,
600 This driver differs from the non-ACPI Toshiba laptop driver (located
601 under "Processor type and features") in several aspects.
602 Configuration is accessed by reading and writing text files in the
603 /proc tree instead of by program interface to /dev. Furthermore, no
604 power management functions are exposed, as those are handled by the
605 general ACPI drivers.
607 More information about this driver is available at

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