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

504 like wireless radio and bluetooth control, leds, hotkeys, backlight...
506 For more informations, see
507 <file:Documentation/ABI/testing/sysfs-platform-asus-wmi>
509 If you have an ACPI-WMI compatible Eee PC laptop (>= 1000), say Y or M
516 This driver adds support for the ACPI-WMI (Windows Management
517 Instrumentation) mapper device (PNP0C14) found on some systems.
519 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
520 ACPI firmware to userspace - this is done through various vendor
521 defined methods and data blocks in a PNP0C14 device, which are then
522 made available for userspace to call.
524 The implementation of this in Linux currently only exposes this to
525 other kernel space drivers.
527 This driver is a required dependency to build the firmware specific
528 drivers needed on many machines, including Acer and HP laptops.
530 It is safe to enable this driver even if your DSDT doesn't define
531 any ACPI-WMI devices.
534 tristate "MSI WMI extras"
537 depends on BACKLIGHT_CLASS_DEVICE
538 select INPUT_SPARSEKMAP
540 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
542 To compile this driver as a module, choose M here: the module will
546 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
548 select BACKLIGHT_CLASS_DEVICE
550 This driver provides support for extra features of ACPI-compatible
551 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
552 support some Medion laptops (such as 9675 for example). It makes all
553 the extra buttons generate standard ACPI events that go through
554 /proc/acpi/events, and (on some models) adds support for changing the
555 display brightness and output, switching the LCD backlight on and off,
556 and most importantly, allows you to blink those fancy LEDs intended
557 for reporting mail and wireless status.
559 Note: display switching code is currently considered EXPERIMENTAL,
560 toying with these values may even lock your machine.
562 All settings are changed via /proc/acpi/asus directory entries. Owner
563 and group for these entries can be set with asus_uid and asus_gid
566 More information and a userspace daemon for handling the extra buttons
567 at <http://acpi4asus.sf.net>.
569 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
570 driver is still under development, so if your laptop is unsupported or
571 something works not quite as expected, please use the mailing list
572 available on the above page (acpi4asus-user@lists.sourceforge.net).
574 NOTE: This driver is deprecated and will probably be removed soon,
575 use asus-laptop instead.
577 config TOPSTAR_LAPTOP
578 tristate "Topstar Laptop Extras"
581 select INPUT_SPARSEKMAP
583 This driver adds support for hotkeys found on Topstar laptops.
585 If you have a Topstar laptop, say Y or M here.
588 tristate "Toshiba Laptop Extras"
592 depends on BACKLIGHT_CLASS_DEVICE
594 depends on RFKILL || RFKILL = n
596 select INPUT_SPARSEKMAP
598 This driver adds support for access to certain system settings
599 on "legacy free" Toshiba laptops. These laptops can be recognized by
600 their lack of a BIOS setup menu and APM support.
602 On these machines, all system configuration is handled through the
603 ACPI. This driver is required for access to controls not covered
604 by the general ACPI drivers, such as LCD brightness, video output,
607 This driver differs from the non-ACPI Toshiba laptop driver (located
608 under "Processor type and features") in several aspects.
609 Configuration is accessed by reading and writing text files in the
610 /proc tree instead of by program interface to /dev. Furthermore, no
611 power management functions are exposed, as those are handled by the
612 general ACPI drivers.
614 More information about this driver is available at

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

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