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

524 <file:Documentation/ABI/testing/sysfs-platform-asus-wmi>
526 If you have an ACPI-WMI compatible Eee PC laptop (>= 1000), say Y or M
533 This driver adds support for the ACPI-WMI (Windows Management
534 Instrumentation) mapper device (PNP0C14) found on some systems.
536 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
537 ACPI firmware to userspace - this is done through various vendor
538 defined methods and data blocks in a PNP0C14 device, which are then
539 made available for userspace to call.
541 The implementation of this in Linux currently only exposes this to
542 other kernel space drivers.
544 This driver is a required dependency to build the firmware specific
545 drivers needed on many machines, including Acer and HP laptops.
547 It is safe to enable this driver even if your DSDT doesn't define
548 any ACPI-WMI devices.

578 depends on BACKLIGHT_CLASS_DEVICE
580 depends on RFKILL || RFKILL = n
582 select INPUT_SPARSEKMAP
584 This driver adds support for access to certain system settings
585 on "legacy free" Toshiba laptops. These laptops can be recognized by
586 their lack of a BIOS setup menu and APM support.
588 On these machines, all system configuration is handled through the
589 ACPI. This driver is required for access to controls not covered
590 by the general ACPI drivers, such as LCD brightness, video output,
593 This driver differs from the non-ACPI Toshiba laptop driver (located
594 under "Processor type and features") in several aspects.
595 Configuration is accessed by reading and writing text files in the
596 /proc tree instead of by program interface to /dev. Furthermore, no
597 power management functions are exposed, as those are handled by the
598 general ACPI drivers.

691 feature without proper support may void your hardware warranty.
693 If the proper BIOS support is found the driver will load and create
