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

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

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

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