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

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

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

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