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

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

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