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

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

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

701 not receive CPU-generated SMIs for recoverable errors. Use of this
702 feature without proper support may void your hardware warranty.
704 If the proper BIOS support is found the driver will load and create
