403 depends on RFKILL || RFKILL = n
404 depends on ACPI_VIDEO || ACPI_VIDEO = n
405 depends on BACKLIGHT_CLASS_DEVICE
411 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
412 support for Fn-Fx key combinations, Bluetooth control, video
413 output switching, ThinkLight control, UltraBay eject and more.
414 For more information about this driver see
415 <file:Documentation/laptops/thinkpad-acpi.txt> and
416 <http://ibm-acpi.sf.net/> .
418 This driver was formerly known as ibm-acpi.
420 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
421 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
422 Note that if you want ThinkPad-ACPI to be built-in instead of
423 modular, ALSA and rfkill will also have to be built-in.
425 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
427 config THINKPAD_ACPI_ALSA_SUPPORT
428 bool "Console audio control ALSA interface"
429 depends on THINKPAD_ACPI
431 depends on SND = y || THINKPAD_ACPI = SND
434 Enables monitoring of the built-in console audio output control
435 (headphone and speakers), which is operated by the mute and (in
436 some ThinkPad models) volume hotkeys.
438 If this option is enabled, ThinkPad-ACPI will export an ALSA card
439 with a single read-only mixer control, which should be used for
440 on-screen-display feedback purposes by the Desktop Environment.
442 Optionally, the driver will also allow software control (the
443 ALSA mixer will be made read-write). Please refer to the driver
444 documentation for details.
446 All IBM models have both volume and mute control. Newer Lenovo
447 models only have mute control (the volume hotkeys are just normal
448 keys and volume control is done through the main HDA mixer).
450 config THINKPAD_ACPI_DEBUGFACILITIES
451 bool "Maintainer debug facilities"
452 depends on THINKPAD_ACPI
454 Enables extra stuff in the thinkpad-acpi which is completely useless
455 for normal use. Read the driver source to find out what it does.
457 Say N here, unless you were told by a kernel maintainer to do
460 config THINKPAD_ACPI_DEBUG
461 bool "Verbose debug mode"
462 depends on THINKPAD_ACPI
464 Enables extra debugging information, at the expense of a slightly
465 increase in driver size.
467 If you are not sure, say N here.
469 config THINKPAD_ACPI_UNSAFE_LEDS
470 bool "Allow control of important LEDs (unsafe)"
471 depends on THINKPAD_ACPI
473 Overriding LED state on ThinkPads can mask important
474 firmware alerts (like critical battery condition), or misled
475 the user into damaging the hardware (undocking or ejecting
476 the bay while buses are still active), etc.
478 LED control on the ThinkPad is write-only (with very few
479 exceptions on very ancient models), which makes it
480 impossible to know beforehand if important information will
481 be lost when one changes LED state.
483 Users that know what they are doing can enable this option
484 and the driver will allow control of every LED, including
485 the ones on the dock stations.
487 Never enable this option on a distribution kernel.
489 Say N here, unless you are building a kernel for your own
490 use, and need to control the important firmware LEDs.
492 config THINKPAD_ACPI_VIDEO
493 bool "Video output control support"
494 depends on THINKPAD_ACPI
497 Allows the thinkpad_acpi driver to provide an interface to control
498 the various video output ports.
500 This feature often won't work well, depending on ThinkPad model,
501 display state, video output devices in use, whether there is a X
502 server running, phase of the moon, and the current mood of
503 Schroedinger's cat. If you can use X.org's RandR to control
504 your ThinkPad's video output ports instead of this feature,
505 don't think twice: do it and say N here to save memory and avoid
506 bad interactions with X.org.
508 NOTE: access to this feature is limited to processes with the
509 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
510 where it interacts badly with X.org.
512 If you are not sure, say Y here but do try to check if you could
513 be using X.org RandR instead.
515 config THINKPAD_ACPI_HOTKEY_POLL
516 bool "Support NVRAM polling for hot keys"
517 depends on THINKPAD_ACPI
520 Some thinkpad models benefit from NVRAM polling to detect a few of
521 the hot key press events. If you know your ThinkPad model does not
522 need to do NVRAM polling to support any of the hot keys you use,
523 unselecting this option will save about 1kB of memory.
525 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
526 unlikely to need NVRAM polling in their latest BIOS versions.
528 NVRAM polling can detect at most the following keys: ThinkPad/Access
529 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
530 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
532 If you are not sure, say Y here. The driver enables polling only if
533 it is strictly necessary to do so.
536 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
540 This driver provides support for the IBM Hard Drive Active Protection
541 System (hdaps), which provides an accelerometer and other misc. data.
542 ThinkPads starting with the R50, T41, and X40 are supported. The
543 accelerometer data is readable via sysfs.
545 This driver also provides an absolute input class device, allowing
546 the laptop to act as a pinball machine-esque joystick.
548 If your ThinkPad is not recognized by the driver, please update to latest
549 BIOS. This is especially the case for some R52 ThinkPads.
551 Say Y here if you have an applicable laptop and want to experience
552 the awesome power of hdaps.

646 called asus-wireless.
652 This driver adds support for the ACPI-WMI (Windows Management
653 Instrumentation) mapper device (PNP0C14) found on some systems.
655 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
656 ACPI firmware to userspace - this is done through various vendor
657 defined methods and data blocks in a PNP0C14 device, which are then
658 made available for userspace to call.
660 The implementation of this in Linux currently only exposes this to
661 other kernel space drivers.
663 This driver is a required dependency to build the firmware specific

741 their lack of a BIOS setup menu and APM support.
743 On these machines, all system configuration is handled through the
744 ACPI. This driver is required for access to controls not covered
745 by the general ACPI drivers, such as LCD brightness, video output,
748 This driver differs from the non-ACPI Toshiba laptop driver (located
749 under "Processor type and features") in several aspects.
750 Configuration is accessed by reading and writing text files in the
