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

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

748 their lack of a BIOS setup menu and APM support.
750 On these machines, all system configuration is handled through the
751 ACPI. This driver is required for access to controls not covered
752 by the general ACPI drivers, such as LCD brightness, video output,
755 This driver differs from the non-ACPI Toshiba laptop driver (located
756 under "Processor type and features") in several aspects.
757 Configuration is accessed by reading and writing text files in the
758 /proc tree instead of by program interface to /dev. Furthermore, no
