422 depends on RFKILL || RFKILL = n
423 depends on ACPI_VIDEO || ACPI_VIDEO = n
424 depends on BACKLIGHT_CLASS_DEVICE
430 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
431 support for Fn-Fx key combinations, Bluetooth control, video
432 output switching, ThinkLight control, UltraBay eject and more.
433 For more information about this driver see
434 <file:Documentation/laptops/thinkpad-acpi.txt> and
435 <http://ibm-acpi.sf.net/> .
437 This driver was formerly known as ibm-acpi.
439 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
440 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
441 Note that if you want ThinkPad-ACPI to be built-in instead of
442 modular, ALSA and rfkill will also have to be built-in.
444 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
446 config THINKPAD_ACPI_ALSA_SUPPORT
447 bool "Console audio control ALSA interface"
448 depends on THINKPAD_ACPI
450 depends on SND = y || THINKPAD_ACPI = SND
453 Enables monitoring of the built-in console audio output control
454 (headphone and speakers), which is operated by the mute and (in
455 some ThinkPad models) volume hotkeys.
457 If this option is enabled, ThinkPad-ACPI will export an ALSA card
458 with a single read-only mixer control, which should be used for
459 on-screen-display feedback purposes by the Desktop Environment.
461 Optionally, the driver will also allow software control (the
462 ALSA mixer will be made read-write). Please refer to the driver
463 documentation for details.
465 All IBM models have both volume and mute control. Newer Lenovo
466 models only have mute control (the volume hotkeys are just normal
467 keys and volume control is done through the main HDA mixer).
469 config THINKPAD_ACPI_DEBUGFACILITIES
470 bool "Maintainer debug facilities"
471 depends on THINKPAD_ACPI
473 Enables extra stuff in the thinkpad-acpi which is completely useless

476 Say N here, unless you were told by a kernel maintainer to do
479 config THINKPAD_ACPI_DEBUG
480 bool "Verbose debug mode"
481 depends on THINKPAD_ACPI
483 Enables extra debugging information, at the expense of a slightly
484 increase in driver size.
486 If you are not sure, say N here.
488 config THINKPAD_ACPI_UNSAFE_LEDS
489 bool "Allow control of important LEDs (unsafe)"
490 depends on THINKPAD_ACPI
492 Overriding LED state on ThinkPads can mask important
493 firmware alerts (like critical battery condition), or misled
494 the user into damaging the hardware (undocking or ejecting
495 the bay while buses are still active), etc.
497 LED control on the ThinkPad is write-only (with very few
498 exceptions on very ancient models), which makes it
499 impossible to know beforehand if important information will
500 be lost when one changes LED state.
502 Users that know what they are doing can enable this option
503 and the driver will allow control of every LED, including
504 the ones on the dock stations.
506 Never enable this option on a distribution kernel.
508 Say N here, unless you are building a kernel for your own
509 use, and need to control the important firmware LEDs.
511 config THINKPAD_ACPI_VIDEO
512 bool "Video output control support"
513 depends on THINKPAD_ACPI
516 Allows the thinkpad_acpi driver to provide an interface to control
517 the various video output ports.
519 This feature often won't work well, depending on ThinkPad model,
520 display state, video output devices in use, whether there is a X
521 server running, phase of the moon, and the current mood of
522 Schroedinger's cat. If you can use X.org's RandR to control
523 your ThinkPad's video output ports instead of this feature,
524 don't think twice: do it and say N here to save memory and avoid
525 bad interactions with X.org.
527 NOTE: access to this feature is limited to processes with the
528 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
529 where it interacts badly with X.org.
531 If you are not sure, say Y here but do try to check if you could
532 be using X.org RandR instead.
534 config THINKPAD_ACPI_HOTKEY_POLL
535 bool "Support NVRAM polling for hot keys"
536 depends on THINKPAD_ACPI
539 Some thinkpad models benefit from NVRAM polling to detect a few of
540 the hot key press events. If you know your ThinkPad model does not
541 need to do NVRAM polling to support any of the hot keys you use,
542 unselecting this option will save about 1kB of memory.
544 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
545 unlikely to need NVRAM polling in their latest BIOS versions.
547 NVRAM polling can detect at most the following keys: ThinkPad/Access
548 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
549 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
551 If you are not sure, say Y here. The driver enables polling only if
552 it is strictly necessary to do so.
555 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
559 This driver provides support for the IBM Hard Drive Active Protection
560 System (hdaps), which provides an accelerometer and other misc. data.
561 ThinkPads starting with the R50, T41, and X40 are supported. The
562 accelerometer data is readable via sysfs.
564 This driver also provides an absolute input class device, allowing
565 the laptop to act as a pinball machine-esque joystick.
567 If your ThinkPad is not recognized by the driver, please update to latest
568 BIOS. This is especially the case for some R52 ThinkPads.
570 Say Y here if you have an applicable laptop and want to experience
571 the awesome power of hdaps.

665 called asus-wireless.
671 This driver adds support for the ACPI-WMI (Windows Management
672 Instrumentation) mapper device (PNP0C14) found on some systems.
674 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
675 ACPI firmware to userspace - this is done through various vendor
676 defined methods and data blocks in a PNP0C14 device, which are then
677 made available for userspace to call.
679 The implementation of this in Linux currently only exposes this to
680 other kernel space drivers.
682 This driver is a required dependency to build the firmware specific

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