379 depends on RFKILL || RFKILL = n
380 depends on ACPI_VIDEO || ACPI_VIDEO = n
381 depends on BACKLIGHT_CLASS_DEVICE
387 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
388 support for Fn-Fx key combinations, Bluetooth control, video
389 output switching, ThinkLight control, UltraBay eject and more.
390 For more information about this driver see
391 <file:Documentation/laptops/thinkpad-acpi.txt> and
392 <http://ibm-acpi.sf.net/> .
394 This driver was formerly known as ibm-acpi.
396 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
397 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
398 Note that if you want ThinkPad-ACPI to be built-in instead of
399 modular, ALSA and rfkill will also have to be built-in.
401 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
403 config THINKPAD_ACPI_ALSA_SUPPORT
404 bool "Console audio control ALSA interface"
405 depends on THINKPAD_ACPI
407 depends on SND = y || THINKPAD_ACPI = SND
410 Enables monitoring of the built-in console audio output control
411 (headphone and speakers), which is operated by the mute and (in
412 some ThinkPad models) volume hotkeys.
414 If this option is enabled, ThinkPad-ACPI will export an ALSA card
415 with a single read-only mixer control, which should be used for
416 on-screen-display feedback purposes by the Desktop Environment.
418 Optionally, the driver will also allow software control (the
419 ALSA mixer will be made read-write). Please refer to the driver
420 documentation for details.
422 All IBM models have both volume and mute control. Newer Lenovo
423 models only have mute control (the volume hotkeys are just normal
424 keys and volume control is done through the main HDA mixer).

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

632 This driver adds support for the ACPI-WMI (Windows Management
633 Instrumentation) mapper device (PNP0C14) found on some systems.
635 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
636 ACPI firmware to userspace - this is done through various vendor
637 defined methods and data blocks in a PNP0C14 device, which are then
638 made available for userspace to call.
640 The implementation of this in Linux currently only exposes this to
641 other kernel space drivers.
643 This driver is a required dependency to build the firmware specific

709 their lack of a BIOS setup menu and APM support.
711 On these machines, all system configuration is handled through the
712 ACPI. This driver is required for access to controls not covered
713 by the general ACPI drivers, such as LCD brightness, video output,
716 This driver differs from the non-ACPI Toshiba laptop driver (located
