384 depends on RFKILL || RFKILL = n

392 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds

394 output switching, ThinkLight control, UltraBay eject and more.
395 For more information about this driver see
396 <file:Documentation/laptops/thinkpad-acpi.txt> and
397 <http://ibm-acpi.sf.net/> .
399 This driver was formerly known as ibm-acpi.
401 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
402 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
403 Note that if you want ThinkPad-ACPI to be built-in instead of
404 modular, ALSA and rfkill will also have to be built-in.
406 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
408 config THINKPAD_ACPI_ALSA_SUPPORT
409 bool "Console audio control ALSA interface"
410 depends on THINKPAD_ACPI
412 depends on SND = y || THINKPAD_ACPI = SND
415 Enables monitoring of the built-in console audio output control
416 (headphone and speakers), which is operated by the mute and (in
417 some ThinkPad models) volume hotkeys.
419 If this option is enabled, ThinkPad-ACPI will export an ALSA card
420 with a single read-only mixer control, which should be used for
421 on-screen-display feedback purposes by the Desktop Environment.
423 Optionally, the driver will also allow software control (the
424 ALSA mixer will be made read-write). Please refer to the driver
425 documentation for details.
427 All IBM models have both volume and mute control. Newer Lenovo
428 models only have mute control (the volume hotkeys are just normal
429 keys and volume control is done through the main HDA mixer).
431 config THINKPAD_ACPI_DEBUGFACILITIES

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

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

736 Configuration is accessed by reading and writing text files in the
