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

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

616 If you choose to compile this driver as a module the module will be
617 called asus-wireless.
623 This driver adds support for the ACPI-WMI (Windows Management
624 Instrumentation) mapper device (PNP0C14) found on some systems.
626 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
627 ACPI firmware to userspace - this is done through various vendor
628 defined methods and data blocks in a PNP0C14 device, which are then
629 made available for userspace to call.
631 The implementation of this in Linux currently only exposes this to
632 other kernel space drivers.
634 This driver is a required dependency to build the firmware specific
635 drivers needed on many machines, including Acer and HP laptops.

682 On these machines, all system configuration is handled through the
683 ACPI. This driver is required for access to controls not covered
684 by the general ACPI drivers, such as LCD brightness, video output,
687 This driver differs from the non-ACPI Toshiba laptop driver (located
688 under "Processor type and features") in several aspects.
689 Configuration is accessed by reading and writing text files in the
690 /proc tree instead of by program interface to /dev. Furthermore, no
