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

429 config THINKPAD_ACPI_DEBUG
430 bool "Verbose debug mode"
431 depends on THINKPAD_ACPI
434 Enables extra debugging information, at the expense of a slightly
435 increase in driver size.
437 If you are not sure, say N here.
439 config THINKPAD_ACPI_UNSAFE_LEDS
440 bool "Allow control of important LEDs (unsafe)"
441 depends on THINKPAD_ACPI
444 Overriding LED state on ThinkPads can mask important
445 firmware alerts (like critical battery condition), or misled
446 the user into damaging the hardware (undocking or ejecting
447 the bay while buses are still active), etc.
449 LED control on the ThinkPad is write-only (with very few
450 exceptions on very ancient models), which makes it
451 impossible to know beforehand if important information will
452 be lost when one changes LED state.
454 Users that know what they are doing can enable this option
455 and the driver will allow control of every LED, including
456 the ones on the dock stations.
458 Never enable this option on a distribution kernel.
460 Say N here, unless you are building a kernel for your own
461 use, and need to control the important firmware LEDs.
463 config THINKPAD_ACPI_VIDEO
464 bool "Video output control support"
465 depends on THINKPAD_ACPI
468 Allows the thinkpad_acpi driver to provide an interface to control
469 the various video output ports.
471 This feature often won't work well, depending on ThinkPad model,
472 display state, video output devices in use, whether there is a X
473 server running, phase of the moon, and the current mood of
474 Schroedinger's cat. If you can use X.org's RandR to control
475 your ThinkPad's video output ports instead of this feature,
476 don't think twice: do it and say N here to save memory and avoid
477 bad interactions with X.org.
479 NOTE: access to this feature is limited to processes with the
480 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
481 where it interacts badly with X.org.
483 If you are not sure, say Y here but do try to check if you could
484 be using X.org RandR instead.
486 config THINKPAD_ACPI_HOTKEY_POLL
487 bool "Support NVRAM polling for hot keys"
488 depends on THINKPAD_ACPI
491 Some thinkpad models benefit from NVRAM polling to detect a few of
492 the hot key press events. If you know your ThinkPad model does not
493 need to do NVRAM polling to support any of the hot keys you use,
494 unselecting this option will save about 1kB of memory.
496 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
497 unlikely to need NVRAM polling in their latest BIOS versions.
499 NVRAM polling can detect at most the following keys: ThinkPad/Access
500 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
501 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
503 If you are not sure, say Y here. The driver enables polling only if
504 it is strictly necessary to do so.
507 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
508 depends on INPUT && X86
512 This driver provides support for the IBM Hard Drive Active Protection
513 System (hdaps), which provides an accelerometer and other misc. data.
514 ThinkPads starting with the R50, T41, and X40 are supported. The
515 accelerometer data is readable via sysfs.
517 This driver also provides an absolute input class device, allowing
518 the laptop to act as a pinball machine-esque joystick.
520 If your ThinkPad is not recognized by the driver, please update to latest
521 BIOS. This is especially the case for some R52 ThinkPads.
523 Say Y here if you have an applicable laptop and want to experience
524 the awesome power of hdaps.

614 If you choose to compile this driver as a module the module will be
615 called asus-wireless.
621 This driver adds support for the ACPI-WMI (Windows Management
622 Instrumentation) mapper device (PNP0C14) found on some systems.
624 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
625 ACPI firmware to userspace - this is done through various vendor
626 defined methods and data blocks in a PNP0C14 device, which are then
627 made available for userspace to call.
629 The implementation of this in Linux currently only exposes this to
630 other kernel space drivers.
632 This driver is a required dependency to build the firmware specific
633 drivers needed on many machines, including Acer and HP laptops.
635 It is safe to enable this driver even if your DSDT doesn't define

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