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

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

612 called asus-wireless.
618 This driver adds support for the ACPI-WMI (Windows Management
619 Instrumentation) mapper device (PNP0C14) found on some systems.
621 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
622 ACPI firmware to userspace - this is done through various vendor
623 defined methods and data blocks in a PNP0C14 device, which are then
624 made available for userspace to call.
626 The implementation of this in Linux currently only exposes this to
627 other kernel space drivers.
629 This driver is a required dependency to build the firmware specific
630 drivers needed on many machines, including Acer and HP laptops.

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