331 depends on RFKILL || RFKILL = n
332 select BACKLIGHT_LCD_SUPPORT
333 select BACKLIGHT_CLASS_DEVICE
339 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
340 support for Fn-Fx key combinations, Bluetooth control, video
341 output switching, ThinkLight control, UltraBay eject and more.
342 For more information about this driver see
343 <file:Documentation/laptops/thinkpad-acpi.txt> and
344 <http://ibm-acpi.sf.net/> .
346 This driver was formerly known as ibm-acpi.
348 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
349 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
350 Note that if you want ThinkPad-ACPI to be built-in instead of
351 modular, ALSA and rfkill will also have to be built-in.
353 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
355 config THINKPAD_ACPI_ALSA_SUPPORT
356 bool "Console audio control ALSA interface"
357 depends on THINKPAD_ACPI
359 depends on SND = y || THINKPAD_ACPI = SND
362 Enables monitoring of the built-in console audio output control
363 (headphone and speakers), which is operated by the mute and (in
364 some ThinkPad models) volume hotkeys.
366 If this option is enabled, ThinkPad-ACPI will export an ALSA card
367 with a single read-only mixer control, which should be used for
368 on-screen-display feedback purposes by the Desktop Environment.
370 Optionally, the driver will also allow software control (the
371 ALSA mixer will be made read-write). Please refer to the driver
372 documentation for details.
374 All IBM models have both volume and mute control. Newer Lenovo
375 models only have mute control (the volume hotkeys are just normal
376 keys and volume control is done through the main HDA mixer).
378 config THINKPAD_ACPI_DEBUGFACILITIES
379 bool "Maintainer debug facilities"
380 depends on THINKPAD_ACPI
383 Enables extra stuff in the thinkpad-acpi which is completely useless
384 for normal use. Read the driver source to find out what it does.
386 Say N here, unless you were told by a kernel maintainer to do
389 config THINKPAD_ACPI_DEBUG
390 bool "Verbose debug mode"
391 depends on THINKPAD_ACPI
394 Enables extra debugging information, at the expense of a slightly
395 increase in driver size.
397 If you are not sure, say N here.
399 config THINKPAD_ACPI_UNSAFE_LEDS
400 bool "Allow control of important LEDs (unsafe)"
401 depends on THINKPAD_ACPI
404 Overriding LED state on ThinkPads can mask important
405 firmware alerts (like critical battery condition), or misled
406 the user into damaging the hardware (undocking or ejecting
407 the bay while buses are still active), etc.
409 LED control on the ThinkPad is write-only (with very few
410 exceptions on very ancient models), which makes it
411 impossible to know beforehand if important information will
412 be lost when one changes LED state.
414 Users that know what they are doing can enable this option
415 and the driver will allow control of every LED, including
416 the ones on the dock stations.
418 Never enable this option on a distribution kernel.
420 Say N here, unless you are building a kernel for your own
421 use, and need to control the important firmware LEDs.
423 config THINKPAD_ACPI_VIDEO
424 bool "Video output control support"
425 depends on THINKPAD_ACPI
428 Allows the thinkpad_acpi driver to provide an interface to control
429 the various video output ports.
431 This feature often won't work well, depending on ThinkPad model,
432 display state, video output devices in use, whether there is a X
433 server running, phase of the moon, and the current mood of
434 Schroedinger's cat. If you can use X.org's RandR to control
435 your ThinkPad's video output ports instead of this feature,
436 don't think twice: do it and say N here to save memory and avoid
437 bad interactions with X.org.
439 NOTE: access to this feature is limited to processes with the
440 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
441 where it interacts badly with X.org.
443 If you are not sure, say Y here but do try to check if you could
444 be using X.org RandR instead.
446 config THINKPAD_ACPI_HOTKEY_POLL
447 bool "Support NVRAM polling for hot keys"
448 depends on THINKPAD_ACPI
451 Some thinkpad models benefit from NVRAM polling to detect a few of
452 the hot key press events. If you know your ThinkPad model does not
453 need to do NVRAM polling to support any of the hot keys you use,
454 unselecting this option will save about 1kB of memory.
456 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
457 unlikely to need NVRAM polling in their latest BIOS versions.
459 NVRAM polling can detect at most the following keys: ThinkPad/Access
460 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
461 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
463 If you are not sure, say Y here. The driver enables polling only if
464 it is strictly necessary to do so.
467 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
468 depends on INPUT && X86
472 This driver provides support for the IBM Hard Drive Active Protection
473 System (hdaps), which provides an accelerometer and other misc. data.
474 ThinkPads starting with the R50, T41, and X40 are supported. The
475 accelerometer data is readable via sysfs.
477 This driver also provides an absolute input class device, allowing
478 the laptop to act as a pinball machine-esque joystick.
480 If your ThinkPad is not recognized by the driver, please update to latest
481 BIOS. This is especially the case for some R52 ThinkPads.
483 Say Y here if you have an applicable laptop and want to experience
484 the awesome power of hdaps.

559 If you have an ACPI-WMI compatible Eee PC laptop (>= 1000), say Y or M
566 This driver adds support for the ACPI-WMI (Windows Management
567 Instrumentation) mapper device (PNP0C14) found on some systems.
569 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
570 ACPI firmware to userspace - this is done through various vendor
571 defined methods and data blocks in a PNP0C14 device, which are then
572 made available for userspace to call.
574 The implementation of this in Linux currently only exposes this to
575 other kernel space drivers.
577 This driver is a required dependency to build the firmware specific
578 drivers needed on many machines, including Acer and HP laptops.
580 It is safe to enable this driver even if your DSDT doesn't define
581 any ACPI-WMI devices.

618 This driver adds support for access to certain system settings
619 on "legacy free" Toshiba laptops. These laptops can be recognized by
620 their lack of a BIOS setup menu and APM support.
622 On these machines, all system configuration is handled through the
623 ACPI. This driver is required for access to controls not covered
624 by the general ACPI drivers, such as LCD brightness, video output,
627 This driver differs from the non-ACPI Toshiba laptop driver (located
628 under "Processor type and features") in several aspects.
629 Configuration is accessed by reading and writing text files in the
630 /proc tree instead of by program interface to /dev. Furthermore, no
631 power management functions are exposed, as those are handled by the
632 general ACPI drivers.
