323 depends on RFKILL || RFKILL = n
324 select BACKLIGHT_LCD_SUPPORT

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

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

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

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