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

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

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