 411           This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
 412           support for Fn-Fx key combinations, Bluetooth control, video
 413           output switching, ThinkLight control, UltraBay eject and more.
 414           For more information about this driver see
 415           <file:Documentation/laptops/thinkpad-acpi.txt> and
 416           <http://ibm-acpi.sf.net/> .
 417
 418           This driver was formerly known as ibm-acpi.
 419
 420           Extra functionality will be available if the rfkill (CONFIG_RFKILL)
 421           and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
 422           Note that if you want ThinkPad-ACPI to be built-in instead of
 423           modular, ALSA and rfkill will also have to be built-in.
 424
 425           If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
 426
 427 config THINKPAD_ACPI_ALSA_SUPPORT
 428         bool "Console audio control ALSA interface"
 429         depends on THINKPAD_ACPI
 430         depends on SND
 431         depends on SND = y || THINKPAD_ACPI = SND
 432         default y
 433         ---help---
 434           Enables monitoring of the built-in console audio output control
 435           (headphone and speakers), which is operated by the mute and (in
 436           some ThinkPad models) volume hotkeys.
 437
 438           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 439           with a single read-only mixer control, which should be used for
 440           on-screen-display feedback purposes by the Desktop Environment.
 441
 442           Optionally, the driver will also allow software control (the
 443           ALSA mixer will be made read-write).  Please refer to the driver
 444           documentation for details.
 445
 446           All IBM models have both volume and mute control.  Newer Lenovo
 447           models only have mute control (the volume hotkeys are just normal
 448           keys and volume control is done through the main HDA mixer).
 449
 450 config THINKPAD_ACPI_DEBUGFACILITIES
 451         bool "Maintainer debug facilities"
 452         depends on THINKPAD_ACPI
 453         ---help---
 454           Enables extra stuff in the thinkpad-acpi which is completely useless
 455           for normal use.  Read the driver source to find out what it does.
 456
 457           Say N here, unless you were told by a kernel maintainer to do
 458           otherwise.
 459
 460 config THINKPAD_ACPI_DEBUG
 461         bool "Verbose debug mode"
 462         depends on THINKPAD_ACPI
 463         ---help---
 464           Enables extra debugging information, at the expense of a slightly
 465           increase in driver size.
 466
 467           If you are not sure, say N here.
 468
 469 config THINKPAD_ACPI_UNSAFE_LEDS
 470         bool "Allow control of important LEDs (unsafe)"
 471         depends on THINKPAD_ACPI
 472         ---help---
 473           Overriding LED state on ThinkPads can mask important
 474           firmware alerts (like critical battery condition), or misled
 475           the user into damaging the hardware (undocking or ejecting
 476           the bay while buses are still active), etc.
 477
 478           LED control on the ThinkPad is write-only (with very few
 479           exceptions on very ancient models), which makes it
 480           impossible to know beforehand if important information will
 481           be lost when one changes LED state.
 482
 483           Users that know what they are doing can enable this option
 484           and the driver will allow control of every LED, including
 485           the ones on the dock stations.
 486
 487           Never enable this option on a distribution kernel.
 488
 489           Say N here, unless you are building a kernel for your own
 490           use, and need to control the important firmware LEDs.
 491

 498           the various video output ports.
 499
 500           This feature often won't work well, depending on ThinkPad model,
 501           display state, video output devices in use, whether there is a X
 502           server running, phase of the moon, and the current mood of
 503           Schroedinger's cat.  If you can use X.org's RandR to control
 504           your ThinkPad's video output ports instead of this feature,
 505           don't think twice: do it and say N here to save memory and avoid
 506           bad interactions with X.org.
 507
 508           NOTE: access to this feature is limited to processes with the
 509           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 510           where it interacts badly with X.org.
 511
 512           If you are not sure, say Y here but do try to check if you could
 513           be using X.org RandR instead.

 517         depends on THINKPAD_ACPI
 518         default y
 519         ---help---
 520           Some thinkpad models benefit from NVRAM polling to detect a few of
 521           the hot key press events.  If you know your ThinkPad model does not
 522           need to do NVRAM polling to support any of the hot keys you use,
 523           unselecting this option will save about 1kB of memory.
 524
 525           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 526           unlikely to need NVRAM polling in their latest BIOS versions.
 527
 528           NVRAM polling can detect at most the following keys: ThinkPad/Access
 529           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 530           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
 531
 532           If you are not sure, say Y here.  The driver enables polling only if
 533           it is strictly necessary to do so.

 540           This driver provides support for the IBM Hard Drive Active Protection
 541           System (hdaps), which provides an accelerometer and other misc. data.
 542           ThinkPads starting with the R50, T41, and X40 are supported.  The
 543           accelerometer data is readable via sysfs.
 544
 545           This driver also provides an absolute input class device, allowing
 546           the laptop to act as a pinball machine-esque joystick.
 547
 548           If your ThinkPad is not recognized by the driver, please update to latest
 549           BIOS. This is especially the case for some R52 ThinkPads.
 550

 654
 655           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 656           ACPI firmware to userspace - this is done through various vendor
 657           defined methods and data blocks in a PNP0C14 device, which are then
 658           made available for userspace to call.
 659
 660           The implementation of this in Linux currently only exposes this to
 661           other kernel space drivers.
 662
 663           This driver is a required dependency to build the firmware specific
 664           drivers needed on many machines, including Acer and HP laptops.

 750           Configuration is accessed by reading and writing text files in the
