 425           This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
 426           support for Fn-Fx key combinations, Bluetooth control, video
 427           output switching, ThinkLight control, UltraBay eject and more.
 428           For more information about this driver see
 429           <file:Documentation/laptops/thinkpad-acpi.txt> and
 430           <http://ibm-acpi.sf.net/> .
 431
 432           This driver was formerly known as ibm-acpi.
 433
 434           Extra functionality will be available if the rfkill (CONFIG_RFKILL)
 435           and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
 436           Note that if you want ThinkPad-ACPI to be built-in instead of
 437           modular, ALSA and rfkill will also have to be built-in.
 438
 439           If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.

 448           Enables monitoring of the built-in console audio output control
 449           (headphone and speakers), which is operated by the mute and (in
 450           some ThinkPad models) volume hotkeys.
 451
 452           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 453           with a single read-only mixer control, which should be used for
 454           on-screen-display feedback purposes by the Desktop Environment.
 455
 456           Optionally, the driver will also allow software control (the
 457           ALSA mixer will be made read-write).  Please refer to the driver
 458           documentation for details.
 459
 460           All IBM models have both volume and mute control.  Newer Lenovo
 461           models only have mute control (the volume hotkeys are just normal
 462           keys and volume control is done through the main HDA mixer).

 486         ---help---
 487           Overriding LED state on ThinkPads can mask important
 488           firmware alerts (like critical battery condition), or misled
 489           the user into damaging the hardware (undocking or ejecting
 490           the bay while buses are still active), etc.
 491
 492           LED control on the ThinkPad is write-only (with very few
 493           exceptions on very ancient models), which makes it
 494           impossible to know beforehand if important information will
 495           be lost when one changes LED state.
 496
 497           Users that know what they are doing can enable this option
 498           and the driver will allow control of every LED, including
 499           the ones on the dock stations.
 500
 501           Never enable this option on a distribution kernel.
 502
 503           Say N here, unless you are building a kernel for your own
 504           use, and need to control the important firmware LEDs.

 515           display state, video output devices in use, whether there is a X
 516           server running, phase of the moon, and the current mood of
 517           Schroedinger's cat.  If you can use X.org's RandR to control
 518           your ThinkPad's video output ports instead of this feature,
 519           don't think twice: do it and say N here to save memory and avoid
 520           bad interactions with X.org.
 521
 522           NOTE: access to this feature is limited to processes with the
 523           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 524           where it interacts badly with X.org.
 525
 526           If you are not sure, say Y here but do try to check if you could
 527           be using X.org RandR instead.

 534           Some thinkpad models benefit from NVRAM polling to detect a few of
 535           the hot key press events.  If you know your ThinkPad model does not
 536           need to do NVRAM polling to support any of the hot keys you use,
 537           unselecting this option will save about 1kB of memory.
 538
 539           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 540           unlikely to need NVRAM polling in their latest BIOS versions.
 541
 542           NVRAM polling can detect at most the following keys: ThinkPad/Access
 543           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 544           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 668
 669           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 670           ACPI firmware to userspace - this is done through various vendor
 671           defined methods and data blocks in a PNP0C14 device, which are then
 672           made available for userspace to call.

1180           Certain ACPI based tablets with Silead touchscreens do not have
1181           enough data in ACPI tables for the touchscreen driver to handle
1182           the touchscreen properly, as OEMs expected the data to be baked
1183           into the tablet model specific version of the driver shipped
1184           with the OS-image for the device. This option supplies the missing
1185           information. Enable this for x86 tablets with Silead touchscreens.
