 450           This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
 451           support for Fn-Fx key combinations, Bluetooth control, video
 452           output switching, ThinkLight control, UltraBay eject and more.
 453           For more information about this driver see
 454           <file:Documentation/laptops/thinkpad-acpi.txt> and
 455           <http://ibm-acpi.sf.net/> .
 456
 457           This driver was formerly known as ibm-acpi.
 458
 459           Extra functionality will be available if the rfkill (CONFIG_RFKILL)
 460           and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
 461           Note that if you want ThinkPad-ACPI to be built-in instead of
 462           modular, ALSA and rfkill will also have to be built-in.

 474           (headphone and speakers), which is operated by the mute and (in
 475           some ThinkPad models) volume hotkeys.
 476
 477           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 478           with a single read-only mixer control, which should be used for
 479           on-screen-display feedback purposes by the Desktop Environment.
 480
 481           Optionally, the driver will also allow software control (the
 482           ALSA mixer will be made read-write).  Please refer to the driver
 483           documentation for details.
 484
 485           All IBM models have both volume and mute control.  Newer Lenovo
 486           models only have mute control (the volume hotkeys are just normal
 487           keys and volume control is done through the main HDA mixer).

 512           Overriding LED state on ThinkPads can mask important

 514           the user into damaging the hardware (undocking or ejecting
 515           the bay while buses are still active), etc.
 516
 517           LED control on the ThinkPad is write-only (with very few
 518           exceptions on very ancient models), which makes it
 519           impossible to know beforehand if important information will
 520           be lost when one changes LED state.
 521
 522           Users that know what they are doing can enable this option
 523           and the driver will allow control of every LED, including
 524           the ones on the dock stations.
 525
 526           Never enable this option on a distribution kernel.
 527

 543           your ThinkPad's video output ports instead of this feature,
 544           don't think twice: do it and say N here to save memory and avoid
 545           bad interactions with X.org.
 546
 547           NOTE: access to this feature is limited to processes with the
 548           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 549           where it interacts badly with X.org.

 559           Some thinkpad models benefit from NVRAM polling to detect a few of
 560           the hot key press events.  If you know your ThinkPad model does not
 561           need to do NVRAM polling to support any of the hot keys you use,
 562           unselecting this option will save about 1kB of memory.
 563
 564           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 565           unlikely to need NVRAM polling in their latest BIOS versions.
 566
 567           NVRAM polling can detect at most the following keys: ThinkPad/Access
 568           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 569           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

1188           This driver reads maximum performance ratio of each CPU and set up
1189           the scheduler priority metrics. In this way scheduler can prefer
1190           CPU with higher performance to schedule tasks.
1191           This driver is only required when the system is not using Hardware
1192           P-States (HWP). In HWP mode, priority can be read from ACPI tables.

1198           Certain ACPI based tablets with Silead touchscreens do not have
1199           enough data in ACPI tables for the touchscreen driver to handle
1200           the touchscreen properly, as OEMs expected the data to be baked
1201           into the tablet model specific version of the driver shipped
1202           with the OS-image for the device. This option supplies the missing
1203           information. Enable this for x86 tablets with Silead touchscreens.
