 330           Extra functionality will be available if the rfkill (CONFIG_RFKILL)
 331           and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
 332           Note that if you want ThinkPad-ACPI to be built-in instead of
 333           modular, ALSA and rfkill will also have to be built-in.

 347
 348           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 349           with a single read-only mixer control, which should be used for
 350           on-screen-display feedback purposes by the Desktop Environment.
 351
 352           Optionally, the driver will also allow software control (the
 353           ALSA mixer will be made read-write).  Please refer to the driver
 354           documentation for details.
 355
 356           All IBM models have both volume and mute control.  Newer Lenovo
 357           models only have mute control (the volume hotkeys are just normal

 389           the bay while buses are still active), etc.
 390
 391           LED control on the ThinkPad is write-only (with very few
 392           exceptions on very ancient models), which makes it
 393           impossible to know beforehand if important information will
 394           be lost when one changes LED state.
 395
 396           Users that know what they are doing can enable this option
 397           and the driver will allow control of every LED, including
 398           the ones on the dock stations.
 399
 400           Never enable this option on a distribution kernel.

 411           the various video output ports.

 413           This feature often won't work well, depending on ThinkPad model,
 414           display state, video output devices in use, whether there is a X
 415           server running, phase of the moon, and the current mood of
 416           Schroedinger's cat.  If you can use X.org's RandR to control
 417           your ThinkPad's video output ports instead of this feature,
 418           don't think twice: do it and say N here to save memory and avoid
 419           bad interactions with X.org.
 420
 421           NOTE: access to this feature is limited to processes with the
 422           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 423           where it interacts badly with X.org.

 433           Some thinkpad models benefit from NVRAM polling to detect a few of
 434           the hot key press events.  If you know your ThinkPad model does not
 435           need to do NVRAM polling to support any of the hot keys you use,
 436           unselecting this option will save about 1kB of memory.
 437
 438           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 439           unlikely to need NVRAM polling in their latest BIOS versions.
 440
 441           NVRAM polling can detect at most the following keys: ThinkPad/Access
 442           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 443           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 551           ACPI-WMI is a proprietary extension to ACPI to expose parts of the

 553           defined methods and data blocks in a PNP0C14 device, which are then
 554           made available for userspace to call.
 555
 556           The implementation of this in Linux currently only exposes this to
 557           other kernel space drivers.

 559           This driver is a required dependency to build the firmware specific
 560           drivers needed on many machines, including Acer and HP laptops.

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