 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

 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.

 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).

 550           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 551           ACPI firmware to userspace - this is done through various vendor
 552           defined methods and data blocks in a PNP0C14 device, which are then
 553           made available for userspace to call.
 554
 555           The implementation of this in Linux currently only exposes this to
 556           other kernel space drivers.

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