 365
 366           If this option is enabled, ThinkPad-ACPI will export an ALSA card

 372           documentation for details.
 373
 374           All IBM models have both volume and mute control.  Newer Lenovo

 408
 409           LED control on the ThinkPad is write-only (with very few
 410           exceptions on very ancient models), which makes it
 411           impossible to know beforehand if important information will
 412           be lost when one changes LED state.
 413
 414           Users that know what they are doing can enable this option
 415           and the driver will allow control of every LED, including
 416           the ones on the dock stations.
 417
 418           Never enable this option on a distribution kernel.
 419

 421           use, and need to control the important firmware LEDs.

 431           This feature often won't work well, depending on ThinkPad model,
 432           display state, video output devices in use, whether there is a X
 433           server running, phase of the moon, and the current mood of
 434           Schroedinger's cat.  If you can use X.org's RandR to control
 435           your ThinkPad's video output ports instead of this feature,
 436           don't think twice: do it and say N here to save memory and avoid
 437           bad interactions with X.org.
 438
 439           NOTE: access to this feature is limited to processes with the
 440           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 441           where it interacts badly with X.org.

 451           Some thinkpad models benefit from NVRAM polling to detect a few of
 452           the hot key press events.  If you know your ThinkPad model does not
 453           need to do NVRAM polling to support any of the hot keys you use,
 454           unselecting this option will save about 1kB of memory.
 455
 456           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 457           unlikely to need NVRAM polling in their latest BIOS versions.
 458
 459           NVRAM polling can detect at most the following keys: ThinkPad/Access
 460           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 461           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 568
 569           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 570           ACPI firmware to userspace - this is done through various vendor
 571           defined methods and data blocks in a PNP0C14 device, which are then
 572           made available for userspace to call.
 573
 574           The implementation of this in Linux currently only exposes this to
 575           other kernel space drivers.
 576
 577           This driver is a required dependency to build the firmware specific
 578           drivers needed on many machines, including Acer and HP laptops.

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

 810         ---help---
 811           This driver provides support for modifying paramaters on systems
 812           equipped with Intel's Rapid Start Technology. When put in an ACPI
 813           sleep state, these devices will wake after either a configured
 814           timeout or when the system battery reaches a critical state,
 815           automatically copying memory contents to disk. On resume, the
 816           firmware will copy the memory contents back to RAM and resume the OS
 817           as usual.

 822         ---help---
 823           Intel Smart Connect is a technology intended to permit devices to
 824           update state by resuming for a short period of time at regular
 825           intervals. If a user enables this functionality under Windows and
 826           then reboots into Linux, the system may remain configured to resume
 827           on suspend. In the absence of any userspace to support it, the system
 828           will then remain awake until something triggers another suspend.
 829
 830           This driver checks to determine whether the device has Intel Smart
 831           Connect enabled, and if so disables it.

 837           This driver provides support for the pvpanic device.  pvpanic is
 838           a paravirtualized device provided by QEMU; it lets a virtual machine
 839           (guest) communicate panic events to the host.
