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

386           Overriding LED state on ThinkPads can mask important

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.

415           server running, phase of the moon, and the current mood of

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

802         depends on ACPI
803         ---help---
804           Intel Smart Connect is a technology intended to permit devices to
805           update state by resuming for a short period of time at regular
806           intervals. If a user enables this functionality under Windows and
807           then reboots into Linux, the system may remain configured to resume
808           on suspend. In the absence of any userspace to support it, the system
809           will then remain awake until something triggers another suspend.
810 
811           This driver checks to determine whether the device has Intel Smart
812           Connect enabled, and if so disables it.

817         ---help---
818           This driver provides support for the pvpanic device.  pvpanic is
819           a paravirtualized device provided by QEMU; it lets a virtual machine
820           (guest) communicate panic events to the host.

826           Needed on Baytrail platforms for access to the IOSF Sideband Mailbox
827           Interface. This is a requirement for systems that need to configure
828           the PUNIT for power management features such as RAPL.
