443           Overriding LED state on ThinkPads can mask important
444           firmware alerts (like critical battery condition), or misled
445           the user into damaging the hardware (undocking or ejecting
446           the bay while buses are still active), etc.
448           LED control on the ThinkPad is write-only (with very few
449           exceptions on very ancient models), which makes it
450           impossible to know beforehand if important information will
451           be lost when one changes LED state.
453           Users that know what they are doing can enable this option
454           and the driver will allow control of every LED, including
455           the ones on the dock stations.

492           need to do NVRAM polling to support any of the hot keys you use,

495           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
496           unlikely to need NVRAM polling in their latest BIOS versions.
498           NVRAM polling can detect at most the following keys: ThinkPad/Access
499           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
500           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

867           The Intel Platform Controller Hub for Intel Core SoCs provides access
868           to Power Management Controller registers via a PCI interface. This
869           driver can utilize debugging capabilities and supported features as
870           exposed by the Power Management Controller.
872           Supported features:
873                 - SLP_S0_RESIDENCY counter.

879          Enable support for IBM Premium Real Time Mode (PRTM).
880          This module will allow you the enter and exit PRTM in the BIOS via
881          sysfs on platforms that support this feature.  System in PRTM will
882          not receive CPU-generated SMIs for recoverable errors.  Use of this
883          feature without proper support may void your hardware warranty.
885          If the proper BIOS support is found the driver will load and create
886          /sys/devices/system/ibm_rtl/.  The "state" variable will indicate
887          whether or not the BIOS is in PRTM.
888          state = 0 (BIOS SMIs on)
889          state = 1 (BIOS SMIs off)

969           This driver provides support for modifying paramaters on systems
970           equipped with Intel's Rapid Start Technology. When put in an ACPI
971           sleep state, these devices will wake after either a configured
972           timeout or when the system battery reaches a critical state,
973           automatically copying memory contents to disk. On resume, the
974           firmware will copy the memory contents back to RAM and resume the OS
975           as usual.

981           Intel Smart Connect is a technology intended to permit devices to
982           update state by resuming for a short period of time at regular
983           intervals. If a user enables this functionality under Windows and
984           then reboots into Linux, the system may remain configured to resume
985           on suspend. In the absence of any userspace to support it, the system
986           will then remain awake until something triggers another suspend.
988           This driver checks to determine whether the device has Intel Smart
989           Connect enabled, and if so disables it.
