401           All IBM models have both volume and mute control.  Newer Lenovo
402           models only have mute control (the volume hotkeys are just normal
403           keys and volume control is done through the main HDA mixer).

431           Overriding LED state on ThinkPads can mask important
432           firmware alerts (like critical battery condition), or misled
433           the user into damaging the hardware (undocking or ejecting
434           the bay while buses are still active), etc.
435 
436           LED control on the ThinkPad is write-only (with very few
437           exceptions on very ancient models), which makes it
438           impossible to know beforehand if important information will
439           be lost when one changes LED state.
440 
441           Users that know what they are doing can enable this option
442           and the driver will allow control of every LED, including
443           the ones on the dock stations.
444 
445           Never enable this option on a distribution kernel.

457 
458           This feature often won't work well, depending on ThinkPad model,
459           display state, video output devices in use, whether there is a X
460           server running, phase of the moon, and the current mood of
461           Schroedinger's cat.  If you can use X.org's RandR to control
462           your ThinkPad's video output ports instead of this feature,
463           don't think twice: do it and say N here to save memory and avoid
464           bad interactions with X.org.
465 
466           NOTE: access to this feature is limited to processes with the
467           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
468           where it interacts badly with X.org.

478           Some thinkpad models benefit from NVRAM polling to detect a few of
479           the hot key press events.  If you know your ThinkPad model does not
480           need to do NVRAM polling to support any of the hot keys you use,
481           unselecting this option will save about 1kB of memory.
482 
483           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
484           unlikely to need NVRAM polling in their latest BIOS versions.
485 
486           NVRAM polling can detect at most the following keys: ThinkPad/Access
487           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
488           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

610 
611           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
612           ACPI firmware to userspace - this is done through various vendor
613           defined methods and data blocks in a PNP0C14 device, which are then
614           made available for userspace to call.
615

617           other kernel space drivers.

805           Intel Calpella platforms support dynamic power sharing between the
806           CPU and GPU, maximizing performance in a given TDP.  This driver,
807           along with the CPU frequency and i915 drivers, provides that

816           This option provides a means to manipulate Isolated Memory Regions.
817           IMRs are a set of registers that define read and write access masks
818           to prohibit certain system agents from accessing memory with 1 KiB
819           granularity.
820 
821           IMRs make it possible to control read/write access to an address
822           by hardware agents inside the SoC. Read and write masks can be
823           defined for:
824                 - eSRAM flush
825                 - Dirty CPU snoop (write only)
826                 - RMU access
827                 - PCI Virtual Channel 0/Virtual Channel 1
828                 - SMM mode

830 
831           Quark contains a set of eight IMR registers and makes use of those
832           registers during its bootup process.

847          /sys/devices/system/ibm_rtl/.  The "state" variable will indicate
848          whether or not the BIOS is in PRTM.

946           then reboots into Linux, the system may remain configured to resume
947           on suspend. In the absence of any userspace to support it, the system
948           will then remain awake until something triggers another suspend.
