402           (headphone and speakers), which is operated by the mute and (in
403           some ThinkPad models) volume hotkeys.
404 
405           If this option is enabled, ThinkPad-ACPI will export an ALSA card
406           with a single read-only mixer control, which should be used for
407           on-screen-display feedback purposes by the Desktop Environment.
408 
409           Optionally, the driver will also allow software control (the
410           ALSA mixer will be made read-write).  Please refer to the driver
411           documentation for details.
412 
413           All IBM models have both volume and mute control.  Newer Lenovo
414           models only have mute control (the volume hotkeys are just normal
415           keys and volume control is done through the main HDA mixer).

443           Overriding LED state on ThinkPads can mask important

446           the bay while buses are still active), etc.
447 
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.

454           and the driver will allow control of every LED, including

477

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

496           unlikely to need NVRAM polling in their latest BIOS versions.

625 
626           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
627           ACPI firmware to userspace - this is done through various vendor
628           defined methods and data blocks in a PNP0C14 device, which are then

844           This option provides a means to manipulate Isolated Memory Regions.
845           IMRs are a set of registers that define read and write access masks
846           to prohibit certain system agents from accessing memory with 1 KiB
847           granularity.
848 
849           IMRs make it possible to control read/write access to an address
850           by hardware agents inside the SoC. Read and write masks can be
851           defined for:
852                 - eSRAM flush
853                 - Dirty CPU snoop (write only)
854                 - RMU access

857                 - Non SMM mode
858 
859           Quark contains a set of eight IMR registers and makes use of those
860           registers during its bootup process.

884          feature without proper support may void your hardware warranty.
885 
886          If the proper BIOS support is found the driver will load and create
887          /sys/devices/system/ibm_rtl/.  The "state" variable will indicate
888          whether or not the BIOS is in PRTM.

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