 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

 445           the user into damaging the hardware (undocking or ejecting
 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.
 452
 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.

 475           don't think twice: do it and say N here to save memory and avoid
 476           bad interactions with X.org.
 477
 478           NOTE: access to this feature is limited to processes with the
 479           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 480           where it interacts badly with X.org.

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

 494
 495           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 496           unlikely to need NVRAM polling in their latest BIOS versions.
 497
 498           NVRAM polling can detect at most the following keys: ThinkPad/Access

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

 828           This option provides a means to manipulate Isolated Memory Regions.
 829           IMRs are a set of registers that define read and write access masks
 830           to prohibit certain system agents from accessing memory with 1 KiB
 831           granularity.
 832
 833           IMRs make it possible to control read/write access to an address
 834           by hardware agents inside the SoC. Read and write masks can be
 835           defined for:
 836                 - eSRAM flush
 837                 - Dirty CPU snoop (write only)
 838                 - RMU access
 839                 - PCI Virtual Channel 0/Virtual Channel 1
 840                 - SMM mode
 841                 - Non SMM mode
 842
 843           Quark contains a set of eight IMR registers and makes use of those
 844           registers during its bootup process.

 958           then reboots into Linux, the system may remain configured to resume
 959           on suspend. In the absence of any userspace to support it, the system
