  25
  26	  ACPI-WMI is a proprietary extension to ACPI to expose parts of the
  27	  ACPI firmware to userspace - this is done through various vendor
  28	  defined methods and data blocks in a PNP0C14 device, which are then
  29	  made available for userspace to call.
  30
  31	  The implementation of this in Linux currently only exposes this to
  32	  other kernel space drivers.
  33
  34	  This driver is a required dependency to build the firmware specific
  35	  drivers needed on many machines, including Acer and HP laptops.

 524	  This is a driver for the IBM and Lenovo ThinkPad laptops. It adds

 528	  <file:Documentation/admin-guide/laptops/thinkpad-acpi.rst> and
 529	  <http://ibm-acpi.sf.net/> .
 530
 531	  This driver was formerly known as ibm-acpi.
 532
 533	  Extra functionality will be available if the rfkill (CONFIG_RFKILL)
 534	  and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
 535	  Note that if you want ThinkPad-ACPI to be built-in instead of
 536	  modular, ALSA and rfkill will also have to be built-in.

 552	  with a single read-only mixer control, which should be used for

 554
 555	  Optionally, the driver will also allow software control (the

1072	  This option provides a means to manipulate Isolated Memory Regions.
1073	  IMRs are a set of registers that define read and write access masks

1077	  IMRs make it possible to control read/write access to an address
1078	  by hardware agents inside the SoC. Read and write masks can be
