Intel Elkhart Lake exposes SCU/PMC as an ACPI device that only supports IPC functionality so add a platform driver supporting it. Interrupt is optional so we let intel_scu_ipc_probe() to decide based on the passed platform data whether it uses interrupt or polling.

This driver adds support for the ACPI-WMI (Windows Management
|
|
Instrumentation) mapper device (PNP0C14) found on some systems.
|
|
|
|
ACPI-WMI is a proprietary extension to ACPI to expose parts of the
|
|
ACPI firmware to userspace - this is done through various vendor
|
|
defined methods and data blocks in a PNP0C14 device, which are then
|
|
made available for userspace to call.
|
|
|
|
The implementation of this in Linux currently only exposes this to
|
|
other kernel space drivers.
|
|
|
|
This driver is a required dependency to build the firmware specific
|
|
drivers needed on many machines, including Acer and HP laptops.
|
|
|
|
It is safe to enable this driver even if your DSDT doesn't define
|
|
any ACPI-WMI devices.

Extra functionality will be available if the rfkill (CONFIG_RFKILL)

ALSA mixer will be made read-write). Please refer to the driver

Overriding LED state on ThinkPads can mask important

firmware alerts (like critical battery condition), or misled

the user into damaging the hardware (undocking or ejecting

the bay while buses are still active), etc.
|
|
|

LED control on the ThinkPad is write-only (with very few

exceptions on very ancient models), which makes it

impossible to know beforehand if important information will

be lost when one changes LED state.
|

the ones on the dock stations.

Some thinkpad models benefit from NVRAM polling to detect a few of

the hot key press events. If you know your ThinkPad model does not
|
|
need to do NVRAM polling to support any of the hot keys you use,
|
|
unselecting this option will save about 1kB of memory.
|
|
|
|
ThinkPads T40 and newer, R52 and newer, and X31 and newer are
|
|
unlikely to need NVRAM polling in their latest BIOS versions.
|
|
|
|
NVRAM polling can detect at most the following keys: ThinkPad/Access
|
|
IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
|
|
Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

IMRs are a set of registers that define read and write access masks

to prohibit certain system agents from accessing memory with 1 KiB

granularity.
|
|
|
|
IMRs make it possible to control read/write access to an address
|
|
by hardware agents inside the SoC. Read and write masks can be
|
|
defined for:
|
|
- eSRAM flush
|
|
- Dirty CPU snoop (write only)
|
|
- RMU access
|
|
- PCI Virtual Channel 0/Virtual Channel 1
|

Intel Smart Connect is a technology intended to permit devices to

update state by resuming for a short period of time at regular

will then remain awake until something triggers another suspend.
