+What: /sys/bus/wmi/devices/.../driver_override
+Date: February 2024
+Contact: Armin Wolf <W_Armin@gmx.de>
+Description:
+ This file allows the driver for a device to be specified which
+ will override standard ID table matching.
+ When specified, only a driver with a name matching the value
+ written to driver_override will have an opportunity to bind
+ to the device.
+ The override is specified by writing a string to the
+ driver_override file (echo wmi-event-dummy > driver_override).
+ The override may be cleared with an empty string (echo > \
+ driver_override) which returns the device to standard matching
+ rules binding.
+ Writing to driver_override does not automatically unbind the
+ device from its current driver or make any attempt to automatically
+ load the specified driver. If no driver with a matching name is
+ currently loaded in the kernel, the device will not bind to any
+ driver.
+ This also allows devices to opt-out of driver binding using a
+ driver_override name such as "none". Only a single driver may be
+ specified in the override, there is no support for parsing delimiters.

-Set udev rules for PMF Smart PC Builder
----------------------------------------
-
-AMD PMF(Platform Management Framework) Smart PC Solution builder has to set the system states
-like S0i3, Screen lock, hibernate etc, based on the output actions provided by the PMF
-TA (Trusted Application).
-
-In order for this to work the PMF driver generates a uevent for userspace to react to. Below are
-sample udev rules that can facilitate this experience when a machine has PMF Smart PC solution builder
-enabled.
-
-Please add the following line(s) to
-``/etc/udev/rules.d/99-local.rules``::
-
- DRIVERS=="amd-pmf", ACTION=="change", ENV{EVENT_ID}=="0", RUN+="/usr/bin/systemctl suspend"
- DRIVERS=="amd-pmf", ACTION=="change", ENV{EVENT_ID}=="1", RUN+="/usr/bin/systemctl hibernate"
- DRIVERS=="amd-pmf", ACTION=="change", ENV{EVENT_ID}=="2", RUN+="/bin/loginctl lock-sessions"
-
-EVENT_ID values:
-0= Put the system to S0i3/S2Idle
-1= Put the system to hibernate
-2= Lock the screen
