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
