+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
