--- Comment #20 from Perry Yuan(AMD) (Perry.Yuan@amd.com) ---
Hi bro,
I checked your cpuinfo log, the CPPC is not enabled on your system, so the MSR
will not work at all, EPP values need to update through MSR interface and you
also see the crash log when you try to read or write MSR.
for example, this is captured from my system, lscpu need to expose the cppc
flag on your system like mine.
------------------------------------------------------
CPU family: 25
Model: 116
# lscpu | grep cppc
rdpru wbnoinvd <CPPC> arat npt lbrv...
------------------------------------------------------
If your system BIOS have no such option, it will not allow amd pstate driver
work as expected.
Please contact with ASUS to request new BIOS to enable CPPC for your system.
Perry.
