Thanks for information. Could you please enable the trace event of
amd_pstate_perf before you run the test.

echo 1 > /sys/kernel/tracing/events/amd_cpu/enable

Then dump the traces with "cat /sys/kernel/debug/tracing/trace". We can
double confirm whether the amd-pstate driver program the correct
performance value in your processor.

Thanks,
Ray
