> Let me clarify the reproduced steps,
> 1. Run a workload(Like as Openarena v0.8.8)
> 2. Navigate to /sys/class/drm/card0 to check P-state frequency
> 3. Observe some files indicated P-state frequency(gt_cur_freq_mhz is the
> current frequency, min/max are the min/max freqs, RP0 is the max P-state,
> RP1 is the "nominal" P-state, and RPn is the lowest frequency)
> 
> Actual: The value of RP0/RP1/RPn frequency returned from these files is
> equal to 0.
> Expected: It should be max/nominal/max freq.

The purpose is to check whether P-state frequency will increase or not while
running a workload.
