[Intel-gfx] [PATCH v5 12/16] drm/i915/perf: Apply Wa_18013179988

2022-10-25 Thread Umesh Nerlige Ramappa
OA reports in the OA buffer contain an OA timestamp field that helps user calculate delta between 2 OA reports. The calculation relies on the CS timestamp frequency to convert the timestamp value to nanoseconds. The CS timestamp frequency is a function of the CTC_SHIFT value in RPM_CONFIG0. In DG2
