--- Comment #28 from Sagar Kamble <sagar.a.kamble at intel.com> ---
SLPC Turbo helps resolve these regressions. This was tested with v9 GuC
firmware and patches at https://patchwork.freedesktop.org/series/17537/.
Perf-meter output shows fluctuations in the frequency with Host RPS wheres SLPC
Turbo keeps running at high frequency. CPG is disabled for GT3 SKU so CPG
forcewakes latency may not be stalling submission rate as in APL. More
debug/analysis in progress.
