[Intel-gfx] [CI 1/3] drm/i915/selftests: Verify frequency scaling with RPS

2020-04-18 Thread Chris Wilson
One of the core tenents of reclocking the GPU is that its throughput scales with the clock frequency. We can observe this by incrementing a loop counter on the GPU, and compare the different execution rates at the notional RPS frequencies. Signed-off-by: Chris Wilson --- drivers/gpu/drm/i915/gt/
