[PATCH 2/9] intel_gpu_top: aim for 2000 samples per frame

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The previous sample rate of ~167 per frame was rather low in relation to
frequency of the events being measured and so for example the derived
busy status could become quite unstable at times.
