In this series I try to make use of the hardware counters where possible for a more accurate workload estimation. Please review and share your thoughts on this. I could have piggybacked on the devfreq samples and accumulated the busytimes, but I chose not to, since it puts a dependency on the gpu devfreq which in itself is an optional feature. There is one pending issue with GPU recovery + sampling use case, which I plan to address soon.
