I was looking for a simple mechanism to measure GPU workloads, it turns out that the support is already present in the msm driver. 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.
