- Logistically it might be more practical to contain this to the graphics stack. It seems fair to consider that if we can't see a very compelling benefit to building on perf, then containing this work to drivers/gpu/drm/i915 may simplify the review process as well as future maintenance and development.
I think even we all initially like to go with perf but it appears later that we might need to stick this more close with i915 driver. Also think about to enable global profiling for all graphics clients, extending or enabling it within i915 specific interface seems more feasible instead of trying to create another PMU driver like previous implementation attempt to suit the need for different gfx perf data definition. Robert, thanks for send and elaborate on this. -- Open Source Technology Center, Intel ltd. $gpg --keyserver wwwkeys.pgp.net --recv-keys 4D781827
