Returning mailing list back. Just tried ./intel-gpu-overlay. From what I see it wonderfully works even when I wiped out event->sampling_period from i915 RFC PMU and prohibited it. Mind that I did not remove sampling inside i915 RFC PMU: I removed only timer staff which is exposed to the perf core. Sampling itself is still there and works as far as I see. Thus, the question: why event->hw->hrtimer staff was introduced in i915 RFC PMU? Right now it does not make sense to me.

So, I try to remind. It's integral to all the sampling counters we use; which are the majority of the events exposed and used by intel-gpu-overlay. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
