Re: [Mesa-dev] Perfetto CPU/GPU tracing

I can vouch for the usefulness of the combined trace timeline showing CPU core usage, filtered application events and GPU usage. Android systrace shows this data -- I've used it from both an app developer perspective to fix countless performance bugs and from a whole-system perspective to tune

[Mesa-dev] Perfetto CPU/GPU tracing

I recently opened issue 4262 to begin the discussion on integrating perfetto into mesa. *Background* System-wide tracing is an invaluable tool for developers to find and fix performance problems. The perfetto project enables a combined
