Android perf tests: add ATrace counters for trace loops TraceLoopFrameTimeAvgUs: frame time averaged over last loop, in us. Traced after each full loop is finished. TraceStage: tracking trace stage 0 (implicit) - before app and warmup starts 1 - initial warmup 2 - extended warmup for short traces 3 - running a trial 0 - trial finished (exit if single trial, or back to 3 if another trial) Intended for use with perfetto tracing, needs this in ftrace_config: atrace_apps: "com.android.angle.test:test_process" Useful for looking for correlations with other events, such as gpu frequency changes.
