Not exactly what you want but might be close: git clone https://github.com/dsahern/linux git checkout perf-full-monty make -C tools/perf perf sched record -ag -- sleep 1 perf sched timehist -S shows the grains of sand (each sample) and then a runtime summary byt task. Example report attached for box just running a few VMs. David --------------090009060909070805060702 Content-Type: text/plain; charset=UTF-8; x-mac-type="0"; x-mac-creator="0"; name="timehist-ex"
