Performance counter stats for 'grep -q -r duration_time. perf stat -e duration_time,ru_utime,ru_stime,cache-misses - grep -q -r duration_time. 'ru_stime', similarly to the already present 'duration_time' event.īoth events use the already collected rusage information obtained by wait4.Įxamples presenting cache-misses and rusage information in both human and To solve this I added two new tool internal events 'rusage_user_time'Īnd 'rusage_system_time' as well as their aliases 'ru_utime' and I found no way to retrieve this information using the available events When running perf stat the output for humans contains the timesīut using perf stats' machine-readable format does not provide this Times spend in user or kernel mode in a machine readable format. It bothered me that during benchmarking using perf stat (to collectįor example CPU cache events) I could not simultaneously retrieve the Next in thread: Arnaldo Carvalho de Melo: "Re: perf stat: add rusage utime and stime events".In reply to: Florian Fischer: " perf stat: add rusage utime and stime events".Previous message: Greg Kroah-Hartman: " PCI: xgene: Revert "PCI: xgene: Fix IB window setup"".Next message: Greg Kroah-Hartman: " clk: clps711x: Terminate clk_div_table with sentinel element".Linux-Kernel Archive: perf stat: add rusage utime and stime events perf stat: add rusage utime and stime events From: Florian Fischer
