yes: [jolsa@krava perf]$ ./perf record kill kill: not enough arguments [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.016 MB perf.data (7 samples) ] [jolsa@krava perf]$ ./perf report --header-only -I [jolsa@krava perf]$ but I'm actualy using branch I found in your tree: ccdavid/toup_june12_pipeheaders_00, maybe it's not the latest [jolsa@krava perf]$ git log --oneline | head -1 a16f0acca1d2 perf header: add event desc to pipe-mode header jirka
