Ingo Molnar dc02bf7178 perf sched: Account for lost events, increase default buffering ... Output such lost event and state machine weirdness stats: TOTAL: | 14974.910 ms | 46384 | --------------------------------------------------- INFO: 8.865% lost events (19132 out of 215819, in 8 chunks) INFO: 0.198% state machine bugs (49 out of 24708) (due to lost events?) And increase buffering to -m 1024 (4 MB) by default. Since we use output multiplexing that kind of space is needed.
