With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant.

Then in (2),\nxfce4-panel sleeps, it is first waken up in (3) and eventually\nscheduled in (5).\n\nThe latency reported is then 1504 - 1495 \u003d 9 secs, as reported by perf\nsched. But this is wrong, we are confident in the fact the traces are\nnicely serialized while we should actually more trust the timestamps.\n\nIf we reorder by timestamps we get:\n\n(1) Xorg-4276 [001] 1494.663860125: sched_wakeup: task xfce4-panel:4569 [120] success\u003d1 [000]\n(2) [init]-0 [000] 1494.663899990: sched_switch: task swapper:0 [140] (R) \u003d\u003d\u003e xfce4-panel:4569 [120]\n(3) xfce4-panel-4569 [000] 1494.663928373: sched_switch: task xfce4-panel:4569 [120] (S) \u003d\u003d\u003e swapper:0 [140]\n(4) Xorg-4276 [001] 1504.098252756: sched_wakeup: task xfce4-panel:4569 [120] success\u003d1 [000]\n(5) perf-5219 [000] 1504.100353302: sched_switch: task perf:5219 [120] (S) \u003d\u003d\u003e xfce4-panel:4569 [120]\n\nNow the trace make more sense, xfce4-panel is sleeping. Then it is\nwoken up in (1), scheduled in (2)\nIt goes to sleep in (3), woken up in (4) and scheduled in (5).\n\nNow, latency captured between (1) and (2) is of 39 us.\nAnd between (4) and (5) it is 2.1 ms.\n\nSuch pattern of bad serializing is the origin of the high latencies\nreported by perf sched.\n\nBasically, we need to check whether wake up time is higher than\nschedule out time.
