Thus,\nthe option parser was overwriting memory belonging to other variables, namely\nthe mmap_pages leading to a zero page sampling buffer. The bug was exposed only\nwhen compiling at -O0, probably because the compiler was padding variables at\nhigher optimization levels.\n\nThis patch fixes this problem by declaring user_interval as u64.

inheritance, led to believe it was off\nby default.\n\nThis patch fixes this logic by inverting the meaning of the -i option. By\ndefault inheritance is on whether you attach to a process (-p), a thread (-t)\nor start a process. If you pass -i, then you turn off inheritance. Turning off\ninheritance if you don\u0027t need it, helps limit perf resource usage as well.\n\nThe patch also fixes perf stat -t xxxx and perf record -t xxxx which did not\nstart the counters.\n\nAcked-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: David S.

browser, I realised that it would be\nbetter to introduce a new class, \"hists\" (short for \"histograms\"),\nrenaming the \"event_stat_id\" struct and the perf_session methods that\nwere really \"hists\" methods, as they manipulate only struct hists\nmembers, not touching anything in the other perf_session members.\n\nOther optimizations, such as calculating the maximum lenght of a symbol\nname present in an hists instance will be possible as we add them,\navoiding a re-traversal just for finding that information.\n\nThe rationale for the name \"hists\" to replace \"event_stat_id\" is that we\nmay have multiple sets of hists for the same event_stat id, as, for\ninstance, the \u0027perf diff\u0027 tool has, so event stat id is not what\ncharacterizes what this

lot of CPU buffers\nto read), in the next pass the CPU 0 buffer could contain a slice\nof several seconds of events. We\u0027ll read them all and notice we\u0027ve\nreached the period to flush. In the above example we flush the first\nhalf of the CPU 0 buffer, then we read the CPU 1 buffer where we\nhave events that were on the flush slice and then the reordering\nfails.\n\nIt\u0027s simple to reproduce with:\n\n\tperf lock record perf bench sched messaging\n\nTo solve this, we use a new solution that doesn\u0027t rely on an\nheuristical time slice period anymore but on a deterministic basis\nbased on how perf record does its job.\n\nperf record saves the buffers through passes. A pass is a tour\non every buffers from every CPUs. This is made in order: for\neach CPU we read the buffers of every counters. So the more\nbuffers we visit, the later will be the timstamps of their events.\n\nWhen perf record finishes a pass it records a\nPERF_RECORD_FINISHED_ROUND pseudo event.\nWe record the max timestamp t found in the pass n. Assuming these\ntimestamps are monotonic across cpus, we know that if a buffer\nstill has events with timestamps below t, they will be all available\nand then read in the pass n + 1.\nHence when we start to read the pass n + 2, we can safely flush every\nevents with timestamps below t.\n\n \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d PASS n \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n CPU 0 | CPU 1\n |\n cnt1 timestamps | cnt2 timestamps\n 1 | 2\n 2 | 3\n - | 4 \u003c--- max recorded\n\n \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d PASS n + 1 \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n CPU 0 | CPU 1\n |\n cnt1 timestamps | cnt2 timestamps\n 3 | 5\n 4 | 6\n 5 | 7 \u003c---- max recorded\n\n Flush every events below timestamp 4\n\n \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d PASS n + 2 \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n CPU 0 | CPU 1\n |\n cnt1 timestamps | cnt2 timestamps\n 6 | 8\n 7 | 9\n - | 10\n\n Flush every events below timestamp 7\n etc...\n\nIt also works on perf.data versions that don\u0027t have\nPERF_RECORD_FINISHED_ROUND pseudo events.
