then made several perf_session methods\nreceive a point to it instead of a pointer to perf_session, and kept the\nevent_stats and hists rb_tree in perf_session.\n\nWhile working on the new newt based 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

events.\n\nIndeed the time period based flushing is not suitable anymore\nin the following case, assuming we have a flush period of two\nseconds.\n\n CPU 0 | CPU 1\n |\n cnt1 timestamps | cnt1 timestamps\n |\n 0 | 0\n 1 | 1\n 2 | 2\n 3 | 3\n [...] | [...]\n 4 seconds later\n\nIf we spend too much time to read the buffers (case of a lot of\nevents to record in each buffers or when we have a 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.
