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 struct and the functions that manipulate it do.\n\nCc: Eric B Munson \u003cebmunson@us.ibm.com\u003e\nCc: Frédéric Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Mike Galbraith

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.

Doing\nthat in perf-record itself, however, is off-limits.\n\nThis patch introduces perf-inject, which does the same job while\nleaving perf-record untouched. Normal mode perf still records the\nbuild-ids at the end of the session as it should, but for live mode,\nperf-inject can be injected in between the record and report steps\ne.g.:\n\nperf record -o - ./hackbench 10 | perf inject -v -b | perf report -v -i -\n\nperf-inject reads a perf-record event stream and repipes it to stdout.\nAt any point the processing code can inject other events into the\nevent stream - in this case build-ids (-b option) are read and\ninjected as needed into the event stream.\n\nBuild-ids are just the first user of perf-inject - potentially\nanything that needs userspace processing to augment the trace stream\nwith additional information could make use of this facility.\n\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Frédéric Weisbecker \u003cfweisbec@gmail.com\u003e\nLKML-Reference: \u003c1272696080-16435-3-git-send-email-tzanussi@gmail.com\u003e\nSigned-off-by: Tom Zanussi \u003ctzanussi@gmail.com\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "789688faef5b3ba78065beaf2f3d6f1c839f74a3", "tree": "4d4bf78c420cbb0a135a10c602f49566dce1dcd4", "parents": [ "fb72014d98afd51e85aab9c061344ef32d615606" ], "author": { "name": "Tom Zanussi", "email": "tzanussi@gmail.com", "time": "Sat May 01 01:41:19 2010 -0500" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Sun May 02 12:04:05 2010 -0300" }, "message": "perf/live: don\u0027t synthesize build ids at the end of a live mode trace\n\nIt doesn\u0027t really make sense to record the build ids at the end of a\nlive mode session - live mode samples need that information during the\ntrace rather than at the end.\n\nLeave event__synthesize_build_id() in place, however; we\u0027ll still be\nusing that to synthesize build ids in a more timely fashion in a\nfuture patch.\n\nCc: Frédéric Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nLKML-Reference: \u003c1272696080-16435-2-git-send-email-tzanussi@gmail.com\u003e\nSigned-off-by: Tom Zanussi \u003ctzanussi@gmail.com\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "fb72014d98afd51e85aab9c061344ef32d615606", "tree": "18713d4d1084870c604b512396b893944a2bbdab", "parents": [ "bc4b473f1aa2ef785ccfd890a24a1de5a6660f98" ], "author": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Fri Apr 30 19:31:12 2010 -0300" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Sun May 02 12:00:44 2010 -0300" }, "message": "perf tools: Don\u0027t use code surrounded by __KERNEL__\n\nWe need to refactor code to be explicitely shared by the kernel and at\nleast the tools/ userspace programs, so, till we do that, copy the bare\nminimum bitmap/bitops code needed by tools/perf.\n\nReported-by: \"H.
