But during\nthis merge, we forgot to merge callchains.\n\nSo imagine we have three threads (tids: 1000, 1001, 1002) that\nbelong to comm \"foo\".\n\ntid 1000 got 100 events\ntid 1001 got 10 events\ntid 1002 got 3 events\n\nOnce we merge these histograms to get a per comm result, we\u0027ll\nfinally get:\n\n\"foo\" got 113 events\n\nThe problem is if we merge 1000 and 1001 histograms into 1002, then\nthe end merge result, wrt callchains, will be only callchains that\nbelong to 1002.\nThis is because we haven\u0027t handled callchains in the merge. Only those\nfrom one of the threads inside a common comm survive.\n\nIt means during this merge, we can lose a lot of callchains.\n\nFix this by implementing callchains merge and apply it on histograms\nthat collapse.\n\nReported-by: Christoph Hellwig \u003chch@infradead.org\u003e\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "6cb8e56161c4103af9178ea45ba61ddbde02969a", "tree": "bfb161555cc6aa4d50a1dbfbaaba2e84808959d4", "parents": [ "d2009c5130b627d3efccae8ed36cd43450c8486d" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Sun Aug 22 20:18:01 2010 +0200" }, "committer": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Sun Aug 22 20:43:51 2010 +0200" }, "message": "perf: Rename append_callchain into callchain_append\n\nDo that to start a consistant callchain API namespace.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\n" }, { "commit": "d2009c5130b627d3efccae8ed36cd43450c8486d", "tree": "22afece12b12600d9132ab76f8fe74425548351d", "parents": [ "f4e7ac0a233a4dc9b51345546ab69c64bb43e2c1" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Sun Aug 22 20:05:22 2010 +0200" }, "committer": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Sun Aug 22 20:43:17 2010 +0200" }, "message": "perf: Keep track of the max depth of a callchain\n\nIn order to implement callchains collapsing, we need to keep\ntrack of the maximum depth in a histogram tree of callchains.\nThis way we\u0027ll avoid allocating an arbitrary temporary buffer\nsize on callchain merge time.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\n" }, { "commit": "f4e7ac0a233a4dc9b51345546ab69c64bb43e2c1", "tree": "26de697385ad30163970160e4c0c8ed9a4dd491b", "parents": [ "8b9e74eb8af808807192d16b76565c27154ae7ed" ], "author": { "name": "Kirill A.

Because we pass the number of events\nmuliplied by their period as the total number of hits to the\ncallchain filtering, while callchains expect this number to be\nthe number of raw hits.\n\nperf report -g graph was simply not working, showing no graph unless\nthe min percent was zero. And even there the percentage of the\nbranches was always 0. And may be fractal filtering was broken on\nthe first branch level too.\n\nflat also was broken, but it was hidden because of other breakages.\n\nAnyway fix this by counting using periods on callchains.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "97aa1052739c6a06cb6b0467dbf410613d20bc97", "tree": "1bcf54fbe3fe39b6941f898a6927b6ac14df9996", "parents": [ "869599ceda4a035cdb3345c563b74cdeef10f790" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Thu Jul 08 06:06:17 2010 +0200" }, "committer": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Thu Jul 08 06:20:15 2010 +0200" }, "message": "perf: Resurrect flat callchains\n\nInitialize the callchain radix tree root correctly.\n\nWhen we walk through the parents, we must stop after the root, but\nsince it wasn\u0027t well initialized, its parent pointer was random.\n\nAlso the number of hits was random because uninitialized, hence it\nwas part of the callchain while the root doesn\u0027t contain anything.\n\nThis fixes segfaults and percentages followed by empty callchains\nwhile running:\n\n\tperf report -g flat\n\nReported-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: 2.6.31.x-2.6.34.x \u003cstable@kernel.org\u003e\n" }, { "commit": "8bd0e1be25c43a9fbd33a8de06449088879d527a", "tree": "8f24493dfd45df467faa69e2ecef67b8321932ef", "parents": [ "39ef13a4ac28aa64cfe1bc36e6e00f1096707a28", "b7dcb857cc3eb89136111fefe89780129c1af1d7" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Jul 06 09:00:32 2010 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Jul 06 09:00:32 2010 +0200" }, "message": "Merge branch \u0027perf/core\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux-2.6 into perf/core\n" }, { "commit": "b7dcb857cc3eb89136111fefe89780129c1af1d7", "tree": "21350796c508db4fb782f3e61eb63f62c3527f69", "parents": [ "b2a3c12b7442247c440f7083d48ef05716753ec1" ], "author": { "name": "Masami Hiramatsu", "email": "mhiramat@redhat.com", "time": "Wed May 19 15:57:49 2010 -0400" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Mon Jul 05 18:51:33 2010 -0300" }, "message": "perf probe: Support static and global variables\n\nAdd static and global variables support to perf probe.\nThis allows user to trace non-local variables (and\nstructure members) at probe points.\n\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nLKML-Reference: \u003c20100519195749.2885.17451.stgit@localhost6.localdomain6\u003e\nSigned-off-by: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "b2a3c12b7442247c440f7083d48ef05716753ec1", "tree": "c3a3d0bb442e285979b0dbeecfbf0c04a8b3743e", "parents": [ "73317b954041031249e8968d2e9023ff4e960d99" ], "author": { "name": "Masami Hiramatsu", "email": "mhiramat@redhat.com", "time": "Wed May 19 15:57:42 2010 -0400" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Mon Jul 05 18:50:27 2010 -0300" }, "message": "perf probe: Support tracing an entry of array\n\nAdd array-entry tracing support to perf probe.
