In\nother words, instead of there being a chance of not attributing samples\ncorrectly, we would guarantee that samples would not be attributed.\n\nWhile processing all events without timestamps before events with\ntimestamps may seem like an intuitive solution, it falls down as\nPERF_RECORD_EXIT events would also be processed before any samples.\nEven with a workaround for that case, samples before/after an exec would\nnot be attributed correctly.\n\nThis patch allows commands to indicate whether they need to fall back to\nunordered processing, so that commands that do not care about timestamps\non every event will not be affected. If we do fallback, this will print\nout a warning if report -D was invoked.\n\nThis patch adds the test in perf_session__new so that we only need to\ntest once per session. Commands that do not use an event_ops (such as\nrecord and top) can simply pass NULL in it\u0027s place.\n\nAcked-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nLKML-Reference: \u003c1291951882-sup-6069@au1.ibm.com\u003e\nSigned-off-by: Ian Munsie \u003cimunsie@au1.ibm.com\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "ce47dc56a2241dc035160a85bc5e34283cdd622c", "tree": "d9404df9d3ca0ddacdd8faae791ece27206dece4", "parents": [ "965bb6beaf70862d3846e330ea7a14996d82c499" ], "author": { "name": "Chris Samuel", "email": "chris@csamuel.org", "time": "Sat Nov 13 13:35:06 2010 +1100" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Mon Dec 06 12:52:35 2010 -0200" }, "message": "perf tools: Catch a few uncheck calloc/malloc\u0027s\n\nThere were a few stray calloc()\u0027s and malloc()\u0027s which were not having\ntheir return values checked for success.\n\nAs the calling code either already coped with failure or didn\u0027t actually\ncare we just return -ENOMEM at that point.\n\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Chris Samuel \u003cchris@csamuel.org\u003e\nLKML-Reference: \u003c4CDDF95A.1050400@csamuel.org\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "640c03ce837fe8d4b56342aba376ea0da3960459", "tree": "e954290ccacf032ab4d9052eac01710fda1b7fab", "parents": [ "c980d1091810df13f21aabbce545fd98f545bbf7" ], "author": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Thu Dec 02 14:10:21 2010 -0200" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Sat Dec 04 23:05:19 2010 -0200" }, "message": "perf session: Parse sample earlier\n\nAt perf_session__process_event, so that we reduce the number of lines in eache\ntool sample processing routine that now receives a sample_data pointer already\nparsed.\n\nThis will also be useful in the next patch, where we\u0027ll allow sample the\nidentity fields in MMAP, FORK, EXIT, etc, when it will be possible to see (cpu,\ntimestamp) just after before every event.\n\nAlso validate callchains in perf_session__process_event, i.e. as early as\npossible, and keep a counter of the number of events discarded due to invalid\ncallchains, warning the user about it if it happens.\n\nThere is an assumption that was kept that all events have the same sample_type,\nthat will be dealt with in the future, when this preexisting limitation will be\nremoved.\n\nTested-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nReviewed-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nAcked-by: Ian Munsie \u003cimunsie@au1.ibm.com\u003e\nAcked-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Frédéric Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ian Munsie \u003cimunsie@au1.ibm.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Stephane Eranian \u003ceranian@google.com\u003e\nLKML-Reference: \u003c1291318772-30880-4-git-send-email-acme@infradead.org\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "454c407ec17a0c63e4023ac0877d687945a7df4a", "tree": "1271299a59a89419c0dd4dcbf29b4492b63555ca", "parents": [ "789688faef5b3ba78065beaf2f3d6f1c839f74a3" ], "author": { "name": "Tom Zanussi", "email": "tzanussi@gmail.com", "time": "Sat May 01 01:41:20 2010 -0500" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Sun May 02 13:36:56 2010 -0300" }, "message": "perf: add perf-inject builtin\n\nCurrently, perf \u0027live mode\u0027 writes build-ids at the end of the\nsession, which isn\u0027t actually useful for processing live mode events.\n\nWhat would be better would be to have the build-ids sent before any of\nthe samples that reference them, which can be done by processing the\nevent stream and retrieving the build-ids on the first hit.
