was fishy on the thread\nsynthesizing routines, at least for the case where the workload is started\nfrom \u0027perf record\u0027, as -1 is the default for target_tid in \u0027perf record --tid\u0027\nparameter, so somehow we were trying to synthesize the PERF_RECORD_MMAP and\nPERF_RECORD_COMM events for the thread -1, a bug.\n\nSo I investigated this and noticed that when we introduced support for\nrecording a process and its threads using --pid some bugs were introduced and\nthat the way to fix it was to instead of passing the target_tid to the event\nsynthesizing routines we should better pass the thread_map that has the list of\nthreads for a --pid or just the single thread for a --tid.\n\nChecked in the following ways:\n\nOn a 8-way machine run

no sample_id_all\n\nIf we are running the new perf on an old kernel without support for\nsample_id_all, we should fall back to the old unordered processing of\nevents. If we didn\u0027t than we would *always* process events without\ntimestamps out of order, whether or not we hit a reordering race. 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": "68a7a771ad0e2959983729bf88cbc74a7014438f", "tree": "6d63982c1bd04aa461b4fdb59996cf6faad6fba4", "parents": [ "c3a34e06db25a8c74e196517732d65cdb56028ec" ], "author": { "name": "Franck Bui-Huu", "email": "fbuihuu@gmail.com", "time": "Fri Dec 10 22:06:26 2010 +0100" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Thu Dec 16 09:41:45 2010 -0200" }, "message": "perf buildid-cache: Fix symbolic link handling\n\nThis was broken since link(2) doesn\u0027t dereference symbolic\nlinks.
