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": "bbde588bfacb990542eed043d89c8591d4ae9211", "tree": "62ce715c9604177231f1d5e77e1a62d438061859", "parents": [ "68a7a771ad0e2959983729bf88cbc74a7014438f" ], "author": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Thu Dec 16 09:43:47 2010 -0200" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Thu Dec 16 09:43:47 2010 -0200" }, "message": "perf buildid-list: Fix error return for success\n\nIt was always returning -1 (255), confusing test scripts.\n\nReported-by: Han Pingtian \u003cphan@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Han Pingtian \u003cphan@redhat.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Stephane Eranian \u003ceranian@google.com\u003e\nCc: Tom Zanussi \u003ctzanussi@gmail.com\u003e\nLKML-Reference: \u003cnew-submission\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.

LIB_OBJS\n\nWhen we build perf we place all of the .o files from the library files\n(util, arch/x/util, etc) into libperf.a which is then linked into perf.\n\nThe problem is that the linker will by default only consider .o files\nwithin the .a archive if they are necessary to satisfy an unresolved\nsymbol. As weak functions are not unresolved, it will not consider a .o\nfile from the archive containing the strong versions of weak functions\nunless it requires it for another reason.\n\nThis patch adds the --whole-archive flags to the linker when passing in\nthe libperf.a file to ensure that it will consider every .o file in the\narchive, not just what it believes that it needs.

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
