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.

      "message": "perf: Fix endianness argument compatibility with OPT_BOOLEAN() and introduce OPT_INCR()\n\nParsing an option from the command line with OPT_BOOLEAN on a\nbool data type would not work on a big-endian machine due to the\nmanner in which the boolean was being cast into an int and\nincremented. For example, running \u0027perf probe --list\u0027 on a\nPowerPC machine would fail to properly set the list_events bool\nand would therefore print out the usage information and\nterminate.\n\nThis patch makes OPT_BOOLEAN work as expected with a bool\ndatatype. For cases where the original OPT_BOOLEAN was\nintentionally being used to increment an int each time it was\npassed in on the command line, this patch introduces OPT_INCR\nwith the old behaviour of OPT_BOOLEAN (the verbose variable is\ncurrently the only such example of this).\n\nI have reviewed every use of OPT_BOOLEAN to verify that a true\nC99 bool was passed. Where integers were used, I verified that\nthey were only being used for boolean logic and changed them to\nbools to ensure that they would not be mistakenly used as ints.\nThe major exception was the verbose variable which now uses\nOPT_INCR instead of OPT_BOOLEAN.\n\nSigned-off-by: Ian Munsie \u003cimunsie@au.ibm.com\u003e\nAcked-by: David S.

Look for\n    adjust_symbols handling in dso__load_sym()\n\nPreviously we were always unmapping sym-\u003estart and for ET_DYN\ndsos resulting addresses were wrong, and so objdump output was\nempty.\n\nThe end result was that perf annotate output for symbols from\nnon-prelinked *.so had always 0.00% percents only, which is\nwrong.\n\nTo fix it, let\u0027s introduce a helper for converting rip to\nobjdump address, and also let\u0027s document what map_ip() and\nunmap_ip() do -- I had to study sources for several hours to\nunderstand it.\n\nSigned-off-by: Kirill Smelkov \u003ckirr@landau.phys.spbu.ru\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nLKML-Reference: \u003c1265223128-11786-8-git-send-email-acme@infradead.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"
