commit b25114817a73bbd2b84ce9dba02ee1ef8989a947\n perf build-id: Add quirk to deal with perf.data file format breakage\n\npopulates the \"struct build_id_event::pid\" with 0, which\nis later interpreted as DEFAULT_GUEST_KERNEL_ID.\n\nThis is not always correct, so it\u0027s better to guess the pid\nvalue based on the \"struct build_id_event::header::misc\" value.\n\n- Tested with data generated on x86 kernel version v2.6.34\n and reported back on x86_64 current kernel.\n- Not tested for guest kernel case.\n\nNote the problem stays for PERF_RECORD_MMAP events recorded by perf that\ndoes not use proper pid (HOST_KERNEL_ID/DEFAULT_GUEST_KERNEL_ID). They are\nmisinterpreted within the current perf code. Probably there\u0027s not much we\ncan do about that.\n\nCc: Avi Kivity \u003cavi@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Yanmin Zhang \u003cyanmin_zhang@linux.intel.com\u003e\nLink: http://lkml.kernel.org/r/20110601194346.GB1934@jolsa.brq.redhat.com\nSigned-off-by: Jiri Olsa \u003cjolsa@redhat.com\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "fc8ed7be738ffb1b3b0140ed2de6def38b9a7101", "tree": "756a46bd805d24a36176987d553928b3defa2b41", "parents": [ "981c1252691f4b855f2bb47ea93fb6052ea3aee2" ], "author": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Wed Aug 10 12:42:26 2011 -0300" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Wed Aug 10 12:42:26 2011 -0300" }, "message": "perf top browser: Remove spurious helpline update\n\nIt will be immediately replaced in perf_top_browser__run.\n\nCc: David Ahern \u003cdsahern@gmail.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\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\nLink: http://lkml.kernel.org/n/tip-q7e2jzb44elqpkvdllk94x0i@git.kernel.org\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "7676ebbaf21c3828e6315baadb6fcde448aa79b4", "tree": "f940029a96b3d82b84a4433d1e2b917ff1d2b166", "parents": [ "e710574de10b181c159a67af75af0245de33a4b9", "981c1252691f4b855f2bb47ea93fb6052ea3aee2" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Aug 10 10:20:52 2011 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Aug 10 10:20:52 2011 +0200" }, "message": "Merge branch \u0027perf/core\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent\n" }, { "commit": "981c1252691f4b855f2bb47ea93fb6052ea3aee2", "tree": "7cb1acf6cbaf11c1baf3a474c891a4798a8bbcda", "parents": [ "580cabed88ebc631e740b16010f2fa6ba882652f" ], "author": { "name": "Pekka Enberg", "email": "penberg@kernel.org", "time": "Tue Aug 09 22:54:18 2011 +0300" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Tue Aug 09 15:23:08 2011 -0300" }, "message": "perf symbols: Check \u0027/tmp/perf-\u0027 symbol file ownership\n\nThe external symbol files are generated by JIT compilers, for example, but we\nneed to make sure they\u0027re ours before injecting them to \u0027perf report\u0027.\n\nRequested-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nLink: http://lkml.kernel.org/r/1312919658-17158-1-git-send-email-penberg@kernel.org\nSigned-off-by: Pekka Enberg \u003cpenberg@kernel.org\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "580cabed88ebc631e740b16010f2fa6ba882652f", "tree": "4a62164f6936927bbc1b41681dff3cf7bb2638be", "parents": [ "4c09bafae37d870ab8efc50faeeb4855cb55b5b7" ], "author": { "name": "Jiri Olsa", "email": "jolsa@redhat.com", "time": "Tue Aug 09 14:46:51 2011 +0200" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Tue Aug 09 13:32:12 2011 -0300" }, "message": "perf sched: Usage leftover from trace -\u003e script rename\n\nThe \u0027perf sched\u0027 command usage still showing \u0027trace\u0027 command instead of\nthe \u0027script\u0027 command.\n\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLink: http://lkml.kernel.org/r/20110809124651.GD2056@jolsa.brq.redhat.com\nSigned-off-by: Jiri Olsa \u003cjolsa@redhat.com\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "4c09bafae37d870ab8efc50faeeb4855cb55b5b7", "tree": "9e750321369285dec47289fe4af8acd221140c0d", "parents": [ "069e3725dd9be3b759a98e8c80ac5fc38b392b23" ], "author": { "name": "Jiri Olsa", "email": "jolsa@redhat.com", "time": "Mon Aug 08 23:03:34 2011 +0200" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Tue Aug 09 13:31:38 2011 -0300" }, "message": "perf sched: Do not delete session object prematurely\n\nThe session object is released prematurely when processing events for\nlatency command.
