perf-record both create a thread_map of threads to be\nmonitored. That map is used in perf_event__synthesize_thread_map which\nloops over the entries in thread_map and calls __event__synthesize_thread\nto generate COMM and MMAP events.\n\n__event__synthesize_thread calls perf_event__synthesize_comm which opens\n/proc/pid/status, reads the name of the task and its thread group id.\nThat\u0027s all fine. The problem is that it then reads /proc/pid/task and\ngenerates COMM events for each task it finds - but using the name found\nin /proc/pid/status where pid is the thread of interest.\n\nThe end result (looping over thread_map + synthesizing comm events for\neach thread each time) means the name of the last thread processed sets\nthe name for all threads in the process - which is not good for\nmultithreaded processes with named threads.\n\nThe Fix:\nperf_event__synthesize_comm has an input argument (full) that decides\nwhether to process task entries for each pid it is passed. It currently\nnever set to 0 (perf_event__synthesize_comm has a single caller and it\nalways passes the value 1). Let\u0027s fix that.\n\nAdd the full input argument to __event__synthesize_thread which passes\nit to perf_event__synthesize_comm. For thread/process monitoring set full\nto 0 which means COMM and MMAP events are only generated for the pid\npassed to it. For system wide monitoring set full to 1 so that COMM events\nare generated for all threads in a process.\n\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nLink: http://lkml.kernel.org/r/1324578603-12762-2-git-send-email-dsahern@gmail.com\nSigned-off-by: David Ahern \u003cdsahern@gmail.com\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "fb2baceb5a64990163e93b77ee205d0173202ee6", "tree": "707946ff30adece39d0a19f7f82d0522133e5c96", "parents": [ "f1ac18af219835fd5b8e19c14d2dd75c55f78737" ], "author": { "name": "Namhyung Kim", "email": "namhyung@gmail.com", "time": "Tue Dec 13 00:16:56 2011 +0900" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Thu Dec 22 10:23:55 2011 -0200" }, "message": "perf report: Fix usage string\n\nperf report does not take a command from command line.\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/1323703017-6060-8-git-send-email-namhyung@gmail.com\nSigned-off-by: Namhyung Kim \u003cnamhyung@gmail.com\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "f1ac18af219835fd5b8e19c14d2dd75c55f78737", "tree": "3cd2dfa81d3256c7b63040c6b0b687176a36fe30", "parents": [ "9c1497ea591b25d491f8e795f90a1405100b75ef" ], "author": { "name": "Stephane Eranian", "email": "eranian@google.com", "time": "Sun Dec 11 00:28:54 2011 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Dec 21 10:26:41 2011 +0100" }, "message": "perf: Add support for PERF_HW_COUNT_REF_CPU_CYCLES\n\nAdd new generic hw event: ref-cycles, which maps to\nPERF_HW_COUNT_REF_CPUCYCLES:\n\n $ perf stat -e ref-cycles ls\n\nSigned-off-by: Stephane Eranian \u003ceranian@google.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLink: http://lkml.kernel.org/r/1323559734-3488-5-git-send-email-eranian@google.com\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "d9e24427f339e5c18419769d41697062811c5cd8", "tree": "3c50f19561f60d4175d375ff8d39ec203a42eb8c", "parents": [ "d87f69a16eb2cb96459117b06949a560679002e4", "65c1e0452a3389f9b7b8c1b23305ed2922fafb2d" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Dec 20 20:32:37 2011 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Dec 20 20:32:37 2011 +0100" }, "message": "Merge branch \u0027perf/core\u0027 of git://github.com/acmel/linux into perf/core\n" }, { "commit": "d87f69a16eb2cb96459117b06949a560679002e4", "tree": "bbb55b2bd2b6c9e8bd4067aa3279783cb6bd9028", "parents": [ "124ba9403318d834ef21bcd899c22c870708d2c4", "384703b8e6cd4c8ef08512e596024e028c91c339" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Dec 20 20:32:03 2011 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Dec 20 20:32:11 2011 +0100" }, "message": "Merge commit \u0027v3.2-rc6\u0027 into perf/core\n\nMerge reason: Update with the latest fixes.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "65c1e0452a3389f9b7b8c1b23305ed2922fafb2d", "tree": "7e6408b8e3794e3c399577c49b68a0fa0ff43fcf", "parents": [ "cb8f4e9aa37c469ddd80dda51469f327606c0118" ], "author": { "name": "Jiri Olsa", "email": "jolsa@redhat.com", "time": "Thu Dec 15 16:30:39 2011 +0100" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Tue Dec 20 14:46:14 2011 -0200" }, "message": "perf test: Add more automated tests for event parsing\n\nAdding automated tests for event parsing to include testing for modifier\nand \u0027,\u0027 operator.\n\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: cjashfor@linux.vnet.ibm.com\nLink: http://lkml.kernel.org/r/1323963039-7602-4-git-send-email-jolsa@redhat.com\nSigned-off-by: Jiri Olsa \u003cjolsa@redhat.com\u003e\n[ committer note: Remove some tests that need group_leader \u0026 bison patchkits ]\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "cb8f4e9aa37c469ddd80dda51469f327606c0118", "tree": "89dd395f7d6008a354fa30d1037628c1d815415a", "parents": [ "5f9273d64a5ccbd3c2b4446cc8b71123ed5d6366" ], "author": { "name": "Namhyung Kim", "email": "namhyung@gmail.com", "time": "Tue Dec 13 00:16:55 2011 +0900" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Tue Dec 20 13:50:59 2011 -0200" }, "message": "perf events: Tidy up perf_event__preprocess_sample\n\nUse local variable \u0027dso\u0027 to reduce typing a bit and rearrange the if\ncondition.
