From: Andi Kleen <a...@linux.intel.com> Synthesize the per attr thread maps and cpu maps in 'perf record'.
This allows code from 'perf stat' called from 'perf script' to access this information. Committer testing: Please see the PERF_RECORD_THREAD_MAP and PERF_RECORD_CPU_MAP records, added by this patch: $ perf record sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.001 MB perf.data (8 samples) ] $ perf report -D | grep PERF_RECORD_ | head 0xe8 [0x20]: PERF_RECORD_TIME_CONV: unhandled! 0x108 [0x28]: PERF_RECORD_THREAD_MAP nr: 1 thread: 23568 0x130 [0x18]: PERF_RECORD_CPU_MAP: 0-3 0 0x148 [0x28]: PERF_RECORD_COMM: perf:23568/23568 0x570 [0x8]: PERF_RECORD_FINISHED_ROUND 445342677837144 0x170 [0x28]: PERF_RECORD_COMM exec: sleep:23568/23568 445342677847339 0x198 [0x68]: PERF_RECORD_MMAP2 23568/23568: [0x564c943a4000(0x208000) @ 0 fd:00 3147174 2566255743]: r-xp /usr/bin/sleep 445342677862450 0x200 [0x70]: PERF_RECORD_MMAP2 23568/23568: [0x7f25968a8000(0x229000) @ 0 fd:00 3151761 2566238119]: r-xp /usr/lib64/ld-2.25.so 445342677873174 0x270 [0x60]: PERF_RECORD_MMAP2 23568/23568: [0x7ffc98176000(0x2000) @ 0 00:00 0 0]: r-xp [vdso] 445342677891928 0x2d0 [0x28]: PERF_RECORD_SAMPLE(IP, 0x4002): 23568/23568: 0xffffffff8f84c7e7 period: 1 addr: 0 $ Signed-off-by: Andi Kleen <a...@linux.intel.com> Acked-by: Jiri Olsa <jo...@kernel.org> Tested-by: Arnaldo Carvalho de Melo <a...@redhat.com> Link: http://lkml.kernel.org/r/20171117214300.32746-3-a...@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo <a...@redhat.com> --- tools/perf/builtin-record.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/tools/perf/builtin-record.c b/tools/perf/builtin-record.c index b92d6d67bca8..e304bc47fe9b 100644 --- a/tools/perf/builtin-record.c +++ b/tools/perf/builtin-record.c @@ -793,6 +793,21 @@ static int record__synthesize(struct record *rec, bool tail) if (err) goto out; + err = perf_event__synthesize_thread_map2(&rec->tool, rec->evlist->threads, + process_synthesized_event, + NULL); + if (err < 0) { + pr_err("Couldn't synthesize thread map.\n"); + return err; + } + + err = perf_event__synthesize_cpu_map(&rec->tool, rec->evlist->cpus, + process_synthesized_event, NULL); + if (err < 0) { + pr_err("Couldn't synthesize cpu map.\n"); + return err; + } + err = __machine__synthesize_threads(machine, tool, &opts->target, rec->evlist->threads, process_synthesized_event, opts->sample_address, opts->proc_map_timeout, 1); -- 2.13.6
