Applied, but then I tried: [acme@zoo linux]$ perf evlist -v cycles: sample_freq=4000, size: 96, sample_type: IP|TID|TIME|CALLCHAIN|PERIOD, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1, enable_on_exec: 1, sample_id_all: 1, exclude_guest: 1 [acme@zoo linux]$ I.e. using the tool that provides info about 'perf.data' files, and there I couldn't figure it out which kind of callchains was used, can you fix it there too? - Arnaldo > Signed-off-by: Jiri Olsa <[email protected]> > Cc: Corey Ashford <[email protected]> > Cc: David Ahern <[email protected]> > Cc: Ingo Molnar <[email protected]> > Cc: Namhyung Kim <[email protected]> > Cc: Paul Mackerras <[email protected]> > Cc: Peter Zijlstra <[email protected]> > Cc: Arnaldo Carvalho de Melo <[email protected]> > Cc: Andi Kleen <[email protected]> > Cc: Adrian Hunter <[email protected]> > --- > tools/perf/builtin-record.c | 4 +++- > tools/perf/perf.h | 3 ++- > 2 files changed, 5 insertions(+), 2 deletions(-) > > diff --git a/tools/perf/builtin-record.c b/tools/perf/builtin-record.c > index 3f7ec8a..679758f 100644 > --- a/tools/perf/builtin-record.c > +++ b/tools/perf/builtin-record.c > @@ -741,7 +741,9 @@ int record_parse_callchain(const char *arg, struct > record_opts *opts) > > static void callchain_debug(struct record_opts *opts) > { > - pr_debug("callchain: type %d\n", opts->call_graph); > + static const char *str[CALLCHAIN_MAX] = { "NONE", "FP", "DWARF" }; > + > + pr_debug("callchain: type %s\n", str[opts->call_graph]); > > if (opts->call_graph == CALLCHAIN_DWARF) > pr_debug("callchain: stack dump size %d\n", > diff --git a/tools/perf/perf.h b/tools/perf/perf.h > index 6dabc15..c30e1ae 100644 > --- a/tools/perf/perf.h > +++ b/tools/perf/perf.h > @@ -251,7 +251,8 @@ void pthread__unblock_sigwinch(void); > enum perf_call_graph_mode { > CALLCHAIN_NONE, > CALLCHAIN_FP, > - CALLCHAIN_DWARF > + CALLCHAIN_DWARF, > + CALLCHAIN_MAX > }; > > struct record_opts { > -- > 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
