perf script: Print callchains and symbols if they exist The intent of perf-script is to dump the events and information in the file. H/W, S/W and raw events all dump callchains if they are present; might as well make that the default for tracepoints too. v2: Only add options for sym, dso and ip if callchains are present Signed-off-by: David Ahern <dsah...@gmail.com> Cc: Frederic Weisbecker <fweis...@gmail.com> Link: http://lkml.kernel.org/r/1384920457-5986-1-git-send-email-dsah...@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <a...@redhat.com> --- tools/perf/builtin-script.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) diff --git a/tools/perf/builtin-script.c b/tools/perf/builtin-script.c index b392770..9f3ba44 100644 --- a/tools/perf/builtin-script.c +++ b/tools/perf/builtin-script.c @@ -280,6 +280,30 @@ static int perf_session__check_output_opt(struct perf_session *session) set_print_ip_opts(&evsel->attr); } + /* + * set default for tracepoints to print symbols only + * if callchains are present + */ + if (symbol_conf.use_callchain && + !output[PERF_TYPE_TRACEPOINT].user_set) { + struct perf_event_attr *attr; + + j = PERF_TYPE_TRACEPOINT; + evsel = perf_session__find_first_evtype(session, j); + if (evsel == NULL) + goto out; + + attr = &evsel->attr; + + if (attr->sample_type & PERF_SAMPLE_CALLCHAIN) { + output[j].fields |= PERF_OUTPUT_IP; + output[j].fields |= PERF_OUTPUT_SYM; + output[j].fields |= PERF_OUTPUT_DSO; + set_print_ip_opts(attr); + } + } + +out: return 0; } -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
