From c8d6828a6510c9363180ebf662b51d032e0eb85a Mon Sep 17 00:00:00 2001 From: Sukadev Bhattiprolu Date: Thu, 15 Sep 2016 15:24:48 -0700 Subject: perf list: Support long jevents descriptions Previously we were dropping the useful longer descriptions that some events have in the event list completely. This patch makes them appear with perf list. Old perf list: baclears: baclears.all [Counts the number of baclears] vs new: perf list -v: ... baclears: baclears.all [The BACLEARS event counts the number of times the front end is resteered, mainly when the Branch Prediction Unit cannot provide a correct prediction and this is corrected by the Branch Address Calculator at the front end. The BACLEARS.ANY event counts the number of baclears for any type of branch] Signed-off-by: Andi Kleen Signed-off-by: Sukadev Bhattiprolu Acked-by: Ingo Molnar Acked-by: Jiri Olsa Cc: Madhavan Srinivasan Cc: Peter Zijlstra Cc: linuxppc-dev@lists.ozlabs.org Link: http://lkml.kernel.org/r/1473978296-20712-13-git-send-email-sukadev@linux.vnet.ibm.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/pmu.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'tools/perf/util/pmu.h') diff --git a/tools/perf/util/pmu.h b/tools/perf/util/pmu.h index 7b47192e03b5..2fb8aa0fb47f 100644 --- a/tools/perf/util/pmu.h +++ b/tools/perf/util/pmu.h @@ -41,6 +41,7 @@ struct perf_pmu_info { struct perf_pmu_alias { char *name; char *desc; + char *long_desc; struct list_head terms; /* HEAD struct parse_events_term -> list */ struct list_head list; /* ELEM */ char unit[UNIT_MAX_LEN+1]; @@ -72,7 +73,8 @@ int perf_pmu__format_parse(char *dir, struct list_head *head); struct perf_pmu *perf_pmu__scan(struct perf_pmu *pmu); -void print_pmu_events(const char *event_glob, bool name_only, bool quiet); +void print_pmu_events(const char *event_glob, bool name_only, bool quiet, + bool long_desc); bool pmu_have_event(const char *pname, const char *name); int perf_pmu__scan_file(struct perf_pmu *pmu, const char *name, const char *fmt, -- cgit v1.2.3-59-g8ed1b
