From fa52ceabc2a3e70431a82bca2bc547a15eaf19df Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 2 Oct 2015 15:28:16 -0300 Subject: [PATCH] perf list: Honour 'event_glob' whem printing selectable PMUs Some PMUs, like the 'intel_bts' one can be used as an event name, i.e.: $ perf record -e intel_bts:// usleep 1 Is a valid event name. But the code printing such PMUs was not honouring the 'event_glob' parameter, so the following line was always appearing: $ intel_bts// [Kernel PMU event] Fix it: $ [acme@felicio linux]$ perf list data List of pre-defined events (to be used in -e): uncore_imc/data_reads/ [Kernel PMU event] uncore_imc/data_writes/ [Kernel PMU event] $ Cc: Adrian Hunter Cc: Borislav Petkov Cc: David Ahern Cc: Frederic Weisbecker Cc: Jiri Olsa Cc: Namhyung Kim Cc: Stephane Eranian Link: http://lkml.kernel.org/n/tip-ajb71858n7q7ao77b8pyy74w@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/pmu.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/tools/perf/util/pmu.c b/tools/perf/util/pmu.c index 41a356ba3cfe..e4b173dec4b9 100644 --- a/tools/perf/util/pmu.c +++ b/tools/perf/util/pmu.c @@ -1008,7 +1008,8 @@ void print_pmu_events(const char *event_glob, bool name_only) goto out_enomem; j++; } - if (pmu->selectable) { + if (pmu->selectable && + (event_glob == NULL || strglobmatch(pmu->name, event_glob))) { char *s; if (asprintf(&s, "%s//", pmu->name) < 0) goto out_enomem; -- 2.20.1
