From e312bcf13053970c0f07ec2c02d7d9be1a036ce0 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Thu, 15 Sep 2016 15:24:53 -0700 Subject: [PATCH] perf tools: Make alias matching case-insensitive Make alias matching the events parser case-insensitive. This is useful with the JSON events. perf uses lower case events, but the CPU manuals generally use upper case event names. The JSON files use lower case by default too. But if we search case insensitively then users can cut-n-paste the upper case event names. So the following works: % perf stat -e BR_INST_EXEC.TAKEN_INDIRECT_NEAR_CALL true Performance counter stats for 'true': 305 BR_INST_EXEC.TAKEN_INDIRECT_NEAR_CALL 0.000492799 seconds time elapsed Signed-off-by: Andi Kleen Acked-by: Ingo Molnar Tested-by: Arnaldo Carvalho de Melo Cc: Madhavan Srinivasan Cc: Peter Zijlstra Cc: linuxppc-dev@lists.ozlabs.org Link: http://lkml.kernel.org/r/1473978296-20712-17-git-send-email-sukadev@linux.vnet.ibm.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/parse-events.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/perf/util/parse-events.c b/tools/perf/util/parse-events.c index d445b1144c87..4e778eae1510 100644 --- a/tools/perf/util/parse-events.c +++ b/tools/perf/util/parse-events.c @@ -1459,7 +1459,7 @@ comp_pmu(const void *p1, const void *p2) struct perf_pmu_event_symbol *pmu1 = (struct perf_pmu_event_symbol *) p1; struct perf_pmu_event_symbol *pmu2 = (struct perf_pmu_event_symbol *) p2; - return strcmp(pmu1->symbol, pmu2->symbol); + return strcasecmp(pmu1->symbol, pmu2->symbol); } static void perf_pmu__parse_cleanup(void) -- 2.20.1
