From 13e741b834538a225512912608f0182079fc64e2 Mon Sep 17 00:00:00 2001 From: German Gomez Date: Mon, 21 Feb 2022 17:17:06 +0000 Subject: perf script: Fix error when printing 'weight' field In SPE traces the 'weight' field can't be printed in 'perf script' because the 'dummy:u' event doesn't have the WEIGHT attribute set. Use evsel__do_check_stype(..) to check this field, as it's done with other fields such as "phys_addr". Before: $ perf record -e arm_spe_0// -- sleep 1 $ perf script -F event,ip,weight Samples for 'dummy:u' event do not have WEIGHT attribute set. Cannot print 'weight' field. After: $ perf script -F event,ip,weight l1d-access: 12 ffffaf629d4cb320 tlb-access: 12 ffffaf629d4cb320 memory: 12 ffffaf629d4cb320 Fixes: b0fde9c6e291e528 ("perf arm-spe: Add SPE total latency as PERF_SAMPLE_WEIGHT") Signed-off-by: German Gomez Acked-by: Jiri Olsa Cc: Alexander Shishkin Cc: Mark Rutland Cc: Namhyung Kim Link: https://lore.kernel.org/r/20220221171707.62960-1-german.gomez@arm.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/builtin-script.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'tools/perf/builtin-script.c') diff --git a/tools/perf/builtin-script.c b/tools/perf/builtin-script.c index abae8184e171..fa478ddcd18a 100644 --- a/tools/perf/builtin-script.c +++ b/tools/perf/builtin-script.c @@ -463,7 +463,7 @@ static int evsel__check_attr(struct evsel *evsel, struct perf_session *session) return -EINVAL; if (PRINT_FIELD(WEIGHT) && - evsel__check_stype(evsel, PERF_SAMPLE_WEIGHT_TYPE, "WEIGHT", PERF_OUTPUT_WEIGHT)) + evsel__do_check_stype(evsel, PERF_SAMPLE_WEIGHT_TYPE, "WEIGHT", PERF_OUTPUT_WEIGHT, allow_user_set)) return -EINVAL; if (PRINT_FIELD(SYM) && -- cgit
