From: Thomas Richter <tmricht@xxxxxxxxxxxxx> [ Upstream commit 9ef0112442bdddef5fb55adf20b3a5464b33de75 ] Perf test 40 for example has several subtests numbered 1-4 when displaying the start of the subtest. When the subtest results are displayed the subtests are numbered 0-3. Use this command to generate trace output: [root@s35lp76 perf]# ./perf test -Fv 40 2>/tmp/bpf1 Fix this by adjusting the subtest number when show the subtest result. Output before: [root@s35lp76 perf]# egrep '(^40\.[0-4]| subtest [0-4]:)' /tmp/bpf1 40.1: Basic BPF filtering : BPF filter subtest 0: Ok 40.2: BPF pinning : BPF filter subtest 1: Ok 40.3: BPF prologue generation : BPF filter subtest 2: Ok 40.4: BPF relocation checker : BPF filter subtest 3: Ok [root@s35lp76 perf]# Output after: root@s35lp76 ~]# egrep '(^40\.[0-4]| subtest [0-4]:)' /tmp/bpf1 40.1: Basic BPF filtering : BPF filter subtest 1: Ok 40.2: BPF pinning : BPF filter subtest 2: Ok 40.3: BPF prologue generation : BPF filter subtest 3: Ok 40.4: BPF relocation checker : BPF filter subtest 4: Ok [root@s35lp76 ~]# Signed-off-by: Thomas Richter <tmricht@xxxxxxxxxxxxx> Reviewed-by: Hendrik Brueckner <brueckner@xxxxxxxxxxxxx> Cc: Heiko Carstens <heiko.carstens@xxxxxxxxxx> Cc: Martin Schwidefsky <schwidefsky@xxxxxxxxxx> Link: http://lkml.kernel.org/r/20180724134858.100644-1-tmricht@xxxxxxxxxxxxx Signed-off-by: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx> Signed-off-by: Sasha Levin <alexander.levin@xxxxxxxxxxxxx> --- tools/perf/tests/builtin-test.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/perf/tests/builtin-test.c b/tools/perf/tests/builtin-test.c index 778668a2a966..ade7213943ad 100644 --- a/tools/perf/tests/builtin-test.c +++ b/tools/perf/tests/builtin-test.c @@ -413,7 +413,7 @@ static int __cmd_test(int argc, const char *argv[], struct intlist *skiplist) for (subi = 0; subi < subn; subi++) { pr_info("%2d.%1d: %-*s:", i, subi + 1, subw, t->subtest.get_desc(subi)); - err = test_and_print(t, skip, subi); + err = test_and_print(t, skip, subi + 1); if (err != TEST_OK && t->subtest.skip_if_fail) skip = true; } -- 2.17.1
