From 9e893dab828577adb166cc2badfb4711f1cd6e4c Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 22 May 2025 19:01:47 -0300 Subject: [PATCH] perf tests trace_summary.sh: Run in exclusive mode And it is being successfull only when running alone, probably because there are some tests that add the vfs_getname probe that gets used by 'perf trace' and alter how it does syscall arg pathname resolution. This should be removed or made a fallback to the preferred BPF mode of getting syscall parameters, but till then, run this in exclusive mode. For reference, here are some of the tests that run close to this one: 127: perf record offcpu profiling tests : Ok 128: perf all PMU test : Ok 129: perf stat --bpf-counters test : Ok 130: Check Arm CoreSight trace data recording and synthesized samples: Skip 131: Check Arm CoreSight disassembly script completes without errors : Skip 132: Check Arm SPE trace data recording and synthesized samples : Skip 133: Test data symbol : Ok 134: Miscellaneous Intel PT testing : Skip 135: test Intel TPEBS counting mode : Skip 136: perf script task-analyzer tests : Ok 137: Check open filename arg using perf trace + vfs_getname : Ok 138: perf trace summary : Ok Cc: Adrian Hunter Cc: Howard Chu Cc: Ian Rogers Cc: James Clark Cc: Jiri Olsa Cc: Kan Liang Cc: Namhyung Kim Link: https://lore.kernel.org/r/aC-hHTgArwlF_zu9@x1 Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/tests/shell/trace_summary.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/perf/tests/shell/trace_summary.sh b/tools/perf/tests/shell/trace_summary.sh index bb350dfabdc2b..49766524dc21b 100755 --- a/tools/perf/tests/shell/trace_summary.sh +++ b/tools/perf/tests/shell/trace_summary.sh @@ -1,5 +1,5 @@ #!/bin/sh -# perf trace summary +# perf trace summary (exclusive) # SPDX-License-Identifier: GPL-2.0 # Check that perf trace works with various summary mode -- 2.39.5
