Instead, when perf is not compiled with libtraceevent support, skip those tests instead of failing them, by checking the output of `perf record --dry-run` to see if it prints the error "libtraceevent is necessary for tracepoint support" For the following output, perf compiled with: `make NO_LIBTRACEEVENT=1` Before the patch: 108: perf script task-analyzer tests : test child forked, pid 24105 failed to open perf.data: No such file or directory (try 'perf record' first) FAIL: "invokation of perf script report task-analyzer command failed" Error message: "" FAIL: "test_basic" Error message: "Failed to find required string:'Comm'." failed to open perf.data: No such file or directory (try 'perf record' first) FAIL: "invokation of perf script report task-analyzer --ns --rename-comms-by-tids 0:random command failed" Error message: "" FAIL: "test_ns_rename" Error message: "Failed to find required string:'Comm'." failed to open perf.data: No such file or directory (try 'perf record' first) <...> perf script task-analyzer tests: FAILED! With this patch, the script instead returns 2 signifying SKIP, and after the patch: 108: perf script task-analyzer tests : test child forked, pid 26010 libtraceevent is necessary for tracepoint support WARN: Skipping tests. No libtraceevent support test child finished with -2 perf script task-analyzer tests: Skip Fixes: e8478b84d6ba9ccf ("perf test: Add new task-analyzer tests") Signed-off-by: Aditya Gupta Cc: Disha Goel Cc: Ian Rogers Cc: Jiri Olsa Cc: John Garry Cc: Madhavan Srinivasan Cc: Namhyung Kim Cc: Petar Gligoric Cc: Ravi Bangoria Cc: linuxppc-dev@lists.ozlabs.org Link: https://lore.kernel.org/r/20230613164145.50488-18-atrajeev@linux.vnet.ibm.com Signed-off-by: Athira Rajeev Signed-off-by: Kajol Jain Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: Sasha Levin --- tools/perf/tests/shell/test_task_analyzer.sh | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/tools/perf/tests/shell/test_task_analyzer.sh b/tools/perf/tests/shell/test_task_analyzer.sh index 6b3343234a6b2..1b7f3c1ec218b 100755 --- a/tools/perf/tests/shell/test_task_analyzer.sh +++ b/tools/perf/tests/shell/test_task_analyzer.sh @@ -44,9 +44,20 @@ find_str_or_fail() { fi } +# check if perf is compiled with libtraceevent support +skip_no_probe_record_support() { + perf record -e "sched:sched_switch" -a -- sleep 1 2>&1 | grep "libtraceevent is necessary for tracepoint support" && return 2 + return 0 +} + prepare_perf_data() { # 1s should be sufficient to catch at least some switches perf record -e sched:sched_switch -a -- sleep 1 > /dev/null 2>&1 + # check if perf data file got created in above step. + if [ ! -e "perf.data" ]; then + printf "FAIL: perf record failed to create \"perf.data\" \n" + return 1 + fi } # check standard inkvokation with no arguments @@ -134,6 +145,13 @@ test_csvsummary_extended() { find_str_or_fail "Out-Out;" csvsummary ${FUNCNAME[0]} } +skip_no_probe_record_support +err=$? +if [ $err -ne 0 ]; then + echo "WARN: Skipping tests.
