2025-05-28perf test trace_summary: Skip --bpf-summary tests if no libbpfIan Rogers
If perf is built without libbpf (e.g. NO_LIBBPF=1) then the --bpf-summary perf trace tests will fail. Skip the tests as this is expected behavior.

2025-05-22perf tests trace_summary.sh: Run in exclusive modeArnaldo Carvalho de Melo
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 <adrian.hunter@intel.com> Cc: Howard Chu <howardchu95@gmail.com> Cc: Ian Rogers <irogers@google.com> Cc: James Clark <james.clark@linaro.org> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lore.kernel.org/r/aC-hHTgArwlF_zu9@x1 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
