I rebased this one and made some other fixes so that I could test it, so I thought I'd repost it here in case it's helpful. I also added a new test. But for the testing it all looks ok. There is one small difference where it now hides _all_ default <not supported> events, when previously it would only hide some selected subset of events like "stalled-cycles-frontend". I think this is now more consistent across platforms because, for example, Apple M only has cycles and instructions, and the rest of the default events would always show as <not supported> there. Tested on Raptor Lake, Kaby Lake, Juno, N1, Ampere (with the DSU cycles PMU) and I also faked an Apple M on Juno. Changes since v6: * Fix empty PMU name in perf report * Rebase onto perf-tools-next 003265bb6f02 Changes since v5: * Test on x86 non hybrid * Assume 1 PMU in the test when no PMUs expose /cpus file Changes since v4: * Hide all <not supported> default events when not verbose * Remove previous note about <not supported> behavior from the cover letter and replace it with a new note about the new behavior Changes since v3: * Rebase onto perf-tools-next 6236ebe07 * Fix Intel TPEBS counting mode test * Fix arm-spe build * Add support for DT devices in stat test * Add a new test for hybrid perf stat default arguments Ian Rogers (5): perf evsel: Add alternate_hw_config and use in evsel__match perf stat: Uniquify event name improvements perf stat: Remove evlist__add_default_attrs use strings perf evsel x86: Make evsel__has_perf_metrics work for legacy events perf evsel: Remove pmu_name James Clark (2): perf test: Make stat test work on DT devices perf test: Add a test for default perf stat command tools/perf/arch/arm64/util/arm-spe.c | 4 +- tools/perf/arch/x86/util/evlist.c | 74 +---- tools/perf/arch/x86/util/evsel.c | 35 ++- tools/perf/builtin-diff.c | 6 +- tools/perf/builtin-stat.c | 291 +++++++----------- tools/perf/tests/parse-events.c | 2 +- tools/perf/tests/shell/stat.sh | 37 ++- .../perf/tests/shell/test_stat_intel_tpebs.sh | 11 +- tools/perf/util/evlist.c | 46 +-- tools/perf/util/evlist.h | 12 - tools/perf/util/evsel.c | 28 +- tools/perf/util/evsel.h | 22 +- tools/perf/util/metricgroup.c | 4 +- tools/perf/util/parse-events.c | 57 ++-- tools/perf/util/parse-events.h | 8 +- tools/perf/util/parse-events.y | 2 +- tools/perf/util/pmu.c | 6 +- tools/perf/util/pmu.h | 2 +- tools/perf/util/stat-display.c | 109 +++++-- tools/perf/util/stat-shadow.c | 14 +- tools/perf/util/stat.c | 2 +- 21 files changed, 359 insertions(+), 413 deletions(-)
