perf test all metrics: Fully ignore Default metric failures

2025-11-20T19:08:46Z

Determine if a metric is default from `perf list --raw-dump $m` eg: ``` $ perf list --raw-dump l1_prefetch_miss_rate Default4 l1_prefetch_miss_rate ``` If a metric has "not supported" or "no supported events" then ignore these failures for default metrics. Tidy up the skip/fail messages in the output to make them easier to spot/read. ``` $ perf list -vv "all metrics" ... Testing llc_miss_rate [Ignored llc_miss_rate] failed but as a Default metric this can be expected Error: No supported events found. The LLC-loads event is not supported. ... ``` Reported-by: Thomas Richter Closes: https://lore.kernel.org/linux-perf-users/20251119104751.51960-1-tmricht@linux.ibm.com/ Reported-by: Namhyung Kim Reported-by: James Clark Closes: https://lore.kernel.org/lkml/aRi9xnwdLh3Dir9f@google.com/ Signed-off-by: Ian Rogers Reviewed-by: James Clark Tested-by: Thomas Richter Signed-off-by: Namhyung Kim

perf test metrics: Update all metrics for possibly failing default metrics

2025-11-12T00:48:35Z

Default metrics may use unsupported events and be ignored. These metrics shouldn't cause metric testing to fail. Signed-off-by: Ian Rogers Signed-off-by: Namhyung Kim

perf tests metrics: Permission related fixes

2025-05-12T17:18:16Z

When permissions are limited running sleep without system wide isn't a good benchmark to run to achieve samples, switch to running noploop. Remove indent for non-success cases. Allow skip for the not counted case. Minor debug changes.

perf test: Update all metrics test like metricgroups test

2024-10-19T16:34:56Z

Like in the metricgroup tests, it should check the permission first and then skip relevant failures accordingly. Also it needs to try again with the system wide flag properly. On the second round, check if the result has the metric name because other failure cases are checked in the first round already.

perf tests stat_all_metrics: Change true workload to sleep workload for system wide check

Testcase stat_all_metrics.sh fails in powerpc: 98: perf all metrics test : FAILED!

This change happened after the commit a4b8cfcabb1d90ec ("perf stat: Delay metric parsing"), which delayed the metric parsing phase and now before metric parsing phase perf tool identifies, whether target is system-wide or not. With this change, perf_event_open will fails with workload monitoring for uncore events as expected. The perf all metric test case fails as some of the hv-24x7 metric events may need bigger workload with system wide monitoring to get the data. Fix this issue by changing current system wide check from true workload to sleep 0.01 workload.

perf test: Make all metrics test more tolerant

2022-07-12T11:54:47Z

Metric names are truncated so don't try to match all of one. Allow AMX metrics to skip as floating point ones do. Metrics for optane memory can also skip rather than fail. Add a system wide check for uncore metrics. Restructure code to avoid extensive nesting.

perf test: Allow skip for all metrics test

2022-02-15T00:04:20Z

Some Intel TMA metrics compute a ratio that may divide by 0, which causes the metric not to print. This happens for metrics with FP_ARITH events. If we see these events in the result and would otherwise fail, then switch to a skip. Also, don't early exit when processing metrics.

perf test: Workload test of metric and metricgroups

2021-09-28T18:43:49Z

Test every metric and metricgroup with 'true' as a workload. For metrics, check that we see the metric printed or get unsupported. If the 'true' workload executes too quickly retry with 'perf bench internals synthesize'. v3. Fix test condition (thanks to Paul A. Clarke ). Add a fallback case of a larger workload so that we don't ignore "". v2. Switched the workload to something faster.
