Thanks, I'm also seeing some weirdness in the perf all metrics and
metricsgroups tests with verbose output:

95: perf all metrics test :
Skip
.../perf-tools-next/tools/perf# ./perf test 95 -vvv

The * is getting replaced with the files in my working directory, which
is tools/perf, but only when running 'perf test', running 'perf stat'
just prints the error normally:
.../perf-tools-next/tools/perf# ./perf stat -M tma_fp_scalar sleep 1
Cannot resolve IDs for tma_fp_scalar: FP_ARITH_INST_RETIRED.SCALAR /
