The tests were passing but without testing and were printing the
following:
$ ./perf test -v 90
90: perf all PMU test :
--- start ---
test child forked, pid 51650
Testing cpu/branch-instructions/
./tests/shell/stat_all_pmu.sh: 10: [:
Performance counter stats for 'true':
137,307 cpu/branch-instructions/
0.001686672 seconds time elapsed
0.001376000 seconds user
0.000000000 seconds sys: unexpected operator
Changing the regexes to a grep works in sh and prints this:
$ ./perf test -v 90
90: perf all PMU test :
--- start ---
test child forked, pid 60186
[...]
Testing tlb_flush.stlb_any
test child finished with 0
---- end ----
perf all PMU test: Ok
