perf tests: Give a bit more information on the CQM test failure path
Before:
$ perf test -v cqm 48: Test intel cqm nmi context read : --- start --- test child forked, pid 1681 parse_events failed test child finished with -2 ---- end ---- Test intel cqm nmi context read: Skip $
After:
$ perf test -v cqm 48: Test intel cqm nmi context read : --- start --- test child forked, pid 1681 parse_events failed, is "intel_cqm/llc_occupancy/" available? test child finished with -2 ---- end ---- Test intel cqm nmi context read: Skip $
