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
