perf tests: Add test to check for event times
This test creates software event 'cpu-clock' attaches it in several ways
and checks that enabled and running times match.
Committer notes:
Testing it:
[acme@jouet linux]$ perf test -v times
44: Test events times :
--- start ---
test child forked, pid 27170
attaching to spawned child, enable on exec
OK : ena 307328, run 307328
attaching to current thread as enabled
OK : ena 7826, run 7826
attaching to current thread as disabled
OK : ena 738, run 738
attaching to CPU 0 as enabled
SKIP : not enough rights
attaching to CPU 0 as enabled
SKIP : not enough rights
test child finished with -2
---- end ----
Test events times: Skip
