I'm not fully sure what first wildcard match is. That means just
matching on the name? FWIW I think it's ok for common cases, but there
are definitely also cases where the same event doesn't quite mean the
same on hybrid cores.
but anyways as long as it works for "cycles" it's fine because
that's nearly everyone uses with perf top.
