It basically traverses the hardware and software event name arrays creating an evlist with all events, then it uses perf_evsel__name to check that the name is the expected one. With it I noticed this problem: [root@sandy ~]# perf test 10 10: roundtrip evsel->name check:invalid or unsupported event: 'CPU-migrations' Run 'perf list' for a list of valid events FAILED! Changed it to "cpu-migrations" in the software event arrays and it worked. This is to catch problems like the one reported by Joel Uckelman in http://permalink.gmane.org/gmane.linux.kernel.perf.user/1016 Hardware cache events will be checked in the following patch.
