Hello My student noticed that when she accidentally cut and pasted an invalid event it was being accepted as valid by libpfm4/PAPI.
The event in question is two events stuck together with a comma. I think the second event is somehow being treated as an invalid umask and ignored. The event in this case is on Skylake: "DTLB_LOAD_MISSES:MISS_CAUSES_A_WALK,DTLB_STORE_MISSES:MISS_CAUSES_A_WALK:u=1" For example. running this: ./check_events DTLB_LOAD_MISSES:MISS_CAUSES_A_WALK,DTLB_STORE_MISSES:MISS_CAUSES_A_WALK:u=1 Requested Event: DTLB_LOAD_MISSES:MISS_CAUSES_A_WALK,DTLB_STORE_MISSES:MISS_CAUSES_A_WALK:u=1 Actual Event: skl::DTLB_LOAD_MISSES:MISS_CAUSES_A_WALK:k=1:u=1:e=0:i=0:c=0:t=0:intx=0:intxcp=0 PMU : Intel Skylake IDX : 419430412 Codes : 0x530108 where it should probably return some sort of error?
