if(PAPI_event_name_to_code((char*)"perf::L1-DCACHE-LOADS",&eventId)!=PAPI_OK)printf("Err1");
PAPI_add_event(EventSet,eventId);
if(PAPI_event_name_to_code((char*)"perf::L1-DCACHE-LOAD-MISSES", &eventId)!=PAPI_OK)printf("Err2");
PAPI_add_event(EventSet,eventId);
if(PAPI_event_name_to_code((char*)"L2_CACHE_MISS:DATA:u=1", &eventId)!=PAPI_OK)printf("Err3");
PAPI_add_event(EventSet,eventId);
if(PAPI_event_name_to_code((char*)"L3_CACHE_MISSES:ANY_READ:c=3:u=1",&eventId)!=PAPI_OK)printf("Err4");
PAPI_add_event(EventSet,eventId);
However, when I read out the events with PAPI_stop, I only get 3 counts back. It doesn't seem to matter which events I specify, it's always the same result.
I've tried the same thing by using the PERF interface to Linux 3.5.4-1-ARCH. Same thing. Is this a known problem?
