Counters for L1 data cache miss on core i7

Postby nf14 » Wed Mar 24, 2010 2:41 pm

Hi,
I need to count L1 data cache misses on intel core i7. But neither L1_DCM nor L1_DCH is available on my machine. I tried to use PAPI_L1_DCA - MEM_LOAD_RETIRED:L1D_HIT. But the results look odd and really high cache misses. Is this the correct way? If not, what might be an alternative?

Thanks

Unfortunately there are various known problems with getting L1 dcache misses on i7.

Can you try the "L1D:REPL" counter and see if that gives you results close to what you expect?
