FVP_RevC-AEMv8A (cache misses)

Hello,

Im using the FVP model RevC-AEMv8a, and i'm trying to verify the performance of my system with it. It is possible to verify the cache misses values?
And another question, i found it in the documentation, and can't understand this statement, can anyone explain it?

Thanks :)

Hi GGFreitas , The configuration I was using by the time was: cache_state_modelled=true cluster0.dcache-miss_latency= 127 0000

Hi,

I'm using this parameters, in order to check the PMU values (e.g. cache misses) but his value does not incremet... (my l2 cache size is 512k, and im using a 1M working set)

-C cluster0.cpi_mul=2 -C cluster0.dcache-hit_latency=100 -C cluster0.dcache-miss_latency=100 -C cluster0.l2cache-hit_latency=100 -C cluster0.l2cache-miss_latency=100 -C cluster0.l3cache-hit_latency=100 -C cluster0.l3cache-miss_latency=100
