Hi, i'm trying to trace the caching behaviour of one of my applications using the "perf" tool. On my i7 Q 820 i can see the l1 instruction cache loads using "perf stat -e L1-icache-loads" On my i7-2600k i'm getting "<not supported> L1-icache-loads"
Tracing the following events works fine: L1-dcache-loads L1-dcache-load-misses L1-icache-load-misses So do you know why it is possible to read dcache loads / misses and icache misses, but not icache loads? Doesn't the i7 2600k PMU provide this value or is something wrong with my kernel on this machine?
