I ran oprofile ( actually xenoprof ) with the event mask LLC_MISSES:10000. This should be L2 cache misses on Core2 arch.
After the run when I run opreport it displays :Counted L2_RQSTS events (number of L2 cache requests) with a unit mask of 0x41 (multiple flags) count 10000
LLC_MISSES:10000 | .....
My questions was whether the message is incorrect or the event mask is not being set correctly by oprofile.
My guess is that the message is incorrect but I just wanted to confirm. I am using version 0.9.3.
Another query I had was about the data on multicore archs. Does the default data comprise of the sum of cache misses on all cores ?
I have a quad core with a shared L2 cache per core-pair. Please let me know.
