Hi,
I ran 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. Thanks, Devdutt. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
