In the user guide the description of "2nd-level Cache Read Misses", it shows the defination.
The number of 2nd-level cache read misses as seen by the bus queue for memory load misses and RFO misses.
What does "seen by the bus queue" mean?
I have a problem to solve here. I am trying to collect all the 2nd-level cache misses except all the misses caused by hardware prefetches. How can I do that? I think the "2nd-level Cache Load Misses Retired" include the misses caused by hardware prefetch, right? What about "2nd-level Cache Read Misses"?
