you just do a normal perf_event_open_syscall.
You set the attr.type field to the val
Stephane,
I think I'll start with a subset of the counters. I only need m-box at
this moment. Do you have any suggestions on where to start? Any
documents or example code?

However, I am having trouble setting up the counters.
I can access the m-box counters using perf with a command like this:
perf stat -a -e "uncore_mbox_0/inc_sel=0xa,pld=0x0500,iss=0x0/" ls
However, the even name "uncore_
