Hi,

I would like to count hardware events such as instructions retired /
unhalted-core-cycles for all the systems for BOTH OS and APPLICATION. I am
aware that pmcstat has a system wide monitoring mode that counts events
across all the CPUs for all processes. I want to know whether the
statistics for kernel code are collected as well ? (which I dont think so).

Thanks!
