It will report n cores of each stat that you gathers w/o a way to add them up. It will also hide which CPU each stat was collected from, as it uses a global index between all stats. pmcstat needs to output CPUID, and add lines like: event: TOTAL = FR_RETIRED_X86_INSTRUCTIONS_0 + FR_RETIRED_X86_INSTRUCTIONS_1 + FR_RETIRED_X86_INSTRUCTIONS_2 + FR_RETIRED_X86_INSTRUCTIONS_3 to provide a total of the even over all cpus. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
