-
This group measures the execution port utilization in a CPU core. The group can
only be measured when HyperThreading is disabled because only then each CPU core
can program eight counters.
Please be aware that the counters PMC4-7 are broken on Intel Broadwell. They
don't increment if either user- or kernel-level filtering is applied. User-level
filtering is default in LIKWID, hence kernel-level filtering is added
automatically for PMC4-7. The returned counts can be much higher.
