I am currently experimenting with an AMD EPYC 7302 processor on FreeBSD 12.1.
I wanted to get information about some performance counters, but apparently, there is no PMU support for this CPU:
# pmcstat -L
pmcstat: pmu features not supported on host or hwpmc not loaded
I did kldload hwpmc already.
Is there any way to get PMC counters with this CPU on FreeBSD 12.1?
