Hello. I use FreeBSD 12.0-RELEASE on two machines (one with Ryzen 5 1600X processor and the other with FX-6300).
Recently (presumable after upgrading to 12.0-RELEASE) pmcstat stopped working in sample mode.
I run it as:
`pmcstat -P instructions -O test.out -n 65536 ./noisecpu` on FX-6300
`pmcstat -P ex_ret_instr -O test.out -n 65536 ./noisecpu` on Ryzen
and then I run `pmcstat -R test.out -g`
In both cases it creates directories (e.g. ex_ret_instr) which are either empty or containing only kernel.gmon
`noisecpu` is computation heavy program, calculating value noise on a large grid and works for ~8 seconds.
Conversion statistics usually looks like following:
In counting mode (with -p argument) everything seems to be working. Can anybody confirm this?
