I think I'll settle with perf record for now. Still, unlike trace

86754, 1027634 is the period value. But I'm not sure which is the PMU
value, is it just period value, or period x sample after. If so, what
is the sample after value?
You lost me. You modified perf-script to print the period?
Are you asking for the PMU counter value for 0x3c?
yes
What perf commands are you running?
perf script
(with no options)
