I'm trying use perf tool from the linux kernel package to measure several raw PMU events. In the manpage of perf-record there is an "-l" option (Scale counter values), which is useful for my case because I want to know the total counter value, not just sample count. However it seems the -l is not recognized, is this expected? How can I get a total count? Another question is that how can I specify multiple events and use different sample-after value for each of them? like perf record -c 10000,2000000,2000000 -e r2d4,r03c,r0c0 thank you
