Subject: perf record: can I specify multiple events and use different
 sample-after value

Hi all,

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
