I was looking for that too.
I didn't look too hard, but there was nothing obvious.
It would be very useful for example, to print all hardware counters
that are supported by the current system as you say.
To do that, I'm using this perf-hw script:
#!/bin/sh
hw_events=$(
for i in $(perf list | sed -n 's/\[Hardware.*event\]//; T; s/ OR .*//; p'); do
perf stat -e $i true >/dev/null 2>&1 &&
printf -- "-e %s \n" $i
done | tr -d '\n'
)
perf stat $hw_events $*
cheers,
Pádraig.
