ok, so with this stuff something like:
perf stat -ae uncore/event=clockticks/ foo
will register a counter per cpu, which is somewhat silly since we only need one per node. What would be the best way to 'fix' this?
We could of course create another variant of -a which iterates nodes instead of cpus, -N or so.
Alternatively we could try and describe this in sysfs in some way, one possibility would be to include a link to /sys/devices/system/{cpu,node} or somesuch and use that link to iterate the correct space.
Any other suggestions?
