We'd better keep the record/report function, sometimes, we can only get

the performance issue, we always ask costumes to use "perf kvm stat -e xxx" to
append
other events, like lock:*. Then, we can get not only the information of kvm
events
by using 'perf kvm stat' but also other informations like 'perf lock' or 'perf
script'
to get the whole sequences.
Ok.
And, i think "live mode" is also useful for 'perf lock/sched', could you
implement it
in perf core?
The code will be re-usable, so lock and sched should be able to add a
live mode too.
By the way, the new version of our patchset is ready, do you want to add your
implement
after it is accepted by Arnaldo? Or are you going to post it with our patchset
together?
Then go ahead and submit it for inclusion; I'll add my stuff on top.
