[PATCH 0/7] perf stat: Change event enable code

Show all headers | View raw

hi,
while testing ftrace:function event I noticed we create
stat counters as enabled (except for enable_on_exec couters).

This way we count also filter setup and other config code
which might be crucial for some events.

Posponing the events enable once everything is ready.

The last patch is RFC as I wasn't sure there's some hidden
catch about perf_evlist__(enable|disable)_event functions
I missed.. Adrian?

thanks,
jirka
