Re: User defined metrics for perf stat?

[Andreas Hollmann <hollmann@in.tum.de>]

Thanks! Now it works.

Are there any other callbacks specific to the new functionality?

I saw this:

def stat__interval(time):
   ...

The name suggests that it is called once for each interval event entry?

Anything else?

Would it make sense to extend "perf script -g" to generate the callbacks?
