Subject: Interrupt caused by software events

Hello,

I'm learning the perf_events programming interface and I'm not sure if
what I'm trying to do is possible. I could only find the perf_event_open
documentation, but unfortunately that's not enough for my needs, as it
only counts the number of events that happened.

I'm looking for a way to determine which instruction caused some events:
something similar to what perf annotate does, but in an online fashion. 
Ideally, I'd like to have some kind of handler that gets called whenever
a perf event occurs. Is that even possible? If not, is there any way I 
could get this information in a real-time way?

I'll be using PEBS or IBS events.

Thank you,
-Martin
