[perfmon2] getting notified at every sample

[Dan U. <up...@vi...>]

Hi all-

I'm trying to get an interrupt every 1m instructions so that I can read some
other information in the system (such as the temperature sensor on a Core
2).  I tried building off of pebs_smpl from the libpfm4 git tree, but I
can't figure out what I would need to do to get notified every sample: if
I'm understanding it correctly, process_smpl_buffer is only called once some
buffer in memory overflows.  Is there a reasonable way using libpfm4 (or
anything from perf) to get notified at every interrupt?

Thanks,
