Collecting raw PEBS dump on Linux

Jump to solution

Hello,

    I wish to use PEBS facility (on Westmere) to collect dump of architectural state on samples DTLB miss events. Ultimately, I wish to use the dumped architectrual state to regenerate address trace of the sampled DTLB miss events.  I was wondering if somebody can point me to the possibly best option (e.g., which tool, library) to collect this raw PEBS sample data. I should also mention that I am fairly novice on PEBS.

I am running Linux (kernel 2.6.32).

Thanks

Arka

Hi Arka, as far as I know the raw PEBS export option is not supported by Linux perf right now. But Linux kernel developers are already discussing it: https://lkml.org/lkml/2012/6/28/379 Best regards, Roman
