Subject: Sampling instruction pointer on PPC
Date: Thu, 01 Mar 2012 18:08:10 +0100 [thread overview]
Message-ID: <4F4FACFA.6080209@bsc.es> (raw)
I am trying to sample instruction pointer along time on a Power7 system.
I know that there are accurate mechanisms to do so in Intel processors
(e.g., PEBS and Branch Trace Store).
Is it possible to do something similar in Power7? Will the samples be
accurate? I am worried that significant delays (skids) may appear.
Thank you,
Victor
