I was wondering whether PEBS sample can occur at interrupt context (i.e., during an interrupt is being served by the interrupt handler). If it is possible, is there any way to determine the context (e.g, process context, interrupt context) of the PEBS&nbsp;sample (i.e., register bits)?&nbsp;</P> <P>&nbsp;</P> Thu, 30 Nov 2017 20:48:39 GMT proy4 2017-11-30T20:48:39Z https://community.intel.com/t5/Software-Tuning-Performance/PEBS-sample-context/m-p/1166440#M7166 <P>Hi all,</P> <P>I am using linux perf tool to monitor <SPAN style="font-size: 13.008px;">system-wide&nbsp;</SPAN>&nbsp;(exclude_kernel == 0)&nbsp;PEBS samples.
