PEBS sample context

Hi all,

I am using linux perf tool to monitor system-wide  (exclude_kernel == 0) PEBS samples. 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 sample (i.e., register bits)?
