From 57608cfd8827a74237d264a197722e2c99f72da4 Mon Sep 17 00:00:00 2001 From: Joseph Schuchart Date: Thu, 10 Jul 2014 13:50:56 +0200 Subject: [PATCH] perf script: Provide additional sample information on generic events To python scripts, including pid, tid, and cpu for which the event was recorded. At the moment, the pointer to the sample struct is passed to scripts, which seems to be of little use. The patch puts this information in dictionaries for easy access by Python scripts.
