[PATCH 0/2] perf tools: Add support for PERF_RECORD_SWITCH to Intel PT
From: Adrian Hunter
Date: Thu Aug 13 2015 - 05:44:03 EST
Support to enable unprivileged users to see context switches
of their own processes has recently been added to the kernel.
These patches enhance Intel PT support to take advantage of that.
The patches apply on top of the other Intel PT perf tools patches.
