From 6161352142d5fed4cd753b32e5ccde66e705b14e Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Thu, 17 Sep 2009 16:11:28 +0200 Subject: tracing, perf: Convert the power tracer into an event tracer This patch converts the existing power tracer into an event tracer, so that power events (C states and frequency changes) can be tracked via "perf". This also removes the perl script that was used to demo the tracer; its functionality is being replaced entirely with timechart.
