Message-Id: <1280707993-6599-10-git-send-regression-fweisbec@gmail.com> Date: Mon, 2 Aug 2010 02:13:10 +0200 From: Frederic Weisbecker <fweisbec@...il.com> To: Ingo Molnar <mingo@...e.hu> Cc: LKML <linux-kernel@...r.kernel.org>, Frederic Weisbecker <fweisbec@...il.com>, Ingo Molnar <mingo@...e.hu>, Peter Zijlstra <a.p.zijlstra@...llo.nl>, Arnaldo Carvalho de Melo <acme@...hat.com>, Paul Mackerras <paulus@...ba.org>, Nikhil Rao <ncrao@...gle.com>, Tom Zanussi <tzanussi@...il.com> Subject: [PATCH 09/12] perf, sched migration: Make the GUI class client agnostic Make the perf migration GUI generic so that it can be reused for other kinds of trace painting. No more notion of CPUs or runqueue from the GUI class, it's now used as a library by the trace parser.
