From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mark Brown Date: Tue, 17 Dec 2013 21:56:49 +0000 Subject: [PATCH 05/11] fbcon: queue work on power efficient wq Message-Id: <1387317415-22252-5-git-send-email-broonie@kernel.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-fbdev@vger.kernel.org From: Viresh Kumar fbcon uses workqueues and it has no real dependency of scheduling these on the cpu which scheduled them. On a idle system, it is observed that and idle cpu wakes up many times just to service this work. It would be better if we can schedule it on a cpu which the scheduler believes to be the most appropriate one. This patch replaces system_wq with system_power_efficient_wq.
