From ee6f280e7895c838d90e8ef19ba737c8003ae85d Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Thu, 23 Oct 2014 19:23:22 +0300 Subject: [PATCH] drm/i915: enable output polling during S4 thaw MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit To avoid processing hotplug events we disable connector polling for the duration of S3 suspend. We also disable it for S4 freeze, and keep it disabled after S4 thaw. This won't prevent though hotplug processing, since we re-enable interrupts anyway. There is also no need to prevent it at that time, since we reinitialize everything during thaw, so the device is in a consistent state. So to simplify things enable polling during thaw, which will allow us to handle S4 thaw the same way as S3 resume in an upcoming patch.
