This is a note to let you know that I have just added a patch titled drm: Stop resetting connector state to unknown to the linux-3.19.y-queue branch of the 3.19.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.19.y-queue This patch is scheduled to be released in version 3.19.8-ckt6. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.19.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 896f4e799d4dd00534a7ca6f00464312ba33ff4b Mon Sep 17 00:00:00 2001 From: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu, 16 Jul 2015 16:47:50 +0200 Subject: drm: Stop resetting connector state to unknown MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit 5677d67ae3949f09f57357241b88222d49b8c782 upstream. It's causing piles of issues since we've stopped forcing full detect cycles in the sysfs interfaces with commit c484f02d0f02fbbfc6decc945a69aae011041a27 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Mar 6 12:36:42 2015 +0000 drm: Lighten sysfs connector 'status' The original justification for this was that the hpd handlers could use the unknown state as a hint to force a full detection. But current i915 code isn't doing that any more, and no one else really uses reset on resume. So instead just keep the old state around.
