Subject: Potential BUG in drm/i915/execlists: Reset RING registers upon resume
Date: Mon, 13 Mar 2017 23:23:55 +0100 [thread overview]
Message-ID: <1489443835.5568.7.camel@mailbox.org> (raw)
[-- Attachment #1.1: Type: text/plain, Size: 662 bytes --]
I am writing regarding this kernel patch: https://git.kernel.org/pub/sc
m/linux/kernel/git/stable/stable-queue.git/tree/releases/4.9.9/drm-
i915-execlists-reset-ring-registers-upon-resume.patch .
I have identified this by bisect to be the cause of a suspend and
resume issue. Please see https://github.com/kxv/linux49.9 for the
bisect history.
After this change, a Laptop (HP Spectre x360) with Intel HD Graphics
520 will wake up from suspend to a blank screen.
Please also see this thread on the manjaro linux forum: https://forum.m
anjaro.org/t/linux-4-9-9-breaks-hibernation-4-9-8-works/17499 .
Best regards
Damian Dominik Martinez Dreyer
