From 85ab3998c6ea28e2794a63b58cf52b634de1ddac Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 22 May 2014 17:56:33 +0200 Subject: [PATCH] drm/i915: Disable gpu reset on i965g/gm MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Ville figured out that it needs a full display reset since apparently a lot more goes down than just the GT. Until that's address it's better to just diable gpu reset.
