From f68d697eaf3278200a7fc3c8b1d95d72837b84d8 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 4 Aug 2014 07:15:09 +0100 Subject: [PATCH] drm/i915: only hook up hpd pulse for DP outputs On HSW+, the digital encoders are shared between HDMI and DP outputs, with one encoder masquerading as both. The VBT should tell us if we need to have DP or HDMI support on a particular port, but if we don't have DP support and we enable the DP hpd pulse handler then we cause an oops. Don't hook up the DP hpd handling if we don't have a DP port. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=81856 Reported-by: Intel QA Team.
