Subject: [PATCH] drm/i915: fix the issue DP-1 not working in guest
Date: Wed, 14 Jun 2017 13:47:30 +0800	[thread overview]
Message-ID: <1497419250-147816-1-git-send-email-mustamin.b.mustaffa@intel.com> (raw)

From: "Anuar, Nuhairi" <nuhairi.anuar@intel.com>

In GVT guest, when port A is DP, i915 will force it as an EDP panel,
which
will cause DP-1 not working in GVT guest.
This patch fixed this issue by check intel_vgpu_active() in
intel_ddi_compute_config().
