From 2c88313650f3fb9f04221101901a943bb92059b2 Mon Sep 17 00:00:00 2001 From: Chuanxiao Dong Date: Fri, 13 Jan 2017 10:17:02 +0800 Subject: [PATCH] drm/i915/gvt: add more resolutions in virtual edid The current virtual edid can only support the resolution up to 1024x768. Update the virtual edid so that can support more resoltions. With this new virtual edid, resolution can be up to 1920x1200.
