From 05b3c681ea2f478c0cb941c2f8279919cf78de6d Mon Sep 17 00:00:00 2001

Subject: [PATCH] hw/xfree86: Propagate physical dimensions from DRM connector
Physical dimmension of display can be obtained not just by configuration or
DDC, but also directly from kernel via drmModeGetConnector(). Until now
xserver silently discarded these values even when no configuration nor EDID
were present and fallbacked to default DPI.
