From 19338157c97becac1e61cc51dc0904ddfab8e9da Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 25 Jul 2013 13:31:26 +1000 Subject: [PATCH] gallium/vl: add prime support MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This fixes the dri2 opening to check if DRI_PRIME is set, and picks the correct drm device path to open, this along with a change to libvdpau allows vdpauinfo to work at least, Martin Peres tested with nouveau, and there seems to be a further issue with final displaying, it only works sometimes, but this patch is at least necessary to help debug further.
