Thanks for the heads-up, Thomas. The conflict resolution seemed quite straightforward. Take a look and let me know if you think I botched anything. -Carl From ff02e7995c09278be06c34d596d3d8ca11e26ded Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom <thellst...@vmware.com> Date: Thu, 3 Jul 2014 02:07:36 -0700 Subject: [PATCH] st/xa: Don't close the drm fd on failure v2 If XA fails to initialize with pipe_loader enabled, the pipe_loader's cleanup function will close the drm file descriptor. That's pretty bad because the file descriptor will probably be the X server driver's only connection to drm. Temporarily solve this by dup()'ing the file descriptor before handing it over to the pipe loader. This fixes freedesktop.org bugzilla bug #80645. v2: Fix CC addresses.
