<pre>Hi,
with versions newer than libdrm-2.4.66 I have heavy artifacts during hw
accelerated playback of wmv files vaapi/vdpau tested with gstreamer-
0.10 and ffmpeg based mpv.
The error occures only with wmv, h264 works.
Bisect result:
db138b9ba12a0de5d6140832c0679c2418e3e7e0 is the first bad commit

radeon: Pass radeon_bo_open flags to the DRM_RADEON_GEM_CREATE ioctl
Not doing so makes it impossible for radeon_bo_open callers to set any
RADEON_GEM_* flags for the newly created BO.

If I revert this commit on the current master branch the artefacts are
gone.
