Hi,
I've been trying to get piglit working on radeon without X using gbm and
render-nodes, and the problem right now is that the radeon winsys is
trying to use DRM_IOCTL_GEM_OPEN, which is not allowed with render-nodes.
I'm not sure if we need to replace this ioctl with something else or
if the problem is in the gallium DRI2 implementation and we really shouldn't
be hitting this code path. Here is a stack trace:

Does anyone have any ideas what to do here?
Thanks,
