Thanks a lot for the feedback.

Can you send me a list of all the warnings you are seeing ? I do see
lots of warnings when running drm tests in qemu, but I am not sure if
those are caused by emulation problems or if they are expected.
A list of warnings seen on real hardware would help me prepare
additional patches to address (or, rather, suppress) those.

Thanks,
Guenter
