Going over the whole thing once more I've found another design issue. How do you re-create the CPU mappings of buffers?
As far as I can see the buffers end up on a different VMA and we don't have any way of restoring that at the moment. See here as well https://www.kernel.org/doc/html/v4.15/gpu/drm-mm.html#vma-offset-manager Regards, Christian.
