How to handle cu_ao_mask? it's invalid, yet kmd has to keep it for backward compatibility. I can't completely answer that question since I don't know the hardware background well enough. But the main questions are how it is used today and what can we do to avoid breaking existing userspace? If the value is completely ignored by user space then we can simply set it to zero and add some deprecated comment on the field. If the the incorrect value is somehow used then we should still provide it even when it is completely wrong.
