I'm not sure yet but I don't think so.

We have a mixture of engines which can do page faults (3D, SDMA) and engines 
which can't (multimedia).

We most likely will need a way to completely separate the mapping from each 
other.

Maybe lower address range for SVM mappings and higher one for BO mappings? But 
IDK if that will be sufficient for ROCm.

Christian.
