Topology discovery must be safe to use independently of CUDA runtime and context state. It should not initialize CUDA, require an active context, create a context, or otherwise change CUDA process state. This change restores that invariant that was previously modified in NVIDIA#167 and documents it as part of the topology-discovery API contract. It also adds GPU coverage to guard the behavior going forward.

not all hardware has a DE engine even if the driver supports it

Yes, you're right. I realized that and have been discussing this offline as well, I'll link to the existing discussion, in the meantime we should hold merging this.
