Thunderbolt 3 GPU passthrough on linux

@wendell Would this be something you guys might be interested in researching/talking about for a video for the level1linux channel? I remembered a video you did eons ago about GPU passthrough and thought it might make for a good topic.

There seems to be very little discussion about this but is seems like it could be a really big deal. You could hypothetically pass through the entire generic thunderbolt controller same as passing through a generic USB controller, thereby eliminating the complexity of PCI GPU passthrough.

Someone on reddit's VFIO subreddit attempted it and had some limited success but never followed up about it again.

If you have the hardware on supply to try this, I think it would be a good topic. Plus it would be huge for the gaming community.

Funnily enough, your post on Twitter today about the AORUS GPU enclosure is what gave me this idea.
