DriverKit PCI for PCI passthrough to Virtual Machines

With macOS Ventura (And possibly on iOS as well) Apple is allowing the creation of PCI drivers using Driver-kit: https://developer.apple.com/documentation/pcidriverkit

From browsing over the API's and code references, it is looking like it would be possible to create a Driver-kit virtual Driver to allow a PCI pass-through of GPU's on thunderbolt connected devices (Like eGPUs).

This would allow Linux Virtual Machines to have near-NATIVE graphics performance as NVIDIA and AMD support ARM64 drivers for a lot of there cards already.

Now I personally have NEVER written a driver before, but I do know enough about them on how they work and where I could begin in writing one, but to integrate it into a virtual environment by say -- virtio, it stops there for me.

Eitherway. I think UTM has the possibility of beating VMware/Parallels to the punch, and making this possible.

Thoughts?
