Description

Is your feature request related to a problem? Please describe.
Related to #1788 but different. I'd like to pass through my AMD GPU in its entirety to the guest VM for ROCm workloads. The solution described only works on CUDA but not anyplace else.

Describe the solution you'd like
I'd like DDA/PCI passthrough for WSL2, this will allow any device to be passed through. Even if it doesn't stay connected to the host, this is exactly the behaviour I want. Since WSL2 is based on Hyper-V, and HyperV has passthrough support, and it's even present in Windows 10 not just Windows server according to some reports, this should be doable as a feature.

Describe alternatives you've considered
Passing through just ROCm won't work as there's no ROCm for Windows 10. In addition, I'd like nested virtualization (Docker/KVM) on the guest.

Research direction

Start with the related issue #1788 and the linked Hyper-V DDA documentation to understand the existing CUDA-only approach and the requested PCI passthrough behavior. Done means WSL2 can pass through an AMD GPU or other device to the guest, while supporting the requested nested virtualization use cases.
