GPU Passthrugh: Beelink SER8 with Ryzen 7 / 780M 8945HS

[AutomationD]

Hi all, spent 3 days nearly 24x7 with it, can't figure out what's wrong. Any advice/assistance would be highly appreciated.

Here's the github issue with mode data https://github.com/isc30/ryzen-7000-series-proxmox/issues/99

I have Beelink SER8 with Ryzen 7 / 780M 8945HS and had spent 3 days with trying to get the iGPU passthrough going. Tried so many combos and quite lost.

This is also serving as a place to collect and structure the data for myself.

Here's a rough description of what's happening:

1. Followed the guide here https://github.com/isc30/ryzen-7000-series-proxmox
2. Starting host
3. Seeing first 4 lines of the dmesg, then screen freezes
4. Created & Configured VM
5. Starting the VM - screen still has old image, VM is running but not grabbing the video

(I think video gets disconnected from the amdgpu driver and switches to vfio-pci (tests below show I can switch back to amdgpu))

Here's the current vm config

Got things working!
Got my windows VM show up on my monitor (TV in fact) and I was able to log into into it!

Still to figure out:
- [ ] AMD Reset fix (likely exe should work)
- [ ] Switching between Host/VM without a restart
- [ ] Bluetooth Device Forwarding
- [X] USB 2.0 forwarding
