Ryzen iGPU passthrough

Hi,

 

I'm trying to passthrough the my iGPU to a win10 VM.

First of all my System Information:

The GPU is in its own iommu group.

 

 

The VM works fine over VNC but when i try to passthrough the iGPU the Screen just stays black.

I've read that there are problems passing through the only gpu to a VM but with my GTX 1060 it worked fine, at that time i followed spaceinvaderones guide an put the vbios in the XML but I cant find a VBIOS for any iGPU.

Do you have any suggestions how i could get it to work?

My thought was to blacklist the iGPU in the syslinux config but I dont' know if thats a good idea?

I've also read that many people with intel CPUs just installed the right driver over vnc and then passed through the iGPU could that work and how do i do that? 

 

Thanks
