OSX_GVT-D VS i915ovmfPkg

https://github.com/vivekmiyani/OSX_GVT-D But i really dont know how to implement this? do i have to make the VM again with other settings? Or do i have to change the VM's EFI?

I currently am using a 980 Ti on my host machine, and i would like to pass the iGPU on my Ryzen 5 5600G through to my MacOS Catalina VM running in QEMU. I am running on Ubuntu 21.10. I amtrying to follow this guide, but i dont know which PCI device to pass through since there are so many. running lspci -D -nn outputs this:

While I was trying to troubleshoot the issue and reading about them on the internet I found this VBIOS for intel GPUs (https://github.com/patmagauran/i915ovmfPkg) which I proceed to use because I wasn't able to dump mine (thanks DELL for removing legacy boot).

Using the patmagauran/i915ovmfPkg VBIOS just crashes my entire system.

I came across this project and thought it was a solution to the problem. When I set the provided rom file romfile=i915ovmf.rom in the Proxmox configuration my machine hangs for a minute or two and then the host crashes completely and shuts down.

For the graphics to display output at VM start, you should research about i915ovmf.

I believe there could be some kind of "driver" like (i915ovmf)[https://github.com/patmagauran/i915ovmfPkg] but made for SeaBIOS instead of OVMF. So I would want to ask if someone knows more than me on this matter.

You need a custom vbios for Windows. MacOS will not work at all as far as I know .https://github.com/patmagauran/i915ovmfPkg

I compiled them myself using this github guide: https://github.com/patmagauran/i915ovmfPkg/wiki/Compiling

I've come across i915ovmfPkg and OSX_GVT-D but just wanted some insights if anyone has come across this issue and found a solution before I head down this path. If anyone has any ideas to help out would be greatly appreciated!
