I had been dangling with a lot of issues with my GPU's - almost everything got sorted out. Still Hackintosh fails.
I am able to install Monterey and access it with VNC as primary GPU.
When I am passing through my HD7950 (flashed with UEFI supported rom) - I don't get any output. Troubleshooting with VirtManager VNC viewer shows this.

Enabling Logging gives me this before throwing error
I have no clue on how to read that log.
Edit : Learned how to enable debugging in OC
OCC: Missing compatible GOP - Not Found
OCC: Missing GOP on ConOut - Unsupported
OCUI: Failed to initialise output
So it seems like my GPU is not read by the OS for some reason. I had already flashed the GPU (HD7950) with a compatible UEFI rom and passed the rom via QEMU properly - so unsure why its failing. I would like to know if i can fix it by spoofing or defining the GPU ID via SSDT or the kind ? I have limited knowledge about these but i read something of the kind in whatevergreen github page.
Can someone help me resolve this?
