I'm following the GVT-d guide from your Wiki at https://github.com/intel/gvt-linux/wiki/GVTd_Setup_Guide and I am having issues passing through an Intel UHD 630 device, in legacy mode to a Windows VM.

The secret sauce seems to be x-igd-opregion=on, but when I use this parameter I get a "IGD OpRegion feature: No such device" error.

If I remove the option, all I get is a black screen (while Linux guest VMs in text-mode are able to show something).

Is GVT-d in legacy mode supported on a UHD 630? If not, what's the correct way of passing through the entire iGPU to a Windows VM?

Kernel: 5.18.7-200.fc36.x86_64
CPU: Intel(R) Core(TM) i9-10900K CPU @ 3.70GHz
Motherboard: Gigabyte Z490 AORUS MASTER
Host GPU: AMD RX 6800 XT
