I have dell g15 5515 (RTX 3050 4GB + AMD Cezanne Radeon Vega Mobile Series, 5600H) with linux (arch btw), followed the https://github.com/kholia/OSX-KVM, and got a working setup, but purely on cpu, which is good enough, but It would be better to have a little smoothness, so thought of trying out GPU passthrough with VFIO.
I think I am paritally successful, but then what? I am stuck here.
I am using the virtual frame buffer, how do I make the GPU get used, how do I attach a display to it? virtually (or physically? if possible, but its a laptop with IGPU)
config.plist : https://pastebin.com/xm8LiPPU
slightly modified OpenCore-Boot.sh:
