HaC-Mini VS Polaris22Fixup

As kexts we need the usual suspects, but also Polaris22Fixup and maybe OldRadeonX4000HWLibs (it's inside the package). Also, I just used OC 0.7.6.

After many struggles I finally figured out how to achieve a OSX-KVM with a passed through AMD Radeon Vega RX Vega M GH discrete GPU. It apparently works with full graphics acceleration. What doesn't work yet is DRM, but should be fixable. Big thanks to osy's HacMini project, which basically solves the Hades Canyon as Hackintosh and from where I looked at and copied many things.

Next I had to define an own SSDT file for the dGPU, because changing the device-id in DeviceProperties in the config.plist wouldn't work. For this you define the device (e.g. PEGP) at the correct location (_SB.PCI0.S08) and fill in what osy did. Then compile with the iasl tool, can be done outside the VM.

The GPU is a Vega M GH (see my previous post), for which I created a custom DSDT that was inspired from the working hackintosh project at https://github.com/osy/HaC-Mini. It appears with the correct vendor and device IDs just like in the HaC-Mini project. The exercise would be to understand how to get the Vega M GH running based on how HaC-Mini, but the information is sadly unclear (e.g., where is this kext coming from?).

What should I do? I wanted to insert the device into this script so that I hope I would be able to use it as a graphics card.

for reasons I would like to make a KVM-based Hackintosh such as https://github.com/kholia/OSX-KVM and passthrough the Radeon RX Vega M GPU via vfio, which is in my Hades Canyon NUC8i7HVK. There exists a working hackintosh project for the whole PC itself at https://github.com/osy/HaC-Mini, which I used to gather more information, but I couldn't get it together into a workable state such that I run a macOS VM in KVM.

Not the question you were asking, but the NUC8i7HVK is similar form factor, with much better graphics. The HaC-Mini set-up by Osy works great (https://github.com/osy/HaC-Mini).

As kexts we need the usual suspects, but also Polaris22Fixup and maybe OldRadeonX4000HWLibs (it's inside the package).

I tried to add the dGPU to the OSX-KVM and macOS does recognize the device even as graphics adapter, but it never uses it as display device and loads no kext. I tried to remove the qemu VGA adapter (which would make the Linux VM use the dGPU when passed through) and boot into OpenCore, but I never got any display output. I tried to load the https://github.com/osy/Polaris22Fixup kext into OpenCore (just putting it in the kexts folder, I'm not sure if that is enough though).
