GPU Passthrough: R9 290 under High Sierra

Hey,

I recently got macOS High Sierra working on my Ryzen 1700X inside KVM and also passed through my AMD Radeon R9 290.
My host runs on Arch Linux.
I followed this guide: https://passthroughpo.st/hackintosh-kvm-guide-high-sierra-using-qemus-i440fx-chipset/

But I have one problem, macOS does not recognize my R9 290 and I already tried things like fakeID, Whatevergreen, InjectATI…
Some with no results, other with a black screen while booting.

Has anyone experience with that? Most guides refer to internal GPUs but inside KVM, there is none like an Intel iGPU.

Thanks in advance. :slight_smile:
