GPU passthrough not working

[GetToVeryMy]

CPU: ryzen 7 7700
Because virtualized screen is crap, i decided to forward my igpu to VM. But mac os doesn't see it. Black screen on monitor, which is connected to igpu. I tried to dump vbios and specify it in romfile - didn't help.

Hi @GetToVeryMy! I'm Dosu and I’m helping the OneClick-macOS-Simple-KVM team.

The OneClick-macOS-Simple-KVM project does not include built-in support or documentation for GPU passthrough (VFIO/PCI passthrough) or for Ryzen CPUs. The scripts and templates default to virtualized graphics (like QXL) and do not contain the or vfio-pci device entries needed for PCIe passthrough. There are also no AMD- or Ryzen-specific accommodations or optimizations in the codebase, and the design assumes emulated Intel CPUs for macOS compatibility, which may further complicate passthrough on Ryzen systems template.xml.in.

For your setup, common issues include: IOMMU not enabled in BIOS, ACS patch not applied (if needed for proper device isolation), or missing vfio-pci binding for your iGPU. macOS is also very particular about GPU hardware and often only works with specific models (typically certain AMD dGPUs); iGPU passthrough, especially from AMD platforms, is rarely reported to work with macOS.

You would need to manually edit your QEMU/libvirt configuration to add a entry for your iGPU, ensure vfio-pci is binding to the device, and possibly spoof device IDs or use custom SSDTs/kexts for macOS compatibility. Since the repository does not provide examples or scripts for this, you will need to rely on general QEMU/KVM passthrough guides for Linux and Hackintosh/macOS forums for device compatibility tips.

If you need further help, searching for "macOS KVM GPU passthrough Ryzen" in community forums may yield more targeted advice, as this project does not cover your use case.

To reply, just mention my name @dosu.
