Arrow Lake iGPU Passthrough

Hi can someone help me passthrough the iGPU on my 285K to an ubuntu VM? I seem to be passing it through to the VM and I see the driver loading but then when I check the console in the VM I see i915 0000:00:02.0 [drm] *ERROR} GT1: GSC proxy handler failed to init and I can't actually use the GPU in my VM

Applicable Info

• Host

  • Unraid 7.3.2

    • Plugins: I have Intel SR-IOV installed but inactive as the GPU is being passed through

  • CPU: Intel 285K

  • Motherboard: MSI z890P-WIFI (IOMMU and SR-IOV are both enabled, Primary GPU set to the iGPU with 64MB of ram assigned

• VM

  • Ubuntu 24.04.4 LTS

  • Kernel 7.0.0-28generic

  • Driver: I currently have the i915 SR-IOV driver v2026..05.06 (I've been experimenting with SR-IOV as well but thqt doesn't seem to work yet for Arrow Lake unless I'm misunderstanding)

  • Config
