GPU PASS THROUGH HELP!!

[SK7]

Hello, I'm new to PROXMOX, I installed and now I want to use MAC OS and Windows 11 with GPU Pass Through, I followed almost many tutorial, But I'm failed. When I try to check after following IOMMU enable guides it still shows like this : AMD-Vi: AMD IOMMUv2 functionality not available on this system - This is not a bug.
Please help, Thanks in Advance


My PC CONFIG : Intel i9 9900K Processor
RX 580 8GB GPU

Have you setup the BIOS Correctly to enable IOMMU
https://pve.proxmox.com/wiki/PCI_Passthrough#GPU_OVMF_PCI_Passthrough_.28recommended.29
BIOS options
"IOMMU or VT-d: Set to 'Enabled' or equivalent, often 'Auto' is not the same"

I got my RX580 working with the 'romfile' Option in the above guide

Also to note you only have 1 GPU so it can only ever be attached to a single VM.
