Plan for AMD Instinct MI50 passthrough on the Proxmox homelab host. Current constraints: the host normally runs headless with no permanent display GPU, but it has successfully booted and remained accessible headless before, which is a strong sign that reserving the MI50 for VFIO is viable. Temporary use of the gaming GPU can help during setup or recovery, but is not strictly required if headless boot remains reliable. Recommended sequence: 1) confirm BIOS settings such as SVM, IOMMU, and possibly Above 4G Decoding; 2) enable IOMMU on Proxmox via kernel params/modules/initramfs; 3) identify the MI50 PCI devices and inspect IOMMU groups; 4) bind the MI50 to vfio-pci; 5) configure a VM with q35 and OVMF/UEFI for passthrough; 6) verify the guest can see the GPU; 7) only after passthrough works, install AMD/ROCm in the guest for inference. Main likely trouble areas: IOMMU grouping, VFIO binding, AMD reset/initialization quirks, guest driver compatibility, and ROCm setup. Best first target is a Linux guest, not Windows. --- **2026-03-21 21:02:06 UTC | Created via MCP**
