GPU passthrough for retro gaming VMs requires PCI device selection, vfio-pci drivers, and compatible hardware configurations
GPU passthrough enables 3D acceleration in virtual machines by allocating physical GPU resources, but requires specific hardware and configuration steps including PCI device selection, vfio-pci driver binding, and Intel-specific vGPU support via i915-sriov-dkms for optimal compatibility.
- Configuration steps
- Use virt-manager/QEMU to add PCI Host Device, select both GPU display and audio adapters
- Driver requirement
- GPU must be bound to vfio-pci drivers; Intel requires i915-sriov-dkms module
- OS compatibility
- Works best with Batocera/Bazzite; Nvidia users may need reconfiguration
- Limitations
- AMD RX 6000 series has stability issues; single GPU systems risk host crashes
- Alternative hardware
- Intel-based systems support vGPU segmentation via i915-sriov-dkms
