In this episode of The Linux Podcast, Lucas and Luna explore VFIO (Virtual Function I/O), the Linux kernel framework enabling near-native GPU passthrough to virtual machines. They break down how VFIO uses IOMMU groups to isolate devices, explain the difference between mediated and direct passthrough, and discuss real-world use cases from gaming VFIO setups to cloud GPU instances. Specific numbers: a single GPU passthrough can achieve 97% of bare-metal performance in benchmarks like Unigine Heaven. They also touch on the challenges of resetting NVIDIA consumer cards and how vendor SR-IOV support is evolving. Whether you're a sysadmin looking to optimize cloud GPU workloads or a hobbyist building a dual-boot-free gaming VM, this episode gives you the concrete mechanics behind VFIO.
