VFIO-Platform: Live and Let Die? - Evaluating the Future of Device Passthrough

Explore the current state and future prospects of vfio-platform in this 30-minute KVM Forum talk. Delve into the history of vfio-platform driver and QEMU integration, examining its limited upstream contributions since 2015. Learn about the steps required at both kernel and QEMU levels to enable safe passthrough of DMA-capable platform devices. Gain insights into kernel reset modules, device tree node generation in QEMU, and real-world examples of integrated and candidate devices. Understand the challenges and potential solutions for resource dependencies, helping identify devices suitable for integration. Benefit from Eric Auger's expertise as a long-time contributor to KVM/QEMU and the original developer of the VFIO-PLATFORM QEMU device and VFIO reset modules.
