Explore the integration of IOMMUFD in QEMU through this informative conference talk. Delve into the new user API for controlling the IOMMU subsystem, designed to replace IOMMU-related user APIs in VFIO and centralize new IOMMU features across userspace driver frameworks. Understand the necessary redesign of QEMU to adapt to the new IOMMUFD uAPI while maintaining backward compatibility with legacy VFIO uAPI. Learn about the abstraction methods used to accommodate both device-centric and group-centric models. Examine the gaps in IOMMUFD adoption and backward support for QEMU, and discover how the two types of IOMMU user APIs can coexist. Gain insights into the impact on management layers like libvirt and explore new features such as IOMMU nested translation.
