IOMMU event tracing feature enables reporting IOMMU events as they happen during boot-time and run-time. As an example, when a device is detached from host and assigned to a virtual machine, the device gets moved from host domain to vm domain.

Enabling IOMMU event tracing will provide useful information about the devices that are using IOMMU as well as as the changes that occur in device assignments. In this talk, we will discuss the IOMMU event tracing feature and how to enable and use it trace events during boot-time and run-time. The discussion will be focused on using the IOMMU tracing feature to get insight into what's happening on a system in virtualized environments as devices get assigned from host to virtual machines and vice versa. Linux kernel developers and users can learn about a feature that can aid during development, maintenance, and support of systems with IOMMU.
