vDPA Support in Linux Kernel

Explore the implementation of vDPA (vhost Data Path Acceleration) support in the Linux kernel in this 24-minute conference talk by Jason Wang from Red Hat. Gain insights into virtio architecture, software and hardware implementations of virtio devices, and the challenges associated with hardware virtio implementation. Delve into the concept of vDPA devices from a hardware perspective and understand the vDPA kernel framework, including its overview, bus abstraction, and drivers. Learn about the Netlink-based management API, vDPA parents, current status, and future prospects. Discover how vDPA is becoming a reality in the Linux ecosystem and its potential impact on virtualization performance.
