The Many Faces of Virtio-GPU: Capabilities, Implementation, and Use Cases

Explore the versatility of virtio-gpu in this 29-minute KVM Forum talk by Sergio Lopez Pascual. Delve into the device's role as a paravirtualized GPU and display controller, examining its three main primitives: virtqueue transport, shared memory, and fences. Discover how these elements enable multiple specialized personalities to support various use cases, from native DRM to GL abstraction and GPU compute offloading. Learn about current and future virtio-gpu capabilities, their implementation, and intended applications across different software stacks. Gain insights into leveraging these features effectively, with a possible demonstration of a lesser-known capability. Access accompanying slides for a comprehensive understanding of this powerful virtualization component.
