GPU Para-Virtualization on Xen - Ray Huang, AMD
Last year, we introduced Virgl(OpenGL) and Venus(Vulkan) for virtio-gpu based on PVH dom0 plus HVM domU which are more complete graphic virtualization support on Xen, then we are upstreaming passthrough GPU on PVH dom0 and blob memory support for virtio-gpu on QEMU. However, Virgl/Venus is 3D driver for virtualized GPU and have higher overheads over host GL/VK APIs. To address this, we are using virtio native context approach which is leveraging RadeonSi(OpenGL) and Radv(Vulkan) for native AMDGPU in guest domU to have better graphic performance. And meanwhile, we are planning and prototyping the AMD ROCm support based on native context as well which is to provide machine learning related support like OpenCL for Xen virtualization. This solution can have both graphic and compute support with AMD GPU hardware acceleration on Xen. In this session, Ray will continue giving the introduction for this GPU Para-Virtualization solution update and future work.
