Description
Xen is one of the most popular hypervisors in the world, however, the GPU virtualization on Xen is currently lacking in quite a few areas. VirtIO GPU is widely used on KVM, but less so on Xen and a number of features, including vulkan, are not currently functional in a guest VM.
To address this, we are working to have more complete graphics and multimedia support on Xen. Earlier this year, we started pushing out the first patches[1] to support venus, passthrough gpu, and virgl video on Xen + QEMU, and were invited to present it at the Xen summit [2][3] in June. We have continued improving Xen support for GPUs, adding new functionality like dGPU PRIME (Passthrough GPU rendering + VirtIO GPU display in one guest VM), and introducing virtio native context which is a more straightforward and performant way to use native drivers instead of virgl/venus in a guest VM.
This talk will provide an overview of AMDs experiences enabling GPU virtualization on Xen based platforms.
