Phoronix: Mesa's Virgl Preparing To Transition To Using NIR Over TGSI

Mesa's Virgl code as part of the Virgil 3D GPU project allows for OpenGL/3D acceleration within QEMU virtual machines with the driver calls then being passed onto the host GPU. Mesa's Virgl code to this stage has relied upon the Gallium3D TGSI intermediate representation while they are working on moving it to the modern and superior NIR...

Really wants to get TGSI nuked from mesa. If I recall she was not happy with vmware when they told her to wait for mid year to get their code coverted to NIR,

BTW the final virgl merge request is here: https://gitlab.freedesktop.org/mesa/...requests/13295

Is there any way to use virgl with user session Qemu/kvm VM, or it's only possible with root (non user) session? I tried enabling GPU acceleration from virt-manager in user session, and it doesn't work.

UPDATE:

OK, scrap that. I just tried it and it works! Some stuff must have been fixed big time from the last time I tested it.

OpenGL..

What about Vulkan and DirectX? What about Metal? What about a more general vGPU implementation but efficient?

that would be virtio-gpu venus which is somewhat seperate from virgl

and DirectX?

Nothing the d3d10umd could in theory be ported to virgl or zink, and then extended to dx11

What about Metal? What about a more general vGPU implementation but efficient?

again, venus. it already exists. crosvm has it and someone from collabora is working on it for qemu
