Phoronix: Early Virgil 3D Results Show This Virtual GPU For QEMU Has Room For Improvement

Virgil 3D (also sometimes marked as VirGL 3D) is now part of all the key mainline components for supporting 3D acceleration on guest VMs that's then passed onto the host using a pure open-source software stack by creating a virtual 3D GPU inside QEMU. Here are some benchmark numbers...

It's promising that we're seeing any frames at all. I look forward to seeing the performance come into the useful range.

VMware seems to have the best virtual graphics driver so far. It's fairly impressive when VMware Player can support DirectX 10 games via Windows guests on Linux hosts before Wine reliably can and the 3D performance is decent--probably similar to Wine Staging + CSMT when compared to bare metal. Cannot wait to see Direct3D 11 level API support arrive in virtual drivers.

Still way better than it was. Finally looking forward to a lag free VM desktop.

I can't see the guest driver name from the test logs, maybe I just don't know where to look.

I'm 50/50 on that being llvmpipe.

Debian still didn't enable it though: https://bugs.debian.org/cgi-bin/bugr...cgi?bug=813658

Yeah, I was going to say those results line up about with what I'd expect from llvmpipe.

Still impressive that it's running successfully though.

Does anybody managed to get Ubuntu 16.04 running as guest with Virgl? I am running Qemu 2.6.0 on a Gentoo host and Ubuntu inside the VM does not come past the plymouth boot screen. Just changing the -vga option to something else fixes the boot problem, but the whole point is trying out 3D support inside Ubuntu.

He probably didn't upload the logs when it asked, but I guess it's llvmpipe because I saw better numbers from Virgil.

These tests were done on Fedora24 Beta + kraxel virgl repo - https://copr.fedorainfracloud.org/coprs/kraxel/virgl/

I'm pretty sure the numbers will be different once you pull everything from git.
