Phoronix: Virgl Gallium3D Inching Closer To OpenGL 4.4, Crosses Off ARB_query_buffer_object

Fresh on the Mesa 19.1 development cycle, the Virgl Gallium3D driver that is used as part of OpenGL acceleration for KVM guests with VirtIO-GPU is seeing some improvements...

Where are the Windows drivers ?

Where are the Windows drivers ?

And what's even worse no way to use it with Spice over a tcp socket

From what I read, it seems both of your complaints are related to the same problem. Virgl uses SPICE:

SPICE is based on TCP, but apparently it doesn't work on Windows.

Did anyone manage to run Linux guest on Linux host using virt-manager with Qemu/KVM + virgl in current Debian testing? It refuses to start if OpenGL is enabled. Pure Qemu runs though. Not sure if it's a libvirt issue or something else.

Is this the latest information on the interwebs for virtio-opengl-windows?

It seems Nathan "Keenuts" Gauër is still active and working on something that is IMO more important:

Spice is working well in Windows VM when using for example QXL-GPU. But no OpenGL or DirectX acceleration at all...

I also would like to know if there are some plans to do Windows driver for VirtIO-GPU with 3D acceleration capability... I guess that there was no interest in OpenGL capable Windows driver, because usage of it would be very limited...

But with Vulkan it is another story. Especially after DXVK premiere... Windows VirtIO-GPU driver with Vulkan support means almost native DirectX 10/11 support after DXVK installation!

Red Hat has someone looking at Windows drivers, just a lot of work, no timelines yet.

Thanks for your and Redhat's efforts. It's good to hear someone is working on it. Fixing the industry's compute woes sure does take priority above Windows drivers for virtualized 3D acceleration! 👍

SPICE is based on TCP

Spice works with Unix sockets as well, but when you use TCP (mandatory if the virtualization server is remote) then it won't work with virgl.
