Re: VirtIO-GPU 3D OpenGL Hardware Acceleration for VMs and Xen

["Pasi Kärkkäinen" <pasik@iki.fi>]

Hello,

And now all the components listed below are released and available easily.

Dom0:
- Qemu 2.5 has virtio-gpu 3D/OpenGL acceleration support for VMs.

DomU:
- Linux 4.4 kernel has the virtio-gpu drm driver.
- Mesa 11.1 has the virtio-gpu 3D driver (virgl galliumd3 / OpenGL).


Did anyone try this stuff with Xen already? :)
