Phoronix: More Efficient VirtIO DRM Driver To Import Scanout Buffers From Other Devices

Patches posted today by an Intel engineer allow for importing scanout buffers from other devices with the VirtIO DRM driver that is used in the virtualization space. The importing of scanout buffers from other devices/drivers can allow for more efficient use by avoiding excess copies...

This in addition to the preliminary Windows VirtualGL driver that has been added to Mesa seems like a good track.

Sadly the windows virgl from my testing has been mostly unusable for me, Im waiting for vulkan driver + zink myself.

VirGL isn't enough for Windows. OpenGL isn't a first citizen on Microsoft ecosystem. There's need of support DirectX in a (near) speed native-like way.

VirGL will support d3d10 (well, in the PR branch). d3d11 support may not be too hard to extend from d3d10, I cant say, havent looked at it but d3d11 is more or less a marginal improvement over d3d10, now "speed native like" is no where close. but for many users its still good enough.
