Wayland Gets Flavored With Weston SPICE Back-End

The latest back-end to be published for Wayland's Weston compositor is for Red Hat's SPICE.

This new Weston back-end supports SPICE (Simple Protocol for Independent Computing Environments) remote rendering protocol as used by Red Hat Enterprise Virtualization on the desktop. There's been a lot of SPICE driver activity as of late with a QXL KMS driver and talk of a potential Gallium3D wrapper driver. This new driver though isn't out of Red Hat.

Shvedov Yury out of Moscow's State University wrote this SPICE Weston back-end as part of his course work. Right now this back-end is using the new Wayland Pixman renderer and then pushes the rendered frames over the SPICE protocol. SPICE clients can thereby connect directly to Wayland.

At the moment this back-end is targeted as a "proof of concept" and is only using shared memory buffers and there is no bandwidth optimization processes or anything along those lines. Yury does have future plans though for utilizing OpenGL for rendering and computing differences between frames.

The SPICE back-end for Weston can currently be found on GitHub.

While a different protocol, an RDP back-end was also recently merged for supporting Microsoft's Remote Desktop Protocol in a similar manner to this SPICE back-end. The RDP support was just one of many new features in Wayland/Weston 1.1.
