We have known that Gallium3D
would soon be landing in Mesa
and now it looks like that will take place this week. In fact, Gallium3D is in the process of being merged to the master development branch right now and should be complete within a day or two. Gallium3D will then appear in Mesa 7.5 / 7.6, but not the forthcoming stable Mesa 7.4 release.
Building the Gallium3D support and drivers in Mesa will not be done by default at this time, but will require a special build argument. If you are unfamiliar with Tungsten's Gallium3D architecture for writing new graphics drivers on Linux and other operating systems, check out our other Gallium3D articles
or the Tungsten Graphics Wiki
The announcement of the merger this week was made on the Mesa3D mailing list
