The Gallium3D compute infrastructure, which is the underlying work for supporting OpenCL over this open-source graphics driver architecture, is on approach for landing in the very near future. This has been one damn good day for open-source Linux graphics drivers following the earlier Nouveau surprise announcements.

One of the Gallium3D drivers yet not fully supporting the OpenGL 3.0 specification is the LLVMpipe software rasterizer. However, if you're curious of what's left before this CPU-based graphics driver can handle GL3, here's a list.

Besides the recent talk about using Gallium3D's LLVMpipe for Mozilla Firefox, there's another interesting technical discussion happening now about using Mesa on the web to emulate the full OpenGL API using the WebGL API.
Benoit Jacob of Mozilla is looking at the possibility of using Mesa's LLVMpipe Gallium3D driver as a means of WebGL software rendering within Firefox.

After looking at the merges that went into the major Mesa 8.0 release, Ian Romanick has called for some changes in handling the merging of feature work for future versions of Mesa.
16 February 2012 - Mesa RFC - 5 Comments
Here's another reason to celebrate today besides the release of Wayland 0.85: Mesa 8.0 has been officially released! Mesa 8.0 is what brings OpenGL 3.0 compliance to several open-source graphics drivers, advances the Gallium3D architecture, brings many new features, and a heck of a lot of other changes that materialized over the past six months.

Marek Olšák, the well-known independent contributor to Mesa that's made a great deal of enhancements to the Radeon driver stack over the past few years, has a new patch-set. The latest patch-set he published last night cleans up the R600g driver and reworks its cache flushing code. This patch-set affects more than 2,000 lines of code, which is significant for this open-source Gallium3D driver.

Marek Olšák has made another exciting commit to the Mesa mainline Git repository this weekend... What he's accomplished now is making it possible to successfully advertise OpenGL 3.0 / GLSL 1.30 support within the R600 Gallium3D driver for the Radeon HD 2000 series and later.

While Mesa/Gallium3D is still a ways off from fully supporting the Unigine Engine's advanced OpenGL 3/4 renderer with decent frame-rates, there is work both by Mesa and the Unigine Corp developers to better this open-source graphics support.

Now that Mesa is beginning to catch-up with support for newer versions of OpenGL and the OpenGL performance is slowly improving, with more games and applications beginning to work on this open-source graphics driver stack as a result, the need for application workarounds is becoming more prevalent.

There's an update to the ongoing X.Org Endless Vacation of Code work, which is currently funding a developer to work on the OpenCL upbringing within the open-source world for graphics drivers. The latest work going on has been redesigning and largely rewriting the Clover state tracker that will provide the OpenCL support to Gallium3D graphics drivers.
