Farewell To The Classic R300/R600 Mesa Drivers

The death sentence to the ATI Radeon R300/R600 classic Mesa drivers has been carried out. It's all about the Gallium3D drivers now for upstream Mesa for R300 hardware and newer -- up through the latest Radeon HD 6000 series and Fusion.

What's Missing From The Mesa Drivers

Yesterday I wrote about the state of OpenGL 3.0 support in Mesa, but here's also some of the other missing items from the open-source graphics drivers.

The State Of OpenGL 3.0 Support In Mesa

Last month during XDC2011 Chicago it was publicly talked about how Intel wants OpenGL 3.0 support in Mesa and ideally before year's end. But how's that goal coming?

Mesa: Fixed Function Programs Generating GLSL

Last month at XDC2011 Chicago the long-standing goal of killing off Mesa IR was talked about by Intel. There's already been the GLSL-To-TGSI translator (and also competing with that is LunarGLASS to replace Mesa IR with LLVM IR), and now there's some new work to talk about in this area that works towards the common goal.

Getting OpenGL Transform Feedback For Gallium3D

Marek Olšák, one of the most prolific independent contributors to Mesa / Gallium3D, has more exciting work at hand. Marek has published a patch to make the necessary changes to Gallium3D so that it can implement transform feedback support, a feature of OpenGL 3.0.

Cleaning Up More Mesa Shader Code

Ian Romanick of Intel, in the conquest to deliver OpenGL 3.0 support to the open-source Mesa stack by potentially year's end, has a new patch-set for examination.

ApiTrace 2.0 Brings OpenGL 4.2, Faster Performance

Earlier this year Zack Rusin introduced ApiTrace as a new way to debug graphics drivers and other areas of the graphics stack. ApiTrace is an open-source utility that allows capturing DirectX/OpenGL API calls and to analyze them later on in a step-by-step manner. There's also other features like real-time editing of shaders and making other tweaks to how the calls are executed. ApiTrace even has a nice GUI too. Zack has now announced ApiTrace 2.0 and it makes this very useful graphics utility even much better.

Intel Has Buggy HiZ Support Published

Chad Versace of Intel has published a set of nineteen patches to the Mesa mailing list that implement HiZ and depth resolve support for the Intel Linux graphics driver. Unfortunately, it's not without some regressions.

Uniform Buffer Object Support In Mesa's OpenGL

There's patches now floating on the Mesa mailing list that provide support for OpenGL Uniform Buffer Objects (UBOs) in Mesa. This is noteworthy as it's another OpenGL 3.1+ feature that's been sadly missing from this open-source graphics stack.

Nouveau Hardware-Based Video Support In Mesa

Due to being busy with XDC2011 Chicago, there was some news missed over the weekend: there's the Mesa user-space side support for Nouveau video decoding using a hardware-based NVIDIA video decoder.

New Gallium3D G3DVL Video Patches For Merging

Emeric Grange has published a set of nine patches for the Gallium3D G3DVL video decoding stack. These patches largely originate from his work this summer on Gallium3D VP8 video decoding as part of Google's Summer of Code.

GLX_EXT_texture_from_pixmap In Software

Last week I mentioned that Chrome/Chromium OS developers at Google implemented GLX_EXT_texture_from_pixmap support for software drivers. This is the GLX extension commonly needed by Compiz and other compositing window managers. This work has been merged into Git, so is there new "desktop bling" chewing up your CPU?

After Dropping Old GPU Drivers, Ian Axes More Mesa Code

One week ago Ian Romanick called for old Mesa drivers to be removed from the mainline tree so that Mesa can move forward and be cleaned up to better the support for modern GPUs. These old Mesa drivers were DRI1-only, rarely ever received new work, and were largely for vintage graphics processors that most people haven't touched in years (e.g. the 3Dfx Voodoo days). With most developers approving this move, the old Mesa graphics drivers were removed. Ian Romanick has now moved further along with a slew of new patches to delete more code from Mesa.

A 40-Way Gallium3D Graphics Card Comparison

If you're not following me on Twitter, you're missing out on news and some very interesting photos that were posted this weekend. No, it's not of the latest beer, but of a feast of graphics cards. A 40-way comparison of NVIDIA/AMD graphics cards on Linux with the open-source Mesa/Gallium3D drivers versus their proprietary brethren is being carried out for publishing in September.
