Compiler tuning can lead to performance improvements for many computational benchmarks by toying with the CFLAGS/CXXFLAGS, but is there much gain out of optimizing your Mesa build? Here's some benchmark results.

Mesa 9.1 should be released by the end of February as the latest version of this bi-annual open-source OpenGL implementation that continues to slowly but surely pickup new functionality for most major graphics drivers.

With all of the recent improvements going into Mesa/Gallium3D, along with some work advancements to the AMD GPU LLVM back-end, it's slowly becoming a suitable time for enthusiasts wishing to experiment with OpenCL on the open-source Linux graphics stack through Gallium3D and the "Clover" state tracker.

A bit of new code was committed this week for Gallium3D's LLVMpipe software driver that attempts to provide modest OpenGL performance as a software fallback by taking advantage of LLVM to exploit multiple CPU cores and the latest instruction set extensions on modern processors. Unfortunately, the rate of advancement for LLVMpipe still isn't too fast.

Last month I wrote about Mesa support for the ARB_texture_multisample. At the time the support was limited to enabling this OpenGL extension for the Intel Mesa DRI driver with Gallium3D and its hardware drivers going unsupported. Fortunately, the OpenGL texture multi-sample support is now heading to Gallium3D and is close to being in a good state for the AMD "R600g" driver.

With the recent improvements to MSAA Gallium3D support, if you have been wanting to benefit from anti-aliasing with the open-source Gallium3D drivers but your game/application doesn't have options to toggle the MSAA level, it's now a bit easier to configure.

Just days after fixing R300 Gallium3D HyperZ support for better performance and recently making other Radeon driver improvements, Marek Olšák is onto something new: working on Multi-Sample Anti-Aliasing improvements within Gallium3D.

While OpenGL is becoming a requirement for more of the Linux desktops out there, and ARM open-source graphics drivers aren't yet commonplace, using the Gallium3D LLVMpipe software rasterizer on ARM isn't yet a really viable solution.
