Revised Stack Space Patch For R600 Gallium3D Driver

Vadim Girlin on Sunday posted a stack space patch for the AMD R600 Gallium3D driver that he reported to improve Unigine's performance by ~30% for this open-source Radeon graphics driver. He has since revised that patch, but testing has revealed it isn't too incredibly exciting at this point.

New OpenGL Support In Mesa 9.1

Mesa 9.1 was branched yesterday, ahead of the official release next month, which effectively puts an end to new feature development on this next release. For those that haven't been keeping up with Mesa's Git activity over the past half-year, here's a look at the new OpenGL extensions supported.

Optimizing Mesa Performance With Compiler Flags

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 Release Reaffirmed For Late February

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.

Running OpenCL On The GPU With Gallium3D

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.

LLVMpipe Gallium3D Sees A Bit Of New Activity

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.

Gallium3D/R600 Support For Texture Multisample

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.

Forcing Multi-Sample Anti-Aliasing With Gallium3D

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.

Marek Takes On MSAA Gallium3D Improvements

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.

Gallium3D UBO/TBO Support Emerges - More GL 3.x

In addition to pushing OpenGL transform feedback for Gallium3D's LLVMpipe, David Airlie has released a new patch-set for Uniform Buffer Objects (UBOs) and Texture Buffer Objects (TBOs) within Mesa's Gallium3D infrastructure.

Gallium3D LLVMpipe Isn't Yet Fit For ARM

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.
