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.

Mesa Threading Support Is Slow, Still Being Developed

One of the ways that Intel has been trying to make their Mesa driver faster is through proper threading support, but for now the support is unfortunately slower while the code is still being actively developed.

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.
