While AMD has went months without updating their Catalyst "Legacy" Linux graphics driver for the Radeon HD 2000 through Radeon HD 4000 series graphics cards to support new X.Org Server / kernel releases and other bug-fixes, they decided today to finally put out an updated legacy driver! This updated AMD Catalyst Linux Legacy driver is tagged as version 13.1.

It's been one year since AMD introduced their Radeon HD 7000 "Southern Islands" graphics cards, but the open-source RadeonSI Gallium3D driver for providing an open-source OpenGL driver for this latest-generation of AMD GPUs is still far from being in a readied state for AMD Linux customers.

As a result of a discussion about when the AMD open-source drivers will be feature complete, AMD's John Bridgman summarized the state of some Radeon driver features like UVD video decoding, Hyper-Z, Hybrid Graphics, OpenCL, and other AMD Radeon GPU functionality on Linux.

Recently there was finally MSAA support added to the R300 Gallium3D driver. While multi-sample anti-aliasing finally made it to this open-source GPU driver that supports the old ATI R300 through R500 GPUs, benchmarks I did last week showed the R300 MSAA performance was a mess. Fortunately, Marek Olšák has made some significant performance optimizations to the R300g MSAA support.

The open-source AMD "R600g" Gallium3D driver is slowly but surely closing in on OpenGL 3.3 support for this open-source Linux graphics driver that supports from the Radeon HD 2000 through Radeon HD 6000 GPUs.

Last year UBO and TBO for the Radeon R600 Gallium3D driver was talked about and early patches proposed, but merged on Friday was finally this support for Uniform Buffer Objects and Texture Buffer Objects. With the OpenGL UBO/TBO support, the Radeon R600g driver is now advertising GLSL 1.40 as needed for OpenGL 3.1 compliance.

While the AMD Radeon "R300g" Gallium3D driver has been effectively "done" for a while, only this weekend has multi-sample anti-aliasing (MSAA) support come to this open-source graphics driver that supports the ATI Radeon X1000 (R500) GPUs and older hardware.

To be published on Thursday and Friday of this week is the annual "year in review" articles for the AMD Catalyst and NVIDIA Linux graphics drivers. While those articles are looking at the OpenGL performance for all driver releases made in the past year, some OpenCL benchmarks were also conducted.

David Airlie recently published UBO and TBO patches for Gallium3D that allowed the Softpipe driver to work with the OpenGL Uniform Buffer Object and Texture Buffer Object features. Airlie has now worked on AMD's R600 Gallium3D driver to support these OpenGL 3.x features as part of GLSL 1.40 support.

While there was already one round of driver changes for the AMD Radeon DRM kernel driver to be found in the Linux 3.8 kernel, followed by a second pull days later that landed a-synchronous DMA engine support, there's now a third set of changes targeting the Radeon driver in this next kernel release.

It was just days ago that the R300 Gallium3D driver got HyperZ support fixed-up and was finally enabled by default for bettering the OpenGL gaming performance with the open-source Linux graphics driver. Now it looks like the newer R600g driver is getting into shape for properly handling ATI/AMD HyperZ.
