RadeonSI Gallium3D Receives MSAA Support
Written by Michael Larabel in AMD on 9 August 2013 at 12:01 AM EDT. 4 Comments
Marek Olšák, the well known Radeon Gallium3D contributor and AMD's newest open-source employee, has implemented multi-sample anti-aliasing (MSAA) support for the "RadeonSI" Gallium3D driver plus made other changes.

MSAA is needed for GL3 compliance and is generally expected of modern GPU drivers in 2013. The R600 Gallium3D driver has had MSAA support for a while now and finally it's come to RadeonSI, the Gallium3D driver for AMD Radeon HD 7000/8000 series graphics cards.

A set of 20 patches posted this week by Marek implement MSAA rendering, texturing, and color-buffer compression. Still to be done though is MSAA fast color clear support and on top of the 20 patches there are also some LLVM shader back-end changes needed too. While some of the code was ported from R600g, the RadeonSI patches are implemented for maximum hardware performance.

The current patch-set, which has yet to be committed to Mesa Git for Mesa 9.3/10.0, can be found on the Mesa mailing list.
