    Phoronix: MSAA Anti-Aliasing For AMD Radeon Evergreen GPUs

    AMD's Radeon HD 5000 "Evergreen" graphics processors can now support multi-sample anti-aliasing (MSAA) with the open-source Radeon Linux graphics driver...

    Mesa 8.1 will arrive sooner than the 3.7 kernel right??


    Props to marek

      What is the status of MSAA on the rest of the GPUs covered by the r600g driver (R600/R700)?

      I don't know how the rest of the people that frequent this site feel, but it sure would be nice if Michael provided a bit more info on these blog posts than can already be found in the commit messages that he references.

        Performance and screenshots where?

          Note the above was not just for Michael. Anybody doing a feature that affects image quality, you must have comparison shots and benches already to submit it as working, so include links in your patch submission

            BTW is this supposed to fix the AA problems (among others) that webgl has?

              Does anybody know how to enable this for Cayman so we can test it for him?

                It will take a little longer because it's a little more complex to support on 6xx/7xx GPUs. Evergreen+ supports uncompressed AA buffers, but earlier asics only support compressed buffers. Once support for CB compression is enabled, r6xx/7xx MSAA will work. Compression support also improves performance for MSAA.

                See the r600g todo page:

                  I seem to remember that this is the last thing that r600g needs to pass the WebGL conformance tests in Firefox. Intel already passes, and I'm not sure about Nouveau (I seem to think that it does).

                  Also, according to RadeonFeature this is possibly the last feature needed for r600g to report (and actually support) OpenGL 3.0 on this hardware.

                  Also, many thanks to airlied and mareo (and everyone else contributing to Mesa) for this feature.

                    Would that help non-MSAA rendering at all?
