    Default MSAA

    Has gallium-msaa been finally merged to master? If yes, is there any reason why it hasn't still been ported to R600g?

    What about R600+ hardware?

    The article was bogus (and has now been removed). The gallium-msaa branch was merged in May 2010, not yesterday as stated.

    Yes but there is no R600g support in that commit...

    The gallium-msaa branch was just a little cleanup containing a few interface changes. It didn't add MSAA to any driver or state tracker. There is still a lot of work needed in both hardware drivers and the Mesa core. We are basically at the beginning.

    Would it be possible to add MSAA extension using MLAA (which is almost done) as a backend?

    I don't think so. MSAA is multisampling and various extensions add the possibility to read or even generate individual samples or set/get sample positions. There are no such things with MLAA.

    My RV530 on r300g supports GL_ARB_multisample. So is it supported or the extension does nothing?
