This extension allows the same thing you can do with MSAA visuals, but with actual textures. Additionally it allows a tiler's pipeline to stay MSAA until the end, at which point the resolve happens to slower memory (and it's thus advantageous for that to not be multisampled).
I've had a few thoughts about how to implement it, but nothing too actionable thus far. The main issue is in conveying the desire to perform MS operations without actually supplying MS cbufs. My current thinking is to switch the "multisample" rasterizer bit to be wider and supply the # of samples to it. I'm not sure if GLES3.1 will interfere with this, since it seems to support MS textures, but something like this would be useful for freedreno and probably other tiling drivers. Thoughts appreciated. -ilia _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
