      Im honestly kind of wondering if we're gonna see a bit of a 'sprint' to see how many 4.x's we can knock out before the next release...
      All opinions are my own not those of my employer if you know who they are.

        What does he even mean by "Mesa being OpenGL 4.2 compliant"? Mesa is not a driver...

          Ancurio,
          Once it's on MESA, nouveau or radeon developers can 'easily' implement it.

          Mesa matrix is looking good!
          Show Mesa progress for the OpenGL, OpenGL ES, Vulkan and OpenCL drivers implementations into an easy to read HTML page.

            OpenGL 4.3 may be the more interesting version as it marks the end of S3TC

              It is kind of sad to see r600 start to fall behind. Hopefully it will catch up.

                Mesa is a software layer that implements (among other things) the OpenGL APIs.

                  I would definitely like my Carrizo laptop to expose full OGL 4.1 when I buy it in one or two weeks.

                    Hey all. First time writer on this excellent forum. Thanks Michael for doing all this work.

                    There seems to be a potential blocker for fast ARB_gpu_shader5 support on radeonSI.
                    Does anyone knows what Dave Arlie's comment on indirect samplers on mesa git means?
                    "radeonsi: add support for indirect samplers (v2)
                    This adds the frontend support, however the llvm backend produces the wrong pattern, however we can conditionalise enabling ARB_gpu_shader5 on whatever version of llvm we fix this in."

                    is this something that won't be fixed with LLVM 3.7 and hence drag out OGL 4+ for radeonSI to 3.8?
