    Phoronix: 95 Patches Ready The Intel Mesa Driver For OpenGL 4 On Haswell

    Iago Toral Quiroga of Igalia has published a set of 95 patches that make the i965 Mesa DRI driver in a state for exposing OpenGL 4.0 for Haswell hardware by wiring in the ARB_gpu_shader_fp64 extension...

    Very happy about this!
    Thanks intel.

      I love this part:
      [...] accessing components Z/W in a dvec4 is still not trivial, it would require some work and probably also instruction splitting to avoid violating register region restrictions. Instead, we take advantage of a gen7 hardware decompression bug that allows us to implement Z/W swizzles without requiring instruction splitting.

        yes, but the bitter taste is, that the cpu generation is 3 years old ...

          Yes, but the newer GPUs are improvements of the same, this eventually leads to launch-day full support.

            Millions of people own 3 years old CPUs.

                I always own old PCs. I got my first PC on 1996. Since then, I haven't bought many PCs. Always use them 7 years or more so I don't like to see companies stopping support so early. I like how AMD is putting effort to support GCN 1.0 and 1.1 cards.
                My current processor is Intel Haswell. This is very good news for me!
                And like someone has said above, this is an improvement that could bring launch-day full support on future.

                  And the point is, this should all available at release and not 3 years later.

                    Well concerning graphics Intel is like AMD (ATI), they now put a lot of effort on Linux but only since a few years, so they start from far away.
                    I think that all this goes in the right way, no need to whine about the past. They fill the gap and should be thanked for that.
