    Phoronix: OpenCL In Gallium3D By Summer

    Zack Rusin, one of the influential developers behind the Linux graphics scene, has blogged about OpenCL support in the free software stack. Just yesterday we talked about support for OpenCL in GCC, but Zack's work deals with implementing support for the Open Computing Language into the open-source X.Org drivers. With Gallium3D, which soon will enter Mesa's mainline code-base, the OpenCL support is relatively easy to come by through just programming a new state tracker...

    That kind of statement always makes me real nervous.

        Sounds too good to be true

        But which drivers will use Gallium3D support by summer?

              ATI is a good bet, isn't there already someone working on using LLVM as an ATI shader compiler? I think that would be all the card-specific code that would be needed.

                But, will I have to upgrade my hd2600 to a newer (and expensive) card to get OpenCL?

                    Current thinking is that the open source drivers will use Gallium3D for 3xx and up. The R300 work MostAwesomeDude is doing should cover 3xx-5xx, and we plan to switch our 3D work on 6xx/7xx to Gallium3D once we have basic 3D up and running on those chips using the "classic" Mesa hw driver model.
