    Default Transform Feedback, OpenGL 3.0 Ready For RadeonSI

    Phoronix: Transform Feedback, OpenGL 3.0 Ready For RadeonSI

    The AMD "RadeonSI" Gallium3D driver for Radeon HD 7000/8000 series hardware support by the open-source Linux graphics driver is about to support OpenGL 3.0. While the hardware is capable of OpenGL 4.4, the open-source RadeonSI driver has only advertised OpenGL 2.1 compliance...

    what effect would/do these patches have on performance?

    None, it's a new feature. (Unless some app tries to do this on the CPU if the extension isn't present and just uses it to speed things up, but that seems unlikely)

    So, does it just enable 3.0 or right on up to 3.1? ow much longer till the last bits of 3.2 are hammered out so that we can jump up to full 3.3 compliance? How much longer till we have OpenCL support? Can we finally have both OpenGL3.3 and OpenCL 1.* enabled by default on the spring of 2014 set of distros?

    Then and only then can we start complaining about a lack of 4.* support.

    I wasn't aware there was one, though I can't say I'm surprised - Marek and the rest of the new open source radeon developers are probably the best decisions AMD has made in a long time. While their work only affects a small fraction of customers (especially when you consider how heavily intel and nvidia outnumber ATI/AMD GPUs), they're still very productive and don't seem to show any signs of slowing down.

    3.1 requires UBOs and TBOs
    3.2 requires geometry shaders
    3.3 is pretty much done once 3.2 is finished
