    Getting code to be opensourced would be hard. But they could and did, release their binaries for GPUs.

    Look at /lib/firmware/radeon. There should be plenty of files there.
    yeah thanks, I forgot about those.
    However, do you know if those binaries much work? They seem to be small compared to mesa. So rewriting those as FOSS would not have added much further delay (ignoring the fact that AMD does not want to open source those).

    The Catalyst Linux driver code-shares with the Catalyst Windows drivers, so for functionality that are common between the two OSes (eg OpenGL and much of OpenCL) we get the effect of a much larger development team. For functionality that is specific to Linux (eg X and kernel drivers) there is much less ability to share code, so progress is tied more to the size of the Catalyst Linux team than to the size of the entire cross-OS Catalyst effort.

    Another factor (possibly more significant) is that for the first few years of open source graphics driver development the focus had to be on catching up with current HW development rather than adding features to the GPUs that were fully supported at the time (R200 ). The catch-up effort is largely done now, which is why you're seeing more progress on adding features.

    but ironicaly it doesn't support ARB_buffer_storage. it is exiting times we live where open source driver surpased the closed one.
    FGLRX and Windows have AMD_Pinned_Memory as an alternative, which essentially does the same thing as ARB_buffer_storage. Although the implementation has some differences I believe.

    BTW if anybody wants to something test, try running Dolphin with this version of Mesa. It supports ARB_buffer_storage and should result in some nice speedups if its working correctly.

    EDIT: Oh and this is a different AnonymousCoward; that probably looked weird quoting myself

    That's really ironic, considering Graham Sellers from AMD was the one to spearhead this extension's development.
