    Default Update On The HD 6000 Series Open-Source Support

    Phoronix: Update On The HD 6000 Series Open-Source Support

    Yesterday afternoon AMD released the Radeon HD 6000 series open-source support for all non-Cayman GPUs. We covered the initial information regarding this kernel DRM / Mesa / DDX code drop well, but there's a few more tid-bits of information to pass along now that we have received additional feedback from AMD's John Bridgman and Alex Deucher and have also had time to look at the code patches ourself...

    Wasn't Natty supposed to ship with Linux 2.6.38?

    https://wiki.ubuntu.com/KernelTeam/S...ionAndFlavours says its likely. They have tracked 2.6.37 development so far (must be quite a large fraction of kernel rc testing).

    Thanks, good to know 2.6.38 is on the table.
    I asked cause this part of the article made me think Canonical already decided to stick with 2.6.37:

    While they won't be in the mainline tree until the Linux 2.6.38 kernel, there's a likelihood that Canonical and other distribution vendors will be back-porting this support to their Linux 2.6.37 distributions. If this is done, we may see the support in Ubuntu 11.04, etc.

    Ah that is good news for my sore eyes even if I do not own an R900 chip yet. But it is really good that the development on a stable base is now being much closer to hardware release dates. I guess also the direct use of KMS and gallium looks advanced to me. Right step into the future.

    Default 2.6.37 v. 2.6.38

    Even if Canonical does decide to stick with -37, that's what the kernel PPA is for.

    The -38 RCs are also making noise at other distributions (I found out about it on the openSuSE forums, and have -38rc2 installed in my MS5-based setup, and I would think the same is doubtless true elsewhere, especially over in Gentoo/Sabayon-land), primarily because of the increased support for KMS over and above even 2.6.37. However, throw in the kernel improvements with those late-breaking improvements in X and Mesa (most of which just missed the earlier code freezes, especially those in Mesa) makes it all the more important that they be used in tandem.

    Default Natty/Ubuntu/Other distros and 2.6.38

    Natty hasn't shipped yet; in fact, the first beta of Natty hasn't come out yet.

    2.6.38-rc2 is available from kernel.org now (and is doubtless in the Ubuntu kernel PPA already); I compiled it on openSuSE 11.4 x64 MS5 two days ago! (Two hours and sixteen minutes of compile time on a Celeron DC E1200 - but decidedly worth it.)

    Turns out there is little reason to wait, and *especially* if you have an AMD GPU of HD5xxx (if not HD6xxx) vintage; however, in order to take full advantage of that latest kernel, you also need X.org in the 7.6 series and at least 7.9 (if not 7.10) of Mesa.

    Here's why:

    OpenGL vendor string: Advanced Micro Devices, Inc.
    OpenGL renderer string: Mesa DRI R600 (CEDAR 68F9) 20090101 TCL DRI2
    OpenGL version string: 2.1 Mesa 7.10

    No proprietary anything.

    Install itself is three days old.
    Kernel is two days old.
    X install is barely two hours old.

    "have also had time to look at the code patches ourself."

    Would it be possible to link to the patches? I'm trying to wrap my head around how much code is required in each of the components (i.e. kernel, mesa, drm, etc) for this initial open source 6000 card support.

    As for Mesa (R600g/c) i see only chip indetifiers and capability. Not much. R800 and NI have indeed the same 3D programming model.

    wasn't there a vdpau/vaapi/video acceleration state tracker being developed a while back????
