    Phoronix: German RadeonHD Hacker To Start R600 Gallium3D VDPAU

    Christian König, the independent German developer who's known for being the first to provide open-source Radeon HDMI audio support back in the RadeonHD driver days and later to KMS, last October began working on R600 Gallium3D video acceleration. He quickly brought up XvMC R600g video acceleration when porting some of the earlier XvMC R300g work. While not yet merged to mainline, XvMC on R600 Gallium3D is usable, but now he's looking towards his next target: VDPAU support for the R600 Gallium3D driver...

    "Video output of a 1920x1080 video now uses something around ~20% CPU time on my old test system, compared to ~50% with Xv, including all the nice features like overlay menu rendering for example (ok only working with mplayer right now, not xine)."
    That sounds great, and is more than I expected from XvMC. This would make most 1080p videos playable on a single core.

    Does anyone know how much work it is to enable this code? I lost track. It's in a separate branch, right?

      Is he going to work on r300g or r600g? What about ATI Avivo?

        He started on VDPAU a few weeks ago. He's not just starting now.

            He is working on r600g.

            -----------------

            I hope the xvmc code will get merged soon to master.

              afaik a state tracker is supposed to work on all G3D HW

              why is this supposed to be limited to R600??

                maybe because its only working on r600g currently? and you need some ddx changes.

                  And an state tracker does not mean all gallium drivers can use it. If an st require features that the hardware doesn't support it cant be working.

                    rejoice people....

                    ...who have a mythtv/xmbc media centre with a integrated r600g driven chip set )))))))))

                    just the news of progress will be welcome, even if it remains out of the main line mesa for a while - hopeully various major distro packers and bridge that gap.
