    Phoronix: Working DisplayPort Arrives For Radeon KMS

    David Airlie has announced on his blog that he and Alex Deucher have finally got support for DisplayPort-driven graphics cards and monitors working with the open-source ATI Linux driver stack. Not only is there user-space mode-setting support via the xf86-video-ati DDX driver, but the kernel mode-setting for this latest monitor interface is working too...

    Ah, the beast has been tamed. Well done, both of you!

      Cool!

      Will this also work with Evergreen, or does it use DisplayPort differently than R600/R700 ?

        I thought only



        had support for DP?

          last news was that even DVI doesn't work on Evergreen yet. Modesetting changed quite a bit due to eyefinity.

          Implementing DP on r600 is a prerequisite to implementing DP on evergreen, though.

          see here.

            I see. Thanks for clearing that out

              What proportion of users actually use DP? Reason I ask is that I've never actually seen any kind of display device that actually uses this kind of connector (although I do have one board that has a DP output... which has never been used).

              Just curious, not implying anything.

                Its a relatively new standard and I would assume it will get quite a bit of support over time since unlike DVI/HDMI, it is royalty free.

                It also has other benefits such as greater bandwidth, but these may not be of too much use on consumer laptops/desktops with average sized monitors.

                  It's just starting to become important; took longer than expected for DP displays to hit the market in volume.
