  • Eyefinity on open source drivers?

    I was just looking at Anandtech (http://www.anandtech.com/video/showdoc.aspx?i=3635) about the new multi-monitor features in the next generation cards. Apart from the nerdgasm over making an übergeek desktop out of this, this part about Single Large Surface caught my eye:

    "AMD's software makes the displays appear as one. This will work in Vista, Windows 7 as well as Linux."

    Since the cat is officially out of the bag on this now, you can see the screenshot from Catalyst but is this feature coming to the open source drivers too?

    No promises, but we believe this will be fairly easy to support in the open source drivers.

      To feed your tech-envy the 24 monitor setup below was under Linux.

      4-GPU 1 head per GPU, with RANDR based bezel correction. All on a single machine. X-Plane was the sim. Each 3x2 quadrant was 6500x2500 (ish).

      We can switch on Xinerama, but some of the quirks with Xinerama burn through memory unbelievably fast when you have 13000x5000 as a single display.

        Wow- that looks amazing- congrats to AMD for an awesome achievement here.

          Cool concept but I've never liked having the bezel grid. I'd never play a game like that.

            Got Docs?

            Sweet.

            Now we just need AMD to hurry up and release the r800 documentation!

              Well, first we need to *write* the documentation

                  Write the driver before, then write and release the doc.

                  Otherwise, about the 13000x5000 resolution: it strikes me that we're approaching various 16-bits limits in X11 fast. I wonder what'll be the way forward to overcome them ?

                    overwrite every 16 with a 32 and hope for the best

                      It looks like there are three pillars of "eyefinity" that need to be combined for the monitor wall seen in the videos.
                      1. Fast GPUs
                      2. enough outputs on each card
                      3. A method to spread the drawing over multiple GPUs
                      My understanding is that 3. (and any kind of multi-GPU-on-single-X-server support) is a huge TODO item that can't be picked up until kernel memory management is done and may not be started until after the G3D transition.

                      bridgman, when you said it's probably easy to support in OS drivers, did you refer to points 1. and 2., or did you include point 3.?


                      granted, there has been quake 3 on 24 monitors back in 2006, and maybe DMX will work again soon.. is that the OS solution you have in mind?

                        I was just talking about point 2 - enabling >2 outputs on a single card.

                        Point 1 will happen over time anyways.

                        Point 3 is only implemented by proprietary drivers today AFAIK (we call it Multiview) and is a bunch of software work, but it's pretty much independent of the hardware.
