    X2?

    Yes, I know it is not. The reason I am asking this, is because I saw gpu_address variable in some of radeon files in drm.

      I imagine the driver code needs to know about multiple GPUs even if it is only using one of them. I guess there are four stages of "support" :

      nothing at all - driver gets confused and crashes when >1 GPU

      awareness - driver can only work with one GPU at a time but knows enough to ignore the other ones

      multi-GPU - driver can support multiple GPUs with different screens on each GPU

      multi-GPU rendering - like Crossfire, driver can divide work across multiple GPU engines and combine the results to a single screen

        Well hopefully Lucid's Hydra chip makes proprietary, vender specific, multiple GPU solutions a thing of the past in the near future. (Hopefully Lucid does it to in a manner that support can be done at the kernel level.)

          Or the last round of 2009 distro releases... Fedora Rawhide supposed to get it TODAY, rawhide goes stable (if you can call it that...) as Fedora 12 on Nov 10 (if it keeps to schedule, which would be unusual).

            Btw. Does anyone know what happened to the HDMI patch that was made for the Radeon drivers ported over from RadeonHD?

            Was it applied, and end of story?

              It's not that useful even if it was since it has to be separately ported to KMS. The HDMI audio radeonhd has is strictly related to userspace modesetting and won't work with KMS without porting it altogether to KMS infrastructure.

                I see. Does that also hold for DisplayPort?

                I remember seeing Improved DisplayPort as a feature for Fedora 12. Does DisplayPort also wait for KMS to stabilize?

                  You can implement both of those both over userspace modesetting and KMS. I don't know which that feature for Fedora 12 refers to. The thing is, both need to be eventually implemented over KMS since userspace modesetting is being deprecated in favour of KMS where KMS is available.

                    So it should come on 29th of October.
                    Oops. I meant Ubuntu 10.04; I don't know what it's codename is yet.
                    Ubuntu 9.10, "Karmic", will not likely have kernel 2.6.32.

                      Ubuntu 9.10 gets 2.6.31 and Fedora 12 as well.
