    That's R600/700 class hardware

    My RV790 is working very well these days too. (Compiz, World of Warcraft, XVideo, KMS). Perhaps not "feature complete", but certainly more in the "fewer FPS" than "missing textures and random artifacts" state, which is considerably more bearable.

      That's because R600~=R700, they share the vast majority of code and they were developed in the same time
      Actually my HD3870 is already much faster with open drivers than an X1950 XTX which is the most powerful R500 card, I am probably going to buy an HD4890.

        This thing of constant chasing release cycles got already boring. Wouldn't be good idea to separate drm from the kernel completely, and distribute it like separate non-mainline kernel module. Just like the binary blobs do. That way, driver releases could be made much more frequent, and Linus will not curse us every other kernel release over *bad* code.

          linux would earn a lot to use whats best
          opensource > closed source
          commercial != closed source
          no one needs ntfs and other redmond junk

            4870/90 are extreme hot and big cards, which get pwned by evergreen easily. Go evergreen. I would, if open drivers would be more useable(to me).

              You are completely wrong in every single case. No one is going to fix YOUR bugs, opensource or not. Unless fixing that bug is a value to THEM. This way opensourcing is similar to outsourcing and freedom at same time. The code is overlooked, bug-reported and worked on nearly completely a-centric. A company that gets its driver better this way, gets more sells and as such opensourcing driver boosts company sales. In case of video drivers, they paared up with hollywood twisted DRM madness scheme - they want people to watch movie and at same time don't want people to watch movie and keep all the process a secret. And then there is linux market segment. Both problems agonise on each other and block the development.

                Uhm... maybe evergreen open source support is already mature enough. Can someone tell me how does it compare against R600/R700?

                  About the same. There are plenty of bugs, many applications that segfault or induce a kernel panic or graphics corruption, just like all the other DRM drivers.

                  Performance for reasonably simple OpenGL 2.1 and earlier games is pretty good overall. Certain games use features that absolutely slay performance (ahem, Trine, Unigine) but titles like Savage 2, Heroes of Newerth and Second Life run pretty well. But there's no shortage of bugs and regressions all the time, and stemming the tide requires active participation in the development process (e.g. reporting bugs).

                  Also mesa 7.11 and Linux 2.6.39 are the first releases that I would consider remotely useful for end-users. Prior to that major swaths of the GL 2.1 spec were either completely unimplemented for gallium, unimplemented for evergreen, or unacceptably slow / broken.

                    At least on my Evergreen (HD5670) 7.11 and a recent kernel (2.6.39) looks very good. The last GPU hangs have been fixed, everything I have tried is running there are a few minor bugs but nothing serios.

                    Saying that all drivers causes kernel panics or other bugs is simply not true and borders on the insulting, r300g for example is the most stable graphics driver I've ever used.

                    For Evergreen yes, but the rest simply isn't true. r300g is in good shape in 7.10, and Gallium3D have been supporting 2.1 for quite some time.

                      Evergreen has had some glitches until recently, but I don't remember a segfault or kernel panic on an r700 in a loooong time.

                        As of linux 2.6.38 (released at 2011-03-15), the kernel support for evergreen is on par with r600/r700, except for HDMI Audio, which is still missing for evergreen.

                        As of xf86-video-ati 6.14 (released at 2011-02-03) Xorg 2D acceleration support for evergreen is on par with r600/r700.

                        As of Mesa 7.11-git (planed to be released at 2011-07-22), 3D acceleration support for evergreen is on par with r600/r700.

                        That is not to say that there is no bugs, only that there is no more bugs for evergreen than there is for r600/r700....

                          My Evergreen HD5650 still has a rather annoying kernel freeze problem which I have been tracking for while now. I'm still collecting more data, but so far I know it has something do with fullscreen modeswitching when using OpenGL. Xrandr does not trigger the bug.

                          It doesn't happen that often, but it's annoying because it completely freezes the system. Even network goes down.

                            Does evergreen support full S3TC via libtxc_dxtn.so? Tiling? Pageflipping?

                            Thank you

                                Thank you very much, I will buy an HD5870. It's a pity that we have to wait so much for a decent support, my money will not go to amd becuase it's an old card and there is a big market for used cards. Hopefully in the future we will have a decent day one support (at least in git master).
