  • rs690 open source support

    Hi
    I just got a new laptop with radeon x1200 (rs690).
    As much as possible I would like to avoid using fglrx but radeonhd seems to be too basic for me (for now at least as I would like to have at least basic 3d)...

    However I've noticed some commits on radeon driver git involving support for rs690 (named initial rs690 support)... So what works with that driver for the time being ? in another discussion on this forum it was mentioned that rs690 3d engine is r430 without vertex shaders and that chip is supported by radeon driver...

    so I'm a bit confused about the driver I should choose to use :P anyway for now I'm stuck with Vista as I decided to wait for kernel 2.6.24 and KDE 4.0.1

    The RS690 should work with radeon, but none of the radeon developers have had the hardware until now. I just bought a 690 board so as soon as I get it up and running I should be able to work out any remaining kinks. That should at least give you 2D accel and modesetting. 3D will take time.

      You bought a board? Can't you get it for free from ATI?

        I bought it for personal use, but I could probably expense it if I do enough work related stuff on it.

          We have AMD-designed reference boards for 690 which were used for pre-launch development and testing. We still use them sometimes but in general we're better off if the development and test work is done on production hardware instead.

            Cool ... I'll be sure to test it when it's done then (without 3d). Thanks for the answer.

              Well it works more or less now. MMIO 2D accel and output setup work fine. DDC doesn't seem to work, but I should be able to sort that out. radeonhd supports it as well.

                test it now

                Well the initial rs690 3D support due to work done by Maciej Cencora is now in the the trees, I'll get more done on it when I get my rs690 after LCA.

                  While I'm not an owner of that particular chip, and even though there's still a lot more to do, I still need to say that I appreciate all the work, time, and effort that all of you put into the development of the OSS drivers.

                  Thank you very much ^^

                      Guys thank you so much for all the work you put into this!!

                      I happen to use RS690 chip and if I could help in any way for testing or whatever you tell me I will gladly do it!!

                      Our main problem with fglrx is video support and generally 2D behaviour and performance. Also is EXA usable with the open driver?

                      I am a member of the mailing list exert said above.
                      And I think we can all help there a lot with the new stuff!!

                      Thanks again!

                      Jim

                        EXA should work but I don't know about RENDER acceleration (because on the infamous rs480 RENDER does not work and these chips are very similar) and switching to console. Do they work?

                        Edit: Looking at radeonhd.org logs it seems that VT switching still doesn't work but this issue is being worked on .

                          i don't have render on rs480. and exa has the same cursor problem that the fglrx has. with xaa adding xaanooffscreenpixmaps works but with substituting exa to xaa won't work.

                            Well I tried radeon (git 03 02 2008) from debian experimental package. 2d acceleration worked nice, however I didn't try the 3d because text console mode (ctrl alt f1) always ended up as white screen so I gave up on this driver quite fast ...

                            Now I'm running radeonhd 1.1, but any advice is welcomed should I try newer radeon or radeonhd from git ? Text console is sth that I do need ...

                              That raises a good point. We were thinking that basic 3d support would be more broadly useful than accelerating EXA Render, but for the IGP parts (where 3d is going to take a bit more work because they don't have vertex shaders) implementing full Render might make the open source drivers a lot more useful.

                              Wolke, Dave and Alex have done the hard part -- getting the 3d engine running in the 3d driver for rotation support -- so adding the blend ops for Render might be worth doing on the 3xx/4xx engine even if we didn't extend it to R5xx/6xx immediately.

                              Radeonhd from git will get you some 2d acceleration now. It needs to have CP/DRM support added to get full acceleration but depending on your CPU it might be worth moving to the latest radeonhd today.
