    Phoronix: Tear-Free Acceleration For ATI EXA, Xv

    For those of you that have been using the open-source xf86-video-ati driver, need we remind you of its rapidly-improving state and feature set? One of the latest additions to this open-source ATI driver that supports the old ATI R100 graphics cards up through the new Radeon HD 4800 series (RV770) is tear-free acceleration. The current implementation of this tear-free acceleration is for EXA and Textured Video (X-Video) and should eliminate any "tearing" issues that some users experience...

    will radeon merge it back?

    At least there will be some R6xx/R7xx support already at the time the documents are being released. The CS-branch of RadeonHD looks like it'll be merged to master anytime now, too (can you comment on that one, bridgman?).

    I think chances are good that this will be the one, but I don't want to sound too confident and jinx things. We've been a couple of weeks away for quite some time now

    I believe we have worked through all of those issues now and I am going to kick off another review pass this week.
    so... let's just hope.. right? or you think it will be possible that this time it will be ok?

    That's hard to predict. Depends on the issues, and whether, for example, there are things like third-party interests involved.

    Some of these things can take a long time only to find they can't be fixed, especially where there is third-party involvement. I was involved in one where negotiations went on for a year before the other side decided they didn't want to play, during which our own project was on largely on hold pending resolution.

    They offered an NDA that would have let us continue to develop pending resolution of release issues, but if we didn't get permission in the end that effort would have been lost and our devs tainted by exposure to the source so we declined and put the devs onto other projects. After awhile I got fired^h^h^h^hlaid off because without the project I didn't have a function.

    It would have been cheaper to develop an independent solution, but the lawyers kept telling us an agreement with the other was imminent. I now believe they were just stringing us along in an attempt to get us to abandon the project. It worked.
    MMh let's hope it won't be that crappy...

    Thats interesting. Thanks for working so hard on this documentation. I'm glad to see progress is still being made.
