    Default TexturedVideo hanging with DVDs on r500

    Despite recent developments in drm and use of the CP, my machine still hangs after a few minutes when using TexturedVideo to watch DVDs. I can't really explain why it only happens with DVDs, but everything else seems to work fine.

    Does anyone know why this might happen?

    So far we've only really seen this happen with MMIO, ie not using CP & DRM. We're going to have to dig a bit deeper if you are hanging with DRM running. A few questions to get started :

    - if you play DVDs without using TexturedVideo (eg just going to x11 output) do you still get the hangs ? Any correlation with window size ?

    - any useful messages in the logs ? I have to admit I'm not quite sure where Mesa & DRM messages get logged, but hopefully somebody here is

    - are you pretty sure that DRM is being used (eg from a mesage in the X log saying that acceleration is using DRM/CP) ?

    - which app are you using to play the DVDs ?

    (II) RADEON(0): Acceleration enabled
    (==) RADEON(0): Silken mouse enabled
    (II) RADEON(0): Set up textured video
    It hangs no matter what I use to play DVDs. I've tried xine-ui, totem, and mplayer with pretty much the same result. The video stutters a lot after a few seconds, then hangs after a few minutes (although it's a little unpredictable.) The switch from mmio doesn't seem to have had any effect on my texturedvideo, (although it did make render acceleration work.)

    I'd like to try disabling DMA on my DVD drive, and see if that helps (possibly there's some kind of conflict?) but my ata driver doesn't seem to like hdparm or sdparm, so I'm not sure what to do.

    Yep, that's using DRM alright

    You mentioned stuttering after a few seconds... does the stuttering start and then continue until it hangs, or just stutter for a bit then go back to running smoothly before the hang ?

    Kind of what I probably expereince with xv and simple to HD videos on xine. I decided to stay on radeonhd though, coz with radeon my screen flickers every now and then, plus going from X to run level 3 alwyas results in a big distorted junk screen.

    IS it this bug by any chance? http://bugs.freedesktop.org/show_bug.cgi?id=15249

    Oops... what I attributed to textured video may in fact be a libata problem. As soon as I get done purging my init of the evil libata, I may be able to confirm this.

    (Sorry for the double post)

    Ack... nuking libata fixed performance issues, but intermittant kernel panics remain. On the other hand, my computer is a little screwy anyway (everything segfaults intermittantly), so it may just be a motherboard fault causing the driver to choke up. Unfortunately, I have no way to test this until I round up $400 to replace the guts of my computer (I can't exactly replace a socket 939 motherboard at this point.)
