Phoronix: Open-Source Radeon Driver Improvements

For those following the xf86-video-ati developments or use this open-source Radeon driver for their graphics card, you may want to check out the latest development code. Committed to its git branch today was a lot of new work from Alex Deucher, Dennis Kasprzyk, David Airlie, Egbert Eich, and Corbin Simpson. There is now bi-cubic X-Video support for the Radeon R300 and R500 series GPUs, heavy optimizations in the video functions, and lots of code cleaning...

Big improvement. I can switch virtual terminals again. Video still has some tearing, but not nearly as bad as it once was. I still cant get 3d to work.

All in all it seems to be a great improvement. Keep up the good work guys, and lets try to get 3d working again.

Mesa 7.1 also looks pretty finished to me. Release today, tomorrow? Xorg 7.4 should be released then, too, with RadeonHD 1.3 hopefully arriving in time for the october distributions.

I just updated to git master. It works just as fine as it did before, including 3D (Save for Xv tearing.)

This works fine for me too. Has anyone tried "mplayer -vo xv" (on a widescreen. I have 1680X1050) on R400 cards (I have a X800 card). Video works fine through gl2 on mplayer but the resolution gets horribly messed up when I use xv. Same behavior with the latest git driver.

On an X800 I believe radeon will expose both overlay and textured video ports, and mplayer will use the overlay port by default while the improvements are on the textured video path. Are you telling mplayer to use the texvid ports ?

I think the xvinfo command should give you details of the available Xv ports.

Are you using XAA or EXA acceleration ? Apparently EXA works much better than XAA with Textured Video.

I am using EXA.

and I used

mplayer -vo xv:\port=58 <video file>

This messes up the resolution completely. I can live with "-vo gl2" since it works fine.

xv seems to work fine on 4:3 monitor too. Looks like a widescreen issue?

Any suggestion on how to resolve this problem?

Error: couldn't get an RGB, Double-buffered visual

I get this on any 3d application I try to run? Any logs you want to see? Any configuration? Any commands you need run? Any help at all guys. I would be totally appreciative.

@duby229

Read this. I think you can also safely revert back this patch to make your 3D work again, but maybe it is already fixed in 7.1 release and you can tried that first.

Any suggestion on how to resolve this [Xv tearing] problem?

It's not possible. The only workaround is to use Gl video and enable vsync with driconf. Unfortunately this will need more CPU than Xv but it does work flawlessly (at least on my R580 chip).
