AMD rs690 initial 3D support available..

Thanks to some great work by Maciej Cencora we have initial support for 3D on the RS690 chipset. The level of support is the same as the current rs4xx chipsets, i.e. glxgears works, some other 3D apps should work, compiz doesn't work.

The changes are in the drm and Mesa master trees now and require the latest xf86-video-ati radeon DDX. I'll be getting a real rs690 post-LCA and my first task is to try and fix the r300 3D driver bugs that are stopping compiz from working, and hopefully fix a few bugs with some other 3D applications.

The RS690 is a hybrid chip with the r5xx era modesetting core combined with an r4xx 3D core with no vertex-shader/tcl support.

Specs from AMD

Do you know when AMD will release the interesting specs? All I see is about modesetting :(

rs480 - x200m

i was trying out the xf86-video-ati from git and i can say that even if it doesn't support rendered by default the driver is quite good. the only thing is that i cannot use a single opengl app. when i try to start one either it won't even start or it would hang the system and i would need a hard shutdown. i was wondering if there's some way i could help devs with resolving these issues.
ps. i seem to have got hw divx decoding on Xvideo, since my processor stays at about 10% load of the least value (800mhz) while i watch divx movies (mainly 5.2 version ones). the same movies with fglrx work at 50% load of the highest processor speed (2ghz) so this must be the hw video decoding. but i haven't find any note or other thing mentioning this feature in the driver. is it really there but is not documented or is there by chance?! i think that this feature is not one that shouldn't be mentioned in the notes, since it something that even fglrx doesn't have.

Hard shutdown very often can be avoided using "Magic keys". This is safer for your hard drive.

Re: rs480 - x200m

I don't think it is hw decoding. I think, that fglrx is in some way misconfigured, so it is eating CPU power. Do you use compiz with fglrx? That could be the problem. Fglrx+compix+xv is not good idea yet.

Re: rs480 - x200m

nope, no compiz, no overlay, and the same settings in xorg.conf. and fglrx bumps the processor load high when decoding divx5 while radeon doesn't.
this cannot be configuration issue, since it happens only with divx5 and some xvids.

Try use -vo x11 -zoom with mplayer (it forces video-output to x11 instead of xv). It is fully sotfware, but it may be faster than broken xv.

frequent freezes with older cards

it's off-topic but... i hope you know about that freeze bug with at least R100 (and maybe some newer cards):

https://bugs.launchpad.net/bugs/108527

it's affecting a whole lot of people. it was working fine in 6.6.x but is broken in 6.7.x.

XAA

Been following the xf86-driver-ati git for a while now with my r500. Phoronix published some really useful benchmarks that showed that currently, XAA is much faster (oops on my part, had been using EXA).

Everything looks really good though, and it sure is nice to have a stable system that always suspends right, resumes right, works with new kernel versions, etc, etc.

As one poster noted, xvideo would be really great, especially since it isn't even available in the binary driver (as far as I can tell). I realize the amount of work involved and the lack of current specs though.

Re: XAA

xvideo is supported by fglrx driver. Try

Option "TexturedVideo" "true"

in your xorg.conf in fglrx device section.

But it has a small problem. It renders picture into two triangles, co you can see diagonal line in specific video scenes.

Re: XAA

I've heard that the NVIDIA driver can use a single triangle that is larger than the video image and then clips it.

Re: XAA

this option could break xorg and make it lockup. if xorg fails to start with it then you might experience a very high slowdown also.
