RV770 drm failed to work

[zveanturz]

Hi everybody

I ve read so many posts about similar problem but i failed to solve my problem so i post my question. this is the post of the last hope!!!

I try to use DRi on an ati radeonHD 4850 1GB but it fail to work. If someone has got some clue to solve my problem you're welcome!

I use the last DRM from GIT
My kernel is a linux kernell 2.6.28.4
My processor is an AMD athlon X2
I use xorg-server 1.5.3 with the very last radeonHD driver ( not the official ATI driver from AMD)
I ve built the kernel with the DRI support builtin ( not as module )

here is some information

dmesg | grep drm
[ 0.377042] [drm] Initialized drm 1.1.0 20060810
[ 31.619284] drm: module is already loaded

locate libGL.so
/usr/lib/libGL.so
/usr/lib/libGL.so.1
/usr/lib/libGL.so.1.2

I ve got an error in Xorg.0.log
(WW) RADEONHD(0): Direct rendering for R600 an up forced on - This is NOT officially supported at the hardware level and may cause instability or lockups

Did you build and install the latest drm from the 6xx-7xx support branch of mesa/drm ?

It looks like you are running an old drm driver without 6xx-7xx support.

And I use mesalib 7.2 maybe i have to use mesalib from GIT.
After each attempt to solve this problem i recompile my linux kernell + drm + mesalib + libdrm.
I will ttry to use mesalib 7.3.
thanks for the clue

Yes, and you specifically need the r6xx-r7xx-support branches of mesa/drm and video-drv-ati. The master branches (e.g., "latest git") DO NOT include any of the new r7xx work. It's currently only in those branches.

Hi,

I have exactly the same error in Xorg.log, so i prefer not to open a new post.
The only difference is that i have a radeon 4670 and use Opensuse 11.1, with kernel 2.6.30. Driver is radeonhd 1.2.5.

Do you have any idea ?

I just noticed that the original poster mentioned they compiled drm into the kernel rather than as a separate module. Not sure if that is the problem, but I know all recommendations are to keep drm as a separate module *not* in the kernel, and I have seen a few people's problems go away when they rebuilt the kernel with modular drm.

bibi, can you please pastebin your xorg log and dmesg output as well ?

[agd5f]

your best bet is to use 2.6.30 as that has support for r6xx/r7xx chips included. If you built the drm into the kernel, you won't be able to load externally built drm modules.

I use a pre-compiled kernel, found in opensuse repositories, cause i have an issue with my mouse in my own .config, so i dont know if the drm is build as a modul or in the kernel.

Here is my dsmeg :

There are no drm messages at all in your dmesg output, so the kernel graphics module is either not there or not starting. You need a 2.6.30 or higher kernel built with modular drm support enabled.

I use a 2.6.30 kernel. Is this tutorial (http://wiki.x.org/wiki/radeonhd%3Ar6xx_r7xx_branch) always working ?

Thanks for the answer.
