Hi,

I've seen, there's a drm module in the source code.
I use an ATI Mobility X600 PCIe chip in my notebook. I've loaded the 
radeon.ko module and have an empty directory /dev/dri, but the 
Xorg.0.log tells me:
[..]
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (Device not configured)
drmOpenDevice: open result is -1, (Device not configured)
drmOpenDevice: Open failed
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (Device not configured)
drmOpenDevice: open result is -1, (Device not configured)
drmOpenDevice: Open failed
[drm] failed to load kernel module "radeon"
(II) RADEON(0): [drm] drmOpen failed
(EE) RADEON(0): [dri] DRIScreenInit failed.  Disabling DRI.
[..]

Can somebody please point me to a documentation about setting up 
DRM/DRI or give me some hints?

Thanks,
Thomas
 

Hi there Thomas ---

   Sorry, but to my understanding, anything ATI newer than Radeon 9200 
series (Rv280) does not have the native kernel level support for DRI/DRM 
under Xorg running on any BSD or linux.
There are proprietary (binary) drivers for Linux available from ATI 
which possibly support DRI or video acceleration features, but these 
drivers are generally reported/regarded as poor in quality and may be 
unstable under some linux distributions. YMMV.
Perhaps we should urge AMD (when they complete the takeover of ATI) to 
open the documentation to linux and BSD developers.
Sorry to revive such an old topic, but your understanding is incorrect. 
 There are open source 3D drivers for everything up to, and including, 
the Radeon X850 in the Mesa source tree (and Xorg 7.1, possibly 
earlier).  Anything newer than the Radeon 9250 is still considered 
relatively experimental, but it is certainly functional enough of linux 
and FreeBSD to play a couple rounds of doom3 or quake4.

My guess is that there just hasn't been a recent update to the radeon 
drm code in DragonFly.
