Hi all, I was wondering if anyone managed to activate the Kernel Modesetting on a powerpc with a radeon video card, and if yes, what are the instructions.
I have an Apple iBook G4 12" mid2005, with a ATI Radeon r300 video card
(ATI Technologies Inc M11 NV [FireGL Mobility T2e] (rev 80)), and I did
not succeed. What I tried is the following:
- add radeon.modeset=1 to the kernel options in the /etc/yaboot.conf
file and run ybin -v
- ensure that radeon module is loaded soon enough in the boot process by
adding radeon in the /etc/modules file
I am using Debian unstable, with some packages of experimental. The
relevant packages seem to be
- linux-image-2.6.32-3-powerpc kernel
- libdrm2/libdrm-radeon1 2.4.18-3
- mesa packages 7.7-4
- xserver-xorg-video-radeon 1:6.12.192-1 (built from source package in
experimental)
Everything seems to go well during the boot process, since I see in the
syslog:
[drm] radeon kernel modesetting enabled.
However, when X loads, it cannot find any dri device in the /dev/
directory, resulting in a X session without any graphic acceleration.
Typing glxinfo | grep render yields :
direct rendering: Yes
OpenGL renderer string: Software Rasterizer
In the /var/log/Xorg.0.log, I read :
(--) RADEON(0): Chipset: "ATI FireGL Mobility T2e (M11) NV (AGP)"
(ChipID = 0x4e56)

(EE) RADEON(0): [dri] RADEONDRIGetVersion failed to open the DRM

My xorg.conf file possesses only one section relative to virtual display
for a possible second screen.
Section "Screen"
Identifier "Default Screen"
Device "ATI Technologies Inc M11 NV [FireGL Mobility T2e]"
Monitor "Color LCD"
DefaultDepth 24
SubSection "Display"
Virtual 1920 1968
Modes "1024x768"
EndSubSection
EndSection
I do not know what to try next. I have KMS running on an i386 iMac with
r500 radeon card. Should I just wait for something to be fixed? Did I
miss some points in the configuration? Thanks in advance for your
precious advices.
Best,
Cédric
