DRI on an iBook2

DRI on an iBook2

Hi,
I see on the DRI project (http://dri.sourceforge.net/) page that the
ATI Rage128 Mobility chipset is supported by XFree86 DRI.  However,
I'm not having a whole lot of luck getting anything working on my
iBook2.  I notice that I *can* turn on the kernel option for the DRM
and select support for the ATI Rage128.  My question to this list
before I spend too much time beating my head against this is whether
or not DRM and/or DRI for the ATI chipsets are supported on LinuxPPC.

Thanks...
Ethan

Hi,

On PPC, we can't use AGP GART because of the lack of documentation for
the chipsets Apple uses on its motherboards. But we have PCI GART.

Grab the DRM modules sources here: http://xfree86.org/~alanh/

Compile, insmod r128.o, modify your XF86Config to include the dri,
glcore and glx modules, and use 16bpp by default (the iBook2 doesn't
have enough video ram to do OpenGL at 1024x768@24bpp).

Start X-Windows and you should be set ;)

glxinfo's first lines will tell you if you got DRI to work.

Cheers

PS: If you want to see my XF86Config-4, tell me, I'll post it on my site.

Hmm,

I forgot to ask. Does anyone know when the DRM drivers would be updated
in the main kernel tree ? Ben, would you include that in your tree ?
(given that what's in right now is useless on any PPC/Pmac machines anyway)

Cheers

They will either be updated or removed entirely in the end. There has been a
lot of discussion about compatibility and other technical problems on
dri-devel and lkml.
