DRM not working with 2.6.11.5

DRM not working with 2.6.11.5

[ross]

Hello everyone,

I recently upgraded to 2.6.11.5 (back when it came out) from 2.4.
One of the reasons I upgraded was to get DRM working with my computer
again.

The AGP and DRM modules load fine, but when xdm starts, I have no
direct rendering.

The machine is an ASUS A7V8x-x with VIA chipset KT400.  The video card
is a Matrox G400 DualHead.  I've had the exact same video card working
with different motherboards.


Here is the only DRM output relevant to AGP/DRM:

Linux agpgart interface v0.100 (c) Dave Jones
[drm] Initialized drm 1.0.0 20040925
[drm:drm_fill_in_dev] *ERROR* Cannot initialize the agpgart module.
DRM: Fill_in_dev failed.

Thanks very much for any tips!

You didn't load the agp chipset module..
it would be nice if it happened automatically...

Dave.

Spot on - thanks man.  Will update rc scripts from 2.4.  Thanks!

Adam Jackson was looking into this a few days ago by making
the generic agpgart.o send hotplug events to trigger a load
of the submodules. If he comes up with something I'll throw
it at -mm if it looks sane.

is that needed? If the agp submodules advertise a list of pci id's isn't
that enough to get them auto loaded ?

(that works for all other modules in the kernel... ;)
