Description Laurens Vets 2005-09-17 21:55:40 UTC

I'm trying to get drm working on an alpha personal workstation 500a.  I pulled
Xorg, Mesa and drm sources from CVS on September 14th.  Build everything by
following this guide: http://dri.freedesktop.org/wiki/Building, but drm did not
work.  When I start X, I get the following errors in my Xorg.log file:

Has anyone else seen this kind of behaviour?

Comment 1 Dave Airlie 2005-09-18 02:31:51 UTC

Okay I've fixed the DRM to not use pci_find_class on alpha as per what is in the
mainline kernel.

Comment 2 Laurens Vets 2005-09-18 02:57:33 UTC

Thanks ;) Is this in CVS so I can test this?

Comment 3 Dave Airlie 2005-09-18 18:16:37 UTC

nope I'm taking the whole DRM closed source and not releasing any more changes :-P

or else this change might be it.
http://cvs.freedesktop.org/dri/drm/linux-core/drm_fops.c?r1=1.37&r2=1.38

I'll close this bug refile if there is another bug as this is just a problem
with DRM on Alpha full stop.
