Description Manuel Pancorbo 2005-07-24 21:06:34 UTC
Dell 4550, ATI-Rage card and "r128" driver. Xorg installed from Debian unstable.
DRM-modules installed from fresh snapshots at
http://dri.freedesktop.org/snapshots/ : 

Installation was ok. Further X-launch reported no problem:
(II) R128(0): [drm] created "r128" driver at busid "pci:0000:01:00.0"
(II) R128(0): [dri] Visual configs initialized

But 'glxinfo' yielded following:

libGL warning: 3D driver claims to not support visual 0x24
libGL warning: 3D driver claims to not support visual 0x28
libGL warning: 3D driver claims to not support visual 0x2c
libGL warning: 3D driver claims to not support visual 0x30
Violación de segmento

(so, "segmentation fault")
My .drirc is simple <driconf></driconf>

The output of 'gdb /usr/X11R6/bin/glxinfo' after 'run' and 'bt' is:

Please attach (as opposed to paste) the full X server log and configuration files.

Comment 4 Manuel Pancorbo 2005-07-25 20:55:22 UTC
I've just seen a warning when inserting "r128":
PCI: Unable to reserve mem region #1:4000000@f8000000 for device 0000:01:00.0

This seems uncritical warning, because the module keeps inserted and the whole
X-system works ok with no error at launch time. But perhaps this concerns the
reported bug on DRM-system.
Comment 5 Eric Anholt 2005-08-05 14:56:04 UTC
(II) R128(0): Reserved 0 kb for textures at offset 0xfff000

That sure looks like the problem to me.

Comment 7 Matt Turner 2010-12-02 13:02:21 UTC
Is this still a problem?
Comment 8 Ian Romanick 2015-11-30 23:43:09 UTC
The r128 driver longer exists in Mesa.
