Description Huw Jenkins 2004-07-27 08:51:47 UTC

When using the r128  driver (snapshot from DRI - 20040726) with an ATI Rage
Mobility M3 AGP 2x graphics card on my Dell Latitude C600 laptop driving an
external SGI monitor at 1280X1024 resolution DRI is started correctly as shown
by the Xorg log:

(II) R128(0): Direct rendering enabled

However glxinfo and glxgears segfault when run. 

huw@euphoria huw $ LIBGL_DEBUG="true" /usr/X11R6/bin/glxinfo
name of display: :0.0
libGL error:
Can't open configuration file /etc/drirc: No such file or directory.
Segmentation fault

If I set the resolution to 1024X768 by adding Modes=1024x768" to the Display
section of /etc/X11/xorg.conf and restarting X glxinfo and glxgears work as
expected.

Strace shown below:

glxinfo when running at 1024x768

Comment 3 Adam Jackson 2004-07-27 10:22:53 UTC

please run glxinfo under gdb and obtain a backtrace.

type 'gdb /usr/X11R6/bin/glxinfo' at a shell prompt.  at the (gdb) prompt, type
'run', then 'bt' after the segfault.

this may be caused by, or fixed by, fxkuehl's xmlconfig.c changes, depending on
timing.  could you also try the most recent DRI snapshot?

Comment 4 Michel Dänzer 2004-07-27 11:27:49 UTC

Beware that debugging a DRI client from the same display will deadlock the X
server if execution is stopped while the client holds the hardware lock. Run gdb
from another machine, e.g. via ssh, to be safe.

gdb log of glxinfo segfault

This doesn't look very useful - not sure why debugging symbols missing...

Comment 6 Huw Jenkins 2004-07-28 02:32:00 UTC

Occurs with latest snapshot (rage128-20040727)

Comment 7 Felix Kühling 2004-07-29 03:29:03 UTC

Could you attach your configuration file /home/huw/.drirc. This would help me
reproduce the problem here if it's really related to the configuration parser.

Comment 9 Owen Taylor 2004-10-28 15:33:15 UTC

This is likely bug 1730.

Comment 10 Owen Taylor 2004-10-28 15:36:09 UTC

(I should note that the fix described in 1730 isn't going to make the card
work at higher resolutions, it should just make glxgears/glxinfo not segfault
when failing to initialize DRI)

Comment 11 Ian Romanick 2004-10-28 18:58:12 UTC

I don't know how I never noticed this bug before.  Hmm...anyway, the r128 driver
seems to have to odd quirk that it will try to enable direct-rendering even when
there is no on-card memory available for textures.  I don't think any of the
other drivers do this, but I'd have to check.  The issues that the DRI driver
assumes that there will be on-card memory but that there may or may not be AGP
memory available.

It should be fairly easy to modify the init code in the DRI driver
(r128_context.c, line 159) to not crash if r128scrn->texSize[0] == 0.  The only
tricky part is that there may be places that assume rmesa->texture_heaps[0] is
on-card memory.
