[Dri-devel] DRI, MGA, kernel 2.4.9 + devfs

[Mark B. <mar...@cy...>]

====
Note:  I posted this on the dri-users list about a week or so ago
and no-one there was able to help me.  I'm still not convinced 
it's a bug, but I can't figure it out either.  Advice would be
appreciated.

Also, everything (DRI, the mga driver, etc) is built into my kernel.
====

Ok, I think I screwed something up here along the way.  I had a working
setup here but then I upgraded my glibc, and then (once that was working
for sure) my kernel.  Now it doesn't work.  Obv, something I changed 
caused the setup to break.

Relevant Data:
Kernel 2.4.9, straight.  The only patches are for LVM. devfs enabled
XFree86 4.1.0 (upgraded from 4.0.3 today trying to fix this)
glut 3.7

Ok.  So I start X, and I get this in my log:
(==) MGA(0): Write-combining range (0xea000000,0x1000000)
(--) MGA(0): 16 DWORD fifo

(II) MGA(0): direct rendering disabled


And glxinfo says: 
% glxinfo                            %(11:26PM)
display: :0.0  screen:0
direct rendering: No

And DRIsetup says:
% ./DRIsetup-linux-i386
Direct Rendering Infrastructure testing program

Checking your system.......

Your config file is /etc/X11/XF86Config
Your module path is /usr/X11R6/lib/modules
You are running in GLX Indirect Rendering Mode
The kernel module has not been loaded

(note that I build it into the kernel.  I don't load it as a module.)

dev has the files:

% ls -l /dev/misc
total 0
crw-rw-rw-   1 root     root      10, 175 Dec 31  1969 agpgart
...

% ls -l /dev/dri
total 0
crw-rw-rw-   1 root     root     226,   0 Sep  9 09:03 card0


If anyone can clue me in as to where I'm fouling this up I'd
appreciate it.  I looked through recent archives and through
some google searches but came up with nada.  

====
This is not entirely true I guess.  There were some older hits
on the devel list regarding devfs, but they were in relation to
the possibility of devfs not getting into the kernel around the 
time of 2.3.99.  Obv, it /is/ in the kernel at this point...I
assume you have support for it in dri?

Also, I pulled glxgears in case it could provide me with more
information, it dies with:
./glxgears: error in loading shared libraries: /opt/glut/lib/libglut.so.3: undefined symbol: XmuLookupStandardColormap
