Hello,

I'm using Fedora 7 and I thought I should try nouveau.  I couldn't get 
direct rendering to  work.

I found out that the Mesa package that ships with Fedora 7 doesn't 
include a DRI interface for the nouveau module. So I fetched the latest 
Mesa source from git, compiled with 'mke DRI_DIRS=nouveau linux-dri-x86' 
and copied the produced ./lib/nouveau_dri.so in the appropriate 
directory (/usr/lib/dri/nouveau_dri.so).

the driver nouveau_drv.so is provided by Fedora as well as the kernel 
module. I've added 'Load "glx"' and 'Load "dri"' in my xorg.conf, as 
well as 'Option "AIGLX" "True"'. Apart from the usual warnings from 
AIGLX for some unsupported visuals, there are no other warning or error 
messages in the Xorg.0.log

there is an error message in the kernel log though:
[drm:nouveau_mem_init] *ERROR* Unable to acquire AGP: -19

for DRI I get this:
$ grep DRI /var/log/Xorg.0.log
(II) Loading extension XFree86-DRI
(II) NOUVEAU(0): Loaded DRI module
(II) NOUVEAU(0): [dri] Found DRI library version 1.3.0 and kernel module 
version 0.0.6
(II) NOUVEAU(0): [DRI] installation complete
(II) GLX: Initialized DRI GL provider for screen 0

for DRM I get this:
$ grep -i drm /var/log/Xorg.0.log
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: open result is -1, (No such device)

drmOpenByBusid: drmGetBusid reports pci:0000:01:00.0

and for AIGLX this:
(**) Option "AIGLX" "True"
(**) AIGLX enabled
(II) AIGLX: Loaded and initialized /usr/lib/dri/nouveau_dri.so

which looks promising to me.

glxinfo reports
$ glxinfo | grep Mesa
OpenGL renderer string: Mesa DRI GeForce4 Ti 4200 Go AGP 8x 20060219 
x86/MMX/SSE2
OpenGL version string: 1.2 Mesa 7.1

unfortunately direct rendering doesn't get enabled
$ glxinfo | grep direct
direct rendering: No

Of course I know nouveau is in its infancy. Just playing with it I guess ;)

thank you for your hard work in building this driver.
