R300 driver on AMD64

[Jan K. <kon...@gm...>]

Hi everybody

i tried Vladimir Dergachevs R300 driver on my AMD64 Gentoo System and 
had some success. I downloaded the patches from the r300.sourceforge.net 
site and applied the drm-driver patch against kernel-2.6.9-rc2 (because 
the drm module i got from dri-cvs wouldn't work). Then i applied the 
patch for the 2d-driver against Xorg-6.8.0 (the gentoo r1 release). 
After fiddling around with the 2 rejects that where produced i compiled 
xorg and started it. Everything seems to be fine (the logs say that drm 
is enabled and dmesg reports that r300 microcode got loaded). When i 
tried the r300_demo programm it first stated unsupported card. So i 
forced it in RV350 mode and it did run. However the screenshots i made 
look a little bit different then the ones Vladimir did, but my machine 
didn't locked up ;-). I don't know if it is allowed to send attachments 
to this list, if it is i will send another email with the screenshots as 
an attachment and with my logs and dmesg output if anyone is interested. 
I could also send patches against the drm-module of 2.6.9-rc2 and the 
ati-driver of xorg-6.8.0 if they are of interest. I would also try to 
help to get this driver into a better state, however i am not an 
programmer, but i would like to test new versions of the driver on my 
amd64 system.

Lspci gives the following output for my card (to be included into 
r300_demo):
0000:01:00.0 0300: 1002:4150
0000:01:00.1 0380: 1002:4170
It is an Sapphire Radeon 9600 pro (RV350 AP).
Thanks for your work and greetings
