DRI troubles with radeon

[Tobias Aigner]

Hi there,

I'm having some troubles getting DRI to work. I'm runnig an
ASUS A7N8X-Deluxe Board with NForce2 and a ATI Radeon 8500. First of all
I started using the 5.2.1-RELEASE with following kernel-options:

device agp
device radeondrm

this caused XFree86 (4.3.0 and 4.4.0) to freeze on startx when DRI was
enabled. Then I removed agp and radeondrm from my kernel-config, now
dmesg showed this when startx was launched:

error: [drm:pid580:radeon_cp_init] *ERROR* radeon_cp_init called
without lock held
error: [drm:pid580:radeon_unlock] *ERROR* Process 580
using kernel context 0

but X actually started (glxinfo sayed 'direct rendering: no'). After
some reading I started to put these options in my XF86Config:

Option "ForcePCIMode" "true"
Option "AGPMode" "4"

well, ok now glxinfo reported 'direct rendering: yes' but my performance
with glxgears should be much better:

1167 frames in 5.0 seconds = 233.400 FPS
1403 frames in 5.0 seconds = 280.600 FPS

dmesg showed this:

drm0: <ATI Radeon QL R200 8500 LE> port 0xb000-0xb0ff mem
0xc2000000-0xc200ffff,0xb0000000-0xbfffffff irq 5 at device 0.0 on pci2
info: [drm] Initialized radeon 1.10.0 20020828 on minor 0 info: [drm]
Loading R200 Microcode

This problem is obviously caused by my mainboard, because my radeon used
to work with my old Gigabyte VIA mainboard.

So I'm slowly runnig out of ideas what to do.
