Hello everybody,
I have solved my performances problem with the help of "the wner" thanks to him. Here is the full report. I hope this can help some guys there.
1 - The history:
----------------
I had a Excalibur Radeon 9500 pro and I was using sucessfully the fglrx drivers (based on flavio work). It was running both in 64 bit and 32 bit.
I decided to use a Radeon 9250 for two reasons: - it has free drivers - it is fanless (passive heatsink) so noiseless So I bought an Asustek A9250T/D.
To ease the change, I used first the fglrx drivers. I had nothing to change to the system and I got 920fps in glxgears (windowed) with XFree86 4.3.0. Only tuxracer was not working giving me a corrupted screen.
Then I decided to switch to the "radeon" driver.
I removed the fglrx driver packages and changed my XF86Config-4 file to reflect the changes.
2 - The problems: ----------------- As related before I got 2 problems: The fps was low: 450fps and glxinfo reported that dri was not in use [... ] name of display: :0.0 display: :0 screen: 0 direct rendering: No [...] And some strange things: [...] client glx vendor string: SGI client glx version string: 1.2 [...] OpenGL renderer string: Mesa GLX Indirect
In the same time, XFree86.0.log reported the dri wan enabled: (II) RADEON(0): [drm] register handle = 0xfbe00000 (II) RADEON(0): [dri] Visual configs initialized (II) RADEON(0): [DRI] installation complete
If I tried to restart gdm I got a machine exception as reported before.
3 - the solution:
-----------------
"the owner" (thanks to him) pointed me to the possible use of the fglrx libs instead of the xfree ones.
I double checked.
Removing the fglrx packages removed the diversion of LibGL but didnt restore the symlinks.
After the reinstallation of xlibmesa-gl, the problem got fixed:
glxinfo reports:
direct rendering: Yes
[ ... ]
client glx vendor string: ATI
client glx version string: 1.3
[ ... ]
OpenGL vendor string: Tungsten Graphics, Inc.
OpenGL renderer string: Mesa DRI R200 20020827 AGP 4x x86/MMX/3DNow!/
SSE TCL
OpenGL version string: 1.2 Mesa 4.0.4
4 - configuration: ------------------ I've hardcoded in the kernel agpgart, amd64_agp and radeon. My XF86Config-4 is attached.
5 caveat: --------- I have set explicitely AGPFastWrite to off. Option "AGPFastWrite" "off"
If it is set to on I've the Machine Check reported before.
Regards
Jean-Luc
I've the same if I don preload amd64_agp, agmgart and radeon modules in this order with the free drivers.
And BTW, glxinfo reports direnct rendering=No. glgars repors 450fps while I get 920fps with fglrx drivers. with fglrx, the radeon driver shouldnt be loaded.
When the screen is black, I've a beep after a while and a machine check in the logs.
tangerine-64 kernel: agpgart: Putting AGP V3 device at 0000:01:00.0 into 8x mode tangerine-64 kernel: CPU 0: Machine Check Exception: 0000000000000004 tangerine-64 kernel: Bank 4: b200000000070f0f tangerine-64 kernel: Kernel panic - not syncing: CPU context corrupt
I manage in this casre to use the magic keys to do an Emergy sync
[Altgr-Syst request-S], umount R/O [Altgr-Syst request-U] ans emergency rebbot [Altgr-Syst request-B]
I've the same behaviour with both 64 bit and 32 bit system.
I've remarked the same machine check with a Radeon 9200SE on a friend machine.
My card is an Asus A9250T/D and I sue only the analog output.
I've never the machine check with the fglrx drivers.
