Hi all.

I'm really frustrated by now. I've been trying to get 3d support on my HP Pavillion (with the "famous" Radeon IGP Chip) for days now. I'm running Slack10 on the 2.4.26 kernel. The Kernel was recompiled several times and the /dev/agpgart and drm sectins seem correct.

I think that i got the X-server running. /var/log/Xorg.0.log looks good. As well as /etc/X11/xorg.conf.

BUT: my agpgart module doesn't work, /var/log/dmesg:

...
Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 380M
agpgart: Unsupported ATI chipset (device id: cbb2), you might want to try agp_try_unsupported=1.
agpgart: no supported devices found.
...

modprobe agpgart:
/lib/modules/2.4.26/kernel/drivers/char/agp/agpgart.o: init_module: No such device
/lib/modules/2.4.26/kernel/drivers/char/agp/agpgart.o: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg

lspci -v sais:

Any ideas what i can do? Thanks for any help.

Here is a link to a work around in adding kernel AGP support for a chipset , I haven't tried it myself so I can't really say how good it works.

LinuxElectrons

thanks, but this link provides info for the wrong chipset.

found a solution:

The Agpgart module works fine with the 2.6.7 Kernel -> so i finally got 3d support!! :-)

But: i didn't manage to get my HSF Modem (Conexant) working on that Kernel, it only works with the 2.4.x Kernel. Or is anybody using it with the 2.6.x??

I seem to have been in the same quandry as you, D, assuming you had some 8x agp bus problems. However, your 2.6.7 kernel works fine, and mine does not. It might be that I am still using Slack 9.1, but i am doubtful. I can compile the kernel and do the make modules, and make modules_install, but when I boot the new kernel I do a lsmod to only find that no modules are running. Did you do anything special?

By the way, with your HSF modem (I'm not really sure what that means!) make sure you are very thorough when configuring your kernel with xconfig or something, and recompile. You might need to check something like PPP support which is normally disabled.

@BiggMike

A HSF modem is a "software-" or "lin-modem" with a chipset by Conexant. In my case I simply assume, that the drivers don't work together with the 2.6.7 kernel.

Agpgart: No, I didn't do anything special. Just configured the kernel (make sure the agpgart section in "Character Devices" is marked as well as your chipset and the direct rendering manager with your chipset), compiled and installed it. It is possible, that if you compile agpgart directly into your kernel (not as a module) that you can't list it by lsmod. What I did though was completely recompile and reinstall the mesa and drm/dri drivers for xorg. There are posts on that topic in this forum.

hope it helps

Success!!

Updating to 2.4.27 brought agpgart to life. After that i recompiled mesa and dri/drm according scoob_e's howto.

-> 3d on radon IGP.

Well I have had my bout of success in the time that I thought this thread was dead. I have DRI working, but now my video card is showing symptoms of overheating. I don't think it is overheating though, but I have no real supporting evidence other than when I stick my finger on the heatsink it only feels kinda hot. However OpenGL screensavers and games will freeze at random times. Could agpgart and the internal ati agp thing be fighting over resources?
