nforce2 agp

[svoelker]

Looks like we're getting closer to having AGP support for the nforce2 chipset. According to the change log on http://linuxhq.com the 2.4.21-rc5-ac1 kernel has "NVIDIA AGP support", which I assume means "nforce AGP support". Has anybody had a chance to check it out?

I checked out the source of 2.4.21-rc5-ac1 and it contains the patch for nforce2 agpgart.
I didn't have the chance to test the patch, but ist should work...

I managed to compile and install the kernel. I haven't tested it thoroughly, but so far everything seems to be working.

I also tested (2.4.21-rc5-ac2) but it doesn't work properly here.
If I use testgart then everything seems to be ok, but when I start X the windows are drawn only in parts. Also the system locks... I have to push reset to reboot.
I also tried 2.5.70 and the nVidia kernel patch, but none of them worked for me. I always get the error thet is explained above.
For some reasons the patch provided by nonolk works perfectly for me...

My hardware:
Asus A7N8X Deluxe
nVidia GeForce 2 Ti (I know... I don't need agpgart...)

To bad it isn't working for you. Are you using the nvidia graphics driver for your card? You might have some conflict, since the nvidia driver comes with its own agpgart. I have no problems running X and it seems to be stable so far. Also, I only have tried the XFree86 4.3 stock radeon driver. I haven't had a chance to try the ATI drivers yet.

MSI K7N2
Ati Radeon 9500 Pro
