 Posted: Mon Apr 05, 2004 8:33 pm Post subject: Falling back of AGP to 2x mode althoug it is a 4x AGP Nvidia |
 |

Well I noticed that the kernel falling back to AGP2 instead of 4x
Apr 5 20:19:01 [kernel] agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0.
Apr 5 20:19:01 [kernel] agpgart: Device is in legacy mode, falling back to 2.x
how to tell kernel to use AGP4x or is that based on nvidia card?

| maybe your mainboard doesn't support agp 4x mode. please refer your user manual, to check if it does. |

its an ABIT IC7 with i875Chipset and 8x Support so I think its not the mobo..also the graficcard is a MSI Geforce 4 TI4200 2x down capatility /4x
maybe the latacy mode is the problem but dont know hoiw to fix or solve that

And why you use agpgart instead of NVAGP ?
add this to section device of Nvidia card in XF86Config

If i use this option my system got instable and crash | Code: | agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0.
agpgart: Device is in legacy mode, falling back to 2.x
agpgart: Putting AGP V2 device at 0000:00:00.0 into 4x mode
agpgart: Putting AGP V2 device at 0000:01:00.0 into 4x mode
nvidia: no version magic, tainting kernel.
nvidia: module license 'NVIDIA' taints kernel.
1: nvidia: loading NVIDIA Linux x86 NVIDIA Kernel Module 1.0-5341 Fri Feb 13 13:49:23 PST 2004
0: NVRM: not using NVAGP, AGPGART is loaded!! ----> is that the module versioning support? |
also it said cant load NvAGP

If you have Nvidia graphic card you should use NVAGP instead of agpgart.
Try rmmod agpgart and then add
to XF86Config ...see documentation here
ftp://download.nvidia.com/XFree86/Linux-x86/1.0-5336/README

| Also, in that doc it says that NVAGP can't work if you're kernel already has agpgart loaded. Agppart has to be either a module that isn't loaded or not built into your kernel at all. |

Yes it is best solution and make sure that you have not agpgart builded directly in the kernel.
P.S. - And NVAGP is not unstable. It works quite fine.

foton2 maybe your system differs from mine so I guess it a system like behavior...to me it is quite a bit unstable...diont know if I can put it to preempt kernel..and SMP support will test and verifiy
