Hi everybody,

(I'm sorry if i'm not in the good thread...)

I've Installed the nvidia drivers with emerge
and do all the stufs in the HowTo Install Nvidia drivers
and all the others stufs that i've a found about it.

But i wanted to active the NvAgp so i disable agpgart
i my kernel and test it in a x server with glxgears
and everything seems fine.. (I have 12000 fps with
the windows by default in 1680x1050 with à 9700 GS)

so I wanted to verify if all my config where good
(and if the fastwrite and blablabla were activated
correctly....)
and I run : less /proc/drivers/nvidia/agp/status

but the path doesn't exist !!!

not agp directory
I have cards/0, warings/... , registry and version but not
the stuf to verify i AGP is really activated...

What Have i done bad ????

If Someone have an idea, it would be great !!!

Thanks a lot, i'll give all the information that you
need to help me

9700GS? i guess you mean 7900GS, right? That's not an agp card, but pciexpress. That's why the agp gart module (nvidia's or kernel's) is not loaded. It's perfectly fine..

Hi, thanks for the answer...

yes it's a 7900 (excuse me)...

so is there any means to test my config
to know if i've done all the stuff good ???

(a pciexpress slot in /proc or a benshmark
programme ??? )

and why agpgart he's loaded if there's
not any agp ??? because on WinXP (sorry)
the agp module and testing in DirectX is
active ...

so it's a pciexpress, yes but maybe the driver
act with it like an agp modules....

and why in the howto (from nvidia and gentoo)
there is only an explenation with /proc/drivers/nvidia/agp...

thanks a lot if someone can help me...

Angel

You should do:
Code:
 cat /proc/driver/nvidia/registry
and notice the following two entries:
Code:
EnableAGPSBA: 0
EnableAGPFW: 0

you're perfectly fine. even though glxgears is really not a bench app, 12000fps shows that everything is ok. Btw, even if you try to load the agp module, it won't be used by the driver by any means if it's pciexpress. Also if
Code:
glxinfo |grep "direct rendering"
shows "yes" than it means that everything installed properly. and btw, obviously the howto is for agp based cards..
