Default 1.0-8774 + FBSD 6.1 & problems with AGP

Hi!

I'm using FreeBSD 6.1-RELEASE (i386), and my problem is related to enabling AGP for my GeForce 6200. When I install 1.0-8774 to use its own AGP driver, and xorg.conf has option "NvAGP" "1", no error messages are shown (neither in dmesg nor in Xorg's log file). BUT, after typing sysctl -a | grep nvidia, there can found the following lines:

hw.nvidia.agp.status.status: disabled
hw.nvidia.agp.status.driver: n/a (unused)
hw.nvidia.agp.status.rate: n/a (disabled)
hw.nvidia.agp.status.fw: n/a (disabled)
hw.nvidia.agp.status.sba: n/a (disabled)


I have Asus A8V Deluxe, which uses VIA K8T800 Pro chipset, and should so be supported by NVIDIA's AGP driver. Altough I'm running Athlon 64 processor, I'm still using 32-bit FreeBSD. I'm confused about this, because when I install 1.0-8774 to use FreeBSD's AGPGART driver, the following statements appear after launching Xorg (option "NvAGP" "2" in xorg.conf):

NVRM: AGP cannot be enabled on this combination of the AMD CPU and OS kernel
NVRM: kernel upgrade recommended.

Why does it say that, even though I'm NOT running anything 64-bit (I know there isn't 64-bit driver available, and I shouldn't even need it)? I do have a pretty rare version of A64 (3500+ Socket 939 with ClawHammer core, stepping and revision aren't usual), which may not be recognized properly by NVIDIA driver. Could this cause the AGP issue?

Thank you.


|EDIT| Running X.org version 6.9.0 and compat5x-i386-5.4.0.8_7 is installed.

Looks like X isn't running. Start X then do a sysctl -a hw.nvidia.

Are you using the x11/nvidia-driver port?

No, X really is running.

Yes. And btw, 1.0-8178 works nicely with FreeBSD's own AGPGART, but as it has the AGP GART interaction bug (fixed in 1.0-8774), the whole system will crash when using an application that uses Xorg's glx module. But at least AGP itself is working..

What kernel are you running?

GENERIC has device agp. This might interfere. Try building a kernel without agp or turn it off by adding hint.agp.0.disabled="1" to /boot/device.hints.

One thing to note though, I've noticed the nvidia-driver port building WITH_FREEBSD_AGP eventhough you select not to use it.

One way I found was this:
cd /usr/ports/x11/nvidia-driver
make extract
make patch
then edit work/NVIDIA-FreeBSD-x86-1.0-8774/src/nv-freebsd.h
look for NV_SUPPORT_OS_AGP make sure it's undef.
make all install if everything is set correctly.
