[solved] AGP is missing?

eilenbeb · 2009-03-09 19:09:37

Hello all. I've just installed Arch 2009.02 x86-64 (and updated successfully). I've stumbled through the guides, forums, and wiki to get X, IceWm, Alsa, and a handfull of other things up and running.

Ran into a problem with 3d acceleration, however. After some searching and command-line-salad I discovered that AGPGART isn't loaded.
Heh, I can't even -find- agpgart.

snippet:

[eilenbeb@aCore X11]$ lsmod | grep agp
[eilenbeb@aCore X11]$ lsmod | grep ag
snd_page_alloc         11792  2 snd_emu10k1,snd_pcm
[eilenbeb@aCore X11]$ lsmod | grep gart
[eilenbeb@aCore X11]$ modprobe agpgart
FATAL: Module agpgart not found.
[eilenbeb@aCore X11]$

I even ran depmod and tried "modprobe agpgart" again.
I also can't find any reference to AGP under /lib/modules/2.6.28-ARCH.

Sorry to bug the forumers, but I'm coming up empty on this one.
nvidia 7800gs (agp 8x)
nvidia nforce3 250 (not the pro version)
amd athalon64 FX-51
sucessfully installed 'nvidia' and 'nvidia-utils' using pacman.

laters,
b

Updates.
Under /lib/modules/2.6.28-ARCH/kernel/drivers/char/agp I found Via, SiS and Intel agp's.
In modules.dep and modules.alias I also found Via, Intel, and SiS. No Nvidia.

I found a /sys/bus/pci/drivers/agpgart-amd64 folder, but there doesn't seem to be anything human-readable inside.

Try

hwdetect --show-agp

eilenbeb · 2009-03-09 20:47:43

No output.

[eilenbeb@aCore ~]$ hwdetect --show-agp
[eilenbeb@aCore ~]$

and also, because I didn't post it before,

[eilenbeb@aCore ~]$ lsmod | grep nvidia
nvidia               8119960  26 
i2c_core               26144  2 nvidia,i2c_nforce2
[eilenbeb@aCore ~]$

It appears something is wrong with the detection of your motherboard/chipset .

try

lspci -vk

as root

partial output of that command on my system :

edit--- You beat me to the post, hang on.

Hmm... I just fired up an install of Ubuntu-minimal with xorg, icewm, nvidia-glx-new and some 3d apps.
lsmod isn't showing any agp there either... maybe I'm looking in the wrong direction here.

Maybe all the AGP stuff is handled by the nvidia driver ad I should be looking at my X configs.
Dunno. Any ideas?

The hostbridge item in the ouput is missing a kernel module.

In the kernel sources folder drivers/char/agp i found a module that supports the athlon64 / nforce3 agp :

amd64-agp , try modprobing this module.

If that fails, you can try nvidia-agp
Nvidia-agp is for the nforce2 chipset, so amd64-agp should be the first try.

Note: the kernel sources are not available as arch package, if you want them just download them from www.kernel.org
I tend to keep an extracted copy of a recent kernel source on my system, they often are handy.

Are you sure your system has AGP? If it has it should be detected, I would think. I know that my default installation of Arch does detect the AGP in my machine.
Perhaps, especially if you have relatively new hardware, you have PCI-E in which case you are in an even better position as it is superior to PCI and AGP since it can run up to 4 times faster than AGP 8x.
Since I do not have PCI-E I'm not sure what would be reported as but I would expect that "lspci" would tell you something.

The hostbridge item in the ouput is missing a kernel module.

...so it is. I must boot up Ubuntu (where OpenGL is working great) and check the output there.

I tried those earlier, but couldn't find any .ko files.

[eilenbeb@aCore ~]$ modprobe amd64-agp
FATAL: Module amd64_agp not found.
[eilenbeb@aCore ~]$ modprobe nvidia-agp
FATAL: Module nvidia_agp not found.
[eilenbeb@aCore ~]$

Modprobe is turning the dash into an underscore, I noticed.

@ralvez: Absolutely sure. AGP 8x and not PCI-E. How did you get your AGP detected? It looks like I'm missing a kernel module.

Thanks for the replies.
Gotta go to work for a while, I'll work on this more this evening.
laters,

Well ... that's the thing: I did not have to do anything special, it was detected.
When I do (as root) hwdetect --show-agp I get : AGP : agpgart intel-agp

I never had to do anything whatsoever to get support for it.

broch · 2009-03-09 22:34:43

if you installed nvidia driver then it is using internal agp. If you don't want any problems don't try to use kernel agp it is slow. In fact quite often intel/sis/via are blacklisted as these may only cause problems..

Thank God that nvidia driver will prevent the above from starting (usually)
Now you don't have any of the above. You do have nvidia based mobo and nvidia video card. So you can use kernel agp (slow) or nvidia internal AGP (called NVAGP)

to get 3d acceleration, you need to configure X
Section "Module"
Load "glx"

Section "Device"
Identifier "Device0"
Driver "nvidia"
Option "NvAGP" "" <------------------------ see below
Option "RenderAccel" "1"

Section "Extensions"
Option "Composite" "Enable"
Option "RENDER" "Enable"
Option "DAMAGE" "Enable"
EndSection

This is important:
Option "NvAgp" "0" disables AGP support <------------------- emergency if AGP fail or if you have PCIE (no AGP card)
Option "NvAgp" "1" use NVAGP, if possible <---------------------- best, but sometimes may be difficult
Option "NvAgp" "2" use AGPGART, if possible
Option "NvAGP" "3" try AGPGART; if that fails, try NVAGP

Hope this will help.

That worked, marking as solved.

Thanks everybody. Not only is it fixed, but I learned a few things along the way.
Now I'm off to find out more about the driver-specific options (if someone were to post back and point me in a good direction, it wouldn't hurt my feelings).

On a side note, these entries aren't in my Ubuntu xorg.conf. Maybe they're hidden in another file? Maybe not needed in the older versions? I'll try looking into that, too.

laters all,

edit...followups:
I found the Nvidia xorg.conf options at http://us.download.nvidia.com/XFree86/L … dix-b.html
Nvidia documentation for the 180.29 driver seems pretty thorough, start at http://us.download.nvidia.com/XFree86/L … index.html
