Hello,
I have an ASUS CUV266-DLS motherboard, with an agp-bridge which I think
is supposed to be supported. But it isn't. This is with 2.4.20-rc1, but
I've tried 2.5.47 as well, and haven't seen anything that should have
changed in 2.4.20-rc2 or 2.5.48.
Based on agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: Unsupported Via chipset (device id: 3091), you might want to
try agp_try_unsupported=1.
agpgart: no supported devices found.
I have tried with agp_try_unsupported=1, but no luck. I have seen that
in pci_ids.h this device id is defined to vt8633, so I suppose it should
work. I would really like to know why it doesn't...
Regards,
Stian Jordet

You tried agp_try_unsupported=1 as a modprobe argument,
not as a boot time argument right ?
Quite a few people seem to fall into this trap.
When I get chance, I'll make that a boottime arg too.

You were not really clear here. I tried it as a boot-time argument, because I
have agp-support compiled in. But I guess I could and should try it as a module.
I'll do that now. But why do I have to use agp_try_unsupported=1?

Yup. Then do a `modprobe agpgart agp_try_unsupported=1'

Because if it works, we can then add it to the ID table.

It works, i think. I get this message when I load it:
Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: Trying generic Via routines for device id: 3091
agpgart: AGP aperture is 64M @ 0xf8000000
Thank you very much. I'm very sorry if this was a lame question.
Thanks.

And it survives a 3d app / testgart run ?

No problem. I'll add this ID to the pending patch I have
for Linus to add various other GARTs.

Yes, it does. I have a Radeon 9700 Pro, and I have been running XFree86
cvs to get 2d support. This has worked perfect for me. But yesterday ATI
launched their binary drivers, and I wanted to give them a try. Then I
had to get agp working. And after I got your mail, I thought everything
was going just fine. Everything loaded fine, but the computer locked up
everytime something 3d appeared. At this time I wasn't sure what I
should blame. The driver, og the agpgart. So I found my old Radeon
All-in-Wonder, with good DRI-support, and now it works perfect :)
So to make a long story short (too late), the agpgart seems to work
perfect, altough my Radeon 9700 Pro didn't.

Great! Thank you :)

Bah, I'm not sure anymore. I have two motherboards. Asus CUV-266DLS and
Rioworks SDVIA. Both are dual cpu P3 motherboards. The first has a Via
Apollo Pro 266 chipset, while the Rioworks has a Via Apollo Pro 133A. I
have two graphics-adapters. ATI Radeon All-in-Wonder, and one ATI Radeon
9700 Pro.
With the SDVIA board, I get dri to work with both vga-cards. (On the
Radeon 9700 using the ATI-binary drivers.)
On the Asus, I have to load agpgart with agp_try_unsupported=1. Then I
get the old Radeon AIW to work perfectly with dri, but with the 9700, my
box crashes hard everytime I try anything 3d related.
But this can probably be blamed on the ATI-binary drivers? I just wanted
to let you know.
Best regards,
Stian Jordet

Hi Dave, Stian,
"Same here": The module loads...
However, I have the impression that it doesn't work. I first noticed
that my Xserver was taking 50% of my CPU while playing videos. This
is much less on all other computers that I tried that on.
Turns out that "write bandwidth" to video memory is less than 40Mb
per second. On another system with the same video card, but with a
supported AGP bridge, I get almost 200Mbyte per second. I'll go and
dig for "testgart" and see what that proves....
Roger.
