Below is a message I posted to x11@ regarding an apparent problem I am havi=

with a new mobo and getting DRI support. At the very least, it appears tha=
t=20
my AGP is not being probed correctly, and I hope that is where my DRI probl=
em=20
lies. The mobo is an ECS 755-A2 (Athlon 64 socket 754, but I am running=20
i386, not amd64, and this is a fairly recent 5.3-STABLE) using the SiS 755=

chipset. I do not find this listed in src/sys/pci/agp_sis.c It appears a=
=20
guess is being made that this is a SiS 650 chipset, based on the output fro=
m=20
pciconf -lv: device =3D 'SiSM650? Host-to-PCI Bridge' .
The device ID for that chipset (taken from agp_sis.c) is 0x06501039, but=20
pciconf shows mine to be 0x07551039. Presumably I can add another conditio=
n=20
to the case statement the generates that information and it will at least I=
D=20
correctly, but I've never done that and I want to make sure I do it correct=
ly=20
before trying it. I would think something along the lines of:
case 0x07551039:
return ("SiS 755 host to AGP bridge");
but is all that going to accomplish is fixing the ID or is there more that=

needs to be done?

Subject: Radeon DRI problems after system upgrade

I recently (this weekend) upgraded my aging P-III system to an AMD Athlon 64
(still running the i386 version of FreeBSD) and DRI has stopped working. I
am running a recent 5.3-STABLE with Xorg 6.8.1 and the current graphics/dri
from ports. AGP is compiled into the kernel. The chipset is SiS 755. I
receive the following error now when drm0 loads:
Jan 9 04:27:17 gw kernel: agp0: binding memory at bad offset 0
Jan 9 04:27:17 gw kernel: error: [drm:pid688:radeon_cp_init] *ERROR*
radeon_cp_init called without lock held
Jan 9 04:27:17 gw kernel: error: [drm:pid688:radeon_unlock] *ERROR* Process
688 using kernel context 0
=46rom postings to mailing lists, this indicates that AGP is not loaded, bu=
t I
made sure to build it statically into the kernel when I first noticed the
problem. Here are some particulars:
Jan 9 04:27:17 gw kernel: drm0: <ATI Radeon QY RV100 7000/VE> port
0xd000-0xd0ff mem 0xe8020000-0xe802ffff,0xe0000000-0xe7ffffff irq 16 at

Jan 9 04:27:17 gw kernel: info: [drm] Initialized radeon 1.11.0 20020828 on

pciconf -lv reports the following for AGP:

and for drm0:

DRI used to work with this release of Xorg and the same -STABLE sources.=20
From old syslogs:
Dec 27 21:09:44 gw kernel: agp0: <VIA 82C691 (Apollo Pro) host to PCI bridg=
e>
mem 0xe4000000-0xe7ffffff at device 0.0 on pci0

Dec 27 21:10:00 gw kernel: info: [drm] Initialized radeon 1.11.0 20020828 on

My only guess is that this has something to do with AGP support for this
chipset. Does anyone have a suggestion?
