 Posted: Thu Nov 21, 2002 8:36 pm Post subject: Frustrating i845/Nvidia AGP problem |
 |
|
I can't get AGP to run on my system, and could use some help. It a Dell Dimension 4550, which is a P4/i845pe system. It has an Nvidia TI4600 card in it. Video is working great with Nvidia's latest drivers, but I just can't enable AGP for some reason.
I'm wondering if the problems folks are having with the i845 and HD performance (like this one) are also causing me AGP issues.
Here's some info... /proc info first:
| Code: |
jonathan@bigdell log $ cat /proc/driver/nvidia/agp/card
Fast Writes: Supported
SBA: Supported
AGP Rates: 4x 2x 1x
Registers: 0x1f000217:0x00000000
jonathan@bigdell log $ cat /proc/driver/nvidia/agp/host-bridge
Host Bridge: Intel (unknown)
Fast Writes: Supported
SBA: Supported
AGP Rates: 4x 2x 1x
Registers: 0x1f000217:0x00000000
jonathan@bigdell log $ cat /proc/driver/nvidia/agp/status
Status: Disabled
|
lsmod:
| Code: |
Module Size Used by Tainted: P
smbfs 32256 1 (autoclean)
NVdriver 1062976 10
agpgart 25580 0
rtc 6720 0 (autoclean)
|
dmesg output for agpgart (note that it is detecting the chipset as an i845G, but Dell says it is an i845PE, if that makes any difference):
| Code: |
Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 203M
agpgart: Detected Intel i845G chipset
agpgart: AGP aperture is 128M @ 0xe0000000
|
/etc/modules.d/nvidia is configured as below:
| Code: |
jonathan@bigdell etc $ cat /etc/modules.d/nvidia
alias char-major-195 NVdriver
options agp_try_unsupported=1
options NVdriver NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1
|
My device options from /etc/X11/XF86Config:
| Code: |
Section "Device"
Identifier "ti4600"
Driver "nvidia"
#VideoRam 131072
# Insert Clocks lines here if appropriate
Option "ConnectedMonitor" "DFP,DFP"
# Option "UseEdidFreqs" "true"
Option "TwinView"
Option "NvAgp" "3"
Option "MetaModes" "1024x768,1024x768"
Option "SecondMonitorHorizSync" "31.5 - 57.0"
Option "SecondMonitorVertRefresh" "50-90"
Option "TwinViewOrientation" "LeftOf"
Option "NoLogo" "false"
Option "CursorShadow" "true"
EndSection
|
and lastly... from /var/log/XFree86.0.log, the following warnings:
| Code: |
(WW) Open APM failed (/dev/apm_bios) (No such file or directory)
(WW) NVIDIA(0): Failed to verify AGP usage
|
I listed the APM failed message for completeness, not really sure it has any impact on whether AGP is enabled or not.
Anyone see a reason for this problem?
Thanks!

Looks to me from your output of lsmod that you have AGPGART loaded. If you want to use the nVidia AGP support you should likely turn off the AGPGART from inside your kernel, or atleast don't load the module for it anymore. Also the reason your nVidia AGP status is disabled might be by design and you may have to over-ride the default setting if you want it enabled (like all VIA chipset systems do.)
You really ought to read the nVidia driver readme found here.

I get the same situation whether the computer is booted with the linux agpgart or not. My config is set to work with either the linux or the nvidia agpgart, neither works. Morever, it SHOULD work with agpgard loaded.
Been thru that readme a million times, still no dice. Thanks for the suggestion.

What other settings have you tried for the ??
Anything? According to the readme file:
| Code: |
Option "NvAGP" "integer"
Configure AGP support. Integer argument can be one of:
0 : disable agp
1 : use NVIDIA's internal AGP support, if possible
2 : use AGPGART, if possible
3 : use any agp support (try AGPGART, then NVIDIA's AGP)
Please note that NVIDIA's internal AGP support cannot
work if AGPGART is either statically compiled into your
kernel or is built as a module, but loaded into your
kernel (some distributions load AGPGART into the kernel
at boot up). Default: 3 (the default was 1 until after
1.0-1251).
|
Have you tried using the option 2 while using AGPGART? Have you tried removing the AGPGART from your kernel (or do not load the module) and then specify the option 1 to force NVidia's AGP?

Have now tried it four ways - with agpgart loaded, option 2, without, option 1, both loaded and unloaded, option 3.
Same result:
| Code: | jonathan@bigdell jonathan $ cat /proc/driver/nvidia/agp/status
Status: Disabled
|
Thanks.
