Enabling FastWrite & SBA

2uantuM · 05-10-2004, 03:26 PM

How do I go about enabling both of these features? I have done it before, but i cant seem to find the thread were it explains how to do so. I'm running a GF4 ti 4400 on slackware 9.1

root@192:/home/shawn# cat /proc/driver/nvidia/agp/*
Fast Writes: Supported
SBA: Supported
AGP Rates: 4x 2x 1x
Registers: 0x1f000217:0x1f000104
Host Bridge: nVidia Corporation nForce2 AGP (different version?)
Fast Writes: Supported
SBA: Supported
AGP Rates: 4x 2x 1x
Registers: 0x1f000217:0x00000104
Status: Enabled
Driver: AGPGART
AGP Rate: 4x
Fast Writes: Disabled
SBA: Disabled

Kindly,

Shawn

There's no real point, as SBA doesn't give any measurable performance boost, and neither does fastwrites. In fact, fastwrites can cause instability on some motherboards, so it is not recommended.

But to enable them in Linux... not sure how.

exit X by /sbin/init 3 or just init 3
or just kill the proccess.

edit /etc/modules.conf and add (some cases modprobe.conf)

options nvidia NVreg_EnableAGPFW=1
optionsNVreg_EnableAGPSBA=1

after

alias char-major-195* nvidia

you can also adjust bus speed with this line
options NVreg_ReqAGPRate=4 (depending on card) can be 1,2,4 or 8

after that do /sbin/rmmod nvidia
and /sbin/modprobe nvidia

(might not be located in /sbin in your case) might just be the app name.

then start x.

hope this helps!

Thanks, working fine, i was getting lost on http://gentoo-wiki.com/HARDWARE_Nvid...and_Addressing
I just had to edit /etc/modprobe.conf and add:

Code:

alias char-major-195* nvidia
options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1

However..

Code:

# /etc/modprobe.conf (old location for Linux 2.6+ config)
#
# The use of this config file is deprecated.
# Instead, create files in the /etc/modprobe.d/ directory
# containing modprobe options.
