I'm trying to DISABLE SBA but this guide won't work for me..
So, the system is an AMD64 on VIA KT800 chipset, GF 6600GT AGP and Kubuntu Feisty and nvidia 1.0-9755
Code:
cat /proc/driver/nvidia/agp/*
Fast Writes: Supported
SBA: Supported
AGP Rates: 8x 4x
Registers: 0xff000e1b:0x1f000302
Host Bridge: PCI device 1106:0204
Fast Writes: Supported
SBA: Supported
AGP Rates: 8x 4x
Registers: 0x1f000a1b:0x00000b02
Status: Enabled
Driver: AGPGART
AGP Rate: 8x
Fast Writes: Disabled
SBA: Enabled
So SBA/FW are supported, FW is Disabled and SBA enabled. I should mention that i also tried this with the NVIDIA AGP driver instead of the default one.
Code:
cat /proc/driver/nvidia/registry | grep AGP
EnableALiAGP: 0
NvAGP: 3
ReqAGPRate: 15
EnableAGPSBA: 0
EnableAGPFW: 0
Judging by the nvidia registry values, SBA should also be disabled. Also, setting these values to 1 doesn't enable FW.. It's pretty clear that they are ignored.
Help?
Edit:
I found out why the options defined in nvidia-kernel-nkc didn't stick.
I had to comment out the lines in this file
Code:
cat /etc/modprobe.d/lrm-video
# Make nvidia/nvidia_legacy and fglrx use /sbin/lrm-video to load
install fglrx /sbin/lrm-video fglrx $CMDLINE_OPTS
install nvidia /sbin/lrm-video nvidia $CMDLINE_OPTS
install nvidia_legacy /sbin/lrm-video nvidia_legacy $CMDLINE_OPTS
install nvidia_new /sbin/lrm-video nvidia_new $CMDLINE_OPTS
Still, the options have no effect on the AGP driver
