 |
|
Hi...
I have merged the latest Nvidia driver 4349 and i have some questions about the loading of the module.
I have change the /etc/modules.d/nvidia file to:
| Code: |
# Nvidia drivers support
alias char-major-195 nvidia
alias /dev/nvidiactl char-major-195
# To tweak the driver the following options can be used, note that
# you should be careful, as it could cause instability!!
#
# To enable Side Band Adressing: NVreg_EnableAGPSBA=1
#
# To enable Fast Writes: NVreg_EnableAGPFW=1
#
# To enable both for instance, uncomment following line:
#
options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1
|
and then changed in the modules.autoload from NVdriver to nvidia.
I don't know exactly what update-modules does but I have done that.
My question is why aren't NVreg_EnableAGPFW=1 and NVreg_EnableAGPSBA=1 set? Se below:
| Code: |
cat /proc/driver/nvidia/agp/status
Status: Enabled
Driver: AGPGART
AGP Rate: 4x
Fast Writes: Disabled
SBA: Disabled
|
BTW.. Where do I find the glxbear program to measure glx performance?
Is there any other program to measure the graphic performance.
Please help
Regards Lars |

Thanks
received this value:
29419 frames in 5.0 seconds = 5883.800 FPS
Is is good or bad for a Duron 750@900 with Geforce4 Ti4200 64MB?
Anyone that have any idea how I am supposed to do if I want to set
# To enable Side Band Adressing: NVreg_EnableAGPSBA=1
#
# To enable Fast Writes: NVreg_EnableAGPFW=1
I am running kernel 2.5.66 and playing divx movies perform really bad using the mplayer. May the settings above helps it out.. How do I do.

I haven't tried that kernel so I don't know if there are any problems that are specific to it.... guess you could expect it though.
the one problem I had with getting agp set up properly was not having my MTRR set in my kernel (processor type and feature > MTRR )
and you can try using the kernels own agpart support or the one in the nvidia driver (see the nvidia doc for details)

For the record, I didn't emerge the Nvidia kernel. I chose to compile that by hand.
The way I enabled those features with the newest Nvidia drivers was as follows:
1. Download the installer from Nvidia's website. http://download.nvidia.com/XFree86/Linux-x86/1.0-4349/NVIDIA-Linux-x86-1.0-4349.run
2. Run: | Code: | | sh NVIDIA-Linux-x86-1.0-4349.run --extract-only |
3. Edit (use vim or YOUR personal choice of editors) the following file (found under NVIDIA-Linux-x86-1.0-4349/usr/src/nv: os-registry.c
4. Change the following: | Code: |
static int NVreg_EnableAGPSBA = 0;
#endif |
to:
| Code: |
static int NVreg_EnableAGPSBA = 1;
#endif |
and:
| Code: |
static int NVreg_EnableAGPFW = 0;
MODULE_PARM(NVreg_EnableAGPFW, "i"); |
to:
| Code: |
static int NVreg_EnableAGPFW = 1;
MODULE_PARM(NVreg_EnableAGPFW, "i"); |
5. As root, run:
That should do it. I performed those exact steps from a console, logged completely out of X. I also did rmmod nvidia before I started. Don't know if those steps were necessary, but you can never be too safe.
After the make install, FastWrites and SideBandAddressing were enabled.
Hope this helps.

One thing to check is that both your chipset and your card support these. Here is an example from my system:
| Code: |
# cat /proc/driver/nvidia/agp/host-bridge
Host Bridge: VIA Technologies, In VT8363/8365 [KT133/K
Fast Writes: Not Supported
SBA: Supported
AGP Rates: 4x 2x 1x
Registers: 0x1f000207:0x00000104 |
| Code: |
# cat /proc/driver/nvidia/agp/card
Fast Writes: Supported
SBA: Not Supported
AGP Rates: 4x 2x 1x
Registers: 0x1f000017:0x1f000104
|
So as you can see, my chipset can do SBA but not FW while my card can do FW but not SBA. Net result is I'm screwed for both

| SBA is disabled by default in the windows drivers also because SBA turned out to be pretty much useless but seemed to sometimes cause stability problems. |
