 Posted: Sat Dec 02, 2006 2:49 pm Post subject: Loading module options [solved] |
 |
|
Hi there, i need to run my spca5xx module as the following command line for it to produce a bright enough picture to see properly.
I was wondering what the correct way is to run these options everytime the module is asked to load.
I have tried to insert
| Code: | | options spca5xx GRed=500 GBlue=500 GGreen=500 gamma=4 |
command directly into my /etc/modules.conf file
I also tried to enter both spca5xx and (on another boot) spca5xx GRed=500 GBlue=500 GGreen=500 gamma=4 into my /etc/modules.autoload.d/kernel-2.6 neither seem to work and my webcam loads with a dark screen. However, when i rmmod spca5xx , and then manually type in modprobe spca5xx GRed=500 GBlue=500 GGreen=500 gamma=4 it works fine and dandy 
Can anyone suggest a sure fire way of getting the module to load with the options I specify anytime and EVERYtime without the hassle of rooting and entering it manually ?

Unclethommy,
Add | Code: | | spca5xx GRed=500 GBlue=500 GGreen=500 gamma=4 |
to /etc/modules.autoload.d/kernel-2.6
This works if the spca5xx is actually loaded from here.
You cannot edit /etc/modules.conf directly. Its created at every boot by concating all the files in /etc/modules.d/
To add things to /etc/modules.conf, make a new file in /etc/modules.d/ (any name you like) and put your options there.
Now run modules-update to recreate /etc/modules.conf without a reboot.
To test do | Code: | modprobe -r spca5xx
modprobe spca5xx |
your kernel needs to support module unloading for this to work

what does dmesg say after adding your options to your /etc/modules.autoload.d/kernel-2.6 ? Don't know any more if it's necessary, but perhaps you have to invoke a modules-update after inserting your options.

I took all the references out of the files I mentioned to see if that stopped the module loading. Spca5xx still loaded and is visible in lsmod after the reboot. I will try to change the autoload file as youve suggested and reboot to see what dmesg says too....
I have change part of my udev rules so that the camera node is /dev/mywebcam
Would this effect the module loading? Just athought.
EDIT: okay, after boot, it still is dark as reported before... I check on dmesg heres the part with the first message of spca5xx

Could there be something else running spca5xx automatically ? |

Unclethommy,
I suspect its the part of udev that replaced coldplug.
Unplug the webcam, | Code: | | modprobe -r spca5xx |
Now plug in the cam again. With modules.conf updated to include the options, I expect they will be applied. If so, that confirms its udev loading modules for equipment attached at start up.
In a corner of my mind, I have an inkling that udev can apply module params too. It can certainly run scripts, which would be a messy way to do the same thing. Its all here

Neddyseagoon,
Your hunch was right. The module seems to be automatically loaded.
