View Full Version : Add new moudle at system starup

December 23rd, 2008, 08:06 AM
I develop kernel module.
i would like to load the module at startup.
i understand i need to add the module to /etc/modules
but where do i put the file ( Which Directory).

There's a directory /lib/modules/<kernel-name>/extra, where you can put new kernel modules.

Naturally, when you update your kernel, your module may (will?) have to be recompiled against the new kernel sources, and the new version placed in the appropriate directory.

thank for the fast replay.
i didn't have the directory extra.
so i created one.
edit the file /etc/modules (Add a line with the name of the module)
it didn't work
Any other suggestion (what am i doing wrong)

You could insert you module (name) into /etc/modules.

Btw, you did not specify where you had installed your kernel module. In other words, where did you place the <kmodule>.ko file?

P.S. Not all *nix systems are setup the same. I assume you are using Ubuntu. If not, please indicate which system you are using.

I use ubuntu.
if you can see my first question, i asked where to put the <module>.ko
file , Where /etc/modules look for external modules

The Way i solved the problem
1. Compile the module against the relevant kernel version.
2. create new directory in /lib/module/KERENL-VERSION/updates
3. The run depmod
4. update /etc/modules - Add a line with the name of the modules.
5. If your driver as input parameters you can use the /etc/modprobe.d/options For Example options module_name param_1=2
