RE: Help - how to let a module load another module

[l x <whereisit28@yahoo.com>]

Thanks so much for the information and sorry for not making myself clear.

 

The details are like this:

 

- modA.o needs to be loaded first and it will do some

  work after been loaded.  After the work is done,

- modB.o needs to be loaded.

 

Is there a system call, something like "load_another_lkm"?  If there is one, then we can call it from modA after modA completes its works.

 

Thanks,

I've never done this but I believe it works like this.

 

Copy your LKM's to somewhere under the tree:

   /lib/modules/<version>

 

where <version> is the current kernel version ('uname -r').

 

Then run depmod.

 

depmod should create the module dependency file. This determines interdependencies between LKM's.

The module dependency file will live here:

   /lib/modules/<version>/modules.dep

 

Then load your modules using modprobe.

 

Thus if modA.o  depends on modB.o

Then the command:

 

# modprobe modA.o

 

...should load modB.o and then modA.o

 

I'm sure someone will correct me if I'm wrong.

Subject: Help - how to let a module load another module

Hi,

 

People usually use insmod to load a module from the command-line.  How can we let a module load another module?  Suppose we have module_a.o and module_b.o, how to code module_a, so running "insmod module_a.o" will cause module_b.o loaded.

 

Thanks,
