Passing an array as command line argument for linux kernel module

Question

I would like to pass an array of data to the Linux kernel module.

In the kernel:

 int a[5]; 
 int count;
 module_param_array(a, int, &count, 0);

But I've no idea how to pass values from the command line. If it is a just variable I will use:

insmod k1.ko a=10 

Answer 1

You can pass arrays via

 insmod k1.ko a=10,20,30,40

see Linux Kernel Module Programming for more information and examples.
