Linux kernel support pass param to kernel, this params can be assigned at load time by insmod or modprobe.  or later read from /etc/modprobe.conf file.

There are two macro : module_param and module_param_array, 

To declare an param or array param ,use:

module_param(name, type, perm)   module_param_array(name, type, num, perm)

name is the name of your param or array.

type can be : bool ,invbool,charp, int, long, short, uint, ulong, ushort

num is the array num , array param where the values are supplied as a comma-separated list.

perm : S_IRUGO , S_IWUSR and so on .

int num = 0;static char* array[10] = {NULL};static int ntime = 0;static char* pstring = NULL;module_param_array(array, charp, &num, S_IRUGO);module_param(ntime, int, S_IRUGO);module_param(pstring, charp, S_IRUGO);static int __init init_func(void){        int i = 0;        printk("string :%s, int :%d\n", pstring, ntime);        printk("Array\n");        for(; i < num; ++i)                printk("%s\n", array[i]);        return 0;}

执行：

sudo insmod ./hello.ko array="hello,world" pstring="test" ntime=10
