Hi all,
I am going through the kernel bootup sequence.
When the function do_initcalls() is called
The definition of the function is;
static void __init do_initcalls(void)
{
initcall_t *call;
call = &__initcall_start;
do {
(*call)();
call++;
} while (call < &__initcall_end);
/* Make sure there is no pending stuff from the initcall
sequence */
flush_scheduled_tasks();
}
1. Here __initcall_start variable is being used. But I couldn't understand
what it is? Where it is being initialized ??
2. What is role of these *.S files like the arch/sh/boot/compressed/head.S
files in the linux kernel.??
Could u pls help me out in this regard?
