Hi,
I have been looking at the linux serial driver initialization routine rs_init() in drivers/char/serial.c. This routine gets invoked as a part of a do-while loop in do_initcalls() in init/main.c.The code looks something like this:
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();
}
I would like to know where exactly is rs_init() being inserted into the chain of routines that gets invoked in the do-while loop.
I see that initcall_start is placed in the init section of the code segment.I see a lot of init routines starting at initcall_start in the System.map file.
TIA
Manoj
