Hi Folks, I observed that, even after linux boots and INIT process starts, rs_timer stays active and causes the rs_interrupt_single to be called.
I saw a posting on rs_timer on this message board by mvista, which says ---------- > Once you hit userland, /dev/ttyS0 is opened and serial I/O is normally interrupt driven. Prior to that it uses the polled serial console routines in the driver. Now, the rs_timer() kludge claims to work for non-interrupt driven I/O but I've never heard of anybody using it. You should just hook up your interrupt controller. ---------- If this is true, after INIT process is invoked, why does the rs_timer function is called? ByTheWay, my interrupt controller is on.
