  2. Re: [PATCH 2/3] Blackfin Sports UART Driver: fix bug - the bug caused by sport overrun, use timer to flip the tty buffer in order to return from rx ISR quickly


    Can you explain what the timer is for ? If you are trying to push the tty
    processing out of the interrupt handler then surely schedule_work would
    be sufficient. Also if you don't have tty->low_latency set the tty layer
    will already do the actual processing work each timer event not in the
    IRQ.
