MPT_INTERRUPT(9)	     Message-based devices	      MPT_INTERRUPT(9)

NAME
       mpt_interrupt - MPT adapter (IOC) specific interrupt handler.

SYNOPSIS
       irqreturn_t mpt_interrupt(int irq, void * bus_id);

ARGUMENTS
       irq
	   irq number (not used)

       bus_id
	   bus identifier cookie == pointer to MPT_ADAPTER structure

DESCRIPTION
       This routine is registered via the request_irq kernel API call, and
       handles all interrupts generated from a specific MPT adapter (also
       referred to as a IO Controller or IOC). This routine must clear the
       interrupt from the adapter and does so by reading the reply FIFO.
       Multiple replies may be processed per single call to this routine.

       This routine handles register-level access of the adapter but
       dispatches (calls) a protocol-specific callback routine to handle the
       protocol-specific details of the MPT request completion.
