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.
