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.
