ide_intr - default IDE interrupt handler : interrupt number : hwif : unused weirdness from the kernel irq layer
This is the default IRQ handler for the IDE layer. You should not need to override it. If you do be aware it is subtle in places
hwif is the interface in the group currently performing a command. hwif->cur_dev is the drive and hwif->handler is the IRQ handler to call. As we issue a command the handlers step through multiple states, reassigning the handler to the next step in the process. Unlike a smart SCSI controller IDE expects the main processor to sequence the various transfer stages. We also manage a poll timer to catch up with most timeout situations. There are still a few where the handlers don't ever decide to give up.
The handler eventually returns ide_stopped to indicate the request completed. At this point we issue the next request on the port and the process begins again.
