Then it's just a matter of cleaning up, running software interrupts, and getting back to regular work. The "regular work" may well have changed as a result of an interrupt (the handler could wake_up a process, for example), so the last thing that happens on return from an interrupt is a possible rescheduling of the processor.The concept of an interrupt is something that has expanded in scope over the years. The 80x86 family has only added to the confusion surrounding interrupts by introducing the int (software interrupt) instruction. Indeed different manufacturers have used terms like exceptions faults aborts traps and interrupts to describe the phenomena this chapter discusses. Unfortunately there is no clear consensus as to the exact meaning of these terms. Different authors adopt different terms to their own use.
