Abstract: Disclosed are various embodiments for decreasing the amount of time spent processing interrupts by switching contexts in parallel with processing an interrupt. An interrupt request can be received during execution of a process in a less privileged user mode. Then, the current state of the process can be saved. Next, a switch from the less privileged mode to a more privileged mode can be made. The interrupt request is then processed while in the more privileged mode. Subsequently or in parallel, and possibly prior to completion of the processing the interrupt request, another switch from the more privileged mode to the less privileged mode can be made.
