Nested Interrupts on Single Processor System.
Posted 10-25-2011 at 05:28 AM by pmehtal
Hi,
I do have following query regarding nested interrupts on the single processor system i.e.
Does nested interrupt appear only if there exists irqaction(s) whose irqaction->flags does not set SA_INTERRUPT ?
I mean that if all irqactions has set the SA_INTERRUPT flag then there is no scope of execution of nested interrupt(s) on the single processor system.
Thanks.
