Optional pointer to an interrupt affinity descriptor. Description WebAnother benefit of using a policy script is that we can set smp_affinity for VFIO IRQs before we return a non-zero value (which will prevent smp_affinity from being changed again). The only potential downside to using a policy script is the minuscule amount of overheard from the script executing for every interrupt, but this should only happen once so it's certainly … birthday countdown template downloadWebMar 30, 2016 · The ISR acknowledges the interrupt and ignores redundant interrupts from the same IRQ, then queues a deferred handler to finish processing the interrupt and stop the ISR from ignoring future interrupts.
