WebMay 23, 2024 · IPIs include the type of interrupt (i.e. INTR, SMI, NMI, INIT, SIPI) and the destination. Each logical processor has an APIC-ID, which is . If the IPI's destination matches its ID, it handles the interrupt. Otherwise it ignores it. WebCPU X queues up the new csd structure to CPU Y's call_single_queue; CPU X then sends an interprocess interrupt (IPI) to CPU Y; Oftentimes, CPU X will then wait for the work to finish in order to make sure it can safely proceed; CPU Y receives the interrupt and works csd's in its call_single_queue; CPU Y then acknowledges the csd completion
