To do that i've added new functions ipi_self () and ipi_self_from_nmi (), utilizing xapic's ability to send. Handlers loop until they do not see zeroed scoreboard generations. So, i'm doing a lot of smp tests in my kernel, and it seems my ipi's are barely working. This, together with hardware keeping one pending ipi in lapic irr should prevent lost shootdowns. Cases where my ipi works: But i have a slight problem with keeping the fallback ipi functionality in the root interrupt controller. Attaching a handler to the clock software interrupt thread and using this flag when scheduling a software interrupt handler can be used to implement the functionality performed by setdelayed. Memory order all memory operations that happen before triggering an ipi, via ipi_trigger (), ipi_trigger_multi (), ipi_trigger_broadcast (), ipi_unicast (), ipi_multicast (), or ipi_broadcast (),.
