INTERRUPT_DISTRIBUTE(9) Kernel Developer's Manual INTERRUPT_DISTRIBUTE(9)

interrupt_distribute
assign an interrupt to a CPU

#include <sys/interrupt.h>

int
interrupt_distribute(void *ich, const kcpuset_t *newset, kcpuset_t *oldset);

The interrupt_distribute function exists to assign an interrupt to a CPU.

If a driver (or the other kernel component) wishes to assign an interrupt to a CPU, it should pass an interrupt handler such as the return value of pci_intr_establish() as ich argument, and it should pass the kcpuset to which it should be assigned as newset. To get the previous value, pass a non-NULL value to oldset.
