Description

The interrupt_ack_fn_t function is called by an interrupt target to ack an interrupt. Returns the interrupt vector.

typedef int (*interrupt_ack_fn_t)(conf_object_t *NOTNULL);

Interface for acked interrupts. The target is typically a cpu that later calls the supplied ack function when the interrupt is actually taken.

typedef struct interrupt_ack_interface {
        void (*raise_interrupt)(conf_object_t *NOTNULL obj,
                                interrupt_ack_fn_t, 
                                conf_object_t *);
        void (*lower_interrupt)(conf_object_t *NOTNULL obj,
                                interrupt_ack_fn_t);
} interrupt_ack_interface_t;
