Synopsis:

#include <qvm/vdev-core.h>

struct vdev_pic_functions {
    unsigned flags;
    unsigned pnum_mask;
    int (*signal)(const struct guest_intr *gip, enum guest_intr_state gis);
    void (*notify)(const struct guest_intr *gip, enum guest_intr_notifications gin);
    const char * (*parse)(struct guest_intr *gip, const char *name);

Data:

unsigned flags: PIC-specific flags.
unsigned pnum_mask: The param mask that isolates the pin index number.
int (*signal)(const struct guest_intr *gip, enum guest_intr_state gis): Assert or de-assert an interrupt pin.
void (*notify)(const struct guest_intr *gip, enum guest_intr_notifications gin): Indicate which operations should call guest_intr_notify().
const char * (*parse)(struct guest_intr *gip, const char *name): Convert a param value referenced by gip into a string.
size_t (*string)(const struct guest_intr *gip, char *buf, size_t buf_len): Convert a param value referenced by gip into a string.
ssize_t (*table_spec)(const struct guest_intr *gip, enum guest_table_spec_component component, void *buf, size_t buf_len): Convert *gip into the format required by a firmware table.
