a20

Description

This interface is used between the A20 line handling device (typically the keyboard controller) and the x86 processor. The processor implements this interface and the keyboard controller calls it.

SIM_INTERFACE(a20) {
        void (*set_a20_line)(conf_object_t *NOTNULL obj, int value);
        int (*get_a20_line)(conf_object_t *NOTNULL obj);
};
