SYNOPSIS

#include <sys/ddi.h>

#include <sys/sunddi.h>

INTERFACE LEVEL

Solaris DDI specific (Solaris DDI).

DESCRIPTION

The ddi_idevice_cookie_t structure contains interrupt priority and interrupt vector information for a device. This structure is useful for devices having programmable businterrupt levels. ddi_add_intr(9F) assigns values to the ddi_idevice_cookie_t structure members.

STRUCTURE MEMBERS

u_short

idev_vector;

/* interrupt vector * /

u_short

idev_priority;

/* interrupt priority * /

The idev_vector field contains the interrupt vector number for vectored bus architectures such as VMEbus. The idev_priority field contains the bus interrupt priority level.
