DDI_IDEVICE_COOKIE(9S) Data Structures for Drivers DDI_IDEVICE_COOKIE(9S)

ddi_idevice_cookie - device interrupt cookie

#include <sys/ddi.h>
#include <sys/sunddi.h>

illumos DDI specific (illumos DDI). This interface is obsolete. Use the new interrupt interfaces referenced in Intro(9F). Refer to Writing Device Drivers for more information.

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


u_short	idev_vector;      /* interrupt vector */
ushort_t	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.
