ddi_idevice_cookie

- device interrupt cookie

Synopsis

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

Interface Level

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 This interface is obsolete.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

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 bus-interrupt levels. ddi_add_intr(9F) assigns values to the ddi_idevice_cookie_t structure members.

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.
