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

NAME

ddi_idevice_cookie - device interrupt cookie

SYNOPSIS

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

INTERFACE LEVEL

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 This interface is obsolete.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.

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.
