dev_ops - device operations structure

---

SYNOPSIS

#include <sys/conf.h>
#include <sys/devops.h>

INTERFACE LEVEL

Solaris DDI specific (Solaris DDI).

DESCRIPTION

dev_ops contains driver common fields and pointers to the bus_ops and/or cb_ops.9s

Following are the device functions provided in the device operations structure. All fields must be set at compile time.

devo_rev

Driver build version. Set this to DEVO_REV.

devo_refcnt

Driver reference count. Set this to 0.

devo_getinfo

Get device driver information (see getinfo.9e

devo_identify

Determine if a driver is associated with a device (see identify.9e

devo_probe

Probe device (see probe.9e

devo_attach

Attach driver to dev_info (see attach.9e

devo_detach

Detach/prepare driver to unload (see detach.9e

devo_reset

Reset device (Not supported in this release).

devo_cb_ops

Pointer to cb_ops.9s structure for leaf drivers.

devo_bus_ops

Pointer to bus operations structure for nexus drivers. Set this to NULL if this is for a leaf driver.
