dev_ops - device operations structure

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

Solaris DDI specific (Solaris DDI).

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.) Set this to nodev.
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.
