dev_ops(9S)
NAME
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.
