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 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.
devo_power: Power a device attached to system. See power(9E).
