NAME
       dev_ops - device operations structure

SYNOPSIS

       #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
			This entry point is obsolete. Set to nulldev.

       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).

       devo_quiesce
			Quiesce	 a  device attached to system (see quiesce(9E)
			for more information). This can	 be  set  to  ddi_qui‐
			esce_not_needed()  if  the  driver  does  not  need to
			implement quiesce.
