dev_ops(9S)

NAME

dev_ops − device operations structure

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

Solaris architecture specific (SunDDI).

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:

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_rev Driver build version.

devo_refcnt Driver reference count.

devo_cb_ops Pointer to cb_ops(9S) structure for leaf drivers.

devo_bus_ops Pointer to bus operations structure for nexus drivers.

Drivers should set the following fields at compile time:

devo_rev to DEVO_REV.

devo_refcnt to zero.

devo_bus_ops to NULL if this is for a leaf driver.
