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devo_identify This entry point is obsolete.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).
