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 devo_identify This entry point is obsolete.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). STRUCTURE MEMBERS
