DEVICE_PROBE_AND_ATTACH(9)				   BSD Kernel Developer's Manual				DEVICE_PROBE_AND_ATTACH(9)

NAME

     device_probe_and_attach -- initialise a device

SYNOPSIS

     #include <sys/param.h>
     #include <sys/bus.h>

     int
     device_probe_and_attach(device_t dev);

DESCRIPTION

     This function is called during autoconfiguration to initialise the devices in the system.	For each device, the DEVICE_PROBE(9) method of
     each suitable driver is called and if a probe succeeds, a description of the device is printed and the DEVICE_ATTACH(9) method is called.	If
     the device is disabled using device_disable(9) then it will not be probed.

RETURN VALUES

     Zero is returned on success, otherwise an appropriate error is returned.

SEE ALSO

     device(9), driver(9)

DEVICE_ATTACH(9)					   BSD Kernel Developer's Manual					  DEVICE_ATTACH(9)

NAME

     DEVICE_ATTACH -- attach a device

SYNOPSIS

     #include <sys/param.h>
     #include <sys/bus.h>

     int
     DEVICE_ATTACH(device_t dev);

DESCRIPTION

     Attach a device to the system after the DEVICE_PROBE() method has been called and has indicated that the device exists.  The DEVICE_ATTACH()
     method should initialize the hardware and allocate other system resources (such as devfs(5) entries).

     Devices which implement busses should use this method to probe for the existence of devices attached to the bus and add them as children.	If
     this is combined with the use of bus_generic_attach(9) the child devices will be automatically probed and attached.

RETURN VALUES

     Zero is returned on success, otherwise an appropriate error is returned.
