31.Sh NAME
32.Nm bus_generic_new_pass
33.Nd "generic implementation of BUS_NEW_PASS for bus devices"
34.Sh SYNOPSIS
35.In sys/param.h
36.In sys/bus.h
37.Ft void
38.Fn bus_generic_new_pass "device_t dev"
39.Sh DESCRIPTION
40This function provides an implementation of the
41.Xr BUS_NEW_PASS 9
42method which can be used by bus drivers.
43It first invokes the
44.Xr DEVICE_IDENTIFY 9
45method for any drivers whose pass level is equal to the new pass level.
46Then, for each attached child device it calls
47.Xr BUS_NEW_PASS 9
48to rescan child buses,
49and for each unattached child device it calls
50.Xr device_probe_and_attach 9 .
