.Sh SYNOPSIS
.In sys/param.h
.In sys/bus.h
.Ft void
.Fn bus_set_pass "int pass"
.Sh DESCRIPTION
The
.Nm
function is called during boot to raise the bus pass level to
.Fa pass .
The function will rescan the device tree for each pass level between the
current pass level and the new level that has at least one associated
driver.
The device tree rescans are implemented by invoking the
.Xr BUS_NEW_PASS 9
method on the root bus device.
