It sets the configuration 51machinery in motion by finding the root bus ("mainbus"). When this 52function returns, interrupts must be enabled. 53.Pp 54.Fn cpu_configure 55performs the following tasks: 56.Bl -bullet 57.It 58initialize soft interrupts (see 59.Xr softintr 9 ) 60.It 61initialize CPU interrupts and SPLs 62.It 63call 64.Fn config_rootfound 65for "mainbus" 66.It 67complete any initialization deferred from 68.Fn cpu_startup . 69.El 70.Sh SEE ALSO 71.Xr autoconf 9 , 72.Xr cpu_startup 9 73
