Hi,
Thanks for ur earliers replies. They helped me a lot
in understanding the newbus architecture.
I am involved in a freeBSD port to a freescale board.
I still had a few doubts:
I am looking at the autoconf.c file for the i386
architecture.
When i/o configuration is in progress during startup,
are the drivers for specific busses alreay assosciated
with them or the association happens at run time ?
for example :
when nexus is being attached to root_bus,
the method devclass_find_internal("nexus", 0, TRUE) is
invoked(in method make_device).Now does a nexus
devclass already exist ( it is created through the
macro DRIVER_MODULE(nexus, root, nexus_driver,
nexus_devclass, 0, 0);) or it is created at runtime ?
if it is created at runtime how the nexus_driver get
assciated with nexus?
Thanks,
Alok.
