Close. Static configuration bases everything on resources incorporated at compile time, yes. Dynamic configuration uses resources available at run time; not just user input before/during the boot process. In the context above, the key features of a "dynamic" approach include: - The ability to create/delete new instances of a driver. - The ability to create/delete new instances of a bus. - The ability to retain parametric hints for unknown driver instances. - The ability to obtain and manage resource information. - The ability to load/unload code supporting new devices/busses. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
