The change is actually in the right direction, as the goal is to remove the prototypes from global scope completely. Instead, ISA device drivers should register their interrupt handlers at attach time. I don't know if there's an example of this at the present time. > Particularly I'd like to know if it breaks tha alpha port, or > the new device framework? > As it is now it certainly breaks several automatic build processes I know > of (including the /usr/share/examples/drivers scripts) IMHO, the followup changes have been too slow coming. The new bus framework should completely obsolete interrupt handler prototypes, which may explain the pedestrian pace of the followups. -- \\ 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-current" in the body of the message
