I don't think this makes much sense. Why complicate an interface just to make an already slow processor go unnoticeably faster? -Matt :>> On the 386 and 486, call gates are faster. On the pentium, :pentium-PRO, :>> and pentium-II, interrupts are faster. : :With regards to this, might it not be a good idea to use a different :syscall convention, based on whether you've got the 486/384 options in your :kernel or not? (Plus an additional parameter to completely disable the :multiplexer interrupt, as this should *not* be done until you've rebuilt :everything to use the call gate interface instead ;) : :--- :Marius Bendiksen, IT-Trainee, ScanCall AS <marius@scancall.no> : :To Unsubscribe: send mail to majordomo@FreeBSD.org :with "unsubscribe freebsd-hackers" in the body of the message : Matthew Dillon Engineering, HiWay Technologies, Inc. & BEST Internet Communications & God knows what else. <dillon@backplane.com> (Please include original email in any response) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
