>> 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
