Paolo, so would it be correct to say that INTR_FILTER is designed to make life much easier in view of shared interrupts. >From the code it seems that there would be virtually no difference when there are no shared interrupt, but with shared interrupts INTR_FILTER removes all the churn and makes interrupt handling nice and clean (from device drivers point of view). -- Andriy Gapon _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
