I'd like to do it in the other order and bind everything, so things like the per-CPU TCP timer thing can be flipped on for RSS and actually be useful. I'm looking into what it'd take to create a separate default swi as well as a cpu-0 swi but as I said, it's pretty hairy there. How about i instead do the comprimise: * i'll pin all other swi's * default swi isn't pinned by default, but one can flip on a sysctl at boot time to pin it How's that sound? -a _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
