I may be wrong, it was time ago, but I think I've seen they doing some timer stuff within each interrupt handler. FreeBSD neither has unified place to do it now, nor I much like to add some overhead to every possible interrupt in a system. Present implementation supposed to be a compromise. -- Alexander Motin _______________________________________________ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
