Why does it need to put in devsw before probe ? How about: probe (may examine sysctl for hints) attach (may examine sysctl for hints) devsw reg. sysctl reg. devfs reg. > I was thinking of having an 'info' page for each device in devfs > # cat /dev/fd0.info > Floppy Disk > IRQ=6 > DMA=4 > capacity=1.44MB > driver version 1.45 > # > sounds like sysctl is trying to do the same thing.. I would argue that we should not do this in devfs. I don't like to mix the functionality. If anything, we should make a sysctlfs then, even though I don't like that idea too much either. > I don't quite understand how devconf and sysctl go together.. > do they? devconf hijacked sysctl to get info from kernel to user and back. -- Poul-Henning Kamp | phk@FreeBSD.ORG FreeBSD Core-team. http://www.freebsd.org/~phk | phk@login.dknet.dk Private mailbox. whois: [PHK] | phk@ref.tfs.com TRW Financial Systems, Inc.
