I started porting a pseudo driver from OpenBSD and had the same issues. You could find more info here: http://www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/index.html http://www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/newbus-api.html http://www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/driverbasics-char.html#AEN8703 And this come in very handy: FreeBSD Source Code Tour: http://snapshots.jp.freebsd.org/tour/ A nice website provided by Robert Watson (Thanks!!!): http://fxr.watson.org/ Looking at existing code is also good, like the simple led driver by phk@ There was also a thread where John Baldwin described the parts of a driver but I can't seem to find it. -- Joao Barros _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
