Then I'm definitely opposed :-) Here's a sketch of my world view, which matches the newconfig code a little: isa <-> pcic <-> pccard slot 0 <-> driver(s) for card in slot 0 pccard slot 1 <-> driver(s) for card in slot 1 or the more complicated card bus: pci <-> cbb <-> pccard slot 0 <-> driver(s) for card in slot 0 pccard slot 1 <-> driver(s) for card in slot 1 card bus slot 0 <-> driver(s) for card in slot 0 card bus slot 1 <-> driver(s) for card in slot 1 The card bus machines would provide attachments to both a pccard slot (for pccard devices in a card bus capable slot) and a card bus slot. Multiple children would be allowed per slot to support multi-function cards. It is my understanding that these cards share an interrupt, but otherwise function indepenently. I hope to have something to share for the pcic and cbb drivers before freebsdcon. However, I suspect that hammering out everything is going to take a while yet. I'm looking for ways to open up the development process. Keep your eyes peeled to -mobile for ways of doing it.
