Well, first I'd like to backup user space drivers are the way to go. They are
just more flexible.
Where a linux kernel driver comes in handy is sharing bus ressources between
different applications. Ok, we have owserver for that but then, all the
applications have to use owfs.
I specifically think of onewire chips built into laptop batteries. As soon a
user encounters such a device, wants to monitor it through the usual kernel
hardware monitoring interfaces *and* connects some devices to the laptop
through owfs (e.g. servicing my vending machine), he will run into
a "deadlock".
Ok, as far as I read it, w1 isn't connected to the hardware sensor facility so
far, but it may come up.
Kind regards
