How is this meant ? Who will convert it and when ?
I tried. At the time Luigi's PnP code was added, this was accompanied
by a paper from him on how the code works and how to add pnp drivers
(and this example also shows, that it is possible to write docs and
drivers!).
I miss this information for the new PnP way badly. But obviously it is
not done with the new pnp code, but it interacts with the new-bus code
somehow for which i even more miss intros and docs.
Don't misunderstand me, i appreciate the work on this very much, but
the more "undocumented" code and methods go into this area of FreeBSD
the more this area will go from an open system to a closed system which
only few will then understand and be able to maintain.
Please - write a short paper like Luigi's about how it works and how
to add a driver to this framework! It reduces the load for the
architects and let them do architectural work - and it enables people
like me to maintain their drivers and saves everyone from asking
dumb questions like the one above.
I currently don't see how to convert this stuff myself.
