RE: Porting USB stack -- questions on ioconf.c

["Pow, Christopher (SWCOE)" <Christopher.Pow%honeywell.com@localhost>]

Hello Hubert, I've actually solved the problem today working with Jared
McNeill from this list.  It turns out the implementation of malloc() in
my code did not honor the M_ZERO flag, didn't fill the allocated block
with zeros, and thus caused quite a bit of downstream-from-malloc
confusion.

Thanks for your response, though!  I will be sure and post more
questions as I continue on this porting adventure.  I'm sure there's
more crocodiles in the pond.  

As for the operating system I'm porting to:

I can't, but maybe a few hints:
  * ioconf.c is created by running "config KERNELNAME" in NetBSD,
    and it's created in the kernel compile directory (besides ioconf.h)
  * from that, digging into the config(8) program may help
  * also, NetBSD's autoconf system may be useful - see
    http://www.netbsd.org/docs/kernel/programming.html#autoconf and
    http://nixdoc.net/man-pages/NetBSD/autoconf.9.html for a start.
  * Other documentation that may be useful if you haven't found it
    already:
     - http://www.netbsd.org/docs/kernel/ddwg.html
     - http://www.netbsd.org/docs/kernel/pseudo/
     - http://www.netbsd.org/docs/internals/en/

Good luck!

P.S.: What OS are you porting the USB stack to?
