Hi,
The purpose of this post is to let you know what the NetBSD project
has been up to lately, what the cool stuff is coming down the pipe,
and more general information dissemination.
[This document is the result of a number of contributions, and is thus
a little less than perfect]
Meta stuff:
First, the members of the NetBSD project have little time to read
news. Regardless of whether you post a bug report to
comp.os.386bsd.*, please send your bug reports to
'netbsd-bugs@sun-lamp.cs.berkeley.edu'. If we don't at least
acknowledge your bug report promptly, let us know.
We are making changes in the way we do "business" in order to provide
better technical support. In particular, we will be switching to a
more integrated bug report management scheme (likely GNATS) such that
bug reports do not fall between the cracks. This "database" will be
manned by a much larger group of people than were ever on the
netbsd-bugs list. Expect announcements from us on how all this is
going to work later in the week.
Use the mailing lists. Some people have been using the list of
contributors at the end of the TODO file as a mailing list. We would
prefer that you use one of the standard lists like 'netbsd-comments'
instead.
To make it easier for you to get involved in the NetBSD project, and
to reduce our own load, the NetBSD mailing lists are now under
Majordomo, a mailing list maintenance tool. If you mail
'majordomo@sun-lamp.cs.berkeley.edu', you will receive information on
which mailing lists are available, and how to subscribe. Note that
some of the more obscure mailing lists are closed (have owners) for
noise reasons. Contact the owners of those lists if you feel you need
access. Also be warned that a re-organization of the mailing lists
internal to netbsd is coming soon. Hopefully this transition will be
smooth and without incident. This re-organization will reflect a
desire for a greater signal to noise ratio.
Look for a change in the 'doc' directory structure in the coming
weeks. This change will seperate the documentation, changes, bugs,
todos, and installation docs that are machine-independent from those
that are port-specific.
Status/On-going projects:
(all of this is post-NetBSD 0.9, so presently this code is only
available via the NetBSD-current distribution (sup or tar). The next
release though should include some or all of the stuff discussed below)
(assume bugs fixed throughout)
Shared libraries support
Paul Kranenburg and company have done a sun-like dynamic
library scheme that meets our specs. It hasn't been committed to our
tree yet, though some software has been upgraded to the level necessary
to make it all work. It is designed to be easily ported to other
architectures, and already works on i386 and sparc.
There is still some important work to be done, but the core is present.
Obviously we will let you know how this progresses.
Magnum branch
A branch of the tree that works more like 4.4. It eases the porting of
4.4-oriented ports to NetBSD. It uses config.new, some of the BSD 4.4
ideas on scheduling, clocks, and profiling, and is a general
code improvement in flexibility over the net2 code. This branch is
not currently available to the general public yet, but
arrangements can be made. It will be rolled into the mainline code
in the relatively near future.
i386 port
multiport serial boards
cyclades cyclom-8y (and 4/16y) multiport async serial
support is now in the tree
support for some of the digiboard multiport cards should be
forthcoming soon. Two seperate groups have come forward with
drivers that need further testing, and debugging.
serial i/o - a driver rewrite is in the immediate plans of at
least 4 NetBSD people. At worst, we will do a bakeoff.
a re-org/re-work of the i386 autoconfiguration support including
interrupts, dma, etc. This should allow for a better
'GENERIC' kernel, and will probably include bounce buffers
and the like. This work is part of the magnum branch,
and will appear when it gets merged into the mainline tree
MacBSD or NetBSD/Mac
pre-alpha release went out.
more robust release expected any day now
current release can be had on sun-lamp:/pub/NetBSD/mac
Mailing lists are:
macbsd-general@sun-lamp.cs.berkeley.edu
macbsd-development@sun-lamp.cs.berkeley.edu
mail 'majordomo@sun-lamp.cs.berkeley.edu' to join them.
hp300 port
this port runs, works fine, and is in regular use. A
distribution will be prepared soon. Contact Charles Hannum
<mycroft@sun-lamp.cs.berkeley.edu> for more info.
Sun3 port
It fails to exec init since I haven't compiled one. Otherwise
this port is in need of drivers, and some integration work with
the mainline tree. Currently hamstrung by personal resource
issues. Looking for people who can take it the rest of the way.
mail 'glass@sun-lamp.cs.berkeley.edu'.
Mailing lists are:
sun3-port-helpers@sun-lamp.cs.berkeley.edu
use majordomo as described earlier to subscribe.
Amiga port
This port is being actively distributed.
netbsd-amiga@cbmuucp.commodore.com is the main mailing list
and mail netbsd-admin@... to subsribe.
distribution available from
nic.funet.fi:pub/unix/NetBSD/NetBSD-amiga
more info available from comp.unix.amiga and Markus Wild
<mw@sun-lamp.cs.berkeley.edu>
Sparc port
Succeeds in exec'ing /sbin/init, and in mounting sunos filesystems.
Expected to go single-user very soon. People who wish to debug kernel
panics can send deraadt@fsa.ca mail, but no earlier than oct15
as there's still much to be done. Requires magnum branch.
Mips port (actually decstations)
The 4.4 decstation code has been donated to us by the authors,
Rick Macklem and his compatriot. They want to see the code
merged into NetBSD but don't have the time to do this by
themselves. No one has stepped forward yet witht the appropriate
combination of time, knowledge and resources. Interesting parties
should contact me <glass@sun-lamp.cs.berkeley.edu> and I'll refer
you to the appropropriate parties.
General Changes
more base improvements to baseline code portability and overall
stability (see changes list appended below)
fsclean support - basically marking ufs filesystems systems as
clean if unmounted properly to speed reboots. Code is from
Andrew Herbert. This is mostly in the tree now and should be
activated soon.
Posix stuff - more utilities, functions made posix.2 compliant
A serious amount of kernel work fixing bugs, improving stability,
adding functionality, and improving portability. This is
detailed further in the Changes list below.
These are the changes we've logged to the NetBSD source pool since
NetBSD 0.9. This does not reflect some of the work being done in
branches, or committed in batches by off-lamp developers. To get
access to this pre-next-release work, you must fetch the
NetBSD-current sources. There should be information about this in the
install notes.

Wow..you got all the way down here. If you have any comments, mail
them to netbsd-comments@sun-lamp.cs.berkeley.edu
