As of past night, the macppc and shark ports have support for the new-style kernel modules. I've added support for these through a workaround in the build system, which makes the compiler generate long jumps for all calls in the code, avoiding unsupported ELF relocation types. This allows us to use the modules even if the kernel-level loader is not able to deal with such relocations. The kernel-level support is now enabled by default in macppc and shark GENERIC kernels.
We'll need to revisit this in the future and implement real support for dealing with those relocation types. Why? The modules built with this flag are slower than they should be... but at least they do work.

Hardware accelerated X for Rev. 4 Sharks using the xf86-video-chips driver has been around for a while but Rev. 5 Sharks were stuck with a dumb framebuffer driver. This has changed, a few days ago I committed an Xorg driver for the IGS CyberPro 2010 graphics controller found in Rev. 5 Sharks.

In September this year, Guillaume Lasmayous spent 5 weeks in the US where he took the opportunity to meet with some developers from the NetBSD project. On a Saturday afternoon Guillaume met Christos Zoulas to answer a few questions about NetBSD.

The opengrok code search and cross reference service has been set up and is available at:
It contains the NetBSD sources which are updated every three hours.
This service is running on NetBSD-5 using opengrok with openjdk from pkgsrc.
Happy Grokking :)

In BSD Magazine issue 4/2009 I write about out-of-the-box support for sshfs on NetBSD 5.0. The article goes over the basic principles, use, tuning, and features in store beyond NetBSD 5.0. See the magazine website for purchase/subscription instructions.

Here is my summary of project goals and results for Lloyd Parkes' Summer
of Code project, Miniaturize NetBSD.
Lloyd's project was concerned with helping developers to build small,
bootable NetBSD system images by extending NetBSD's cross-compilation
toolset and adding new kernel facilities.

The work to improve the parity handling in RAIDframe was done by Jed
Davis as a 2009 Google Summer of Code project in NetBSD. The
mentoring on this project was done by Greg Oster. This document
summarizes the project and the results.
RAIDframe (the software RAID implementation in NetBSD) suffers from
long parity checking/rebuilding times in the event of an unclean
shutdown. The goal of this project was to implement a solution that
greatly reduces the amount of time required to ensure that the parity
is correct after an unclean shutdown.
The main project goals were met. Jed's solution to the parity
rebuilding problem is based on a "parity map". In this solution, the
RAID set is divided into some number of "zones", where the parity
status of each zone is reflected in the parity map. So while the
existing RAIDframe code can be though of as having just a single zone
(i.e. the entire RAID set) the new parity map code uses simple
heuristics (e.g. minimum zone size of 25MiB per component, maximum of
4096 zones) to determine the number of zones and the size of the
Part of the work involved exploring various zone sizes and
investigating the performance implications of not only the zone sizes
but the frequency of updating the parity map as well. There were also
data consistency (e.g. order of write operations) and update issues
(e.g. drive cache flushing) to deal with.
The code has yet to be merged into the main NetBSD tree, pending
additional testing and verification of the code involved.

ISC has informed us of network maintenance to happen between 14:00 and 15:00 UTC today (Oct 8th).
This concerns most public services directly under NetBSD.org (including this blog).
Expected outage duration is 20 minutes. Please stay calm :)

Around 00:00 UTC on 2009-09-25, nyftp.netbsd.org will be offline for an
unknown interval of time due to the emergency replacement of a chiller
and other air conditioning equipment at the location where it is hosted.
The current expected date for the return of services is ~2009-09-28.

blog.NetBSD.org was not very available between ~13:00 and ~20:00 UTC today.
One of its disks semi-failed and led to really exhaustive retries that left the httpds so exhausted they timed nearly everybody out instead. The faulty disk has been taken offline, and lo, we have a blog again.
