Matthew Dillon has posted his 5th VFS patch; included is some backstory on just how the old and new APIs work.
Month: September 2004
Matthew Dillon wrote that the DragonFly_Stable tag is being moved up to the current code, as his potentially destabilizing VFS work is going to be going into the tree, starting tomorrow.
The moral: if you have production or near-production machines, stick with the stable tag, for now.
If your buildworld chokes on a nonexistent authpf group, read this note from Matthew Dillon.
The recent move to non-GNU patch(1) can cause some trouble building ports. Andreas Hauser has a patch to bsd.port.mk that will fix it until the change can be added “upstream” in the FreeBSD ports collection.
Joerg Sonnenberger has switched the DragonFly version of patch(1) from the GNU version to the BSD-licensed version.
Matthew Dillon gave an answer on the kernel@ list to Magnus Eriksson’s timer question; explaining in the process why DragonFly uses a different timer process than FreeBSD.
Emiel Kollof has posted a patch fixing the NVIDIA binary video driver override; this still does not provide Linuxulator support, but it should otherwise work.
Matthew Dillon’s started work on the new namespace/lookup API – he lists this as “step 5/99”.
Matthew Dillon gave an interesting description of the machines powering the various parts of dragonflybsd.org.
Joerg Sonnenberger posted a note that code added to the project should meet a certain level of WARNS cleanness.
Matthew Dillon cooked a dragonflybsd.org computer recently. It was a backup machine, so no public data was lost.
Joerg Sonnenberger has added a new timer method, for those who are seeing the “high-speed clock” problem:
“Add a new option “TIMER_USE_1″, which allows switching the primary heartbeat from i8254 timer 2 to timer 1. This also reactivates the console beep if TIMER_USE_1 is active.”
It’s “OPTIONS TIMER_USE_1” in your kernel config, if you want to build a kernel that uses this.
This LinuxInsider article about alternative operating systems namechecks DragonFly, though it doesn’t do much more.
Matthew Dillon has committed BSD-licensed versions of
dc, ported from OpenBSD by Sascha Wildner.
There is now a “stable” cvs config file at
/usr/share/examples/cvsup/DragonFly-stable-supfile for tracking the known stable point in DragonFly code. Added by Matthew Dillon.
Joerg Sonnenberger warned that a full buildworld will be needed when next upgrading your system. You will also want to recompile any ports that use cam/libcam, like many CD-reading tools.
The aforementioned bug in compiling KDE 3.3 on DragonFly seems to be getting straightened out.
Matthew Dillon, on users@, gave a short outline of how to buildworld/kernel on a different, faster computer, and then move to another machine to install.
There is now a mailing list specific to the Installer program. Email email@example.com – subject: subscribe
Emiel Kollof has posted bug 89544 for KDE 3.3.3, for getting KDE to compile on DragonFly. It may be worthwhile to register on KDE’s Bugzilla and vote for that bug, so that it gets “on the radar”.
Update: There’s related bug 89577 too.
Update update: Joerg Sonnenberger noted (see bug report linked above) that the DragonFly code can be changed to make this work, though the Single Unix Specification implies that the problem is with where KDE is looking. Quote below:
Joerg Sonnenberger has commited a whole pile of updates to various network drivers, among them axe(4). He warns that anyone with a axe(4) device should give it a whirl, as the driver is untested at this point.
ps (from Matthew Dillon’s recent change) is now able to show which processes are and are not holding the “Big Giant Lock”, a symptom of multiprocessor use inherited from FreeBSD.
If you aren’t familiar with the BGL, Greg Lehey wrote a good explanation in Daemonnews. (look for the section labeled “The SMP Problem”)
The list archives now are tracking messages on the new firstname.lastname@example.org list.
“Users”, a new list/newsgroup for “general, non-kernel postings” is available.
Mail “subscribe” to email@example.com.[excised to spamprotect] to sign up.
This thread started by Joshua Coombs names some good resources to start with if you plan to learn programming in C.
Apparently, a history of CVS commits to the Installer is available. There’s some mentions of the installer and OpenBSD in recent commits…
Someone got 5th edition Unix running on a Game Boy Advance, in a demo loop of sorts. I’m linking to this not because it has any real use, but because the page also contains a nice history of very early Unix.
Jeroen Ruigrok/asmodai has added a dfport override for devel/apr, the APache Portable Runtime, which happens to recognize DragonFly.
Joerg Sonnenberger’s committed YONETANI Tomokazu’s changes to the ips driver, for RAID devices such as ServeRAID. Among other benefits, it now supports more recent Adaptec hardware.
Joerg Sonnenberger has imported a new wi(4) driver for 802.11, taken from FreeBSD. Update: if this new driver doesn’t work for you, use owi(4), which is the older version.
Matthew Dillon noted in this post to kernel@ that he anticipates 64-bit work in perhaps 6 months, after VFS is completed.
‘Rum’ has started work on dfport overrides for KDE 3.3.0. (The link he supplies appears not to work yet, however.)
cu program has been out of the system for a long time; Matthew Dillon has committed
cu emulation in
Spam was being placed in the comments for various entries on this page at the rate of 1 every 10 minutes or so; I’ve changed the setup to block most of it. If you post a comment and it doesn’t appear immediately, it may be waiting for approval.
Matthew Dillon pointed out that when comitting functional changes to the DragonFly source, keep them separate from other modifications. That way, when other BSDs/projects use these modifications, it will be much easier for them to review and use.
Simon ‘corecode’ Schubert is looking for more information on finite state automatons, since a number of them appear in the DragonFly source.
forknibbler.com now lists the DragonFly docs that are located there, including a PDF version of the Handbook.
