Idle hands do the daemon’s work

Eirik Nygaard was looking for something to do; Max Laier pointed out removal of #if defined(__FreeBSD__) / #if __FreeBSD_version > 5 would help, and Jeffrey Hsu indicated backporting the UFS2 size extensions would also be good.

I’ll quote my own followup to say there’s plenty of non-coding tasks available, too.

Paying off already

David Rhodus imported Hyperthreading changes from FreeBSD which allow you to automatically use Hyperthreading on supported CPUs with just the regular multiprocessor options turned on in your kernel; e.g. options SMP, options APIC_IO.

However, the DragonFly version has no idling loops in it to reduce CPU resource contention. Because of the way DragonFly schedules per-CPU/sends IPI messages, there’s no performance issue caused by multiple CPUS HLTing. Already, a benefit.

KDE Korrected

Dave Leimbach has added changes to KDE in CVS to allow kdebase to compile on DragonFly. This is in the actual KDE source code, not a ports override.

Hostname, mixer, sound

A bunch of changes came in:

hostname now takes a -r option that will set the hostname based on reverse lookup of an IP address, or -i which does the same using the computer’s primary IP. It also works on IPv4 or IPv6. This very good idea comes from Kent Ibbetson.

mixer has had FreeBSD-5 changes added in. It now can take relative volume changes, thanks to Craig Dooley.

Jeroen Ruigrok added in support for the SoundBlaster Audigy and Audigy 2, apparently sourced from “patches by Orlando Bassotto, which were taken from the ALSA Project and the SoundBlaster OSS repository”.

Booting Fun

Aaron Malone created a patch for src/sys/boot/forth/beastie.4th (now committed) that replaces the ‘beastie’ boot with a dragonfly. He’s working on a dragonfly ASCII console screen saver, too. Now we just need a graphical one too…

pkgsrc pronounced passive

Michal Pasternak posted a plea for use of Pkgsrc to the submit discussion group. Given that he specifically said he wasn’t participating in that group and wasn’t going to do any work to make pkgsrc compatible, and that VFS is not yet complete, that’s probably as far as it will go. I’m editorializing.

Lap relief

YONETANI Tomokazu reported his laptop was running very hot with DragonFly. The CPU was running when it didn’t need to be; Matt Dillon fixed this.

New-SB, clones

The USB system from FreeBSD-5 has been brought in wholesale. Matt Dillon reports his camera, hard drive, mouse, and memory key all working and un/repluggable.

Also, the network interface cloning API from FreeBSD-5 has been brought in, from work by Max Laier and David Rhodus.
