Chris Buechler found out that varsyms don’t work (yet) on a per-jail basis. Darn.
I’ve been remiss, and haven’t mentioned YONETANI Tomokazu’s ACPI patches. They aren’t in the tree yet, but if you have a laptop and want to try them out, they are at http://les.ath.cx/DragonFly/.
Joerg Sonnenberger has committed GCC 3.4. To use it, update, and then set CCVER=gcc34.
Having trouble with loading a splash screen? “beastie_disable=YES” in your /boot/loader.conf. Note: this may or may not work; it’s untested.
A number of people reported issues compiling a kernel after the recent crtbegin/crtend file changes from Joerg Sonnenberger. This is now fixed by Joerg and Matt Dillon.
Running DragonFly under VMWare? Try GeekGod’s XF86Config, if you don’t have one set up.
This should be bugfix week; DragonFly BSD 1.0 should be ready for USENIX, starting on the 27th in Boston. This week may be rather quiet…
After several iterations, we now now a “offical” archive of discussions on the dragonflybsd lists. This pulls right from the news server. It’s currently updated every 2 hours. Credit’s due to Matt and Hiten for hitting me with ideas for it, and for adding the support applications.
There’s still some work to be done: Search functions, raw messages, and archive downloads. That’ll be the next version.
Other archives out there:

The DragonFly Live CD with installer now includes a web-based installer in addition to the existing ncurses installer.
Hiten Pandya posted that work for DragonFly 1.0 should be done by June 13th, which gives a week of testing before USENIX.
(flop sweat time!)
I had been thinking, “How big a market is there for BSD-based systems?” Netcraft’s very nice websurver-survey shows just how much, at least for FreeBSD and webhosting. It also shows something else – the Internet/computer market is definitely back into a growth cycle.
Matt Dillon committed the MSFBUF API. His commit note sums it up nicely so I’ll repaste:
” Add the MSFBUF API. MSFBUFs are like SFBUFs but they manage ephermal multi-page mappings instead of single-page mappings. MSFBUFs have the same caching and page invalidation optimizations that SFBUFs have and are considered to be SMP-friendly.
Whereas XIO manages pure page lists, MSFBUFs manage KVA mappings of pure page lists.
This initial commit just gets the basic API operational. The roadmap for future work includes things like better interactions with third-party XIOs, mapping user buffers into the kernel (extending the xio_init_ubuf() API into the MSFBUF API), and allowing higher level subsystems to pass previously released MSFBUFs as a hint to speed-up regeneration. We also need to come up with a way to overload additional sets of MSFBUFs representing smaller chunks of memory on top of the same KVA space in order to efficiently use our KVA reservation when dealing with subsystems like the buffer cache.
MSFBUFs will eventually replace the KVA management in the BUF/BIO, PIPE, and other subsystems which create fake linear mappings with pbufs. The general idea for BUF/BIO will be to use XIO and MSFBUFs to avoid KVA mapping file data through the nominal I/O path. XIO will be the primary I/O buffer mechanism while MSFBUFs will be used when things like UFS decide they need a temporary mapping.
This is a collaborative work between Hiten Pandya and Matthew Dillon .”
Matt Dillon noted that removing ‘device ehci’ from your kernel configuration will cause the USB 2.0 ports to switch down to USB 1.1. This may be needed to make certain USB chipsets work.
Munish Chopra pointed at this mailing list post as the possible reason you see -DTARGET_NAME=\”i386-undermydesk-freebsd\” when building GCC3.
A link getting passed around is this list of OSX optimizations. Joerg Sonnenberger commented on it in the GoBSD forums, listing what’s possible and what’s done already in DragonFly.
Hiten Pandya has now added a ‘-O’ option to top which switches between the display of threads only, or processes and threads.
Since we’re still using the ports system, you can speed installs up significantly by using prebuilt packages. There’s package repositories at Fortunaty.net and GoBSD.com.
