A running description of activity related to DragonFly BSD.
Sascha Wildner has posted a patch that makes it very easy to switch out the compiler used to build DragonFly. This builds on earlier work from Alex Hornung.
This should make it into the base system. Everyone’s looking at compilers that aren’t gcc these days, it seems.
The pkg_radd(1) and pkg_search(1) utilities defaulted to pkgbox.dragonflybsd.org. They’ve been switched (by me) to point at avalon.dragonflybsd.org, which has much more bandwidth.
Matthew Dillon’s added AHCI as a kernel module, and has directions for testing. It’s not done, but he has basic hot-plug support in, among other things.
I’ve been posting a lot of “hey test this new technology” items, lately. That’s good. Since I haven’t done it already, here’s a description of AHCI.
Sepherosa Ziehau has added support for various power states on AMD Phenom and Turion-series processors. He has some specific notes that mention there’s more processor family support on the way. Good news for anyone with an AMD-based laptop.
Alex Hornung posted a summary of how his work on devfs is going, and Jordan Gordeev posted a summary of how much AMD64 is functional.
If you want to try either one (warning: many parts still broken!), use a vkernel for the devfs so a physical system doesn’t get broken. There’s build instructions for pulling together AMD64 DragonFly.
Update: manual instructions for AMD64, too.
Dru Lavigne’s excellent book ‘BSD Hacks’ is available at Scribd, and a chunk of it is readable through the preview at that site. A good chunk of what’s in there applies to DragonFly.
My copy is sitting on the shelf near by, inbetween ‘Perl Best Practices‘ and ‘The Mythical Man-Month‘.
The DragonFly mirror at dragonflybsd.kiev.ua went down due to hard drive failure some time ago, but it has returned. It’s an honest-to-goodness DragonFly system now too, I think. It’s (re)listed on the mirrors page.
As Hasso Tepper says, please don’t bring in any major changes until after DragonFly’s 2.4 release. This is mostly for the benefit of pkgsrc, so that we can have as complete a working set of packages as possible at release time. 2.4 will probably be in July.
While asking some questions, Alex Hornung let drop some of the details of his Summer of Code devfs project. Sounds like he’s making good progress.
Huawei modems, often available as USB attachments, have been problematic on DragonFly. However, it looks like it’s fixed. (I dont have one to test.) There’s a lot of names involved, so I’ll just point to the commit message.
When DragonFly was moving away from CVS, the votes were split pretty evenly between Git and Mercurial. DragonFly went to Git, but it’s apparently now possible to use Mercurial with a Git repository.
Statis Kamperis is working on POSIX conformance for DragonFly as his Summer of Code project; he’s posted some questions about the agreement he is given for the Open Group’s test suites. If you’re curious, he links to a copy of the agreement. (I have an I-am-not-a-lawyer-but-have-worked-on-a-number-of-contracts followup)
Matthew Dillon has put together some new test machines, in preparation for porting the OpenBSD AHCI driver to DragonFly. Check his message if you are thinking about building a new system, as they appear to work well.
Hasso Tepper has a “BIG FAT WARNING” about two new issues: threaded programs are broken on bleeding-edge DragonFly because of a possible GCC bug that was only recently exposed, and Xorg in pkgsrc has issues with the Intel driver.
Simon ‘corecode’ Schubert already has one change in that may fix the issue with threaded programs, and is working on the Intel driver issue.
Update: more threading changes.
Sdävtaker is giving a “Hammer administration” presentation at BSDDay, May 29th and 30th in Argentina. (His presentation is the second day.)
Jordan Gordeev posted installation instructions for his ‘BTX Halted’ fix. It may not be the final answer, though.
Another Summer of Code summary: Jordan Gordeev is returning to AMD64 work. He appears to be ahead of schedule, too.
Dan Chis has posted a summary of his Summer of Code project: debugging multi-threaded applications. He also has some details of his current thesis in there… He’s busy.
Hasso Tepper has some xorg updates to fix problems he’s seen with the intel video driver. The versions of these packages in pkgsrc are old enough that the changes can’t be committed ‘upstream’ to xorg, so he’s attacking the problem from the opposite direction and upgrading the software.
He reported significant EXA performance improvements, so it’s definitely worthwhile. It’s tested on DragonFly but will probably benefit other pkgsrc-using platforms too.
Sepherosa Ziehau’s recent commit changing how ioapic works may help anyone who has previously had trouble compiling a multiprocessor kernel with IO_APIC enabled. Try it, if that applies to you.
Also, Jordan Gordeev has a potential fix for anyone who has had a failed boot with a ‘BTX Halted’ message; you will have to retrieve it from his Git repo.
