This discussion of cryptographic hardware for FreeBSD may include hardware that would work for DragonFly too. Can someone verify?
Sascha Wildner has added system management BIOS (SMBIOS) support, visible with kenv, from FreeBSD. Use it for getting things like the BIOS revision, system manufacturer, and so on. For example:
smbios.bios.reldate="12/04/2006" smbios.bios.vendor="Dell Inc. " smbios.bios.version="2.1.0 "
This may seem minor, but this can be very helpful when dealing with hardware you aren’t physically able to access.
Today is the day that FreeBSD moves to using clang by default. This is not necessarily a surprise, but I like the finality of calling it “Clang-Day”. I think Clang will probably be the next compiler brought into DragonFly’s base system, instead of the next release of gcc. Don’t make any bets on my statement, though, cause I certainly won’t be the one doing it. (It’s hard.)
John Marino is working on a very good idea: bringing bmake into DragonFly as a replacement for the current ‘make’. bmake is going through more active development and apparently also in use/will be used? on FreeBSD, so syncing up with the same make flavor as FreeBSD and NetBSD will help everyone. It’ll also remove the problem where you ‘make’ everything in DragonFly, except pkgsrc packages which you ‘bmake’. It’s not changed over yet.
(What does OpenBSD use for make?)
Sascha Wildner has committed Markus Pfeiffer’s port of USB4BSD to DragonFly. USB network, input , audio, and storage devices (including xhci/USB3 items) may work, though there’s no guarantee for each driver. This is added but not on by default, so see the first link for instructions on how to rebuild your kernel to use it. This will be in (but not default) the DragonFly 3.2 release.
(This is shaping up to be a much bigger release than I anticipated!)
NYCBUG, the NY BSD user’s group, has an RSS feed for their speaker events, found via Dru Lavigne’s always useful BSD Events twitter. The next event at the start of October is a talk about SMPng in FreeBSD. Given that it was the project that in part led to the creation of DragonFly, I’d like to hear about it. (and even better, have someone more qualified than I compare and contrast that approach with what’s in DragonFly.)
This recent question asked on-list about creating your own file system meandered into good reference books. This so far was “The Design and Implementation of the FreeBSD Operating System“, “Modern Operating Systems“, and the paper “Vnodes: An Architecture for Multiple File System Types in Sun UNIX“. Looking for links on those things led me to this Unix filesystem history paper from IBM, which is fun reading.
I’m saying that unironically! It really is an interesting document to read, for historical and general knowledge. I am a nerd.
Adrian Chadd has apparently been smushing FreeBSD onto MIPS systems for some time, and he’s going to talk about it tomorrow night at the NYCBUG meeting. I’m noting it because I’ve always found it interesting how much can be stripped out of a kernel and userland and still have a functional system.
More benchmarks, in this case a comparison of Debian GNU/kFreeBSD and DragonFly. I’m not even sure how to derive meaning from it.
A few recent updates imported to DragonFly from FreeBSD: Francois Tigeot updated amdsbwd(4), an AMD south bridge watchdog. Sascha Wildner updated arcmsr(4), the Areca RAID controller driver, and Peter Avalos updated pw(8).
In the other direction, FreeBSD now has GNU hash support for rtld, based on John Marino’s work in DragonFly.
The FreeBSD Foundation is putting out their end of year donation notice. Donate if you can; the support for active developers there helps everyone.
Yep, fall hits and it’s easier to find links.
- DragonFly morphology. The insect, not the operating system, though that would make an interesting diagram.
- Stick your pinkie in the corner of your mouth, Dr. Evil style, and say, “One MEEELion TCP connections on BSD!“. (via several retweets)
- Sudo vs. SSH public keys.
- The app store concept is taking over. Not that it’s a totally bad thing! We could implement one for pkgsrc, and should. (via)
- A nice (OpenBSD-centric) walkthrough of routing. (via)
- Ooh, decent disk benchmarks. I wish there were graphs, of course.
- I think this happens to most CS grads; you sit around one day and say to yourself, “Hey, I could write an operating system!” This forum post shows someone getting that idea and then realizing it’s not necessarily the goal he wanted. Why do I link to it? I appreciate the optimism.
- Or you can just build a functioning computer in Minecraft. This sort of thing has been happening for a while – this movie is just a link to the craziest example I’ve seen so far.
Your unrelated link of the week: Scientific Illustration. Not a comic, but still visually interesting.
Google’s announced the accepted projects for 2011. DragonFly has 6 slots!
We had a large number of interesting project proposals; far more than than the slots available. If you’re one of the students who did not get in, please consider working on your project as time allows. I know it won’t be lucrative, but I’d still like to see them happen.
Here’s the list of accepted projects:
- Implementing a mirror target for device mapper: Adam Hoka, mentored by Joe Talbott
- Improve dsched interfaces and implement BFQ disk scheduling policy: Brills Peng, mentored by Alex Hornung
- Make vkernels checkpointable: Irina Presa, mentored by Venkatesh Srinivas
- Port PUFFS from NetBSD/FreeBSD: nickprok, mentored by Nathaniel Filardo
- Bring kernel event notification in DragonFly BSD to its logical conclusion: Samuel J. Greear, mentored by Sascha Wildner
- Porting Virtio Drivers from NetBSD to DragonFly BSD to speed up DragonFly BSD as a KVM guest: Stéphanie Ouillon, mentored by Pratyush Kshirsagar
February’s BSD Magazine is headlining “ZFS on FreeBSD”, along with a bunch of other material, including an interview/example for the next BSDCan convention. There’s some BSD-project-specific news in there from this site about DragonFly, along with MirOS, MidnightBSD, and FreeBSD.
(I ran out of alliterative words, sorry.) Venkatesh Srinivas has committed his work on memory allocation; his commit message has details. He’s kindly provided a link to the article that inspired the per-thread magazine work. He’s also provided graphs to show comparative performance benefits of his new memory allocator on DragonFly and on FreeBSD.
- The BSD Certification Group needs reviewers for the BSDA exam objectives. It’s as easy as writing on a wiki.
- Undeadly has a lengthy article up about the OpenBSD equivalent of pkgsrc bulk builds, called dbp3. Interesting, because it was constructed on purpose, for that purpose. It’s interesting to me because I have pbulk running all the time, and it’s not as liner a process as I’d like.
- The PC-BSD installer is now present in FreeBSD; I think this is based on the same original installer used for DragonFly. Maybe, maybe not, but I’m curious about the feature set if it’s able to displace the venerable and firmly lodged FreeBSD sysinstall.
- Off topic: I bought an Android-based phone recently, so this (kinda grody) comment on how Apple handles bad reception for the new iPhone is entertaining.
- Really off topic: this man’s conversation about polyhedral dice (Youtube) is strangely compelling. You may or may have needed to play tabletop games previously to really appreciate it. (via)
Sascha Wildner has ported MultiMedia Card support from FreeBSD; SD, SDHC, and MMC cards should work in DragonFly now. Man, there’s been a lot of new additions recently.
Rui Paulo’s work porting the current set of FreeBSD network drivers over to DragonFly has been committed; there’s about a zillion commits (via Matthew Dillon) today to show for it.
Gergo Szakal mentioned some ideas he had about binary upgrades; among other parts of the conversation, Samuel J. Greear/Sascha Wildner reminded everyone that Matthias Schmidt had ported the FreeBSD binary upgrade system over in late 2007, and it’s still around to play with.
That was fast – there’s another BSDTalk already! BSDTalk 186 has Jeff Roberson, FreeBSD committer. He’s talking about schedulers and softupdates for a good half hour.
Matthew Dillon declared his intention to have REDO working for Hammer very soon. This will improve speed by lowering the number of fsync()s needed in a given period of time to flush data to disk.
It’s New Year’s Eve Eve, and so here are a bunch of links I’ve built up over the past few days.
- Hubert Feyrer posted notes on how to mount fixed disks in KDE. This probably works on NetBSD, but I bet it would work on DragonFly too…
- pcc is now able to build an OpenBSD i386 kernel. Will it work for other BSDs? I hope so, eventually.
- The FreeBSD Foundation is in the last hours of donation for 2009 – give if you get a chance. Did you know they get Bad Code Offsets, like carbon offsets? I did not know such a thing exists, though it makes sense.
- Brian Kernighan talking about Elements of Programming Style, in video. (via) Kernighan’s book, “The Practice of Programming“, with Rob Pike, is an excellent read.
I’ve been building this entry up for a while, so some of these entries are newer than others.
- From the howling void: OpenSolaris or FreeBSD. I’ll admit I haven’t tried OpenSolaris, but I’m also biased to BSD.
- cpdup, originally-on-DragonFly software, has had an update.
- This description of the Content Pyramid talks about web content and links, but it could be stretched to open source software. There’s always been an implicit value to being at the top of the pyramid – hence the prestige not always fairly attached to “the commit bit”.
- Old computer facts (storage sizes) presented in handy infographic form? Sign me up!
- vitunes, a curses-based playlist manager. OpenBSD-specific, but may work on DragonFly. I like the look. (via)
- Video4Linux support is being worked on for FreeBSD, as apparently the headers are available without having to accept the GPL. This makes it potentially available to all the BSDs, which is nice.
- FreeNAS is moving to Linux, which is a mistake bummer. Except iXsystems stepped in and now FreeNAS is continuing as a FreeBSD-based item. A story that seemed bad but came out well, thanks to iXsystems. (Quick, buy their hardware!)
- “If you know of surviving software on 1/2″ tape, paper tape, cards, DECtape, etc. from users groups or computer manufacturers, please contact us. Equipment is available to recover these bits, and in some cases can be brought on-site.” (via)
- 3 BSD-themed holiday gifts.
A number of recent changes will be important to you if you develop on DragonFly:
- Sascha Wildner has added a indent(1) profile that matches what is usually done in DragonFly.
- Also, there’s a dragonfly.el for emacs users.
- Now new, but worth mentioning again: there is an excellent development(7) man page.
- Alex Hornung has ported and modified FreeBSD’s minidumps, so crash dumps can now be kept smaller than your total physical memory size.
This has been around for a while, but I’m re-mentioning it because it’s not really linked anywhere: Simon ‘corecode’ Schubert has a version of the FreeBSD NVIDIA video driver that should work on DragonFly: http://gitweb.dragonflybsd.org/~corecode/nvidia.git. It should be possible to clone from that link, build the code, and use it. (Untested by me – if you’ve done it, some explicit instructions would be helpful to others.)
Alex Hornung has ported FreeBSD’s kbdmux, making it possible to run multiple keyboards. This can help if a system has a built-in virtual keyboard, as some newer HPs do.
Dear universe, including DragonFly people: stop doing so much stuff. It’s hard to keep up.
- Git in One Hour, an O’Reilly webcast. You need to register (free) and so on, but what the heck. O’Reilly doesn’t show crap.
- Poul Henning-Kamp is suing to recover the cost of Vista on his Lenovo laptop. (He’s installing FreeBSD.) I hope it comes out in his favor, though it will have little legal effect here in the U.S. (via)
- I didn’t realize this until I chimed in on the mailing lists, but one of the best books about file systems is freely available as a PDF.
- Another benefit of Hammer: you can’t run out of inodes, nor is it possible to have too many hardlinks.
- Some notes on pf usage in DragonFly. I know some parts have been mentioned before, but it’s good to sum up.
Dru Lavigne is going to be doing blogging/tweeting for the FreeBSD Project and FreeBSD Foundation. This is a good thing – BSD in general is helped by more of a conversation about what’s going on. I daresay this Digest has established that there’s definitely enough events, just with DragonFly, for daily news.
Also, Dru’s published summaries of the articles in the upcoming July ‘Collaboration’ issue of the Open Source Business Resource.
The newest BSDTalk has a conversation from BSDCan 2009 with 5 different FreeBSD core team members, for 38 minutes.
Mashing together to make one post:
These PC-BSD 7.1 vs. Kubuntu 9.04 Benchmarks are interesting but not that conclusive – different versions of gcc were used. (thanks J. Kanowitz) Here’s a different comparison of performance inside a VM from Ivan Voras.
This story popped up last year, focusing on Kip Macy’s legal issues. Kip is a BSD developer, contributing to FreeBSD and having worked on checkpoint support in DragonFly. Another side of his story has come to light. He and his wife could use the support, but there is (that I know of) no immediate way to help.
It would be nice if there was some common news source for BSD topics, instead of being an also-ran for Linux; this is an example of where an online community can support its own members, instead of that negative story that has been out for months.
Dmitry Komissaroff has posted a port of wlan, ath_hal and if_ath from FreeBSD. It’s not finished because he lacks the hardware. If you’ve got the hardware, the inclination, or both, please assist.
Freddie Cash has an interesting writeup of how he put together a very capable and cheap backup system using ZFS; this is part of a larger discussion on Hammer, ZFS, performance and solutions.
The FreeBSD Foundation is looking to give people money to work. (pdf) Specifically, they have USD $30K to give to people wanting to work on FreeBSD subsystems. Fight global recession!
‘Timofonic’ spotted this post by an NVIDIA employee describing the changes needed for better performance/support of NVIDIA chipsets in FreeBSD. This could apply to DragonFly., though I daresay these issues would already be fixed (or at least worked on) if it wasn’t a closed-source driver.
Of course, while I’m at it, I may as well wish for a pony and a million bucks, as there’s probably business reasons for the closed-source driver that are more compelling than the opinion of Some Guy with Blogging Software Installed.
