Sascha Wildner is continuing his huge driver-adding streak, this time with tws(4). It’s a port of the FreeBSD driver, for “LSI 3ware 9750 series SATA/SAS RAID controllers”. The commit message has a list of individual models, and further credits.
(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.
