The latest quarterly release of pkgsrc, 2010Q4, is out. I’m working on the build of binary packages… It’ll be some days.
Venkatesh Srinivas wrote out a long description of what he’s doing with the removal of the Giant Lock from tmpfs. I’m pasting it here verbatim, for your enjoyment.
Yeah, so those Phoronix benchmarks are crap, but Matthew Dillon went and implemented some things that would speed up Hammer write performance in any case. Read his summary for details.
The default Hammer version in DragonFly is now version 5, which is the one that includes deduplication. Enjoy, bleeding-edge users! Otherwise, wait for the next release.
Version 6 is there, but don’t upgrade to it yet; there aren’t significant user-visible changes, and the usual disclaimers for new versions apply.
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.
Sascha Wildner re-added burncd(8); it still works for some people. As Matthew Dillon pointed out, cdrecord is probably the better long-term bet.
Avalon, the machine that works as the master mirror site for DragonFly, and also as git.dragonflybsd.org, is being moved. Binary package downloads and source updates won’t work in the meantime. If you can’t wait for the system to come back, change the settings for pkg_radd or in /usr/Makefile to point at a different host.
Sascha Wildner continues the driver update streak, bringing in the updated FreeBSD version of the aac(4) driver. This adds support for 40+ Adaptec AdvancedRAID cards – the aac(4) man page has a very long list.
The burncd command has been removed; it hasn’t been working for some time. The sysutils/cdrtools utility cdrecord is the viable alternative. cdrecord is a pkgsrc application, but it comes on the DragonFly install CD/DVD/image/whatnot.
Ilya Dryomov wrote out some more details about his deduplication work, with some notes on what he plans next for this feature.
Apparently the surplus money from the recent NYCBSDCon is going to each of the BSD projects. Great news! Now, what to do with it…
Ilya Dryomov has added live deduplication, or as he titles it, “efficient cp”. It’s experimental and turned on with a sysctl, so approach with caution.
Here’s a nice collection of post-installation notes on DragonFly. They’re part of a larger UNIX note collection. I may have linked to it before; I don’t remember. This note’s new, though.
Xerox Network Services is gone from DragonFly. Does anyone, anywhere, use this protocol? Ironically, I don’t recall this even being visible on the Xerox hardware products I have at work.
Tim Bisson put together support for the RealTek 8168E network card, under the re(4) driver. It’s in DragonFly now.
Another bus bites the dust: EISA is no more on DragonFly. I don’t know if there’s even any system that DragonFly could boot on and would use this. Still, remove your hats and enjoy a moment of silence.
Apparently there’s a lot of DragonFly people going to the 27th Chaos Communication Congress. Of course, I don’t know if there’s any tickets left at this point.
