Some other BSDs


For once, I got to read the commit logs for other BSDs…

The OpenBSD ‘Papers’ page has some videos listed to match the OpenBSD-related presentations from EuroBSDCon 2012.

Not only does NetBSD support the BeagleBoard, but Michael Lorenz is committing from it.

FreeBSD has brought in a new version of bmake and jemalloc.  I’ve seen a number of other commits recently attributed to ‘NetApp’, which is good to see.  Also, preliminary USB support for boot loaders.

PC-BSD is looking to use pkgng, the same binary package manager used in John Marino’s DPorts.  It’s proving quite popular.

Virtio and virtio-block drivers added


Venkatesh Srinivas and Tim Bisson have been working for some time on a port of FreeBSD’s virtio and virtio-block drivers.  (see man page commit)  They’ve now been committed.  This should make your virtual disk perform better, if nothing else.

Lazy reading for 2012/12/30


The last of the year.

Your unrelated comics link of the week: Marlo Meekins’ Tumblr.   Her lettering is refreshingly expressive.  That may sounds strange to single out, but so many people place words as an set block of text rather than as part of a graphic layout.

Crypto card possibilities


This discussion of cryptographic hardware for FreeBSD may include hardware that would work for DragonFly too.  Can someone verify?

More HighPoint support


Sascha Wildner recently brought in support from FreeBSD for HighPoint’s RocketRAID 4520 and 4522 SAS/SATA RAID cards.  It’s in the hptiop(4) driver.

SMBIOS access now possible


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.

Clang-Day today for FreeBSD


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.)

From make to bmake


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?)

Major USB update arrives


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, RSS, and SMPng


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.)

Some more books to read


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.

NYCBUG, Adrian Chadd, and teeny tiny computers


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.

Is your battery smart?


Sascha Wildner has pushed smart battery support, based on a patch from Dmitry Komissaroff and FreeBSD.  He asks people to try it out.  It apparently provides for more accurate battery charge level readings?

More find(1) options


Sascha Wildner has synced find(1) with what’s in FreeBSD, which means there’s a lot more options available – see the commit for details.  Many of them are for GNU compatibility, and I’m sure I’ll forget them all.  I seem to have issues remembering how to use find(1) successfully.

New tool: netblast


Sepherosa Ziehau has added netblast, a tool originally from FreeBSD that, if I’m reading the commit right, flings packets of a given size at an IP/port of your choosing, for as long as you want.

Recent syncs from FreeBSD and back again


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.

pgrep, pkill, and jails


It’s now possible to specify a jail ID when using pgrep and pkill(1), to capture processes specific to a jail.  It’s similar to the same option in FreeBSD, except no compatibility issues since this option did not previously exist in DragonFly.

WHMCS installation notes


Michael Lucas installed WHMCS, a commerical hosting management tool, on FreeBSD.  He tells a story of doing so, and in the process happened to list all the PHP modules needed for it to run.  I’m linking it because that list is going to come in useful for someone, someday.

mps(4) updated


Sascha Wildner has brought in improvements to the mps(4)driver from FreeBSD.   It’s for LSI Logic Fusion-MPT 2 SAS controllers, and apparently didn’t work very well… until now.  Sascha’s commit message details what’s new, including RAID support that is not yet mentioned in the man page.

Starve reads or starve writes?


Remember the benchmark tests I linked a few days ago?  There’s been ongoing discussion about them, and a recent comment from Matthew Dillon sums it up pretty well: the benchmarks differ depending on whether you favor reads, or favor writes.

Blogbench and Areca RAID tests


Francois Tigeot tested a system under both FreeBSD and DragonFly using various RAID setups with arcmsr(4) and blogbench.   Hooray for graphs!  Like any good benchmark, it quickly went to discussion of how the test was conducted and how the various runs differ.  (Follow the thread.)

BSD Magazine: ZFS


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.

sh updates


Peter Avalos went looking for updates to /bin/sh, and found a lot of them, including regression tests.  Even though sh is…  15 years old?  Older?  It dates back to BSD 4.4 and before – anyway, it’s been around forever, but there’s still things to do with it.

tws(4) added


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.

KMS and GEM work, for cash


There’s still no support for KMS/GEM on any most BSDs, though there are people interested in it for FreeBSD.  One of DragonFly’s Summer of Code projects was just that, though it’s not in a state where it can be really used.

Another BSD?


Scott Ullrich, who has worked on several BSD-related projects, including DragonFly, has something called vCloudBSD, about which you now know as much as me.  It looks to be a FreeBSD auto-installer for virtualization, though I’m sure I’m overgeneralizing.

psm(4) update


Antonio Huete updated psm(4) using code from FreeBSD; I don’t think it’s been committed yet but the patch is available.  This will be especially valuable to you if you have a synaptics touchpad; it enables many of the functions.

More development tools


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.

Using NVIDIA on DragonFly


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.)

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.

Help the Macys


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.
