Oddball and quirky links, the best part of Lazy Reading.
Your unrelated music link of the week: Justin Broadrick interview.
It’s a mad rush to get these all posted in time for the weekend.
I should have mentioned this before, but: here’s how to use the virtio balloon memory driver in DragonFly, which is timely because it’s now in base.
There’s a fix for memory contention in NUMA (meaning Threadripper in this case) configurations on DragonFly; the commit has before-and-after numbers. They are somewhat context-free, so I can’t easily translate to what this means for performance.
BSDNow 269, along with convention reports and other items, covers something I never expected: System V daemons on BSD.
I like to repeat this from time to time: loading the appropriate sound driver on DragonFly consists of loading all the sound kernel modules and seeing which one sticks, in dmesg . Chances are good it’s snd_hda anyway.
The performance page on dragonflybsd.org has been updated with numbers on symmetric multiprocessing performance. (Scroll to the 2018 section.)
Well, I cleared my tab backlog, but not my RSS backlog…
If you were looking to install DragonFly into part of your already-in-use hard drive, here’s some conversation about the process.
This week’s BSDNow has a lot of “You will not regret knowing this” material – ZFS performance measurement, 2FA SSH, and using Netcat in various ways.
Matthew Dillon’s moved tty_token from a global to per-CPU token in most cases in DragonFly. This is good for performance as with any global->local shift, but I can’t tell you what aspect it improves.
Did you use the digi(4), rp(4) and si(4) serial device drivers in DragonFly? I don’t think so, but you definitely can’t now.
SemiBUG is having the monthly meeting tonight. The presenter is Nick Holland, talking about SPECTRE mitigations in OpenBSD, and similar mechanisms. If you are near, go.
If you are running DragonFly in a virtual environment, ‘ddegroot’ has put together a virtio_balloon driver for handling memory usage. (An explanation of the term) Try it if you can; he wants testers.
Here’s your reminder: MeetBSD is happening October 19-20 in Santa Clara, CA. That’s the end of this week. Go, if you are near.
A good, oddball week.
Your unrelated comics link of the week: Draculagate, a book funded by Kickstarter. Watch the video.
Still playing catchup with links.
In case it’s useful to you, here’s several laptop recommendations for DragonFly.
BSDNow 267 is posted a bit early this week, with an interview of Michael W. Lucas, about his upcoming Absolute FreeBSD 3rd edition and local BUG.
