Justin Sherrill – Page 80 – DragonFly BSD Digest

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.

Reminder: finding sound on DragonFly

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.

tty_token refactoring in DragonFly

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.

Virtual DragonFly: memory balloon

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.
