If you are near Knoxville, Tennessee, PacBSD developer Adam Jimerson is presenting on package manager porting to the KnoxBUG user group tomorrow night.

BSDNow 212: The Solaris Eclipse
BSDNow episode 212 is out and I’m going to link it especially because I’ve been at work instead of posting like normal. Not surprisingly, it talks about the demise of Solaris and about vBSDCon and (links to videos from) BSDCan.
Blind at a BUG
Brandon Werner, will be talking at the SEMIBUG meeting tomorrow night at 7 PM. He programs for a living and is blind, so it should be interesting even just to see his preferred tools.
(Mentioned previously for In Other BSDs but I want to make sure people catch this.)

Not sure why, but there’s been a lot of BSD news the past few weeks. I am OK with that.
Late addition: NetBSD’s New York build cluster will be offline beginning Monday for about two weeks, which means no daily NetBSD or pkgsrc builds.

BSDNow 211: It’s HAMMER2 Time!
BSDNow episode 211 is up – you can guess at least one of the topics, I’m sure. There’s also an interview of FreeBSD Foundation co-ops – which is neat, because I didn’t realize the Foundation had co-ops.
Booting, UEFI, and text consoles
I installed a DragonFly snapshot on a Lenovo x220 last night. I went for a EFI install, even though the x220 has a “Legacy” option. When I booted, it looked like this:
It successfully booted, but once it hit the kernel load, it started printing to the top of the screen in that lovely repeating pattern you see.
Matthew Dillon helpfully pointed out that the DRM and i915 modules needed to be loaded. Hitting ‘9’ during the bootloader countdown got me to a prompt where I could type:
drm_load="YES" i915_load="YES"' kern.kms_console=1 menu
Which brought me back to the boot menu, but this time it loaded those additional modules to support the Intel video chipset – and it worked!
These lines can go in /boot/loader.conf for permanent use.
More ipfw work
In addition to the already-mentioned ipfw per-CPU state tracking, Sepherosa Ziehau has added per-CPU state tables to ipfw, and his commit documents the improvement in performance/latency. He’s also added ipfw support to sshlockout(8).
HAMMER2 in the installer
HAMMER2 is now available by default in DragonFly, and can be used in the installation process. (It was possible, but manual, before.) The next DragonFly release should be soon.

Kabylake NUC and DragonFly
Matthew Dillon’s been using a Kabylake NUC for a DragonFly workstation and it’s generally working out well. It’s tiny enough to lose on a desk, in my opinion. He added performance details and a screenshot. The Specific Configs page has his notes, recorded, too.
Related laptop tip: If you have a Lenovo Yoga and can’t mount the drive after install, various sdhci modules may be the answer. Update: definitely the answer.
BSDNow 210: Your Questions, part 1
BSDNow 210 turns the tables and interviews the moderators, along with the normal news summary.
ipfw improvements
Sepherosa Ziehau has made some improvements to ipfw in DragonFly, moving it to per-CPU state tracking among other things. (I haven’t mentioned just ipfw in foreeeever.)
His commit message describes the improvements. Of most interest: it reduces the performance impact of running ipfw in his tests to almost nothing. Does this translate to ipfw on other BSDs? I don’t know.
New system: Ravenports
John Marino has assembled a new packaging and building system. It’s called Ravenports, and he wrote a short intro, and has a filled-out site to go look at.
This is big news, in part because he knows what he’s doing (John worked on dports and created synth) and because it’s cross-platform. The prior work on synth is part of the reason DragonFly works so well under pressure – the “build everything as fast as possible as complete as possible” strategy makes a great stress test.
There’s no need to change software management strategies yet. It can be used at the same time as dports, so it doesn’t necessarily change anything for the next DragonFly release.
DragonFly at EuroBSDCon 2017
Francois Tigeot is going to be giving a talk about the DragonFly graphics stack at EuroBSDCon 2017. (14:00 September 21st in Paris) Registration is already closed because I didn’t realize how soon it was happening – sorry!
