The default kernel config for DragonFly has changed: Sascha Wildner has added the acpi, gpio_acpi, gpio_intel, smbus and smbacp devices. If you are using a custom kernel, you’ll probably want to add these. If you aren’t using a custom kernel – you should have no negative effect.
The title really says it all – if you have a Coffee Lake series Intel chipset, your video is accelerated on DragonFly.
One side effect of Meltdown/Spectre are CPU microcode (firmware) updates. For future needs: sysutils/devcpu-data is the port that has the updates for Intel, and cpucontrol(8) is the program you run on DragonFly to add them.
I haven’t used this myself, yet, so I can’t tell you how necessary an immediate update could be – but you will probably want to use it soon.
Update: Newer CPUs might require this sizing change.
If you are running DragonFly-current, you can get your floppy drive running again. This is actually hard to test; floppy drives are becoming an endangered species.
I just wasted an hour trying to figure out why xorg had strange output but no errors on this laptop, and it’s because I had i915_load=”YES” in /boot/loader.conf instead of i915_load=”YES” in /etc/rc.conf. I’m almost nearly sure I’ve mentioned that before, but if not: here you go.
(though if you never plan to run X, you can put it in loader.conf and everything will just work.)
(Title updated for a more correct sentence)
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.
Update: accelerated X will need a different setup – see my later post.

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.
