Sascha Wildner has updated ral(4) with support for RT2700/2800/3090 chipsets. If you have one of these, please try it out – these are untested.
Matthew Dillon brought in Adrian Chadd’s sleep state changes for the ath(4) driver from FreeBSD to DragonFly; you may see reduced power usage if you have the appropriate hardware.
If you’re using DragonFly in qemu, virtualbox, whatever – but not VMWare – there’s a new virtio-net driver to try out.
You know what always makes me happy? When someone shows up out of the blue and says “Here; I did this cause I needed it; everyone can share.” The latest example of that is Imre Vadasz porting bwn(4), for the Broadcom BCM43xx wireless chipset over from FreeBSD to DragonFly.
In a thread about video cards on DragonFly, Francois Tigeot listed good ATI cards to try, and pointed out the VESA driver is probably your best bet right now with NVidia cards.
The acpi_thinkpad module (section? code?) has been updated. Update if you are on DragonFly 3.7, or be patient if you are on 3.6.
In part because I asked him, Sepherosa Ziehau benchmarked 10G ix(4) with 2 ports on DragonFly. The results? Good, both for bandwidth and for CPU usage.
DragonFly has moved from the old USB stack to USB4BSD by default. That means:
- If you are already using USB4BSD, you will want to remove WANT_USB4BSD from your kernel config.
- If you have trouble, switch back to the old USB.
- There’s some drivers that are not yet converted; help with them would be appreciated.
- A full kernel/world build and ‘make upgrade’ will be needed in either case.
Sascha Wildner’s announcement email has all the gory details, including the kernel config changes to move back to the old USB setup. This is of course in master; 3.6 users are unaffected.
Sascha Wildner has updated arcmsr(4), which brings in support for the Areca ARC1214, ARC1224, ARC1264, ARC1284, and ARC1883 models, from FreeBSD. Please test if you have the appropriate hardware.
Coretemp is now in the default kernel configs for DragonFly, so you can use coretemp to see your Intel CPU temperature.
If you’re using the i915 driver for xorg, and xorg dies with a “No monitor specified for screen” error, there’s a config change to fix that, or you can just update.
If you have i915 chipset-based video on DragonFly, and you get a “Output xxx has no Monitor section” complaint in your xorg logs, look at this fix using xrandr.
Here’s two recent changes in DragonFly that may interest you if you have an AMD processor: Compute Units are now supported, thanks to Mihai Carabas, and Imre Vadasz ported over km(4), for temperature monitoring on 14h and 15h CPUs. I’m still not totally clear on what Compute Units are.
Here’s a potential DragonFly and Summer of Code project: adding support for more than 63 cores to DragonFly. Matthew Dillon has already outlined how.
It’s now possible to reach deeper power-saving C-states with DragonFly, thanks to work from Sepherosa Ziehau. It’s possible to have it auto-adjusted by setting two sysctls.
If you have an Intel-based system, and are running DragonFly master, there’s new c-states (power-saving modes) for you to try. Sepherosa Ziehau posted a note about testing and feedback.
There’s been periodic commits updating the USB4BSD support in DragonFly; I haven’t been linking to them because they are generally incremental. However, it’s good to (re?)mention just how you can build DragonFly with that new USB support.
xf86-video-intel-2.21.15 should now work on your DragonFly system. I don’t see it in dports, yet, though.
There’s a new ACPI version in DragonFly, and Sascha Wildner wants you to update your BIOS, just to be sure.
