The max number of CPUs on DragonFly just went from 63 to 64. This is really just a side effect of preparation to move up that limit, but I am entertained by the single-digit bump.
Did you try to install DragonFly relatively recently and it never made it past the bootloader? Apparently there’s a bug in some BIOS when using a smaller USB drive to install. The loader checks multiple places for information, and if it checks somewhere that’s ‘farther’ than the end of the disk (i.e. 6G on a 4G USB key), the machine locks up.
Matthew Dillon and Kyle Davis spent a good number of hours figuring this out today, and Matt committed a fix. So, if you were bit by this problem, try a -LATEST image about 24 hours from now and see if it works.
Sascha Wildner has added the mrsas(4) driver, which works on a variety of LSI Thunderbolt devices – a variety of RAID cards, names for which are listed in the commit message. Note that as of right now, these devices by default get taken by the mfi(4) driver, so you need to take extra steps to get mrsas(4) used.
If you have DragonFly on a laptop, and a docking station for that laptop, it may be better supported now. (no, I don’t know exactly what acpi_dock does.)
Alexandre Perrin contributed an upgrade of wpa_supplicant and hostapd for DragonFly, bringing it from 0.6.10 to version 2.1 – a 4-year jump.
A relatively calm week – probably because there were many people at BSDCan.
- DiscoverBSD’s summary for 2014/05/19.
- Undeadly has a summary post linking to all the OpenBSD presentations at BSDCan.
- OpenBSD and the little Mauritian contributor. Hey, Loganaden was in the DragonFly GSoC… 3 years ago? It blurs together.
- Julio Merino’s trip to BSDCan 2014 and his thoughts on Jenkins and Kyua after. I completely agree with what he says about BSD conventions: being around so many other people all excited about the same topic really energizes you.
- CoovaChilli on FreeBSD.
- NetBSD has support for the HYT-221/271/939 humidity/temperature I2C sensor.
- Hey, that was nice of Mediatek to provide a free license for rum(4) in OpenBSD.
- The EuroBSDCon papers deadline is extended a bit.
- You can now see what your battery is supposed to have for capacity on OpenBSD.
- Apache 1.3 and 2.0 are already depreciated and probably coming out of pkgsrc.
- FreeBSD gains a driver for the Intel 40G Ethernet Controller XL710. There’s a long discussion on the list about the nonstandard i40evf name breaking things.
- FreeBSD has sendmail 8.14.9.
- FreeBSD has gained CUSE support. I can read what it does but don’t know where it’s used.
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.
