led(4) for you and me


Sascha Wildner brought in led(4) from FreeBSD.  It’s a driver for flashing LEDs, as you might have guessed.  I’d like to see someone make Blinkenlights, whether BeBox-style or just generally mysterious.

Backlight on a laptop


Markus Pfeiffer has made it possible to control your laptop’s backlight using ACPI – if you have a i915 chipset and DragonFly.  xbacklight does not work, but setting hw.acpi.video.lcd0.brightness does.

Haswell graphics and port support


Thanks to Francois Tigeot, the drm/i915 driver now supports Haswell processors, and the special FDI and DDI ports they use.  I am late posting this.

Mach64 users needed


If you are using the ATI Mach64 drm driver on DragonFly, Francois Tigeot would like to know.  He’s done something that breaks it, but he’s making the educated guess that this more-than-10-years-old card is no longer in use.

Acer Chromebook c720p support


If you remember the earlier work to support DragonFly on An Acer c720 Chromebook, it’s been repeated for the c720p.  The “p” means it’s a touchscreen.

iwn trick: ifconfig wlan0 -ht


If you have a DragonFly system with an iwn wireless chipset, and you are having trouble connecting and running in the 5Ghz part of the spectrum only, here’s a tip: the -ht switch may fix it.

Haswell GPU support in DragonFly


There’s been good progress in Francois Tigeot’s work on Haswell graphics support in DragonFly.  If you have one of those newer units, you should be able to use the i915 driver with it now – as long as you keep acceleration off.  (You won’t notice any difference in 2D anyway.)

drm/i915 support update


If you have a i915 video chipset (which appears to be most every recent laptop), Francois Tigeot would like you to try his huge patch.  It doesn’t support Haswell chips yet, though it lays some of the groundwork for it.

Hammer and mirrored disks


A frequent question people ask when trying Hammer is “How can I do software RAID to cover a disk failure?”  Hammer provides for streaming one volume to another, so you can duplicate drives, but there isn’t an automatic failover mechanism as there is with a RAID setup.  The first answer is usually “get hardware RAID“; my preferred solution.   The remaining software solutions are vinum, ccd, and lvm for DragonFly.

A sound project for you


If you were looking for something to do, finishing Francois Tigeot’s sound update would help a lot of people.  He’s currently tied up with i915 support work.  The patches need device cloning to work with devfs, and midi removal.

More i915 updates


Francois Tigeot has been working on making i915 video support work better; with his latest update, it’s worth trying the Intel-specific driver instead of vesa if you have both the 915 chipset and are running X.

Heads up: changing mfi to mrsas


The mfi(4) driver has had some data corruption problems on “Thunderbird” series RAID controllers.  There’s a newer driver, mrsas(4), that replaces mfi(4) for these controllers and does not have these issues, but switching may mean new drive locations and therefore some work to get booting correctly again.  Sascha Wildner has an extensive writeup about what this entails, and how to switch now if you have that hardware (recommended).

DragonFly x256


DragonFly now supports running on up to 256 CPUs.  256 is the initial limit on the basic interrupt controller, and it can be extended further.  It’s been tested on 255 CPUs so far, since that’s the highest number of CPUs you can bring up in qemu.

Posted by     Categories: Device support, DragonFly     2 Comments

One more CPU on DragonFly


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.

Try installing DragonFly again


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.

mrsas(4) driver for LSI Thunderbolt added


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.

bwn(4) added


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.

Various USB drivers added


I’ve been away because of some home construction taking up time, but this has actually been happening for a while: plenty of USB device drivers have been getting ported in to work with the new USB4BSD stack.  My links for that are not comprehensive.

Some 10G results on DragonFly


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.

New USB on by default


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.

arcmsr(4) update


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.

Two AMD changes


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.

For Summer of Code: >63 CPUs


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.

New C-state possibilities


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.

Better ACPI C-State support


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.

Did I mention new USB?


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.

Intel video users, please note


xf86-video-intel-2.21.15 should now work on your DragonFly system.  I don’t see it in dports, yet, though.

ACPI update


There’s a new ACPI version in DragonFly, and Sascha Wildner wants you to update your BIOS, just to be sure.

The cheapest possible DragonFly


With everyone buying tablets lately, the low end of computers is getting pretty low-cost indeed.  Creating single-purpose computers is possible, and I was thinking of doing that to create a Go-testing system.  (Though probably not necessary for me.)  It got me to thinking, though…

How low-cost a system could run DragonFly?  The master-slave and low system requirements of Hammer lead to some interesting possibilities.  There’s no Arduino equivalent for DragonFly because there’s no DragonFly on ARM, despite all my wishing.  DragonFly has been run on Soekris systems before, and might work on a PCEngines ALIX board.  Ebay, my basement, or Craigslist are options too, but not as fun.  Who has suggestions?

ACPI updates and power states


ACPI has been updated in DragonFly by Sepherosa Ziehau, to potentially support the very low-power sleep states available with Haswell CPUs.

Note: Sepherosa clarified that the lower power states are not available – yet.

DragonFly on a Chromebook c720


Matthew Dillon acquired one of the Acer c720 Chromebooks recently.  There were changes needed for the boot process, for the keyboard, an update from FreeBSD for the ath(4) wireless (g), smbus, and trackpad… but it works now, and he detailed exactly how to get it running, and even upgrade the drive.

RTL8191SE support


‘M M’ had trouble with his “Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC” on DragonFly some time ago.  He was able to get it working, and he documented the somewhat convoluted procedure here.

ixgbe(4) updated


The ixgbe(4) driver, for a number of Intel 10Gb network cards, has been updated by Sepherosa Ziehau to version 2.5.15.  Note that this changes the interface name to ‘ix’ by default.  This driver is actually written by Intel.

DragonFly in KVM


If you’re planning to run DragonFly in KVM, remember this post from Matthew Dillon, giving the settings he uses.  This will save you a bit of time.

Good news for iwn(4) users


If you have a recent laptop with an iwn(4) wireless chipset, Matthew Dillon’s recent work getting an updated version of the driver together will probably help you.  It was done specifically to support a Intel Centrino Wireless-N 2230, but many more should also now work.

A bunch of network hardware changes


I’m just going to roll all these updates from Sepherosa Ziehau together into one post, because it’s a lot:  He’s updated igb(4) to 2.3.10, updated em(4) to 7.3.8, merged the hardware abstraction layer of those two drivers, enabled TSO on all PCI-E em(4) chipsets, and added support for a whole slew of Realtek chipsets in the re(4) driver.  Whew!

tpm(4) module added


The tpm(4) driver has been added by Sascha Wildner, ported from FreeBSD.  What’s it do?

From the man page: “The tpm driver provides support for various trusted platform modules (TPM) that can store cryptographic keys.” Crypto keys stored in hardware, where they are in theory unmangleable, instead of on the disk. At least, that’s my impression after 30 seconds of research.
