i915 support moves forward again


Francois Tigeot has stepped i915 support in DragonFly even farther, this time bringing it to match Linux 3.17.  This may be most useful for those with Broadwell and Cherryview chipsets.

Many Hammer 1 updates, and credit


I don’t note it enough, but Tomohiro Kusumi has been making constant updates to HAMMER, the version we have now.  Often they are the sort of update that makes the code more readable, or fixes possible problems, and so on.  Very essential, but hard to post about it.  In any case, I’m using his recent improvements to hammer volume-del to note his contributions, of which there are much more than the day’s worth I link here.

A new regex test suite and library


Did you know that AT&T maintains a regex library and test suite?  I did not, but now DragonFly has both, in part for better multibyte character support.

(corrected to note that the regex library is not from AT&T – thanks, anonymous commenter)

More Radeon support work


Most of the news is about Intel video support, but Radeon direct rending improvements are coming too.  ‘zrj’ have brought up drm/radeon support to match what is in Linux 3.12.  Worth trying if you’ve had problems with your Radeon and audio, going by what I’ve seen people report in IRC.

Not the vi you expected


The vi in any BSD is not the original Berkeley vi – instead it’s usually nvi.  However, thanks to John Marino, DragonFly has the up-to-date, multibyte-supporting nvi2.  (I know I’ve made reference to the nv/nvi difference before.)

Resetting c720p touchscreens


If your DragonFly-running c720p (the touchscreen model) occasionally decides to go perma-bonkers, Matthew Dillon has added a method to reset it, either on reboot or by setting debug.atmel_mxt_reset=1.

DragonFly 4.2.4 released


There’s been a bugfix-release to the release version of DragonFly, bringing it to 4.2.4.  This is to fix a rare crash on issuing ‘shutdown -h now’.  If you haven’t had this problem, there’s no rush to upgrade.

Live nmbcluster adjustments


A DragonFly machine with a lot of network traffic will have a significant amount of memory consumed by all the running network connections.  (as with any system)  It’s now possible to adjust the amount of memory set aside for those operations, live.  This sort of fine-tuning will only matter if you run an extremely busy machine, but it’s worth it if you do.

Some recent updates: ACPICA, GCC, video


I’m globbing these DragonFly updates together in a single post because I’m running behind:

ACPICA was updated to Intel’s newest version: 20150717.

GCC in DragonFly was updated to the 5.2 release.

DragonFly DRM (that’s Direct Rendering) now supports ValleyView chipsets.

No more hostapd


hostapd, for creating a wireless access point, has been included in DragonFly along with wpa_supplicant, for a long time.  Like wpa_supplicant, there’s a version in dports that is the latest version and is easier to update (e.g. no system update required to get a newer version.)  Unlike wpa_supplicant, there’s no chicken-and-egg installation problem if it’s not in the base system – so out it goes.

Try that USB install again


If you’ve previously tried to install DragonFly using a USB thumb drive, and it would somehow not be found to boot from, there’s a potential fix.

Use wpa_supplicant only long enough to replace it


DragonFly ships with wpa_supplicant, for setting up WiFi.  However, there’s no guarantee it’s the latest version.  A solution exists: security/wpa_supplicant in dports.  However, this has a chicken-and-egg problem, where you need wpa_supplicant to get online and download the dports version of wpa_supplicant.  So, DragonFly still includes wpa_supplicant in the base system, but you should upgrade to the dports version when possible.

DragonFly libm changes


DragonFly now has the same math library (libm) as OpenBSD, replacing an earlier combined version of I think what NetBSD and FreeBSD ran.  This doesn’t necessarily directly affect you, but it’s work worth doing; matching the underlying frameworks between BSDs helps everyone.

Power statistics


Sepherosa Ziehau has been doing a lot of work with various processors states to save power on DragonFly.  He’s published a summary of how well the various P-state/C-state/mwait settings work.  He found that setting a lower C-state can perversely improve performance.

For those saying “but how do I set these lower power states?”:

sysctl machdep.mwait.CX.idle: AUTODEEP
sysctl machdep.cpu_idle_hlt: 1 (or higher)

DragonFly 4.2.3 released


There was a newer release of OpenSSL (1.0.1p) last week, so there’s a new revision of the DragonFly release – 4.2.3.  There’s little major change other than the security fix for OpenSSL.

Those readers who can count past 2 may notice that there wasn’t a 4.2.2.  We went straight from 4.2.1 to 4.2.3.   That’s my fault.  I screwed up tagging and Git doesn’t like repeated, deleted tags.

Chromebook c720 results


Some time ago, I acquired a Chromebook with the help of all you kind readers.  Here’s a mini-report on how DragonFly works as a desktop.

The hardware: what I have is an Acer c720 Chromebook.  The C720p is the touchscreen model, and is equally well-supported by DragonFly.  A larger-capacity M.2 SSD (which is relatively easy to install) is the only real need, as the installed one is only 16G.  It’s easy enough to see what the laptops look like; it’s nothing fancy but it’s suitably light.

The software: There’s a wide-ranging and complete install/tweak guide for the c720 and c720p on the DragonFly site.  Note that it goes down to the point of even changing the keymap for the special keys on the keyboard.

Things I don’t like:

  • The mousepad needs a physical click, not a tap, which decreases accuracy.
  • There’s only 2G of RAM, and not expandable.  You will notice this if you tend to open a lot of tabs when web browsing.
  • I’ve had mousepad trouble, but I’m the only one reporting it, so I think it’s just bad hardware luck on my part.

Things I do like:

  • pkg is a godsend, making installation and upgrades almost effortless.  I’ve gone binary-only so far.
  • Many things Just Work – for example, the xfce4 battery plugin.
  • xscreensaver works great; even the 3D modules.  I don’t know why it entertains me so.
  • I haven’t run the battery out to make sure, but it looks like it would last a few hours.  Suspend/hibernate are not supported, but low power modes are.
  • There’s a lot of multi-touch shortcuts built into the touchpad.

It’s an excellent BSD laptop, for light use, at low cost.  The next step up would be into Thinkpad territory, which raises the cost or increases the age – and may not be as consistently supported.

Stickers stickers stickers


Something I’ve wanted for a long time: DragonFly stickers.  Or ‘decals’, if you want to sound fancier.  Markus Pfeiffer has them set up on Stickermule.

I just created an account there, and apparently I can supply a referral link which gets you and me both a $10 credit, if you use that.  It’ll make you sign up, then you’ll probably have to go back in with the direct link for the DragonFly sticker.

Sascha Wildner has been removing the no-longer-needed bits of i386 support in DragonFly.  One of the things going away is APM, the 32-bit power management superseded by acpiconf.  If you still type ‘apm’ out of habit, it’s aliased so you won’t be surprised.

Console scaling options


Now that DragonFly can (in most cases) offer video outside of X with KMS, not just text, more console options are possible.   By default, your accelerated console will scale to 80×25, but you can now tell it how many columns you want and it’ll automatically scale to fit your resolution.  Or you can turn it off.

DragonFly 4.0.6 image up


I’ve uploaded DragonFly 4.0.6 ISO and .img files.  (Does that capitalization make sense?)  They should be available at your nearest mirror, or will be shortly. I am still working on the 4.2 release candidate images.

DragonFly 4.2 and 4.0.6 branched


The more eagle-eyed may have noticed a branching for DragonFly 4.2, and for DragonFly 4.0.6.  The 4.2 branch is currently only a release candidate, so don’t necessarily change over yet – it’s for testing, not release.  Note that packages for 4.2 are not yet built, so you’ll have to manually specify a package path to install with pkg on 4.2 – for now.. That won’t be the case for the actual release, of course.  DragonFly 4.3 users will have to specify PKG_PATH manually to use 4.2 images until new ones are built.  4.2 release candidate users will be fine.  (see comments for correction.)

The 4.0.6 release is mostly to get the recent OpenSSL update into a 4.0.x build.

I am working on image building for both.

Video memory defaults changed


The direct memory access reservation on DragonFly has been set to 128M.  It used to be 16, but anyone using a system for more than a text console would want the greater memory reservation.  It can be set back to 16M, which is useful probably if you are one of those text console users, or if you have a strangely underpowered video card.

Eventually everything goes SMP


Even sysctl accesses can be made to handle multiprocessor environments.  This can actually make a difference when you’ve got a lot of processors building a lot of software, as in all of dports.

Hammer 2 now uses LZ4 compression by default.  It also uses a new CRC algorithm that performs much better, and there’s numbers to prove it.  It helps iSCSI too.  When I say new, it appears to be from the 1980s?  I may be looking at the wrong place.

Shut up ARP


Sepherosa Ziehau has introduced a new sysctl:

net.link.ether.inet.log_arp_creation_failure

Set this to zero and you won’t get endless ARP events from networks you aren’t on.  For example, I’m hooked up to a cable modem.  I only get a public routable IP address, but the network used for the cable modem network itself bleeds ARP packets out where my DragonFly machine can see it.  Since it’s on a different network segment than the address I receive through DHCP, it always fails and the system logs it.  For example:

May 11 05:20:52 www kernel: arplookup 100.68.112.145 failed: host is not on local network

I can’t do much about it since that layer 2 leakiness is going to happen, but I can shut it up with this sysctl – and thank goodness, cause I’ve been seeing these messages since first using a DOCSIS modem in… 2001 or so?

Building only one compiler


DragonFly builds two compilers by default.  If you weren’t interesting in building both, there were switches to build only the default, like NO_GCC47.  This changed with every compiler update.

With the switch to GCC 5, the new switch is “NO_ALTCOMPILER”.  That will last through compiler changes.  I’m mentioning this now because sooner or later, you’ll want to gain back some time on a buildworld.

GCC 5 released, switched


DragonFly now has GCC 5.1 release.  If you are running DragonFly master (i.e. 4.1), you’ll probably want to both rebuild world and kernel, and update your packages so they all match.  There’s already packages built with GCC 5.1, so binary package upgrades can happen quickly.  There’s GCC 4.7 packages still available if you aren’t making the jump yet.

If you’re on DragonFly 4.0.x – nothing’s changed.

Changing to gcc 5.0


The default compiler in DragonFly is going to change over from GCC 4.7 to GCC 5.x very soon, to match the GCC 5.1 release.  This means that packages built for DragonFly-master won’t be compatible with the old ones.  You will need to reinstall packages when you next ‘pkg install’.  John Marino has an extensive writeup detailing what’s needed, and the actual change is some days off.

If you are using DragonFly 4.0.x (the release), this doesn’t affect you at all.
