Do you have a wpi(4) or iwi(4) device?


If you have an ath(4), wpi(4) or iwi(4) wireless network link, and you’re running DragonFly-master, please update.  Sepherosa Ziehau has pushed Johannes Hoffman’s wlan_serialize branch, which means bringing up wlan0 is a bit easier – and less crashy.

It needs to be tested for wpi(4) and iwi(4), however, so if you have success or failure with those devices, please say so in reply.

(new post category starting now: “Please test”)

Multiple ring support on Broadcom 5709/5716


It seems Sepherosa Ziehau won’t rest until he’s reached peak performance for every network card in DragonFly; he’s added multiple ring/MSI-X support for Broadcom 5709/5716 chipsets in DragonFly.  In more concrete terms, this means better speeds when transmitting and receiving multiple streams of data.

(at least, I think so.)

Software RAID options


Following this recent thread, it looks like the best answer for software RAID is: buy hardware.  I’d be interested to hear what people have experience with in the realm of cheap but OK RAID hardware.

Multiple TX queue support for emx(4), sort of


The emx(4) driver now has support for multiple TX queues, but it’s not on by default.  There’s scenarios where multiple queues work out with that hardware, but you have to be sure you are actually in the right setup for that first.  Check Sepherosa Ziehau’s commit message for the details.

Intel network chipset improvements


Sepherosa Ziehau has merged the hardware abstraction layer (HAL) for em(4) and igb(4), along with updating em(4)/emx(4) to version 7.3.4 and igb(4) to version 2.3.7.

Multiple transmit queue work results


Sepherosa Ziehau has posted a detailed message showing the speeds he gets with multiple transmission queues, using igb(4).  The short version:

Quick summary, the multiple TX queue support gives me:
+200Kpps for 2 bidirectional normal IP forwarding (now 4.40Mpps)
+160Kpps for 2 bidirectional fast IP forwarding (now 5.23Mpps)

Network fairness changes and what they mean


Sepherosa Ziehau makes commits almost daily to DragonFly’s network infrastructure, but I have a hard time quantifying it into Digest posts in part because it’s often very technical.  His most recent commits come with an explanation, however.  He has done plenty of work to improve overall transmission speeds in DragonFly, and now he’s working on ‘fairness’.  Fair, in this case, means ensuring that packet transmitting and receiving happen without either one monopolizing the connection.  In real world terms, this translates to much more constant speeds.  His recent commit details what he’s doing and some numbers to prove it.

Remember I said he’s improved speeds?  Note that in his example, he’s reaching stable peaks of 981 Mbps.  This is on a line that I assume theoretically maxes out at 1000.

HAMMER best practices, and RAID


Dave Hayes asked for some “best practices” ideas for setting up a HAMMER (1) system.  I replied, and the conversation turned to RAID, as these often do.  If you’re thinking of purchasing disk hardware in the near future, this will be useful to you.

Virtio and virtio-block drivers added


Venkatesh Srinivas and Tim Bisson have been working for some time on a port of FreeBSD’s virtio and virtio-block drivers.  (see man page commit)  They’ve now been committed.  This should make your virtual disk perform better, if nothing else.

AVX support added to DragonFly


Adam Sakareassen submitted a patch for AVX support for 64-bit DragonFly, and Alex Hornung has committed it.  If you’re like me and have only the vaguest idea what AVX is, it’s a set of processor instructions added by Intel to Sandy Bridge and later CPUs.

IFQ packet staging mechanism added


I’m not sure what IFQ stands for, but Sepherosa Ziehau’s added it.  It appears to be based on an idea from Luigi Rizzo called ‘netmap‘.  In this case, network packets are grouped together before being placed onto the network interface’s hardware queue.  That means better packet per second performance without a corresponding increase in CPU usage, as Sepherosa Ziehau’s report lists, along with needed sysctls.

IP Forwarding Performance


Sepherosa Ziehau has been making a lot of commits to increase packet-per-second rates without increasing CPU usage.  He’s published a sort of progress report/benchmark to show current performance levels.  It sounds like he’s expecting even better performance in the future, though I’m not sure how much more he could push out of it, since the bulk performance appears to be close to the rated capacity of the copper…

Still using ISA cards? A few more drivers removed


The stl(4), bt(4), aic(4), and cy(4) drivers are now PCI-only, which means no COMPAT_OLDISA kernel option, and a time to upgrade your hardware if you’re actually using these devices.  Does anyone even still have ISA slots?

More HighPoint support


Sascha Wildner recently brought in support from FreeBSD for HighPoint’s RocketRAID 4520 and 4522 SAS/SATA RAID cards.  It’s in the hptiop(4) driver.

SMBIOS access now possible


Sascha Wildner has added system management BIOS (SMBIOS) support, visible with kenv, from FreeBSD.  Use it for getting things like the BIOS revision, system manufacturer, and so on.  For example:

smbios.bios.reldate="12/04/2006"
smbios.bios.vendor="Dell Inc. "
smbios.bios.version="2.1.0 "

This may seem minor, but this can be very helpful when dealing with hardware you aren’t physically able to access.

MSI-X for the masses


Sepherosa Ziehau is switching a number of network cards over to use ifpoll, which means they will have capabilities similar to MSI-X, even if the network card doesn’t support it.  My suspicion is that it will make these cards perform better in busy situation where they would otherwise get bogged down… but that’s based on hunch rather than empirical testing.  As Sepherosa Ziehau pointed out, it certainly can’t hurt.

Major USB update arrives


Sascha Wildner has committed Markus Pfeiffer’s port of USB4BSD to DragonFly.   USB network, input , audio, and storage devices (including xhci/USB3 items) may work, though there’s no guarantee for each driver.  This is added but not on by default, so see the first link for instructions on how to rebuild your kernel to use it.  This will be in (but not default) the DragonFly 3.2 release.

(This is shaping up to be a much bigger release than I anticipated!)

Notes on smartmontools


Smartmontools will catch impending disk failures about 2/3 of the time, so it’s useful to run it and interpret the results.  The results can be somewhat complex, though.  However, it can be useful to look at other people talking about the output and glean knowledge from the context.

Do you have an ixbge(4)?


If you are using an Intel 10G Ethernet card with a 82598GB chipset, you’re using ixgbe(4).  You may want to set the net.inet.tcp.sosend_agglim sysctl to a value over 12 in certain circumstances, as described by Francois Tigeot.

Vendor support is always nice


I noticed that this recent commit from Sepherosa Ziehau is a bug fix for jme(4).  The commit thanks a JMicron employee for help.  It’s always appreciated when a vendor is helpful to an open-source project for hardware support.  It’s also something you should consider the next time you are shopping for computer parts.

Another SSD conversation


Pierre Abbat is curious about using Hammer on an SSD.  The discussion that came from that has some useful points, including notes that a straightforward SSD as disk works for most anything with Hammer other than very intensive database use, due to the history retention.  If space is an issue, swapcache on the SSD and attaching a normal HDD is a fine alternative.  A SSD with Hammer can leave some features off, though I’d argue that dedup is totally worth is.  Also, SSD speed is directly correlated with size.

Sascha Wildner’s added support (from FreeBSD) for the HighPoint RocketRAID 17xx, 22xx, 23xx and 25xx, via the hptrr(4) driver.

TCP Segmentation Offloading added


Sepherosa Ziehau’s added TSO support (that’s TCP Segmentation Offloading”, or “Large Segment Offload” going by Wikipedia) within IPv4 on DragonFly, pushing segmentation work from the CPU to the network card.  There’s also some DragonFly-specific improvements.

There’s been a lot of commits from him lately focused around network card improvements; they haven’t been easily summarizable, but it’s worth watching if you are interested in high-bandwidth usage and the hardware to support it.

A note for Atom CPU users


Not all flavors of Atom CPU support frequency scaling, as Sven Gaerner found out.  This means more heat and more power usage.  There’s further details scattered through the thread, but Sascha Wildner found what seems to be the definitive answer of which variants do and do not.

Hardware reports given out


New company Gainframe is offering up OpenBSD dmesg/pcidump/usbdevs output for every system they build.  I was originally going to link to this in a Lazy Reading entry, but then I realized it’s also a new company specializing in BSD-compatible hardware.   Read the interview; I met Michael Dexter at the last NYCBSDCon and he is a decent guy.

We need more of this sort of specifically targeted work.   Sites that rely on crowd-sourced contribution are good, but it’s not necessarily comprehensive, and you need a very large crowd for it to work.

Fixing X video performance


I’ve seen a few people complain about poor video performance in DragonFly, in Xorg.  If you see a bunch of  “contigmalloc_map: failed …” errors in your dmesg, your video card needs more contiguous memory allocated.  Set vm.dma_reserved to 32M in /boot/loader.conf and you should be set.  If that doesn’t work, try 64M.

DragonFly and a Mac


Carsten Mattner wrote out his notes on EFI booting on a Mac.  This gets you closer to booting DragonFly on there, but I don’t think it is completely working yet.

All that work, vindicated


Notice how the 2.12 release never really happened, and 3.0 came out about 6 months later than usual?  A lot of that delay was caused by a vigorous search for a weird bug.  Multi-threaded buildworlds would crash, seemingly randomly and rarely.  It turns out we have confirmation from AMD that it is, indeed, a CPU hardware bug.

How low can you go, with RAM?


Is it possible to boot with only 48M of RAM in a DragonFly system?  Probably not.  128M would be better.  I usually talk about the lower memory limit for Hammer, since it’s so relatively low for a snapshotting file system, but the converse applies here.  128M is probably the comfortable lower limit, though it’s pretty hard to find a system that would limit you that way without doing it on purpose.  128M sticks of RAM are practically disposable these days, really.

Odd DVD drive issue


Edward Berger found that using a LG/Hitachi DVD drive kept him from successfully booting a DragonFly install CD.  Using other manufacturers worked out fine.  What causes the problem?  I don’t know, but it’s worth mentioning it out loud in case someone else gets bit by it.

Setting up a DragonFly wireless access point

Better MSI support


That’s Managed System Interrupts, for when your hardware is passing a lot of data and generating a lot of corresponding hardware interrupts.  MSI is what deals with all that traffic.  High-bandwidth (10G) network cards, for instance.  Anyway, Sepherosa Ziehau’s made more commits than what I’m linking to here, for support with various devices.

There’s many other MSIs out there, oddly enough.

New ECC device


Sepherosa Ziehau has added updated the ‘ecc’ device, for Intel E3-1200 series systems.  What’s it do?  It will report on memory errors, and potentially fix them.

You should have ECC memory in your server already.  If not, you oughta.

Update: as Sascha Wildner pointed out, ecc(4) already existed, but didn’t support Intel controllers.  Also, the Xeon X3400 series is supported now too.

Remember rcrun?


I think a lot of people don’t realize rcrun exists, and run files in /etc/rc.d directly.  If you’re one of those people, read the rcrun(8) manpage.  Then, notice that Sascha Wildner has extended rcrun to work with the etc/rc.d in /usr/local and /usr/pkg too.

Video and USB fix


Matthew Dillon has written a contiguous memory mapper, which is designed to fix problems with video cards and USB drives that need a big chunk of memory to keep.  This can affect booting or later on, when disconnecting/reconnecting a USB drive.  If this still doesn’t fix the problem for you, try adjusting the sysctl ‘vm.dma_reserved’ to something bigger, like 64M.  It defaults to 16M.

That would be a recent ATI card, though I don’t know exactly which model name.  Samuel Greear has imported David Shao’s DRM work, originally for Summer of Code, last year.  Most newer Radeons should work (?).

MMC/SD cards now automatically supported


I did not realize this, but MMC/SD cards are not supported in the default DragonFly kernel.  Or at least, they weren’t until now.  (also committed to 2.12)

Update: PCI-based MMC/SD readers, specifically.  USB ones were already recognized as umass devices.
