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.

Go APE for bge and bnx


The bnx(4) and bge(4) network drivers now have APE support, thanks to Sepherosa Ziehau.  What’s that mean?  Other than an opportunity for punning jokes, I don’t know.

ISA support is really gone


ISA device support is really gone.  Well, except for keyboard and some spots where it can’t be be removed.  I don’t think I’ve even seen an ISA card in some years…

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.

Multiple TX queue support for mxge(4)


Multiple transmission queues are possible for the mxge(4) driver; I’m mentioning it because Sepherosa Ziehau’s post about this describes the exact tunables to configure this.

Clock explanations


Chris Turner was curious about clock skew when running under a VM, and Sepherosa Ziehau very kindly explained the different types of internal clock for DragonFly, and how to control them – a topic I’ve never understood deeply.

Multiple queues support for GigE


I stole Sepherosa Ziehau’s email subject for the title of this post, because that’s exactly what has happened.  Gigabit networking cards under DragonFly will perform very well under extreme load – all of them.

mxge(4) improvements


When Sepherosa Ziehau decides to improve something, he goes all out.  For example, he recently improved the mxge(4) driver for Myricom 10G network cards – which is for relatively older hardware – and improved performance by 150Mbps.

mxge(4), ecc(4) updated


mxge(4) and ecc(4) have been updated by Sepherosa Ziehau.  Not sure what’s new for mxge(4), a 10G network card driver, but ecc(4) now supports the memory controller for new Haswell systems.

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!

Details on dragonflybsd.org hardware


If you’re curious about the hardware being used for the colocated dragonflybsd.org servers (this includes the website, the repository, the mailing lists, dports build machines, etc.), here’s the ‘MicroCloud’ product page.  DragonFly’s model was purchased from iXsystems.   Apparently those Haswell processors have a fantastic power consumption to performance ratio.  (via)

Power savings and Haswell chips


If you have a computer with one of the very-very-new Haswell processors from Intel, Matthew Dillon has made some changes that will interest you.  They shave off (in the example given) about 20% of CPU power usage without much effect on performance.

KMS and i915 support in DragonFly


Thanks to the effort of a number of people, DragonFly (-current) now supports KMS and accelerated video on Intel 915 chipsets.  It’s 2D and x86_64 only for now, but it’s much, much better than just using the vesa driver.

Emulex OneConnect support added


Do you have a Emulex OneConnect 10Gb NIC?  Well good news!  Sascha Wildner brought in updated the oce(4) driver from FreeBSD to support Skyhawk models in DragonFly.

(My bad; looked at the wrong oce(4) commit originally and re-reported the import instead of the update.)

Emulex card support


If you have an Emulex BladeEngine 2 or 3, or an Emulex Lancer, it should work in DragonFly, thanks to Sascha Wildner’s recent commit.   Emulex has 10Gb network cards, in case you were like me and not familiar with the name.

(You thought I was going to type “Sepherosa Ziehau”, didn’t you?)

mps(4) users, take note


If you have a mps(4) device (LSI Fusion-MPT 2 SAS disk controller), you may be interested in Matthew Dillon’s large commit of bugfixes from FreeBSD.  Specifically, he notes that the drive gets ‘overtagged’, and performance can be greatly improved by reducing the number of tags used.

BSD Hardware ideas


PC-BSD now has a hardware store, with equipment known to work under PC-BSD.  Chances are good that if it works for PC-BSD, it’ll work for other BSDs or could be ported to do so…  (via)

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.

USB4BSD: not yet


The upcoming DragonFly 3.4 release will not include the USB4BSD port from Markus Pfeiffer; he’s hoping for it to become default in the next release after 3.4.

You can still try it, as it’s present in DragonFly but not on by default.  Help with driver porting is always welcome, of course.

mfi(4) users and foreign configs


If you have a mfi(4) device – in other words, a LSI MegaRAID SAS driver – you can now see/import/clear/etc. foreign configurations, thanks to this commit from Sascha Wildner, tested by Francois Tigeot, and originally from FreeBSD.

For the confused, ‘foreign’ means any disk hooked to a RAID controller that isn’t part of a configuration the RAID device already knows about.  A replacement disk, or more worryingly, a good disk gone bad/unrecognizable.  (I’ve had both.)

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:

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.

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 PCIonly, 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!)

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.

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.
