May it be you have missed their latest apu2 board with a better cpu?

http://pcengines.ch/apu2b2.htm

According to their price list apu2 with 4GB ram costs the same as
apu1d4. A strange thing is that PC Engines is a bit shy on telling about
apu2 and only link to apu2 product page I could find is very briefly on
the bottom of their front page.

Thank you for the steer! Joy! ECC ram!

I ordered two from:

http://www.mini-box.com/site/index.html

I gotta admit that I generally don't need more than 64MB of ram and
16MB of flash... even pushing all 3 ports full throttle along with
wifi I think using up more than 256 would be hard....

Also pretty cool was this thing: http://www.mini-box.com/OpenUPS2

but I just blew my hardware budget for the month.

I have both boards and can say that they both very good networking
platforms - the apu1 has the small issue of the Realtek drivers for the
ethernet ports, Pascal has solved that i the apu2 by going with Intel
ethernet ports - My guess is that they won't do a full marketing push on
the apu2 until the bios for it is feature-complete (it's very close now).

Re: [Cerowrt-devel] trying a pcengines box

[Dave Taht]

Does the apu1 have BQL support for those realtek's yet?

I have always had very good results for the intel ethernet and they
were the first to get good bql support. so +1 for the design overall.
ECC! on home gear!

what OS do you run on them? (I am primarily debian/ubuntu/openwrt, but
in this case I think I'd lean ubuntu or debian)

(it's very cool to have coreboot, too)

Dave,

The APU1 uses the Realtek RTL8111E - these have drivers that work better in
windows than in Linux. Mainly I use OpenWRT, ipFire & pfSense, but I've
also tested Ubuntu and other Linux distros on it. For the APU2 ECC Ram was
one of the reasons I bought it - server class components for less than $130
is a bargain on this small boards.

Regarding BQL - I'm unsure if that feature/functionality has been
implemented yet on the driver for this device, but I can take a look later
this week.

Re: [Cerowrt-devel] trying a pcengines box

[Dave Taht]

Dear Luis:

Well, the boards arrived today...

Yea! The right gender serial port! A serial bios that...

I tried to boot ubuntu 16.04, from a usb stick, it goes right to the memtest
I put in tinyOS on the SDcard slot, it's not recognised as a bootable
option in the first place.
I enable pxe-boot, it doesn't show up in the menu
I read up on bootloader upgrades, it appears you need to have a booted
os to run the bootloader upgrade.

? How do I get the darn thing booted?

Aside from that ( :) ), it's a very good looking board that could do
exactly what I need, for two full length radios (or one half length
with an adaptor), I guess I'd find a machine shop to drill 4 new holes
for antennas.

I'm a little nervous about the heat spreader also - the single cpu
memtest hits 60C.

Put tinyOS on a USB stick.
What do the first two lines fron BIOS/Boot sequence look like on your board?

Depending on the BIOS version preloaded on the board it might be able to
boot from the SD Card until it has been updated. PXE-Boot has been added in
the latest BIOS image - the menu option to enable it is there but on older
BIOS images it doesn't do anything - on the other hand on the latest image
it is enabled by default and you will always get the prompt to hit the key
to boot into it - after 10 seconds it times out and continues the boot
sequence.

The male serial port is a hassle but I made an adapter to use the CISCO
style RJ45 to USB.
Did you get both the APU1 and APU2 boards?

Regarding the thermal envelope for the SOC on the APU2 - it's good up to
100C so 60 degrees is well below the threshold. I've read that some people
have had good results by skipping the thermal pads and applying thermal
paste instead between the SOC and the heat spreader - I haven't tried this
approach yet, but I'll give it try once I get to Central America and it's
tropical weather.

The APU1 runs a bit hotter at around 77C when the CPU is under load for an
extended period of time. But I've never had any issues - I'm tempted to try
the thermal paste trick on this one first.

Re: [Cerowrt-devel] trying a pcengines box

[Dave Taht]

dd-ing the image to a usb stick booted the board. Yea!

It also looks like there is some reasonable, if not complete, openwrt
support for it...

https://wiki.openwrt.org/toh/pcengines/apu

off to upgrade the bios next.

Re: [Cerowrt-devel] trying a pcengines box

[Dave Taht]

ok, I stuck the latest rom on the boot stick, successfully updated the flash,

Impressive - there's 1 day old ubuntu 16.04 support for it... I had a
bit of trouble partitioning the msata card
and ended up installing it on a sdcard (am watching it do a netinstall
from the main site *overipv6!* which is a bit slow), will try harder
to get the install more local (not sure how)

Yes, you just dd the image for the APU2 and then upgrade/downgrade the BIOS.
When I tried it, it didn't correctly mount the FAT partition, but it was
located under /media/SYSLINUX - so if you need to change the ROM this is
where you would look for the files.

What problem did you have with the mSata drive?

Re: [Cerowrt-devel] trying a pcengines box

[Dave Taht]

I have it built and running 16.04 off of the msata card now. :woot:

last major trick - always install openssl-server before rebooting.

(I haven't figured out how to make systemd do a serial console either, yet).

I am running tests continuously overnight... I imagine I should
configure lm-sensors for it? irqbalance?

running cake on it without shaping eats 100% of cpu (1/4th of cpu)
shaping two ports to 900mbit ate about half but  misbehaved. (never
got close to 900mbit)

How about FQ_CODEL?
Does it eat up the CPU at the same rate when shaping?

Haven't got round to it yet. Shaping to a gigabit has not been a goal
for me generally, on this low end hardware - 400MBit - about double
the current max of what I can get from comcast, is. I HAVE noticed
that the hardware can kind of "hang" for an interactive ssh session
using the default mq + 4 pfifo_fast queues vs the flent rrul benchmark
at a gbit, which is a bit surprising.

Switching to mq + fq or mq + fq_codel fixed that in theory at line
rate... but in all cases the results were very odd... (see attached -
I think it's mostly the ac1200 acting up - I'll put a saner target up
for that benchmark soon). I will do more comprehensive benchmarks, but
those of you using it as a router might benefit from setting
/etc/sysctl.conf to have

net.core.default_qdisc=fq_codel
net.ipv4.tcp_ecn=1 # if so inclined
# I tend to also use notsentlowat

and

# Sometimes sysctl runs too late to get on by default you may need to try
# putting in a file /etc/network/iface.pre.up/debloat

#!/bin/sh

[ "$IFACE" != "lo" ] || exit 0

tc qdisc del dev $IFACE root
tc qdisc add dev $IFACE root fq_codel # ignore hw mq
# tc qdisc del dev $IFACE root # if you want to give mq + fq_codel a shot
# no I haven't tried integrating sqm with this yet
exit 0

Definitely it's a terrible idea to use pfifo_fast on a router.... am
concerned about no hpet timer...

...

I did manage to get one to take an ath10k card... I LOVED the honesty
in the relevant doc on it:

http://pcengines.ch/wle600vx.htm

"Software support Expect some pain, ath10k drivers required."

bricked another one (temporarily) somehow with a kernel update (does
this thing use grub?)

I am attempting to melt one by doing a kernel compile on it as I
write, but my older tree blew up with

include/linux/compiler-gcc.h:103:30: fatal error:
linux/compiler-gcc5.h: No such file or directory compilation
terminated

... and all the other joys of attempting a new platform. I should
probably not bore you with this but blog

...

I installed lm-sensors (I do worry about heat and could, for example,
overheat my last rangeley box easily on a compile) - not sure what
else can be done to govern power vs heat on this platform, I don't
know if this is measuring the right stuff...

# sensors
fam15h_power-pci-00c4
Adapter: PCI adapter
power1:           N/A  (crit =   6.00 W)

k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +59.9°C  (high = +70.0°C)
                       (crit = +105.0°C, hyst = +104.0°C)

ath10k_hwmon-pci-0400
Adapter: PCI adapter
temp1:        +28.0°C


...

it is really nice to have 64GB of ssd to play with on a router....

...

I hate GRO. I am told a means to minimize GRO to be less aggressive
now exists in ethtool but I don't know how it works.

Latency seems very much under control with even a small spike to 2ms, when
most of it keeps right under 1ms. How much of a performance hit (% -
percentage wise) are you taking on the bandwidth throughput?

Huh, it's supposed to just work, following the kernel settings.

pasting from Google cache, as Poetterings blog is down -


To make use of a serial console, just use console=ttyS0 on the kernel
command line, and systemd will automatically start a getty on it for
you."

By default systemd will instantiate one serial-getty@.service on the
main kernel[4] console, if it is not a virtual terminal

This logic is implemented in a generator called
systemd-getty-generator that is run early at boot and pulls in the
necessary services depending on the execution environment.

sometimes there's the need to manually configure a serial getty, for
example, if more than one serial login prompt is needed or the kernel
console should be redirected to a different terminal than the login
prompt. To facilitate this it is sufficient to instantiate
serial-getty@.service once for each serial port you want it to run
on[7]:

# systemctl enable serial-getty@ttyS2.service
# systemctl start serial-getty@ttyS2.service

Sometimes, there's the need to configure the login prompt in even more
detail. For example, if the default baud rate configured by the kernel
is not correct or other agetty parameters need to be changed. In such
a case simply copy the default unit template to /etc/systemd/system
and edit it there:

# cp /usr/lib/systemd/system/serial-getty@.service
/etc/systemd/system/serial-getty@ttyS2.service
# vi /etc/systemd/system/serial-getty@ttyS2.service
 .... now make your changes to the agetty command line ...
# ln -s /etc/systemd/system/serial-getty@ttyS2.service
/etc/systemd/system/getty.target.wants/
# systemctl daemon-reload
# systemctl start serial-getty@ttyS2.service

This creates a unit file that is specific to serial port ttyS2, so
that you can make specific changes to this port and this port only.


[7] Note that this systemctl enable syntax only works with systemd 188
and newer (i.e. F18). On older versions use ln -s
/usr/lib/systemd/system/serial-getty@.service
/etc/systemd/system/getty.target.wants/serial-getty@ttyS2.service ;
systemctl daemon-reload instead.

No, in my world a female serial port is a hassle, being able to use this
