pcengines apu{1,4} can't adjust CPU frequency automatically anymore

[Lévai , Dániel]

Hi all,

I don't know since when, unfortunately, but it seems auto-adjusting CPU 
frequency doesn't work anymore on my APU1 and an APU4 PCEngines boards (I only 
have these versions at hand atm).
They're both running an updated fw at v4.17.0.2.

IIRC `apmd -A' + `sysctl hw.perfpolicy=auto' did the trick earlier, but I'll be 
honest, I haven't checked this since forever.

APU1 has two and the APU4 has three frequencies to set:
cpu0: 1000 MHz: speeds: 1000 800 MHz
cpu0: 998 MHz: speeds: 1000 800 600 MHz

I can manually adjust this with hw.setperf when hw.perfpolicy is 'manual', so 
setting the frequency actually works, it's just that it can't seems to "detect" 
load/change when it's set to 'auto'.


Daniel

We need more information to better assist you.

By LDOM, do you mean you want to use Oracle VM Server for Sparc? Does
that even run on OpenBSD?


He obviously talks about OpenBSD technology ldomd(8) ;-)



Or are you using OpenBSD’s native vmm?

Are you using the Sparc or Intel version of Solaris 9?

Which architecture does the host machine use?

Would you please post a full dmesg of the host machine?

IPv6: ifconfig & rad messages fight disabling routes

[Geoff Steckel]

Short form:
  I'm using rad to update local machines with the IPv6 address prefix
currently assigned by Verizon. It runs on my firewall/external router.
The router advertisement destructively changes the route and interface
of an address on that machine.

dhcpcd gets /56 from Verizon fiber service.
manually ifconfig interface1 inet6 ::9/56
netstat -rn -f inet6 shows
  :: and ::9 routed via interface1
everything works.
rad message sent out from interface1:
  /56 valid 1000 preferred 1
netstat now shows
   routed via lo0
  ::9 is still on interface1
That address is now (mostly) unusable
Other addresses assigned to that interface work.

Is this expected?
Possible workarounds:
  blocking loopback of router advertisements (preferred)
  dhcp6 server for guest machines & fixed assignments
  for servers/test machine (inconvenient or worse)
  Monitor prefix for changes - hope that's not often

I have to assume the mechanism which processes RAs follows the
RFC and uses the link level address of the sender.
I hypothesize it sees lo0 as the sender
and Bad Things happen.

As already pointed out by others. Don't do that ;-) Unless you explain

much)


I build systems running for eg. 12 years, amd64 architecture, SATA 
disks,

DDR RAM and so on. Serving number of virtual machines with constantly
higher number of utilizations and in dozens of them only 2 problems
during those years - battery for internal RAID run out :-)

Saw systems which were running for over 30 years and nothing wrong 
with

them.

Can't talk about electricity as those are basically underground cities
and there are different problems then if CPU is running 3 or 1GHz ;-)

Sounds like maybe some IoT solution, but then go for ARM or use 
virtual

machine in eg. OpenBSD Amsterdam or you really need compute power on
demand then go for free options in eg. Azure (12 months free basic 
Linux)

or Oracle Cloud Infrastructure or whatever else you find fit.

Either it is so important, need to be physically under your control 
and
then small differences in electricity does not matter or solutions

are perfectly fine for your needs.

Just one hint. No matter if own machine or something rented you want

So to sum up your requirements, you want a self driving box which
waits, and once every month or six wakes up, does something, then goes
idle again.

I would avoid power down/up completely - boot takes time, and fsck
takes some more time. Also, AFAIK electronics wears down every time it
goes on-off.

Modern HDD are said to live to 5 on-off cycles, so assume 2
cold boots. But random things can happen, because on-off means power
spike. If you have no problem with eletricity, I would keep it going
all the time. I would however minimise writes. Work on temporary data
in ramdisk, write results to disk. Something like this.

BIOS battery goes down faster when computer is powered down. When it
is up, clock gets power from the wall and saves the battery. I assume
the modern CMOS battery will only keep the clock for about a year
without power and it will not recharge when you power up. After that
time (and before that time, too, but less necessary), every boot
should include query to time server and adjusting the hardware clock.

I would buy a decent PSU. Last time I wanted to know, Seasonic was the
maker of best ones a mortal could buy. Their last unit I bought came
with 10 years warranty. AND, according to description, it was built
with classic electronic art, analog parts, no digital. So if you are
so inclined, you can ask your electronic buddy to inspect it and
perhaps even replace some parts with better ones. Or repair it. If
microcontroller goes bunk, you are out of luck, I assume they somehow
protect their eproms.

If you plan to store some long term data on this box, I would avoid
SSD. They are fast but they also can go bunk and when they do, chance
of recovering data is close to nil (from what I have read).

I would consider putting the box in a plastic bag to protect from dust
and humidity. Dust will clog into radiators, make chips go hotter,
ventillators work harder. I have not tested this, however. I assume
thermal exchange with loose bag over the box should go ok, but you
need to test it very carefully, monitoring temps all the time - all
temps.

"Does it just need to wake up to run a script and then shut down again" -> yes, 
that's basically that. Of course, requirements might evolve.
"Why does it even have to be a separate machine?" -> There are benefits to 
this, including data safety (different location).

Thank you for your help, have a great day.

HDD is likely better for medium-term storage (especially if the device would
be powered down).

Or get a remote power controller, set the machine to autostart on rexovery
after power loss, and shut the whole thing down until you need it.

RAID 1C: Writing Random Data During Installation

[Puru Shartha]

Namaste Misc,

ASSUMPTION
Consider two disks sd0 and sd1 assembled into sd2 with RAID 1C as the
discipline.

QUESTION
Which of the following is the correct way to write random data for the
RAID 1C discipline during installation?

1) # dd if=/dev/urandom bs=1m 2>dd.result | tee /dev/rsd0c > /dev/rsd1c
In other words, writing random data to the disk before initializing the
disk (fdisk), creating the partitions (disklabel) and assembling the
softraid device sd2 (bioctl).

2) # dd if=/dev/urandom of=/dev/rsd2c bs=1m
In other words, writing random data to the assembled disk sd2.

3) Both of the above.

CONTEXT
>From the Full Disk Encryption section of Disk FAQ [1]:
"
...
You may want to write random data to the drive first with something like
the following:

# dd if=/dev/urandom of=/dev/rsd0c bs=1m

This can be a very time-consuming process, depending on the speed of
your CPU and disk, as well as the size of the disk. If you don't write
random data to the whole device, it may be possible for an adversary to
deduce how much space is actually being used.
...
"

>From my limited understanding, this concept of writing random data
is applicable for the RAID 1C discipline as well.

However, the guidance on this is missing for RAID 1C discipline.

Hence the question.

Hey Mike,

You can look at /usr/src/sbin/wsconsctl/map.parse.y (or browse
cvsweb.openbsd.org if you don't have sources locally). It is the yacc
file for the syntax of parsing keyboard.map statements. It's close to
BNF if you're unfamiliar with yacc, i.e. it formally describes the
grammar.

/* Parse a keyboard map. Statements are one of
 *
 * keysym sym1 = sym2   Assign the key containing `sym2' to
 *  the key containing `sym1'. This is a copy
 *  from the old to the new map. Therefore it
 *  is possible to exchange keys.
 *
 * keycode pos = sym ...assign the symbols to key `pos'.
 *  The first symbol may be a command.
 *  The following symbols are assigned
 *  to the normal and altgr groups.
 *  Missing symbols are generated automatically
 *  as either the upper case variant or the
 *  normal group.
 */

As mentioned earlier, the keysyms and commands and groups are listed in
/usr/src/sys/dev/wscons/wsksymdef.h . Around line 485 you get into
modifiers, function keys, and command keys.

For educational purposes, you can go check /usr/src/sbin/wsconsctl,
where e.g. util.c lists keyboard types. Another place is
/usr/include/dev/wscons/wsconsio.h which also lists what tokens
wsconsctl likes. The wscons driver is in /usr/src/sys/dev/wscons (also,
man 8 wskbd), and keyboard drivers are also thereabout (man -k kbd &&
man -k kbc). You can check `wsconsctl keyboard.type' to see what you
have, then check that driver for scancodes.

Scancodes are keyboard specific. E.g. for PC keyboard or USB keyboard,

Some Corroboration of that:  a Ph.D. physicist at a major semiconductor
manufacturer told me that power cycles cause more wear damage to memory 
chips (at least) than heat does (assuming somewhat normal use I 
imagine).

It might, at least they recognize (in smarttools)
the number of hours spent rorating.

But as I said, I don;t thnik it's even worth it.

So how often is the machine up (per year) and for how long?
Does it just need to wake up to run a script and then shut down again?
(Why does it even have to be a separate machine?)

In the case of an SDD, is there no consideration of turning them off, if they 
are unused for some time?
In the case of HDD, are you saying that putting them in "spun down" mode 
actually would not increase their lifetime?

The CPU isn't going to "wear out" due to being running, at least not in
a meaningful time scale.

HISTORICAL EVIDENCE hints that a spinning drive will last longer than
a frequently power cycled drive.

Steady-state is easiest on hw.  Powering up and down is large power
surges, and that's generally not good.  This is across the board --
power supply, hard drives, main board, CPU, memory, etc.  The only
part that I think gets a benefit from being turned off would be a CRT
monitor, and maybe the HV in an older LCD monitor.

That's based on historical experience with a lot of different machines.
How that relates to the hardware you have at hand, there's no way to
know, other than get 50 identical machines, power one half on-and-off
regularly and leave the other half on.


Yes, I do know in advance when the machine needs to run and when it
can sleep.

"Some machines have a wake option in their BIOS." -> thanks for the
pointer, I will look into that.


That might work for you, but I think your premise is flawed.
 

"How much electricity have you saved by that?" -> I don't know. The
main concern is not using the hardware unnecessarily, to hopefully
increase its lifetime. Though less electricity usage is a nice side
bonus.


I just did some measurements here before seeing these replies.  Short
version: single 4TB 3.5" 5400 RPM drive draws less than 7W when
running...and I doubt you get all that power "back" when you spin
down the drive.  CPUs mostly draw power when doing something, the
difference between an mostly idle CPU running at 1GHz vs. 3GHz is
fairly small.  And on a rack mount server, fans may draw more power
than an idle CPU.


"How much resources would that save?" -> My thoughts was that it
would be better for hard drive longevity to have them spun down,
rather than them being up for months without any access needed. I
don't know in practice if that matters for life expectancy of the
drive?


As someone who has seen a lot of hard drives power down working and
not spin back up at next power-on...I'm pretty sure your plan is
absolutely defeating your goal.  I'm pretty sure a whole lot of
other people are also screaming "NO!!!" at their computer right now.
I hold a lot of unpopular views based on my experience, but I'm pretty
sure "leave drives running for maximum life" is NOT one of them,
it's pretty mainstream.

From your elaboration on your goals, just leave it alone.  By trying
to make it a super-efficient system, you are going to increase your
downtime and failure in a number of ways.

The CPU is not being "worn down" by running.

As for rotating metal disks, they have a lifetime;
that's why replacing them with SSD might be your best bet.

But even regular disks are dirt cheap now.
I don't believe this concern is even worth the time spent on this.

Then you can set a wakeup alarm in the BIOS (if it has one),
and simply shutdown -p via cron, at the appropriate time.

Wait, so you know in advance for how many _months_
the machine can sleep?

"I have been able to lower the CPU speed by running `apm -L`."
For automation purposes consider using obsdfreqd (pkg_add obsdfreqd)

Configure OpenBSD for remote server rarely used

[James Johnson]

Hi all,

OpenBSD is amazing. But I need help in configuring it correctly as a remote 
server, rarely used.


The main thing I am trying to do is to make it sleep every now and then to 
protect resources. I am very flexible on how to do this, but have been unable 
to do so.
Here's what I tried :

1) Make it sleep and wake up when woken up remotely
I investigated Wake On Lan, which I enabled via ifconfig. However, this system 
is deployed remotely, and I have no access to other computers on the LAN, so I 
am unable to make this work.

2) Make it sleep for a few hours and then wake up
After 3hours+ of research in man pages and the internet, I have not seen any 
solution for that.

3) hard drives Spin down, CPU lower freq

I have been able to lower the CPU speed by running `apm -L`.
I haven't been able to spin down the hard drives.
How important is it to manually send a command to spin down the unused 
harddrives? Will it be down by the system automatically?

I am trying to get info on the drives from the system but `atactl sd0 
checkpower ` always shows `standby` even after I have just written on the disk. 
I understand this does not work because my drives are SCSI and not ATA.
I read the man page for scsi, and I see the command to spin down hard drives : 
`scsi -f /dev/rsd2c -c "1b 0 0 0 0 0"`
However, I see no command to spin them back up. Is it automatic?
How can I request information on the spin state of the drive. I am just a 
little worried about starting to send low levels instructions to the hard 
drive, with little understanding of it. Is it safe to send this command?

Thanks all !


PS : dmesg : I cannot share the full dmesg for security reasons, but it is a 
fairly standard i386 machine, with 2 drives mounted as SCSI.
