Guix received one but we have so far be unable to get the GuixSD flash
image because something always breaks on Hydra before it's done (for
example lack of disk space - see https://hydra.gnu.org/build/3198097/log/raw .
Note: The latter thing counts as "successful" build.  WTF?).

I have the device here in my hand (I tested it using u-boot only - works fine).

I'm now setting up my own build server and trying to get the flash image
that way - which is ridiculous.

Also, be aware that the Allwinner A20 is really really slow.  There are
ARM computers worth using as a normal PC, but this one isn't.  I tried.

(For example the Allwinner R40 is quite okay to use as a PC - see
Sinovoip Banana Pi M2 Ultra)

I like the concept of easily upgradeable computers, though!

Is this now better with ci.guix.info (berlin.guixsd.org)?

Oh, so it works out of the box with GuixSD already?

No idea.  How to I get the flash-image using ci.guix.info ?

I tried "guix system disk-image --system=armhf-linux gnu/system/install.scm" but
that builds a lot of stuff from source.  Let's see whether it will be done before
the sun exploded :)

As I said, I've tested it with u-boot only so far.

I’d suggest trying again, and possibly retrying a bit later so that
substitutes have had a chance to be “baked”.

hydra.gnu.org and now ci.guix.info both provide armhf-linux substitutes.
They have much less armv7 CPU power than x86 but still, it shouldn’t be
that bad.

This sounds like two distinct bugs:

* Regarding the lack of disk space: if I'm not mistaken, as things are
  currently implemented, we must specify the size of the disk image
  manually.  I guess we need to increase the size.

* This error that occurs within QEMU is apparently not being propagated
  to the outer build script.  That should be fixed.

You seem to be assuming that the problem building the disk image is a
Hydra-specific problem.  Do you have reason to believe so?  I would
guess that these bugs are in the disk image builder.

What do you think?

Ah, you are right!  https://hydra.gnu.org/build/3194622/log/raw (the usb-image
for i686) also fails - but nobody noticed because we only distribute the iso
image (which determines its size dynamically).

I didn't make the connection that this is a fixed-size guest filesystem before.

Yes.

Probably!

According to the progress bar it's missing an additional 40% ?  That's... large.

I've increased the size for the time being, but according to the logs
it was at 800 MiB in 2015.

This indicates that /dev/kvm on hydra.gnunet.org has permissions that
prevent the guix build user from accessing it.

I raised this issue long ago (2015) on the guix-sysadmin mailing list.
In that message, I noted that on hydra.gnunet.org, /dev/kvm has mode
0600 and is owned by root, which caused our disk image derivations to
fail.

At the time, Ludovic chmod'd /dev/kvm, and mentioned that he had tried
to make this persistent via /etc/udev/rules.d/70-persistent-net.rules,
but that for some reason that didn't seem to work, possibly because it
was being overridden by another rule or startup script.  As far as I
know, we never implemented a proper fix.

Ludovic, for now, can you chmod it again?

     Thanks,
       Mark

I did that again this morning.

Apparently there was a typo in the udev rules I had written: “=” instead
of “==”…  Should be better now on the next reboot.

I believe you can download it by running:

  guix build /gnu/store/ywrh286iqc3jlfhjqsvs22gmcr02i2bp-disk-image.drv

If you don’t have this .drv, you should be able to build it from commit
cba7ddcf603455c6692eb50c8bbf203a6bf17ab1.

See all the details at <https://hydra.gnu.org/build/3255541>.

The solution I proposed only works if you’re using /gnu/store as your
store prefix.  Otherwise you cannot get substitutes from the build
farm.  :-/

This looks like the issue fixed in

I do use /gnu/store , but I think the above was from a "guix" package unit test.

Indeed.

Now po4a fails one of the tests.  It's not easy to get the image :)

I'll try some more...

although the problem seems to lie somewhere else, I would just like to
point out that you can use your account on bayfront to build things for
arm as well - it offloads to the redhill machine. Notice, however, that
this is a single machine building everything from source without using
the hydra or berlin build farms for substitutes.

I can also give you a direct login on redhill if you need it.

this is the mysterious error message we have seen before: There is still
plenty of space on all the machines! I think it was related to an ext4
limitation on the number of files, or the number of files inside a single
directory. I ran some garbage collection on bayfront, and it can now offload
and retrieve builds again. Please give it another try!

I looked again at the code and found the issue, now fixed in
adb158b7396cbdcda347fa298978408e531a03fd.

We’ll have to update the ‘guix’ package and deploy it to actually get
the fix.

Thanks,

Hi Andreas,

can you check whether dirindex (hashtables for directory) is enabled?

# tune2fs -l /dev/... | grep -o dir_index

It was, and I disabled it. Hopefully this does not break anything...
But does this not mean a big performance hit on /gnu/store/.links?

Why did you disable it?

> But does this not mean a big performance hit on /gnu/store/.links?

I would expect disabling dir_index to be a big performance hit on Guix
systems, and especially those with a large store, such a build farm
master nodes.

It does mean that because it uses a linear search to find the file names now.

What ext filesystem is it?

https://en.wikipedia.org/wiki/Ext4 says that ext4 supports B trees - which
should have no problems with hash collisions (it uses operator< to construct
a tree -- and not hashes to construct a list).

Because we get exactly these spurious ENOSPC mentioned in the blog post
on bayfront when the disk is only one third full.

Now I am happy to try out any other combination of flags that solves the
problem.

So should I add dir_index again (is this possible live?), and then
add large_dir?

Did you reconfigure?

# guix system reconfigure /etc/config.scm

If so, that's weird.

>I'm on x86_64 hardware running a i686 guix

Yeah, "--system" is using qemu to emulate the target architecture and the build
job then runs in there.

bug#33676: GuixSD on eoma68-a20?

[Luke Kenneth Casson Leighton]

hi folks,

good to see there's progress on this.  do make sure to use a UHC Class
10 micro-sd card (the ones that say they are 75-80mbytes/sec), they
will happily run at 20-25mbytes/sec read/write speed, which is about
the same speed as an SSD from around 2012.

you should get a boot to xfce4 or lxde of around 20-25 seconds: again,
comparable with a budget processor from around 5-8 years ago (which is
what this is).  for god's sake don't peddle gnome3 or kde4 at
end-users.  the performance will be absolutely atrocious, absolutely
guaranteed.

yes, the idea is to upgrade (and sell or repurpose the old one).  this
is the *first* in the series.

for building can i recommend using "-Wl,--no-keep-memory" and report
if it helps, here:
https://sourceware.org/bugzilla/show_bug.cgi?id=22831

there is a slow-boil linker problem which is similar to the "640k
should be enough for anybody" - all of the quotes historic quotes
techniques which used to be implemented to make it possible to link
programs where there is not enough virtual or physical memory have
been ripped out because "4GB should be enough for anybody".

firefox now requires a staggering SEVEN GIGABYTES to successfully
link.  this is insane.  please do try that linker option because
otherwise people will believe that 32-bit hardware needs to be
destroyed, due to it being utterly useless.

Yes, I got such a card now, seems to write (including sync) quite quickly
on my laptop at least.

I understand.

Yeah, we've now added the linker option to several packages.
It improves the situation a lot.

 GREAT!  i'll cross-reference to the sourceware bug, that's really
good to hear.  it's not perfect: really, ld needs to be massively
improved, bringing back techniques that were deleted from the source
code at least 15 years ago.

OK.  There has been quite a lot of work getting Guix System running on
various boards since this was opened, so I don't expect porting to
EOMA68-A20 to be particularily problematic.  Closing for now.
