Hello Guix!

I'm pleased to announce that the 'wip-armhf' branch is now ready for
wider testing.  So far, I've successfully used this branch to:

(1) cross-compile armhf-linux bootstrap tarballs on my Libreboot X60,

(2) natively compile armhf bootstrap tarballs on my Novena, based on the
    cross-compiled bootstrap tarballs from (1), and

(3) build the 'hello' package based on the natively-compiled bootstrap
    tarballs from (2).

Most likely we'll find more build problems higher up in the stack, and
help with that would be most appreciated!

   Happy hacking,
       Mark

Wow, great progress!  I will start testing when my Novena arrives.

Congrats on all the progress made!

It would be nice to have a couple of build machines for this platform.
If anyone reading this wants to help, please let us know!

On which kind of machines does this armhf run? Is it related to the output
of "uname -m"? I have a raspberry pi that identifies as "armv6l", and a
seagate goflex that identifies as "armv5tel". I suppose both are too old
to run armhf? If it is not "uname -m", how do I know whether the port
will work?

Our armhf targets the same set of machines as Debian's armhf, namely the
ARMv7-A architecture with VFP3D16 coprocessor.  So 'uname -m' must
output "armv7l" or better, and I guess the processor "Features" as
reported by /proc/cpuinfo must include "vfpv3" and either "vfpd16"
or "vfpd32".

Right, they can't run armhf.  Also, a build slave should have 1 GB RAM
minimum (preferably 2) and reasonably well performing storage (i.e. SATA
not SD).  So, I think Beaglebone Black and other systems in that class
will not be sufficient.

I think we need ARM board(s) with performance comparable to the Novena.
The Novena itself would be a fine option, but I'm not willing to give
mine up for that task :)

Since it’s becoming a FAQ, could you add something along these lines to
the manual, right where armhf-linux is introduced?

Thanks,

I already put this in the "GNU Distribution" node (chapter 6):

--8<---------------cut here---------------start------------->8---
   The GNU distribution is currently available on the following
platforms:

[...]

‘armhf-linux’
     ARMv7-A architecture with hard float, Thumb-2 and VFP3D16
     coprocessor, using the EABI hard-float ABI, and Linux-Libre kernel.
--8<---------------cut here---------------end--------------->8---

Do you think more is needed?

Perhaps in parentheses or in a footnote indicate what to look for in
“uname -m” and /proc/cpuinfo?  WDYT?
