ANNOUNCE: Guix on Aarch64 !!

ANNOUNCE: Guix on Aarch64 !!

[Efraim Flashner]

[-- Attachment #1: Type: text/plain, Size: 1163 bytes --]

Its my pleasure to announce that guix now has all the code necessary to
support aarch64! Currently support is limited to the core-updates
branch, but that shouldn't be too much of a problem, since currently
everything needs to be built from source.

For those interested in the numbers, I built (at least) 13 copies of the
bootstrap binaries while attempting to pin down bugs. I'm using an
Odroid-C2 with Debian as a base and a 32GB SD card. After supplying
dependencies and running bootstrap and configure, make takes about 25
minutes. It takes almost 16 hours, starting from an empty store, to
build all the way to hello. The board has a base of 2GB of RAM, about
256 MB of which is used for graphics, but I somehow managed to enable zram,
which I'm guessing helped.

In my quest for alternative architectures I'm considering converting one
of my old macbooks to the x32 pseudo-arch and seeing if I can get guix
working there too.

Great work!

I'm looking forward to trying it.

This is excellent!  Thank you for persevering!

Yay for more ports!

Yaaay!! I am already building on my arm64 machine! Well done! :D

Wow, awesome! I'm going to try it in QEMU.

Woohoo!  \o/

Congratulations and a big thank you for all the tireless work!

Let us know if there are still pending patches or anything that needs to
be addressed.

It would be great if you could start looking for an aarch64 machine to
plug into Hydra, or maybe start with a VM.

Thoughts?

Cheers,
Ludo’.

The odroid-c2 is under $50, I've been using that. Can be powered from the USB flashing port, comes with 4 USB ports, Ethernet and a micro-SD card slot. It does come with 2GB of RAM, some of which is lost to video, but I've had zram enabled and didn't run into any problems until I tried to build boost, which needed more than the 1GB of swap I had. 4xA53 isn't the fastest, but I'm pretty sure its the cheapest option for the RAM. Downside is that it isn't quite yet supported by mainline kernel but there are people actively working on it.

Firefly has a couple of boards with 4 GB of RAM but they're closer to $200 each. I have one ordered to see how that goes.

OK.  Once you have experience with the Firefly one, we could buy
whichever seems most appropriate, we have funds for that.

Thanks,
