This is a meta/tracker bug to track what needs to be done and what is
already done, to run Guix system on the Purism Librem 5 phone.

The Librem 5 will be shipped with a mobile optimized GNOME based on
PureOS which is based on Debian, but contains only free software :)

As the phone and the software is still in heavy development, we don't
know yet what exactly is required to have a proper "phone" experience.

Hardware spec:
SoC: NXP iMX8M Quad Core
arch: aarch64
storage: 32GB eMMC

GNOME and it's packages should be on the newest versions, as they could
contain fixes and improvements for a mobile UI (responsive).

The following packages are still missing in Guix or may need adjustments.

Kernel/boot:
- kernel: At the moment there are surely patches on top of linux-vanilla
required, but Purism pushes hard to upstream those. So maybe no
special is required when the phones ship.
- u-boot-imx: U-Boot for iMX, they have still patches on top of

Core libraries:
- libhandy: provides responsive UI stuff for GTK, may becoming
dependency of some GNOME packages https://source.puri.sm/Librem5 /libhandy
- phosh: Wayland shell (prototype) for GNOME on mobile devices:

Leaf packages:
- calls: App for calling, backend ModemManager or oFono
- chatty: App for SMS and XMPP messaging:
- epiphany/GNOME Web: They have some patches for mobile UI:
- gnome-contacts: Missing in Guix, they have a phone-focused fork:

Feel free to add comments, other bugs which are related or relevant
links etc.

Further "audio" packages:
- wys, daemon for PulseAudio loopbacks for phone calls:
- haegtesse, daemon for audio between modem and PulseAudio. Seems to
only be used on the developer board:

Core:
- phoc, wlroots based phone compositor https://source.puri.sm/Librem5/phoc

Leaf packages:
- kgx (King's cross), a simple terminal:

On the Guix days there was a session about running Guix on mobile
phones. The notes will be published somewhere else. Don't know when and
where yet.

Patch for chatty:

On my personal (dirty) wip-librem5 branch on Gitlab.com is additionally
software for the Librem5:
phoc: successful build, somehow working
phosh: successful build but not yet running
purple-mm-sms: successful build, don't know if it's working as I lack
modem for testing
calls: not yet pushed, depends on updates (meson) who are not yet in
master, but on core-updates

I too hope guix system can work on L5, but it looks like guix system
itself has a long way to go. IIRC, L5 is aarch64, and there are
problems running guix (package manager) on aarch64. If L5 is armhf
that's possibly a little better, but it still needs a lot of work.

Thanks for doing this!

I think I saw somewhere in the purism docs how to emulate a modem for
testing. I'll send a link if I find it, or you can ask in their matrix
rooms.

If you use this branch as a channel, you can take the necessary meson
updates and dependencies from core-updates to test things. Just make
sure you're prepared to rebuild the world.

Another thing to consider is the bootloader. Last I checked the librem
5 u-boot still isn't available in the current u-boot packages.

Thanks again for working on this!

The Librem5 is aarch64 based. I think you mixed something here. aarch64
runs fine with Guix, armhf has some problems with Guile 3.0 ATM. So I
don't think the way is so long.

Oh that is interesting. My laptop has a 3G modem (Ericsson N5321). I'll
try to test stuff with it. But I'm not sure if it supports SMS and calls
at all.

I know, but I guess I'll just wait. As the phones will likely ship in
July, I have no real time pressure :P

I'm aware of that. We probably need a "custom" u-boot package for the
Librem 5.

chatty was merged as d26186232ed4c753db73c6a0d2c623d2816e721d in June 2020.

phoc and phosh are still bitrotting in a not really functional state in
my personal repo. I need to revive that...

Hi,

there's a new alternative to Anbox [1]. I've created patches that aim to bring the support [2].

Cheers
Petr

Hi,

I have a patch open for sxmo-st from January 17:


It is the simple terminal used on the sxmo pinephone distro:


I have the other packages from the sxmo suite packaged here:


I can send them all if there is interest in merging them upstream.

all best,

jgart
