sargo-temp

Temporary fixes that make Mobian work on sargo.

What to do

Build Image

Instructions can be found in IMAGE.md in this repo.

Flash image

First flash the image. Boot the phone.

Connect via SSH: ssh mobian@10.66.0.1

Accept the host key.

Roll out workarounds using Ansible

You have to have ansible-playbook installed.

Go to the Ansible folder: cd ansible

Roll out workarounds: ./workarounds.sh

Reboot phone via SSH.

Connect to wifi.

Rolling out the workarounds for audio requires installing packages from the repo, so we need an internet connection.

Roll out audio workarounds: ./audio.sh

Project Status

This Works

• booting
• display
• touch
• modem
• plymouth
• battery/charging
• mobile data
• wifi
• torch
• suspend
• SMS (only receiving was tested, but I don’t have reason to believe sending wouldn’t work)
• call audio (partly, I still need to sort out how to get the built-in microphone working in calls, it already works outside of calls)
• vibration
• audio (ALSA config not packaged, but can be manually added using the playbook in this repo)
• Bluetooth™
• eSIM
• camera (front camera buggy, back camera works but patches not in git yet)
• GPS (needs some improvements for better accuracy)

This Does Not Work (Soon)

• USB host mode (need to verify whether that's still the case or whether it can be used now)
• full disk encryption (no installer images yet, once the other stuff is done this will magically be there)

This Has An Unknown Status

• Fingerprint Sensor
• NFC (no idea what software I could use for testing, but should work, does so on pmOS)

This Is Missing And Will Come Later

• accelerometer
• magnetometer
• ambient light sensor
• barometer

The Main Issues To Solve

• A systemd unit with a hard-coded value, that has to be manually edited for now (droid-juicer.service)
  • https://gitlab.com/mobian1/droid-juicer/-/issues/4
• New release of qcom-phone-utils required so that my patches are available from the repo
  • 4f77281197
• ALSA config not yet packaged, has to be manually copied for now (the Playbook in this repo does that)
• A few things to do for kernel packaging and then submitting that to Mobian... or merge with patches for the qcom kernel somehow
  • patches are already being upstreamed by the sdm670-linux project, maybe that's already done before I start working on it xD
• no call audio yet, as the daemon (q6voiced) is not yet packaged (the Playbook in this repo compiles it and installs it)
• simple script that brings up Bluetooth has to be added somewhere (for now this repo contains a udev rule... but something is wrong with it. Run "/opt/bluetooth-mac.bash" to get Bluetooth working, repeat after reboots)
• udev rule for vibration has to be added to whatever package that is

The Sources (Use The Source, Luke)

• My efforts of packaging a device-specific kernel: https://salsa.debian.org/erebion/sdm-670-linux (which will be used until all patches are part of upstream Linux and we can finally use a regular mainline kernel)
• mobian-recipes, which is used to build images: https://salsa.debian.org/Mobian-team/mobian-recipes
• droid-juicer, which retrieves some important files from some partitions: https://gitlab.com/mobian1/droid-juicer
• postmarketOS wiki: https://wiki.postmarketos.org (lovely folks, thanks for sharing everything you found out the hard way :D)

Thanks For All The Fish

Huge thanks to be sdm670-linux project and flamingradian who runs the project (just one person!) to make sure the Kernel works on those devices! :)

I don’t know how Kernel development works, so I would have never started porting without this project.
