(I re-used the photo as it was quicker and because the UI still looks the same, anyway, five months later.)
Time for an update on where I got with the Pixel 3a / 3a XL so far:
I Am Getting There.
There isn't that much missing anymore. Will probably soon try this out as my daily driver, just did not yet have the time to configure all the applications I need. :)
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)
vibration (udev rule needs to be added to the corresponding package)
audio (ALSA config not packaged, but I'll get to that...)
Bluetooth™ (mac address has to be set after each boot, one single command, should probably package a script, still thinking about the right path)
eSIM (supported, but needs a bit more testing)
camera (front camera buggy, back camera works but patches not in git yet)
GPS (needs some improvements to accuracy)
This Does Not Work (Soon)
USB host mode
call audio (requires packaging q6voiced to get audio from the modem, but of course VoIP would already work)
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 That Prevail
A systemd unit with a hard-coded value, that has to be manually edited for now
ALSA config not yet packaged, has to be manually copied for now
few things to do for kernel packaging and then submitting that to Mobian
no call audio yet, as the daemon (q6voiced) is not yet packaged, but can be manually added for now (I'm considering just using VoIP until I can get to that :D)
simple script that brings up Bluetooth has to be added somewhere
Other than that, I cannot think of anything else that would be missing.
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)
Questions Accepted / Ask Me Anything About The Project
I will gladly answer all questions, I hope that more people will start porting if it becomes clear that this is not arcane magic. It's mostly just arcane. And a community of friendly people that try to be helpful.#
