User:Halamix2/Getting things green
 |
this guide may be incomplete and completely wrong for your phone |
After initial porting there's still much stuff to do, let's get green in each field
Remember, every device is different and this guide will be rather generic
This guide assumes that USB Internet is enabled and phone has working USB net
Where to search
You can start your search for devices in
/sys/devices/platform/*
It should contain a list of some of the detected ones; sometimes devices are in one of the platform's subfolders, e.g. /sys/devices/platform/soc/
Touch and input
See also:
Install evtest, it should list all input devices it has found, wth possible states and shows log of detected actions
Wi-fi
See also:
XWayland
Try running xeyes, if it runs XWayland is probably available
FDE
See also:
Mainline
Mainlining have 3 different wiki pages
Battery
See also :
No idea how this works, on Nokia 1 you can find data bout battery in
cat /sys/devices/platform/battery/power_supply/battery/batt_vol
By reading batt_vol and dividing it by voltage_max it should be possible to calculate battery percentage
3D
glxinfo | grep "Device:" may help, usually when there's "LLVM" that means it's rendering in software See also:
- Software OpenGL
- Freedreno for Adreno GPUs (you might need to add support for non-flagship ones yourself)
- Mali-400 should have opensource driver too
Camera
HenriDellal suggested using motion
Modem

This guide is loosely based on User:Z3ntu/Fairphone2-mainline
Some devices won't work without binary blobs (Firmware) and there may be none opensource alternatives.
Some drivers may also be only available for Android, see Hybris
