Lineage OS kernel sources for Exynos 7580 Devices
Compiles
- Linux kernel 3.10.108
- Device information
What's working
- Hardcoded kernel arguments
- Making a PMOS Recovery zip
- Flashing using custom recovery
- Showing splash screen during boot
- Starting full X-Session and using the UI with USB-OTG Keyboard and Mouse
- Running LXQt or SXMO
What's wrong
- When the phone boots it shows the splash screen meaning the rendering is working. But it crashes and force reboots soon after. - This is probably caused due to the fact that the init is messed up because the bootloader passes the wrong kernel arguments. The ones that are used to boot android. - But this issue has been fixed
- Being unable to mount the system partitions in TWRP to check logs or modify the system. - This is a common issue in many PMOS builds.
- Display manager not showing up after starting up
- WiFi and Bluetooth hardware not being detected or initialized.
- LightDM Failing to start properly. Causing it to not boot into desktop automatically
