Running Mainline Linux on Snapdragon 410

How we support over 25 devices in postmarketOS


The Qualcomm Snapdragon 410 (msm8916) is a SoC that was used in many smartphones and tablets around 2015. It is the most mature "aftermarket" platform postmarketOS can offer at the time of writing. Many of the supported devices are quite usable and have most of the expected features like phone calls and mobile data working.

The talk goes over some of the most important challenges that we have faced while supporting those devices and describes the ways in which we have solved them.

Apart from the Linux kernel, we focus on various other tools and projects like lk2nd - a shim bootloader that prepares the environment for booting Linux and hides some device-specific quirks from the kernel. It also unifies the boot and installation process on all devices.

We also have other tools and resources to make porting easier. Those include various documentation or even a fully automated display driver generator that helps with the fact that each display requires unique initialization.
