Abstract

CyanogenMod supports ~70 devices at the moment. The goal of this talk is giving insight into the process of porting a device to the tree. Attendees will hopefully understand what needs to be done to make all device features fully operational while co-existing with many different devices.

Outline

Porting a device to CyanogenMod is (usually) not an easy task. There is an extensive amount of work behind a port that touches every single layer of the Android stack.

During this talk, I will be presenting a case study on how we ported 15 Sony Ericsson devices. While there is no specific formula for doing so, this talk will try to present a sequence of steps that we took in making these devices fully operational.

You can expect several advanced topics to be discussed, all in an interactive session where I expect people to interrupt if they have questions or suggestions. Among those topics, we will discuss:

  • Kernel changes
  • Hardware Interface Layers
  • Coexisting with other devices
  • Reverse Engineering
