SFO15-210: Kernel Mainline Status of Mobile Chipsets Speaker: Tim Bird Date: September 22, 2015

★ Session Description ★ In this session, Tim Bird will discuss the mainline status of several ARM SoCs used in mobile products. The average phone uses kernel software that is 3 years old, 20 versions behind mainline, and has 1 to 3 million lines of code out-of-tree. Tim will describe the “Device Mainlining” project of the Linux foundation CE Workgroup, which seeks to address this problem. Some of the activities of this project are:

  • publishing tools for mainline analysis
  • finding big areas where multiple vendors have code out of tree
  • identifying institutional barriers to corporate developer mainlining, and addressing them through education, training, and collaboration
  • working with upstream to address deficient sub-systems or needed maintainer assistance It is hoped that discussion will ensue about ways to continue enhancing this work, to get more SoC code mainlined.
