Why Android kernel ?

  • An Android kernel is a mainstream Linux kernel, with additional drivers for the specific device, and other additional functionality, such as enhanced power management and faster graphics support.
  • Many features in the Android kernel are later added to upstream Linux after the open-source community has accepted.
  • When compared to Linux kernel, the Android common kernel has 355 changes, 32266 insertions, and 1546 deletions (as of February 2018).
  • Android kernel is more popular and has more footprints compared to linux kernel which leads to more support world-wide
  • SOC vendor supporting android kernel doesn’t need to  work to provide linux kernel support  to  bring in RDKV stack.
