KMS HWComposer issues, the Atomic Display Framework and other KMS Extentions

This proposal has been accepted as a session.


One Line Summary

Discussion around issues with a KMS based HWComposer, the Atomic Display Framework, and other KMS extentions


Various folks have been looking at implementing a KMS based HWComposer, but there are a number of issues that need to be resolved. This will be a round-table discussion between Android developers and key upstream community members to discuss the limitations of KMS and possible solutions. Greg Hackmann will also discuss the Atomic Display Framework, which Android developers have recently created to try to work around the current limitations of KMS.

Finally, we’ll have a brief discussion on other proposed KMS extentions:

  • Non-memory-backed pipeline sources
  • Memory write-back
  • Chained composers
  • Non-linear pipelines (multiple encoders, …)
  • Root plane that doesn’t span the whole display
