Introducing AMDGPU Composition Stack (ACS).
ACS is simply AMD's fork of Weston compositor, with some additional advanced features. We have created ACS considering the following primary goals in mind:

  *   To act as a staging area for Wayland features to be open-sourced to mainline Weston project.
  *   To act as a reference compositor for AMD's advanced graphics and display feature development.
  *   To provide a middleware compositor which extracts the best out of AMD Display and Graphics HW (We don't mind being biased to AMDGPU HW 🙂)
     *   To host some of the AMD HW specific code, which can't be merged in Weston mainline due to its bias towards AMD HW.
  *   To be utilised in full stack opensource delivery vehicle for AMDs commercial solutions and products.
  *
To be the space where AMD specific in-house SW tools (performance tweakers, multimedia players, 3D games, profiling tools etc) can be saved in future.

ACS project is hosted here:

A detailed wiki of introduction to ACS, its features and feature roadmap can be found here:

The details about additional features implemented in ACS are documented here:

PS: We are yet to deploy a CI/CD build for ACS project.
