This wiki page (and any sub-pages) are to be used to document progress on a Metal rendering pipeline for OS and as a collaboration medium for the OpenJDK developers working it, as a better alternative than private emails or .
The Metal pipeline work is not a formal OpenJDK project, but is being guided by the 2d group. A JEP is not yet drafted or submitted but one is likely once we move past the prototyping stage and this wiki will be updated to reflect that.
By continuing separately we are creating technical debt and not making efficient use of resources. The intent is that after some small amount of additional prototyping to merge the work into the OpenJDK sandbox and collaborate there to satisfy the goals set out above. The development process will however continue to be relatively informal for some time to come. We aren't expecting to use bug ids for reviews or pushes into the sandbox, at least for now. When code reviews will be required is yet to be determined.
