Description [wip] Ozone: Add GPU process side framework for external compositors. Hi, I am Robert Carr, and I am reaching out on behalf of the Mir team at Canonical. Recently I have been working on an Ozone-Mir implementation. This is not a suggestion to merge the attached branch, but at the suggestion of Robert Kroeger I am creating this issue on codereiew to centeralize discussion. A high level introduction is available on G+: https://plus.google.com/104358235952874475094/posts/cPmZofCRSA3 As expanded upon on Google+, Ozone-Mir is based off of the excellent work on Ozone-Wayland. Our initial study revealed there would be a huge amount of code duplication between a standalone Ozone Wayland and Ozone Mir, for the purpose of example, non exhaustive list: * Establishing/Managing Host/GPU Process Control Channel * Defining Window Management Protocol over Control Channel * Aura WindowTreeHost delegation etc… to build Ozone-Mir I have established a much smaller set of interfaces purely on the GPU process side which should be enough to implement an ozone backend for an external EGL compositor with linux style input (Wayland, Mir, X11?, SurfaceFlinger??). You can see the main interfaces https://github.com/racarr-ubuntu/ozone-mir/tree/master/ui/egl They are of course quite comparable to any other toolkit->windowing system abstraction layer. I expect Ozone-DRM and ChromeOS may have different requirements. For the purposes of Ozone Mir and Wayland though we would like to work to get the common components merged upstream under some ' ozone::EGL::WindowingSystem' kind of namespace, and the small GPU side interfaces exposed, so that Ozone Mir and Wayland to happily coexist without excessive duplication. To the Chromium and Ozone-Wayland maintainers: What are our steps going forward and how can we assist in preparing the code for upstream Chromium. If anyone would like to touch base off list, we can be reached in #ubuntu-mir on irc.freenode or mir-devel@lists.ubuntu.com Thanks, Robert Patch Set 1 : Dummy Patchset - See Github # Created: 6 years, 6 months ago [tar.bz2] Download [raw] Unified diffs Side-by-side diffs Delta from patch set Stats (+-1 lines, --1 lines) Patch A + dummy View 0 chunks +-1 lines, --1 lines 0 comments Download
