PRESENTATION_FEEDBACK_KIND_ZERO_COPY is a flag that needs to be set for each surface separately. Some surfaces may be zero-copy (as defined by Presentation feedback) while some are not. A complication with Weston is that a surface may have multiple views on screen. All copies (views) of the surface are required to be zero-copy for the ZERO_COPY flag to be set. Backends set per-view feedback flags during the assing_planes hook, and then Weston core collects the flags from all views of a surface.

Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for building weston and its dependencies. The test suite can be invoked via `make check`; see http://wayland.freedesktop.org/testing.html for additional details.
