Hi Han, In ivi-shell architecture, there are controller plugins which controls the layout of surfaces on the display. The controller plugins are using ivi_layout_interface to do that. In weston repository, we have hmi-controller plugin which is good for demo purposes. But it is not suitable for production use-cases.
Please check https://github.com/GENIVI/wayland-ivi-extension. There, we have ivi-controller plugin which enables you to control the layout via ivi_wm protocol. You can use ivi-wm protocol directly in your Window Manager app, or you can use ilmControl library, or you can use LayerManagerControl command line tool to control the layout of surfaces.

Embedded, static-size display is a very different use case than a modern desktop system which requires hotplug and multimonitor layouts.

The traditional technique is to build your own Wayland compositor inside your application, which is a bit heavyweight, and then use wl_subsurface to composite the results. This is what e.g. WebKit2's architecture does, and it's something I've tried to implement in the past [0]. As the scope of a Wayland compositor becomes larger and larger over time, I think this is starting to become a bit impractical. It might be worth looking into a multi-process buffer-sharing protocol as a Wayland extension, since it's a use case that keeps coming up.

And GUI is act as a transparent top layer. All other process rendering by them self underneath. So its important for other process to place the window at right potion.

Currently i am creating a bigger surface bigger than screen size. and make subsurface so i can posion them as i want. Really don't think its a good way to do it.

However, for embedded cases, there are protocols like ivi-shell which provide that functionality.
