if the layer is in order of some screen we need to remove it from there and mark the screen order as dirty so it will be removed in commit_screen_list call later layer should only be assigned to one screen at a time Signed-off-by: Eugen Friedrich <efriedrich@de.adit-jv.com> Signed-off-by: Emre Ucan <eucan@de.adit-jv.com> Reviewed-by: Pekka Paalanen <pekka.paalanen@collabora.co.uk> |

In-vehicle infotainment (information and entertainment) graphical environment support modules for Weston IVI-shell is an alternative shell for Weston, a Wayland display server. Window management and application interaction with the display server are very different to that of a normal desktop, which is why this is a separate shell and not an extension to the desktop-shell suite with xdg_shell. As such, applications need to be specifically written to use IVI-shell. IVI-shell contains two main features: - Common layout library for surface, which allow ivi-shell developer to develop own shell, linking Common layout library. For the time being, the library refers Genivi ilm interface. http://projects.genivi.org/wayland-ivi-extension/ - Extension protocol; ivi-application to tie wl_surface and a given ID. With this ID, shell can identify which wl_surface is drawn by which application. In in-vehicle infortainment system, a shell has to update a property of a wl_surface. E.g. there may be a use case when vehicle starts to move, the wl_surface drawn by Car navigation is expected to move top of surfaces. The actual software components delivered with Weston are: - ivi-application.xml: Wayland protocol extension for IVI-applications; the public shell protocol (the same concept as xdg_shell). Implemented by ivi-shell.so. - ivi-shell.so: A Weston shell module that implements ivi-application.xml interfaces. Loads ivi-layout.so. - ivi-layout.so: Implements the IVI window management concepts: Screen, Layer, Surface, groups of Layers, groups of Surfaces, see: http://projects.genivi.org/ivi-layer-management/node/13 Offers a stable API for writing IVI-controller modules like hmi-controller.so against the IVI concepts. In other words, it offers an API to write IVI window manager modules. - hmi-controller.so: A sample implementation of an IVI-controller module, usually replaced by IVI system vendors. Uses ivi-layout.so to perform essentially window manager tasks. This implementation keeps all window management inside the module, while IVI-systems may use another module that exposes all window management via Wayland or other protocol for an external process to control: http://git.projects.genivi.org/?p=wayland-ivi-extension.git;a=summary - ivi-hmi-controller.xml: Wayland protocol extension for IVI display control; the private shell protocol for weston-ivi-shell-user-interface client (the same concept as desktop-shell.xml). Implemented by hmi-controller.so, and usually replaced by IVI system vendors. - weston-ivi-shell-user-interface: A sample implementation of an IVI shell helper client, usually replaced by IVI system vendors. A helper client for basic display content, similar to weston-desktop-shell. How to compile: same as weston. To disable, use option: --disable-ivi-shell for configure. How to configure weston.ini: reference ini file will be generated in <build_dir>/ivi-shell. How to run: same as weston. exec weston.
