Weston IVI-shell |
||||
================ |
||||
|
||||
Weston's IVI-shell is a highly customizable shell targeted at use cases which |
||||
need custom control over the shell's window layout with one or more applications |
||||
without interactive configuration of the layout by the user. |
||||
|
||||
Example use cases for the IVI-shell are IVI applications or industrial human |
||||
machine interfaces. In general, whenever the user interface requires the exact |
||||
positioning of multiple application surfaces on one or more screens. |
||||
|
||||
The IVI-shell also provides a means for applications to identify themselves to |
||||
the shell by application IDs via the ivi_application Wayland protocol. |
||||
|
||||
IVI-shell client protocol |
||||
------------------------- |
||||
|
||||
Wayland clients can implement the ``ivi_application`` Wayland protocol, which |
||||
allows them to specify an ``ivi_id`` to allow the IVI controller to identify the |
||||
application. This allows the controller to implement special behavior for |
||||
well-known applications. |
||||
|
||||
The IVI-shell is able to also handle clients that use the ``xdg-shell`` |
||||
protocol, but in these cases the IVI-shell needs other means to identify client |
||||
applications. |
||||
|
||||
See ``ivi-application.xml`` for the protocol specification. |
||||
|
||||
IVI-shell Weston modules |
||||
------------------------ |
||||
|
||||
The IVI-shell consists of two main components: The ``ivi-shell.so`` and custom |
||||
IVI controller (with the ``hmi-controller.so`` example implementation). |
||||
|
||||
The ``ivi-shell.so`` is responsible for handling the application IDs and for |
||||
providing abstractions to configure the window layout via the |
||||
``ivi_layout_interface``. This interface is discussed in `IVI-shell compositor |
||||
implementation`. |
||||
|
||||
The IVI controller uses the ``ivi_layout_interface`` to implement a window |
||||
manager and is responsible for configuring the window layout, i.e. the position |
||||
of the applications on the screens. |
||||
|
||||
Due to this separation, both modules must be loaded in your ``weston.ini`` to |
||||
use the IVI-shell. |
||||
|
||||
.. code-block:: ini |
||||
|
||||
[core] |
||||
shell=ivi-shell.so |
||||
modules=hmi-controller.so |
||||
|
||||
If you are using your custom controller, replace ``hmi-controller.so`` with the |
||||
name of your own controller module. |
||||
|
||||
.. figure:: images/ivi-shell.png |
||||
:alt: IVI-shell architecture overview |
||||
|
||||
Controlling the IVI-shell |
||||
------------------------- |
||||
|
||||
The IVI-shell provides the ``ivi_layout_interface`` API that a controller must |
||||
use to control the window layout of the IVI-shell. See |
||||
``ivi-shell/ivi-layout-export.h`` for the definition of this API. |
||||
|
||||
For the initial configuration, the controller has to create at least one |
||||
``ivi_layout_layer`` and add the ``ivi_layout_layer`` to a ``weston_output``. |
||||
The layers allow to group multiple applications surfaces and control them |
||||
together and are the main mechanism to group and organize surfaces. These are |
||||
always necessary to show something using the IVI-shell. The IVI-shell will |
||||
internally create an ``ivi_layout_screen``, but a controller always uses the |
||||
``weston_output`` directly. |
||||
|
||||
To get control over the client surfaces, the controller must use notifiers that |
||||
trigger whenever there are changes to the client surfaces. The client surfaces |
||||
then show up as ``ivi_layout_surface``. These have an ID, which allows the |
||||
controller to identify the surface and reconfigure the window layout |
||||
accordingly. |
||||
|
||||
The controller must add the ``ivi_layout_surface`` to an ``ivi_layout_layer`` |
||||
and configure it's position and z-order wrt. the other surfaces in the layer. |
||||
Otherwise, the newly added surface will not show up on the screen. |
||||
|
||||
The IVI-shell will internally create an ``ivi_layout_view`` for each layer that |
||||
the surface was added to. However, the views are not provided to the IVI |
||||
controller. |
||||
|
||||
After configuring all expected changes, the controller must call the |
||||
``commit_changes`` to atomically update the display layout. |
||||
|
||||
IVI-shell example implementation |
||||
-------------------------------- |
||||
|
||||
The IVI-shell comes with an example implementation of an IVI controller -- the |
||||
`hmi-controller`. The hmi-controller will usually replaced by a custom |
||||
implementation that implements the use-case-specific behavior. |
||||
|
||||
The hmi-controller is split into two parts: |
||||
|
||||
The ``hmi-controller.so`` is a Weston Plugin that uses the |
||||
``ivi_layout_interface`` to perform the window manager tasks. It allows some |
||||
reconfiguration of the window layout via the ``ivi_hmi_controller`` protocol. |
||||
Other implementations may keep all window management inside the module or may |
||||
expose even more window management via a custom protocol to an external process. |
||||
|
||||
The ``weston-ivi-shell-user-interface`` is an example hmi-controller helper |
||||
client that serves as a user interface for controlling the hmi-controller. |
||||
|
||||
The hmi-controller can be customized using the ``[ivi-shell]`` section in the |
||||
``weston.ini``. An example configuration will be generated in |
||||
``<build_dir>/ivi-shell/weston.ini``. |

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. |
||||
|
||||
https://at.projects.genivi.org/wiki/display/WIE/Wayland+IVI+Extension+Home |
||||
|
||||
- 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: |
||||
https://at.projects.genivi.org/wiki/display/WIE/Summary+of+Layer+manager+APIs |
||||
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. |
||||
|
||||
- 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. |
||||
|
||||
