Lucas Tanure c8dcd16b01 ivi-layout-transition: Fix potential leak of memory pointed to by transition Several fixes to handle invalid transition objects: 1. Free transition in ivi_layout_transition_fade_layer if we fail to allocate memory for data 2. Check if transition is not null and if layout_transition_register was ok before return, if not, free transition 3. Destroy transition if layout_transition_register was not ok, we can't just free transition, we need to call layout_transition_destroy in order to free private_data from transition Signed-off-by: Lucas Tanure <tanure@linux.com> Reviewed-by: Bryce Harrington <bryce@osg.samsung.com>		2015-09-23 17:02:28 -07:00

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.
