 ==== Overview ==== ==== Overview ====
 We are developing the Best Freakin'​ Home Screen Ever for release with version 1 of the AGL distribution. ​ We are developing the Best Freakin'​ Home Screen Ever for release with version 1 of the AGL distribution. ​
 +
 +This project is covered by [[https://​jira.automotivelinux.org/​browse/​SPEC-24?​filter=10100 | Jira issue SPEC-24]] and its substasks.
  
 ==== Requirements ==== ==== Requirements ====
-Requirements for the Home Screen application are based on the [[:​agl_specification|AGL Requirements Specification]]. The team pulled the requirements from the spec and determined which requirements are to be met during this development cycle (through the end 2015). That list of requirements is {{:​agl-distro:​demo-apps:​agl_spec_homescreen_rev01.pdf|here}}.+Requirements for the Home Screen application are based on the [[:​agl_specification|AGL Requirements Specification ​ver 1.0]].  
 + 
 +**//Summary of Home Screen Requirements//​** 
 +  * Customize GUI layout by each vehicle, grade, brand and so on. 
 +  * Display status notifications,​ pop-up window, system setting, software keyboard for ivi-use. 
 +  * Manage applications (menu screen, kick applications launcher, install applications) 
 +  * Switch applications ( application stack, last application)

 +**//​Comparing ivi-shell to desktop-shell//​**
 +
 +A shell consists of two components.
 +  * Plugin: provided as the weston plugin
 +  * Daemon: GUI for the system.
 +Weston provides two type of plugins.
 +  * desktop-shell:​ for PC use sample.
 +  * ivi-shell: for ivi use provided by GENIVI.
 +
 +|          ^ desktop-shell ​ ^ ivi-shell ​                 ^
 +^ Plug-in ​ | Standard APIs              | APIs for ivi-applications ​ |
 +^:::       | APIs for desktop creation ​ | APIs for HMI control daemon|
 +^:::       ​| ​                           | Layer control functions ​   |
 +^ daemon ​  | GUI Design ​                | GUI Design ​                |
 +^:::       | Application Launcher ​      | Application Launcher ​      |
 +^:::       ​| ​                           | Layout, layer definition ​  |
 +
 +**Tizen Wiki**([[https://​wiki.tizen.org/​wiki/​IVI-Shell]])\\
 +IVI-Shell does not support "​wl_shell"​ nor "​xdg-shell"​ (the "​desktop"​ shell protocols found in upstream Weston) but a totally different one, named "​ivi-application"​.
 +This means that standard Wayland clients cannot be displayed on IVI-Shell, unless they somehow use the IVI-Shell protocol. The package itself provides demo clients, but incompatible clients are more common.\\
 +
 +Which plugin should AGL homescreen use?
 +  * Opt.1: re-use ivi-shell
 +{{:​agl-distro:​demo-apps:​option1.png?​300|}}
 +
 +  * Opt.2: create a new shell for AGL
 +{{:​agl-distro:​demo-apps:​option2.png?​300|}}
 +
 +
 +|          ^ Pros                        ^ Cons                       ^
 +^ Option 1 | ivi-shell upstream already ​ | Standard API Support needs to be added        |
 +^:::       | Layer functionality available ​ | APIs for HMI control daemon ​               |
 +^ Option 2 | Standard API support available | Need to create new software ​               |
 +^:::       ​| ​                               | Layer functionality needs to be designed ​  |
 +
 +The team prefers to reuse ivi-shell (option 1) assuming the maintainer supports AGL changes. ​
 +  * Support standard APIs
 +  * Maintain and support AGL requirements
