[weston-ivi-shell]Qestion about caller of [bind_shell] and [shell_get_shell_surface ]

[Yang Andy]

Hi everyone

I am testing QT/EFL application launch time from ICO-HomeScreen at tizenIVI platform,but the launch time is about 4 seconds.

I analyze the NG log,and find result as below:

(a) When QT application is laundch by AUL module,until the function [bind_shell] of weston-ivi-shell module is called,consumption time is 1 second.(Below step:2-->3)
(b) Until the function [shell_get_shell_surface ] of weston-ivi-shell module is called,consumption time is 1.5 second.(Below step:3-->4)

So i think the point is to find the caller of function [bind_shell] and [shell_get_shell_surface ].

I have two question for help,any answer is appreciate.

Qeustion1:Are 「bind_shell」 and 「shell_get_shell_surface」 called by ＱＴ−Ｗａｙｌａｎｄ?
（I search source of ＱＴ−Ｗａｙｌａｎｄ,but i did not find the right one）

Qestion2:Do contents/screen rendering sequence as below??
 
　Ａ）　ＱＴ−Ｗａｙｌａｎｄ module create ＷＬ−Ｓｕｒｆａｃｅ.
　Ｂ）　ＱＴ−Ｗａｙｌａｎｄ create contents on ＷＬ−Ｓｕｒｆａｃｅ.
　Ｃ）　ＱＴ−Ｗａｙｌａｎｄ send request to ＩＶＩ−Ｓｈｅｌｌ for creating ＩＶＩ−Ｓｕｒｆａｃｅ（At this timing,i think that bind_shell and shell_get_shell_surface is called??）
　Ｄ）　ＩＶＩ−Ｓｈｅｌｌ／ＩＶＩ−Ｃｏｎｔｒｏｌｌｅｒ create ＩＶＩ−Ｓｕｒｆａｃｅ,and send request toＩＣＯ−Ｈｏｍｅ for creaing Windows.
　Ｅ）　ＩＣＯ−Ｈｏｍｅ useＩＶＩ−Ｃｏｎｔｒｏｌｌｅｒ to request sreen composition. 

Could anyone give me some advice?
