Request for relevant source code files for extended & clone mode in display compositor

[appu s]

Dear All,

As I am a newbie to ChromeOS, earlier worked on linux DRM driver

As I have very high level or very basic level browser architecture level understanding , Hardware -> kernel DRM -> Ozone DRM -> Display Configurator -> Ozone DRM -> Kernel DRM -> Display Hardware

I am trying to understand the relevant  ie., the entry & exit points for browser related source code files -> when we switch between "Mirror & Extended" mode, could you please let me know the relevant browser related source code files for the same ie., relevant only for switching from "Clone to extended" & back viceversa in Display compositor component

Kindly do the needful

Many thanks in advance
