This feature is addressed via special domains: EarlyDomains. These domains are acting "unmanaged" - meaning without the interaction with the +AudioManager - providing a simpler set of features until the AudioManager is up and running. When the Linux system is then fully operable a handover is done +from the EarlyDomains towards the AudioManager. In order to be able to operate without the Linux up and running, the EarlyDomains must be implemented on a +second fast-boot or always-on controller, e.g. the so called vehicle processor.\n +\section earlys Early Startup +This picture shows the principle of the early startup: +\image html early.png +\section late Late Rundown +This picture shows the principle of the late rundown: +\image html late.png +*/
