[RFC 7/7] android: Create comon header for IPC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This header contains IPC specific structures and code not related to
BT and audio HAL protocols. This allows to fully decouple IPC from
HAL messages.

This is first step to make HAL part of IPC unit-testable and reusable
between BT HAL and audio HAL.
