Implement the Android hwcomposer HAL over KMS
The number of ARM SoC (and other) platforms supporting the KMS API is steadily growing. However, the SoC vendor is still in a position of supporting multiple sets of interfaces when integrating Android in addition to other Linux-based platforms as Android also has its own set of HALs. We will implement the hwcomposer HAL using KMS, which will give anyone with a KMS implementation a ready hwcomposer implementation.
