The HDMI 2.1 RX Subsystem driver abstracts the included supporting elements and provides you with an API for control. The API can be easily integrated into your application thereby providing an out-of-the-box solution.
The subsystem driver is a bare-metal driver, which provides an abstracted view of the feature set provided by each sub-core. It dynamically manages the data and control flow through the processing elements, based on the input/output stream configuration set at run time. Internally, it relies on sub-core drivers to configure the sub-core IP blocks.
