For PHY related programming, see the Video PHY Controller LogiCORE IP Product Guide (PG230).
The DisplayPort RX Subsystem is delivered with a bare-metal driver and API designed to handle all programming of the subsystem core. The driver is automatically available in the Vitis™ tools when a project is created from an XSA file that includes the DisplayPort RX Subsystem. This bare-metal driver can also be seen on the Xilinx GitHub. See API Documentation for more information. Linux drivers are also available. See the Xilinx Wiki page for more information.
