This section is intended to elaborate on and act as a companion to the link training procedure in the VESA DisplayPort Standard v1.4.

Xilinx® advises all users of the source core to use an Arm® processor, a MicroBlaze™ processor or similar embedded processor to properly initialize and maintain the link. The tasks encompassed in the Link and Stream Policy Makers are likely too complicated to be efficiently managed by a hardware-based state machine. Xilinx does not recommend using the RTL based controllers, and such controllers are not supported through the service portal.
