drm/amd/display: Add structs for Freesync Panel Replay

2023-08-07T21:12:49Z

In some instances, the GPU is transmitting repeated frame to the sink without any updates or changes in the content. These repeat transmission are wasteful, resulting in power draw in different aspects of the system 1. DCN is fetching the frame of data from DF/UMC/DRAM. This memory traffic prevents power down of parts of this HW path. 2. GPU is transmitting pixel data to the display through the main link of the DisplayPort interface. This prevents power down of both the Source transmitter (TX) and the Sink receiver (RX) The concepts of utilizing replay is similar to PSR, but there is a benefit of: Source and Sink remaining synchronized which allows for - lower latency when switching from replay to live frames - enable the possibility of more use cases - easy control of the sink's refresh rate during replay Due to Source and Sink remaining timing synchronized, Replay can be activated in more UI scenarios.
