drm/amd/display: Refactor virtual directory reorganize encoder and hwss files.

2026-02-12T20:08:49+00:00

[why] Virtual encoders & hwss were grouped in a separate directory, not aligned with dio and link component structure. [how] Moved virtual_link_encoder and virtual_stream_encoder to dc/dio/virtual/. Moved virtual_link_hwss to dc/link/hwss/ and renamed to link_hwss_virtual. Removed dc/virtual/ directory.

drm/amd/display: move panel replay out from edp

2026-01-10T19:21:52+00:00

[WHY] Panel Replay is not an eDP-specific function. [HOW] Create new Panel Replay source files and move the Panel Replay functions from the eDP files to the new files. Additionally, create a new link_service construct function to assign the related function pointers.

drm/amd/display: Support Compliance Test Pattern Generation with DP2 Retimer

2023-08-15T22:08:27+00:00

[WHY] Certain retimer requires workarounds in order to correctly output test patterns. [HOW] Add vendor-specific aux sequences to program retimer's TX and pattern generator when specific compliance test patterns are requested by sink.

drm/amd/display: break down dc_link.c

2023-02-08T22:15:51+00:00

[why] dc_link contains over 30k line of code, the decision is to break it down to files residing in link folder based on functionality. This change is the last break down change which will remove dc_link.c file after everything is broken down. [how] Move remaining dc_link.c functions into link_detection, link_dpms, link_validation, link_resource, and link_fpga and remove dc_link.

drm/amd/display: create accessories, hwss and protocols sub folders in link

2023-01-24T18:26:25+00:00

[why] link component contains three sub folders: accessories - utilities for improving testability, logging or tracing, doesn't impact end user use cases. protocols - specs defined protocols used in end user use cases hwss - hwss owned link_hwss object, served as an abstraction layer in hwss to access various types of encoder/phy/dpia endpoints in a unified interface. sooner we will have files directly under link folder one for the implementation of each major link behavior such as link_create, link_detect, link_validate and link_set_dpms.
