drm/amd/display: move public dc link function implementation to dc_link_exports

2023-02-14T21:06:28+00:00

[why] Link is a subcomponent in dc. DM should be aware of dc link structure as one of the abstracted objects maintained by dc. However it should have no idea of the existence of a link component in dc dedicated to maintain the states of dc link structure. As such we are moving link interfaces out of dc_link.h and directly added to dc.h. We are grandually fading out the explicit inclusion of dc_link header and eventually delete it. On dc side, since link is a subcomponent behind dc interfaces, it is not a good idea to implement dc interfaces in each individual subcomponent of link which is already a subcomponent of dc. So we are decoupling it by implementing a dc_link_exports in dc. This file will be a thin translation layer that breaks the dependency so link is able to make interface changes without breaking DM.

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.

[Why] linux amdgpu defer handle link lost irq. dm add handle request to irq work queue for the first irq of link lost. if link training fails for link lost handle, link will not be enabled anymore. [How] allow adding handle request of link lost to work queue before running dp link training for link lost.
