89/**
* DOC: Overview
*
* DC is the OS-agnostic component of the amdgpu DC driver.
*
* DC maintains and validates a set of structs representing the state of the
* driver and writes that state to AMD hardware
*
* Main DC HW structs:
*
* struct dc - The central struct.  One per driver.  Created on driver load,
* destroyed on driver unload.
*
* struct dc_context - One per driver.
* Used as a backpointer by most other structs in dc.
*
* struct dc_link - One per connector (the physical DP, HDMI, miniDP, or eDP
* plugpoints).  Created on driver load, destroyed on driver unload.
*
* struct dc_sink - One per display.  Created on boot or hotplug.
* Destroyed on shutdown or hotunplug.  A dc_link can have a local sink
* (the display directly attached).  It may also have one or more remote
* sinks (in the Multi-Stream Transport case)
*
* struct resource_pool - One per driver.  Represents the hw blocks not in the
* main pipeline.  Not directly accessible by dm.
*
* Main dc state structs:
*
* These structs can be created and destroyed as needed.  There is a full set of
* these structs in dc->current_state representing the currently programmed state.
*
* struct dc_state - The global DC state to track global state information,
* such as bandwidth values.
*
* struct dc_stream_state - Represents the hw configuration for the pipeline from
* a framebuffer to a display.  Maps one-to-one with dc_sink.
*
* struct dc_plane_state - Represents a framebuffer.  Each stream has at least one,
* and may have more in the Multi-Plane Overlay case.
*
* struct resource_context - Represents the programmable state of everything in
* the resource_pool.  Not directly accessible by dm.
*
* struct pipe_ctx - A member of struct resource_context.  Represents the
* internal hardware pipeline components.  Each dc_plane_state has either
* one or two (in the pipe-split case).
