  88  * DOC: Overview
  89  *
  90  * DC is the OS-agnostic component of the amdgpu DC driver.
  91  *
  92  * DC maintains and validates a set of structs representing the state of the
  93  * driver and writes that state to AMD hardware
  94  *
  95  * Main DC HW structs:
  96  *
  97  * struct dc - The central struct.  One per driver.  Created on driver load,
  98  * destroyed on driver unload.
  99  *
 100  * struct dc_context - One per driver.
 101  * Used as a backpointer by most other structs in dc.
 102  *
 103  * struct dc_link - One per connector (the physical DP, HDMI, miniDP, or eDP
 104  * plugpoints).  Created on driver load, destroyed on driver unload.
 105  *
 106  * struct dc_sink - One per display.  Created on boot or hotplug.
 107  * Destroyed on shutdown or hotunplug.  A dc_link can have a local sink
 108  * (the display directly attached).  It may also have one or more remote
 109  * sinks (in the Multi-Stream Transport case)
 110  *
 111  * struct resource_pool - One per driver.  Represents the hw blocks not in the
 112  * main pipeline.  Not directly accessible by dm.
 113  *
 114  * Main dc state structs:
 115  *
 116  * These structs can be created and destroyed as needed.  There is a full set of
 117  * these structs in dc->current_state representing the currently programmed state.
 118  *
 119  * struct dc_state - The global DC state to track global state information,
 120  * such as bandwidth values.
 121  *
 122  * struct dc_stream_state - Represents the hw configuration for the pipeline from
 123  * a framebuffer to a display.  Maps one-to-one with dc_sink.
 124  *
 125  * struct dc_plane_state - Represents a framebuffer.  Each stream has at least one,
 126  * and may have more in the Multi-Plane Overlay case.
 127  *
 128  * struct resource_context - Represents the programmable state of everything in
 129  * the resource_pool.  Not directly accessible by dm.
 130  *
 131  * struct pipe_ctx - A member of struct resource_context.  Represents the
 132  * internal hardware pipeline components.  Each dc_plane_state has either
 133  * one or two (in the pipe-split case).
