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).
