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