91 * DC is the OS-agnostic component of the amdgpu DC driver.
93 * DC maintains and validates a set of structs representing the state of the
94 * driver and writes that state to AMD hardware
98 * struct dc - The central struct. One per driver. Created on driver load,
99 * destroyed on driver unload.
101 * struct dc_context - One per driver.
102 * Used as a backpointer by most other structs in dc.
104 * struct dc_link - One per connector (the physical DP, HDMI, miniDP, or eDP
105 * plugpoints). Created on driver load, destroyed on driver unload.
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)
112 * struct resource_pool - One per driver. Represents the hw blocks not in the
113 * main pipeline. Not directly accessible by dm.
115 * Main dc state structs:
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.
120 * struct dc_state - The global DC state to track global state information,
121 * such as bandwidth values.
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.
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.
129 * struct resource_context - Represents the programmable state of everything in
130 * the resource_pool. Not directly accessible by dm.
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).
