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