This document focus + * on the kernel-side implementation of the media framework. + * + * * Abstract media device model: + * + * Discovering a device internal topology, and configuring it at runtime, is one + * of the goals of the media framework. To achieve this, hardware devices are + * modelled as an oriented graph of building blocks called entities connected + * through pads. + * + * An entity is a basic media hardware building block. It can correspond to + * a large variety of logical blocks such as physical hardware devices + * (CMOS sensor for instance), logical hardware devices (a building block + * in a System-on-Chip image processing pipeline), DMA channels or physical + * connectors. + * + * A pad is a connection endpoint through which an entity can interact with + * other entities. Data (not restricted to video) produced by an entity + * flows from the entity's output to one or more entity inputs. Pads should + * not be confused with physical pins at chip boundaries. + * + * A link is a point-to-point oriented connection between two pads, either + * on the same entity or on different entities. Data flows from a source + * pad to a sink pad. + * + * + * * Media device: + * + * A media device is represented by a struct &media_device instance, defined in + * include/media/media-device.h. Allocation of the structure is handled by the + * media device driver, usually by embedding the &media_device instance in a + * larger driver-specific structure. + * + * Drivers register media device instances by calling + * __media_device_register() via the macro media_device_register() + * and unregistered by calling + * media_device_unregister(). + * + * * Entities, pads and links: + * + * - Entities + * + * Entities are represented by a struct &media_entity instance, defined in + * include/media/media-entity.h. The structure is usually embedded into a + * higher-level structure, such as a v4l2_subdev or video_device instance, + * although drivers can allocate entities directly. + * + * Drivers initialize entity pads by calling + * media_entity_pads_init(). + * + * Drivers register entities with a media device by calling + * media_device_register_entity() + * and unregistred by calling + * media_device_unregister_entity(). + * + * - Interfaces + * + * Interfaces are represented by a struct &media_interface instance, defined in + * include/media/media-entity.h. Currently, only one type of interface is + * defined: a device node. Such interfaces are represented by a struct + * &media_intf_devnode. + * + * Drivers initialize and create device node interfaces by calling + * media_devnode_create() + * and remove them by calling: + * media_devnode_remove(). + * + * - Pads + * + * Pads are represented by a struct &media_pad instance, defined in + * include/media/media-entity.h. Each entity stores its pads in a pads array + * managed by the entity driver. Drivers usually embed the array in a + * driver-specific structure. + * + * Pads are identified by their entity and their 0-based index in the pads + * array. + * Both information are stored in the &media_pad structure, making the + * &media_pad pointer the canonical way to store and pass link references. + * + * Pads have flags that describe the pad capabilities and state. + * + * %MEDIA_PAD_FL_SINK indicates that the pad supports sinking data. + * %MEDIA_PAD_FL_SOURCE indicates that the pad supports sourcing data. + * + * NOTE: One and only one of %MEDIA_PAD_FL_SINK and %MEDIA_PAD_FL_SOURCE must + * be set for each pad. + * + * - Links + * + * Links are represented by a struct &media_link instance, defined in + * include/media/media-entity.h. There are two types of links: + * + * 1. pad to pad links: + * + * Associate two entities via their PADs. Each entity has a list that points + * to all links originating at or targeting any of its pads. + * A given link is thus stored twice, once in the source entity and once in + * the target entity. + * + * Drivers create pad to pad links by calling: + * media_create_pad_link() and remove with media_entity_remove_links(). + * + * 2. interface to entity links: + * + * Associate one interface to a Link. + * + * Drivers create interface to entity links by calling: + * media_create_intf_link() and remove with media_remove_intf_links(). + * + * NOTE: + * + * Links can only be created after having both ends already created. + * + * Links have flags that describe the link capabilities and state. The + * valid values are described at media_create_pad_link() and + * media_create_intf_link(). + * + * Graph traversal: + * + * The media framework provides APIs to iterate over entities in a graph. + * + * To iterate over all entities belonging to a media device, drivers can use + * the media_device_for_each_entity macro, defined in + * include/media/media-device.h. + * + * struct media_entity *entity; + * + * media_device_for_each_entity(entity, mdev) { + * // entity will point to each entity in turn + * ... + * } + * + * Drivers might also need to iterate over all entities in a graph that can be + * reached only through enabled links starting at a given entity. The media + * framework provides a depth-first graph traversal API for that purpose. + * + * Note that graphs with cycles (whether directed or undirected) are *NOT* + * supported by the graph traversal API. To prevent infinite loops, the graph + * traversal code limits the maximum depth to MEDIA_ENTITY_ENUM_MAX_DEPTH, + * currently defined as 16. + * + * Drivers initiate a graph traversal by calling + * media_entity_graph_walk_start() + * + * The graph structure, provided by the caller, is initialized to start graph + * traversal at the given entity. + * + * Drivers can then retrieve the next entity by calling + * media_entity_graph_walk_next() + * + * When the graph traversal is complete the function will return NULL. + * + * Graph traversal can be interrupted at any moment. No cleanup function call + * is required and the graph structure can be freed normally. + * + * Helper functions can be used to find a link between two given pads, or a pad + * connected to another pad through an enabled link + * media_entity_find_link() and media_entity_remote_pad() + * + * Use count and power handling: + * + * Due to the wide differences between drivers regarding power management + * needs, the media controller does not implement power management. However, + * the &media_entity structure includes a use_count field that media drivers + * can use to track the number of users of every entity for power management + * needs. + * + * The &media_entity.@use_count field is owned by media drivers and must not be + * touched by entity drivers. Access to the field must be protected by the + * &media_device.@graph_mutex lock. + * + * Links setup: + * + * Link properties can be modified at runtime by calling + * media_entity_setup_link() + * + * Pipelines and media streams: + * + * When starting streaming, drivers must notify all entities in the pipeline to + * prevent link states from being modified during streaming by calling + * media_entity_pipeline_start(). + * + * The function will mark all entities connected to the given entity through + * enabled links, either directly or indirectly, as streaming. + * + * The &media_pipeline instance pointed to by the pipe argument will be stored + * in every entity in the pipeline. Drivers should embed the &media_pipeline + * structure in higher-level pipeline structures and can then access the + * pipeline through the &media_entity pipe field. + * + * Calls to media_entity_pipeline_start() can be nested. The pipeline pointer + * must be identical for all nested calls to the function. + * + * media_entity_pipeline_start() may return an error. In that case, it will + * clean up any of the changes it did by itself. + * + * When stopping the stream, drivers must notify the entities with + * media_entity_pipeline_stop(). + * + * If multiple calls to media_entity_pipeline_start() have been made the same + * number of media_entity_pipeline_stop() calls are required to stop streaming. + * The &media_entity pipe field is reset to NULL on the last nested stop call. + * + * Link configuration will fail with -%EBUSY by default if either end of the + * link is a streaming entity. Links that can be modified while streaming must + * be marked with the %MEDIA_LNK_FL_DYNAMIC flag. + * + * If other operations need to be disallowed on streaming entities (such as + * changing entities configuration parameters) drivers can explicitly check the + * media_entity stream_count field to find out if an entity is streaming. This + * operation must be done with the media_device graph_mutex held. + * + * Link validation: + * + * Link validation is performed by media_entity_pipeline_start() for any + * entity which has sink pads in the pipeline. The + * &media_entity.@link_validate() callback is used for that purpose. In + * @link_validate() callback, entity driver should check that the properties of + * the source pad of the connected entity and its own sink pad match. It is up + * to the type of the entity (and in the end, the properties of the hardware) + * what matching actually means. + * + * Subsystems should facilitate link validation by providing subsystem specific + * helper functions to provide easy access for commonly needed information, and + * in the end provide a way to use driver-specific callbacks. + */ + +struct ida; struct device; /** @@ -41,8 +273,16 @@ struct device; * @bus_info: Unique and stable device location identifier * @hw_revision: Hardware device revision * @driver_version: Device driver version - * @entity_id: ID of the next entity to be registered + * @topology_version: Monotonic counter for storing the version of the graph + * topology.
