The format at the output of a subdev usually depends on the format at its input(s). The try format operation is thus not suitable for probing format at individual pads, as it can't modify the device state and thus can't remember the format tried at the input to compute the output format. To fix the problem, pass an extra argument to the get/set format operations to select the 'try' or 'active' format. The try format is used when probing the subdev. Setting the try format must not change the device configuration but can store data for later reuse. Data storage is provided at the file-handle level so applications probing the subdev concurently won't interfere with each other. The active format is used when configuring the subdev. It's identical to the format handled by the usual get/set operations.

The pipeline API helps drivers manage that information. When starting streaming, drivers call media_entity_pipeline_start(). The function marks all entities connected to the given entity through enabled links, either directly or indirectly, as streaming. Similarly, when stopping the stream, drivers call media_entity_pipeline_stop(). The media_entity_pipeline_start() function takes a pointer to a media pipeline and stores it in every entity in the graph. Drivers should embed the media_pipeline structure in higher-level pipeline structures and can then access the pipeline through the media_entity structure. Link configuration will fail with -EBUSY by default if either end of the link is a streaming entity, unless the link is marked with the MEDIA_LNK_FL_DYNAMIC flag.

In addition to enumerating and configuring subdevices, video camera drivers need a way to discover and modify at runtime how those subdevices are connected. This is done through new elements called entities, pads and links. 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. Links are stored in the source entity. To make backwards graph walk faster, a copy of all links is also stored in the sink entity. The copy is known as a backlink and is only used to help graph traversal. The entity API is made of three functions: - media_entity_init() initializes an entity. The caller must provide an array of pads as well as an estimated number of links. The links array is allocated dynamically and will be reallocated if it grows beyond the initial estimate. - media_entity_cleanup() frees resources allocated for an entity. It must be called during the cleanup phase after unregistering the entity and before freeing it. - media_entity_create_link() creates a link between two entities. An entry in the link array of each entity is allocated and stores pointers to source and sink pads. When a media device is unregistered, all its entities are unregistered automatically. The code is based on Hans Verkuil <hverkuil@xs4all.nl> initial work.

They were fixed, but the old ioctl names are still there, maintained to avoid breaking binary compatibility: There's no sense on preserving those forever, as it is very doubtful that someone would try to use a such old binary with a modern kernel. Removing them will allow us to remove some magic done at the V4L ioctl handler. Note that any application compiled with a videodev2.h from 2.6.7 or later will be using the correct ioctls.
