* [media] media.h: create connector entities for hybrid TV devicesMauro Carvalho Chehab2016-01-111-2/+10
| | | | | | | | Add entities to represent the connectors that exists inside a hybrid TV device. Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] media-entity.h: document all the structsMauro Carvalho Chehab2016-01-111-30/+84
| | | | | | | | | | | | Only a few structs are documented on kernel-doc-nano format (the ones added by the MC next gen patches). Add a documentation for all structs, and ensure that they'll be producing the documentation at the Kernel's device driver DocBook.

* [media] v4l2-core: create MC interfaces for devnodesMauro Carvalho Chehab2016-01-113-19/+109
| | | | | | | | | | | V4L2 device (and subdevice) nodes should create an interface, if the Media Controller support is enabled. Please notice that radio devices should not create an entity, as radio input/output is either via wires or via ALSA.

* [media] dvbdev: returns error if graph object creation failsMauro Carvalho Chehab2016-01-113-137/+193
| | | | | | | | | | | | | | | | | | | | | Right now, if something gets wrong at dvb_create_media_entity() or at dvb_create_media_graph(), the device will still be registered. Change the logic to properly handle it and free all media graph objects if something goes wrong at dvb_register_device(). Also, change the logic at dvb_create_media_graph() to return an error code if something goes wrong. It is up to the caller to implement the right logic and to call dvb_unregister_device() to unregister the already-created objects. While here, add a missing logic to unregister the created interfaces. Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] media-entity: fix backlink removal on __media_entity_remove_link()Mauro Carvalho Chehab2016-01-111-3/+3
| | | | | | | | | The logic is testing if num_links==0 at the wrong place. Due to that, a backlink may be kept without removal, causing KASAN to complain about usage after free during either entity or link removal. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] media: don't try to empty links list in media_entity_cleanup()Javier Martinez Canillas2016-01-111-7/+0Star
| | | | | | | | | | | | | | | | The media_entity_cleanup() function only cleans up the entity links list but this operation is already made in media_device_unregister_entity(). In most cases this should be harmless (besides having duplicated code) since the links list would be empty so the iteration would not happen but the links list is initialized in media_device_register_entity() so if a driver fails to register an entity with a media device and clean up the entity in the error path, a NULL deference pointer error will happen. So don't try to empty the links list in media_entity_cleanup() since is either done already or haven't been initialized yet. Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com>
* [media] au0828: postpone call to au0828_unregister_media_device()Mauro Carvalho Chehab2016-01-111-2/+4
| | | | | | | | | The DVB core needs to unregister the media device. So, we can't call au0828_unregister_media_device() before calling au0828_dvb_unregister(), otherwise the DVB MC free code (that will be implemented on the next patch) will fail.

* [media] dvbdev: enable all interface links at initMauro Carvalho Chehab2016-01-111-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Interface links are normally enabled, meaning that the interfaces are bound to the entities. So, any ioctl sent to the interface are reflected at the entities managed by the interface. However, when a device is in use, other interfaces for the same hardware could be decoupled from the entities linked to them, because the hardware may have some parts busy. That's for example, what happens when an hybrid TV device is in use. If it is streaming analog TV or capturing signals from S-Video/Composite connectors, typically the digital part of the hardware can't be used and vice-versa. This is generally due to some internal hardware or firmware limitation, that it is not easily mapped via data pipelines. What the Kernel drivers do internally is that they decouple the hardware from the interface. So, all changes, if allowed, are done only at some interface cache, but not physically changed at the hardware. The usage is similar to the usage of the MEDIA_LNK_FL_ENABLED on data links. So, let's use the same flag to indicate if either the interface to entity link is bound/enabled or not.

* [media] media-entity: protect object creation/removal using spin lockMauro Carvalho Chehab2016-01-112-9/+9
| | | | | | | | | | | | | | | Some parts of the media controller are using mutexes while others are using spin locks in order to protect creation and removal of elements in the graph. That's wrong! Also, the V4L2 core can remove graph elements on non-interactive context: BUG: sleeping function called from invalid context at include/linux/sched.h:2776 Fix it by always using spin locks for graph element addition/removal, just like entity creation/removal is protected at media-device.c Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* [media] media-device: add pads and links to media_deviceMauro Carvalho Chehab2016-01-113-11/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MC next gen API sends objects to userspace grouped by their types. In the case of pads and links, in order to improve performance and have a simpler code, the best is to store them also on separate linked lists at MC. If we don't do that, we would need this kind of interaction to send data to userspace (code is in structured english): for each entity: for each pad: store pads for each entity: for each link: store link for each interface: for each link: store link With would require one nested loop for pads and two nested loops for links. By using separate linked lists for them, just one loop would be enough. Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

Please note that most drivers assume that there's just AV_DMA or V4L2 subdevs. This is not true anymore, as we've added MC support for DVB, and there are plans to add support for ALSA and FB/DRM too. Ok, on the current pipelines supported by those drivers, just V4L stuff are there, but, assuming that some day a pipeline that also works with other subsystems will ever added, it is better to add explicit checks for the AV_DMA stuff.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The entire logic that represent graph links were developed on a time where there were no needs to dynamic remove links. So, although links are created/removed one by one via some functions, they're stored as an array inside the entity struct. As the array may grow, there's a logic inside the code that checks if the amount of space is not enough to store the needed links. If it isn't the core uses krealloc() to change the size of the link, with is bad, as it leaves the memory fragmented. So, convert links into a list. Also, currently, both source and sink entities need the link at the graph traversal logic inside media_entity. So there's a logic duplicating all links. That makes it to spend twice the memory needed. This is not a big deal for today's usage, where the number of links are not big. Yet, if during the MC workshop discussions, it was said that IIO graphs could have up to 4,000 entities. So, we may want to remove the duplication on some future. The problem is that it would require a separate linked list to store the backlinks inside the entity, or to use a more complex algorithm to do graph backlink traversal, with is something that the current graph traversal inside the core can't cope with. So, let's postpone a such change if/when it is actually needed. It should also be noticed that the media_link structure uses 44 bytes on 32-bit architectures and 84 bytes on 64-bit architecture. It will thus be allocated out of the 64-bytes and 96-bytes pools respectively. That's a 12.5% memory waste on 64-bit architectures and 31.25% on 32-bit architecture. A linked list is less efficient than an array in this case, but this could later be optimized if we can get rid of the reverse links (with would reduce memory allocation by 50%).

| | | | | | | | | | | | | | The omap4iss driver initializes the entities and creates the pads links before the entities are registered with the media device. This does not work now that object IDs are used to create links so the media_device has to be set. Split out the pads links creation from the entity initialization so are made after the entities registration.
