git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull second batch of media updates from Mauro Carvalho Chehab: "This is the second part of the media patches. It contains the media controller next generation patches, with is the result of one year of discussions and development. It also contains patches to enable media controller support at the DVB subsystem. The goal is to improve the media controller to allow proper support for other types of Video4Linux devices (radio and TV ones) and to extend the media controller functionality to allow it to be used by other subsystems like DVB, ALSA and IIO. In order to use the new functionality, a new ioctl is needed (MEDIA_IOC_G_TOPOLOGY). As we're still discussing how to pack the struct fields of this ioctl in order to avoid compat32 issues, I decided to add a patch at the end of this series commenting out the new ioctl, in order to postpone the addition of the new ioctl to the next Kernel version (4.6). With that, no userspace visible changes should happen at the media controller API, as the existing ioctls are untouched. Yet, it helps DVB, ALSA and IIO developers to develop and test the patches adding media controller support there, as the core will contain all required internal changes to allow adding support for devices that belong to those subsystems" * tag 'media/v4.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (177 commits) [media] Postpone the addition of MEDIA_IOC_G_TOPOLOGY [media] mxl111sf: Add a tuner entity [media] dvbdev: create links on devices with multiple frontends [media] media-entitiy: add a function to create multiple links [media] dvb-usb-v2: postpone removal of media_device [media] dvbdev: Add RF connector if needed [media] dvbdev: remove two dead functions if !CONFIG_MEDIA_CONTROLLER_DVB [media] call media_device_init() before registering the V4L2 device [media] uapi/media.h: Use u32 for the number of graph objects [media] media-entity: don't sleep at media_device_register_entity() [media] media-entity: increase max number of PADs [media] media-entity.h: document the remaining functions [media] media-device.h: use just one u32 counter for object ID [media] media-entity.h fix documentation for several parameters [media] DocBook: document media_entity_graph_walk_cleanup() [media] move documentation to the header files [media] media: Move MEDIA_ENTITY_MAX_PADS from media-entity.h to media-entity.c [media] media: Remove pre-allocated entity enumeration bitmap [media] staging: v4l: davinci_vpbe: Use the new media graph walk interface [media] staging: v4l: omap4iss: Use the new media graph walk interface ...

2016-01-11[media] media-device: split media initialization and registrationJavier Martinez Canillas
The media device node is registered and so made visible to user-space before entities are registered and links created which means that the media graph obtained by user-space could be only partially enumerated if that happens too early before all the graph has been created. To avoid this race condition, split the media init and registration in separate functions and only register the media device node when all the pending subdevices have been registered, either explicitly by the driver or asynchronously using v4l2_async_register_subdev(). The media_device_register() had a check for drivers not filling dev and model fields but all drivers in mainline set them and not doing it will be a driver bug so change the function return to void and add a BUG_ON() for dev being NULL instead. Also, add a media_device_cleanup() function that will destroy the graph_mutex that is initialized in media_device_init().

2016-01-11[media] media framework: rename pads init function to media_entity_pads_init()Mauro Carvalho Chehab
With the MC next gen rework, what's left for media_entity_init() is to just initialize the PADs. However, certain devices, like a FLASH led/light doesn't have any input or output PAD. So, there's no reason why calling media_entity_init() would be mandatory. Also, despite its name, what this function actually does is to initialize the PADs data. So, rename it to media_entity_pads_init() in order to reflect that. The media entity actual init happens during entity register, at media_device_register_entity(). We should move init of num_links and num_backlinks to it. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2016-01-11[media] media: convert links from array to listMauro Carvalho Chehab
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%).

2016-01-11[media] uvcvideo: create pad links after subdev registrationJavier Martinez Canillas

2016-01-11[media] media: rename the function that create pad linksMauro Carvalho Chehab

2016-01-11[media] media: get rid of unused "extra_links" param on media_entity_init()Mauro Carvalho Chehab
Currently, media_entity_init() creates an array with the links, allocated at init time. It provides a parameter (extra_links) that would allocate more links than the current needs, but this is not used by any driver. As we want to be able to do dynamic link allocation/removal, we'll need to change the implementation of the links. So, before doing that, let's first remove that extra unused parameter, in order to cleanup the interface first.

2015-12-18[media] vb2: drop v4l2_format argument from queue_setupHans Verkuil
The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2015-11-19[media] uvcvideo: Enable UVC 1.5 device detectionLaurent Pinchart
UVC 1.5 devices report a bInterfaceProtocol value set to 1 in their interface descriptors. The uvcvideo driver only matches on bInterfaceProtocol 0, preventing those devices from being detected. More changes to the driver are needed for full UVC 1.5 compatibility. However, at least the UVC 1.5 Microsoft Surface Pro 3 cameras have been reported to work out of the box with the driver with an updated match table. Enable UVC 1.5 support in the match table to support the devices that can work with the current driver implementation. Devices that can't will fail, but that's hardly a regression as they're currently not detected at all anyway.

2015-11-19[media] em28xx: add Terratec Cinergy T XS (MT2060)Alberto Mardegan
The Terratec Cinergy T XS is a DVB-T receiver with no analog TV tuner. This patch adds support for the cards carrying the mt2060 tuner; it's unclear whether there are cards sold under the same name which use a different tuner. As long as there are no reports of such cards, and indeed as long as there are no working drivers for them, we assume that the USB device [0ccd:0043] is carrying the mt2060 tuner.

In case the request to locate the firmware file part 2 fails, the error path releases the already freed firmware memory location again. Thus reset the firmware pointer to NULL after releasing firmware file part 1. Signed-off-by: Christian Engelmayer <cengelma@gmx.at> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
