2022-07-17media: mc-entity: Add a new helper function to get a remote pad for a padLaurent Pinchart1-0/+18
The newly added media_entity_remote_source_pad_unique() helper function handles use cases where the entity has a link enabled uniqueness constraint covering all pads. There are use cases where the constraint covers a specific pad only. Add a new media_pad_remote_pad_unique() function to handle this. It operates as media_entity_remote_source_pad_unique(), but on a given pad instead of on the entity.

2022-07-17media: mc-entity: Add a new helper function to get a remote padLaurent Pinchart1-0/+46
The media_entity_remote_pad_first() helper function returns the first remote pad it finds connected to a given pad. Beside being possibly non-deterministic (as it stops at the first enabled link), the fact that it returns the first match makes it unsuitable for drivers that need to guarantee that a single link is enabled, for instance when an entity can process data from one of multiple sources at a time. For those use cases, add a new helper function, media_entity_remote_pad_unique(), that operates on an entity and returns a remote pad, with a guarantee that only one link is enabled. To ease its use in drivers, also add an inline wrapper that locates source pads specifically. A wrapper that locates sink pads can easily be added when needed.

2022-07-17media: v4l2-async: Add notifier operation to destroy asd instancesLaurent Pinchart1-0/+2
Drivers typically extend the v4l2_async_subdev structure by embedding it in a driver-specific structure, to store per-subdev custom data. The v4l2_async_subdev instances are freed by the v4l2-async framework, which makes this mechanism cumbersome to use safely when custom data needs special treatment to be destroyed (such as freeing additional memory, or releasing references to kernel objects). To ease this, add a .destroy() operation to the v4l2_async_notifier_operations structure. The operation is called right before the v4l2_async_subdev is freed, giving drivers a chance to destroy data if needed.

This inserts 4 pixels of the RGB color 0xab55ab at the left hand side of the image. This is only done for 3 or 4 byte RGB pixel formats. The HDMI TMDS encoding of this pixel value equals the Video Guard Band value as defined by HDMI (see section 5.2.2.1 in the HDMI 1.3 Specification) that preceeds the first actual pixel of a video line. If an HDMI receiver doesn't handle this correctly, then it might keep skipping these Video Guard Band patterns and end up with a shorter video line. So this is a nice pattern to test with.

2022-05-13media: videobuf2-v4l2: Expose vb2_queue_is_busy() to driversLaurent Pinchart1-2/+21
vb2 queue ownership is managed by the ioctl handler helpers (vb2_ioctl_*). There are however use cases where drivers can benefit from checking queue ownership, for instance when open-coding an ioctl handler that needs to perform additional checks before calling the corresponding vb2 operation. Expose the vb2_queue_is_busy() function in the videobuf2-v4l2.h header, and change its first argument to a struct vb2_queue pointer as the function name implies it operates on a queue, not a video_device.

Add v4l2_subdev_get_fmt() helper function which implements v4l2_subdev_pad_ops.get_fmt using active state. Subdev drivers that support active state and do not need to do anything special in their get_fmt op can use this helper directly for v4l2_subdev_pad_ops.get_fmt.

2022-04-24media: subdev: add subdev state lockingTomi Valkeinen1-6/+127
The V4L2 subdevs have managed without centralized locking for the state (previously pad_config), as the try-state is supposedly safe (although I believe two TRY ioctls for the same fd would race), and the active-state, and its locking, is managed by the drivers internally. We now have active-state in a centralized position, and need locking. Strictly speaking the locking is only needed for new drivers that use the new state, as the current drivers continue behaving as they used to. However, active-state locking is complicated by the fact that currently the real active-state of a subdev is split into multiple parts: the new v4l2_subdev_state, subdev control state, and subdev's internal state. In the future all these three states should be combined into one state (the v4l2_subdev_state), and then a single lock for the state should be sufficient. But to solve the current split-state situation we need to share locks between the three states. This is accomplished by using the same lock management as the control handler does: we use a pointer to a mutex, allowing the driver to override the default mutex. Thus the driver can do e.g.: sd->state_lock = sd->ctrl_handler->lock; before calling v4l2_subdev_init_finalize(), resulting in sharing the same lock between the states and the controls. The locking model for active-state is such that any subdev op that gets the state as a parameter expects the state to be already locked by the caller, and expects the caller to release the lock.

Temporary wapper helper macros are added to keep the drivers using v4l2_subdev_get_try_* compiling. The next step is to change the uses in th drivers, and then drop the helpers.

2022-04-24media: subdev: add active state to struct v4l2_subdevTomi Valkeinen1-0/+58
Add a new 'active_state' field to struct v4l2_subdev to which we can store the active state of a subdev. This will place the subdev configuration into a known place, allowing us to use the state directly from the v4l2 framework, thus simplifying the drivers. Also add functions v4l2_subdev_init_finalize() and v4l2_subdev_cleanup(), which will allocate and free the active state. The functions are named in a generic way so that they can be also used for other subdev initialization work.

v4l2_subdev_alloc_state() and v4l2_subdev_free_state() are not supposed to be used by the drivers. However, we do have a few drivers that use those at the moment, so we need to expose these functions for the time being. Prefix the functions with __ to mark the functions as internal. At the same time, rename them to v4l2_subdev_state_alloc and v4l2_subdev_state_free to match the style used for other functions like video_device_alloc() and media_request_alloc().
