2023-12-13media: videobuf2: core: Rename min_buffers_needed field in vb2_queueBenjamin Gaignard1-1/+1
Rename min_buffers_needed into min_queued_buffers and update the documentation about it. Signed-off-by: Benjamin Gaignard <benjamin.gaignard@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> [hverkuil: Drop the change where min_queued_buffers + 1 buffers would be] [hverkuil: allocated. Now this patch only renames this field instead of making] [hverkuil: a functional change as well.] [hverkuil: Renamed 3 remaining min_buffers_needed occurrences.]

Switch all drivers accessing sub-device state to use the stream-aware functions. We will soon remove the old ones.

2023-08-10media: v4l: async: Set v4l2_device and subdev in async notifier initSakari Ailus2-6/+4
Set the v4l2_device already in async notifier init, so struct device related to it will be available before the notifier is registered. This requires separating notifier initialisation into two functions, one that takes v4l2_device as its argument, v4l2_async_nf_init and v4l2_async_subdev_nf_init, for sub-device notifiers. Registering the notifier will use a single function, v4l2_async_nf_register. This is done in order to make struct device available earlier, during construction of the async connections, for sensible debug prints.

2023-07-28media: v4l: async: Rename v4l2_async_subdev as v4l2_async_connectionSakari Ailus4-7/+7
Rename v4l2_async_subdev as v4l2_async_connection, in order to differentiate between the sub-devices and their connections: one sub-device can have many connections but the V4L2 async framework has so far allowed just a single one. Connections in this context will later translate into either MC ancillary or data links. This patch prepares changing that relation by changing existing users of v4l2_async_subdev to switch to v4l2_async_connection. Async sub-devices themselves will not be needed anymore Additionally, __v4l2_async_nf_add_subdev() has been renamed __v4l2_async_nf_add_connection().

callback returning void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void.

In most cases, this is done with designated initializers to initialize some of the fields to specific values, but in a minority of cases the structures are zero-initialized by assigning them to '{ 0 }' or '{ }'.

It was so large that a set of identical indentation issues went unnoticed during review. Fix them.

2022-11-25media: atmel: atmel-isc: move to stagingEugen Hristev9-0/+4455
The Atmel ISC driver is not compliant with media controller specification. In order to evolve this driver, it has to move to media controller, to support enhanced features and future products which embed it. The move to media controller involves several changes which are not backwards compatible with the current usability of the driver. The best example is the way the format is propagated from the top video driver /dev/videoX down to the sensor. In a simple configuration sensor ==> isc , the isc just calls subdev s_fmt and controls the sensor directly. This is achieved by having a lot of code inside the driver that will query the subdev at probe time and make a list of formats which are usable. Basically the user has nothing to configure, as the isc will handle everything at the top level. This is an easy way to capture, but also comes with the drawback of lack of flexibility. In a more complicated pipeline sensor ==> controller 1 ==> controller 2 ==> isc this will not be achievable, as controller 1 and controller 2 might be media-controller configurable, and will not propagate the formats down to the sensor. After discussions with the media maintainers, the decision is to move Atmel ISC to staging as-is, to keep the Kconfig symbols and the users to the driver in staging. Thus, all the existing users of the non media-controller paradigm will continue to be happy and use the old config way. The new driver was added in the media subsystem with a different symbol, with the conversion to media controller done, and new users of the driver will be able to use all the new features. This patch is merely a file move to staging, not affecting any of the users. The exported symbols had to be renamed to atmel_* to avoid duplication with the new Microchip ISC driver.
