[PATCH v13 00/34] v4l: routing and streams support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

This is v13 of the streams series. The v12 can be found from:

https://lore.kernel.org/all/20220727103639.581567-1-tomi.valkeinen@xxxxxxxxxxxxxxxx/

My work branch with additional drivers can be found from:

git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux.git streams/work-v13

And there's also the v4l-utils series v2 to add support to v4l2-ctl and
media-ctl:

https://lore.kernel.org/all/20220714132116.132498-1-tomi.valkeinen@xxxxxxxxxxxxxxxx/

Changes in v13 to v12

* media_pipeline_alloc_start: handle no mem error
* Automatically free the allocated pipeline in media_pipeline_stop()
* sanity checks for media_entity_pipeline
* improve v4l2_link_validate_get_streams (drop 'is_source')
* indent Add iterator helper for entity pads
* v4l2_subdev_set_routing: leave the current routing untouched in case of error
* v4l2_subdev_init_stream_configs: leave the current routing untouched in case of error
* Drop V4L2_SUBDEV_ROUTE_FL_IMMUTABLE
* In subdev ioctls, check that stream == 0 if subdev doesn't support streams
* Squash for_each_active_route() uses
* Add media_pad_pipeline()
* Add video device pipeline helpers and use them in the drivers
* Rename has_route to has_pad_interdep
