Subject: [PATCH v3 00/14] Generic line based metadata, without sensor API changes
Date: Fri, 26 Apr 2024 11:50:24 +0300 [thread overview]
Message-ID: <20240426085038.943733-1-sakari.ailus@linux.intel.com> (raw)
Hello everyone,
I've split these patches off the metadata set [1], it'll still take more
time to merge the internal pad support as it is evident we need to
properly define the recommended sensor APIs to merge the drivers that are
using them.
In the meantime, these patches are seen as what can be merged for 6.10.
The patches include changes to the routing API before the internal pads.
[1] <URL:https://lore.kernel.org/linux-media/20240420100518.GA5618@pendragon.ideasonboard.com/T/#t>
changes since v2:
- Fix glossary term referencing (thanks to Hans!).
changes since v1:
- Improve len_routes field documentation in struct v4l2_subdev_routing.
changes since v9 metadata set:
- Fix metadata format documentation.
- Improve language of struct v4l2_subdev_format field documentation when
it comes to metadata.
- Improved documentation for routing API.
- Set (and unset) the V4L2_FMT_FLAG_META_LINE_BASED flag in the framework
based on the format, don't rely on the driver to do it. Added a comment
to the format list to remind developers to update v4l_fill_fmtdesc when
adding new metadata formats.
- Drop the patch that moved G_ROUTING below S_ROUTING handling in
v4l2-subdev.c. It's no longer needed.
