[RFC v1 07/11] media: Add meta formats supported by NXP neoisp driver
Posted by Antoine Bouyer 2 weeks, 3 days ago 
This patch adds new v4l2 meta formats definitions and descriptions used by
neoisp driver for the parameters and statistics buffers:
 - `V4L2_META_FMT_NEO_ISP_PARAMS` used for the legacy fixed-size
parameters buffer structure.
 - `V4L2_META_FMT_NEO_ISP_EXT_PARAMS` used for the generic v4l2-isp
extensible parameters structure, supporting a non-fixed-size buffer and
changeable ISP configuration blocks.
 - `V4L2_META_FMT_NEO_ISP_STATS` used for the legacy fixed-size statistics
buffer structure.
 - `V4L2_META_FMT_NEO_ISP_EXT_STATS` used for the generic v4l2-isp
extensible statistics structure, supporting a non-fixed-size buffer
and changeable ISP statistics blocks.

Uh interesting, you have existing userspace that needs legacy formats ?

Yes we do have some available here (version with extensible formats will 
be the next one):
https://github.com/nxp-imx/libcamera

Not in mainline, thought.

I see.

However I don't think the mainline driver should support both formats.

And looking at your libcamera branch, it seem it already supports the
extensible version.

ok.

I'm fine with starting from a fresh version, extensible-format-only, in 
mainline. That would also simplify the patch series then, so as 
Documentation, and maintainance.

Oh yes you're correct. I thought it started from 6.18, sorry for 
confusion. One more reason to move to extensible-format-only in mainline 
then: it is verified since a while without any regression compared to 
legacy.
