Subject: Re: [PATCH v8 05/38] media: uapi: Add generic 8-bit metadata format definitions
Date: Wed, 20 Mar 2024 01:37:01 +0200 [thread overview]
Message-ID: <20240319233701.GJ8501@pendragon.ideasonboard.com> (raw)

Hi Sakari,
Thank you for the patch.
Mentioning V4L2 on the subject line would help differentiating this from
the media bus codes.

I think the intention was to keep those alphabetically sorted, even if
vivid is out of order already.

Doesn't really sound packed, when you have one byte of padding after
four bytes of data :-) I understand where this "packing" is from, but
the documentation seems confusing for people not familiar with the
topic. How about simplifying it as follows ?
V4L2_META_FMT_GENERIC_CSI2_10 contains 8-bit generic metadata, stored with one
padding byte after every four bytes of metadata. This is usually produced by
CSI-2 receivers with a source that transmits MEDIA_BUS_FMT_META_10, when the
CSI-2 receiver packs the received data as defined in the MIPI CSI-2
specification.

How is it little endian when it's byte-oriented ?

'M' and 'x'.
These comments apply to the formats below too.

You could write "8-bit Generic Meta, 10b CSI-2" and it would still fit.
