This metadata is fixed and not configurable from userspace. Since the metadata has no dimensions, it makes sense to set the width and height of these pads to 0. The problem is that it makes the v4l-compliance tests fail. Currently, in order to silent the tests, the width and height are set to RKISP1_DEFAULT_* This patchset sets the dimensions to 0 and solves the compliance error by introducing a new media bus code MEDIA_BUS_FMT_METADATA_FIXED The new code should be used when the same driver handles both sides of the link and the bus format is a fixed metadata format that is not configurable from userspace. Then the v4l2-compliance tests can skip the dimensions test for this media bus code. See irc discussion for that issue: https://linuxtv.org/irc/irclogger_log/v4l?date=2020-05-13,Wed https://linuxtv.org/irc/irclogger_log/v4l?date=2020-05-14,Thu Dafna Hirschfeld (2): meida: uapi: add MEDIA_BUS_FMT_METADATA_FIXED media bus format. media: staging: rkisp1: isp: set metadata pads to MEDIA_BUS_FMT_METADATA_FIXED drivers/staging/media/rkisp1/TODO | 1 - drivers/staging/media/rkisp1/rkisp1-isp.c | 8 ++++---- include/uapi/linux/media-bus-format.h | 8 ++++++++ 3 files changed, 12 insertions(+), 5 deletions(-)
