When looking into supporting the rkisp1 of the px30 I noticed that some fields got bigger in the uapi, caused by bigger number of samples for example for histograms or gamma values. The rkisp1 was destaged with 5.11-rc1 so we have still time during the 5.11 cycle to fix that without big hassles. This was discussed previously in a mail [0] and a rfc series [1] and this two-part series now splits out the important parts that really should become part of a 5.11-rc and thus the final 5.11. changes since v3: - add patch fixing the original histogram size comment - make comments in uapi more verbose (Hans) - fix wording in admin guide (Hans) - document version <-> soc in uapi as well (easier for people) (Dafna) changes since v2: - actually zero the correct sizes for u16 values (hist-bins) (kernel-test-robot) changes since v1: - drop duplicate isp_ver storage, hw_revision is enough (Dafna) - document multiple maximum sizes in uapi (Hans) - document usage of hw_revision field (Hans) - zero fields transmitted to userspace before adding data (Hans) - use _V10 field sizes when filling fields, as there is only v10 for now changes since rfc: - move rkisp1_version enum into uapo - show version in media-api hw_revision - introduce constants for versions and make max use the biggest Heiko Stuebner (3): media: rockchip: rkisp1: fix comment about number of histogram sub-windows media: rockchip: rkisp1: carry ip version information media: rockchip: rkisp1: extend uapi array sizes Documentation/admin-guide/media/rkisp1.rst | 16 ++++ .../platform/rockchip/rkisp1/rkisp1-dev.c | 21 +++--- .../platform/rockchip/rkisp1/rkisp1-params.c | 2 +- .../platform/rockchip/rkisp1/rkisp1-stats.c | 12 ++- include/uapi/linux/rkisp1-config.h | 74 +++++++++++++++++-- 5 files changed, 106 insertions(+), 19 deletions(-)
