From 726e9274ea95fa46352556d340c5793a8da51fcd Mon Sep 17 00:00:00 2001 From: Naushir Patuck Date: Wed, 3 May 2023 13:20:27 +0100 Subject: pipeline: ipa: raspberrypi: Refactor and move the Raspberry Pi code Split the Raspberry Pi pipeline handler and IPA source code into common and VC4/BCM2835 specific file structures. For the pipeline handler, the common code files now live in src/libcamera/pipeline/rpi/common/ and the VC4-specific files in src/libcamera/pipeline/rpi/vc4/. For the IPA, the common code files now live in src/ipa/rpi/{cam_helper,controller}/ and the vc4 specific files in src/ipa/rpi/vc4/. With this change, the camera tuning files are now installed under share/libcamera/ipa/rpi/vc4/. To build the pipeline and IPA, the meson configuration options have now changed from "raspberrypi" to "rpi/vc4": meson setup build -Dipas=rpi/vc4 -Dpipelines=rpi/vc4 Signed-off-by: Naushir Patuck Reviewed-by: Jacopo Mondi Reviewed-by: Laurent Pinchart Signed-off-by: Laurent Pinchart --- src/ipa/rpi/controller/agc_status.h | 37 +++++++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 src/ipa/rpi/controller/agc_status.h (limited to 'src/ipa/rpi/controller/agc_status.h') diff --git a/src/ipa/rpi/controller/agc_status.h b/src/ipa/rpi/controller/agc_status.h new file mode 100644 index 00000000..6abf09d9 --- /dev/null +++ b/src/ipa/rpi/controller/agc_status.h @@ -0,0 +1,37 @@ +/* SPDX-License-Identifier: BSD-2-Clause */ +/* + * Copyright (C) 2019, Raspberry Pi Ltd + * + * agc_status.h - AGC/AEC control algorithm status + */ +#pragma once + +#include + +/* + * The AGC algorithm should post the following structure into the image's + * "agc.status" metadata. + */ + +/* + * Note: total_exposure_value will be reported as zero until the algorithm has + * seen statistics and calculated meaningful values.
