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/device_status.h | 43 ++++++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 src/ipa/rpi/controller/device_status.h (limited to 'src/ipa/rpi/controller/device_status.h') diff --git a/src/ipa/rpi/controller/device_status.h b/src/ipa/rpi/controller/device_status.h new file mode 100644 index 00000000..c45db749 --- /dev/null +++ b/src/ipa/rpi/controller/device_status.h @@ -0,0 +1,43 @@ +/* SPDX-License-Identifier: BSD-2-Clause */ +/* + * Copyright (C) 2019-2021, Raspberry Pi Ltd + * + * device_status.h - device (image sensor) status + */ +#pragma once + +#include +#include + +#include + +/* + * Definition of "device metadata" which stores things like shutter time and + * analogue gain that downstream control algorithms will want to know. + */ + +struct DeviceStatus { + DeviceStatus() + : shutterSpeed(std::chrono::seconds(0)), frameLength(0), + lineLength(std::chrono::seconds(0)), analogueGain(0.0) + { + } + + friend std::ostream &operator<<(std::ostream &out, const DeviceStatus &d); + + /* time shutter is open */ + libcamera::utils::Duration shutterSpeed; + /* frame length given in number of lines */ + uint32_t frameLength; + /* line length for the current frame */ + libcamera::utils::Duration lineLength; + double analogueGain; + /* 1.0/distance-in-metres */ + std::optional lensPosition; + /* 1/f so that brightness quadruples when this doubles */ + std::optional aperture; + /* proportional to brightness with 0 = no flash, 1 = maximum flash */ + std::optional flashIntensity; + /* Sensor reported temperature value (in degrees) */ + std::optional sensorTemperature; +}; -- cgit v1.2.1
