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/raspberrypi/controller/histogram.h | 53 ------------------------------ 1 file changed, 53 deletions(-) delete mode 100644 src/ipa/raspberrypi/controller/histogram.h (limited to 'src/ipa/raspberrypi/controller/histogram.h') diff --git a/src/ipa/raspberrypi/controller/histogram.h b/src/ipa/raspberrypi/controller/histogram.h deleted file mode 100644 index 6b3e3a9e..00000000 --- a/src/ipa/raspberrypi/controller/histogram.h +++ /dev/null @@ -1,53 +0,0 @@ -/* SPDX-License-Identifier: BSD-2-Clause */ -/* - * Copyright (C) 2019, Raspberry Pi Ltd - * - * histogram.h - histogram calculation interface - */ -#pragma once - -#include -#include -#include - -/* - * A simple histogram class, for use in particular to find "quantiles" and - * averages between "quantiles". - */ - -namespace RPiController { - -class Histogram -{ -public: - Histogram() - { - cumulative_.push_back(0); - } - - template Histogram(T *histogram, int num) - { - assert(num); - cumulative_.reserve(num + 1); - cumulative_.push_back(0); - for (int i = 0; i < num; i++) - cumulative_.push_back(cumulative_.back() + - histogram[i]); - } - uint32_t bins() const { return cumulative_.size() - 1; } - uint64_t total() const { return cumulative_[cumulative_.size() - 1]; } - /* Cumulative frequency up to a (fractional) point in a bin. */ - uint64_t cumulativeFreq(double bin) const; - /* - * Return the (fractional) bin of the point q (0 <= q <= 1) through the - * histogram.
