+Date: Mon, 11 Mar 2024 15:15:10 +0100
+Subject: [PATCH 06/21] libcamera: software_isp: Add SwStatsCpu class
+
+Add a CPU based SwStats implementation for SoftwareISP / SoftIPA use.
+
+This implementation offers a configure function + functions to gather
+statistics on a line by line basis. This allows CPU based software
+debayering to call into interlace debayering and statistics gathering
+on a line by line bases while the input data is still hot in the cache.
+
+This implementation also allows specifying a window over which to gather
+statistics instead of processing the whole frame.
+
+Doxygen documentation by Dennis Bonke.

-From ca3bb6ddf5307537aa05e43d3ec1ff7ffdc0efed Mon Sep 17 00:00:00 2001
-From: Hans de Goede <hdegoede@redhat.com>
-Date: Thu, 7 Dec 2023 13:30:27 +0100
-Subject: [PATCH 07/25] libcamera: software_isp: Add SwStats base class
-
-Add a virtual base class for CPU based software statistics gathering
-implementations.
-
-The idea is for the implementations to offer a configure function +
-functions to gather statistics on a line by line basis. This allows
-CPU based software debayering to call into interlace debayering and
-statistics gathering on a line by line bases while the input data
-is still hot in the cache.
-
-This base class also allows the user of an implementation to specify
-a window over which to gather statistics instead of processing the
-whole frame; and it allows the implementation to choose to only
-process 1/2, 1/4th, etc. of the lines instead of processing all
-lines (in the window) by setting y_skip_mask_ from configure().
-Skipping columns is left up the line-processing functions provided
-by the implementation.
-
-Doxygen documentation by Dennis Bonke.

++	 *
++	 * Input data is an array of (patternSize_.height + 1) src
++	 * pointers each pointing to a line in the Bayer source. The middle
++	 * element of the array will point to the actual line being processed.
++	 * Earlier element(s) will point to the previous line(s) and later
++	 * element(s) to the next line(s).
++	 *
++	 * These functions take an array of src pointers, rather than
++	 * a single src pointer + a stride for the source, so that when the src
++	 * is slow uncached memory it can be copied to faster memory before
++	 * debayering. Debayering a standard 2x2 Bayer pattern requires access
++	 * to the previous and next src lines for interpolating the missing
++	 * colors. To allow copying the src lines only once 3 temporary buffers
++	 * each holding a single line are used, re-using the oldest buffer for
++	 * the next line and the pointers are swizzled so that:
++	 * src[0] = previous-line, src[1] = currrent-line, src[2] = next-line.
++	 * This way the 3 pointers passed to the debayer functions form
++	 * a sliding window over the src avoiding the need to copy each
++	 * line more than once.
++	 *
++	 * Similarly for bayer patterns which repeat every 4 lines, 5 src
++	 * pointers are passed holding: src[0] = 2-lines-up, src[1] = 1-line-up
++	 * src[2] = current-line, src[3] = 1-line-down, src[4] = 2-lines-down.

+From 5261c801d8425fa82bcbd3da0199d06153eb5bd7 Mon Sep 17 00:00:00 2001
+From: Andrey Konovalov <andrey.konovalov@linaro.org>
+Date: Mon, 11 Mar 2024 15:15:13 +0100
+Subject: [PATCH 09/21] libcamera: ipa: add Soft IPA
+
+Define the Soft IPA main and event interfaces, add the Soft IPA
+implementation.
+
+The current src/ipa/meson.build assumes the IPA name to match the
+pipeline name. For this reason "-Dipas=simple" is used for the
+Soft IPA module.
+
+Auto exposure/gain and AWB implementation by Dennis, Toon and Martti.
+
+Auto exposure/gain targets a Mean Sample Value of 2.5 following
+the MSV calculation algorithm from:

+Subject: [PATCH 12/21] libcamera: pipeline: simple: enable use of Soft ISP and
  Soft IPA
 
 To enable the Simple Soft ISP and Soft IPA for simple pipeline handler
 configure the build with:
-  -Dpipelines=simple/simple -Dipas=simple/simple
+  -Dpipelines=simple -Dipas=simple
+
+Also using the Soft ISP for the particular hardware platform must
+be enabled in the supportedDevices[] table.
 
 If the pipeline uses Converter, Soft ISP and Soft IPA aren't
 available.
 
-Configuring the build with just:
-  -Dpipelines=simple
-makes it to work like before - Soft ISP and Soft IPA aren't used.

+Subject: [PATCH 18/21] libcamera: software_isp: Apply black level compensation
+
+Black may not be represented as 0 pixel value for given hardware, it may be
+higher.  If this is not compensated then various problems may occur such as low
+contrast or suboptimal exposure.
+
+The black pixel value can be either retrieved from a tuning file for the given
+hardware, or automatically on fly.  The former is the right and correct method,
+while the latter can be used when a tuning file is not available for the given
+hardware.  Since there is currently no support for tuning files in software ISP,
+the automatic, hardware independent way, is always used.  Support for tuning
+files should be added in future but it will require more work than this patch.
+
+The patch looks at the image histogram and assumes that black starts when pixel
+values start occurring on the left.  A certain amount of the darkest pixels is
+ignored; it doesn't matter whether they represent various kinds of noise or are
+real, they are better to omit in any case to make the image looking better.  It
+also doesn't matter whether the darkest pixels occur around the supposed black
+level or are spread between 0 and the black level, the difference is not
+important.
+
+An arbitrary threshold of 2% darkest pixels is applied; there is no magic about
+that value.
+
+The patch assumes that the black values for different colors are the same and
+doesn't attempt any other non-primitive enhancements.  It cannot completely
+replace tuning files and simplicity, while providing visible benefit, is its
+goal.  Anything more sophisticated is left for future patches.
+
+A possible cheap enhancement, if needed, could be setting exposure + gain to
+minimum values temporarily, before setting the black level.  In theory, the
+black level should be fixed but it may not be reached in all images.  For this
+reason, the patch updates black level only if the observed value is lower than
+the current one; it should be never increased.
+
+The purpose of the patch is to compensate for hardware properties.  General
+image contrast enhancements are out of scope of this patch.
+
+Stats are still gathered as an uncorrected histogram, to avoid any confusion and
+to represent the raw image data.  Exposure must be determined after the black
+level correction -- it has no influence on the sub-black area and must be
+correct after applying the black level correction.  The granularity of the
+histogram is increased from 16 to 64 to provide a better precision (there is no
+theory behind either of those numbers).

+Subject: [PATCH 19/21] libcamera: Soft IPA: use CameraSensorHelper for
+ analogue gain
+
+Use CameraSensorHelper to convert the analogue gain code read from the
+camera sensor into real analogue gain value. In the future this makes
+it possible to use faster AE/AGC algorithm. For now the same AE/AGC
+algorithm is used, but even then the CameraSensorHelper lets us use the
+full range of analogue gain values.
+
+If there is no CameraSensorHelper for the camera sensor in use, a
+warning log message is printed, and the AE/AGC works exactly as before
+this change.
