To do actual lens dewarping, the dewarper will be configured based on
the tuning file.
As a first step implement the basic loading of the
tuning file and enable/disable the dewarper for the given camera based
on the existence of the "Dewarp" entry under a new top level element
'modules' in the tuning file.
Note: This is an backwards incompatible change in that the dewarper is
currently included in the chain unconditionally. Some users may want to
not use the dewarper, so it is sensible to make that configurable.

In raw mode the number of configurations is actively limited to 1. It is
therefore safe to move isRaw up one level to simplify the code and
prepare for later use.
During that rework it was noticed that the old code actually has a bug
in that it reduces the number of configurations to 1 in case a raw
config is found, but it doesn't reduce the config vector to that raw
config, but the first config.
Change that behavior to check the first config and either remove all
remaining configs if the first is raw or drop all raw configs if the
first is non-raw.

The dewarper integration into the rkisp1 pipeline is quite complicated.
Simplify that by switching to the now available ConverterDW100Module. As
there is no other known converter in combination with the rkisp1 ISP this
is a safe step to do.
This change also paves the way to implement dw100 specific features later.
The input crop implemented in the dw100 kernel driver is quite limited
in that it doesn't allow arbitrary crop rectangles but only scale
factors quantized to the underlying fixed point representation and only
aspect ratio preserving crops.
The vertex map based implementation allows for pixel perfect crops. The
only downside is that ScalerCrop can no longer be set dynamically on
older kernels. A corresponding warning is already implemented in the
converter module.

When the dewarper is used, an addition buffer loop with
kRkISP1MinBufferCount buffers is created between ISP and dewarper. When
the dewarper is configured, it stores the bufferCount value of the
requested stream configurations. This number of buffers is then imported
when the dewarper is started.
On the input stream of the dewarper the bufferCount is currently left
unchanged, meaning it carries the bufferCount as supplied by the user
instead of the bufferCount of the additional loop. Fix that by setting

For choosing the colorspace for the generated NV12 frames, following
points have been taken into account:
- The transfer function should be Rec.709 for NV12
- The YCbCr encoding has been chosen Rec.709 as it is the most common
than Rec.601/Rec.2020
- Range should be 'Limited' as with the NV12 pixel format.

The Simple Pipeline is designed to support a wide variety of pipeline

of the connected sensors to map these to libcamera formats where
available.
In fixed pipelines, where the pixel format is not mapped correctly it is
a desired behaviour to express this warning so that the pixelformat can
be added, while in the simple-pipeline case we do not expect warnings
for every discovered pixel format which is not supported by libcamera.
This currently manifests itself as very highly verbose warnings about
unsupported pixel formats are not desired when there are working formats
that have already been enumerated.
Fortunately in commit 434edb7b44 ("libcamera: formats: Fix warning for

occasions where we wish to ignore unsupported formats.
Use this feature to disable the warning in the core V4L2PixelFormat and
instead report only a debug level print from the simple pipeline

Software CPU ISP computes a gamma lookup table. The table incorporates
black level and contrast. All entries in the table below the black
level are set to 0. This is not necessarily correct all the time.
Let's consider this case: The CCM is
[1 0 0]
[0 1 0]
[0 0 0]
and contrast is set to zero. The gamma table has all the entries above
the black level set to 186 (due to zero contrast) and all the entries
below the black level set to 0. CCM is applied before gamma, a
non-black level pixel has the blue component set to 0 with the CCM
above. Now, when the gamma lookup is applied, the red and green
components are set to 186, while the blue component is set to 0. The
resulting pixel is then yellow rather than grey (as it should be with
zero contrast).
There are two ways to fix this: Either clamping pixel colour channels to
the black level in debayering or setting the below black level entries
in the gamma lookup table to the lowest value of the gamma table rather
than 0. Both should have the same effect. Let's opt for the latter for
its simplicity.

The libyuv wrap uses a libyuv commit between versions 1770 and 1772,
more than 5 years old. This specifies CMake 2.8 as the minimum required
version.
The most recent CMake has dropped compatibility with versions older than
3.5 in CMake 4.0. CMake 3.5 was released in 2016, and all distributions
we care about ship more recent versions. With CMake 4.0 or newer,
shipped for instance by Gentoo, compilation of the libyuv wrap fails.
Update the wrap to version 1922, which is the latest numbered version
(libyuv doesn't tag release by increases a version number in the
README.chromium file). This requires CMake 3.16, released 6 years ago,
and available in at least the last two LTS of major distributions.
This update introduces two issues. First, due to a bug in Meson (see
https://github.com/mesonbuild/meson/issues/10764), PIC handling is
broken when a CMake project wraps a static library into another static
library that has no additional source file. Work around it by wrapping
the libyuv static library again, manually setting 'pic' to true.
The second issue is that libyuv fails to compile for armhf platforms
that don't support NEON instructions. This is the case on Debian 12 and
13 that ship armhf toolchains with NEON disabled by default. The issue
causes CI failures. As the libyuv wrap is a convenience measure, disable
NEON optimization on armfd platforms the same way Debian does in its
armhf packages. If NEON support is important, the build environment
should provide a suitable libyuv.
