c88b6e259c libcamera: software_isp: debayer: Add missing override
Add the missing `override` specifiers in the derived classes of `Debayer`,
so that the compiler can ensure that the functions in the derived classes
really override the functions in the base class.

b4ca5e6ff8 libcamera: egl: Remove eGLImage::image_
This member stores an egl image handle, but currently there is no need for it
since the image handle is only really used in `createDMABufTexture2D()`.
(`destroyDMABufTexture()` is an unused function.)

So remove the member (and the unused function), and instead destroy the image
immediately after calling `glEGLImageTargetTexture2DOES()`. The texture will
keep a reference to the image, so this is safe to do. In fact, this solves
an issue, specifically, the egl images were never destroyed, and continuously
leaked during streaming.

5785d9649f meson: Print missing application options in summary
The recently added application options (DNG output support, KMS and SDL2
outputs for cam, and JPEG support for cam) are not printed in the
summary. This makes it more difficult to quickly assess the
configuration when those options are set to the 'auto' value. Add them
to the summary, and move all application configuration options to a
dedicated section of the summary to improve readability.

0eddf9dc01 gstreamer: Add sensor-config property
The sensor-config property may optionally be specified to give the
outputSize and bitDepth of the SensorConfiguration that is applied to
the camera configuration. For example, use

libcamerasrc sensor-config="sensor/config,width=2304,height=1296,depth=10"

to request the 10-bit 2304x1296 mode of a sensor.

All three parameters, width, height and bit depth, must be present, or
it will issue a warning and revert to automatic mode selection (as if
there were no sensor-config at all).

If a mode is requested that doesn't exist then camera configuration
will fail and the pipeline won't start.

As future-proofing, the SensorConfiguration's binning, increment and
analog-crop parameters may be specified, though libcamera currently
ignores them.

8e5eedc851 cam: Add option to report libcamera version
The cam tool is our swiss army knife for interogating libcamera.

A frequently needed piece of information is to determine what version of
libcamera is installed or being run on a system.

This information is available in the debug logs of libcamera when a
CameraManager is instantiated. However without actually starting the
CameraManager this information is not presented.

Add an option to 'cam' to allow it to report the version.  Whilst this
is the version from the 'cam' command, it directly gets the version of
the libcamera library to which cam is linked.

5f770f748c libcamera: Make converter/softISP configure()'s outputCfgs argument really const
The intent of the outputCfgs argument to the configure() function of
converter classes and the softISP is to allow the passed in stream-configs
to not be changed.

But only the vector is const, the reference inside the vector are not
const, which allows modifying the stream-configs as can be seen inside
DebayerEGL::configure() which was using a non const reference outputCfg
helper variable.

Fix this by making the references inside the vector const.

6ce7132b1b ipa: libipa: quantized: Enable constexpr operation
There is nothing inherently non-constexpr in the `Quantized` type. Whether
it can work in `constexpr` contexts depends on the traits type. There is
no reason to explicitly disallow `constexpr` operation. So mark all eligible
methods `constexpr`.

In addition, add some `static_assert()`s to the "quantized" test to check
constexpr operation.

For example, `FixedPointQTraits<...>::toFloat()` is `constexpr`, so this
enables the construction of `{U,}Q<...>` from the underlying quantized
value in `constexpr` contexts, which can be useful for example for
storing default values in e.g. `static constexpr` variables.

02277d4c1a ipa: simple: Fix again10 value with sensor helper
`CameraSensorHelper::gain(uint32_t)` maps a gain code to the actual floating
point gain value. Calling it with `1.0` as the argument will simply get
the real gain for gain code 1. This is most likely not what was intended.

For example, in the case of the `ov2740` sensor, `againMin` is 1, but the
calculated `again10` (1 / 128 ~ 0.078) ends up being < 1, meaning that the
agc algorithm will never lower the exposure.

Fix that by using the maximum of the minimum gain and 1 as `again10`.

20ea9ae1e5 py: Fix include order
Python.h hence the pybind header must be included first since pyconfig.h
unconditionally overrides certain feature test macros[0]. This was mostly
hidden by the fact that macro redefinitions with the same value do not
trigger compiler warnings. However, glibc 43 has changed certain defaults[1],
causing mismatches, leading to compiler warnings.

So change the include order so that `<pybind11/...>` headers are included
first and then the local `"py_..."` headers, and then everything else. Also
remove some redundant includes.

Adjust `.clang-format` and the documentation as well.

platforms (such as Pi 5) are easily capable of running these more
often, should there be a need to do so.

6db2a7ab43 py: Disable -Winvalid-offsetof
A "small vector" implementation has been introduced in the latest version of
pybind11 (3.0.2), which might use `offsetof()` on a non standard layout type.
This triggers the `invalid-offsetof` warning.

So disable it for the python bindings.

59be23f34e android: camera_stream: Include <poll.h> instead of <sys/poll.h>
The standard C library header for the poll() API is poll.h, not

8896ca13f1 ipa: mali-c55: agc: Quantise the ISP Digital Gain
The Mali-C55 ISP has a digital gain block which allows setting gain in Q5.8
format, a range of 0.0 to (very nearly) 32.0.

Convert usage to the new UQ<5, 8> FixedPoint Quantised type which will
support the conversion, clamping and quantisation so that the metadata
and debug prints can now report the effective gain applied instead of
the potentially inaccurate float.

6c181ac5a7 ipa: rkisp1: cproc: Provide a Hue control
The RKISP1 supports a configurable Hue as part of the colour processing
unit (cproc).

Implement the new control converting to the hardware scale accordingly
and report the applied control in the completed request metadata.

This is implemented as a phase shift of the chrominance values between
-90 and +87.188 degrees according to the datasheet however the type
itself would imply that this is a range between -90 and 89.2969.

Moreover, the hardware applies the inverse phase shift to the operation
expected and documented by libcamera, so we apply a negative scale when
converting the libcamera control to the Q<1,7> type, resulting in a
range of -89.2969 to +90.0 degrees control.
