Implement color space support in the rkisp1 pipeline handler, in the
configuration generation, configuration validation and camera
configuration. As all the processing related to the color space is
performed in the part of the pipeline shared by all streams, a single
color space must cover all stream configurations. This is enforced
manually when generating the configuration, and with the
validateColorSpaces() helper when validating it.
Only the Y'CbCr encoding and quantization range are currently taken into
account, and they are programmed through the V4L2 color space API. The
primary colors chromaticities and the transfer function need to be
configured in the ISP parameters buffer, and thus conveyed to the IPA,
but the rkisp1 driver does not currently support tone mapping, so this
will be done later.

This script generates fixed-point integer coefficients for the YCbCr
encoding 3x3 matrix. The encoding, quantization and fixed-point
precision can be selected through command line arguments.
The main purpose of the script is to generate coefficient tables to
extend the rkisp1 driver with support for additional YCbCr encodings,
but it may be useful for other purposes as well given that the rounding
isn't trivial.
The Rec. 601 full and limited range coefficients have been verified to
match the values currently used by the rkisp1 driver.

The JPEG color space is badly name, as the JPEG specification (ITU-T
T.81) doesn't define any particular color space:
The interchange format does not specify a complete coded image
representation. Application-dependent information, e.g. colour
space, is outside the scope of this Specification.
The JFIF specification (ITU-T T.871) is clearer as it requires ITU-R
BT.601 YCbCr encoding and a full quantization range:
The interpretations of Y, CB, and CR are derived from the E'Y, E'Cb,
and E'Cr signals defined in the 625-line specification of Rec. ITU-R
BT.601, but these signals are normalized so as to permit the usage of
the full range of 256 levels of the 8-bit binary encoding of the Y
component.
It however doesn't specify color primaries or a transfer function
explicitly. It only mentions the latter when describing the conversion
from YCbCr to RGB:
The inverse relationship for computing full scale 8-bit per colour
channel gamma pre-corrected RGB values (following Rec. ITU-R BT.601
gamma pre-correction and colour primary specifications) from YCbCr
colours (with 256 levels per component) can be computed as follows:
[...]
Given that ITU-R BT.601-5 (1995) didn't specify color primaries or a
transfer function, and that the later ITU-R BT.601-7 (2011) version
specifies color primaries for the 625-line variant that do not match
sRGB, the JPEG color space in libcamera is badly named. This is
confirmed by ITU-T T.871:
As this Recommendation | International Standard is based on the prior
informally-circulated JFIF version 1.02 specification that was
produced in 1992, which referenced Rec. ITU-R BT.601 (formerly CCIR
601), it references that specification for definition of the E'Y,
E'Cb, and E'Cr signals that correspond to the YCBCR values specified
herein. However, since the development of the prior JFIF version 1.02
specification, additional industry specifications have been developed,
Rec. ITU-R BT.601 has been updated, and common industry practice has
emerged which often follows the sYCC specification in IEC
61966-2-1/Amd.1. The difference between the use of the colour
interpretation specification in this Recommendation | International
Standard and that of the sYCC specification may be considered
negligible in practice.
Rename the color space to sYCC, as its definition matches the sYCC
standard, and indicate that it is typically used to encode JPEG images.

libcamera implements a pipeline handler locking mechanism based on
advisory locks on media devices, to prevent concurrent access to cameras
from the same pipeline handler from different processes (this only works
between multiple libcamera instances, as other processes won't use
advisory locks on media devices).
A side effect of the implementation prevents multiple cameras created by
the same pipeline handler from being used concurrently. Fix this by
turning the PipelineHandler lock() and unlock() functions into acquire()
and release(), with a use count to replace the boolean lock flag. The
Camera class is updated accordingly.
As a consequence of this change, the IPU3 pipeline handler will fail to
operate properly when the cameras it exposes are operated concurrently.
The android.hardware.camera2.cts.MultiViewTest#testDualCameraPreview
test fails as a result. This should be fixed in the IPU3 pipeline
handler to implement mutual exclusion between cameras.

As part of the series that contains such commit, the PixelFormatInfo for the
pixel format applied to a video device is now retrieved at
V4L2VideoDevice::open() time. Some video devices register formats not
available to applications, for example metadata formats or, in the case
of ISP devices, formats to describe the ISP statistics and parameters.
This causes the
format.toPixelFormat()
call to output a WARN message, which spams the log and unnecessarily alerts
the users.
Augment V4L2PixelFormat::toPixelFormat() with an optional argument to
suppress warnings in the case a V4L2 pixel format is not known, to

Commit b382f67c833d ("libcamera: Make IPA module signing mandatory for
the meantime") made openssl and gnutls dependencies mandatory to work
around the lack of proper IPA module isolation support, which broke
operation without module signatures. This has now been fixed, so IPA
module isolation isn't strictly required anymore.
There are few use cases for disabling module signing completely, given
that the openssl or gnutls dependencies are available on the vast
majority of systems and the overheard introduced by isolating all IPA
modules when signatures are not available is better avoided.
Nonetheless, libcamera should operate properly with forced IPA module
isolation, so we can support those use cases.
Adopt a middle-ground approach to avoid unintentional isolation by
documenting the dependencies as recommended, and warn at meson setup
time if they are not found.
