A bug in libcxx [0] used by clang version 11.0.2 is prevalent when
building libcamera for Android SDK30. This has been fixed and
integrated upstream with [1].
As a workaround, directly cast libcamera::utils::Duration objects to
std::chrono::duration when dividing.
Alternatives evaluated:
Considered: Enable public inheritance of std::chrono::duration and
override operator/ in the class.
Outcome: Does not fix the original compiler error.
Considered: Enable public inheritance of std::chrono::duration and
override operator/ in the libcamera namespace.
Outcome: new compiler error:
ld.lld: error: duplicate symbol: libcamera::operator/
(libcamera::utils::Duration const&, libcamera::utils::Duration const&)
Considered: Use private inheritance of std::chrono::duration and
re-implement a pass-through version of each std::chrono::duration
operator within libcamera::utils::Duration and use template
metaprogramming to fix the division operator.
Outcome: Testing shows that this would introduce substantial
limitations, i.e. requring the Duration object to be on the LHS of any
arithmetic operation with other numeric types. This also substantially
increases implementation complexity.
Considered: Extract double values from libcamera::utils::Duration
objects and use those to divide.
Outcome: This creates substantial readability and unit-safety issues.

Currently, libcamera does not have information for the ov8858 sensor
used in the PinePhone Pro, a phone designed to run Linux.
This commit adds metadata, especially that sensor gain is reported and
set in 1/16 discrete increments.
For more information, see "5.8 manual exposure compensation/ manual
gain compensation" in [0] and the driver in [1].

Augment the CameraSensor::setFormat() function to configure horizontal
and vertical flips before appllying the image format on the sensor.
Applying flips before format is crucial as they might change the Bayer
pattern ordering.
To allow users of the CameraSensor class to easily pass the requested
Transform add to the V4L2SubdeviceFormat class a 'transform' member, by
default initialized to Transform::Identity.
Moving the handling of H/V flips to the CameraSensor class allows to
remove quite some boilerplate code from the IPU3 and RaspberryPi
pipeline handlers.

The two pipeline handlers that currently support Transform do so by
operating H/V flips on the image sensor, instead of rotating on the ISP.
As the image sensor performs the actual rotation, centralize the code
that validates a requested Transform against the camera sensor rotation
and capabilities in the CameraSensor class.
The implementation in the IPU3 pipeline handler was copied from the
RaspberryPi implementation, and is now centralized in CameraSensor to
make it easier for other platforms that do not rotate on the ISP to
implement support for Transform using the CameraSensor class.

The current documentation of the BayerFormat::transform() function
reports examples on the Bayer components ordering transformation for
horizontal flip (mirroring) but not for vertical flip or for the
combination of the two.
It might be useful to complete the documentation to eases understanding
of the transform() function on a sensor's Bayer pattern.

Previously the code used to clear the camnera's h and v flip bits when
enumerating the supported formats so as to obtain any Bayer formats in
the sensor's native (untransformed) orientation. However this fails
when the camera is already in use elsewhere.
Instead, we query the current state of the flip bits and transform the
formats - which we obtain in their flipped orientation - back into
their native orientation to be stored.

Implement support for raw Bayer capture at runtime, from start() to
stop(). Support of raw formats in the camera configuration is split to a
subsequent change to ease review.
In raw mode, the ISP is bypassed. There is no need to provide parameter
buffers, and the ISP will not generate statistics. This requires
multiple changes in the buffer handling:
- The params and stats buffers don't need to be allocated, and the
corresponding video nodes don't need to be started or stopped.
- The IPA module fillParamsBuffer() operation must not be called in
queueRequestDevice(). As a result, the IPA module thus doesn't emit
the paramsBufferReady signal. The main and self path video buffers
must thus be queued directly in queueRequestDevice().
- The tryCompleteRequest() function must not to wait until the params
buffer has been dequeued.
- When the frame buffer has been captured, the IPA module
processStatsBuffer() operation must be called directly to fill request
metadata.

Unlike RkISP1Path::generateConfiguration(), the validate() function
doesn't take the camera sensor resolution into account but only
considers the absolute minimum and maximum sizes supported by the ISP to
validate the stream size. Fix it by using the same logic as when
generating the configuration.
Instead of passing the sensor resolution to the validate() function,
pass the CameraSensor pointer to prepare for subsequent changes that
will require access to more camera sensor data. While at it, update the
generateConfiguration() function similarly for the same reason.

Query the driver for the output formats and sizes that it supports,
instead of hardcoding them. This allows future-proofing for formats that
are supported by some but not all versions of the driver.
As the rkisp1 driver currently does not support VIDIOC_ENUM_FRAMESIZES,
fallback to the hardcoded list of supported formats and framesizes. This
feature will be added to the driver in parallel, though we cannot
guarantee that users will have a new enough kernel for it.

The RkISP1 can capture raw frames by bypassing the ISP. In that mode,
the ISP will not produce statistics nor consume parameters. Most
algorithms will thus be unable to run, with one exception: the AGC will
still be able to configure the sensor exposure time and analog gain in
manual mode.
To prepare for this, add the ability to disable algorithms for the
duration of the capture session based on the camera configuration.
Individual algorithms report whether they support raw formats at
construction time, and the IPA module disables algorithms in configure()
based on the stream configurations.
Disabled algorithms are skipped during the capture session in the
processStatsBuffer() operation. As the ISP doesn't produce statistics,
don't try to access the stats buffer. There is no need for similar logic
in fillParamsBuffer() as that operation won't be called for raw capture.
All algorithms report not supporting raw capture by default. Raw support
in AGC will be added separately.
The feature is implemented in the RkISP1 module without any support from
libipa at this point to avoid designing a generic API based on a single
user. This may be changed in the future.

Building libcamera as a subproject is failing when tracepoints are
enabled due to incorrectly managing the relative paths between the
source and build directory while generating tracepoint headers.
The previously used
path = output.replace('include/', '', 1)
logic is not sufficient to correctly determine the proper path when
libcamera is built as a subproject, and does not correctly handle the
relative paths, causing path to be processed as:
'subprojects/libcamera/include/libcamera/internal/tracepoints.h'.replace('include/', '', 1)
which evaluates to
'subprojects/libcamera/libcamera/internal/tracepoints.h'
so the tracepoints.h header file will try to include:
#define TRACEPOINT_INCLUDE "subprojects/libcamera/libcamera/internal/tracepoints.h"
which will fail.
Fix it by using Python's pathlib to calculate the relative path of the
output file with respect to the "include" directory of libcamera.
This has been tested with Pipewire. For non-subproject builds it should
generate the exact same path that was previously generated.

The RkISP1 pipeline and IPA module allows for the CameraSensorInfo to be
empty, probably to accommodate some sensor used in a test platform that
does not provide the mandatory libcamera requirements.
As the \todo item in the IPA reports, there is a possibility that the
received CameraSensorInfo is empty and it should be checked before
accessing it, but currently such requirement is not enforced in the
code.
This allows to assume all the test platforms in use have now
successfully moved their sensor driver to comply with the minimum
requirements and provide a populated CameraSensorInfo to the IPA.
As the safety check is not enforced, and as we don't want to allow
faulty sensors to send empty CameraSensorInfo to the IPA, remove the
\todo item in the IPA and fail hard in the pipeline handler if the
sensor does not comply with libcamera requirements.

The pipeline handler supports capturing multiple streams from the same
camera in YUV, RGB or RAW formats. The number of streams is limited by

This reverts commit 30d704732badc675f72fe73d14749669cb645c23.
It turns out that this commit causes some regressions and is in fact
unnecessary because the related commit "libcamera: v4l2_videodevice:
Guard against releasing unallocated buffers"
(a2bdff6d0b67475492ac7cf9318866b6d89a28fd) fixes the problem
completely (if the buffers were never allocated, the video device
avoids trying to free them even if the pipeline handler asks).
The reason for the regressions is that in this new (broken) scheme we
would never call clearBuffers() on all the streams if the internal
buffers were never allocated (i.e. buffersAllocated_ is never
set). This causes the stream's bufferMap_ list to get longer and
longer if there are multiple back-to-back calls to configure, and
dev_->importBuffers() will ultimately to fail.
So either we need to think more carefully about how to stop the
pipeline handler from freeing buffers that it doesn't own, or we just
leave it as the other commit resolves the problem on its own. In the
interim, simply reverting this commit certainly seems like the best
solution.

The V4L2VideoDevice ensures that all sequence numbers for applications
commence at zero from the libcamera perspective. This should be the
behaviour expected by kernel drivers, but this is not always the case.
This is handled internally to ensure consistency, and a warning is
printed if the device does not start from zero. It was expected that the
Warning would help highlight where kernel drivers should be fixed, but
this has led to several false positive reports of failures where people
have been concerned that this warning is a cause for unrelated issues.
Lower the log level print to 'Info', to reduce the apparent severity of
this warning. Info is likely more appropriate that Debug to continue to
