When a request is given to a pipeline handler, it must parse the request
and identify what actions the pipeline handler should take to enact on hardware.
In the case of the VIVID pipeline handler, we identify the buffer from the only
supported stream, and queue it to the video capture device.

We can now add buffer management, and connect up our bufferReady signal
to a callback.
Note that we provide the ability to export buffers from our capture
device (data->video_) using the exportBuffers() functionality from the
V4L2VideoDevice which allows a FrameBufferAllocater to obtain buffers
from this device.
When buffers are obtained through the exportFrameBuffers API, they are
orphaned and left unassociated with the device, and must be reimported
at start() time anyway. This allows the same interface to be used
whether internal buffers, or external buffers are used for the stream.
When a buffer completes, we call the buffer completion handler on the
pipeline handler, and because we have only a single stream, we can also
immediately complete the request.

When the configurations have been generated and validated, they can be
applied to a device.
Vivid supports only a single stream, so it directly obtains the first
StreamConfiguration from the CameraConfiguration.
The VIVID catpure device is a V4L2Video device, so we generate a
V4L2DeviceFormat to apply directly to the capture device node.
Note that we convert the libcamera Format stored in
cfg.pixelFormat to a V4L2PixelFormat using V4L2PixelFormat helper. This
currently defaults to the single-planar formats, and should be extended
to support the Multiplanar configuration from the V4L2Device.
[todo Repair the link between the multiplanar configuration of the
V4L2VideoDevice and the pixel format selection]
Following the call to set the format using the Kernel API, if the format
has been adjusted in any way by the kernel driver, then we have failed
to correctly handle the validation stages, and thus the configure
operation is idendified has having failed.
Finally stream specific data can be directly stored and set as
reflecting the state of the stream.
[NOTE: the cfg.setStream() call here associates the stream to the
StreamConfiguration however that should quite likely be done as part of
the validation process. TBD]

Implement the support for Generating and Validating the streams the
Camera can provide.
Vivid is a simple case with only a single stream.
Test the configurations can be generated and reported with cam -I:

Cameras such as the PiCam 3 support auto-focus, but the GStreamer plugin
for libcamera does not enable auto-focus. With this patch auto-focus can
be enabled for cameras that support it. By default it is disabled, which
means default behaviour remains unchanged. For cameras that do not
support auto-focus, an error message shows up if auto-focus is enabled.
This was tested on cameras that do not support auto-focus (e.g. PiCam2)
and was tested on a camera that does support auto-focus (PiCam3). The
test involved setting the focus to AfModeContinous and observing it.
However, by not setting "auto-focus-mode" or using AfModeManual as
the "auto-focus-mode" both resulting in auto-focus being disabled.

The current implementation enumerates a single RAW format (the sensor's

CameraConfiguration has been generated for.
Fix this by:
- Enumerate RAW StreamFormats only when the requested role is
StreamRole::Raw
- Add all the sensor's provided resolutions that fit the video device
output maximum size
Before this patch, a single RAW size was enumerated in stream formats
* Pixelformat: SRGGB10 (4208x3120)-(4208x3120)/(+1,+1)
- 4208x3120
With this patch applied all sensor's supported resolutions are
enumerated but only when the stream role RAW is explicitly requested
* Pixelformat: SRGGB10 (1048x780)-(4208x3120)/(+0,+0)

Currently each RkISP1 path (main and self) generate a configuration
by bounding the sensor's resolution to their respective maximum output
aspect ratio and size.
Size maxResolution = maxResolution_.boundedToAspectRatio(resolution)
.boundedTo(resolution);
In the case of self path, whose maximum size is 1920x1920, the generated
configuration could get assigned unusual sizes, as the result of the
above operation.
As an example, with the imx258 sensor whose resolution is 4208x3118, the
resulting size for the Viewfinder use case is an unusual 1920x1423.
Fix this by assigning to each role a desired output size:
- Use the sensor's resolution for StillCapture and Raw
- Use 1080p for Viewfinder and VideoRecording

The generateConfiguration() implementation in the Rockchip RkISP1
pipeline handler uses by default the self path (if available) for
the Viewfinder and VideoRecording StreamRoles.
The validate() implementation, at the contrary, prefers using the main
path, when available, for all streams.
As the self-path is limited in output resolution to 1920x1920,
generating a configuration using the self path limits the maximum
stream size to 1920x1920, while higher resolutions can be obtained by
using the main path.
Align the generateConfiguration() implementation to the validate() one
by using the main path by default if available.

We are using pybind11 'smart_holder' branch to solve the Camera
destructor issue (see the comment in this patch, or the commit
that originally added Python bindings support).
As it would be very nice to use the mainline pybind11 (which is packaged
in distributions), this patch adds a workaround allowing us to move to
the mainline pybind11 version.
The workaround is simply creating a custom holder class
(PyCameraSmartPtr), used only for the Camera, which wraps around the
shared_ptr. This makes the compiler happy.
Moving to mainline pybind11 is achieved with:
- Change the pybind11 wrap to point to the mainline pybdind11 version
- Tell pybind11 to always use shared_ptr<> as the holder for
PyCameraManager, as we use the singleton pattern for the
PyCameraManager, and using shared_ptr<> to manage it is a requirement
- Tell pybind11 to always use PyCameraSmartPtr<> as the holder for Camera
- Change the meson.build file to use a system-installed pybind11

Which is wrong, gralloc_open() is attempting to re-open the camera HAL,
instead of the gralloc HAL.
Point to a GRALLOC_HARDWARE_MODULE_ID instead so that we can request
buffers from gralloc in android.
Note: this adds new dependencies on android's libhardware [1] and on libdl.

If a user uses a pipeline handler config file where a custom timeout
value is specified, it would lead to a segmentation fault when
loadPipelineConfiguration() tried to access the as yet uninitialised
V4L2VideoDevice object.
To fix this, parse the pipeline handler config file only after fully
initialising and registering the pipeline handler and V4L2VideoDevice
objects.

Add support for the Sony IMX327, which is added to the kernel with
commit 2d41947ec2c0 ("media: i2c: imx290: Add support for imx327
variant"). It is basically a derivate of the IMX290, therefore also
derive the helper.

As the sensor's analogue gain range is known (read-out in
IPARkISP1::configure()), drop the limiting hard-coded range.
This enables better performance in low-light conditions for sensors with
a higher gain (e.g. the imx327).

When iterating over enabled pipelines and IPA modules, libcamera
descends into subdirectories in a recursive manner, which involves
nested loops. Both the outer and inner loops use the same loop variable
named 'pipeline'. As the outer loop uses the variable after descending
into the inner directory, it ends up using an incorrect value. Fix it by
moving all use of the variable before the subdir() call, and add a
comment that warns about the issue to avoid reintroducing it.

Now that we allow IPA modules to live in nested directories for the
RaspberryPi platform, it is required to allow parsing one more level
to be able to run libcamera from the source directory.
Without this patch the $(builddir)/src/ipa/rpi/vc4/ipa_rpi_vc4.so
IPA module cannot be loaded.
The issue is only present when running from the source directory
as when libcamera is installed all IPA modules are deployed to a single
$(prefix)/$(libcamera_libdir)/libamera/ location.

Files opened internally in libcamera without the O_CLOEXEC file will
remain open upon a call to one of the exec(3) functions. As exec()
doesn't destroy local or global objects, this can lead to various side
effects. Avoid this by opening file descriptors with O_CLOEXEC for all
internal files.
The O_CLOEXEC flag should also be set when obtaining file handles from
the V4L2 VIDIOC_EXPBUF operation, but was missed during the updates to
both d942bdc913c5 ("libcamera: v4l2_device: openat(2) with O_CLOEXEC to
cleanup after exec(3)") and 436b38fd89fe ("libcamera: Open files with
O_CLOEXEC").
Set the O_CLOEXEC flag on calls to ioctl(VIDIOC_EXPBUF).

Move the v4l2-compat.so shared library installation to the libcamera
directory under libexec. This is the same location that the proxy
workers live and will facilitate easier packaging of the V4L2
compatibility layer with distributions.
Create a new libcamera_libexecdir variable within meson to simplify
representation of this path and update the proxy worker meson.build
infrastructure to make use of it as well.
