We need to calculate the gain on the previous exposure value calculated.
Now that we initialise the exposure and gain values in configure(), we
know the initial exposure value, and we can set it before any loop is
running.

We have mixed terms between gain, analogue gain and the exposure value
gain.
Make it clear when we are using the analogue gain from the sensor, and
when we are using the calculated gain to be applied to the exposure
value to reach the target.

Until now, the algorithm makes complex assumptions when dividing the

The gains are currently set as a uint32_t while the analogue gain is
passed as a double. We also have a default maximum analogue gain of 15
which is quite high for a number of sensors.
Use a maximum value of 8 which should really be configured by the IPA
and not fixed as it is now. While at it make it a double.

When zones are used for the grey world algorithm, they are only
considered if their average green value is at least 32/255 to exclude
zones that are too dark and don't provide relevant colour information
(on the opposite side of the spectrum, saturated regions are excluded by
the ImgU statistics engine).
The algorithm requires a minimal number of zones that meet this criteria
in order to run. Now that we correct the black level, the 32/255 minimal
value is a bit high and prevents the algorithm for running in low-light
conditions. Lower the value to 16/255 to fix it.

The AWB grey world algorithm tries to find a grey value and it can't do
it on over-exposed images. To exclude those, the saturation ratio is
used for each cell, and the cell is included only if this ratio is 0.
Now that we have changed the threshold, more cells may be considered as
partially saturated and excluded, preventing the algorithm from running
efficiently.
Change that behaviour, and consider 90% as a good enough ratio.

The AGC frame context needs to be initialised correctly for the first
iteration. Until now, the IPA uses the minimum exposure and gain values
and caches those in local variables.
In order to give the sensor limits to AGC, create a new structure in
IPASessionConfiguration. Store the exposure in time (and not line
duration) and the analogue gain after CameraSensorHelper conversion.
Set the gain and exposure appropriately to the current values known to
the IPA and remove the setting of exposure and gain in IPAIPU3 as those
are now fully controlled by IPU3Agc.

We can have a saturation ratio per cell, giving the percentage of pixels
over a threshold within a cell where 100% is set to 0xff.
The parameter structure 'ipu3_uapi_awb_config_s' contains four fields to
set the threshold, one per channel.
The blue field is also used to configure the ImgU and make it calculate
the saturation ratio or not.
Set a green value saturated when it is more than 230 (90% of the maximum
value 255, coded as 8191). As this is the only channel used for AGC,
there is no need to apply it to the other ones.

The camera3_stream_buffer_t structure is meant to communicate between
the camera service and the HAL. They are short-live structures that
don't outlive the .process_capture_request() operation (when queuing
requests) or the .process_capture_result() callback.
We currently store copies of the camera3_stream_buffer_t passed to
.process_capture_request() in Camera3RequestDescriptor::StreamBuffer to
store the structure members that the HAL need, and reuse them when
calling the .process_capture_result() callback. This is conceptually not
right, as the camera3_stream_buffer_t pass to the callback are not the
same objects as the ones received in .process_capture_request().
Store individual fields of the camera3_stream_buffer_t in StreamBuffer
instead of copying the whole structure. This gives the HAL full control
of how data is stored, and properly decouples request queueing from
result reporting.

The Camera3RequestDescriptor structure stores, for each stream, the
camera3_stream_buffer_t and the libcamera FrameBuffer in two separate
vectors. This complicates buffer handling, as the code needs to keep
both vectors in sync. Create a new structure to group all data about
per-stream buffers to simplify this.
As a side effect, we need to create a local vector of
camera3_stream_buffer_t in CameraDevice::sendCaptureResults() as the
camera3_stream_buffer_t instances stored in the new structure in
Camera3RequestDescriptor are not contiguous anymore. This is a small
price to pay for easier handling of buffers, and will be refactored in

There's no need to store it in the Camera3RequestDescriptor. Build it

This requires storing the result metadata created in
CameraDevice::requestComplete() in the Camera3RequestDescriptor. A side
effect of this change is that the request metadata lifetime will match

Camera3RequestDescriptor is a utility structure that groups information
about a capture request. It can be and will be extended to preserve the
context of a capture overall. Since the context of a capture needs to
be shared among other classes (for e.g. CameraStream) having a private
definition of the struct in CameraDevice class doesn't help.
Hence, de-scope the structure so that it can be shared with other
components (through references or pointers). Splitting the structure to
a separate file will help avoiding circular dependencies when using it
through the HAL implementation.

When the camera HAL detects an out-of-order completion of a request, it
sends to the camera framework a CAMERA3_MSG_ERROR_DEVICE error.
Such error not only forces the service to close the camera as prescribed
by the camera3 specification, but in some implementation (specifically
the ChromeOS one) it causes the camera service to abort and exit.
This prevents any error messages from being printed by libcamera, as the
library gets terminated before getting to that point, and also hides the
printout of error messages that lead to out-of-order completion, making
it impossible to get from the output log what happened.
Move the call to notifyError() at the end of the error path and demote
the error message to LogLevels::Error from Fatal to let the service
implementation decide how to handle CAMERA3_MSG_ERROR_DEVICE errors.
Before this patch, when waiting on a fence fails and the capture
request is not queued to the Camera, we get an out-of-order completion
but no backtrace. With this patch applied the error path is visible:

Commit d165f7da34b8 ("android: camera_device: Configure one stream for
identical stream requests") introduced the ability to generate through
post-processing YUV streams of identical size and format.
However the change didn't fully take into account the situation
where only mapped streams are contained in the request submitted by
the camera service to the HAL. In this case the Request will be queued
with no buffers and refused by the Camera.
Even if this seems a corner case it causes a few CTS to fail, and more
problematically it triggers out-of-order completion of requests, causing
the camera service to abort.

Limit the reported minumum frame duration to 30 FPS.

to perform quality tuning in the closed-source IPA module and has been

This change bring into the HAL a platform specific constraints, which

Also record that, even if we report a lower frame rate, we currently
