Implement the flush() camera operation in the CameraDevice class
and make it available to the camera framework by implementing the
operation wrapper in camera_ops.cpp.
Introduce a new camera state State::Flushing to handle concurrent
flush() and process_capture_request() calls.
As flush() can race with processCaptureRequest() protect it
by introducing a new State::Flushing state that
processCaptureRequest() inspects before queuing the Request to the
Camera. If flush() is in progress while processCaptureRequest() is
called, return the current Request immediately in error state. If
flush() has completed and a new call to processCaptureRequest() is
made just after, start the camera again before queuing the request.

With the introduction of an additional mutex class member, the name of

Rename CameraDevice::mutex_ in CameraDevice::descriptorsMutex_ and use the
libcamera provided libcamera::Mutex type to align the style with the

Guard access to the camera state and the start/stop sequences
with a mutex.
Currently only stop() and the first call to processCaptureRequest()
start and stop the camera, and they're not meant to race with each
other. With the introduction of flush() the camera can be stopped
concurrently to a processCaptureRequest() call, hence access to the
camera state will need to be protected.
Prepare for that by guarding the existing paths with a mutex.

The CameraDevice class uses std::scoped_lock<> to guard access to the
class' descriptors_ member.
std::scoped_lock<> provides a set of features that guarantees safety
when locking multiple mutexes in a critical section, while for single
locks happening in a scoped block it does not provides benefits compared
to the simplest std::unique_lock<> which libcamera provides the
MutexLocker type for.
Replace usage of std::scoped_lock<> with libcamera::MutexLocker to make
the implementation consistent with the rest of the code base.

The CameraDevice class maintains the camera state in the 'running_'
boolean flag to check if the camera has to be started at the first
received process_capture_request() call which happens after the camera
had been stopped.
So far this was correct, as the operations that change the camera
could only start or stop the camera, so a simple boolean flag
was enough.
To prepare to handle the flush() operation that will introduce a new
'flushing' state, replace the simple plain boolean flag with an
enumeration of values that define the CameraState.

Capture requests are queued by the PipelineHandler base class to each
pipeline handler implementation using the virtual queueRequestDevice()
function.
However, if the pipeline handler fails to queue the request to the
hardware, the request gets silently deleted from the list of queued
ones, without notifying application of the error.
Reporting to applications that a Request has failed to queue by
cancelling and then completing it allows applications to maintain their
request-tracking mechanism consistent with the one internal to the library.

The current implementation of CameraDevice::requestComplete() which
handles event notification and calls the framework capture result
callback does not handle error notification precisely enough.
In detail:
- Error notification is an asynchronous callback that has to be notified
to the framework as soon as an error condition is detected, and it
independent from the process_capture_result() callback
- Error notification requires the HAL to report the precise error cause,
by specifying the correct CAMERA3_MSG_ERROR_* error code.
The current implementation only notifies errors of type
CAMERA3_MSG_ERROR_REQUEST at the end of the procedure, before the
callback invocation.
Rework the procedure to:
- Notify CAMERA3_MSG_ERROR_DEVICE and perform library tear-down in case
a Fatal error is detected
- Notify CAMERA3_MSG_ERROR_REQUEST if the libcamera::Request::status is
different than RequestCompleted and immediately call
process_capture_result() with all buffers in error state.
- Notify the shutter event as soon as possible
- Notify CAMERA3_MSG_ERROR_RESULT in case the metadata cannot be
generated correctly and call process_capture_result() with the right
buffer state regardless of metadata availability.
- Notify CAMERA3_MSG_ERROR_BUFFER for buffers whose post-processing
failed
While at it, return the CameraStream buffer by calling
cameraStream->putBuffer() regardless of the post-processing result.
No regression detected when running CTS in LIMITED mode.

Frame duration is hard-coded for CTS as per [1]. Ideally, to accurately
calculate the frame duration, it needs the VBLANK value from every
frame's exposure. However, this particular bit is yet to be implemented
in IPAIPU3.
Meanwhile, we can at least head in the right direction by not hard
coding the value, instead using the default VBLANK value as reported
by the sensor. Update the existing \todo, to use the derived VBLANK
value as and when it's available from each frame exposure.

The return value from generateConfiguration() was not checked. Only assert
was added as a guard which checked if the size of the generated camera
config was equal to size of roles passed to it.
If the roles variable has an invalid/unsupported role, it will return
a nullptr and then trying to access a member on a nullptr for size comparison
will result in a segmentation fault. So, if the function returns a nullptr,
simply push an error message on GstBus and gracefully exit.

The mojo parser is fine if there are types that are used in array/map
members that it does not know about. These are usually caught by the C++
compiler, because the generated code refers to unknown types. This
feature is necessary for us for supporting FrameBuffer::Plane as an
array/map member, since as long as the type has an IPADataSerializer and
the struct defined in C++, the generated code will run fine
(FrameBuffer::Plane is not defined anywhere in mojom but is used as an
array member in IPABuffer).
The types that are defined in controls.h (or any header included in
ipa_interface.h) will all be compiled by the C++ compiler fine, since
the generated files all include controls.h. The types that are there
that are not ControlInfoMap or ControlList (like ControlValue) will
still fail at the linker stage. For example:
struct A {
array<ControlValue> a;
};
will compile fine, but will fail to link, since
IPADataSerializer<ControlValue> doesn't exist. This behavior, although
not the best, is acceptable.
The issue is that if ControlInfoMap or ControlList are used as array/map
members without the libcamera prefix, the compiler will not complain, as
the types are valid, and the linker will also not complain, as
IPADataSerializer<ControlList> and IPADataSerializer<ControlInfoMap>
both exist. However, the code generator will not recognize them as
types that require a ControlSerializer (since mojo doesn't recognize
them, so they are different from the ones that it does recognize with
the libcamera namespace), and so the ControlSerializer will not be
passed to the serializer in the generated code. This is the cause of the
FATAL breakage:
FATAL IPADataSerializer ipa_data_serializer.cpp:437 ControlSerializer
not provided for serialization of ControlInfoMap
Since ControlInfoMap and ControlList are the only types that will run
into this issue, we solve this by simply detecting if they are used
without the prefix, and produce an error at that point in the code
generator. As the code generator stage no longer has information on the
source code file and line, we output the struct name in which the error
was found (ninja will output the file name).

Neither clang not gcc versions older than 9 complain. This seems to be

However, there's an obvious error in the code. The second while () loop
in the first part of calculateBDSHeight() modifies the bdsHeight

We need a separate control to report the nominal frame duration, but
it's also useful to report the min/max frame duration values that will
be used. Split the FrameDurations control into FrameDuration and
FrameDurationLimits respectively to support both of these.

Boolean options in the summary are printed as 'True' or 'False' by
default. Enable the bool_yn option, which prints them as 'YES' or 'NO',
in green and red respectively. This makes the summary more readable.

Originally CameraHalManager is created in the libcamera start up
and destroyed in the libcamera termination. However,
CameraHalManager destructor can access other static objects that
has been destroyed.
Avoid this issue by destroying CameraHalManager when tear_down() is
called in ChromeOS or leaking it in other platforms.

The recent merge (and revert) of commit 34bee5e84ecb ("libcamera:
V4L2Device: Remove the controls order assumption in updateControls()")
showed that 64-bit controls were missing from unit tests.
Fix this by testing the VIVID_CID_INTEGER64 control in the V4L2 video
device controls test.

Pass in frame timestamps from IPU3 pipeline handler to IPU3 IPA via
IPU3Event. Frame timestamps are helpful to IPA algorithms to
convergence, by setting them via IPA stats.

The ControlInfoMap of entityControls member in IPAConfigInfo struct,
was not able to correctly match to the ControlInfoMap defined in
core.mojom. This resulted in a FATAL breakage when IPU3 IPA is meant to
run:

On gcc versions older than 9, the file system library, used by the
Android camera HAL configuration file parser, is implemented in a
separate static library. Furthermore, on gcc 7, it's provided in the
std::experimental namespace. This breaks compilation of the HAL on gcc
7, and linking on gcc 8.
Fix the compilation issue by conditionally including
<experimental/filesystem> and creating a namespace alias in std, and the
link issue by linking to libstdc++fs on gcc versions older than 9.
The inclusion of <experimental/filesystem> is a bit of a hack, and when
we'll start using the file system library in another compilation unit,
we should then move all this to an internal helper to abstract the
compiler version.
