The RkISP1 AGC algorithms assumes the metering mode to be
"MeteringMatrix" and pre-fill an array of weights associated
with it stored in meteringModes_[MeteringMatrix] when intializing
the algorithm in parseMeteringModes().
It laters fetches the weights when computing parameters using the
FrameContext.agc.meteringMode as index of the meteringModes_ array.
When a Request gets queued to the algorithm, the
FrameContext.agc.meteringMode index is populated from the algorithm's
active state, and optionally updated if the application has specified
a different metering mode.
In case of Request underrun however, a non-initialized FrameContext
gets provided to the algorithm, causing an (unhandled) exception when
accessing the meteringModes_ array.
Fix this by intializing the AGC metering mode to a supported value
coming from the ActiveState in IPAFrameContext::init().

Pass to the FCQueue the algorithm's active state to use the most
recent state of IPA algorithms to initialize a FrameContext.
Modify all IPA modules that use libipa to pass a const ActiveState
reference to the FCQueue function and make their IPAActiveState
implementation derive a base ActiveState structure.

Some IPA modules, like the RkISP1 one, call FCQueue::get(0) at
IPA::start() time, before any frame context has been allocated with
FCQueue::alloc() called at queueRequest() time.
The FCQueue implementation aims to detect when a FrameContext is get()
before it is alloc()-ated, Warns about it, and initializes the
FrameContext before returning it.
In case of frame#0, a get() preceding an alloc() call is not detected
as the "frame == frameContext.frame" test returns success, as
FrameContexts are zeroed by default.
As a result, the first returned FrameContext is not initialized.
Explicitly test for frame#0 to make sure the FrameContext is initialized
if get(0) is called before alloc(0). To avoid re-initializing a frame
context, in case alloc() has been called correctly before get(),
introduce an "initialised" state variable that tracks the FrameContext
initialisation state.

The FCtQueue structure initializes a new FrameContext using its init()
function. In case of request underrun, where a FrameContext is
initialized without application's controls being supplied, the
FrameContext needs to be initialized to default values.
In order to allow the single IPAs to initialize a FrameContext to
the desired default values, move the init() function to the FrameContext
structure, which each IPA derives to a per-IPA type.
In this way each IPA can override the FrameContext::init() function
and initialize the FrameContext to the desired default values.

Plumb the dw100 dewarper as a V4L2M2M converter in the rkisp1 pipeline
handler. If the dewarper is found, it is instantiated and buffers are
exported from it, instead of RkISP1Path. Internal buffers are allocated
for the RkISP1Path in case where dewarper is going to be used.
The RKISP1 pipeline handler now supports scaler crop control through
the converter. Register the ScalerCrop control for the cameras created
in the RKISP1 pipeline handler.

Currently the rkisp1 pipeline handler only registers controls that are
related to the IPA. This patch prepares the rkisp1 pipeline-handler to
register camera controls which are not related to the IPA.
Hence, introduce an additional ControlInfoMap for IPA controls. These
controls will be merged together with the controls in the pipeline
handler (introduced subsequently) as part of updateControls() and
together will be registered during the registration of the camera.
This is similar to what IPU3 pipeline handler handles its controls.

If the converter has cropping capability on its input, the interface
should support it by providing appropriate virtual functions. Provide
Feature::InputCrop in Feature enumeration for the same.
Provide virtual setInputCrop() and inputCropBounds() interfaces so that
the converter can implement its own cropping functionality.
The V4L2M2MConverter implements these interfaces of the Converter
interface. Not all V4L2M2M converters will have cropping ability
on its input, hence it needs to be discovered at construction time.
If the capability to crop is identified successfully, the cropping
bounds are determined during configure() time.

This patch allows obtaining a black level from a tuning file in addition
to the camera sensor helper. If both of them define a black level, the
one from the tuning file takes precedence.
The use cases are:
- A user wants to use a different black level, for whatever reason.
- There is a sensor without known gains but with a known black level.
Because a camera sensor helper cannot be defined without specifying
gains, the only way to specify the black level is using the tuning
file. Software ISP uses its fallback gain handling in such a case.

The 'found' flag was mistakenly understood that a compatible sensor
format has been found when a sensor configuration is passed in. However,
'found' related to the stream configuration's pixelformat, whether it is
supported by the RkISP1Path video node or not. It does not relate to the
sensor format, hence the check:
if (sensorConfig && !found)
doesn't make sense.
Rectify the above check with:
if (sensorConfig && !rawFormat.isValid())
to ensure a sensor format compatible with sensor configuration has been
set to rawFormat.

Commit 761545407c76 ("pipeline: rkisp1: Filter out sensor sizes not

However, it missed to update the raw stream configuration path, where

In many cases a static string literal is used as key. Thus
having the argument type be `const std::string&` is suboptimal
since an `std::string` object needs to be constructed before
the call.
C++17 introduced `std::string_view`, using which the call
can be done with less overhead, as the `std::string_view`
is non-owning and may be passed in registers entirely.
So make `YamlObject::{contains,operator[]}` take the string keys
in `std::string_view`s.
Unfortunately, that is not sufficient yet, because `std::map::find()`
takes an reference to `const key_type`, which would be `const std::string&`
in the case of `YamlParser`. However, with a transparent comparator
such as `std::less<>` `std::map::find()` is able to accept any
object as the argument, and it forwards it to the comparator.
So make `YamlParser::dictionary_` use `std::less<>` as the comparator
to enable the use of `std::map::find()` with any type of argument.

which is indicated by the HAVE_TIFF macro set by meson. The dng_writer.h
header then defines HAVE_DNG, which is used in a couple of places to
conditionally compile DNG-related code. Most of the other locations
where conditional compilation is required use HAVE_TIFF.
Using both HAVE_TIFF and HAVE_DNG is confusing. HAVE_DNG would be a
better name, but as the macro is defined in dng_writer.h, it would
require all files that need to test for DNG support to include that
header. Failure to include it (directly or indirectly) would result in
the code covered by the macro to be silently disabled.
To avoid the confusion, standardize on using HAVE_TIFF everywhere and
drop HAVE_DNG.

It is possible that the maximum sensor size (returned by
CameraSensor::resolution()) is not supported by the pipeline. In such
cases, a filter function is required to filter out resolutions of the
camera sensor, which cannot be supported by the pipeline.
Introduce the filter function filterSensorResolution() in RkISP1Path
class and use it for validate() and generateConfiguration(). The
maximum sensor resolution is picked from that filtered set of
resolutions instead of CameraSensor::resolution().

The minResolution_ and maxResolution_ limits are dynamically queried
in populateFormats() from the RkISP1Path video node. Therefore,
initializing these limits with the resizer limits in the constructor is
unnecessary.
This change allows us to remove the hard-coded max/min resolution limits
of the resizer from RkISP1Path, simplifying its constructor further.

Which is not only what many other pipeline handlers use, but also a good
lower limit when dealing with DRM and similar APIs. Even Mesas EGL and
Vulkan WSI implementations use for the reason outlined in mesa commit
992a2dbba80aba35efe83202e1013bd6143f0dba:
> When the compositor is directly scanning out from the application's buffer it
> may end up holding on to three buffers. These are the one that is is currently
> scanning out from, one that has been given to DRM as the next buffer to flip
> to, and one that has been attached and will be given to DRM as soon as the
> previous flip completes. When we attach a fourth buffer to the compositor it
> should replace that third buffer so we should get a release event immediately
> after that. This patch therefore also changes the number of buffer slots to 4
> so that we can accomodate that situation.
Given the popularity of this buffer number the bump should be unlikely
to cause problems. At the same time it may help with performance or
even work around glitches.
The previous number was introduced in commit
a8964c28c80fb520ee3c7b10143371081d41405a without mentioning a specific
reason against the change at hand.

The black level is likely to get updated, if ever, only after exposure
or gain changes. Don't compute its possible updates if exposure and
gain are unchanged.
It's probably not worth trying to implement something more
sophisticated. Better to spend the effort on supporting tuning files.
