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.
To handle the situation when a Request underrun occours and let
algorithms initialize a FrameContext to safe defaults:
- Add an 'underrun' flag to FrameContext
- Add an 'initFrameContext()' function to RkISP1 algorithms
- If a FrameContext is get() before being allocated, pass it through
the algorithms' initFrameContext() to safely initialize it

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.

In order to pre-queue video buffers, the memory management mode of the
video device should be switched to DMABUF and the buffer cache needs to
be initialized. This is done by the V4L2VideoDevice::importBuffers()
function.
Currently the RkISP1Path class calls importBuffers() in its start()
function, preventing buffer pre-queueing before starting the video
device.
Break out the buffer import operation to a pre-queue buffer function
to allow buffer pre-queueing.

The python venv module is the standard way of creating virtual python
environments. 'venv' is a commonly used name for the corresponding
directory. For example in the tuning docs we propose to execute 'python
-m venv venv' to setup a local virtual environment. During development
I often have these scattered around in the source tree and they show up
as untracked files in git. Add venv to .gitignore to prevent that.

Commit 761545407c76 ("pipeline: rkisp1: Filter out sensor sizes not
supported by the pipeline") introduced a mechanism to determine maximum
supported sensor resolution and filter out resolutions that cannot be
supported by the ISP.
However, it missed to update the raw stream configuration path, where
it should have clamped the raw stream configuration size to the maximum
sensor supported resolution.
This patch fixes the above issue and can be confirmed with IMX283

Integrate the RkISP1 pipeline handler to support sensor configuration
provided by applications through CameraConfiguration::sensorConfig.
The SensorConfiguration must be validated on both RkISP1Path (mainPath
and selfPath), so the parameters of RkISP1Path::validate() have been
updated to include sensorConfig.
The camera configuration will be marked as invalid when the sensor
configuration is supplied, if:
- Invalid sensor configuration (SensorConfiguration::isValid())
- Bit depth not supported by RkISP1 pipeline
- Sensor configuration output size is larger than maximum supported
sensor's size on RkISP1 pipeline
- No matching sensor configuration output size supplied by the sensor

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.

Support for DNG capture is conditioned by the availability of libtiff,
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.

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

> 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

Use the standard libcamera mechanism to report the "current" controls
rather than delaying updates by counting from the last update.
A problem is that with software ISP we cannot be sure about the sensor
delay. The original implementation simply skips exposure updates for 2
frames, which should be enough in most cases. After this change, we
assume the delay being exactly 2 frames, which may or may not be correct
and may work with outdated values if the delay is shorter.
According to Kieran, the wrong parts are also wrong on the
IPU3/RKISP1/Mali pipelines and only RPi have this correct. We need to
fix this, by correctly specifying the gains in the libipa camera sensor
helpers. The sooner the better because this change could introduce a
risk of increasing oscillations.
This patch also prepares moving exposure+gain to an algorithm module
where the original delay mechanism would be a (possibly unnecessary)
complication.

It's more natural to represent color gains as floating point numbers
rather than using a particular pixel-related representation.
double is used rather than float because it's a more common floating
point type in libcamera algorithms. Otherwise there is no obvious
reason to select one over the other here.
The constructed color tables still use integer representation for
efficiency.
Black level still uses pixel (integer) values, for consistency with

After black level handling has been moved to an algorithm module, white
balance and the construction of color tables can be moved to algorithm
modules too.
This time, the moved code is split between stats processing and
parameter construction methods. It is also split to two algorithm
modules:
- White balance computation.
- Gamma table computation and color lookup tables construction. While
this applies the color gains computed by the white balance algorithm,
it is not directly related to white balance. And we may want to
modify the color lookup tables in future according to other parameters
than just gamma and white balance gains.
Gamma table computation and color lookup tables construction could be
split to separate algorithms too. But there is no big need for that now
so they are kept together for simplicity.
This is the only part of the software ISP algorithms that sets the
parameters so emitting setIspParams can be moved to prepare() method.
A more natural representation of the gains (and black level) would be
floating point numbers. This is not done here in order to minimize
changes in code movements. It will be addressed in a followup patch.

The black level determination, already present as a separate class, can
be moved to the prepared Algorithm processing structure. It is the
first of the current software ISP algorithms that is called in the stats
processing sequence, which means it is also the first one that should be
moved to the new structure. Stats processing starts with calling
Algorithm-based processing so the call order of the algorithms is
retained.
Movement of this algorithm is relatively straightforward because all it
does is processing stats.
The comment about getting black level from the tuning files is dropped.
The black level will be taken from CameraSensorHelper if available and
that will be implemented in one of the followup patches.
Black level is now recomputed on each stats processing. In a future
patch, after DelayedControls are used, this will be changed to recompute
the black level only after exposure/gain changes.
The black level depends on the sensor used, the computed value can be
reused in a followup capture sessions with the same sensor. Thus it is
sufficient to (re)set the initial value in BlackLevel::init.

This is preparation only since there are currently no Algorithm based
algorithms defined.
A part of this change is passing IPAConfigInfo instead of ControlInfoMap
to configure() calls as this is what Algorithm::configure expects.

We are ready to introduce algorithms now. First, let's create
algorithms. The algorithms are not called yet, calls to them will be
added in followup patches.
The maximum number of contexts is set to the same value as in hardware
pipelines.

A previous preparation patch implemented passing frame ids to stats
processing but without actual meaningful frame id value passed there.
This patch extends that by actually providing the frame id and passing
it through to the stats processor.
The frame id is taken from the request sequence number, the same as in
hardware pipelines.

The policy and the style checker require that \brief, \param and \return
texts don't finish with a dot. This needs to be fixed in debayer.cpp.
Also leading spaces in a \return statement are removed from there.

This patch adds frame and bufferId arguments to stats related calls.
Although the parameters are currently unused, because frame ids are not
tracked and used and the stats buffer is passed around directly rather
than being referred by its id, they bring the internal APIs closer to
their counterparts in hardware pipelines.
It serves as a preparation for followup patches that will introduce:
- Frame number tracking in order to switch to DelayedControls
(software ISP TODO #11 + #12).
- A ring buffer for stats in order to improve passing the stats
(software ISP TODO #2).
Frame and buffer ids are unrelated for the given purposes but since they
are passed together at the same places, the change is implemented as a
single patch rather than two, basically the same, patches.

Software ISP image processing algorithms are currently defined in a
simplified way, different from other libcamera pipelines. This is not
good for several reasons:
- It makes the software ISP code harder to understand due to its
different structuring.
- Adding more algorithms may make the code harder to understand
generally.
- Mass libcamera code changes may not be easily applicable to software
ISP.
- Algorithm sharing with other pipelines is not easily possible.
This patch introduces basic software ISP IPA skeletons structured
similarly to the other pipelines. The newly added files are currently
not used or compiled and the general skeleton structures don't contain
anything particular. It is just a preparation step for a larger
refactoring and the code will be actually used and extended as needed in
followup patches.
