3ffaa4c0e2 libcamera: ipa: simple: Remove Lut algorithm
The Lut algorithm is not really an algorithm.  Moreover, algorithms may
be enabled or disabled but with Lut disabled, nothing will work.

Let's move the construction of lookup tables to CPU debayering, where it
is used.  The implied and related changes are:

- DebayerParams is changed to contain the real params rather than lookup
  tables.
- contrastExp parameter introduced by GPU ISP is used for CPU ISP too.
- The params must be initialised so that debayering gets meaningful
  parameter values even when some algorithms are disabled.
- combinedMatrix must be put to params everywhere where it is modified.
- Matrix changes needn't be tracked in the algorithms any more.
- CPU debayering must watch for changes of the corresponding parameters
  to update the lookup tables when and only when needed.
- Swapping red and blue is integrated into lookup table constructions.
- gpuIspEnabled flags are removed as they are not needed any more.

cfdc281100 libcamera: control_serializer: Add array info to serialized ControlValue
Array controls (eg. ColourCorrectionMatrix, FrameDurationLimits,
ColourGains) are serialized properly by the ControlSerializer, but are
not deserialized properly. This is because their arrayness and size are
not considered during deserialization.

Fix this by adding arrayness and size to the serialized form of all
ControlValues. This is achieved by fully serializing the min/max/def
ControlValue's metadata associated with each ControlInfo entry in the
ControlInfoMap.

While at it, clean up the serialization format of ControlValues and
ControlLists:
- ControlValue's id is only used by ControlList, so add a new struct for
  ControlList entries to contain it, and remove id from ControlValue
- Remove offset from ControlInfo's entry, as it is no longer needed,
  since the serialized data of a ControlInfo has now been converted to
  simply three serialized ControlValues
- Remove the type from the serialized data of ControlValue, as it is
  already in the metadata entry

The issue regarding array controls was not noticed before because the
default value of the ControlInfo of other array controls had been set to
scalar values similar to how min/max are set, and ColourCorrectionMatrix
was the first control to properly define a non-scalar default value.

2cc66bb547 libcamera: mali-c55: Set bytesused appropriately
At the moment the mali-c55 pipeline handler sets bytesused for a
buffer to be the maximum possible size (i.e. the size of a struct
mali_c55_params_buffer). This is not really in keeping with the goal
of the extensible parameters formats, and will not work with the new
framework for those formats. Update the IPA module and pipeline
handler to set bytesused to the size of the parameters that were
actually supplied rather than the maximum possible size.

Replace the dropFrameCount parameter returned from ipa::start() to the

485a807dcb ipa: simple: Report exposure in metadata
Report exposure and gain in metadata.

This is more complicated than it could be expected because the exposure
value should be in microseconds but it's handled using V4L2_CID_EXPOSURE
control, which doesn't specify the unit, see
https://www.kernel.org/doc/html/latest/userspace-api/media/v4l/control.html.
So the unit conversion is done in the way rkisp1 IPA uses.

This requires getting and passing IPACameraSensorInfo around.  To avoid
naming confusion and to improve consistency with rkisp1 IPA,
sensorCtrlInfoMap parameter is renamed to sensorControls.

ac30686556 libcamera: software_isp: Track whether CCM is enabled
Applying color correction matrix (CCM) in software ISP is optional due
to performance reasons.  CCM is applied if and only if `Ccm' algorithm
is present in the tuning file.

Software ISP debayering is a performance critical piece of code and we
do not want to use dynamic conditionals there.  Therefore we pass
information about CCM application to debayering configuration and let it
select the right versions of debayering functions using templates.  This
is a trick similar to the previously used one for adding or not adding
an alpha channel to the output.

Debayering gets this information but it ignores it in this patch.
Actual processing with CCM is added in the followup patch.

d0478c41f4 libcamera: Rename "shutter speed" to "exposure time"
The terms "shutter" and "shutter speed" are used through libcamera to
mean "exposure time". This is confusing, both due to "speed" being used
as "time" while it should be the inverse (i.e. a maximum speed should
correspond to the minimum time), and due to "shutter speed" and
"exposure time" being used in different places with the same meaning.

To improve clarity of the code base and the documentation, use "exposure
time" consistently to replace "shutter speed".

This rename highlighted another vocabulary issue in libcamera. The
ExposureModeHelper::splitExposure() function used to document that it
splits "exposure time into shutter time and gain". It has been reworded
to "split exposure into exposure time and gain". That is not entirely
satisfactory, as "exposure" has a defined meaning in photography (see
https://en.wikipedia.org/wiki/Exposure_(photography)) that is not
expressed as a duration. This issue if left to be addressed separately.

8fceb6ab1d libcamera: Rationalize IPA and handlers names
The names used by the IPA interface and the names used for buffer
completions handlers in libcamera clash in the use of the term "buffer".

For example video device buffer completion handler is called
"bufferReady" and the IPA event to ask the IPA to compute parameters are
called "fillParamsBuffers". This makes it hard to recognize which
function handles video device completion signals and which ones handle
the IPA interface events.

Rationalize the naming scheme in the IPA interface function and events
and the signal handlers in the pipelines,  according to the
following table. Remove the name "buffer" from the IPA interface events
and events handler and reserve it for the buffer completion handlers.
Rename the IPA interface events and function to use the 'params' and
'stats' names as well.

IPA Interface:

- fillParamsBuffer -> computeParams   [FUNCTION]
- processStatsBuffer -> processStats  [FUNCTION]
- paramFilled -> paramsComputed       [EVENT]

Pipeline handler:

- bufferReady -> videoBufferReady     [BUFFER HANDLER]
- paramReady -> paramBufferReady      [BUFFER HANDLER]
- statReady -> statBufferReady        [BUFFER HANDLER]
- paramFilled -> paramsComputed       [IPA EVENT HANDLER]

Cosmetic change only, no functional changes intended.

c64f2f197a libcamera: software_isp: Make stats frame and buffer aware
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.

cca55c83f5 libcamera: software_isp: Define skeletons for IPA refactoring
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.

a5f12d2eb3 meson: utils: Provide environment for Python scripts
Python scripts run as part of the build process need to take a few
actions specific to the environment in which they operate. One of those
is disabling the Python bytecode cache, to avoid writing .pyc files to
the source tree. This is done manually in the IPC generate.py and
parser.py scripts.

The current implementation is not ideal because it hardcodes in the
scripts information related to the environment in which they operate. As
those scripts are part of libcamera this is more of a theoretical issue
than a practical one. A second issue is that future Python scripts will
need to duplicate similar mechanisms, resulting in a higher maintenance
burden.

Address the issue with a different approach, by creating a meson
environment for the Python scripts, and passing it to the
custom_target() functions. The environment only disables the bytecode
cache for now.

The diffstat shows an increase in code size. This is expected to be
offset by usage of the environment for more Python scripts, as well as
support of more variables in the environment.

e317eaf072 ipa: ipa_interface: Declare ipaCreate() in libcamera namespace
The ipaCreate() function is the entry point to IPA modules. It is
declared in ipa_interface.h, and defined by each module. As the function
is defined with extern "C" linkage, the namespace in which it is
contained is not very relevant from a caller's point of view. For the
IPA module implementer, however, defining the function in the libcamera
namespace avoids adding an explicit libcamera:: prefix to the symbols
used by the function. This is why all IPA modules define their
ipaCreate() entry point in the libcamera namespace.

The ipa_interface.h file, however, declares the function in the global
namespace. This doesn't cause any issue at runtime, but will cause a
missing declaration warning when we enable them. To prepare for that,
move the function declaration to the libcamera namespace.

626172a16b libcamera: Drop file name from header comment blocks
Source files in libcamera start by a comment block header, which
includes the file name and a one-line description of the file contents.
While the latter is useful to get a quick overview of the file contents
at a glance, the former is mostly a source of inconvenience. The name in
the comments can easily get out of sync with the file name when files
are renamed, and copy & paste during development have often lead to
incorrect names being used to start with.

Readers of the source code are expected to know which file they're
looking it. Drop the file name from the header comment block.

The change was generated with the following script:

----------------------------------------

dirs="include/libcamera src test utils"

declare -rA patterns=(
	['c']=' \* '
	['cpp']=' \* '
	['h']=' \* '
	['py']='# '
	['sh']='# '

for ext in ${!patterns[@]} ; do

	for file in $files ; do
		name=$(basename ${file})

This misses several files that are out of sync with the comment block
header. Those will be addressed separately and manually.

Define the Soft IPA main and event interfaces, add the Soft IPA
implementation.

The current src/ipa/meson.build assumes the IPA name to match the
pipeline name. For this reason "-Dipas=simple" is used for the
Soft IPA module.

Auto exposure/gain and AWB implementation by Dennis, Toon and Martti.

Auto exposure/gain targets a Mean Sample Value of 2.5 following
the MSV calculation algorithm from:
https://www.araa.asn.au/acra/acra2007/papers/paper84final.pdf

Use CameraSensorHelper to convert the analogue gain code read from the
camera sensor into real analogue gain value. In the future this makes
it possible to use faster AE/AGC algorithm. Right now the CameraSensorHelper
lets us use the full range of analogue gain values.

If there is no CameraSensorHelper for the camera sensor in use, a
warning log message is printed.

2ec7f2fede build: ipa: Fix bug in building multiple IPA interfaces with the same mojom file
In the existing meson scripts, an IPA mojom interface file may not be
built if:

- There are duplicate entries for the mojom file shared by different
  pipeline handlers in pipeline_ipa_mojom_mapping, and
- The IPA is not listed first in pipeline_ipa_mojom_mapping, and
- The first listed IPA for the given mojom file is not selected in the
  build.

Fix this by using a separate list of already built mojom files
(mojoms_built) instead of overloading use of the existing
ipa_mojom_files list.  Now, ipa_mojom_files gets filled in outside of
the IPA list enumeration loop, this also guarantees the IPA
documentation gets built even if the pipeline is not selected.

The RkISP1 implementation of IPA::configure() still uses the legacy
interface where sensor controls (and eventually lens controls) are
passed from the pipeline handler to the IPA in a map.

Since the introduction of mojom-based IPA interface definition, it is
possible to define custom data types and use them in the interface
definition between the pipeline handler and the IPA.

Align the RkISP1 IPA::configure() implementation with the one in the
IPU3 IPA module by using a custom data type instead of relying on a map
to pass controls to the IPA.
