08d7e66df0 ipa: rkisp1: Split queuing of request and parameter filling
Queuing of request (i.e. passing of controls to the IPA)
and filling of the parameters buffer are two separate operations.
Treat them as such by splitting them into two functions in
the rkisp1 IPA interface.

c7d4599565 ipa: rkisp1: Replace event-based ops with dedicated functions
The IPARkISP1Interface currently uses event-type based structures in
order to communicate with the pipeline-handler (and vice-versa).
Replace the event based structures with dedicated functions associated
to each operation.

The translated naming scheme of operations to dedicated functions:
  ActionV4L2Set         => setSensorControls
  ActionParamFilled     => paramsBufferReady
  ActionMetadata        => metdataReady
  EventSignalStatBuffer => processStatsBuffer()
  EventQueueRequest     => queueRequest()

The lexical of IPARkISP1::metadataReady() will now conflict with the
metadataReady Signal being introduced in this patch as part of the
interface change. Hence, rename IPARkISP1::metadataReady() to
IPARkISP1::prepareReady() to prevent the conflict.

4c1fc33d8a libcamera: ipu3: Drop entityControls map
The IPA::configure() function has an IPAConfigInfo parameters which
contains a map of numerical indexes to ControlInfoMap instances.

This is a leftover of the old IPA protocol, where it was not possible to
specify a rich interface as it is possible today and each entity
ControlInfoMap was indexed by a numerical id and stored in a map.

Now that the IPA interface allows to specify parameters by name, drop the
map and send the sensor's control info map only.

If we'll need more ControlInfoMap to be shared with the IPA, a new parameter
can be added to IPAConfigInfo.

c2437e8cde ipa: vimc: Send and retrieve FrameBuffers from IPA
Plumb through VIMC mojo interface to enable buffers passing.
VIMC does not have parameters or statistics buffers but we can
mimick the typical case of passing IPA buffers from pipeline
handler to IPA using mock buffers. The mock IPA buffers are
FrameBuffers which are dmabuf backed (in other words, mmap()able
through MappedFramebuffer inside the IPA).

This commits shows:
- Passing the parameter buffer from the pipeline handler to
  the IPA through functions defined in mojom interface.
- Passing request controls ControlList to the IPA.

Any tests using VIMC will now loop in the IPA paths. Any tests running
in isolated mode will help us to test IPA IPC code paths especially
around (de)serialization of data passing from pipeline handlers to the
IPA. Future IPA interface tests can simply extend the vimc mojom
interface to achieve/test a specific use case as required.

11fe4333c5 libcamera: ipu3: Initialize controls in the IPA
All the IPU3 Camera controls are currently initialized by the pipeline
handler which initializes them using the camera sensor configuration and
platform specific requirements.

However, some controls are better initialized by the IPA, which might,
in example, cap the exposure times and frame duration to the constraints
of its algorithms implementation.

Also, moving forward, the IPA should register controls to report its
capabilities, in example the ability to enable/disable 3A algorithms on
request.

Move the existing controls initialization to the IPA, by providing
the sensor configuration and its controls to the IPU3IPA::init()
function, which initializes controls and returns them to the pipeline
through an output parameter.

The existing controls initialization has been copied verbatim from the
pipeline handler to the IPA, if not a for few line breaks adjustments
and the resulting Camera controls values are not changed.

62c82ab93f libcamera: controls: Use ControlIdMap in deserialization
Introduce a new field in the controls serialization protocol to
allow discerning which ControlIdMap a ControlInfoMap refers to.

The newly introduced IdMapType enumeration describes the possible
info maps:
- Either the globally available controls::controls and
  properties::properties maps, which are valid across IPC boundaries
- A ControlIdMap created locally by the V4L2 device, which is not valid
  across the IPC boundaries

At de-serialization time the idMapType field is inspected and
- If the idmap is a globally defined one, there's no need to create
  new ControlId instances when populating the de-serialized
  ControlInfoMap. Use the globally available map to retrieve the
  ControlId reference and use it.
- If the idmap is a map only available locally, create a new ControlId
  as it used to happen before this patch.

As a direct consequence, this change allows us to perform lookup by
ControlId reference on de-serialized ControlIdMap that refers to the
libcamera defined controls::controls and properties::properties.

b48db3c489 libcamera: controls: Create ControlInfoMap with ControlIdMap
ControlInfoMap does not have a ControlId map associated, but rather
creates one with the generateIdMap() function at creation time.

As a consequence, when in the need to de-serialize a ControlInfoMap all
the ControlId it contains are created by the deserializer instance, not
being able to discern if the controls the ControlIdMap refers to are the
global libcamera controls (and properties) or instances local to the
V4L2 device that has first initialized the controls.

As a consequence the ControlId stored in a de-serialized map will always
be newly created entities, preventing lookup by ControlId reference on a
de-serialized ControlInfoMap.

In order to make it possible to use globally available ControlId
instances whenever possible, create ControlInfoMap with a reference to
an externally allocated ControlIdMap instead of generating one
internally.

As a consequence the class constructors take and additional argument,
which might be not pleasant to type in, but enforces the concepts that
ControlInfoMap should be created with controls part of the same id map.

As the ControlIdMap the ControlInfoMap refers to needs to be allocated
externally:
- Use the globally available controls::controls (or
  properties::properties) id map when referring to libcamera controls
- The V4L2 device that creates ControlInfoMap by parsing the device's
  controls has to allocate a ControlIdMap
- The ControlSerializer that de-serializes a ControlInfoMap has to
  create and store the ControlIdMap the de-serialized info map refers to

6449590b63 ipa: mojom: Move CameraSensorInfo struct exclusively to IPA IPC
CameraSensorInfo structure is designed to pass in camera sensor related
information from pipeline-handler to IPA. Since the pipeline-handler
and IPA are connected via mojom IPC IPA interface, the interface
itself provides a more suitable placement of CameraSensorInfo,
instead of camera_sensor.h (which is a libcamera internal header
ultimately, at this point).

As CameraSensorInfo is already defined in core.mojom, it is just
a matter of removing [skipHeader] tag to allow code-generation
of CameraSensorInfo.

Finally, update header paths to include CameraSensorInfo definition
from IPA interfaces instead of "libcamera/internal/camera_sensor.h".

Put core.mojom in the libcamera namespace, as all structs that are

17e8f6f71c utils: ipc: Include instead of forward-declare CameraSensorInfo
For structs defined in core.mojom that have the skipHeader tag, if
they're only used in function parameters (in a mojom file) then a
forward-declaration is sufficient. However, if the struct is used in
another struct in a mojom file, then the forward-declaration is
insufficient, and the definition needs to be included. Do so for
CameraSensorInfo, which is the only forward-declared struct in
ipa_interface.h, and update the documentation comment.

Move the opening of the CamHelper from ipa::configure() to ipa::init().
This allows the pipeline handler to get the sensor specific parameters

e32d33b11d ipa: rkisp1: Fail on init if hw revision is not RKISP1_V10
In kernel 5.11 the rkisp1 uapi had changed to support different hardware
revisions. Currently only revision 10 is supported by the rkisp1 IPA and
therefore 'init' should fail if the revision is not 10.

This changes depends on the kernel driver reporting the hardware
revision, and thus requires the rkisp1 driver from v5.11 or newer.

cd07b604ba pipeline: ipa: raspberrypi: Pass exposure/gain values to IPA though controls
When running with sensors that had no embedded data, the pipeline handler
would fill a dummy embedded data buffer with gain/exposure values, and
pass this buffer to the IPA together with the bayer buffer. The IPA would
extract these values for use in the controller algorithms.

Rework this logic entirely by having a new RPiCameraData::BayerFrame
queue to replace the existing bayer queue. In addition to storing the
FrameBuffer pointer, this also stores all the controls tracked by
DelayedControls for that frame in a ControlList. This includes include
exposure and gain values. On signalling RPi::IPA_EVENT_SIGNAL_ISP_PREPARE
IPA event, the pipeline handler now passes this ControlList from the
RPiCameraData::BayerFrame queue.

The IPA now extracts the gain and exposure values from the ControlList
instead of using RPiController::MdParserRPi to parse the embedded data
buffer.

6e65d42257 libcamera: Enable vimc pipeline handler when tests are enabled
The addition of the new IPA IPC mechanism compiles pipeline-specific
headers to define the interface between the pipeline and the IPA.

This was optimised in 08ce394465 ("meson: ipa, proxy: Only build
proxies for enabled pipelines") to only build for enabled pipelines,
however the tests directly use the VIMC pipeline handler, and require
it to be built.

Create a local variable to store the requested pipelines from the user
configuration and extend the enabled pipelines to ensure that VIMC is
always enabled if the tests are also enabled

Fixes: 08ce394465 ("meson: ipa, proxy: Only build proxies for enabled pipelines")
