7127954aaa ipa: rpi: agc: Use channel constraints in the AGC algorithm
Whenever we run Agc::process(), we store the most recent total
exposure requested for each channel.

With these values we can apply the channel constraints after
time-filtering the requested total exposure, but before working out
how much digital gain is needed.

7927c44735 ipa: rpi: agc: Add AgcChannelConstraint class
A channel constraint is somewhat similar to the upper/lower bound
constraints that we use elsewhere, but these constraints apply between
multiple AGC channels. For example, it lets you say things like "don't
let the channel 1 total exposure be more than 8x that of channel 0",
and so on. By using both an upper and lower bound constraint, you
could fix one AGC channel always to be a fixed ratio of another.

Also read a vector of them (if present) when loading the tuning file.

beab3a229f ipa: rpi: agc: Implementation of multi-channel AGC
The switchMode, prepare and process methods are updated to implement
multi-channel AGC correctly:

* switchMode now invokes switchMode on all the channels (whether
  active or not).

* prepare must find what channel the current frame is, and run on
  behalf of that channel.

* process updates the most recent DeviceStatus and statistics for the
  channel of the frame that has just arrived, but generates updated
  values working through the active channels in round-robin fashion.

One minor detail in process is that we don't want to change the
DeviceStatus metadata of the current frame, so we now pass this to the
AgcChannel's process method, rather than letting it find the
DeviceStatus in the metadata.

b2cb498a1a ipa: rpi: agc: Reorganise code for multi-channel AGC
This commit does the basic reorganisation of the code in order to
implement multi-channel AGC. The main changes are:

* The previous Agc class (in agc.cpp) has become the AgcChannel class
  in (agc_channel.cpp).

* A new Agc class is introduced which is a wrapper round a number of
  AgcChannels.

* The basic plumbing from ipa_base.cpp to Agc is updated to include a
  channel number. All the existing controls are hardwired to talk
  directly to channel 0.

There are a couple of limitations which we expect to apply to
multi-channel AGC. We're not allowing different frame durations to be
applied to the channels, nor are we allowing separate metering
modes. To be fair, supporting these things is not impossible, but
there are reasons why it may be tricky so they remain "TBD" for now.

This patch only includes the basic reorganisation and plumbing. It
does not yet update the important methods (switchMode, prepare and
process) to implement multi-channel AGC properly. This will appear in
a subsequent commit. For now, these functions are hard-coded just to
use channel 0, thereby preserving the existing behaviour.

250565b5e8 ipa: rpi: agc: Split AgcStatus into AgcStatus and AgcPrepareStatus
The Agc::process() function returns an AgcStatus object in the
metadata as before, but Agc::prepare() is changed to return the values
it computes in a separate AgcPrepareStatus object (under the new tag
"agc.prepare_status").

The "digitalGain" and "locked" fields are moved from AgcStatus to
AgcPrepareStatus.

This will be useful going forward as we can be more flexible about the
order in which prepare() and process() are called, without them
trampling on each other's results.

f7a9f14156 v4l2: v4l2_camera_proxy: Prevent ioctl sign-extensions
Handling ioctl's within applications is often wrapped with a helper such
as xioctl. Unfortunately, there are many instances of xioctl which
incorrectly handle the correct size of the ioctl request.

This leads to incorrect sign-extension of ioctl's which have bit-31 set,
and can cause values to be passed into the libcamera's v4l2 adaptation
layer which no longer represent the true IOCTL code.

Match the implementation of the Linux kernel and ensure that only 32
bits of the ioctl request are used by assigning to an unsigned int.

A new overload is added that accepts an initializer list so that

There is no API break since a span can be constructed from a vector
and the initializer list overload takes care of the initializer lists,
but this change causes an ABI break.

e6b6a6d42e gstreamer: Drop libcamera_private dependency
Drop libcamera_private dependency entirely as to avoid libcamerasrc
getting more dependent on it. In order to achieve that, one of the
mutex locks in GstLibcameraSrcState needs to be replaced with GMutex.

However doing so, this won't let us to use the clang's thread annotation
macros in libcamera (which should be fine as libcamerasrc would move
out of libcamera repo once matured).

0d1e402e1b pipeline: rpi: Do not return an error from pipeline config file handling
If a user provided pipeline config file is not present, or if the
version reported in the file is invalid, do not return with an error
when creating the pipeline handler. Instead, log a warning message and
return success with default pipeline config values used.

This now matches the behaviour when the pipeline config file could not
be parsed correctly, and we revert to default values.

618b9aaa17 ipa: rpi: agc: Do not switch to a default if a mode is unavailable
In commit 0ee9339331, a default metering/exposure/constraint mode is
used if a control sets a mode that is not listed in the camera tuning
file.

Setting a default mode may be undesirable in these cases, so instead
keep the agc mode unchanged. This also matches the behaviour for other
IPA controls where no changes are made in error conditions.

As the CameraSensor::validateTransform() function compensate
for the sensor's mounting rotation, the properties::Rotation value
should be adjusted to make sure application that receive already
"corrected" images do not get confused by Rotation still reporting
a value.

Howerver, as an image sensor can only compensate rotations by applying
H/V flips, only correct Rotation when the mounting rotation is 180
degrees.

5a142438b0 gstreamer: Add enable_auto_focus option to the GStreamer plugin
Cameras such as the PiCam 3 support auto-focus, but the GStreamer plugin
for libcamera does not enable auto-focus. With this patch auto-focus can
be enabled for cameras that support it. By default it is disabled, which
means default behaviour remains unchanged. For cameras that do not
support auto-focus, an error message shows up if auto-focus is enabled.

This was tested on cameras that do not support auto-focus (e.g. PiCam2)
and was tested on a camera that does support auto-focus (PiCam3). The
test involved setting the focus to AfModeContinous and observing it.
However, by not setting "auto-focus-mode" or using AfModeManual as
the "auto-focus-mode" both resulting in auto-focus being disabled.

b9113a8626 libcamera: pipeline: Register device numbers with camera
Register the identified device numbers with each camera as the
SystemDevices property.

This facilitates camera daemons or other systems to identify which
devices are being managed by libcamera, and can prevent duplication of
camera resources.

As the SystemDevices property now provides this list of devices, use it
directly from within the CameraManager when adding a Camera rather than
passing it through the internal API.

The CameraManager exposes addCamera and removeCamera as public API
calls, while they should never be called from an application. These
calls are only expected to be used by PipelineHandlers to update the
CameraManager that a new Camera has been created and allow the Camera
Manager to expose it to applications.

Remove the public calls and update the private implementations such that
they can be used directly by the PipelineHandler through the internal
CameraManager::Private provided by the Extensible class.

e58121cfc1 libcamera: rkisp1: Fix enumeration of RAW formats
The current implementation enumerates a single RAW format (the sensor's
resolution) and does that regardless of what role the
CameraConfiguration has been generated for.

Fix this by:
- Enumerate RAW StreamFormats only when the requested role is
  StreamRole::Raw
- Add all the sensor's provided resolutions that fit the video device
  output maximum size

Before this patch, a single RAW size was enumerated in stream formats

 * Pixelformat: SRGGB10 (4208x3120)-(4208x3120)/(+1,+1)
  - 4208x3120

With this patch applied all sensor's supported resolutions are
enumerated but only when the stream role RAW is explicitly requested

 * Pixelformat: SRGGB10 (1048x780)-(4208x3120)/(+0,+0)
  - 1048x780
  - 2104x1560
  - 4032x3024
  - 4208x3120
