ABI Compliance:
abi-compliance-checker reports 99% binary compatibility and 81.4% source
compatibilty between version 0.0.5 and 0.1.
- Binary compatibility: 99%
- Source compatibility: 81.4%
- Total binary compatibility problems: 4, warnings: 2
- Total source compatibility problems: 165, warnings: 7
Now that we have funtional ABI validation, the soname has been updated from
libcamera.so.0.0.5 to libcamera.so.0.1.
Future releases will now maintain the same soname until an ABI breakage is
detected to reduce the repackaging and rebuilding of other components that may
use libcamera. The abi-compatibility report can now be generated with the new
utility './utils/abi-compat.sh'.
Key differences here are due to preventing the installation of internal and
private headers in the packaging process, and most of this API compatibility
should not be visible to applications with the exception of:
- Camera::generateConfiguration ( StreamRoles const& roles )
The StreamRoles type definition has been removed. This is now handled as a
Span<StreamRole> to prevent unnecessary allocations and copies.
- CameraManager::addCamera ( std::shared_ptr<struct Camera> camera, std::vector<unsigned long>const& devnums )
- CameraManager::get ( dev_t devnum )
- CameraManager::removeCamera ( std::shared_ptr<struct Camera> camera )
These functions of the CameraManager were for use exclusively by the V4L2
adaptation layer, and not intended for use by applications. This has now been
reworked to use the new SystemDevices and the redundant functions removed.
The ABI/API breakages have been introduced by:
5ca0c9276f28 ("libcamera: CameraManager: Remove ::get(dev_t)")

The provider g_autoptr variable introduced by commit adb1bbb748a1
("tests: gstreamer: Test cameras' enumeration from GstDeviceProvider")
is left uninitialized when declared. The cleanup function could thus get
called on an unitialized variable if the scope was exited before the
variable gets initialized. This can't occur here, but gcc 8.4.0 still
complains about it:
/usr/include/glib-2.0/glib/gmacros.h: In member function ‘virtual int GstreamerDeviceProviderTest::run()’:
/usr/include/glib-2.0/glib/gmacros.h:1049:27: error: ‘provider’ may be used uninitialized in this function [-Werror=maybe-uninitialized]

^
../test/gstreamer/gstreamer_device_provider_test.cpp:37:32: note: ‘provider’ was declared here
g_autoptr(GstDeviceProvider) provider;
Silence the error by initializing the variable to NULL at declaration
time. This is a good practice in any case, as later refactoring could
otherwise introduce a scope exit before initialization.

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.

The imx708 must drop a single frame on startup - but only when in HDR
mode. Non-HDR modes do not need to drop frames. Fix the logic in
hideFramesModeSwitch() which currently unconditionally advertises to
drop one frame.
Unfortunately there is no clear way to tell if the sensor is in the HDR
mode. So for now, look the resolution and framerate to deduce this.
Additionally ensure we override hideFramesStartup() and return the same
number as hideFramesModeSwitch().

New TI SoCs from J7 and AM62 family have a camera pipeline that receives
data using Cadence's DPHY-RX and CSI-RX bridge. A pixel-grabbing "shim"
IP routes this incoming stream of data to the DMA subsystem, to finally
store the frame data in memory.
The driver for this is not merged in mainline yet, but v7 was posted [1]
on linux-media list a few months ago.
With some minor fixes, the work-in-progress v8 series [2] works with the
simple pipeline handler, so we enable support for this device.

libcamera uses udev to support hotplug (and unplug) detection. This is
an optional feature, which gets selected automatically if udev is
available. Users may however want to build libcamera without hotplug
detection, even if udev is available on the system. Add a new feature
option to control udev support. The default value is auto, which retains
the existing behaviour.

When packaging libcamera, distributions may break IPA module signatures
if the packaging process strips binaries. This can be fixed by resigning
the modules, but the process is error-prone.
Add a command line ipa-verify utility that tests the signature on an IPA
module to help packagers. The tool takes a single argument, the path to
an IPA module shared object, and expects the signature file (.sign) to
be in the same directory.
In order to access the public key needed for signature verification, add
a static function to the IPAManager class. As the class is internal to
libcamera, this doesn't affect the public API.

Recent media-ctl versions include the framerate in the fmt property output:

type V4L2 subdev subtype Sensor flags 0
device node name /dev/v4l-subdev6

crop.bounds:(16,6)/2592x1944
crop:(16,6)/2592x1944]
-> "ipu3-csi2 1":0 [ENABLED]
This resulted in $sensor_size getting set to: "2592x1944@1 30", which
causes the script to fail.
Fix this by:
1. Replacing the gsub() to remove the '/' between e.g. SBGGR10_1X10
and 2592x1944 with a sub() so that only that first '/' gets replaced
(resulting in a $sensor_size of "2592x1944@1/30" instead).
2. Adding a new sub() to remove the @1/30 suffix.

Change the parameter type of `generateConfiguration()` from `const std::vector&`
to `libcamera::Span`. A span is almost always preferable to a const vector ref
because it does not force dynamic allocation when none are needed, and it allows
any contiguous container to be used.
A new overload is added that accepts an initializer list so that
cam->generateConfiguration({ ... })
keeps working.
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.

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.

If a metering/exposure/constraint mode is not listed in the sensor
tuning file, and a control for the missing mode is set on the agc, we
terminate the application with a fatal log message.
Instead of this fatal termination, log a warning message and switch to
the appropriate default mode so that the application continues running.

Some sensor tuning files were missing the short and/or long exposure
mode profiles. Add the missing items to the relevant files.
As a drive-by, rename the "sport" exposure profile to "short" for the
IMX290 tuning.

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

Currently each RkISP1 path (main and self) generate a configuration
by bounding the sensor's resolution to their respective maximum output
aspect ratio and size.
Size maxResolution = maxResolution_.boundedToAspectRatio(resolution)
.boundedTo(resolution);
In the case of self path, whose maximum size is 1920x1920, the generated
configuration could get assigned unusual sizes, as the result of the
above operation.
As an example, with the imx258 sensor whose resolution is 4208x3118, the
resulting size for the Viewfinder use case is an unusual 1920x1423.
Fix this by assigning to each role a desired output size:
- Use the sensor's resolution for StillCapture and Raw
- Use 1080p for Viewfinder and VideoRecording

Crop on the resizer sink pad before downscaling to the aspect ratio
of the desired output size.
Cropping the input frame to the output aspect ratio allows to maintain
the correct picture proportions, as otherwise downscaling would change
the image geometry.

The generateConfiguration() implementation in the Rockchip RkISP1
pipeline handler uses by default the self path (if available) for
the Viewfinder and VideoRecording StreamRoles.
The validate() implementation, at the contrary, prefers using the main
path, when available, for all streams.
As the self-path is limited in output resolution to 1920x1920,
generating a configuration using the self path limits the maximum
stream size to 1920x1920, while higher resolutions can be obtained by
using the main path.
Align the generateConfiguration() implementation to the validate() one
by using the main path by default if available.

Update the AfMode control description to explicitly define a

On startup, the camera will move the lens to the position given by the
default value of the LensPosition control if operating in manual focus
mode. Typically this would be the hyperfocal position of the lens.

Commit a3178dd0391f ("ipa: rkisp1: agc: drop hard-coded analogue gain range")
removed both minimum and maximum limits for the analogue gain value.
However, as some sensors can potentially have a minimum gain lower than
1.0, restore the check for the minimum limit.
