2021-09-07libcamera: v4l2_videodevice: Drop toV4L2PixelFormat()Laurent Pinchart
The V4L2VideoDevice::toV4L2PixelFormat() function is incorrectly implemented, as it will pick a multi-planar format if the device supports the multi-planar API, even if only single-planar formats are supported. This currently works because the implementation calls V4L2PixelFormat::fromPixelFormat(), which ignores the multiplanar argument and always returns a single-planar format. Fixing this isn't trivial. As we don't need to support multi-planar V4L2 formats at this point, drop the function instead of pretending everything is fine, and call V4L2PixelFormat::fromPixelFormat() directly from pipeline handlers. As the single-planar case is the most common, set the multiplanar argument to false by default to avoid long lines.

2021-09-02libcamera: Drop emitter object pointer from signal argumentsLaurent Pinchart
Many signals used in internal and public APIs carry the emitter pointer as a signal argument. This was done to allow slots connected to multiple signal instances to differentiate between emitters. While starting from a good intention of facilitating the implementation of slots, it turned out to be a bad API design as the signal isn't meant to know what it will be connected to, and thus shouldn't carry parameters that are solely meant to support a use case specific to the connected slot. These pointers turn out to be unused in all slots but one. In the only case where it is needed, it can be obtained by wrapping the slot in a lambda function when connecting the signal. Do so, and drop the emitter pointer from all signals. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Umang Jain <umang.jain@ideasonboard.com>

2021-09-02libcamera: base: signal: Support connecting signals to functorsLaurent Pinchart
It can be useful to connect a signal to a functor, and in particular a lambda function, while still operating in the context of a receiver object (to support both object-based disconnection and queued connections to Object instances). Add a BoundMethodFunctor class to bind a functor, and a corresponding Signal::connect() function. There is no corresponding disconnect() function, as a lambda passed to connect() can't be later passed to disconnect(). Disconnection typically uses disconnect(T *object), which will cover the vast majority of use cases.

2021-09-02libcamera: base: bound_method: Remove BoundMethodArgs specializationLaurent Pinchart
The BoundMethodArgs specialization for the void return type is only needed to avoid accessing the ret_ member variable that is lacking from the corresponding BoundMethodPack specialization. As the member variable is only accessed in the invokePack() function, instead of specializing the whole class we can use SFINAE to select between two different implementations of the function. SFINAE can only depend on the function template parameters, not the parameters of the class template in which the function is defined: "Only the failures in the types and expressions in the immediate context of the function type or its template parameter types are SFINAE errors." We thus can't use the type R in an std::enable_if expression for the invokePack() function. To work around this, we have to add a type T to the function template definition, which defaults to R, and use T with std::enable_if.

2021-09-02libcamera: Use simpler Signal::disconnect() functionLaurent Pinchart
When disconnecting a signal from a receiver, it is usually not necessary to specify the receiver's slot function explicitly, as the signal is often connected to a single slot for a given receiver. We can thus use a simpler version of Signal::disconnect() that takes a pointer to the receiver object only. This reduces code size, as the disconnect() function is a template function.

2021-09-01test: v4l2_compat: Disable test when ASan is enabledLaurent Pinchart
The V4L2 compat test runs v4l2-ctl and v4l2-compliance with v4l2-compat.so preloaded. If libcamera is compiled with the address sanitizer enabled, the ASan library will be loaded due to preloading v4l2-compat.so. This however doesn't occur early enough in the dynamic linking process due to the v4l2 executables not being themselves linked to the ASan runtime, which causes ASan to abort with ==2198==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD. Using LD_PRELOAD to load the ASan runtime would fix this issue, but it requires knowing the absolute path to the ASan shared object. This is compiler-dependent and for clang, architecture-dependent as well. Until we figure out how to safely retrieve that information, disable the test when ASan is enabled as a quick fix.

2021-09-01libcamera: base: log: Don't crash when logging after Logger destructionLaurent Pinchart
libcamera isn't supposed to log messages after the logger is destroyed, as the global logger instance is destroyed after the main() function returns, and the camera manager is supposed to have been stopped and destroyed before that. This rule is difficult to enforce in the V4L2 compat implementation, as there is no location where we can destroy the camera manager manually before the logger is destroyed. This results in a use-after-free condition when the camera manager gets stopped during destruction. Fix it by not trying to print log messages when the global logger instance has been destroyed. This is a bit of a hack, but hopefully not too bad. There could be race conditions when using a CameraManager instance that is destroyed as part of the destruction of global variables (like the V4L2 compat layer does, it wraps CameraManager in a singleton V4L2CompatManager class, and destroys it when V4L2CompatManager is destroyed) as the CameraManager thread will still be running when the logger gets destroyed, but this doesn't cause any regression as we destroy the logger without any safeguard measure today anyway. There are other options that could be considered. Forcing destruction of the logger after the camera manager in the V4L2 compat layer is one of them, but turned out to be difficult. For instance care would need to be taken *not* to log any message in the mmap() wrapper if the fd doesn't match a wrapped camera, as mmap() is called very early in the initialization process, before libcamera and the logger get initialized. The resulting implementation would likely be fairly complex. Another option could be to wrap the logger with a shared pointer, and keep a reference to it in CameraManager. That's more intrusive, and it's not clear if it would be worth it. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com>

2021-08-31ipu3: cio2: Tweak sensor size selection policyUmang Jain
Do not compare higher precision of the ratios, as it might lead to absurd selection of sensor size for a relatively low requested resolution size. For example: The imx258 driver supports the following sensor resolutions: - 4208x3118 = 1.349583066 - 2104x1560 = 1.348717949 - 1048x780 = 1.343589744 It can be inferred that, that the aspect ratio only differs by a small mantissa with each other. It does not makes sense to select a 4208x3118 for a requested size of say 640x480 or 1280x720, which is what is happening currently.

The current implementation of getSensorFormat() prioritizes sensor sizes that match the output size FOV ratio. Modify the frame size selection procedure to prioritize resolutions with the same FOV as the sensor's native one, to avoid cropping in the sensor pixel array. For example: - on a Soraka device equipped with ov13858 as back sensor, with a native resolution of 4224x3136 (4:3), when requested to select the sensor output size to produce 1080p (16:9) a frame size of 2112x1188 (16:9) is selected causing the ImgU configuration procedure to fail. If a resolution with the same FOV as the sensor's native size, such as 2112x1568 (4:3), is selected the pipeline works correctly.

The patch also transforms existing CIO2Device::sizes() in IPU3 pipeline handler to CIO2Device::sizes(PixelFormat) on a similar principle.

2021-08-27Documentation: Explicitly enable DotKieran Bingham
The dot package is identified as a required package for the Documentation, and already marked as a required dependency with meson. If meson can not find 'dot', then the documentation will not be built, so we can explicitly enable it in our Doxyfile.

2021-08-27base: class: Remove undesired semi-colon from LIBCAMERA_O_PTRKieran Bingham
The LIBCAMERA_O_PTR() define adds the ';' at the end of the templated call to _o(). While this works for the only current user in camera_manager.cpp, even the statement there adds another semi-colon following it. The addition of the semi-colon in the define unnecessarily prohibits the macro from being used in places other than the end of a statement. Remove it.
