2021-05-24ipa: Move core IPA interface documentation to a .cpp fileUmang Jain
Moving the core.mojom documentation to its corresponding .cpp file (core_ipa_interface.cpp). This will allow Doxygen to generate the documentation for IPABuffer, IPASettings and IPAStream structures. Since the .mojom files are placed in include/ directory, the .cpp file will live in $sourcedir/src/libcamera/ipa/ - which can also contain documentation for other mojom generated IPA interfaces in subsequent commit. Also hide the constructors in generated IPA interface from doxygen, via #ifndef __DOXYGEN__. These constructors provide no major value in documenting them, instead will spew out doxygen warnings during the build.

2021-05-24libcamera: V4L2Control: remove V4L2Control classesHirokazu Honda
V4L2ControlId and V4L2ControlInfo are just convenience classes to create ControlId and ControlInfo from v4l2_query_ext_control. Therefore, there is no need of being a class. It is used only from V4L2Device. This removes the classes and put the equivalent functions of creating ControlId and ControlInfo in v4l2_device.cpp. Signed-off-by: Hirokazu Honda <hiroh@chromium.org> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-05-18libcamera: utils: Add enumerate view for range-based for loopsLaurent Pinchart
Range-based for loops are handy and widely preferred in C++, but are limited in their ability to replace for loops that require access to a loop counter. The enumerate() function solves this problem by wrapping the iterable in an adapter that, when used as a range-expression, will provide iterators whose value_type is a pair of index and value reference. The iterable must support std::begin() and std::end(). This includes all containers provided by the standard C++ library, as well as C-style arrays. A typical usage pattern would use structured binding to store the index and value in two separate variables: std::vector<int> values = ...; for (auto [index, value] : utils::enumerate(values)) { ... } Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>

In most cases, file paths in meson files start with get_option(). To maintain a consistent theme, use meson's get_option('includedir') universal option over raw 'include'.

2021-05-11libcamera: camera_sensor: Fix frame lengths calculated by sensorInfo()David Plowman
The minimum and maximum vblanking can change when a new format is applied to the sensor subdevice, so be sure to retrieve up-to-date values. The V4L2Device acquires the new updateControlInfo() method to perform this function, and which the CameraSensor calls automatically if its setFormat method is used to update the sensor. However, not all pipeline handlers invoke the setFormat method directly, so the new method must be made publicly available for pipeline handlers to call if they need to.

Asynchronous tasks can only be submitted while the IPA is running. Further more, the shutdown sequence can not be tracked with a simple running flag. We can also be in the state 'Stopping' where we have not yet completed all events, but we must not commence anything new. Refactor the running_ boolean into a stateful enum to track this.

On DelayedControls::reset(), the values retrieved from the sensor device were added to the queues with the updated flag set to true. This would cause the helper to write out the value to the device again on the first DelayedControls::applyControls() call. This is unnecessary, as the controls written are identical to what is stored in the device driver. Fix this by explicitly setting the update flag to false in DelayedControls::reset() when adding the controls to the queue. Additionally, use the Info() constructor when adding items to the queue for consistency.

2021-03-12libcamera: delayed_controls: Add notion of priority writeNaushir Patuck
If an exposure time change adjusts the vblanking limits, and we set both VBLANK and EXPOSURE controls through the VIDIOC_S_EXT_CTRLS ioctl, the latter may fail if the value is outside of the limits calculated by the old VBLANK value. This is a limitation in V4L2 and cannot be fixed by setting VBLANK before EXPOSURE in a single VIDIOC_S_EXT_CTRLS ioctl. The workaround here is to have the DelayedControls object mark the VBLANK control as "priority write", which then write VBLANK separately from (and ahead of) any other controls. This way, the sensor driver will update the EXPOSURE control with new limits before the new values is presented, and will thus be seen as valid. To support this, a new struct DelayedControls::ControlParams is used in the constructor to provide the control delay value as well as the priority write flag.

Since commit 96aecfe36508 ("libcamera: camera_sensor: Use active area size as resolution") the CameraSensor::resolution() method returned the sensor's active pixel area size. As the CameraSensor::resolution() method is widely used in the library code base to retrieve the maximum frame size the sensor can produce, in case it is smaller than the pixel area size the returned size cannot be used to configure the sensor correctly. Fix this by returning the maximum frame resolution the sensor can produce, or the pixel area size in case the sensor embeds and ISP that can upscale and the supported maximum frame size is thus larger that the pixel array size.

2021-03-04pipeline: ipa: raspberrypi: Pass exposure/gain values to IPA though controlsNaushir Patuck
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.

Update Linux headers to v5.12-rc1, to provide the MEDIA_ENT_F_PROC_VIDEO_ISP entity function. The DRM FourCC and modifiers that were manually added in commits 9db0ed5e2065, 38f2efb05cef and 90c793c6989f are kept. New Intel DRM format modifiers are conflicting with IPU3_FORMAT_MOD_PACKED, which is updated as a result. The V4L2 controls and formats that were manually added in commit 43d81d43fe91 are kept. This causes a conflict in the V4L2 control base for V4L2_CID_USER_BCM2835_ISP_BASE that needs to be resolved in the downstream Raspberry Pi kernel first. The intel-ipu3.h header is manually exported with the scripts/headers_install.sh script. The script complained about a missing "WITH Linux-syscall-note" license extension, which has been worked around manually. The issue has been reported upstream in [1].
