2021-08-31libcamera: pipeline: simple: Delay opening of video device until init()Laurent Pinchart
The video device is currently opened in the SimpleCameraData constructor. This requires opening the video devices on-demand the first time they're accessed, which gets in the way of refactoring of per-entity data storage in the pipeline handler. Move opening of the video device to the SimpleCameraData::init() function. The on-demand open mechanism isn't touched yet, it will be refactored later.

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. ($) cam -c1 -swidth=640,height=480,role=raw - CIO2 configuration: 4208x3118-SGRBG10_IPU3 [*] In order to address this constraint, only compare the ratio with single precision to make a better decision on the sensor resolution policy selection.

2021-08-31ipu3: cio2: Change sensor size selection policyUmang Jain
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.

This prepares a base to introduce custom selection of sensor format based on platform(Soraka or Nautilus) constraints. The changes in selection policy will be introduced in a subsequent patch. The function is copied from CameraSensor::getFormat() in the IPU3 pipeline handler code to be later changed on top. The copy is not verbatim and has a minor change as follows: CameraSensor::getFormats() has access to a V4L2Subdevice::Formats internally and use it directly to iterate over supported camera sensor frame sizes.

2021-08-31libcamera: camera_sensor: Transform CameraSensor::sizes()Umang Jain
In CameraSensor, the mbusCodes() and sizes() accessor functions retrieves all the supported media bus codes and the supported sizes respectively. However, this is quite limiting since the caller probably isn't in a position to match which range of sizes are supported for a particular mbusCode. Hence, the caller is most likely interested to know about the sizes supported for a particular media bus code. This patch transforms the existing CameraSensor::sizes() to CameraSensor::sizes(mbuscode) to achieve that goal. The patch also transforms existing CIO2Device::sizes() in IPU3 pipeline handler to CIO2Device::sizes(PixelFormat) on a similar principle. The function is then plumbed to CameraSensor::sizes(mbusCode) to enumerate the per-format sizes as required in PipelineHandlerIPU3::generateConfiguration().

2021-08-19ipa: Use FileDescriptor instead of int in layers above IPC payloadPaul Elder
Regarding (de)serialization in isolated IPA calls, we have four layers: - struct - byte vector + fd vector - IPCMessage - IPC payload The proxy handles the upper three layers (with help from the IPADataSerializer), and passes an IPCMessage to the IPC mechanism (implemented as an IPCPipe), which sends an IPC payload to its worker counterpart. When a FileDescriptor is involved, previously it was only a FileDescriptor in the first layer; in the lower three it was an int. To reduce the risk of potential fd leaks in the future, keep the FileDescriptor as-is throughout the upper three layers. Only the IPC mechanism will deal with ints, if it so wishes, when it does the actual IPC. IPCPipeUnixSocket does deal with ints for sending fds, so the conversion between IPCMessage and IPCUnixSocket::Payload converts between FileDescriptor and int. Additionally, change the data portion of the serialized form of FileDescriptor to a 32-bit unsigned integer, for alightnment purposes and in preparation for conversion to an index into the fd array. Also update the deserializer of FrameBuffer::Plane accordingly.

The bcm2835-isp.h is included with quotes rather than angle brackets. Quoted includes is reserved for internal includes, while the linux/bcm2835-isp.h header is exported from the Linux kernel. Fix the inclusion type.

2021-08-17pipeline: ipu3: Skip recording timestamp for cancelled buffersUmang Jain
There is no point in recording sensor's timestamp when V4L2VideoDevice has marked the frame buffers with FrameMetadata::FrameCancelled (happens when the streams are stopped). The metadata is mostly invalid for cancelled buffers hence, setting timestamp on invalid metadata does not make sense (however some metadata can be considered valid for e.g. returning cause of failure through metadata on cancelled buffers).

Replace manual static casts from the PipelineHandler pointer to a derived class pointer with helper functions in the camera data classes. This simplifies code accessing the pipeline from the camera data.

The PipelineHandler controls() and properties() functions are only used by the Camera class. Now that the controls and properties are stored in the Camera::Private class, we can drop those functions and access the private data directly in Camera::controls() and Camera::properties().
