The IPAIPU3 interface currently uses event-type based structures in order to communicate with the pipeline-handler (and vice-versa). Replace the event based structures with dedicated functions associated to each operation. The translated naming scheme of actions to signals are: ActionSetSensorControls => setSensorControls ActionParamFilled => paramsBufferReady ActionMetadataReady => metadataReady The translated naming scheme of events to dedicated functions are: EventProcessControls => queueRequest() EventStatReady => processStatsBuffer() EventFillParams => fillParamsBuffer() The dedicated functions are called from pipeline-handler to the IPA using IPC. These functions run asynchronously and when completed, the IPA emits the respective signals as stated above in the translated naming scheme. The EventProcessControls is translated to queueRequest() to bring symmetry to the IPU3 interface with other IPA interfaces.

Under the right circumstances, the alsc calculations could spread the colour errors across the entire image as lambda remains unbound. This would cause the corrected image chroma values to slowly drift to incorrect values. This change adds a config parameter (alsc.lambda_bound) that provides an upper and lower bound to the lambda value at every stage of the calculation.

2022-04-01libipa: camera_sensor_helper: Implement exponential gain modelLaurent Pinchart
The CameraSensorHelper specifies two gain models, linear and exponential. They are modelled after the MIPI CCS specification. Only the linear model has been implemented, the exponential model was left for later. We now need to support sensors that configure their gain in a hardware register with a value expressed in dB. This has similarities with the MIPI CCS exponential gain model, but is only has an exponential factor, while CCS also allows sensors to support a configurable linear factor. The full CCS exponential model needs two values (for the linear and exponential factors) to express a gain, while IPAs use a single linear gain value internally. However, the exponential gain model example in the CCS specification has a fixed linear factor, which may indicate that it could be common for sensors that implement the exponential gain model to only use the exponential factor. For this reason, implement the exponential gain model with a fixed linear factor, but with a sensor-specific coefficient for the exponential factor that allows expressing the gain in dB (or other logarithmical units) instead of limiting it to powers of 2 as in the MIPI CCS specification.

2022-03-23libcamera: v4l2_videodevice: Clarify setting of v4l2_buffer timestampUmang Jain
Add a comment to clarify why we set v4l2_buffer timestamp while queuing the buffer (VIDIOC_QBUF). The timstamps are required to be supplied for memory-to-memory devices for output streams which then are copied to capture stream buffers with the help of V4L2_BUF_FLAG_TIMESTAMP_COPY (set by the driver).

2022-03-23libcamera: v4l2_videodevice: Remove setting of buffer sequenceUmang Jain
The struct v4l2_buffer documentation [1] clearly states that setting of the sequence is done by the driver. libcamera does not really need to set this field while queuing the buffer(s).

2022-03-23libcamera: camera_sensor: Add OV5640 sensor propertiesPaul Elder
Add an entry to the sensor properties for the ov5640. Only the first test pattern is included as the others that are exposed by the kernel don't correspond to any that are defined in the libcamera control.
