2022-12-09[HACK] camera_sensor: Do not prefer modes with the same ratioJacopo Mondi
The CameraSensor::getFormat() function prefers modes with the same FOV ratio of the requested image size. This has for some sensors, like imx258, the undesirable effect of mapping low-res modes (320x240) to the largest sensor mode (4032x3024) compromising the frame rate. This impacts the Android HAL layer, which requires low-res modes to be 30FPS capable. Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>

The HAL config file is assumed to be in the LIBCAMERA_SYSCONF_DIR directory, which is defined by the meson build system at compile time.

Currently, libcamera does not have information for the ov8858 sensor used in the PinePhone Pro, a phone designed to run Linux. This commit adds metadata, especially that sensor gain is reported and set in 1/16 discrete increments.

2022-12-09libcamera: camera_sensor: Apply flips at setFormat()Jacopo Mondi
Augment the CameraSensor::setFormat() function to configure horizontal and vertical flips before appllying the image format on the sensor. Applying flips before format is crucial as they might change the Bayer pattern ordering. To allow users of the CameraSensor class to easily pass the requested Transform add to the V4L2SubdeviceFormat class a 'transform' member, by default initialized to Transform::Identity. Moving the handling of H/V flips to the CameraSensor class allows to remove quite some boilerplate code from the IPU3 and RaspberryPi pipeline handlers. Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>
2022-12-09libcamera: camera_sensor: Validate TransformJacopo Mondi
The two pipeline handlers that currently support Transform do so by operating H/V flips on the image sensor, instead of rotating on the ISP. As the image sensor performs the actual rotation, centralize the code that validates a requested Transform against the camera sensor rotation and capabilities in the CameraSensor class. The implementation in the IPU3 pipeline handler was copied from the RaspberryPi implementation, and is now centralized in CameraSensor to make it easier for other platforms that do not rotate on the ISP to implement support for Transform using the CameraSensor class.

2022-12-09libcamera: bayer_format: Expand documentationJacopo Mondi
The current documentation of the BayerFormat::transform() function reports examples on the Bayer components ordering transformation for horizontal flip (mirroring) but not for vertical flip or for the combination of the two. It might be useful to complete the documentation to eases understanding of the transform() function on a sensor's Bayer pattern. Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>
2022-12-09libcamera: camera_sensor: Do not clear camera flips when listing formatsDavid Plowman
Previously the code used to clear the camnera's h and v flip bits when enumerating the supported formats so as to obtain any Bayer formats in the sensor's native (untransformed) orientation. However this fails when the camera is already in use elsewhere. Instead, we query the current state of the flip bits and transform the formats - which we obtain in their flipped orientation - back into their native orientation to be stored.

2022-11-29ipa: raspberrypi: agc: Fix digital gain calculation for manual modeNaushir Patuck
The digital gain calculation uses a total exposure value computed with the current AGC state. However, this is wrong in the case of manual shutter/gain controls, as the total exposure value used must be the value computed when the AGC sent the manual shutter/gain controls to the pipeline handler to action. To fix this, the IPA now adds the historical AgcStatus structure to the metadata (tagged with "agc.delayed_status"). This historical AgcStatus structure contains the total exposure value calculated when the AGC sent the manual shutter/gain controls to the pipeline handler.

2022-11-29ipa: raspberrypi: Use an array of RPiController::Metadata objectsNaushir Patuck
Allow the IPA to cycle through an array of RPiController::Metadata objects, one per prepare()/process() invocation, when running the controller algorithms. This allows historical metadata objects to be retained, and subsequently passed into the controller algorithms on future frames. At present, only a single index into this array is used. This change provides a route to fixing a problem with the AGC algorithm, where if a manual shutter/gain is requested, the algorithm does not currently retain any context of the total exposure that it has calculated. As a result, the wrong digital gain would be applied when the frame with the manual shutter/gain is processed by the ISP.

2022-11-28libcamera: v4l2_device: Workaround faulty control menusKieran Bingham
Some UVC cameras have been identified that can provide V4L2 menu controls without any menu items. This leads to a segfault where we try to construct a ControlInfo(Span<>,default) with an empty span. Convert the v4l2ControlInfo and v4l2MenuControlInfo helper functions to return std::optional<ControlInfo> to be able to account in the caller if the control is valid, and only add acceptable controls to the supported control list. Menu controls without a list of menu items are no longer added as a valid control and a warning is logged. This also fixes a potential crash that would have occured in the unlikely event that a ctrl.minimum was set to less than 0.

2022-11-25pipeline: rkisp1: Support raw Bayer capture at runtimeFlorian Sylvestre
Implement support for raw Bayer capture at runtime, from start() to stop(). Support of raw formats in the camera configuration is split to a subsequent change to ease review. In raw mode, the ISP is bypassed. There is no need to provide parameter buffers, and the ISP will not generate statistics. This requires multiple changes in the buffer handling: - The params and stats buffers don't need to be allocated, and the corresponding video nodes don't need to be started or stopped. - The IPA module fillParamsBuffer() operation must not be called in queueRequestDevice(). As a result, the IPA module thus doesn't emit the paramsBufferReady signal. The main and self path video buffers must thus be queued directly in queueRequestDevice(). - The tryCompleteRequest() function must not to wait until the params buffer has been dequeued. - When the frame buffer has been captured, the IPA module processStatsBuffer() operation must be called directly to fill request metadata.

2022-11-25ipa: rkisp1: Support raw capture in IPA operationsLaurent Pinchart
The RkISP1 can capture raw frames by bypassing the ISP. In that mode, the ISP will not produce statistics nor consume parameters. Most algorithms will thus be unable to run, with one exception: the AGC will still be able to configure the sensor exposure time and analog gain in manual mode. To prepare for this, add the ability to disable algorithms for the duration of the capture session based on the camera configuration. Individual algorithms report whether they support raw formats at construction time, and the IPA module disables algorithms in configure() based on the stream configurations. Disabled algorithms are skipped during the capture session in the processStatsBuffer() operation. As the ISP doesn't produce statistics, don't try to access the stats buffer. There is no need for similar logic in fillParamsBuffer() as that operation won't be called for raw capture. All algorithms report not supporting raw capture by default. Raw support in AGC will be added separately. The feature is implemented in the RkISP1 module without any support from libipa at this point to avoid designing a generic API based on a single user. This may be changed in the future.
