2021-03-12libcamera: delayed_controls: Fix off-by-one error in get()Naushir Patuck
There was an off-by-one error in DelayedControls::get() when picking controls from the queue to return back to the pipeline handler. This is only noticeable as small oscillations in brightness when closely viewing frame while AGC is running. The old StaggeredCtrl did not show this error as the startup queuing mechanism has changed in DelayedControls. Fix this by indexing to the correct position in the queue.

2021-03-12libcamera: delayed_controls: Remove spurious no-op queued controlsNaushir Patuck
In DelayedControls::applyControls(), the controls queue would be extended via a no-op control push to fill the intermittent slots with unchanged control values. This is needed so that we read back unchanged control values correctly on every frame. However, there was one additional no-op performed on every frame that is not required, meaning that any controls queued by the pipeline handler would have their write delayed by one further frame. The original StaggeredCtrl did not do this, as it only had one index to manage, whereas DelayedControls uses two. Remove this last no-op push so that the pipeline_handler provided controls would be written on the very next frame if possible. As a consequence, we must mark the control update as completed within the DelayedControls::applyControls() loop, otherwise it might get reused when cycling through the ring buffer.

2021-03-12libcamera: delayed_controls: Remove unneeded write when starting upNaushir Patuck
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.

2021-03-04libcamera: pipeline: simple: Support camera sensors that contain an ISPLaurent Pinchart
Camera sensors can include an ISP. For instance, the AP1302 external ISP can be connected to up to two raw camera sensors, and the combination of the sensors and ISP is considered as a (smart) camera sensor from libcamera's point of view. The CameraSensor class has limited support for this already. Extend the simple pipeline handler to support such sensors, by using the media entity corresponding to the ISP instead of the raw camera sensor's entity. We don't need to handle the case where an entity in the SoC would expose the MEDIA_ENT_F_PROC_VIDEO_ISP function, as pipeline containing an ISP would have a dedicated pipeline handler. The implementation is limited as it won't support other multi-entity camera sensors (such as CCS). While this would be worth supporting, we don't have a test platform with a CCS-compatible sensor at this point, so let's not over-engineer the solution. Extending support to CCS (and possibly other sensor topologies) will likely involve helpers that can be used by other pipeline handlers (such as generic graph walk helpers for instance) and extensions to the CameraSensor class.

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.

This makes the configure() function signature cleaner, and will allow passing additional parameters (such as stride and buffer count).

2021-03-03libcamera: pipeline: simple: converter: Group query functions togetherLaurent Pinchart
The SimpleConverter class has different sets of functions, related to static queries, device configuration and runtime operation. Group the query functions together. While at it, swap the arguments to the strideAndFrameSize() function to match the order in which pixel format and size are usually specified. No functional change is included.

2021-03-03libcamera: pipeline: simple: Don't override stride at configure timeLaurent Pinchart
The stride (and frame size) calculation has been moved from configure time to configuration validate time by commit 89fb1efac240 ("libcamera: simple: Fill stride and frameSize at config validation"). This change has however left one stray setting of the stride when configuring the converter. Fix it. While at it, turn the SimpleConverter::configure() output configuration argument to a const reference to emphasize it can't be null and isn't modified by the function, and rename it from cfg to outputCfg to make its purpose clearer.

2021-02-25libcamera: ipu3: Initialize V|H flip supportJacopo Mondi
The flag that is used to record if the sensor driver supports the H/V flip controls is initialized at camera creation time, but it was not initialized by the IPU3Camera constructor, resulting in erroneous values that might break capture for sensor that do not support flipping. Fix this by initializing the flag in the class constructor.

2021-02-23libcamera: Enable vimc pipeline handler when tests are enabledLaurent Pinchart
The addition of the new IPA IPC mechanism compiles pipeline-specific headers to define the interface between the pipeline and the IPA. This was optimised in 08ce394465b5 ("meson: ipa, proxy: Only build proxies for enabled pipelines") to only build for enabled pipelines, however the tests directly use the VIMC pipeline handler, and require it to be built. Create a local variable to store the requested pipelines from the user configuration and extend the enabled pipelines to ensure that VIMC is always enabled if the tests are also enabled Fixes: 08ce394465b5 ("meson: ipa, proxy: Only build proxies for enabled pipelines") Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Tested-by: Sebastian Fricke<sebastian.fricke@posteo.net>
