2022-10-04pipeline: raspberrypi: Detect monochrome "R" formats as being rawDavid Plowman
The "R" pixel formats (R8, R10, R10_CSI2P etc.) record the associated colour space as being YUV rather than RAW, meaning that the code was not detecting them as being raw formats. In the case of Raspberry Pi, we deal only with raw formats, so the revised test must work correctly for both these and the standard Bayer formats.

The base V4L2Device class is bound to a video device node by either open(), which opens the device node and creates a new file descriptor, or setFd(), which takes an already open file descriptor. The former populates the V4L2Device instance controls, while the latter doesn't. This prevents using controls on V4L2 M2M devices. Fix it by populating controls in setFd(), which is called by open().

RkISP actually supports two modes for color means, RGB and YCbCr. The variables where the means are stored are identically named regardless of the color means mode that's been selected. Since the gains are computed in RGB mode, a conversion needs to be done when the mode is YCbCr, which is unnecessary when RGB mode is selected. This adds support for RGB means mode too, by checking at runtime which mode is selected at a given time. The default is still set to YCbCr mode for now.

2022-09-28ipa: rkisp1: awb: Store per-frame information in frame contextLaurent Pinchart
Rework the algorithm's usage of the active state and frame context to store data in the right place. The active state stores two distinct categories of information: - The consolidated value of all algorithm controls. Requests passed to the queueRequest() function store values for controls that the application wants to modify for that particular frame, and the queueRequest() function updates the active state with those values. The active state thus contains a consolidated view of the value of all controls handled by the algorithm. - The value of parameters computed by the algorithm when running in auto mode. Algorithms running in auto mode compute new parameters every time statistics buffers are received (either synchronously, or possibly in a background thread). The latest computed value of those parameters is stored in the active state in the process() function. The frame context also stores two categories of information: - The value of the controls to be applied to the frame. These values are typically set in the queueRequest() function, from the consolidated control values stored in the active state. The frame context thus stores values for all controls related to the algorithm, not limited to the controls specified in the corresponding request, but consolidated from all requests that have been queued so far. For controls that can be specified manually or computed by the algorithm depending on the operation mode (such as the colour gains), the control value will be stored in the frame context in queueRequest() only when operating in manual mode. When operating in auto mode, the values are computed by the algorithm and stored in the frame context in prepare(), just before being stored in the ISP parameters buffer. The queueRequest() function can also store ancillary data in the frame context, such as flags to indicate if (and what) control values have changed compared to the previous request. - Status information computed by the algorithm for a frame. For instance, the colour temperature estimated by the algorithm from ISP statistics calculated on a frame is stored in the frame context for that frame in the process() function. The active state and frame context thus both contain identical members for most control values, but store values that have a different meaning.

Script properties are specified in the 'properties' section before the actual list of controls specified in the 'frames' section. Define a first 'loop' property that allows repeating the frame list periodically. All the frame ids in the 'frames' section shall be smaller than the loop control. Modify the capture script example to show usage of the 'loop' property and better document the frames list while at it.

2022-09-15libcamera: ipa_manager: Fix build without opensslMatthias Fend
Since commit bedef55d9500 ("libcamera: pub_key: Gracefully handle failures to load public key") the build will fail if openssl is not found on the host system. Use the existing HAVE_IPA_PUBKEY define to avoid accessing pubKey_ which does not exist when building without openssl.

2022-09-15meson: Enable vimc IPA for testsUmang Jain
Vimc pipeline handler is enabled unconditionally if the meson config option '-Dtest' is true. However, this is not true for the vimc IPA. Hence, a meson configuration such as: -Dpipelines=raspberrypi -Dipas=raspberrypi -Dtest=true will include the vimc pipeline handler (in addition to raspberrypi) but will skip the vimc IPA which can lead to failure of unit tests that depends on vimc to execute. One such unit test was identified as a result of this issue on RaspberryPi: ERROR IPAModule ipa_module.cpp:278 ipa_vimc.so: Failed to open IPA library: No such file or directory test IPA module src/ipa/vimc/ipa_vimc.so is invalid due to the non-existent ipa_vimc.so. Fix this by including the vimc IPA unconditionally when the tests are enabled, similar to how the vim pipeline-handler is included.
