The utils::hex() function is implemented for 32-bit and 64-bit integers, but not for 8-bit and 16-bit. This causes a link error (possibly at runtime for IPA modules due to lazy linking) when trying to print 8-bit or 16-bit integers. Implement additional specializations to fix it.

2024-07-03ipa: rkisp1: Move ov4689 and ov5640 black levels into sensor helpersStefan Klug
Move black levels for tuning files that contained a BLC block into the camera sensor helpers. ov4689.yaml had 66@12bit while the datasheet states 64@12bit. Use the value from the datasheet (scaled to 16bit). ov5640.yaml had 256@12bit while the datasheet states 16@10bit. Looking at the commit message the 256 most likely stems from the imx219 tuning file and 16@10bit is the same as the 64@12bit from the ov4689. This seems more likely and is therefore used.

As the camera sensor helper now has the ability to provide the black level, use it. Black levels can still be overwritten by the tuning file, but the direction is to remove them from the tuning files and move them into the sensor helpers. Additionally interpret all values based on 16bits. The conversion to the scale required by the hardware is done in process(). It ensures all the values inside libcamera are the same scale and is in preparation for the i.MX8MP where black levels are based on a 20bit scale. Note that this breaks existing tuning files. The tuning files distributed with libcamera will be fixed in a later patch.

2024-07-03libcamera: converter: Replace usage of stream index by Stream pointerUmang Jain
The converter interface uses the unsigned int output stream index to map to the output frame buffers. This is cumbersome to implement new converters because one has to keep around additional book keeping to track the streams with their correct indexes. The v4l2_converter_m2m and simple pipeline handler are adapted to use the new interface. This work roped in software ISP as well, which also seems to use indexes (although it doesn't implement converter interface) because of a common conversionQueue_ queue used for converter_ and swIsp_. The logPrefix is no longer able to generate an index from a stream, and is updated to be more expressive by reporting the stream configuration instead, for example, reporting "1920x1080-MJPEG" in place of "stream0".

The ipaCreate() function is the entry point to IPA modules. It is declared in ipa_interface.h, and defined by each module. As the function is defined with extern "C" linkage, the namespace in which it is contained is not very relevant from a caller's point of view. For the IPA module implementer, however, defining the function in the libcamera namespace avoids adding an explicit libcamera:: prefix to the symbols used by the function. This is why all IPA modules define their ipaCreate() entry point in the libcamera namespace. The ipa_interface.h file, however, declares the function in the global namespace.
