2024-01-09hooks: pre-push: Disable interpretation of escape sequencesKieran Bingham
The pre-push hook validates the commit messages utilising 'echo' to send the captured data from the git commit through grep. Commit messages may occasionally contain strings that could appear to be escape sequences such as doxygen style references to \struct. The '\' 'c' escape sequence can be interpreted to supress all further output [0] which then breaks the processing and string matching. Unfortunatley for us, doxygen's class reference constructed in the same form as \struct can be interpreted as the escape sequence to supress further output. [0] https://www.gnu.org/software/bash/manual/bash.html#Bash-Builtins Update the pre-push hook to explicitly disable escape sequence interpretation using the '-E' flag. This is not available on the posix-compliant shell 'dash', so also switch to bash explicitly to prevent potential failures.

2024-01-09ipa: rpi: vc4: data: Update tuning files for HDRDavid Plowman
All the Raspberry Pi official camera tuning files are updated for HDR. As stated previously, there is no mechanism in the hardware for combining images so all this does is enable multi-channel AGC to produce short and long exposure frames. It will be up to the application to deal with them. The changes are identical in every tuning file. 1. The existing AGC tuning is duplicated twice so that we have 3 AGC channels. 2. The first is left alone (the default AGC channel), the second is tweaked to under-expose significantly (ev -3) and the final one is tweaked to over-exposure slightly (ev +0.5) 3. Control parameters are provided to the "rpi.hdr" algorithm to associate these AGC channels correctly with the HDR modes.

2024-01-09utils: raspberrypi: ctt: Improve the Macbeth Chart search reliabilityDavid Plowman
Previously the code would brighten up images in case the Macbeth Chart is slightly dark, and also zoom in on sections of it to look for charts occupying less of the field of view. But it would not do both together. This change makes the search for smaller charts also repeat that search for the brightened up images that it made earlier, thereby increasing the chances of success for non-optimal tuning images. There are also a couple of very small drive-by typo fixes.

The gst_clear_event() function used by libcamerasrc has been introduced in GStreamer 1.16, while libcamera claims to need 1.14 or newer. This causes a compilation error. Fix it by copying the gst_clear_event() implementation to gstlibcamera-utils.h when compiling with older GStreamer version. The version check makes it clear that the workaround is needed with older versions only, flagging it for removal when the minimum GStreamer version requirement will be bumped.

Nonetheless, the 'i' variable is indeed unused. It turns out that the code can be simplified, as the commit that removed usage of the variable kept the now unneeded utils::enumerate() call.

2023-12-08meson: Replace hack with usage of '@BASENAME@'Laurent Pinchart
Starting with meson 0.59, the custom_target() function substitutes '@BASENAME@' in the output parameter with the input file name, with the extension removed. This is exactly what we implement manually when generating the IPA interface .cpp files. Furthermore, starting with meson 0.60, the 'name' positional parameter to the custom_target() function is optional, and defaults to the basename of the output file (including the extension). This is exactly the name we compute manually and pass to the function. As libcamera requires meson 0.60 or newer, we can depend on those two features and drop manual computation of the base name. This fixes a warning with recent meson versions that complain that passing a file object to the format() function is a broken feature: WARNING: Broken features used: * 1.3.0: {'str.format: Value other than strings, integers, bools, options, dictionaries and lists thereof.'} Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
