2024-05-08libcamera: Drop file name from header comment blocksLaurent Pinchart
Source files in libcamera start by a comment block header, which includes the file name and a one-line description of the file contents. While the latter is useful to get a quick overview of the file contents at a glance, the former is mostly a source of inconvenience. The name in the comments can easily get out of sync with the file name when files are renamed, and copy & paste during development have often lead to incorrect names being used to start with. Readers of the source code are expected to know which file they're looking it. Drop the file name from the header comment block. The change was generated with the following script: ---------------------------------------- dirs="include/libcamera src test utils" declare -rA patterns=( ['c']=' \* ' ['cpp']=' \* ' ['h']=' \* ' ['py']='# ' ['sh']='# ' ) for ext in ${!patterns[@]} ; do files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done) pattern=${patterns[${ext}]} for file in $files ; do name=$(basename ${file}) sed -i "s/^\(${pattern}\)${name} - /\1/" "$file" done done ---------------------------------------- This misses several files that are out of sync with the comment block header. Those will be addressed separately and manually. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Daniel Scally <dan.scally@ideasonboard.com>
2022-10-24ipa: Pass metadata to Algorithm::process() functionLaurent Pinchart
Extend the Algorithm::process() function with a metadata control list, to be filled by individual algorithms with frame metadata. Update the rkisp1 and ipu3 IPA modules accordingly, and drop the dead code in the IPARkISP1::prepareMetadata() function while at it. This only creates the infrastructure, filling metadata in individual algorithms will be handled separately.

2022-09-27ipa: libipa: Pass a reference instead of pointer to Algorithm::process()Laurent Pinchart
Frame contexts will become the core component of IPA modules, always available to functions of the algorithms. To indicate and prepare for this, turn the frame context pointer passed to Algorithm::process() into a reference. The RkISP1 IPA module doesn't use frame contexts yet, so pass a dummy context for now. While at it, drop an unneeded [[maybe_unused]] from Agc::process() and add a missing parameter documentation for the frameContext argument to Awb::process().

2022-05-18ipa: libipa: Add frame context pointer in process()Umang Jain
Currently we have a single structure of IPAFrameContext but subsequently, we shall have a ring buffer (or similar) container to keep IPAFrameContext structures for each frame. It would be a hassle to query out the frame context required for process() (since they will reside in a ring buffer) by the IPA for each process. Hence, prepare the process() libipa template to accept a particular IPAFrameContext early on. As for this patch, we shall pass in the pointer as nullptr, so that the changes compile and keep working as-is.

2021-11-24ipa: ipu3: Convert to pragma onceKieran Bingham
Remove the verbose #ifndef/#define/#endif pattern for maintaining header idempotency, and replace it with a simple #pragma once. This simplifies the headers, and prevents redundant changes when header files get moved.

2021-08-20ipa: ipu3: Introduce a modular tone mapping algorithmJean-Michel Hautbois
Introduce a new algorithm to manage the tone mapping handling of the IPU3. The initial algorithm is chosen to configure the gamma contrast curve which moves the implementation out of AWB for simplicity. As it is initialised with a default gamma value of 1.1, there is no need to use the default table at initialisation anymore. This demonstrates the way to use process() call when the EventStatReady comes in. The function calculates the LUT in the context of a frame, and when prepare() is called, the parameters are filled with the updated values. AGC is modified to take the new process interface into account.
