This is useful on Linux distributions where normal users are not allowed to access /dev/dma_heap/* while they are allowed to access /dev/udmabuf.

2024-06-04libcamera: DmaBufAllocator: Support allocating from /dev/udmabufHans de Goede
The dma-buf allocator currently allocates from CMA and system heaps. Extend the dma-buf allocator to support allocating dma-buffers by creating memfd-s and turning those into dma-buffers using /dev/udmabuf. The buffers allocated through memfd/udmabuf are not suitable for zero-copy buffer sharing with other devices.

2024-06-04libcamera: Rename DmaHeap class to DmaBufAllocatorHans de Goede
Users of the DmaHeap class really just want some way to allocate dma-buffers from userspace. This can also be done by using /dev/udmabuf instead of using /dev/dma_heap/*. Rename DmaHeap class to DmaBufAllocator in preparation of adding /dev/udmabuf support. And update the DmaHeap class docs to match including replacing references to "dma-heap type" with "dma-buf provider". This is a pure automated rename on the code ('s/DmaHeap/DmaBufAllocator/') + file renames + doc updates. There are no functional changes. The DmaBufAllocator objects in vc4.cpp and software_isp.cpp are left named dmaHeap_ to keep the changes to those 2 files to a minimum.

The subdev embedded data support series includes a change to the VIDIOC_SUBDEV_G_ROUTING and VIDIOC_SUBDEV_S_ROUTING ioctls that impacts the userspace API. Update to the new API, while preserving backward compatibility to ease the transition. Document the backward compatibility to only be supported for two kernel releases. As the routing API isn't enabled in any upstream kernel yet, users of the API need kernel patches, and are expected to be able to upgrade quickly.

2024-06-03test: fence: Fix race conditionLaurent Pinchart
The fence test is racy, as it relies on the main loop being executed between completion of request signalledRequestId_ and signalledRequestId_ + 1. This usually happens, but is not guaranteed. To fix the race condition, change the request identification logic by replacing usage of the cookie value, which is zero-based and wraps around at nbuffers_ - 1, with a completed request counter that is one-based and doesn't wrap. The completedRequestId_, expiredRequestId_ and signalledRequestId_ variables now track the identifier of the last request that has completed, the request whose fence will time out, and the request whose fence will be signalled.

2024-06-02libcamera: software_isp: Remove TODO about internal representationMilan Zamazal
TODO #4 was recorded at a time where the IPA module computed gain values and the ISP computed the look up tables. The gains were higher-level parameters. Now that the look up tables are computed in the IPA module, the IPA and ISP are more tightly coupled and the TODO item is less relevant. Let's drop the TODO item. We may or may not need to switch to a different representation in future but there is currently no good need for this and the conversion of the values would be just waste of CPU cycles.

2024-06-02libcamera: software_isp: Move color mappings out of debayeringMilan Zamazal
Constructing the color mapping tables is related to stats rather than debayering, where they are applied. Let's move the corresponding code to stats processing. The same applies to the auxiliary gamma table. As the gamma value is currently fixed and used in a single place, with the temporary exception mentioned below, there is no need to share it anywhere anymore. It's necessary to initialize SoftwareIsp::debayerParams_ to default values. These initial values are used for the first two frames, before they are changed based on determined stats. To avoid sharing the gamma value constant in artificial ways, we use 0.5 directly in the initialization. This all is not a particularly elegant thing to do, such a code belongs conceptually to the similar code in stats processing, but doing better is left for larger refactoring. This is a preliminary step towards building this functionality on top of libipa/algorithm.h, which should follow.

2024-06-02libcamera: software_isp: Honor black level in AWBMilan Zamazal
The white balance computation didn't consider black level. This is wrong because then the computed ratios are off when they are computed from the whole brightness range rather than the sensor range. This patch adjusts white balance computation for the black level. There is no need to change white balance application in debayering as this is already applied after black level correction. Exposure computation already subtracts black level, no changes are needed there.

2024-05-16ipa: rpi: Add HDR supportNaushir Patuck
Add support for the following HDR modes in the Raspberry Pi IPA: - Night mode - Single exposure mode - Multi-exposure (merged and unmerged) The algorithm is updated to expect the HDR short channel to meter explicitly for highlights. This means that it will not in general under-expose the short channel more than is actually necessary. When images don't have much saturation, it's good to detect this so that some of the boost we want to apply to the dark areas can be implemented as regular gain. This means we can then adjust the tone curve less, leading to less flat looking images. The impact on the HDR algorithm is then that this determines how we build tonemaps dynamically. The highlights are more-or-less correct now, so we have to build a power-type curve that gives us the appropriately configured targets in the lower part of the histogram. We allow the tuning file to supply the maximum spatial gain value, rather than the whole curve (though it can supply this if it wants). Some parameter defaults are tweaked to be generally better across the range of our cameras.

To match the enumerated media devices, each registered pipeline handler is used in no specific order. It is a limitation when several pipelines can match the devices, and user has to select a specific pipeline. For this purpose, environment variable LIBCAMERA_PIPELINES_MATCH_LIST is created to give the option to define an ordered list of pipelines to match on.

2024-05-14libcamera: pipeline: Rename pipelines to a shorter nameJulien Vuillaumier
The PipelineHandlerFactoryBase class has a name that is propagated to the PipelineHandler instance it creates. In present implementation, this name comes from the REGISTER_PIPELINE_HANDLER registration macro. It corresponds to the stringified name of the PipelineHandler derived class. Therefore, PipelineHandler factories and instances names can be quite long such as "PipelineHandlerRkISP1". A libcamera user may have to explicitly refer to a PipelineHandler name for configuration purpose: one usage of the name can be to define a pipeline handlers match list and their priorities. It is desired, for user convenience, to use a short name to designate a pipeline handler. Reusing the short pipeline names already defined in the meson option files is an existing and consistent way of naming pipelines. This change adds an explicit name parameter to the REGISTER_PIPELINE_HANDLER registration macro. That parameter is used to define the name of a pipeline handler factory, instead of the current pipeline handler class name. Each pipeline registration is updated accordingly. The short name assigned corresponds to the pipeline directory name in the source tree. It is consistent with pipelines names used in meson. Changing the pipeline name has an impact on the IPA modules: each module defines a IPAModuleInfo structure. This structure has a pipelineName member defining the pipeline handler name it shall match with. Therefore, each internal IPA module definition has to be changed to have its IPAModuleInfo pipelineName name updated with the short pipeline handler name. In addition to this pipelineName member, the IPAModuleInfo structure also has a name member, associated to the IPA module name. Having renamed the pipelines to a short name, the pipeline name and the IPA module names of the IPAModuleInfo structure are the same: for in-tree IPA, they correspond to the respective pipeline and IPA subdirectories in the source tree. However the IPA name could be different, for instance with a close source IPA implementation built out-of-tree. Thus, it makes sense to keep the IPA name in that structure, as the 2 definitions may not always be redundant.

A new Doxygen warning introduced in a recent commit went unnoticed, both in manual tests and in CI. Unlike C/C++ warnings that are treated as errors, we don't fail the build with Doxygen warnings. This is due to the fact that the libcamera documentation compiles cleanly only with quite recent versions of Doxygen. Enabling the WARN_AS_ERROR Doxygen option unconditionally could bother many users. To improve the situation, add a meson option to treat Doxygen warnings as errors. The option is disabled by default, preserving the current behaviour, and will be enabled in CI builds.
