2020-05-18(q)cam: Fix header guardsLaurent Pinchart
Several headers belonging to cam and qcam use __LIBCAMERA_*_H__ as a header guard. They're not part of the libcamera core, use __CAM_*_H__ and __QCAM_*_H__ instead, similarly to all other headers of cam and qcam.

2020-05-18libcamera: v4l2_videodevice: Fix dangling file descriptorNaushir Patuck
The FileDescriptor constructor used in V4L2VideoDevice::exportDmabufFd() creates a duplicate of the fd to store in the object. The original fd returned by the VIDIOC_EXPBUF ioctl was never closed, and left dangling. This would cause out of memory conditions if the camera stream was repeatedly started and stopped. This change closes the original fd explicitly, fixing the leak.

2020-05-18meson: Rename variables storing headers listsLaurent Pinchart
The list of public, IPA and internal header files are stored in three meson variables, named libcamera_api, libcamera_ipa_api and libcamera_headers respectively. The lack of uniformity is a bit confusing. Fix it by renaming those variables to libcamera_public_headers, libcamera_ipa_headers and libcamera_internal_headers.

2020-05-16libcamera: Move IPA headers from include/ipa/ to include/libcamera/ipa/Laurent Pinchart
The IPA headers are installed into $prefix/include/libcamera/ipa/, but are located in the source tree in include/ipa/. This requires files within libcamera to include them with #include <ipa/foo.h> while a third party IPA would need to use #include <libcamera/ipa/foo.h> Not only is this inconsistent, it can create issues later if IPA headers need to include each other, as the first form of include directive wouldn't be valid once the headers are installed. Fix the problem by moving the IPA headers to include/libcamera/ipa/. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Jacopo Mondi <jacopo@jmondi.org>
2020-05-16libcamera: Move internal headers to include/libcamera/internal/Laurent Pinchart
The libcamera internal headers are located in src/libcamera/include/. The directory is added to the compiler headers search path with a meson include_directories() directive, and internal headers are included with (e.g. for the internal semaphore.h header) #include "semaphore.h" All was well, until libcxx decided to implement the C++20 synchronization library. The __threading_support header gained a #include <semaphore.h> to include the pthread's semaphore support. As include_directories() adds src/libcamera/include/ to the compiler search path with -I, the internal semaphore.h is included instead of the pthread version. Needless to say, the compiler isn't happy. Three options have been considered to fix this issue: - Use -iquote instead of -I. The -iquote option instructs gcc to only consider the header search path for headers included with the "" version. Meson unfortunately doesn't support this option. - Rename the internal semaphore.h header. This was deemed to be the beginning of a long whack-a-mole game, where namespace clashes with system libraries would appear over time (possibly dependent on particular system configurations) and would need to be constantly fixed. - Move the internal headers to another directory to create a unique namespace through path components. This causes lots of churn in all the existing source files through the all project. The first option would be best, but isn't available to us due to missing support in meson. Even if -iquote support was added, we would need to fix the problem before a new version of meson containing the required support would be released. The third option is thus the only practical solution available. Bite the bullet, and do it, moving headers to include/libcamera/internal/.

2020-05-13licenses: License all meson files under CC0-1.0Laurent Pinchart
In an attempt to clarify the license terms of all files in the libcamera project, the build system files deserve particular attention. While they describe how the binaries are created, they are not themselves transformed into any part of binary distributions of the software, and thus don't influence the copyright on the binary packages. They are however subject to copyright, and thus influence the distribution terms of the source packages. Most of the meson.build files would not meet the threshold of originality criteria required for copyright protection. Some of the more complex meson.build files may be eligible for copyright protection. To avoid any ambiguity and uncertainty, state our intent to not assert copyrights on the build system files by putting them in the public domain with the CC0-1.0 license.

The proxy worker is licensed under the GPL. It is compiled as a binary separate from libcamera.so, and it is our understanding and intent that the GPL license doesn't propagate to libcamera.so. However, as the worker is executed by libcamera.so, the GPL license may cause concerns in this context, regardless of whether the concerns are valid or not.

The simple pipeline handler rejects devices that have multiple capture video nodes. There's no real reason to do so, a more dynamic approach is possible as the pipeline handler already locates the video device by walking the media graph. Rework the match sequence by skipping any check on the video nodes, and create the V4L2VideoDevice for the media entity at the end of the pipeline when initializing the camera data. The V4L2VideoDevice instances are managed by the pipeline handler itself, to avoid creating separate instances in the camera data if multiple sensors are routed to the same video device.

2020-05-10libcamera: pipeline: Add a simple pipeline handlerMartijn Braam
This new pipeline handler aims at supporting any simple device without requiring any device-specific code. Simple devices are currently defined as a graph made of one or multiple camera sensors and a single video node, with each sensor connected to the video node through a linear pipeline. The simple pipeline handler will automatically parse the media graph, enumerate sensors, build supported stream configurations, and configure the pipeline, without any device-specific knowledge. It doesn't support configuration of any processing in the pipeline at the moment, but may be extended to support simple processing such as format conversion or scaling in the future. The only device-specific information in the pipeline handler is the list of supported drivers, required for device matching. We may be able to remove this in the future by matching with the simple pipeline handler as a last resort option, after all other pipeline handlers have been tried.

2020-05-03libcamera: camera_sensor: Relax restriction on sizesLaurent Pinchart
The CameraSensor class assumes that camera sensors support the exact same list of sizes of all media bus codes. While allowing a simpler API, this assumption is incorrect and is blocking usage of some camera sensors. Relaxing the constraint is possible without changes to the CameraSensor API syntax, but requires changing its semantics. The sizes() function now returns the list of all sizes for all media bus codes, and the getFormat() function now searches in all supported media bus codes. The former is likely not the most useful option for pipeline handlers, but the sizes() function is currently unused. Designing a better API will require inspecting current and expected future use cases in pipeline handlers to determine proper heuristics. While at it, fix a small typo in an unrelated comment.
