2021-08-19test: camera: Camera reconfiguration and fd-leak testUmang Jain
Development and usage of isolated IPA's has identified bugs in the transmission of the file descriptors between the pipeline handler and the IPA through. Add tests to identify these bugs and prevent regressions. This tests basically checks for two things: - Camera reconfigurations without stopping CameraManager - Fd leaks across IPA IPC boundary [1] Currently, it uses vimc, but can be easily changed to using another platform (for e.g. IPU3) by changing kCamId_ and kIpaProxyName_. The test performs kNumOfReconfigures_ (currently set to 10) reconfigurations of the camera. Each reconfiguration runs start(), capture(100ms), stop() of the camera. Hence, the test runs approximately for 1 second. For checking the fd leaks, the test monitors the /proc/$PROXY_PID/fd directory for open fds. It compares the number of open fds after each run to the number of open fds before the first run. If those two are found to be mis-matched, the test shall report failure. The test validates IPA IPC code paths which are used when the IPA is run in isolated mode. The CameraTest is constructed with the isolate flag set to enforce this.

2021-06-25libcamera/base: Validate internal headers as privateKieran Bingham
Headers which must not be exposed as part of the public libcamera API should include base/private.h. Any interface which includes the private.h header will only be able to build if the libcamera_private dependency is used (or the libcamera_base_private dependency directly). Build targets which are intended to use the private API's will use the libcamera_private to handle the automatic definition of the inclusion guard.

2021-02-11meson: Fix coding style when declaring arraysLaurent Pinchart
The meson.build files mix array declarations with and without a space after the opening and before the closing square bracket. The vast majority of cases don't use spaces, so standardize on that. While it it, fix indentation in a few places.

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.

2019-11-20test: Extract CameraTest class out of camera tests to libtestLaurent Pinchart
Many tests other than the camera/ tests use a camera. To increase code sharing, move the base CameraTest class to the test library. The class becomes a helper that doesn't inherit from Test anymore (to avoid diamond inheritance issues when more such helpers will exist).

2019-07-14test: camera: Add buffer import and mapping testJacopo Mondi
Test buffer importing and mapping by streaming the VIMC camera to VIVID video output device performing zero-copy memory sharing using dmabuf file descriptors. The test cycle 20 buffers between the camera and the output with a 1:1 buffer index to dmabuf fd mapping, then randomises the mapping with the same number of buffers on each side for 20 more frames, to finally increase the number of buffers on the output side for the 20 last frames. No remapping of dmabuf fd to buffer index should occur for the first 40 frames.

Instead of manually adding the libcamera library and include path to every target that requires it, declare a dependency that groups the headers as source, the library and the include path, and use it through the project.

The test exercises all states of the camera and verifies that only the intended operations are possible at each stage.

Correctly configure the camera using the default configuration and run a capture session for 100 milliseconds, which is plenty of time, in tests over 600 requests completed using the vimc pipeline. The test passes if at least the number of buffers used in the capture times two number of requests completes to prove we cycle through all buffers.
