Since VCM for surface Go 2 (dw9719) had been successfully driven, this Af module can be used to control the VCM and determine the focus value based on the IPU3 AF state. Based on the values from the IPU3 AF buffer, the variance of each focus step is determined and a greedy approach is used to find the maximum variance of the AF state and an appropriate focus value. The grid configuration is implemented as a context. Also, the grid parameter- AF_MIN_BLOCK_WIDTH is set to 4 (default is 3) since if the default value is used, x_start (x_start > 640) will be at an incorrect location of the image (rightmost of the sensor).

While it is possible to allow the implementation to let objects connect to a specific signal multiple times, there are no expected use cases for this in libcamera and this behaviour is restricted to favour defensive programming by raising an error when this occurs.

2022-02-03lc-compliance: Only download gtest subproject as a fallbackJavier Martinez Canillas
Currently, a subproject is used to fetch gtest dependency unconditionally for any Linux distribution besides ChromeOS. But it leads to a regression in distros whose builders are not allowed to download files during build. This change was introduced by commit 0d50a04cc918 ("lc-compliance: Build with gtest in subprojects") and the rationale is that some distros, such as Debian ship libgtest-dev as a static library. And this could be built with a different toolchain than the one used to build libcamera itself. But this seems to be a corner case, usually users will either build both libcamera and all its dependencies using the same toolchain or build it using both the libgtest library and toolchain as provided by the distro. If someone doesn't want for meson to pick up the non-compatible static library provided by the distro, then instead should make sure that their build root does not have the package providing this installed. Let's simplify the logic to find the dependency and just use the built-in support in dependency() function to fallback to a subproject if not found. This covers to common case of attempting to use the gtest provided by the system or pulling from source if not found or is not preferred. To force meson to fallback to the wrap for gtest you can use this command: meson configure -Dforce_fallback_for=gtest and to force fallback for all the dependencies, you can use the following: meson build --wrap-mode=forcefallback Fixes: commit 0d50a04cc918 ("lc-compliance: Build with gtest in subprojects") Reported-by: Eric Curtin <ecurtin@redhat.com> Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Hirokazu Honda <hiroh@chromium.org> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2022-02-01pipeline: raspberrypi: Fix the buffer count calculation for the ISP input streamNaushir Patuck
The ISP input stream currently only allocates a single slot in the V4L2VideoDevice cache as it follows the number of buffers allocated for use. However, this is wrong as the ISP input stream imports buffers from Unicam image stream. As a consequence of this, only one cache slot was used during runtime for the ISP input stream, and if multiple buffers were to be queued simultaneously, the queue operation would return a failure. Fix this by passing the same number of RAW buffers available from the Unicam image stream. Additionally, double this count in the cases where buffers could be allocated externally from the application.

2022-01-21v4l2: V4L2CameraProxy: Add support for PREPARE_BUF as one of the supported ioctlVedant Paranjape
Add support for PREPARE_BUF as one of the ioctl. Since this is a compat layer, there doesn't seem to be an equivalent to the "transfer ownership of the buffer to kernel driver" in V4L2Camera class. Thus, simply duplicate the checks done by vidioc_qbuf. To match the error checks done by kernel implementation, we'd have to check if dmabuf fd is valid and that the buffer size is large enough. Doing so will not add any particular value to the program as applications most likely don't depend on these conditions being handled correctly.

The fence and mapped-buffer tests both use the VIMC test device and must not be run at the same time. Split these tests to a new group to force their isolation from running in parallel.

2022-01-19pipeline: raspberrypi: Return all ISP resolutions from generateConfiguration()Naushir Patuck
The libcamerasrc gstreamer component does seem to not allow stream resolutions that are not advertised by PipelineHandler::generateConfiguration(). This has been raised in a bug report [1]. Fix this behavior by advertising a SizeRange from the minimum ISP resolution, up to the sensor resolution from PipelineHandlerRPi::generateConfiguration().
