2020-08-05libcamera: ipa: raspberrypi: ALSC: Camera mode does not need to be atomicDavid Plowman
In the libcamera framework, SwitchMode (which overwrites the camera_mode) cannot run concurrently with Prepare (which uses it).

2020-07-17libcamera: pipeline: ipa: raspberrypi: Use dma heap allocs for LS tablesNaushir Patuck
Remove use of vcsm allocations and replace with dma heap allocations. The pipeline handler now passes the fd of the allocation over to the IPA instead of the raw pointer. Also use libcamera::FileDescriptor for fd lifetime management. This commit must be built alongside the accompanying BCM2835 ISP kernel driver changes at https://github.com/raspberrypi/linux/pull/3715. Otherwise a mismatch will cause undefined behavior.

2020-07-17ipa: raspberrypi: Pass sensor config back from configure()Laurent Pinchart
The Raspberry Pi IPA uses the custom RPI_IPA_ACTION_SET_SENSOR_CONFIG frame action to send the sensor staggered write configuration to the pipeline handler when the IPA is configured. Replace this ad-hoc mechanism by passing the corresponding data back from the IPA to the pipeline handler through the configure() response. This allows synchronous handling of the response on the pipeline handler side.

Add two new parameters, ipaConfig and result, to the IPAInterface::configure() function to allow pipeline handlers to pass custom data to their IPA, and receive data back. Wire this through the code base. The C API interface will be addressed separately, likely through automation of the C <-> C++ translation.

2020-06-22libcamera: ipa: raspberrypi: Recalculate camera exposure/gain when camera ↵David Plowman
mode changes This commit causes the AGC to recalculate its camera exposure/gain values when the camera mode changes. For example it's possible that the exposure profile could be changed by the application so the division between exposure time and analogue gain may be different. The other underlying reason (and which this commit accomplishes too) is that the sensor's line timing may change in a new mode, and because V4L2 drivers store a number of exposure _lines_, the resulting _time_ will "change under our feet". So we have to go through the process of recalculating the correct number of lines and writing this back to the sensor with every mode switch, regardless of anything else.

This commit adds a Metadata parameter to the SwitchMode method enabling it to return camera and other settings to the caller (usually the configure method, just after the camera mode has been selected). In future this will allow the Raspberry Pi IPAs to take those settings (such as exposure and analogue gain) and program them directly into the camera or ISP before the camera is even started.

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.
