2020-02-24tests: Remove IPA_MODULE_PATH environment variableKieran Bingham
The tests declare a hard-coded LIBCAMERA_IPA_MODULE_PATH to allow tests to run from the test-suite. This requires tests to be run only from the root of the build directory, otherwise (for example, by running in their local directory) they will not be able to correctly locate the IPA modules. Now that the build path for the IPA manager is determined at runtime we can remove the redundant setting of the LIBCAMERA_IPA_MODULE_PATH for tests.

2020-02-24libcamera: ipa_manager: Search for IPA libraries in build treeKieran Bingham
When libcamera is built and tested (or used at all) before installing to the configured prefix path, it will be unable to locate the IPA binaries, or IPA binaries previously installed in the system paths may be incorrect to load. Utilise the build_rpath dynamic tag which is stripped out by meson at install time to determine at runtime if the library currently executing has been installed or not. When not installed and running from a build tree, identify the location of that tree by finding the path of the active libcamera.so itself, and from that point add a relative path to be able to load the most recently built IPA modules.

2020-02-19libcamera: media_device: prevent sign extension on castsKieran Bingham
The conversion of pointers to integers is implementation defined and differs between g++ and clang++ when utilising a uint64_t type. #include <iostream> int main(int argc, char **argv) { void *ptr = reinterpret_cast<void *>(0xf1234567); uint64_t u64 = reinterpret_cast<uint64_t>(ptr); uint64_t uint64 = reinterpret_cast<uintptr_t>(ptr); std::cout << "ptr " << ptr << " ptr -> u64 0x" << std::hex << u64 << " ptr -> uintptr_t -> u64 0x" << std::hex << uint64 << std::endl; return 0; } When compiled with g++ for a 32-bit platform produces the following unexpected output: ptr 0xf1234567 ptr -> u64 0xfffffffff1234567 ptr -> uintptr_t -> u64 0xf1234567 The standards states: "A pointer can be explicitly converted to any integral type large enough to hold all values of its type. The mapping function is implementation-defined. [Note: It is intended to be unsurprising to those who know the addressing structure of the underlying machine. — end note]" And as such the g++ implementation appears to be little more surprising than expected in this situation. The MediaDevice passes pointers to the kernel via the struct media_v2_topology in which pointers are cast using a uint64 type (__u64), which is affected by the sign extension described above when BIT(32) is set and causes an invalid address to be given to the kernel. Ensure that we cast using uintptr_t which is not affected by the sign extension issue. Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>

2020-02-13libcamera: camera_manager: Run the camera manager in a threadLaurent Pinchart
Relying on the application event loop to process all our internal events is a bad idea for multiple reasons. In many cases the user of libcamera can't provide an event loop, for instance when running through one of the adaptation layers. The Android camera HAL and V4L2 compatibility layer create a thread for this reason, and the GStreamer element would need to do so as well. Furthermore, relying on the application event loop pushes libcamera's realtime constraints to the application, which isn't manageable. For these reasons it's desirable to always run the camera manager, the pipeline handlers and the cameras in a separate thread. Doing so isn't too complicated, it only involves creating the thread internally when starting the camera manager, and synchronizing a few methods of the Camera class. Do so as a first step towards defining the threading model of libcamera. The event dispatcher interface is still exposed to applications, to enable cross-thread signal delivery if desired.
