2021-11-24	libcamera: base: Convert to pragma once	Kieran Bingham
	Remove the verbose #ifndef/#define/#endif pattern for maintaining header idempotency, and replace it with a simple #pragma once. This simplifies the headers, and prevents redundant changes when header files get moved.

2021-10-15	libcamera: base: backtrace: Fallback to libunwind for symbolic names	Laurent Pinchart
	libunwind has an API to provide symbolic names for functions. It's less optimal than using backtrace_symbols() or libdw, as it doesn't allow deferring the symbolic names lookup, but it can be usefull as a fallback if no other option is available. A sample backtrace when falling back to libunwind looks like libcamera::VimcCameraData::init()+0xbd libcamera::PipelineHandlerVimc::match(libcamera::DeviceEnumerator)+0x3e0 libcamera::CameraManager::Private::createPipelineHandlers()+0x1a7 libcamera::CameraManager::Private::init()+0x98 libcamera::CameraManager::Private::run()+0x9f libcamera::Thread::startThread()+0xee decltype((std::__1::forward<libcamera::Thread>(fp0)).fp()) std::__1::__invoke<void (libcamera::Thread::)(), libcamera::Thread, void>(void (libcamera::Thread::&&)(), libcamera::Thread&&)+0x77 void std::__1::__thread_execute<std::__1::unique_ptr<std::__1::__thread_struct, std::__1::default_delete<std::__1::__thread_struct> >, void (libcamera::Thread::)(), libcamera::Thread, 2ul>(std::__1::tuple<std::__1::unique_ptr<std::__1::__thread_struct, std::__1::default_delete<std::__1::__thread_struct> >, void (libcamera::Thread::)(), libcamera::Thread>&, std::__1::__tuple_indices<2ul>)+0x3e void* std::__1::__thread_proxy<std::__1::tuple<std::__1::unique_ptr<std::__1::__thread_struct, std::__1::default_delete<std::__1::__thread_struct> >, void (libcamera::Thread::)(), libcamera::Thread> >(void*)+0x62 start_thread+0xde ???

2021-10-15	libcamera: base: backtrace: Use libunwind when available	Laurent Pinchart
	libunwind is an alternative to glibc's backtrace() to extract a backtrace. Use it when available to extend backtrace support to more platforms. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2021-10-15	libcamera: base: Add Backtrace class	Laurent Pinchart
	Create a new class to abstract generation and access to call stack backtraces. The current implementation depends on the glibc backtrace() implementation and is copied from the logger. Future development will bring support for libunwind, transparently for the users of the class. The logger backtrace implementation is dropped, replaced by usage of the new Backtrace class.
