From fcc6d4bd76874585336cb0bbbd369702b59515d2 Mon Sep 17 00:00:00 2001 From: Paul Elder Date: Mon, 19 Oct 2020 19:18:17 +0900 Subject: libcamera: tracing: Implement tracing infrastructure Implement tracing infrastructure in libcamera. It takes .tp files, as required by lttng, and generates a tracepoint header and C file, as lttng requires. meson is updated accordingly to get it to compile with the rest of libcamera. Update the documentation accordingly.
