From 026b3af8c2154ad2670528dc4ca7703ca15a64cc Mon Sep 17 00:00:00 2001 From: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Date: Sat, 18 Jan 2020 03:44:49 +0200 Subject: libcamera: log: Print the thread ID in the log MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The current thread ID is useful when debugging concurrency issues. Print it in log messages. The syslog target is left out as the thread ID would have little use there, and partly duplicates the process ID. The log messages now look as follows.
