Hello, I have found in https://wiki.linuxfoundation.org/realtime/documentation/howto/applications/cyclic that there is EDF scheduler option for creating a periodic RT thread. Yet, I could not understand what's behind the EDF scheduler. Is it using posix or non-posix timer ? I have also found the following information: http://lxr.free-electrons.com/source/Documentation/scheduler/sched-deadline.txt Yet it does not provide more details about the timer used with EDF.
