Earliest deadline first scheduling algorithm

WebThe SCHED_DEADLINE policy contained inside the sched_dl scheduling class is basically an implementation of the Earliest Deadline First (EDF) scheduling algorithm, augmented with a mechanism (called Constant Bandwidth Server, CBS) that makes it possible to isolate the behavior of tasks between each other. WebWhere deadlines are involved, an earliest-deadline-first (EDF) scheduling algorithm may be used. Another algorithm is called least-slack-time first: the process with the least available waiting time left is scheduled first. Either of these may also be used to schedule periodic processes. EDF will tend to favor high-frequency processes.
