Linux kernel process schedulers

SCHED DEADLINE

SCHED_DEADLINE is a CPU scheduler available in the Linux kernel since version 3.14, based on the Earliest Deadline First (EDF) and Constant Bandwidth Server (CBS) algorithms, supporting resource reservations: each task scheduled under such policy is associated with a budget Q (aka runtime), and a period P, corresponding to a declaration to the kernel that Q time units are required by that task every P time units, on any processor. This makes SCHED_DEADLINE particularly suitable for real-time applications, like multimedia or industrial control, where P corresponds to the minimum time elapsing between subsequent activations of the task, and Q corresponds to the worst-case execution time needed by each activation of the task. (Wikipedia).

Embedded Recipes 2017 - Understanding SCHED_DEADLINE - Steven Rostedt

Starting in Linux version 3.14, a new scheduling class was introduced. This class is called SCHED_DEADLINE. It implements Earliest Deadline First (EDF) along with a Constant Bandwidth Scheduler (CBS) that is used to give applications a guaranteed amount of CPU for a periodic time frame. T
