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 period. This type of scheduling is advantageous for robotics, media players and recorders, as well as virtual machine guest management. This talk will discuss how to implement an application that uses SCHED_DEADLINE as well various issues that one must cope with. This scheduling class is rather new to Linux and still has some issues left to solve. Those will also be discussed as well as some ways to work around those issues.
