Deadline Scheduling in the Linux Kernel

At the last Real-Time Linux Workshop held on September in Dresden, there has been a lot of discussion about the possibility of enhancing real-time capabilities of Linux by adding a new scheduling class to the Linux kernel. According to most kernel developers, this new scheduling class should be based on the Earliest Deadline First real-time algorithm. The first draft of the scheduling class has been called “SCHED_EDF” and it has been proposed and discussed on the Linux Kernel Mailing List just before the workshop. Recently, a second version of the scheduling class (called “SCHED_DEADLINE”, to meet the request of some kernel developers) has been proposed. Moreover, the code has been moved to a public git repository on Gitorius.
