| - | The initial idea of a Linux scheduling class based on the Earliest Deadline First (EDF) algorithm is born in the small context of the [[http://retis.sssup.it|Real-Time Systems (ReTiS) Lab of Scuola Superiore Sant'Anna]] and its Spin-Off company [[http://www.evidence.eu.com|Evidence Srl]]. Then, Claudio Scordino had the idea of using the patch within the [[http://www.actors-project.eu|ACTORS project]], financially supported by the European Commission. Through this project, company Evidence Srl was also able to finance and promote the development of the first versions of the patch. The code has been developed by Dario Faggioli (for the first three versions) and Juri Lelli (since the fourth version) with sporadic help from Michael Trimarchi. The patch has been periodically released to the kernel community through the Linux kernel mailing list (LKML). Each release aligned the code to the latest version of the kernel and took into account comments received at the previous submission. As the popularity of the scheduler increased, a higher number of kernel developers started providing their feedback and their contribution. | + | The initial idea of a Linux scheduling class based on the Earliest Deadline First (EDF) algorithm is born in the small context of the [[http://retis.sssup.it|Real-Time Systems (ReTiS) Lab of Scuola Superiore Sant'Anna]] and its Spin-Off company [[http://www.evidence.eu.com|Evidence Srl]]. |

| The original version of the patch was called SCHED_EDF and [[https://lkml.org/lkml/2009/9/22/186|presented to the Linux kernel community in 2009]].
