 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 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 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 and Fabio Checconi. Claudio Scordino has been in charge of the initial coordination,​ supporting and project advertisement. Johan Eker from Ericsson ​has been in charge of coordination ​and supporting ​within ​the ACTORS ​project. 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 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 and Fabio Checconi.
