<div dir="ltr">Hello all,<br><br>Maybe you have read my mail in <a href="mailto:users@rtems.org">users@rtems.org</a> mailing list.<br>I make a new ticket in #2795 to replace #2722 with more detail information.<br>(<a href="https://devel.rtems.org/ticket/2795">https://devel.rtems.org/ticket/2795</a>)<br><br>This enhancement ticket aims at the overrun issue: When there are deadline misses, the postponed jobs that should be released are never released to the system. Moreover, the deadline of postponed jobs is shifted violating the strictly periodic release pattern.<br><br>I believe this ticket could enhance RTEMS to adapt more general task models for now and build up a basis for the future usage, e.g, soft real-time task, arbitrary deadline task model, mixed-criticality systems.<br><br>I have reviewed FreeRTOS and Litmus-RT to check their implementation as the references.<br>Litmus-RT has this feature and FreeRTOS only has the part of the release pattern alignment.<br><br>The detail of the work [1] will be presented in Workshop mixed-criticality 2016 along with RTSS'16 this year.<br><br>Please kindly consider my enhancement and let me know what I can do further.<br><br>Cheers,<br>Kuan-Hsun<br><br>[1] Chen et al, Overrun Handling for Mixed-Criticality Support in RTEMS, WMC'16, accepted.<div><br></div>-- <br><div class="gmail_signature"><div dir="ltr">M.Sc.
