Hello everyone,
SCHED_DEADLINE patchset v9, less than a month after last version [1]!
Changes w.r.t. v8:
- rebase on top of 3.12; - all comments from Peter Zijlstra and Ingo Molnar applied (thanks!): + auxiliary functions for UP/SMP cases + add a smp_rmb to match dl_set_overload smp_wmb + different clocks for deadlines and runtime need further study + amend the comment about yield_task_dl semantic + use an accessor to read the rq clock + clarify 06/14 changelog (why we want to specify periods != deadlines)
The development is taking place at: https://github.com/jlelli/sched-deadline
branch: sched-dl-V9-rebase (this patchset on top of tip/master).
Check the repositories frequently if you're interested, and feel free to e-mail me for any issue you run into.
Test applications: https://github.com/gbagnoli/rt-app https://github.com/jlelli/schedtool-dl
Development mailing list: linux-dl; you can subscribe from here: http://feanor.sssup.it/mailman/listinfo/linux-dl or via e-mail (send a message to linux-dl-request@retis.sssup.it with just the word `help' as subject or in the body to receive info).
The code was being jointly developed by ReTiS Lab (http://retis.sssup.it) and Evidence S.r.l (http://www.evidence.eu.com) in the context of the ACTORS EU-funded project (http://www.actors-project.eu) and the S(o)OS EU-funded project (http://www.soos-project.eu/). Development is now supported by the JUNIPER EU-funded project [2].
As usual, any kind of feedback is welcome and appreciated.
Thanks in advice and regards,
- Juri
