Subject: [PATCH 00/14] sched: SCHED_DEADLINE v8
Date: Mon, 14 Oct 2013 12:43:32 +0200 [thread overview]
Message-ID: <1381747426-31334-1-git-send-email-juri.lelli@gmail.com> (raw)
Hello everyone,
here we go with a new version of the SCHED_DEADLINE patchset (v8). I know that
it has been a while since I released last version [1], but I thought not to
spam the mailing list with simple updates. Well... this IS basically an update
to 3.12-rc5, but it comes right before the next Kernel Summit and Real Time
Linux Workshop and, since I'll be present at both events, it is probably time
to fire-up the discussion again.
Moreover, interesting news:
- a better mechanism for coordinating mutually exclusive access to critical
sections is coming soon (we wrote a paper about it for RTLWS15 [2]);
- the patchset is now available in the 3.4 and 3.10 Yocto kernels [3] (thanks
a lot for this to Bruce Ashfield and Insop Song); even though it is hard to
say how many new users we got with this, we can say that having
SCHED_DEADLINE in Yocto provides availabily to OSVs like Wind River and
others;
- a european project has started (JUNIPER [4]) for which we will provide
kernel level support based on this patchset (and we will soon have a real
use case for it! yayyy! :)).
The development is taking place at:
https://github.com/jlelli/sched-deadline
branch: sched-dl-V8 (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 [4].
As usual, any kind of feedback is welcome and appreciated.
Thanks in advice and regards,
- Juri
