Deadline scheduler

1st: I can't post a new topic in the "Try this!" section! The post new topic-link isn't there

There's a new scheduler http://www.evidence.eu.com/content/view/313/390/ called SCHED_DEADLINE, seems interesting! Might bring more low latency interactivity to the Linux desktop?

Anyone care to play with this?

Download and usage

A public git repository is available at the following address:
git clone git://gitorious.org/sched_deadline/linux-deadline.git
Information about download and usage is available here http://gitorious.org/sched_deadline/pages/Home .

Isn't deadline scheduler already in the kernel source?

@ forum: Ah okay, didn't notice that.

There is a deadline IO scheduler in the kernel, but it's not the same thing as this deadline cpu(?) scheduler afaik.

Reminds me of Con's (r)SD scheduler.

Re: Deadline scheduler

the algorythm logic seems to be the same, Con's is Round Robin algorythm and this one goes bu the name Earliest Deadline First scheduling, wich, by the name seems to do the same. just my guess.

Edit:
ok forget it, round robin is based on a timer and Earliest Deadline First is switches to a process closest to its deadline.
