[Xen-devel] [PATCH] [RFC] Credit2 scheduler prototype

[George Dunlap <George.Dunlap@xxxxxxxxxxxxx>]

I'm attaching patches for the rudimentary new credit2 scheduler which
I discussed at the Summit.  It's definitely still at a developmental
stage, but it's in a state where people should be able to contribute
now.

I've put up a wiki page to help coordinate development here:
 http://wiki.xensource.com/xenwiki/Credit2_Scheduler_Development

Some caveats:
* There is no inter-socket load balancing.  This is one of the work
items to be done.
* It works on my 2-core box, but deadlocks on my 4-core box; cause
still to be determined.

The wiki page lists a number of semi-independent lines of development
that people can take.  Let me know if you're interested in any of
them, and if you have any questions, and I can elaborate.

Keir (and everyone), I think at this point it would be a good idea to
start a credit2 development branch in ext/ so we can keep a revision
history.  Thoughts?
