Re: [Xen-devel] [PATCH 0 of 5] Add credit2 scheduler (EXPERIMENTAL)

[George Dunlap <george.dunlap@xxxxxxxxxxxxx>]

Keir has checked the patches in, so if you wait a bit, they should show 
up on the public repository.
The tool patch is only necessary for adjusting the weight; if you're OK 
using the default weight, just adding "sched=credit2" on the xen 
command-line should be fine.
Don't forget that this isn't meant to perform well on multiple sockets 
yet. :-)
