[PATCH] Accurate vcpu weighting for credit scheduler
Hi,
This patch intends to accurate vcpu weighting
for CPU intensive job.
The reason of this problem is that
vcpu round-robin queue blocks large weight vcpus
by small weight vcpus.
For example, we assume following case on 2pcpu environment.
(with 4domains (each domain has 2vcpus))
dom1 vcpu0,1 w128 credit 4
dom2 vcpu0,1 w128 credit 4
dom3 vcpu0,1 w256 credit 8
dom4 vcpu0,1 w512 credit 15

Power aware credit scheduler

power saving ability with negligible performance impact, following
areas may be tweaked and listed here for comments first.
Goal is not to silly save power with sacrifice of performance, e.g.
we don''t want to prevent migration when there''re free cpus with
some pending runqueues. But when free computing power is
