Abstract
According to one embodiment, a computer system includes a Central Processing Unit (CPU), a hub agent and a hub interface coupled to the first hub agent. The computer system transitions from a first power state to a second power state upon the CPU determining that no requests are pending to access the first hub interface.

A method of reducing power of a computer system including a hub interface architecture, the method comprising:
- operating in a first power state;
- and
- transitioning to a second power state upon detecting that no requests are pending to access a first hub interface.
A computer system comprising:
- a central processing unit (CPU);
- a first hub agent;
- and
- a first hub interface coupled to the first hub agent, wherein the computer system transitions from a first power state to a second power state upon the CPU determining that no requests are pending to access the first hub interface.

A system comprising:
- a first hub agent;
- a point to point interface coupled to the first hub agent;
- and
- a second hub agent coupled to the point to point interface, wherein the first and second agents transition from a first power state to a second power state upon detecting that no requests are pending on the point to point interface.
