Patent ID: 8738950

Claim:
A first device, comprising: a link power management logic utilizing an enhanced link policy to cause a link, the link coupling the first device and a second device, to transition between a plurality of power management states including an active state, a first idle state, and a second idle state, wherein the link power management logic is to at least: transition the link from the active state to the first idle state at least when a first inactivity timer expires; transition the link from the first idle state to the second idle state at least when a second inactivity timer expires and the first device and the second device are not active in a data pattern including a series of transactions with periods of inactivity between transactions, wherein the link is to remain in the first idle state upon the expiration of the second inactivity timer if the first device and second device are in a period of inactivity between transactions of the data pattern; and transition the link from one of the first idle state and the second idle state to the active state when a pending data packet is to be transmitted on the link.
