摘要:
For one disclosed embodiment, a transition from a first state to a second, different state for at least a portion of a downstream device may be identified. The first and second states may correspond to different levels relating to activity for at least a portion of the downstream device. Data corresponding to a service latency may be transmitted to an upstream device in response to the identified transition for one or more upstream devices to manage power based at least in part on the service latency. Other embodiments are also disclosed.

摘要:
A method and apparatus for intelligent power management for low power link states. Some embodiments include methods, apparatuses, and systems for a device coupled to a controller via a link; a link power management engine to alter a power state of the link based on a transaction and some knowledge of future transactions between the device and the controller; and a memory or logic to store the link power management engine. In some embodiments, the memory stores information about at least one of the following: the power state of the link, the device buffering, the controller or device state or a history of transactions. In some embodiments, the device is a peripheral of a computer system. In some embodiments, the method may include transitioning the device to various link states. Other embodiments are described.
