    摘要: In at least one embodiment described herein, an apparatus is provided that can include means for communicating a latency tolerance value for a device connected to a platform from a software latency register if a software latency tolerance register mode is active. The apparatus may also include means for communicating the latency tolerance value from a hardware latency register if a host controller is active. The latency tolerance value can be sent to a power management controller. More specific examples can include means for communicating a latency tolerance value from the software latency register if the software latency tolerance register mode is not active and the host controller is not active. The apparatus can also include means for mapping a resource space in the software latency register for the device using a BIOS/platform driver. The mapping can be achieved using an advanced configuration and power interface device description.

    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.
