ADAPTIVE LOW-POWER LINK-STATE ENTRY POLICY FOR ACTIVE INTERCONNECT LINK POWER MANAGEMENT

摘要

Methods and apparatus for implementing active interconnect link power management using an adaptive low-power link-state entry policy. The power state of an interconnect link or fabric is changed in response to applicable conditions determined by low-power link-state entry policy logic in view of runtime traffic on the interconnect link or fabric. The low-power link-state policy logic may be configured to include consideration of operating system input and Quality of Service (QoS) requirements for applications and devices employing the link or fabric, and device latency tolerance requirements.
