Patent number: 11054887Abstract: Systems, apparatuses, and methods for performing efficient power management for a multi-node computing system are disclosed. A computing system includes multiple nodes. When power down negotiation is distributed, negotiation for system-wide power down occurs within a lower level of a node hierarchy prior to negotiation for power down occurring at a higher level of the node hierarchy. When power down negotiation is centralized, a given node combines a state of its clients with indications received on its downstream link and sends an indication on an upstream link based on the combining. Only a root node sends power down requests.Type: GrantFiled: December 28, 2017Date of Patent: July 6, 2021Assignee: Advanced Micro Devices, Inc.Inventors: Benjamin Tsien, Greggory D. Donley, Bryan P.

Patent number: 11048523Abstract: An information handling system (IHS), baseboard management controller (BMC) and method provide for coordinating the BMC and the host processor subsystem to avoid conflicts between power operations by BMC and maintenance activities by the host processor subsystem. In response to determining that a power operation is requested for the host processor subsystem, a service processor of the BMC determining whether a planned power operation (PPO) software sensor contains information indicating that the host processor subsystem is executing a critical operation utility. In response to determining that the host processor subsystem is not executing the critical operation utility, service processor updates/modifies information contained in the PPO software sensor to indicate that a power operation is scheduled.
