20100191936 | Method and system for operating-system-independent power management using performance verifications - Systems and methods are disclosed for power management in information handling systems using processor performance data to validate changes to processor performance states. Processor utilization data and processor performance data is obtained during system operation. The processor utilization data is analyzed to determine a desired performance state for the processor. Before setting the actual performance state of the processor to this desired performance state, however, processor performance data is analyzed to determine if prior changes to the performance state have been effective. The performance state of the processor is then changed are maintained based upon this additional performance verification analysis. | 07-29-2010 |
20100306768 | Methods for Managing Performance States in an Information Handling System - An information handling system (IHS) is disclosed wherein the system includes a processor associated with at least one performance state (P-state), and a memory in communication with the processor. The memory is operable to store a virtualization software and a basic input/out system (BIOS). The BIOS is configured to report a parameter of the P-state to the virtualization software. In addition, the BIOS is configured to transition the processor into a desired P-state. A method for managing performance states in an information handling system (IHS) is further disclosed wherein the method includes providing a basic input/output system (BIOS) in communication with a processor, the processor associated with an at least one performance state (P-state) and reporting a parameter of the at least one P-state to a virtualization software via the BIOS. The method further includes transitioning the processor to a desired P-state via the BIOS. | 12-02-2010 |

20130318371 | SYSTEMS AND METHODS FOR DYNAMIC POWER ALLOCATION IN AN INFORMATION HANDLING SYSTEM ENVIRONMENT - Systems and methods are disclosed that may be implemented to dynamically allocate relative power consumption between a group of multiple information handling system nodes that share a common (e.g., capacity-limited) power supply or source of power. The relative power consumption of the multiple information handling system nodes may be adjusted based on real time power consumption of each of the individual information handling system nodes, as well as the need for additional power by one or more of the individual information handling system nodes. A group of multiple information handling system nodes may dynamically communicate power usage characteristics in a distributed manner between themselves to implement a peer-to-peer acknowledgement architecture, or alternatively may communicate power usage characteristics to a centralized power manager. | 11-28-2013 |
