Integrated Dell Remote Access Controller 9 Attribute Registry

BIOS.ProcSettings.DynamicCoreAllocation (Read or Write)

Description

Logical Processor Idling (LPI) is a collaborative interface between platform and Operating System that helps to improve the energy efficiency of a system. This feature is required in those cases where customer has a need to go for power budgeting. It uses Operating Systems core parking algorithm and parks some of the logical processors in the system which in turn lets the corresponding processor cores transition into a lower power idle state. If LPI is getting used instead of throttling, better performances can be achieved when power budgeting is used. Setting to Disabled limits the OS capability to put the logical processors in idling state. Note: This feature is not supported if CPU Power Management is set to Maximum Performance.
