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.
