are visible to BIOS and OS/VMM. The cores that are turned off cannot be turned on dynamically after
the OS has started. It can be changed only at the next system reboot.
Core allocation at run-time: This particular use case provides a higher level processor power control
mechanism to a user at run-time, after booting. An external agent can dynamically use or not use cores
in the processor subsystem by requesting ME/NM to control them, specifying the number of cores to
use or not use.

Hardware Requirements
NM is supported only on platforms that have the NM FW functionality loaded and enabled on the Management
Engine (ME) in the SSB and that have a BMC present to support the external LAN interface to the ME. NM
power limiting features requires a means for the ME to monitor input power consumption for the platform. This
capability is generally provided by means of PMBus*-compliant power supplies although an alternative model
using a simpler SMBus* power monitoring device is possible (there is potential loss in accuracy and
responsiveness using non-PMBus* devices). The NM SmaRT/CLST feature does specifically require PMBus*-
compliant power supplies as well as additional hardware on the baseboard.
