•
Memory subsystem power limiting – The Intel ME/Intel NM monitors memory power consumption.
Memory power consumption is estimated using average bandwidth utilization information.
•
Processor power monitoring and limiting – The Intel ME/Intel NM monitors processor or socket
power consumption and holds average power over duration. It can be queried to return actual power
at any given instant. The monitoring process of the Intel ME is used to limit the processor power
consumption through processor P-states and dynamic core allocation.
•
Core allocation at boot time – Restrict the number of cores for OS/VMM use by limiting how many
cores are active at boot time. After the cores are turned off, the CPU limits how many working cores
are visible to the 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 runtime, after booting. An external agent can dynamically use or not
use cores in the processor subsystem by requesting Intel ME/Intel NM to control them, specifying the
number of cores to use or not use.
