Abstract: A method of re-mapping memory regions for firmware run-time services to a virtual address space of a kernel executed on a processor, includes the steps of selecting a re-mapping policy for re-mapping the memory regions for the firmware run-time services, creating a new mapping according to the selected re-mapping policy, and making a call to an application programming interface exposed by the firmware to apply the new map and re-map the memory regions for the firmware to the virtual address space of the kernel.

Abstract: Systems and techniques are described for power-aware scheduling. One of the techniques includes monitoring execution of a plurality of groups of software threads executing on a physical machine, wherein the physical machine comprises a physical hardware platform that includes a plurality of processor packages having a plurality of package power states, wherein the plurality of package power states includes an independent package power state; obtaining a respective independent power state measure for each of the processor packages, wherein the independent power state measure provides a measure of a percentage of time the processor package spends in the independent package power state; and adjusting an allocation of the plurality of groups of software threads across the plurality of processor packages based in part on the independent power state measures for the packages.
