Abstract
Methods, apparatus, and systems for power management of clustered computing platforms. Firmware provided on each platform is loaded for operating system runtime availability. The firmware traps power change events corresponding to a change in a power state of a component or device associated with a platform, such as a processor or a peripheral device. In response to the power change event, the firmware sends corresponding data to a power arbiter using an out-of-band (OOB) communication network/channel. The power arbiter determines an appropriate reallocation of power consumption allotments for the various platforms under its control based on a power management policy. Updated power consumption allocation information is then sent to selected platforms via the OOB network/channel. Upon receipt of the updated allotments, corresponding registers and/or tables are updated on the platforms to effectuate a change in power consumption of one or more components/devices associated with the platform.
