Abstract: A system detects a powerdown event, such as a power loss event, and performs a flush of volatile memory to persistent memory during a powerdown sequence. The system includes an energy backup device to power the system during the powerdown sequence. The system is configurable with optional settings that configure the powerdown sequence specific to a type of the energy backup device.

Abstract: A method and apparatus for dynamic power limit sharing among the modules in the platform. In one embodiment of the invention, the platform comprises a processor and memory modules. By expanding the power domain to include the processor and the memory modules, dynamic sharing of the power budget of the platform between the processor and the memory modules is enabled. For low-bandwidth workloads, the dynamic sharing of the power budget offers significant opportunity for the processor to increase its frequency by using the headroom in the memory power and vice versa. This enables higher peak performance for the same total platform power budget in one embodiment of the invention.

Abstract: Hierarchical Power Management (HPM) architecture considers the limits of scaling on a power management controller, the autonomy at each die, and provides a unified view of the package to a platform. At a simplest level, HPM architecture has a supervisor and one or more supervisee power management units (PMUs) that communicate via at least two different communication fabrics. Each PMU can behave as a supervisor for a number of supervisee PMUs in a particular domain. HPM addresses these needs for products that comprise a collection of dice with varying levels of power and thermal management capabilities and needs. HPM serves as a unified mechanism than can span collection of dice of varying capability and function, which together form a traditional system-on-chip (SoC). HPM provides a basis for managing power and thermals across a diverse set of dice.

Abstract: Methods and apparatus for balancing power between discrete components, such as processing units (e.g., CPUs) and accelerators in a compute node or platform. Power consumption of the compute platform is monitored to detect for conditions under which a threshold (e.g., power supply capacity threshold) is exceeded. In response, the operating frequencies of a processing unit and/or other platform components such as accelerators, are adjusted to reduce the power consumption of the platform to return below the threshold. Power limit biasing hints (scaling weights) are provided to platform components, along with a power violation index, which are used to adjust the operating frequencies of the platform components. Optionally, a processing unit can calculate the power violation index and the scaling weights and directly control the frequencies of itself and platform components. Embodiments of multi-socket platforms are also provided.

Abstract: A processing device includes a plurality of processing cores, a control register, associated with a first processing core of the plurality of processing cores, to store a first base clock frequency value at which the first processing core is to run, and a power management circuit to receive a base clock frequency request comprising a second base clock frequency value, store the second base clock frequency value in the control register to cause the first processing core to run at the second base clock frequency value, and expose the second base clock frequency value on a hardware interface associated with the power management circuit.
