    Abstract: Systems, methods, and devices are disclosed for mitigating voltage droop in a computing device. An example apparatus includes a plurality of threshold registers to store respective voltage droop thresholds, and an interface to receive a license grant message indicating a license mode for a processor core or domain. The license mode corresponds to a selected set of execution units in the processor core or domain. The apparatus also includes a voltage droop correction module to, based on the license mode indicated in the license grant message, select one of the voltage droop thresholds from the plurality of voltage droop registers, and compare a voltage droop in the processor core or domain with the selected voltage droop threshold. Based on the comparison, the apparatus triggers a voltage droop correction process.

    Abstract: In an embodiment, a processor includes a plurality of cores each to independently execute instructions, a power delivery logic coupled to the plurality of cores, and a power controller including a first logic to cause a first core to enter into a first low power state of an operating system power management scheme independently of the OS, during execution of at least one thread on the first core. Other embodiments are described and claimed.
