  • Publication number: 20240085972
    Abstract: Embodiments described herein may include apparatus, systems, techniques or processes that are directed to chiplet state aware and dynamic prioritization of voltage regulator event indication handling. An intelligent arbiter notifies chiplets of VR events in a dynamic priority scheme that considers multiple factors such as chiplet state (for example, active, sleep, deep sleep, and the like), chiplet power consumption and time frame for transitioning to an active state, outstanding VR requests, chiplet latency sensitivity and the like in its prioritization of chiplet notifications. As chiplet states themselves are dynamic with a chiplet transitioning between multiple states during operation, the intelligent arbiter may also utilize a dynamic prioritization scheme to maximize efficiency and minimize power consumption.

  • Publication number: 20220197367
    Abstract: A hardware and software coordinated processor power state policy (e.g., policy for C-state) that delivers optimal power state selection by taking in to account the performance and/or responsiveness needs of thread expected to be scheduled on the core entering idle, to achieve improved IPC and performance for cores running user critical tasks. The scheme provides the ability to deliver responsiveness gains for important and/or user-critical threads running on a system-on-chip. A power management controller coupled to the plurality of processing cores, wherein the power management controller receives a hint from an operating system indicative of a bias towards a power state or performance state for at least one of the processing cores of the plurality of processing cores based on a priority of a thread in context switch.
