An exemplary computing device includes a plurality of circuits and/or a plurality of in-situ monitors configured to generate outputs that indicate one or more operating conditions of the circuits. The computing device also includes a system management unit configured to detect a potentially faulty voltage-to-frequency ratio implemented by one of the circuits based at least in part on one or more of the outputs. The system management unit is also configured to modify the potentially faulty voltage-to-frequency ratio based at least in part on one or more of the outputs. Various other devices, systems, and methods are also disclosed.

The disclosed method includes detecting a stalled memory request, for a first level cache within a cache hierarchy of a processor, that includes an outstanding memory request associated with a second level cache within the cache hierarchy that is higher than the first level cache. The method further includes indicating, to the second level cache, that the first level cache is experiencing a starvation issue due to stalled memory requests to enable the second level cache to perform starvation-remediation actions. Various other methods, systems, and computer-readable media are also disclosed.
