1. A method to detect feedback control instability in thermal control, the method comprising:
for a set of dwell time intervals, wherein the dwell time intervals are associated with a range of periods of time from an initial period to a base period,
executing a workload that varies from minimum to maximum over the period of time on a computing device during the dwell time interval;
recording telemetry data from the computing device during execution of the workload;
incrementing the period towards a base period;
determining that either the base period is reached or a thermal inertia threshold is reached; and
analyzing the recorded telemetry data over the set of dwell time intervals to either (i) detect presence of a feedback control instability in thermal control for the computing device; or (ii) confirm feedback control stability in thermal control for the computing device.
