Abstract:
Aspects of enhanced recovery mechanisms are described. A predetermined operating parameter for a power rail is set at the outset of system start. Afterwards, a processor is released to start with a power management circuit. In turn, the power management circuit receives a default operating parameter for the power rail from the processor, and stores the default operating parameter. The power management circuit also receives a runtime operating parameter for the power rail from the processor and modifies the operating parameter for the power rail according to the runtime operating parameter. If an error condition in the processor is encountered, the power management circuit may modify the operating parameter for the power rail according to the default operating parameter in response to a reset control signal from the processor. Use of the default operating parameter for the power rail may assist the processor to recover from the error condition.
