ABSTRACT:
A system comprises a processor module that supports lockstep mode of operation. The system further comprises non-volatile data storage having stored thereto configuration information specifying whether the processor module is desired to operate in lockstep mode. A method comprises storing configuration information to non-volatile data storage of a system, wherein the configuration information specifies whether lockstep mode of operation is desired to be enabled or disabled for a processor module of the system. The method further comprises causing, by the system, the processor module to have its lockstep mode enabled or disabled as specified by the configuration information.
