Abstract: In a method for switching to a spare processor during runtime, a processing system determines that execution should be migrated off of an active processor. An operating system (OS) scheduler and at least one device are then paused, and the active processor is put into an idle state. State data from writable and substantially non-writable stores in the active processor is loaded into the spare processor. Interrupt routing table logic for the processing system is dynamically reprogrammed to direct external interrupts to the spare processor. The active processor may then be off-lined, and the device and OS scheduler may be unpaused or resumed. Threads may then be dispatched to the spare processor for execution. Other embodiments are described and claimed.
