Abstract

The present invention provides a method, apparatus, and system for invoking a reset process in response to a processor being individually reset. The reset processor operates within a platform in an isolated execution mode and is associated with an isolated area of memory. An initialization process is invoked for an initializing processor. The initialization process determines whether or not a cleanup flag is set. If the cleanup flag is set, the isolated area of memory is scrubbed. In one embodiment, when a last processor operating in the platform is reset, it is reset without clearing the cleanup flag. Subsequently, an initializing processor invokes the initialization process. The initialization process determines that the cleanup flag is set. The initialization process invokes the execution of a processor nub loader. If the cleanup flag is set, the processor nub loader scrubs the isolated area of memory and invokes a controlled close for the initializing processor. The controlled close clears the cleanup flag. The initializing processor then re-performs the initialization process. Upon the second iteration of the initialization process, with the cleanup flag not set, a new isolated area of memory is created for the initializing processor.
