Abstract
Approaches that allow the context of an SMI task to be saved between SMIs. Upon entering an SMI handler for a task, a new task context stack is created. Thereafter, the SMI handler uses the task context, leaving the original stack unchanged. When the time limit for a single SMI is almost reached, the CPU is directed back to the original stack, and the task context stack persists in memory and retains the context of the task in hand. The soft SMI exits with an indication to signify that a new SMI should be invoked to continue processing. The entity that caused the first soft SMI then invokes another, passing in an indication to signify that this is a continuation of the prior task. On entering the SMI handler, the handler notes the request for continuation, switches to the saved task context stack and continues processing where it left off.
