Abstract: A system and method is disclosed for managing the access to GPIO ports that are coupled to input pins of devices in the computer system. Access commands directed to a GPIO port are monitored. When an access command is detected, an interrupt is issued and an interrupt handler determines if the access command is authorized. If the command is authorized, the interrupt handler completes the access command and returns control to the software program that issued the access command. If the command is not authorized, the command is prevented from reaching the GPIO and the access attempt is logged. The GPIO ports that are monitored may be those GPIO ports that are coupled to an input or enable pin of a sensitive hardware component within the computer system.

Abstract: A method for processing a system management interrupt (SMI) in a multi-processor information handling system including a boot processor and one or more application processors is provided. An SMI is generated by a particular application processor. A swap function is initiated, causing save state data associated with the particular application processor to be communicated to a boot processor SMI handler associated with the boot processor. The boot processor executes the boot processor SMI handler to process the SMI, the boot processor SMI handler using at least the save state data communicated to the boot processor by the swap function to process the SMI.
