Abstract

See full text

Methods and apparatus for seamless SMM (System Management Mode) global driver update base on SMM Root-of-Trust. Mechanisms are provided to load and replace SMM drivers at runtime in a secure manner, without requiring an SMM firmware update and platform reset. SMM code is executed by BIOS during boot in a hidden area of memory called SMRAM space. Seamless update using an SMM Global Driver Update provides a method to load and replace all SMM drivers (including SMM infrastructure) on an already shipped platform production for purposes such as bug fixes. The principles and teachings may also be applied to update other types of secure execution mode code in addition to SMM code.
