Abstract: In one example, a system for a system management mode (SMM) privilege architecture includes a computing device comprising: a first portion of SMM instructions to set up a number of resources and implement a privilege architecture for the SMM of a computing device and a second portion of SMM instructions to execute a number of functions during the SMM of the computing device, wherein the privilege architecture assigns the first portion of SMM instructions to a first privilege level and assigns the second portion of SMM instructions to a second privilege level.
