Abstract

Techniques for firmware providing a simulated system management mode (SMM) while being executed by a non-x86 platform, such as an ARM platform. In response to receiving a service call from an OS interface driver, the firmware may determine a requested service identified by the service call. Thereafter, the firmware may identify an appropriate service handler to perform the requested service. After the appropriate service handler performs the requested service, the appropriate service handler notifies the OS interface driver. Since the SMM is emulated by the firmware, the firmware may execute on an x86 platform or a non-x86 platform, such as an ARM platform.
