摘要

PROBLEM TO BE SOLVED: To disclose a system and a method for allowing execution of a system management mode (SMM) code during secure operations in a microprocessor system.;SOLUTION: In one embodiment, a system management interruption (SMI) can be first directed to a handler in a secured virtual machine monitor (SVMM). Then, the SMI can be redirected to a SMM code located in a virtual machine (VM) which is under the security control of the SVMM. This redirection can be achieved by enabling reading from and writing onto the system management (SM) base register in the processor.;COPYRIGHT: (C)2012,JPO&INPIT
