摘要:
Apparatuses and methods for steering SMM code region accesses are disclosed. In one embodiment, an apparatus includes a status indicator, a base storage location, and an abort storage location. The status indicator is to indicate whether the apparatus is operating in SMM. The base storage location is to store a base address and the abort storage location is to store an abort address. The base address is to specify a first memory address region at which SMM code is to be accessed. The abort address is to specify a second memory address region to which accesses to the first memory address region are to be steered if the apparatus is not operating in SMM.
