Virtualizing a hardware monotonic counter
Abstract:
Embodiments of an invention for virtualizing a hardware monotonic counter are disclosed. In one embodiment, an apparatus includes a hardware monotonic counter, virtualization logic, a first non-volatile storage location, and a second non-volatile storage location. The virtualization logic is to create a virtual monotonic counter from the hardware monotonic counter. The first non-volatile storage location is to store an indicator that the count of the hardware monotonic counter has changed. The second non-volatile storage location is to store an indicator that the count of the virtual monotonic counter has changed.
