Abstract:
In one embodiment, the present invention includes a method for determining if an isolation driver is present and a processor supports virtualization, launching the isolation driver in a first privilege level different than a system privilege level and user privilege level, creating a 1:1 virtual mapping between a virtual address and a physical address, using the isolation driver, and controlling access to a memory page using the isolation driver. Other embodiments are described and claimed.
