Abstract: In one embodiment, a processor includes an access logic to determine whether an access request from a virtual machine is to a device access page associated with a device of the processor and if so, to re-map the access request to a virtual device page in a system memory associated with the VM, based at least in part on information stored in a control register of the processor. Other embodiments are described and claimed.
