/*
* \brief Utilities for implementing VMMs on Genode/NOVA
* \author Norman Feske
* \date 2013-08-20
*
* The VMM and the guest share the same PD. However, the guest's view on the PD
* is restricted to the guest-physical-to-VMM-local mappings installed by the
* VMM for the VCPU's EC.
*
* The guest memory is shadowed at the lower portion of the VMM's address
* space. If the guest (the VCPU EC) tries to access a page that has no mapping
* in the VMM's PD, NOVA does not generate a page-fault (which would be
* delivered to the pager of the VMM, i.e., core) but it produces a NPT
* virtualization event handled locally by the VMM. The NPT event handler is
* the '_svm_npt' function.
