Yin Fengwei 4579e57e7b hv: add gva check for the case gva is from instruction decode
For the instructions other than MOVS, one operand is register
and another one is memory which trigger EPT voilation. In this
case, there is one possibility that EPT voilation happens before
guest fault:
    the fault is triggered by related guest PTE access bit
    voilation (like write to a gva with R/W bit cleared in PTE).

So we do this kind of check and inject exception to guest
accordingly during instruction decoding phase.

Embedded-Hypervisor
###################

This open source embedded hypervisor defines a software architecture for
running multiple software subsystems managed securely on a consolidated
system (by means of a virtual machine manager), and defines a reference
framework Device Model implementation for devices emulation

This embedded hypervisor is type-1 reference hypervisor, running
directly on the system hardware. It can be used for building software
defined cockpit (SDC) or In-Vehicle Experience (IVE) solutions running
on Intel Architecture Apollo Lake platforms. As a reference
implementation, it provides the basis for embedded hypervisor vendors to
build solutions with an open source reference I/O mediation solution,
and provides auto makers a reference software stack for SDC usage.

This embedded hypervisor is able to support both Linux* and Android* as
a Guest OS, managed by the hypervisor, where applications can run.

This embedded hypervisor is a partitioning hypervisor reference stack,
also suitable for non-automotive IoT & embedded device solutions. It
will be addressing the gap that currently exists between datacenter
hypervisors, hard partitioning hypervisors, and select industrial
applications.  Extending the scope of this open source embedded
hypervisor relies on the involvement of community developers like you!
