In the hypervisor, VMCS fields include 16-bit fields,
32-bit fields, 64-bit fields and natural-width fields.
In the current implement, no exec_vmread32/exec_vmwrite32
is for accessing 32-bit fields. So there are many type
casting for the return value and parameters vmread/vmwrite
operations.
Create exec_vmread32 and exec_vmwrite32 functions to
access 32-bit fields in VMCS;
Update related variables type for vmread/vmwrite operations;
Update related caller according to VMCS fields size.
V1--V2:
This is new part of this patch serial to only
update 32 bit vmread/vmread opertions and related
caller.
V2-->V3:
Update related variables type in data structure
for exec_vmread32/exec_vmwrite32.
Rename temp variable 'low' into 'value' for
exec_vmread32;
V3-->V4:
Remove useless type conversion.

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!
