Fei Jiang 4980b95d73 [acrn-dev] [PATCH] VMX: change PAT register default value 
This is workaround patch to resolve Disti performance issue.
In kernel 4.14, PAT is skipped to initialize if MTRR is not enabled,
while graphics driver need set WC to GGTT memory to accelerate memcpy,
if PAT is not initialized, default PAT register will treat UC- as
uncacheable, which will impact gfx performance. Change PAT default
register value to treat UC- as WC to workaroud this problem.

Revert me when PAT/MTRR strong correlation is removed in kernel.

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!
