Jian Jun Chen dc77ef9e52 hv: ivshmem: map SHM BAR with PAT ignored 
ACRN does not support the variable range vMTRR. The default
memory type of vMTRR is UC. With this vMTRR emulation guest VM
such as Linux refuses to map the MMIO address space as WB. In
order to get better performance SHM BAR of ivshmem is mapped
with PAT ignored and memory type of SHM BAR is fixed to WB.

ACRN Hypervisor
###############

The open source `Project ACRN`_ defines a device hypervisor reference stack and
an architecture for running multiple software subsystems, managed securely, on
a consolidated system by means of a virtual machine manager. It also defines a
reference framework implementation for virtual device emulation, called the
"ACRN Device Model".

The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on
the bare-metal hardware, and is suitable for a variety of IoT and embedded
device solutions. The ACRN hypervisor addresses the gap that currently exists
between datacenter hypervisors, and hard partitioning hypervisors. The ACRN
hypervisor architecture partitions the system into different functional
domains, with carefully selected guest OS sharing optimizations for IoT and
embedded devices.

You can find out more about Project ACRN on the `Project ACRN documentation`_
website.
