Fei Li 65454730de hv:io: wrap mmio read/write When guest traps and wants to access a mmio region, the ACRN hypervisor doesn't know the mmio size the guest wants to access until the trap happens. In this case, ACRN should switch the mmio size and then call mmio_read8/16/32/64 or mmio_write8/16/32/64 in each trap place. This patch wrap the mmio read/write with a parameter to assign the mmio size. Tracked-On: #8255 Signed-off-by: Fei Li <fei1.li@intel.com>		2022-10-26 01:02:20 +08:00

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.
