ACRN v1.6 (Mar 2020)
####################

We are pleased to announce the release of ACRN version 1.6.

ACRN is a flexible, lightweight reference hypervisor that is built with
real-time and safety-criticality in mind. It is optimized to streamline
embedded development through an open source platform. Check out :ref:`introduction` for more information.
All project ACRN source code is maintained in the https://github.com/projectacrn/acrn-hypervisor
repository and includes folders for the ACRN hypervisor, the ACRN device
model, tools, and documentation. You can either download this source code as
a zip or tar.gz file (see the `ACRN v1.6 GitHub release page
<https://github.com/projectacrn/acrn-hypervisor/releases/tag/v1.6>`_)
or use Git clone and checkout commands::

   git clone https://github.com/projectacrn/acrn-hypervisor
   cd acrn-hypervisor
   git checkout v1.6

The project's online technical documentation is also tagged to correspond
with a specific release: generated v1.6 documents can be found at https://projectacrn.github.io/1.6/.
Documentation for the latest (master) branch is found at https://projectacrn.github.io/latest/.
ACRN v1.6 requires Clear Linux OS version 32680.

Version 1.6 Major Features
**************************

What's New in v1.6
==================
* Graphics passthrough support

  - The hypervisor and Service VMs support allowing passthrough graphics devices to target DM-launched guest VMs, based on GVT-d.

* SRIOV support

  - The ACRN hypervisor allows an SRIOV-capable PCI device's Physical Function (PF) to be allocated to the Service VM.

  - The ACRN hypervisor allows a SRIOV-capable PCI device's Virtual Functions (VFs) to be allocated to any VM.

  - The ACRN Service VM supports the SRIOV Ethernet device (through the PF driver), and ensures that the SRIOV VF device is able to be assigned (passthrough) to a post-launched VM (launched by ACRN-DM).

* CPU sharing enhancement -  Halt/Pause emulation

  - For a vCPU that uses the fairness CPU scheduler, the hypervisor supports yielding an idle vCPU (when it's running a 'HLT' or 'PAUSE' instruction).

* PCI Config space access emulation for passthrough devices in the hypervisor

  - The hypervisor provides the necessary emulation (such as config space) of the passthrough PCI device during runtime for a DM-launched VM. Such runtime emulation is DM-independent.

* PCI bridge emulation in hypervisor

Document Updates
================
Many new and updated `reference documents <https://projectacrn.github.io>`_ are available, including:

* :ref:`asa`
* :ref:`sriov_virtualization`
* :ref:`using_xenomai_as_uos`
* :ref:`split-device-model`
* :ref:`rdt_configuration`


We recommend that all developers upgrade to ACRN release v1.6.
