ACRN v2.4 (Mar 2021) - DRAFT
|
|
############################
|
|
|
|
We are pleased to announce the release of the Project ACRN
|
|
hypervisor version 2.4.
|
|
|
|
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 the
|
|
:ref:`introduction` 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 v2.4 GitHub release page
|
|
<https://github.com/projectacrn/acrn-hypervisor/releases/tag/v2.4>`_) or
|
|
use Git clone and checkout commands::
|
|
|
|
git clone https://github.com/projectacrn/acrn-hypervisor
|
|
cd acrn-hypervisor
|
|
git checkout v2.4
|
|
|
|
The project's online technical documentation is also tagged to
|
|
correspond with a specific release: generated v2.4 documents can be
|
|
found at https://projectacrn.github.io/2.4/. Documentation for the
|
|
latest under-development branch is found at
|
|
https://projectacrn.github.io/latest/.
|
|
|
|
ACRN v2.4 requires Ubuntu 18.04. Follow the instructions in the
|
|
:ref:`rt_industry_ubuntu_setup` to get started with ACRN.

What's New in v2.4
|
|
******************
|
|
|
|
ACRN Configuration and Build
|
|
============================
|
|
|
|
[Add a short description of the changes to the ACRN configuration and build
|
|
process that no longer uses Kconfig and relies on XML files, and refer them to
|
|
the updated building from source and configuration options documents]
|
|
|
|

|
Because we dropped deprivileged boot mode support (in v2.3), we also
|
|
switched our Service VM of choice away from Clear Linux and have
|
|
removed Clear Linux-specific tutorials. Deleted documents are still
|
|
available in the `version-specific v2.1 documentation
|
|
<https://projectacrn.github.io/v2.1/>`_.
