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 What is ACRN 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) 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 are available, including:

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