ACRN v0.2 (Sep 2018)

We are pleased to announce the release of Project ACRN version 0.2.

ACRN is a flexible, lightweight reference hypervisor, built with real-time and safety-criticality in mind, optimized to streamline embedded development through an open source platform. Check out the 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, and documentation. You can either download this source code as a zip or tar.gz file (see the ACRN v0.2 GitHub release page or use Git clone and checkout commands:

git clone https://github.com/projectacrn/acrn-hypervisor
cd acrn-hypervisor
git checkout v0.2

The project’s online technical documentation is also tagged to correspond with a specific release: generated v0.2 documents can be found at https://projectacrn.github.io/0.2/. Documentation for the latest (master) branch is found at https://projectacrn.github.io/latest/.

Version 0.2 new features

VT-x, VT-d

Based on Intel VT-x virtualization technology, ACRN emulates a virtual CPU with core partition and simple schedule. VT-d provides hardware support for isolating and restricting device accesses to the owner of the partition managing the device. It allows assigning I/O devices to a VM, and extending the protection and isolation properties of VMs for I/O operations.

PIC/IOAPIC/MSI/MSI-X/PCI/LAPIC

ACRN hypervisor supports virtualized APIC-V/EPT/IOAPIC/LAPIC functionality.

Ethernet

ACRN hypervisor supports virtualized Ethernet functionality. Ethernet Mediator is executed in the Service OS and provides packet forwarding between the physical networking devices (Ethernet, Wi-Fi, etc.) and virtual devices in the Guest VMs(also called “User OS”). Virtual Ethernet device could be shared by Linux, Android, and Service OS guests for regular (i.e. non-AVB) traffic. All hypervisor para-virtualized I/O is implemented using the VirtIO specification Ethernet pass-through.

Storage (eMMC)

ACRN hypervisor supports virtualized non-volatile R/W storage for the Service OS and Guest OS instances, supporting VM private storage and/or storage shared between Guest OS instances.

USB (xDCI)

ACRN hypervisor supports virtualized assignment of all USB xHCI and/or xDCI controllers to a Guest OS from the platform.

USB Mediator (xHCI and DRD)

ACRN hypervisor supports a virtualized USB Mediator.

CSME

ACRN hypervisor supports a CSME to a single Linux, Android, or RTOS guest or the Service OS even when in a virtualized environment.

WiFi

ACRN hypervisor supports the passthrough assignment of the WiFi subsystem to the IVI, enables control of the WiFi as an in-vehicle hotspot for 3rd party devices, provides 3rd party device applications access to the vehicle, and provides access of 3rd party devices to the TCU provided connectivity.

IPU (MIPI-CS2, HDMI-in)

ACRN hypervisor supports passthrough IPU assignment to Service OS or guest OS, without sharing.

Bluetooth

ACRN hypervisor supports bluetooth controller passthrough to a single Guest OS (IVI).

GPU - Preemption

GPU Preemption is one typical automotive use case which requires the system to preempt GPU resources occupied by lower priority workloads. This is done to ensure performance of the most critical workload can be achieved. Three different schedulers for the GPU are involved: i915 UOS scheduler, Mediator GVT scheduler, and i915 SOS scheduler.

GPU - display surface sharing via Hyper DMA

Surface sharing is one typical automotive use case which requires that the SOS accesses an individual surface or a set of surfaces from the UOS without having to access the entire frame buffer of the UOS. Hyper DMA Buffer sharing extends the Linux DMA buffer sharing mechanism where one driver is able to share its pages with another driver within one domain.

S3

ACRN hypervisor supports S3 feature, partially enabled in LaaG.

Fixed Issues

  • 663 - Black screen displayed after booting SOS/UOS
  • 676 - Hypervisor and DM version numbers incorrect
  • 1126 - VPCI coding style and bugs fixes for partition mode
  • 1125 - VPCI coding style and bugs fixes found in integration testing for partition mode
  • 1101 - missing acrn_mngr.h
  • 1071 - hypervisor cannot boot on skylake i5-6500
  • 1003 - CPU: cpu info is not correct
  • 971 - acrncrashlog functions need to be enhance
  • 843 - ACRN boot failure
  • 721 - DM for IPU mediation
  • 707 - Issues found with instructions for using Ubuntu as SOS
  • 706 - Invisible mouse cursor in UOS
  • 424 - Clear Linux OS desktop GUI of SOS fails to launch

Known Issues

677 - SSD Disk ID not consistent between SOS/UOS
The SSD disk ID in the UOS is not the same as in the SOS when the SSD device is passed-through to the UOS (it should be). The ID is also changing after a reboot (it shouldn’t). Impact: There is no impact to functionality. Workaround: None. The issues will be fixed in the next release.
1268 - GPU hangs when running GfxBench Car Chase in SOS and UOS.
A “GPU HANG” log messages is printed in the dmesg log in SOS and UOS and is fails to load GfxBench Car Chase animation in HDMI and VGA monitors. Impact: Car Chase may stop running after the GPU hangs, but does not block other Gfx apps. Workaround: None. The issue will be fixed in the next release.
1270 - SOS and UOS play video but don’t display video animation output on monitor.
Video does not display in SOS and UOS. Animation is not displayed with the running timer. Impact: There is no video animation on monitor screen when playing video in SOS or UOS. Workaround: None. The issue will be fixed in the next release.
1319 - SD card pass-through: UOS can’t see SD card after UOS reboot.
SD card could not be found after UOS reboot in pass-through mode. Impact: There is no SD card after UOS reboot. Workaround: None. The issue will be fixed in the next release.
