ACRN v0.3 (Nov 2018)

We are pleased to announce the release of Project ACRN version 0.3.

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 Introduction to Project 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 v0.3 GitHub release page or use Git clone and checkout commands:

git clone https://github.com/projectacrn/acrn-hypervisor
cd acrn-hypervisor
git checkout v0.3

The project’s online technical documentation is also tagged to correspond with a specific release: generated v0.3 documents can be found at https://projectacrn.github.io/0.3/. Documentation for the latest (master) branch is found at https://projectacrn.github.io/latest/.

  • 1270 - SOS and UOS play video but don’t display video animation output on monitor.
  • 1339 - SOS failed to boot with SSD+NVMe boot devices on KBL NUC
  • 1432 - SOS failed boot

Known Issues

677 - SSD Disk ID is 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.
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.
1773 - USB Mediator: Can’t find all devices when multiple usb devices connected[Reproduce rate:60%]
After booting UOS with multiple USB devices plugged in, sometimes there are one or more devices cannot be discovered. The reproduce rate is ~60%. Impact: Cannot use multiple usb devices at same time. Workaround: Plug-out and plug-in the unrecognized device again.
1774 - UOS can’t stop by command: acrnctl stop [vm name] in SOS
After launching UOS in SOS by “acrnctl start” command, UOS VM failed to be stopped by “acrnctl stop” command. Impact: Can’t stop UOS in SOS. Workaround: None. The issue will be fixed in the next release.
1775 - [APL UP2]ACRN debugging tool - acrntrace cannot be used in SOS
There are no acrntrace devices “acrn_trace*” under SOS /dev. Impact: acrntrace cannot be used in SOS. Workaround: None. The issue will be fixed in the next release.
1776 - [APL UP2]ACRN debugging tool - acrnlog cannot be used in SOS
There are no acrnlog devices “acrn_hvlog*” under SOS /dev. Impact: acrnlog cannot be used in SOS. Workaround: None. The issue will be fixed in the next release.
1777 - After UOS plays video for several minutes, the UOS image will be stagnant
After UOS plays video for several minutes, the UOS image will be stagnant. Impact: UOS cannot play video image smoothly all the time. Workaround: None. The issues will be fixed in the next release.
1779 - gfxbench cannot run in SOS or UOS
Failed to run gfxbench in SOS or UOS. Impact: Cannot run gfxbench in SOS or UOS. Workaround: None. The issues will be fixed in the next release.
1780 - Some video formats cannot be played in SOS
There are several formats of videos that cannot be played in SOS: H265_10bits, VP8, VP9, VP9_10bits, H265.720p. Impact: Cannot play those formats of videos in SOS. Workaround: None. The issues will be fixed in the next release.
1782 - UOS failed to get IP address with the pass-through network card
After network card is pass-through to UOS, it fails to get IP address in UOS. Impact: Cannot use network in UOS. Workaround: None. The issues will be fixed in the next release.
1794 - After SOS boots up, there’s no output on SOS screen
After SOS boots up with both “desktop” and “soft-defined-cockpit” bundles installed or without any, there’s no output on SOS screen. Impact: Cannot access SOS. Workaround: Only install “desktop” bundle, then enable and start weston in Native Clear Linux, and then reboot to SOS. The issues will be fixed in the next release.
1795 - [KBL NUC] SOS fails to get IP address
On KBL NUC hardware platform, SOS fails to get IP address after SOS boot. Impact: Cannot use network in SOS. Workaround: None. The issues will be fixed in the next release.
1796 - APL NUC fails to reboot sometimes
After APL NUC boot to SOS, type “reboot” to reboot SOS, it fails to reboot sometimes. Impact: Cannot reboot SOS. Workaround: Power off and boot again. The issues will be fixed in the next release.
