ACRN v1.1 (June 2019)
#####################

We are pleased to announce the release of ACRN version 1.1.

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 :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 v1.1 GitHub release page
<https://github.com/projectacrn/acrn-hypervisor/releases/tag/v1.1>`_)
or use Git clone and checkout commands::

   git clone https://github.com/projectacrn/acrn-hypervisor
   cd acrn-hypervisor
   git checkout v1.1

The project's online technical documentation is also tagged to correspond
with a specific release: generated v1.1 documents can be found at https://projectacrn.github.io/1.1/.
Documentation for the latest (master) branch is found at https://projectacrn.github.io/latest/.
ACRN v1.1 requires Clear Linux* OS version 29970 or newer. Please follow the
instructions in the :ref:`getting-started-apl-nuc`.

Version 1.1 major features
**************************

Hybrid Mode Introduced
======================
In hybrid mode, a Zephyr OS is launched by the hypervisor even before the Service OS is
launched (pre-launched), with dedicated resources to achieve highest level of isolation.
This is designed to meet the needs of a FuSa certifiable safety OS.

Support for new guest Operating Systems
=======================================
* The `Zephyr RTOS <https://zephyrproject.org>`_ can be a pre-launched Safety OS in hybrid mode.
  It can also be a post-launched (launched by Service OS, not the hypervisor) as a guest OS.
* VxWorks as a post-launched RTOS for industrial usages.
* Windows as a post-launched OS

Document updates
================
We have many `reference documents available <https://projectacrn.github.io>`_, including:

* :ref:`Update: Using PREEMPT_RT-Linux for real-time UOS <rt_linux_setup>`
* :ref:`Zephyr RTOS as Guest OS <using_zephyr_as_uos>`

Known Issues
************

:acrn-issue:`1773` - USB Mediator: Can't find all devices when multiple USB devices connected
   After booting UOS with multiple USB devices plugged in,
   there's a 60% chance that one or more devices are not discovered.

   **Impact:** Cannot use multiple USB devices at same time.

   **Workaround:** Unplug and plug-in the unrecognized device after booting.

-----

:acrn-issue:`1991` - Input not accepted in UART Console for corner case
   Input is useless in UART Console for a corner case, demonstrated with these steps:

   1) Boot to SOS
   2) ssh into the SOS.
   3) use ``./launch_uos.sh`` to boot UOS.
   4) On the host, use ``minicom -D /dev/ttyUSB0``.
   5) Use ``sos_console 0`` to launch SOS.

   **Impact:** Fails to use UART for input.

   **Workaround:** Enter other keys before typing :kbd:`Enter`.

-----

:acrn-issue:`2267` - [APLUP2][LaaG] LaaG can't detect 4k monitor
   After launching UOS on APL UP2 , 4k monitor cannot be detected.

   **Impact:** UOS can't display on a 4k monitor.

   **Workaround:** Use a monitor with less than 4k resolution.

-----

:acrn-issue:`2279` - [APLNUC] After exiting UOS, SOS can't use USB keyboard and mouse
   After exiting UOS with mediator Usb_KeyBoard and Mouse, SOS cannot use the USB keyboard and mouse.

   These steps reproduce the issue:

   1) Insert USB keyboard and mouse in standard A port (USB3.0 port)
   2) Boot UOS by sharing the USB keyboard and mouse in cmd line:

      ``-s n,xhci,1-1:1-2:1-3:1-4:2-1:2-2:2-3:2-4 \``

   3) UOS access USB keyboard and mouse.
   4) Exit UOS.
   5) SOS tries to access USB keyboard and mouse, and fails.

   **Impact:** SOS cannot use USB keyboard and mouse in such case.

   **Workaround:** Unplug and plug-in the USB keyboard and mouse after exiting UOS.

-----

:acrn-issue:`2753` - UOS cannot resume after suspend by pressing power key
   UOS cannot resume after suspend by pressing power key

   **Impact:** UOS may failed to resume after suspend by pressing the power key.

   **Workaround:** None

-----

:acrn-issue:`2974` - Launching Zephyr RTOS as a real-time UOS takes too long
   Launching Zephyr RTOS as a real-time UOS takes too long

   These steps reproduce the issue:

   1) Build Zephyr image by follow the `guide
      <https://projectacrn.github.io/latest/tutorials/using_zephyr_as_uos.html?highlight=zephyr>`_.
   2) Copy the "Zephyr.img", "OVMF.fd" and "launch_zephyr.sh" to NUC.
   3) Execute the launch_zephyr.sh script.

   This is not reproducible with the stock ``launch_zephyr.sh`` script in our repo,
   it only happens when trying to launch an RTVM.

   **Impact:** Launching Zephyr RTOS as a real-time UOS takes too long

   **Workaround:** A different version of Grub is known to work correctly

-----

:acrn-issue:`3268` - dm: add virtio-rnd device to command line
   LaaG's network is unreachable with UOS kernel

   These steps reproduce the issue:

   1) Download Clear Linux OS
   2) Decompress Clear Linux
   3) Replace above ``kvm.img`` with default kernel in UOS
   4) Launch UOS
   5) Try to ping UOS from another host.
   6) UOS network is unreachable.

   **Impact:** LaaG's network is unreachable with UOS kernel

   **Workaround:** Add ``-s 7,virtio-rnd \`` to the launch_uos.sh script

-----

:acrn-issue:`3280` - AcrnGT holding forcewake lock causes high CPU usage in gvt workload thread.
   The i915 forcewake mechanism is to keep the GPU from its low power state, in
   order to access some specific registers. However, in the path of GVT-g scheduler submission,
   there's no need to acquire the i915 forcewake.

   **Impact:** AcrnGT holding forcewake lock cause high cpu usage gvt workload thread

   **Workaround:** None

-----

:acrn-issue:`3279` - AcrnGT causes display flicker in some situations.
   In current scaler ownership assignment logic, there's an issue that when SOS disables a plane,
   it will disable corresponding plane scalers; however, there's no scaler ownership checking there.
   So the scalers owned by UOS may be disabled by SOS by accident.  

   **Impact:** AcrnGT causes display flicker in some situations

   **Workaround:** None

-----
