ACRN v1.2 (Aug 2019)
####################

We are pleased to announce the release of ACRN version 1.2.

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 :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 v1.2 GitHub release page
<https://github.com/projectacrn/acrn-hypervisor/releases/tag/v1.2>`_)
or use Git clone and checkout commands::

   git clone https://github.com/projectacrn/acrn-hypervisor
   cd acrn-hypervisor
   git checkout v1.2

The project's online technical documentation is also tagged to correspond
with a specific release: generated v1.2 documents can be found at https://projectacrn.github.io/1.2/.
Documentation for the latest (master) branch is found at https://projectacrn.github.io/latest/.
ACRN v1.2 requires Clear Linux* OS version 30690 or newer. Please follow the
instructions in the :ref:`getting-started-apl-nuc`.

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

:acrn-issue:`3465` - HV: reinit pbar base if a device reset is detected
   When a passthru pci device is reset, its physical bar base address may be reset to 0,
   with vpci bar emulation, vpci needs to reinit the physical bar base address to a
   valid address if a device reset is detected.

   **Impact:** Fail to launch Clear Linux Preempt_RT VM with ``reset`` passthru parameter

   **Workaround:** Issue resolved on ACRN tag: ``acrn-2019w33.1-140000p``

-----

:acrn-issue:`3520` - bundle of "VGPU unconformance guest" messages observed for "gvt" in SOS console while using UOS
   After the need_force_wake is not removed in course of submitting VGPU workload,
   it will print a bundle of below messages while the User VM is started.

   | gvt: vgpu1 unconformance guest detected
   | gvt: vgpu1 unconformance mmio 0x2098:0xffffffff,0x0

   **Impact:** Messy and repetitive output from the monitor

   **Workaround:** Need to rebuild and apply the latest Service VM kernel from the ``acrn-kernel`` source code.

-----

:acrn-issue:`3533` - NUC hang while repeating the cold boot
   NUC will hang while repeating cold boot operation.

   1) Before begin coldboot, enable no passwd ssh for SOS and RTVM.
   #) Boot up Service VM
   #) Boot up Zephyr guest with UUID "d2795438-25d6-11e8-864e-cb7a18b34643"
   #) Boot up RTVM with UUID "495ae2e5-2603-4d64-af76-d4bc5a8ec0e5"
   #) Reboot RTVM and then will restart the whole system
   #) After Service VM boot up, return to step 3

   **Impact:** Cold boot operation is not stable for NUC platform

   **Workaround:** Need to rebuild and apply the latest Service VM kernel from the ``acrn-kernel`` source code.

-----

:acrn-issue:`3576` - Expand default memory from 2G to 4G for WaaG

   **Impact:** More memory size is required from Windows VM

   **Workaround:** Issue resolved on ACRN tag: ``acrn-2019w33.1-140000p``

-----

:acrn-issue:`3609` - Sometimes fail to boot os while repeating the cold boot operation

   **Workaround:** Please refer the PR information in this git issue

-----

:acrn-issue:`3610` - LaaG hang while run some workloads loop with zephyr idle

   **Workaround:** Revert commit ``bbb891728d82834ec450f6a61792f715f4ec3013`` from the kernel

-----

:acrn-issue:`3611` - OVMF launch UOS fail for Hybrid and industry scenario

   **Workaround:** Please refer the PR information in this git issue
