Remove the Power Management ('pm') parameters from the sample launch scripts,
and update the comments, At most one VM is allowed to use "--pm_notify_channel uart"
at a time, since only one socket connection to SOS life_mngr is allowed.
Remove it by default and allow user to add on demand

|
|
|
#. Starting with the ACRN v2.2 release, we use the ``iasl`` tool to
|
|
compile an offline ACPI binary for pre-launched VMs while building ACRN,
|
|
so we need to install the ``iasl`` tool in the ACRN build environment.
|
|
|
|
Follow these steps to install ``iasl`` (and its dependencies) and
|
|
then update the ``iasl`` binary with a newer version not available
|
|
in Ubuntu 18.04:
|
|
|
|
.. code-block:: none
|
|
|
|
$ cd /home/acrn/work
|
|
$ wget https://acpica.org/sites/acpica/files/acpica-unix-20210105.tar.gz
|
|
$ tar zxvf acpica-unix-20210105.tar.gz
|
|
$ cd acpica-unix-20210105
|
|
$ make clean && make iasl
|
|
$ sudo cp ./generate/unix/bin/iasl /usr/sbin/
|
|
|
|
#. Get the ACRN source code:
|
|
|
|
.. code-block:: none
|
|
|
|
$ cd /home/acrn/work
|
|
$ git clone https://github.com/projectacrn/acrn-hypervisor
|
|
$ cd acrn-hypervisor
|
|
|
|
#. Switch to the v2.4 version:
|
|
|
|
.. code-block:: none
|
|
|
|
$ git checkout v2.4
|
|
|
|
#. Build ACRN:
|
|
|
|
.. code-block:: none
|
|
|
|
$ make BOARD=whl-ipc-i7 SCENARIO=industry
|
|
$ sudo make install
|
|
$ sudo mkdir -p /boot/acrn
|
|
$ sudo cp build/hypervisor/acrn.bin /boot/acrn/
|
|
|
|
Build and Install the ACRN Kernel
|
|
=================================
|
|
|
|
#. Build the Service VM kernel from the ACRN repo:
|
|
|
|
.. code-block:: none
|
|
|
|
$ cd /home/acrn/work/
|
|
$ git clone https://github.com/projectacrn/acrn-kernel
|
|
$ cd acrn-kernel
|
|
|
|
#. Switch to the 5.4 kernel:
|
|
|
|
.. code-block:: none
|
|
|
|
$ git checkout v2.4
|
|
$ cp kernel_config_uefi_sos .config
|
|
$ make olddefconfig
|
|
$ make all
|
|
|
|
Install the Service VM Kernel and Modules
|
|
=========================================
|
|
|
|
.. code-block:: none
|
|
|
|
$ sudo make modules_install
|
|
$ sudo cp arch/x86/boot/bzImage /boot/bzImage
|
|
|
|
Update Grub for the Ubuntu Service VM
|
|
=====================================
|
|
|
|
#. Update the ``/etc/grub.d/40_custom`` file as shown below.
|
|
|
|
.. note::
|
|
Enter the command line for the kernel in ``/etc/grub.d/40_custom`` as
|
|
a single line and not as multiple lines. Otherwise, the kernel will
|
|
fail to boot.
|
|
|
|
.. code-block:: none
|
|
|
|
menuentry "ACRN Multiboot Ubuntu Service VM" --id ubuntu-service-vm {
|
|
load_video
|
|
insmod gzio
|
|
insmod part_gpt
|
|
insmod ext2
|
|
|
|
search --no-floppy --fs-uuid --set 9bd58889-add7-410c-bdb7-1fbc2af9b0e1
|
|
echo 'loading ACRN...'
|
|
multiboot2 /boot/acrn/acrn.bin root=PARTUUID="e515916d-aac4-4439-aaa0-33231a9f4d83"
|
|
module2 /boot/bzImage Linux_bzImage
|
|
}
|
|
|
|
.. note::
|
|
Update this to use the UUID (``--set``) and PARTUUID (``root=`` parameter)
|
|
(or use the device node directly) of the root partition (e.g.
|
|
``/dev/nvme0n1p2``). Hint: use ``sudo blkid <device node>``.
|
|
|
|
Update the kernel name if you used a different name as the source
|
|
for your Service VM kernel.
|
|
|
|
Add the ``menuentry`` at the bottom of :file:`40_custom`, keep the
|
|
``exec tail`` line at the top intact.
|
|
|
|
#. Modify the ``/etc/default/grub`` file to make the Grub menu visible when
|
|
booting and make it load the Service VM kernel by default. Modify the
|
|
lines shown below:
|
|
|
|
.. code-block:: none
|
|
|
|
GRUB_DEFAULT=ubuntu-service-vm
|
|
#GRUB_TIMEOUT_STYLE=hidden
|
|
GRUB_TIMEOUT=5
|
|
GRUB_CMDLINE_LINUX="text"
|
|
|
|
#. Update Grub on your system:
|
|
|
|
.. code-block:: none
|
|
|
|
$ sudo update-grub
|
|
|
|
Enable Network Sharing for the User VM
|
|
======================================
|
|
|
|
In the Ubuntu Service VM, enable network sharing for the User VM:
|
|
|
|
.. code-block:: none
|
|
|
|
$ sudo systemctl enable systemd-networkd
|
|
$ sudo systemctl start systemd-networkd
|
|
|
|
|
|
Reboot the System
|
|
=================
|
|
|
|
Reboot the system. You should see the Grub menu with the new **ACRN
|
|
ubuntu-service-vm** entry. Select it and proceed to booting the platform. The
|
|
system will start Ubuntu and you can now log in (as before).
|
|
|
|
To verify that the hypervisor is effectively running, check ``dmesg``. The
|
|
typical output of a successful installation resembles the following:
|
|
|
|
.. code-block:: none
|
|
|
|
$ dmesg | grep ACRN
|
|
[ 0.000000] Hypervisor detected: ACRN
|
|
[ 0.862942] ACRN HVLog: acrn_hvlog_init
|
|
|
|
|
|
Additional Settings in the Service VM
|
|
=====================================
|
|
|
|
BIOS Settings of GVT-d for WaaG
|
|
-------------------------------
|
|
|
|
.. note::
|
|
Skip this step if you are using a Kaby Lake (KBL) Intel NUC.
|
|
|
|
Go to **Chipset** -> **System Agent (SA) Configuration** -> **Graphics
|
|
Configuration** and make the following settings:
|
|
|
|
Set **DVMT Pre-Allocated** to **64MB**:
|
|
|
|
.. figure:: images/DVMT-reallocated-64mb.png
|
|
|
|
Set **PM Support** to **Enabled**:
|
|
|
|
.. figure:: images/PM-support-enabled.png
|
|
|
|
Use OVMF to Launch the User VM
|
|
------------------------------
|
|
|
|
The User VM will be launched by OVMF, so copy it to the specific folder:
|
|
|
|
.. code-block:: none
|
|
|
|
$ sudo mkdir -p /usr/share/acrn/bios
|
|
$ sudo cp /home/acrn/work/acrn-hypervisor/devicemodel/bios/OVMF.fd /usr/share/acrn/bios
|
|
|
|
Build and Install the RT Kernel for the Ubuntu User VM
|
|
------------------------------------------------------
|
|
|
|
Follow these instructions to build the RT kernel.
|
|
|
|
#. Clone the RT kernel source code:
|
|
|
|
.. note::
|
|
This guide assumes you are doing this within the Service VM. This
|
|
**acrn-kernel** repository was already cloned under ``/home/acrn/work``
|
|
earlier on so you can just ``cd`` into it and perform the ``git checkout``
|
|
directly.
|
|
|
|
.. code-block:: none
|
|
|
|
$ git clone https://github.com/projectacrn/acrn-kernel
|
|
$ cd acrn-kernel
|
|
$ git checkout 4.19/preempt-rt
|
|
$ make mrproper
|
|
|
|
.. note::
|
|
The ``make mrproper`` is to make sure there is no ``.config`` file
|
|
left from any previous build (e.g. the one for the Service VM kernel).
|
|
|
|
#. Build the kernel:
|
|
|
|
.. code-block:: none
|
|
|
|
$ cp x86-64_defconfig .config
|
|
$ make olddefconfig
|
|
$ make targz-pkg
|
|
|
|
#. Copy the kernel and modules:
|
|
|
|
.. code-block:: none
|
|
|
|
$ sudo mount /dev/sda2 /mnt
|
|
$ sudo cp arch/x86/boot/bzImage /mnt/boot/
|
|
$ sudo tar -zxvf linux-4.19.72-rt25-x86.tar.gz -C /mnt/lib/modules/
|
|
$ sudo cp -r /mnt/lib/modules/lib/modules/4.19.72-rt25 /mnt/lib/modules/
|
|
$ sudo cd ~ && sudo umount /mnt && sync
|
|
|
|
.. rst-class:: numbered-step
|
|
|
|
Launch the RTVM
|
|
***************
|
|
|
|
Grub in the Ubuntu User VM (RTVM) needs to be configured to use the new RT
|
|
kernel that was just built and installed on the rootfs. Follow these steps to
|
|
perform this operation.
|
|
|
|
Update the Grub File
|
|
====================
|
|
|
|
#. Reboot into the Ubuntu User VM located on the SATA drive and log on.
|
|
|
|
#. Update the ``/etc/grub.d/40_custom`` file as shown below.
|
|
|
|
.. note::
|
|
Enter the command line for the kernel in ``/etc/grub.d/40_custom`` as
|
|
a single line and not as multiple lines. Otherwise, the kernel will
|
|
fail to boot.
|
|

|
|
}
|
|
|
|
.. note::
|
|
Update this to use the UUID (``--set``) and PARTUUID (``root=`` parameter)
|
|
(or use the device node directly) of the root partition (e.g. ``/dev/sda2).
|
|
Hint: use ``sudo blkid /dev/sda*``.
|
|
|
|
Update the kernel name if you used a different name as the source
|
|
for your Service VM kernel.
|
|
|
|
Add the ``menuentry`` at the bottom of :file:`40_custom`, keep the
|
|
``exec tail`` line at the top intact.
|
|
|
|
#. Modify the ``/etc/default/grub`` file to make the grub menu visible when
|
|
booting and make it load the RT kernel by default. Modify the
|
|
lines shown below:

|
|
GRUB_DEFAULT=ubuntu-user-vm
|
|

Configure RDT
|
|
-------------
|
|
|
|
In addition to setting the CAT configuration via HV commands, we allow
|
|
developers to add CAT configurations to the VM config and configure
|
|
automatically at the time of RTVM creation. Refer to :ref:`rdt_configuration`
|
|
for details on RDT configuration and :ref:`hv_rdt` for details on RDT
|
|
high-level design.
|
|
|
|
Set Up the Core Allocation for the RTVM
|
|
---------------------------------------
|
|
|
|
In our recommended configuration, two cores are allocated to the RTVM:
|
|
core 0 for housekeeping and core 1 for RT tasks. In order to achieve
|
|
this, follow the below steps to allocate all housekeeping tasks to core 0:
|
|
|
|
#. Prepare the RTVM launch script
|
|
|
|
Follow the `Passthrough a hard disk to RTVM`_ section to make adjustments to
|
|
the ``/usr/share/acrn/launch_hard_rt_vm.sh`` launch script.
|
|
|
|
#. Launch the RTVM:
|
|
|
|
.. code-block:: none
|
|
|
|
$ sudo /usr/share/acrn/launch_hard_rt_vm.sh
|
|
|
|
#. Log in to the RTVM as root and run the script as below:
|
|
|
|
.. code-block:: none
|
|
|
|
#!/bin/bash

|
# Copyright (C) 2019 Intel Corporation.
|

|
|
# Move all IRQs to core 0.
|
|
for i in `cat /proc/interrupts | grep '^ *[0-9]*[0-9]:' | awk {'print $1'} | sed 's/:$//' `;
|
|
do
|
|
echo setting $i to affine for core zero
|
|
echo 1 > /proc/irq/$i/smp_affinity
|
|
done
|
|
|
|
# Move all rcu tasks to core 0.
|
|
for i in `pgrep rcu`; do taskset -pc 0 $i; done
|
|
|
|
# Change real-time attribute of all rcu tasks to SCHED_OTHER and priority 0
|
|
for i in `pgrep rcu`; do chrt -v -o -p 0 $i; done
|
|
|
|
# Change real-time attribute of all tasks on core 1 to SCHED_OTHER and priority 0
|
|
for i in `pgrep /1`; do chrt -v -o -p 0 $i; done
|
|
|
|
# Change real-time attribute of all tasks to SCHED_OTHER and priority 0
|
|
for i in `ps -A -o pid`; do chrt -v -o -p 0 $i; done
|
|
|
|
echo disabling timer migration
|
|
echo 0 > /proc/sys/kernel/timer_migration
|
|
|
|
.. note:: Ignore the error messages that might appear while the script is
|
|
running.

Run Cyclictest
|
|
--------------
|
|
|
|
#. Refer to the :ref:`troubleshooting section <enabling the network on the RTVM>`
|
|
below that discusses how to enable the network connection for RTVM.
|
|
|
|
#. Launch the RTVM and log in as root.
|
|
|
|
#. Install the ``rt-tests`` tool:
|
|
|
|
.. code-block:: none
|
|
|
|
# apt install rt-tests
|
|
|
|
#. Use the following command to start cyclictest:
|
|
|
|
.. code-block:: none
|
|
|
|
# cyclictest -a 1 -p 80 -m -N -D 1h -q -H 30000 --histfile=test.log
|
|
|
|
|
|
Parameter descriptions:
|
|
|
|
:-a 1: to bind the RT task to core 1
|
|
:-p 80: to set the priority of the highest prio thread
|
|
:-m: lock current and future memory allocations
|
|
:-N: print results in ns instead of us (default us)
|
|
:-D 1h: to run for 1 hour, you can change it to other values
|
|
:-q: quiet mode; print a summary only on exit
|
|
:-H 30000 --histfile=test.log: dump the latency histogram to a local file
|
|
|
|
.. rst-class:: numbered-step
|
|
|
|
Launch the Windows VM
|
|
*********************
|
|
|
|
#. Follow this :ref:`guide <using_windows_as_uos>` to prepare the Windows
|
|
image file and then reboot with a new ``acrngt.conf``.
|
|
|
|
#. Modify the ``launch_uos_id1.sh`` script as follows and then launch
|
|
the Windows VM as one of the post-launched standard VMs:
