Software Setup
|
|
**************
|
|
|
|
Please follow the :ref:`getting-started-apl-nuc`, with the following changes:
|
|
|
|
1. Set up a Clear Linux Operating System
|
|
|
|
Clear Linux OS will update to the latest version during installation.
|
|
Run this command (as root) to roll back to version 25130, using the
|
|
``-x`` switch to ignore version mismatch::
|
|
|
|
# swupd verify -x --fix --picky -m 25130
|
|
# swupd autoupdate --disable
|
|
# reboot
|
|
|
|
#. Add the ACRN hypervisor to the EFI Partition
|
|
|
|
Refer to :ref:`getting-started-building`
|
|
to build the hypervisor, device model, and tools.
|
|
|
|
Download and untar this `skl-patches-for-acrn.tar file
|
|
<../_static/downloads/skl-patches-for-acrn.tar>`_, apply these patches to the
|
|
acrn-hypervisor, and build it::
|
|
|
|
$ git clone https://github.com/projectacrn/acrn-hypervisor
|
|
$ cd acrn-hypervisor
|
|
$ git checkout acrn-2018w39.6-140000p
|
|
$ curl https://projectacrn.github.io/latest/_static/downloads/skl-patches-for-acrn.tar | tar x
|
|
$ git am *.patch
|
|
$ make
|
|
|
|
This build process creates new ``acrn-dm``, ``acrn.efi`` and
|
|
``launch_uos.sh`` files.
|
|
|
|
#. Replace ``acrn-dm`` with this new version (as root)::
|
|
|
|
# cp build/devicemodel/acrn-dm /usr/bin/acrn-dm
|
|
|
|
#. Put the new ``acrn.efi`` hypervisor application (included in the
|
|
Clear Linux OS release) on the EFI partition (as root)::
|
|
|
|
# mount /dev/nvme0n1p1 /mnt
|
|
# mkdir /mnt/EFI/acrn
|
|
# cp build/hypervisor/acrn.efi /mnt/EFI/acrn/
|
|
|
|
#. Configure the EFI firmware to boot the ACRN hypervisor by default.
|
|
This assumes you are on an NVMe SSD as in the Skull Canyon::
|
|
|
|
# efibootmgr -c -l "\EFI\acrn\acrn.efi" -d /dev/nvme0n1 -p 1 -L "ACRN"
|
|
|
|
#. Create a boot entry for ACRN Service OS by making a few edits to the
|
|
``acrn.conf`` file (note the options line must be one long line, without
|
|
any line breaks)::
|
|
|
|
# vim /mnt/loader/entries/acrn.conf
|
|
title The ACRN Service OS
|
|
linux /EFI/org.clearlinux/kernel-org.clearlinux.pk414-sos.4.14.68-99
|
|

|
|
|
|
#. Don't Enable weston service (skip this step found in the NUC's getting
|
|
started guide).
|
|
|
|
#. Set up Reference UOS by running the modified ``launch_uos.sh`` in
|
|
``acrn-hypervisor/devicemodel/samples/nuc/launch_uos.sh``
|
|
|
|
#. After UOS is launched, do these steps to run GFX workloads:
|
|
|
|
a) install weston and glmark2::
|
|
|
|
#swupd bundle-add desktop glmark2
|
|
#) Add new user cl_uos::
|
|
|
|
# useradd cl_uos
|
|
# passwd cl_uos
|
|
# usermod -G wheel -a cl_uos
|
|
#) Enable weston service::
|
|
|
|
# systemctl enable weston@cl_uos
|
|
# systemctl start weston@cl_uos
|
|
#) Disable weston screen saver::
|
|
|
|
# vim .config/weston.ini
|
|
[core]
|
|
idle-time=0
|
|
#) run glmark2::
|
|
|
|
# glmark2-es2-wayland
|
