Software Setup
|
||
**************
|
||
|
||
Please follow the :ref:`getting-started-apl-nuc`, with the following changes:
|
||
|
||
1. Set up a Clear Linux Operating System
|
||
|
||
Clear Linux 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 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
|
||

|
||
|
||
#. 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
