Initial Machine Setup

This applies to the LAVA infrastructure i.e. Dispatcher and Scheduler

As for the KernelCI/PowerCI FrontEnd, a different virtual machine could be considered.

We herein assume the host machine (virtual or not) is Ubuntu 14+, with a sudoer user powerci, and a configured static IP address.

The machine name shall be lab-baylibre

preliminary packages and services installation

sudo apt-get install openssh-server vim gitk git-gui pandoc lynx terminator conmux minicom repo qemu gcc-arm-linux-gnueabi tree meld

some required packages like ser2net and tftp-hpa are part of the lava macro package.

Re-instate vim as the standard editor with:

sudo update-alternatives --config editor

Repo init

Make sure to create an ssh id_rsa.pub key for the powerci user, and add it to the various git repos used (baylibre and github)

mkdir -p /home/powerci/POWERCI && cd POWERCI

repo init -u [email protected]:mtitinger/powerci-manifests.git

repo sync

Lava installation

Adding the repository

According to the documentation, do the following:

sudo apt-get upgrade

wget http://images.validation.linaro.org/trusty-repo/trusty-repo.key.asc

sudo apt-key add trusty-repo.key.asc

sudo apt-get update

Installing the LAVA "full set"

sudo apt-get install lava

NFS is installed by the lava pkg, with exports defaulting to /var/lib/lava/dispatcher/tmp
TFTP-HPA is installed by the lava pkg, with exports defaulting to /var/lib/lava/dispatcher/tmp (see /etc/default/tftpd-hpa)

Interactive installation option

standalone server
Name "lab-baylibre"
Postgres port 5432
internet site config for email
fully qualified domain name: baylibre.com

LAVA fs-overlays

Some standard LAVA-debian files needs being simlinked to this repo, like for instance:

sudo ln -s ~/POWERCI/fs-overlay/etc/lava-dispatcher/device-types /etc/lava-dispatcher/device-types

check in fs-overlay to not miss anything, for instance:

General server branding

/etc/lava-server/settings.conf
/etc/apache2/sites-available/powerci.conf

Dispatcher Population

/etc/ser2net.conf
/etc/lava-dispatcher/device-types
/etc/lava-dispatcher/devices

Initial LAVA Server Administration

Apache site enabling

Query the active site with:


powerci@lab-baylibre:~$ sudo a2query -s
000-default (enabled by site administrator)

You may now disable the default site, and enable the lava instance:

sudo a2dissite 000-default

sudo a2ensite lava-server.conf

sudo service apache2 restart

Create the LAVA superuser account

sudo lava-server manage createsuperuser --username lab-admin --email=[email protected]

password: powerci

for debug only, it is recommended to settings the log level for the server to 'debug', in file /etc/init.d/lava-server

LAB Setup

This section is aimed on the dispatcher and Lab configuration.

This dispatcher may be on a different machine, physically connected to the boards.

See setup-lab.md

Posting Jobs, using LAVA

This section is about using scripts and lava-tools to posting jobs.

This requires the dispatcher to be setup, and will describe what to do as a user.

See user-jobs.md
