LAVA is the job scheduler for building Linux kernel based on configured system (ex: ARM board).
This page describes how to setup tools and run in your local machine.
Currently, LAVA is supported only in Debian system. I'm using Docker to run it.
Kernel CI is the automated Linux kernel testing framework. It consists of several software components.
LAVA is the core part of Kernel CI. Kernel CI consists of LAVA and other software components.
Why do we need this tool?
Simply, it is developed for detecting regression problem efficiently
- Build Linux kernel automatically
- Kconfig -> build -> boot -> check the status of kernel image
For my private reason,
- Test Linux kernel on several ARM SBCs
To build Linux kernel fast, higher performance host system is required.
It seems Linaro uses Xeon servers. I use Zotac Intel Core i7-4770T barebone system.
OS - Debian
I prefer Docker because I don't want to install new system for this.
$ docker pull debian:jessie $ docker images REPOSITORY TAG IMAGE ID CREATED SIZE debian jessie-backports 8d3e0261e9ea 2 weeks ago 123 MB
The option, '-p 8000:80' enables accessing the LAVA web pages inside the container through web browser with the url, 'http://localhost:8000'.
$docker run -p 8000:80 -i -t 8d3e0261e9ea /bin/bash Run debian (8d3e0261e9ea) [email protected]:/#
Now, you are inside the Debian container.
Let's install the LAVA. Jessie backport supports it, so additional deb is required in /etc/apt/sources.list.
[email protected]:/# apt update [email protected]:/# apt-get install vim [email protected]:/# vim /etc/apt/sources.list # Add this line for LAVA setup deb http://deb.debian.org/debian/ jessie-backports main
Then, install the postgresql.
[email protected]:/# apt update [email protected]:/# apt-get install postgresql
Postgresql service should start prior to installing LAVA. If it doesn't starts, then port 5432 error will occur.
[email protected]:/# service postgresql start [email protected]:/# apt-get install -t jessie-backports lava
Let's create admin account for LAVA
[email protected]:/# lava-server manage createsuperuser
Start the LAVA service.
[email protected]:/# service lava-server start
After LAVA installation,
