# OpenBMC

[![Build Status](https://jenkins.openbmc.org/buildStatus/icon?job=latest-master)](https://jenkins.openbmc.org/job/latest-master/)

OpenBMC is a Linux distribution for management controllers used in devices such
as servers, top of rack switches or RAID appliances. It uses
[Yocto](https://www.yoctoproject.org/),
[OpenEmbedded](https://www.openembedded.org/wiki/Main_Page),
[systemd](https://www.freedesktop.org/wiki/Software/systemd/), and
[D-Bus](https://www.freedesktop.org/wiki/Software/dbus/) to allow easy
customization for your platform.

## Setting up your OpenBMC project

### 1) Prerequisite

See the
[Yocto documentation](https://docs.yoctoproject.org/ref-manual/system-requirements.html#required-packages-for-the-build-host)
for the latest requirements

#### Ubuntu

```sh
sudo apt install git python3-distutils gcc g++ make file wget \
    gawk diffstat bzip2 cpio chrpath zstd lz4 bzip2
```

#### Fedora

```sh
sudo dnf install git python3 gcc g++ gawk which bzip2 chrpath cpio \
    hostname file diffutils diffstat lz4 wget zstd rpcgen patch
```

### 2) Download the source

```sh
git clone https://github.com/openbmc/openbmc
cd openbmc
```

### 3) Target your hardware

Any build requires an environment set up according to your hardware target.
There is a special script in the root of this repository that can be used to
configure the environment as needed. The script is called `setup` and takes the
name of your hardware target as an argument.

The script needs to be sourced while in the top directory of the OpenBMC
repository clone, and, if run without arguments, will display the list of
supported hardware targets, see the following example:

```text
$ . setup <machine> [build_dir]
Target machine must be specified. Use one of:

bletchley               mori                    s8036
dl360poc                mtjade                  swift

gsj                     s2600wf                 zaius
kudo                    s6q
lannister               s7106
```

Once you know the target (e.g. romulus), source the `setup` script as follows:

```sh
. setup romulus
```

### 4) Build

```sh
bitbake obmc-phosphor-image
```

repository.

## OpenBMC Development

The OpenBMC community maintains a set of tutorials new users can go through to
get up to speed on OpenBMC development out
[here](https://github.com/openbmc/docs/blob/master/development/README.md)

## Build Validation and Testing

Commits submitted by members of the OpenBMC GitHub community are compiled and
tested via our [Jenkins](https://jenkins.openbmc.org/) server. Commits are run
through two levels of testing. At the repository level the makefile `make check`
directive is run. At the system level, the commit is built into a firmware image
and run with an arm-softmmu QEMU model against a barrage of
[CI tests](https://jenkins.openbmc.org/job/CI-MISC/job/run-ci-in-qemu/).

Commits submitted by non-members do not automatically proceed through CI
testing. After visual inspection of the commit, a CI run can be manually
performed by the reviewer.

Automated testing against the QEMU model along with supported systems are
performed. The OpenBMC project uses the
[Robot Framework](http://robotframework.org/) for all automation. Our complete
test repository can be found
[here](https://github.com/openbmc/openbmc-test-automation).

## Submitting Patches

Support of additional hardware and software packages is always welcome. Please
follow the
[contributing guidelines](https://github.com/openbmc/docs/blob/master/CONTRIBUTING.md)
when making a submission. It is expected that contributions contain test cases.

## Bug Reporting

[Issues](https://github.com/openbmc/openbmc/issues) are managed on GitHub. It is
