| <dd>We use <a class="reference external" href="http://buildroot.net/">http://buildroot.net/</a> as the build system for assembling a firmware |
| image. <cite>op-build</cite> is a “Buildroot overlay”. We build a kernel and initramfs |
| using buildroot to run the Petitboot boot loader in. We maintain a branch |
| with a minimum number of patches on top of upstream buildroot.</dd> |

| <dd>the Self Boot Engine is the first unit inside the POWER processor to start |

| <dd>The OpenPOWER Abstraction Layer, provided by skiboot</dd> |
| <dt><a class="reference external" href="https://open-power.github.io/skiboot/">skiboot</a></dt> |
| <dd>skiboot implements OPAL (the OpenPOWER Abstraction Layer). Skiboot is |
| boot and runtime firmware and is responsible for bringing up PCI and |
| providing runtime abstractions to the running OS.</dd> |
| <dt><a class="reference external" href="https://github.com/open-power/linux">Linux</a></dt> |
| <dd>Once skiboot has finished setting up the machine, it hands control over |
| to a Linux kernel. This kernel provides device drivers and userspace to |
| run the bootloader, Petitboot. We maintain our own branch with a minimal |
| number of patches on top of the latest upstream stable release.</dd> |
| <dt><a class="reference external" href="https://github.com/open-power/petitboot/">Petitboot</a></dt> |
| <dd>The bootloader. It is a normal user-space process running on Linux that |
| searches the system for disks and network devices that it can boot the |
| OS from.</dd> |

| <h2>Introductory Videos<a class="headerlink" href="#introductory-videos" title="Permalink to this headline">¶</a></h2> |
| <p>There are a number of good recorded presentations from various conferences |
| around the world that have overviews and deep dives into various parts of |
| the firmware stack.</p> |
| <p>Here, we present technical presentations that may be useful in learning |
| about topics relevant to OpenPOWER firmware development.</p> |
