OpenBMC

The OpenBMC project is a Linux Foundation collaborative open-source project that produces an open source implementation of the baseboard management controllers (BMC) firmware stack. OpenBMC is a Linux distribution for BMCs meant to work across heterogeneous systems that include enterprise, high-performance computing (HPC), telecommunications, and cloud-scale data centers.

History
In 2014, four Facebook programmers at a Facebook hackathon event created a prototype open-source BMC firmware stack named OpenBMC. In 2015, IBM collaborated with Rackspace on an open-source BMC firmware stack also named OpenBMC. These projects were similar in name and concept only. In March 2018, OpenBMC became a Linux Foundation project and converged on the IBM stack. Founding organizations of the OpenBMC project are Microsoft, Intel, IBM, Google, and Facebook. A technical steering committee was formed to guide the project with representation from the five founding companies. Brad Bishop from IBM was elected chair of the technical steering committee. In April 2019, Arm Holdings joined as the 6th member of the OpenBMC technical steering committee.

Features
OpenBMC uses the Yocto Project as the underlying building and distribution generation framework. The firmware itself is based on U-Boot. OpenBMC uses D-Bus as an inter-process communication (IPC). OpenBMC includes a web application for interacting with the firmware stack. OpenBMC added Redfish support for hardware management.
