Project Mu


Project Mu is an open source release of the UEFI core used in Microsoft Surface and Hyper-V products initiated by Microsoft in December 2018. The project promotes the idea of Firmware as a Service. The project's GitHub page describes the project as follows
Project Mu is a modular adaptation of TianoCore's edk2 tuned for building modern devices using a scalable, maintainable, and reusable pattern. Mu is built around the idea that shipping and maintaining a UEFI product is an ongoing collaboration between numerous partners. For too long the industry has built products using a "forking" model combined with copy/paste/rename and with each new product the maintenance burden grows to such a level that updates are near impossible due to cost and risk.

The project was started to replace TianoCore's edk2 implementation to improve quality tests of the competing open source UEFI core.
