Tianocore EDK II is the UEFI reference implementation by Intel. EDK is the abbreviation for EFI Development Kit and is developed by the TianoCore community.[1] TianoCore EDK II is the defacto standard generic UEFI services implementation.[2]

History[edit]

In 2004, Intel released their "Foundation Code" of their EFI implementation using a free license. This later evolved into EDK and EDK II, within the TianoCore community.[1] EDK II was released in 2010 under the package known as "UEFI Development Kit" (UDK2010).[3]

Although EDK II implements the UEFI specification, it is not endorsed by the UEFI forum.[1]

Projects[edit]

EDK II code has been integrated into other projects.

Coreboot[edit]

In 2013, project PIANO was merged into Coreboot.[4] It gained EDK II support in 2017.[5]

Project Mu[edit]

Microsoft has developed their own EDK-II build named Project Mu.[6] It is a fork of EDK II.[7]

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.[8] The project promotes the idea of Firmware as a Service.[9] 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.[10]

The project was started to replace TianoCore's edk2 implementation to improve quality tests of the competing open source UEFI core.[11]

EFIDroid[edit]

EFIDroid is a bootloader for Android devices based on Snapdragon processors that is based on EDK-II.[12]
