Tianocore releases UDK2018

Tianocore, not the UEFI Forum, has released UDK2018, the latest UEFI Dev Kit, a snapshot of the EDK-II, tied to particular revision of the specs.








Windows UEFI development course

WinInsider — probably via Alex Ionescu — has a UEFI development course available.  Alex is the author of VisualUEFI, which hides the non-Visual Studio’isms of EDK-II development. Alex, along with others at Wininternals, is also one of the current authors of the “Windows Internals”  book from Microsoft Press, now a 2-volume 6th edition set, originally called “Inside Windows NT”, written by Helen Custer.

Windows UEFI Development (3 Days or 5 Days)

In this course, one can expect to learn the internals of the Unified Extensible Firmware Interface inside and out, from the high-level concepts and overview of its functionality, down to the low-level development of actual UEFI applications, drivers, and services. The seminar will go over the history of UEFI’s development, from its original “Intel Boot Initiative” days to today’s SecureBoot facilities (and controversies), discuss the core UEFI data structures that form the basis of the environment, describe the different internal boot phases of the UEFI Runtime, and go in detail over the main UEFI protocols and their semantics. The course will also cover how UEFI leverages several Microsoft technologies, such as Authenticode and the Portable Executable (PE) format. Finishing off the lecture section will be a deep dive on how Windows 8 and later take advantage of UEFI to support booting off GPT disks, implementing SecureBoot, and speeding up the boot experience. Windows user-mode and kernel-mode APIs that interact with UEFI, as well as internal kernel data structures and capabilities in the UEFI HAL will also be shown off. Alongside the lecture period, attendees will get their hands dirty with bare-to-the-metal UEFI development using Visual Studio, as well as learning how to setup the UEFI SDK (EDK) to work alongside Microsoft’s development tools. Participants will get the chance to build their own UEFI applications, drivers, and runtime services, as well as learn how to debug and test their work in the OVMF environment alongside QEMU, without requiring actual UEFI hardware. The course will also show how to develop and build SecureBoot-compatible binaries. Finally, attendees will discover the Windows-specific Boot Application Runtime Environment, how to build compatible applications, and how to leverage the environment from both a UEFI and PCAT perspective. Attendees will then write both offensive and defensive UEFI code that hooks and/or protects the Windows Boot Loader.

EDK-II upcoming Github changes

Laurie Jarlstrom of Intel announced on the EDK-II list about upcoming Sourceforge to Github hosting changes:

This message is an update on the transition from SourceForge to GitHub for EDK II development.  The schedule is currently targeting the last week of January or the first week of February to perform the transition.  The transition process should only take one to two days to complete.  A notification message will be sent the week prior to the actual dates that the repositories will be impacted.  This should provide adequate notification for the scheduled down time. As part of this transition some documentation and process changes have been required.  The updated process as well as other GitHub specific information can be found on the tianocore Wiki at the link provided below.  Feedback on this documentation is welcome and needed to make sure the transition is as smooth as possible.

EDK II specifications updated

Laurie Jarlstrom of Intel has announced a documentation update to the UEFI Forum’s EDK II Specifications:

“Announcing the V1.25 and V1.26 updates to the EDK II Specifications. Go to the EDK II Specifications page to download the latest documentation.”

These are the specs beyond the UEFI Forum’s PI and UEFI specs, focused on development implementation details of Tianocore’s EDK-II.



UEFI gets more IPMI 2.0 features

Daocheng Bu of Intel added new IPMI libraries to UEFI’s public EDK-I dev kit. Earlier, IPMI 2.0 definitions were added, now a library to support a generic PIMI submitt command has been added:

Update Ipmi2.0 definitions header file and MdeModulePkg.dsc
file for Ipmi libraries. Add Ipmi realted libraries to support
generic Ipmi submit command. Also add Ppi/Protocol definitions
that will be produced by Ipmi Peim and drivers.

  MdePkg: Update Ipmi2.0 definitions header file.
  MdeModulePkg: Add IpmiLib and Ppi/Protocol header file.
  MdeModulePkg: Add BaseIpmiLib Null Library Instance.
  MdeModulePkg: Add PeiIpmiLibIpmiPpi Library Instance.
  MdeModulePkg: Add DxeIpmiLibIpmiProtocol Library Instance.
  MdeModulePkg: Add SmmIpmiLibSmmIpmiProtocol Library Instance.
  MdeModulePkg: Update MdeModulePkg.dsc file for IpmiLib.

Tianocore web site updated

As reported by the Intel UEFI Twitter feed, the UEFI Forum’s web team have done a complete overhaul to the TianoCore.org web site:


There are a few other web pages, not many more; most others are github-hosted web pages now.

This news was found on the Twitter feed of Brian Richardson of Intel, which was not on my previous 0.3 release of Twitter feeds, but will be in next 0.4 release:

On a related note, the edk2-devel mailing list finally moved from SourceForge to 01.org:


Tutorial on using EDK-II’s Linux emulator

Today Jey Jay (LinuxKernelSeeker) has a blog post on how to use TianoCore with Linux, using the EDK2 emulator.

“This post will explains the steps involved in compiling EmulatorPkg of Tianocore EDK2. Who wish to learn UEFI can use this emulator for writing UEFI samples.” …

It is a good article, some of the Tianocore readmes for Linux are fairly vague (and/or referencing outdated distro releases that’re no longer available), so it is nice to have a tutorial talking about a fresh release, including some screenshots to be even more user-friendly.
