This repository is part of Project Mu. Please see Project Mu for details https://microsoft.github.io/mu

This MM Supervisor feature repo contains the supervisor module under Standalone MM environment for X64 architecture, refactored from TianoCore common modules and public portion of AMD SMM supervisor module. The repo intends to support operating Standalone MM modules in a secure manner. Other peripheral libraries are also included to accomodate user module operations.

Detailed Feature Information

Repository Philosophy

Like other Project MU feature repositories, the Project MU MM Supervisor feature repo does not strictly follow the EDKII releases, but instead has a continuous main branch which will periodically receive cherry-picks of needed changes from EDKII. For stable builds, release tags will be used instead to determine commit hashes at stable points in development. Release branches may be created as needed to facilitate a specific release with needed features, but this should be avoided.

Consuming the MM Supervisor Feature Package

Since this project does not follow the release fork model, the code should be consumed from a release hash and should be consumed as a extdep in the platform repo. To include, create a file named feature_mm_supv_ext_dep.yaml desired release tag hash. This could be in the root of the project or in a subdirectory as desired.

{

"scope": "global",

"type": "git",

"name": "FEATURE_MM_SUPV",

"var_name": "FEATURE_MM_SUPV_PATH",

"source": "https://github.com/microsoft/mu_feature_mm_supv.git",

"version": "<RELEASE HASH>",

"flags": ["set_build_var"]

}

Setting the the var_name and the set_build_var flags will allow the build scripts to reference the extdep location. To make sure that the package is discoverable for the build, the following line should also be added to the build MM supervisor GetPackagesPath list.

shell_environment.GetBuildVars().GetValue("FEATURE_MM_SUPV_PATH", "")

Note: If using pytool extensions older then version 0.17.0 you will need to append the root path to the build variable string.

After this the package should be discoverable to can be used in the build like any other dependency.
