MdeModulePkg: Replace include guards with #pragma once

2026-02-23T21:01:28+00:00

Replace traditional `#ifndef`/`#define`/`#endif` include guards with `#pragma` once. `#pragma once` is a widely supported preprocessor directive that prevents header files from being included multiple times. It is supported by all toolchains used to build edk2: GCC, Clang/LLVM, and MSVC. Compared to macro-based include guards, `#pragma once`: - Eliminates the risk of macro name collisions or copy/paste errors where two headers inadvertently use the same guard macro. - Eliminate inconsistency in the way include guard macros are named (e.g., some files use `__FILE_H__`, others use `FILE_H_`, etc.). - Reduces boilerplate (three lines replaced by one). - Avoids polluting the macro namespace with guard symbols. - Can improve build times as the preprocessor can skip re-opening the file entirely, rather than re-reading it to find the matching `#endif` ("multiple-include optimization"). - Note that some compilers may already optimize traditional include guards, by recognzining the idiomatic pattern. This change is made acknowledging that overall portability of the code will technically be reduced, as `#pragma once` is not part of the C/C++ standards. However, this is considered acceptable given: 1. edk2 already defines a subset of supported compilers in BaseTools/Conf/tools_def.template, all of which have supported `#pragma once` for over two decades. 2. There have been concerns raised to the project about inconsistent include guard naming and potential macro collisions. Approximate compiler support dates: - MSVC: Supported since Visual C++ 4.2 (1996) - GCC: Supported since 3.4 (2004) (http://gnu.ist.utl.pt/software/gcc/gcc-3.4/changes.html) - Clang (LLVM based): Since initial release in 2007 Signed-off-by: Michael Kubacki

MdeModulePkg/Capsule: Replace VariableLock with VariablePolicy

2025-11-24T06:23:55+00:00

Since VariableLock compromises security in the SMM environment, it is deprecated. Used VariablePolicy instead for stronger and more flexible UEFI variable protection. Ref: [acd66e4] Cc: Sachin Ganesh Signed-off-by: Sathya Ravichandran

MdeModulePkg: Remove ARM32 Support

MdeModulePkg/Capsule: Remove RT restriction in UpdateCapsule service.

2020-02-07T07:43:00+00:00

Current UpdateCapsule service will reject all non-reset capsule images and return EFI_OUT_OF_RESOURCE if the system is at runtime. This will block a platform CapsuleLib from implementing ProcessCapsuleImage() with runtime capsule processing capability. This patch removes this restriction. The change is controled by a feature PCD PcdSupportProcessCapsuleAtRuntime, and the default value is FALSE which means not enable this feature.
