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: Add Capsule On Disk related definition.

2019-06-26T07:10:40+00:00

REF: https://github.com/tianocore/tianocore.github.io/wiki/ UEFI-Capsule-on-Disk-Introducation This patch will add Capsule On Disk related definition, including GUID, PPI and PCDs: The Capsule On Disk Name GUID indicates the capsule is to store Capsule On Disk file names. The Pei Capsule On Disk PPI provides service to retrieve capsules from Capsule On Disk temp relocation file on mass storage devices and create capsule hob for these capsules. Pei Boot In CapsuleOnDisk Mode Ppi indicates current boot mode is capsule on disk mode. PcdCapsuleOnDiskSupport is used to enable/disable Capsule On Disk. PcdCapsuleInRamSupport is used to enable/disable Capsule In Ram. PcdCoDRelocationFileName specifies the Capsule On Disk temp relocation file name. PcdCodRelocationDevPath specifies platform specific device to store Capsule On Disk temp relocation file.
