OvmfPkg: 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. Note: Headers taken directly from external projects, such as those in OvmfPkg/Include/IndustryStandard/Xen/ were not modified since they may be periodically re-synced and do not follow other edk2 coding stadards. 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

OvmfPkg: Remove OVMF IA32

2025-09-09T18:49:32+00:00

This commit removes OVMF IA32 from edk2 per RFC https://edk2.groups.io/g/devel/topic/rfc_remove_ovmf_ia32_and/114152215. OVMF IA32 is a 32 bit only platform that no longer represents the vast majority of physical platforms. The RFC details more reasoning in much more depth. OVMF IA32 will be kept in a branch off the edk2-stable202508 tag for any long term consumers; it will receive build break updates only (e.g. if an upstream submodule changes location).

OvmfPkg/LoadLinuxLib: list "LoadLinuxLib.h" in the INF file

2018-03-13T13:30:41+00:00

The header file declares the InitLinuxDescriptorTables() and SetLinuxDescriptorTables() functions, which are called from "Linux.c" and implemented in "LinuxGdt.c". The header file also declares the JumpToKernel() and JumpToUefiKernel() functions, which are similarly called from "Linux.c". They are implemented (dependent on architecture) in "Ia32/JumpToKernel.nasm" and "X64/JumpToKernel.nasm".
