ArmPkg: 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

ArmPkg: Remove ARM32 Comments and Supported Arch

ArmPkg: Remove UGA support

2025-07-08T15:42:03+00:00

The Universal Graphics Adapter (UGA) is a graphic abstraction. The UGA I/O and Draw protocols are deprecated since UEFI 2.0 was introduced. Cf. the UEFI spec v2.9: "Appendix L - EFI 1.10 Protocol Changes and Deprecation List" section L.2 "Deprecated Protocols" Remove the UGA support. Signed-off-by: GuoMinJ Signed-off-by: Pierre Gondois

ArmPkg: Configure PcdEmuVariableNvModeEnable as a dynamic PCD

2023-05-29T15:14:00+00:00

The PCD gEfiMdeModulePkgTokenSpaceGuid.PcdEmuVariableNvModeEnable indicates if a variable driver will emulate the variable NV mode. This PCD is defined as [PcdsFixedAtBuild, PcdsPatchableInModule, PcdsDynamic, PcdsDynamicEx]. Some firmware builds may define this PCD as a dynamic PCD and initialise the value at runtime. Therefore, move the PCD declaration from the [FixedPcd] section to the [Pcd] section in the platform boot manager library file PlatformBootManagerLib.inf. Without this change the build would not succeed. Signed-off-by: Sami Mujawar Reviewed-by: Ard Biesheuvel

ArmPkg/PlatformBootManagerLib: Add path to boot UEFI Shell over UiApp

2023-05-04T14:26:58+00:00

The UEFI Shell is a non-active boot option, at the opposite of UiApp. If no valid boot option is found, UiApp is selected. UiApp requires a human interaction. When installing a new EDKII image in CIs or when scripting is required, this is problematic. If no valid boot option is discovered, add a path to directly go to the UEFI Shell where the startup.nsh script is automatically executed. The UEFI Shell is launched after connecting possible devices, but before the reset that is meant to automatically make them visible. The new PcdUefiShellDefaultBootEnable must be set to TRUE to enable this behaviour. The Pcd is set to false by default. Signed-off-by: Pierre Gondois Tested-by: Patrik Berglund

ArmPkg: Update code to be more C11 compliant by using func

2023-04-10T14:19:57+00:00

__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among others support, while __func__ was standardized in C99. Since it's more standard, replace __FUNCTION__ with __func__ throughout ArmPkg. Signed-off-by: Rebecca Cran Reviewed-by: Michael D Kinney Reviewed-by: Ard Biesheuvel

This commit adds code which check BootDiscoveryPolicy variable and calls Boot Policy Manager Protocol to connect device specified by the variable. To enable that mechanism for platform EfiMdeModulePkgTokenSpaceGuid.PcdBootDiscoveryPolicy PCD must be added to DSC file and BootDiscoveryPolicyUiLib should be added to UiApp libraries.
