DynamicTablesPkg/AcpiFadtLib: Preserve platform flags on Arm and RISC-V

2026-09-25T15:32:56+00:00

BuildFadtTable() adds platform-provided fixed-feature flags before calling FadtArchUpdate(). The Arm and RISC-V implementations assign Fadt->Flags, discarding the flags already added by the platform. Use bitwise OR assignment to add architecture defaults without overwriting the existing flags. Leave the generation order, validation masks, ACPI revision handling, and architecture defaults unchanged. Signed-off-by: Djordje Nedic

EmbeddedPkg,MdeModulePkg,DynamicTablesPkg: Move ACPI helper macros

2026-06-18T13:03:24+00:00

Move the ACPI table helper macros from EmbeddedPkg's AcpiLib.h to MdeModulePkg's AcpiHelperMacros.h. These macros describe ACPI data initializers and do not depend on the AcpiLib library interface. Keeping them in AcpiLib.h forces users that only need the macros to include the AcpiLib library header unnecessarily. Place the macros in a common MdeModulePkg public header so ACPI table producers can include the macro definitions directly without implying use of AcpiLib. The companion edk2-platforms change is: "Global: Include AcpiHelperMacros.h for ACPI helper macros" Tested: DynamicTablesPkg: X64/AARCH64 DEBUG/RELEASE/NOOPT MdeModulePkg: X64/AARCH64 DEBUG/RELEASE/NOOPT EmbeddedPkg: X64/AARCH64 DEBUG/RELEASE/NOOPT Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Varshit Pandya

DynamicTablesPkg: 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

DynamicTablesPkg: Drop ARM32 Support

2025-09-25T22:04:10+00:00

edk2 is dropping support for the ARM32 architecture. This commit removes ARM32 code from DynamicTablesPkg. This also drops irrelevant VALID_ARCHITECTURES comments from infs that are not arch specific. Signed-off-by: Oliver Smith-Denny

DynamicTablesPkg: Drop IA32 support

2025-09-22T18:24:48+00:00

All DynamicTablesPkg libraries and drivers execute in the DXE phase, where both AMD and Intel platforms operate in X64 (64-bit) mode. Therefore, IA32 (32-bit) support is no longer required for DynamicTablesPkg. Signed-off-by: Abdul Lateef Attar
