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: Implement abstract CM_OBJECT_TOKENs

2025-09-30T08:27:48+00:00

Abstract tokens simplify linking of generated tables. They allow for tables to be search for not just by existing ConfigurationManager object references, but also by arbitrary tokens generated by the table generators themselves. Signed-off-by: Sarah Walker

DynamicTablesPkg: Define a SMBIOS Structure/Table type

2025-09-30T08:27:48+00:00

SMBIOS Structure Types 0 through 127 (7Fh) are reserved for and defined by the SMBIOS specification. Types 128 through 256 (80h to FFh) are available for system and OEM-specific information. Therefore, define a new type 'SMBIOS_TABLE_TYPE' that represents a SMBIOS structure type and include it in the definition of CM_STD_OBJ_SMBIOS_TABLE_INFO.

DynamicTablesPkg: Add support to specify FADT minor revision

2022-07-15T18:07:49+00:00

The CM_STD_OBJ_ACPI_TABLE_INFO.AcpiTableRevision can be used to specify the major revision number of the ACPI table that the generator must use. Although most ACPI tables only have a major revision number, the FADT table additionally has a minor revision number. The FADT generator currently defaults to setting the latest supported ACPI revision for the FADT table i.e. ACPI 6.4. This means that the minor revision for the FADT table is always set to 4 and there is no provision for a user to specify the minor revision to be selected. Therefore, update CM_STD_OBJ_ACPI_TABLE_INFO to introduce a new field MinorRevision which can be used to specify the minor revision for an ACPI table. Also update the FADT generator to validate the supported FADT revisions ans use the specified minor revision for the FADT table if supported. If an unsupported minor revision is specified the FADT generator defaults to the latest supported minor revision. Since the CM_STD_OBJ_ACPI_TABLE_INFO.MinorRevision field is added to the end of the structure, it should not break existing platform code.

DynamicTablesPkg: Fix ACPI table rev field width

2020-03-29T16:53:35+00:00

The VS2017 compiler reports 'warning C4244: '=': conversion from 'const UINT32' to 'UINT8', possible loss of data' when the ACPI table revision field is being updated. The width of the revision field in the EFI_ACPI_DESCRIPTION_HEADER struct is 8-bit wide. Therefore, to fix the above warning make the ACPI Table revision field usage 8-bit wide across Dynamic Tables Framework. Signed-off-by: Sami Mujawar Reviewed-by: Alexei Fedorov
