2026-02-24	DynamicTablesPkg: Replace include guards with #pragma once	Michael Kubacki	1	-4/+1
	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 <michael.kubacki@microsoft.com>
2025-09-30	DynamicTablesPkg: Add SMBIOS table generation	Girish Mahadevan	1	-0/+17
	Add the SMBIOS Table generator code to the DynamicTablesPkg. This change includes adding new logic to the DynamicTableManager to process and add SMBIOS tables and augmenting the existing SMBIOS Factory generator to include installing multiple SMBIOS tables.

2025-09-30	DynamicTablesPkg: Move ACPI building & change DEPEX on protocol	Girish Mahadevan	1	-0/+17
	In preparation to introduce Dynamic SMBIOS support the following 2 changes are required: 1. Use ProtocolNotify Event for generating the ACPI tables and don't include the ACPI protocol in the Depex section for DynamicTableManagerDxe Driver. This is because if a platforms doesn't do ACPI based boot or if doesn't want to install SMBIOS tables we still want the DynamicTableManager to be dispatched to install the SMBIOS or ACPI tables respectively. 2. Split the logic for building the ACPI tables to a separate file. Signed-off-by: Girish Mahadevan <gmahadevan@nvidia.com>
2024-07-29	DynamicTablesPkg: DynamicTableManagerDxe: Refactor PresenceArray	Pierre Gondois	1	-0/+63
	Mandatory ACPI tables depend on the architectures. Different architectures might also want to check other tables. Move mAcpiVerifyTables containing the list of ACPI tables to check to an arch specific file and introduce GetAcpiTablePresenceInfo() to get get the relevant information from the array.
