UefiPayloadPkg: 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

UefiPayloadPkg: Enable processing of capsules

2025-08-25T11:54:17+00:00

Make UefiPayloadPkg.dsc add required libraries/DXEs/PCDs when CAPSULE_SUPPORT define is set to TRUE. UefiPayloadEntry now parses firmware information from a bootloader and switches boot mode to BOOT_ON_FLASH_UPDATE if there are any capsules. It's not guarded by any PCD under the assumption that bootloader won't pass capsules if EDK shouldn't be handling them. EsrtDxe is enabled to manage ESRT entries and it consumes the firmware information HOB created by UefiPayloadEntry. ProcessCapsules() internally looks up EsrtManagementProtocol and calls SyncEsrtFmp() to import data from available FMP instances. PlatformBootManagerLib was made to call ProcessCapsules() twice: before and after end-of-DXE. Signed-off-by: Sergii Dmytruk

UefiPayloadPkg: 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

UefiPayloadPkg: Fix boot shell issue for universal UEFI payload

2023-05-15T21:26:04+00:00

After moving BDS driver to a new FV for universal UEFI payload, the shell boot option path is not correct since it used the BDS FV instead of DXE FV in its device path. This patch would find the correct FV by reading shell file. It also removed PcdShellFile by using gUefiShellFileGuid.
