Global: Set MarkdownLintCheck plugin to AuditOnly

2026-07-29T12:32:09+00:00

In preparation for the MarkdownLintCheck plugin being added to the repo, this change defaults the plugin to `AuditOnly` mode in each package. This allows package maintainers to enable the plugin as they see fit. Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Michael Kubacki

FmpDevicePkg/FmpDxe: Reduce NV variable reads for FMP state

2026-07-20T05:44:52+00:00

In PopulateDescriptor(), each FMP device previously called GetFmpControllerState() multiple times through individual getter functions (GetVersionFromVariable, GetLowestSupportedVersionFromVariable, etc.), each performing a separate GetVariable() call to read the same FmpControllerState NV variable. Rename the getter functions to *FromFmpControllerState and simplify them to pure field extractors that take a required FMP_CONTROLLER_STATE pointer. Each getter extracts the field value if the state is non-NULL and the field is valid, returning a default otherwise. No getter calls GetFmpControllerState() internally. PopulateDescriptor() now calls GetFmpControllerState() once and passes the result to all getters, then frees it after the last use. This eliminates redundant NV reads when the variable exists and avoids repeated failed reads and error messages when the variable does not exist. Signed-off-by: Shubham Kumar

FmpDevicePkg: 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

FmpDevicePkg: GetImageInfo Add missing conditions

REF: UEFI spec v2.10 23.1.2 REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4660 1.For EFI_FIRMWARE_MANAGEMENT_PROTOCOL.GetImage(): Add the following sentence at the end of the Image parameter description. "May be NULL with a zero ImageSize in order to determine the size of the buffer needed". Modify the description of "EFI_INVALID_PARAMETER" return code as "The ImageSize is not too small and Image is NULL." 2.For EFI_FIRMWARE_MANAGEMENT_PROTOCOL.GetImageInfo(): Add the following sentence at the end of the ImageInfo parameter description."May be NULL with a zero ImageInfoSize in order to determine the size of the buffer needed".

FmpDevicePkg/FmpDxe: Improve handling of XDR certs

2025-09-24T00:02:41+00:00

The current implementation for XDR certificate handling assumes the PublicKeyDataXdr buffer is 4-byte aligned. This is not always the case. For example, if PublicKeyDataXdr=0x02, and the length is 0x05, the correct offset should be 0x2 + align_up(0x5, 4) -> 0x2 + 0x8 = 0xA. The current logic produces align_up(0x2 + 0x5, 4) -> align_up(0x7, 4) = 0x8. Signed-off-by: Antaeus Kleinert-Strand
