MdeModulePkg: Update UI strings to indicate case-insensitive key options

2026-09-15T03:00:02+00:00

Update the prompt strings for save/exit and confirm actions to show both uppercase and lowercase key options (e.g., 'Y(y)' and 'N(n)') to make it clear that the system accepts either case. This improves user experience by avoiding confusion about case sensitivity. Affected strings: - ARE_YOU_SURE (CustomizedDisplayLib) - CONFIRM_OPTION (DisplayEngineDxe) - RECONNECT_CHANGES_OPTIONS (DisplayEngineDxe) French translations are updated accordingly.

MdeModulePkg: Enhance the handling of registering hot key

2026-05-27T03:45:48+00:00

It's not a proper approach when dealing the return string of HiiGetString function with ASSERT on REALEASE or NOOPT mode. This patch add a check for NewString before calling RegisterHotKey() for the case. Signed-off-by: Qihang Gao

MdeModulePkg: 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

MdeModulePkg: Fix regressions from 11687, 11689.

2025-12-19T06:48:19+00:00

11687 introduced a null check and break on the orderedlist carriage return input handler. The carriage return is a special case that should result in exiting the menu, but the null check that prevented null pointer access changed the logic to continue in the input wait loop. Removed the break while still preventing null variable access and allow function to exit. 11689 introduced checks on the call to EfiBootManagerGetLoadOptions, but this encounterd a problem with the way that a default platform recovery option was created. The default platform recovery option was attempting to go through existing recovery options to get the next available recovery option number. The introduced null check short circuited these additional calls and resulted in the platform recovery option not being created. Modified the logic to no longer attempt to access recovery options when non exist, and still create the default platform recovery option. Signed-off-by: Aaron Pop

MdeModulePkg: Fix regressions from 11686, 11687, 11688, 11689.

11686, 11687, 11688, 11689 included some inverted conditionals during the refactor. While the system booted, some behavior was incorrect based on the inverted conditionals. Signed-off-by: Aaron Pop
