2026-02-24EmulatorPkg: Replace include guards with #pragma onceMichael Kubacki15-60/+15
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>
2025-07-08EmulatorPkg: Remove UGA supportGuoMinJ2-18/+18
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.

2024-01-05Add EFI_STATUS return to EMU_THUNK_PROTOCOL.SetTime()Nate DeSimone1-2/+3
There is an inconsistency between the UNIX and Windows implementations of EMU_THUNK_PROTOCOL.SetTime(). The Windows version returns an EFI_STATUS value whereas the the UNIX implementation is VOID. However, the UNIX implementation is an unimplemented stub whereas the Windows version is implementated. The current EMU_THUNK_PROTOCOL function pointer definition specifies a VOID return type. However, EMU_THUNK_PROTOCOL.SetTime() is close to the spec defined gRT->SetTime() except for missing the EFI_STATUS return type. Therefore, I conclude that the most sensible reconciliation is to add the EFI_STATUS return type to the protocol definition.
