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: Remove ARM32 Support

edk2 is dropping support for the ARM32 architecture. This commit removes ARM32 support from MdeModulePkg. This also drops irrelevant VALID_ARCHITECTURE comments from infs that are not arch specific. Signed-off-by: Oliver Smith-Denny

MdeModulePkg: SataControllerSupported checks DevicePath Protocol

2024-11-01T01:53:53+00:00

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=4858 Ph52a PCIE to SATA card inserted on Intel MTL/ARL causes system hanged. Root cause of this issue is because Ph52a's driver only uses DevicePath protocol alone and EDK2 driver only uses PciIo protocol alone. Both drivers start and try to manage SATA controller.

MdeModulePkg/SataControllerDxe: Fix up ASSERTS (Private != NULL)

2023-06-01T18:08:33+00:00

ASSERT (Private != NULL) (where Private = CR(...)) is ineffective as CR(Ptr, Type, Member, Sig) either returns Ptr - offsetof(Type, Member), or ASSERTS on the signature, so it's unlikely to ever return NULL (must be passed a pointer = member's offset, or in this case, 0x4). ASSERT on This != NULL instead. Signed-off-by: Pedro Falcato Reviewed-by: Laszlo Ersek Reviewed-by: Hao A Wu

MdeModulePkg/SataControllerDxe: Log expected errors at DEBUG_INFO level

2023-06-01T18:08:33+00:00

When a UEFI_DRIVER attempts to open a protocol interface with BY_DRIVER attribute that it already has open with BY_DRIVER attribute, OpenProtocol() returns EFI_ALREADY_STARTED. This is not an error. The UEFI-2.7 spec currently says, > EFI_ALREADY_STARTED -- Attributes is BY_DRIVER and there is an item on > the open list with an attribute of BY_DRIVER > whose agent handle is the same as AgentHandle. Downgrade the log mask for this one condition to DEBUG_INFO, in SataControllerStart(). This will match the log mask of the other two informative messages in this function.
