Revert "ArmPlatformPkg,EmbeddedPkg,MdeModulePkg: Move RealTimeClockLib ..."

2026-05-06T03:41:31+00:00

This reverts commit 57230fff6b39a665485be1bd43ec608d412ba6fb. RealTimeClockLib is not a generic library class that is intended to be used widely to get access to the RTC when the associated runtime services are not available in the calling context. The purpose of RealTimeClockLib is to abstract the underlying hardware access from the generic RealTimeClockRuntimeDxe driver, which backs the runtime services. This means it does not belong in a different package; it belongs in the same package as the driver. Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Ard Biesheuvel

MdeModulePkg: Add CxlIo.h protocol

2026-05-01T06:48:04+00:00

Create a CXL protocol for interacting with CXL endpoint devices. CXL devices are necessarily also PCI devices, so the PCI IO protocol is also provided as part of the CXL protocol. The protocol provides access to the following operations for CXL devices: - Read from a DVSEC register block - Write to a DVSEC register block - Perform DOE transaction This set of operation is sufficient to implement BIOS-level CXL functionality.

MdeModulePkg: CpuExceptionHandlerLib: Define X86_CPU_INTERRUPT_NUM

2026-03-07T03:58:40+00:00

There are currently many definitions for the number of interrupts for X86 processors. Centralize this definition in CpuExceptionHandlerLib. Signed-off-by: Oliver Smith-Denny

MdeModulePkg/Include/Guid: Add back include guard

2026-02-27T07:15:11+00:00

Add include guards back to include files that use the same include guard macro in BaseTools/Source/C/Include/Common and MdePkg or MdeModulePkg. Signed-off-by: Michael D Kinney

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: Add PcdDelayedDispatchMaxEntries

2025-09-23T01:02:04+00:00

The current fixed value of 8 for `DELAYED_DISPATCH_MAX_ENTRIES` is not large enough to accommodate platform usage. This change replaces the macro with a PCD that can be configured by platforms. In the case the default PCD value is too small, an error message explaining that the PCD should be updated will be printed followed by an assert. Signed-off-by: Michael Kubacki

ArmPlatformPkg,EmbeddedPkg,MdeModulePkg: Move RealTimeClockLib header

2025-09-08T08:54:42+00:00

RealTimeClockLib is an architectural implementation that is not restricted to the embedded segment or any platform in particular. So the header has been moved to MdeModulePkg. And the package has been added to the relevant INF files. Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Sachin Ganesh

MdeModulePkg: Support conditional UFS initialization

2025-08-08T01:06:56+00:00

Add SkipHceReenable and SkipLinkStartup flags to the EDKII_UFS_HC_PLATFORM_PROTOCOL to support using a UFS controller that has already been initialized. Signed-off-by: Bob Morgan
