ArmVirtPkg, MdeModulePkg: Move Arm CCA Library to MdeModulePkg

2026-09-29T13:27:06+00:00

ArmCcaLib provides helper functions for detecting Realm execution state and caching Realm IPA width. These helpers build on the architectural Arm CCA RSI library and are not specific to ArmVirtPkg. Therefore, move ArmCcaLib, ArmCcaLibNull, their public header, and related GUID declarations to MdeModulePkg. Update ArmVirtPkg library mappings and consumers to use the new MdeModulePkg library instances. Also perform minor non-functional cleanup to the moved INF files by fixing a comment typo and ordering the package dependencies.

ArmVirtPkg, MdeModulePkg: Move Arm CCA RSI library to MdeModulePkg

2026-09-29T13:27:06+00:00

The Arm Confidential Compute AArchitecture (CCA) Realm Service Interface (RSI) is a standard interface that an Arm CCA Realm Guest VM can utilise to request services from the Arm CCA Realm Management Monitor (RMM). The Arm CCA Realm Service Interface is architectural Realm guest functionality rather than ArmVirt platform-specific code. Therefore, move ArmCcaRsiLib and its public header to MdeModulePkg, declare the library class there, and update ArmVirtPkg consumers to use the new library instance path.

MdeModulePkg/GptLib: Extract shareable GPT parser into a library

2026-07-20T21:50:57+00:00

As reported in CVE-2024-13745 via oss-sec, DxeTpm2MeasureBootLib can measure a partition table that differs from the one parsed by the PartitionDxe driver. To address this, the more complete GPT parsing logic from PartitionDxe is extracted into a standalone GptLib library so it can be shared between PartitionDxe and DxeTpm2MeasureBootLib. This ensures that the exact same partition table measured into PCR[5] is the one parsed and used by the system. PartitionDxe behavior is unchanged.

MdeModulePkg: Add definition for 64 bit ACPI GAS

Add a macro definition for defining ACPI Generic Address Space for QWORD memory. Signed-off-by: Varshit Pandya

MdeModulePkg: Follow pragma once coding convention

2026-06-25T19:40:31+00:00

Update recent changes in MdeModulePkg to follow the latest EDK II C Coding Standards Specification (5.3) to use '#pragma once' instead of traditional macro-based include guards in header files. https://tianocore-docs.github.io/edk2-CCodingStandardsSpecification/draft/5_source_files/53_include_files.html#53-include-files Signed-off-by: Michael Kubacki

EmbeddedPkg,MdeModulePkg,DynamicTablesPkg: Move ACPI helper macros

2026-06-18T13:03:24+00:00

Move the ACPI table helper macros from EmbeddedPkg's AcpiLib.h to MdeModulePkg's AcpiHelperMacros.h. These macros describe ACPI data initializers and do not depend on the AcpiLib library interface. Keeping them in AcpiLib.h forces users that only need the macros to include the AcpiLib library header unnecessarily. Place the macros in a common MdeModulePkg public header so ACPI table producers can include the macro definitions directly without implying use of AcpiLib. The companion edk2-platforms change is: "Global: Include AcpiHelperMacros.h for ACPI helper macros" Tested: DynamicTablesPkg: X64/AARCH64 DEBUG/RELEASE/NOOPT MdeModulePkg: X64/AARCH64 DEBUG/RELEASE/NOOPT EmbeddedPkg: X64/AARCH64 DEBUG/RELEASE/NOOPT Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Varshit Pandya

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.
