2026-06-18EmbeddedPkg,MdeModulePkg,DynamicTablesPkg: Move ACPI helper macrosVarshitPandya1-75/+0
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 <varshit.pandya@arm.com>
2026-06-13EmbeddedPkg, OvmfPkg: Produce FV3 HOBs for Extracted FVsOliver Smith-Denny1-2/+5
EmbeddedPkg's PrePiLib and OvmfPkg's PeilessStartupLib (which uses PrePiLib) only produce FV2 HOBs for extracted FVs. However, FV3 HOBs have superceded FV2 HOBs for describing extracted FVs. This commit updates both of these libs to also produce FV3 HOBs, following PEI's pattern of producing an FV, FV2, and FV3 HOB for each extracted FV. Eventually, only FV3 HOBs will be produced, so this paves the way for that. Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Oliver Smith-Denny <osde@microsoft.com>
2026-06-13EmbeddedPkg, OvmfPkg: PrePiLib: Use Correct FvName in FV2 HOB ProductionDmitry Antipov1-18/+4
PrePiLib is incorrectly producing FV2 HOBs. The FvName field of the FV2 HOB is intended to be the parent FV's name. This way the HOB consumer phase can identify when an FV has already been extracted: if the file name of the extracted FV and the parent FV name match in the FV2 HOB. With the incorrect FvName, DXE will re-extract the already extracted FV, which can be a large performance hit (some platforms we have seen ~1 second). This requires an update to FfsProcessFvFile to pass the parent FV handle through so the FV2 HOB can be correctly produced. OvmfPkg consumers are also updated.

2026-05-06Revert "ArmPlatformPkg,EmbeddedPkg,MdeModulePkg: Move RealTimeClockLib ..."Ard Biesheuvel1-0/+120
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.

2026-02-24EmbeddedPkg: Replace include guards with #pragma onceMichael Kubacki13-52/+13
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>

2023-10-18EmbeddedPkg/RealTimeClockLib: drop LibRtcVirtualNotifyEvent from lib classLaszlo Ersek1-15/+0
The RealTimeClockLib class header in edk2 mistakenly declares a function called LibRtcVirtualNotifyEvent(). No component ever calls this function crossing module boundaries; all RealTimeClockLib instances in edk2 and edk2-platforms are supposed to register (and do register) their SetVirtualAddressMap() notification functions. At this point, the word "LibRtcVirtualNotifyEvent" no longer occurs in any of edk2, edk2-platforms, even edk2-non-osi, except the library class header proper. Remove the LibRtcVirtualNotifyEvent() function declaration. Build-tested only (with "EmbeddedPkg.dsc").

These can be used, for instance, to automate the population of an SMBIOS Type 0 BIOS Release Date when building a UEFI firmware (which is how we plan to use these macros for the Raspberry Pi platform). These macros should work for any compiler that follows ISO/IEC 9899, but we add a check for the compiler we have tested to be on the safe side. Note that we decided against adding a #error or #warn for compilers that haven't been validated, as we don't want to introduce breakage for people who may already be using the header with something else than gcc, MSVC or Clang. Instead, we expect those to send a patch that adds their compiler to the list, once they have tested the macros there.

The SPI NOR flash drivers which base on ArmPlatformPkg's NorFlashDxe usually make use of static declarations of the flash instances with their type and parameters. As a result it implies hardcoding the exact way of flash handling, not to mention the code does not look very nice. Much better solution would be obtaining the flash ID and hence its description in runtime. JEDEC compliant SPI NOR devices allow to obtain their IDs with READ_ID command (0x9f), which should return the vendor ID byte, followed by 2 to 4 following device ID bytes. Use this capability for implementing a NorFlashInfoLib that gives an access to the NOR flash description data, such as name, page size, sector (block) size and others, of more than 50 different models. The new library user should pass an output array from issuing READ_ID command to the NorFlashGetInfo () routine - if the match is found, an allocated (optionally for RT) pool with the flash description copy will be returned.
