DynamicTablesPkg: SsdtSerialPortFixupLib: Add GICv5 IRQ ranges to IRQ check

2026-09-15T10:12:13+00:00

To support SPCR with GicV5, check GiCv5 SPI IRQ ranges too. And cleanup for ifdef for ARM specific validation with the Arch specific function to validate serial port information. Signed-off-by: Sarah Walker

DynamicTablesPkg: 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

DynamicTablesPkg: Move Serial Port Info Objects to Arch Common

2024-07-29T13:44:55+00:00

Move Serial port info objects like the generic serial port info, Serial console port info and Serial debug port info from Arm Namespace to the Arch Common namespace. i.e. EArmObjSerialPortInfo -> EArchCommonObjSerialPortInfo EArmObjConsolePortInfo -> EArchCommonObjConsolePortInfo EArmObjSerialDebugPortInfo -> EArchCommonObjSerialDebugPortInfo CM_ARM_SERIAL_PORT_INFO -> CM_ARCH_COMMON_SERIAL_PORT_INFO Correspondingly also update the following modules to reflect the changes introduced by the move: - DBG2 Generator - SPCR Generator - SSDT Serial Port Fixup Lib - SSDT Serial Port Generator - FdtHwInfoParserLib/ArmSerialPortParser - ConfigurationManagerObjectParser - Dynamic Plat Repo TokenFixer map.

DynamicTablesPkg: SSDT Serial Port Fixup library

2020-08-13T18:00:06+00:00

According to Arm Server Base Boot Requirements, Platform Design Document version 1.2 revision D, September 2, 2019, section '4.2.1.8 SPCR'; The SPCR console device must be included in the DSDT. Additionally, it is often desirable to describe the serial ports available on a platform so that they are available for use by a rich OS. To facilitate the description of serial ports on a platform a common SSDT Serial Port Fixup library is introduced. It provides interfaces to build a SSDT serial port definition block table based on the serial port information. The SSDT Serial Port Fixup library is used by the SPCR, DBG2 and SSDT Serial Port generator to describe the serial port information in a definition block. +------------+ +------------+ +------------+ | SPCR Gen | | DBG2 Gen | | SERIAL Gen | +------------+ +------------+ +------------+ +----------------------------------+ | SSDT Serial Port Fixup library | +----------------------------------+ The SSDT Serial Port Fixup library: - Parses the SSDT Serial Port template using the AmlLib library to generate an AML tree. - Updates the _UID, _HID and _CID values. - Fixes up the Serial port base address, length and the interrupt number in the _CRS descriptor. - Fixes up the serial-port name. - Serialises the AML Tree to a buffer containing the definition block data. The definition block data is then installed by the corresponding table generator. Signed-off-by: Pierre Gondois Signed-off-by: Sami Mujawar Reviewed-by: Alexei Fedorov
