DynamicTablesPkg/FdtHwInfoParserLib: Update SmmuV3 DeviceId Valid flag

2026-04-20T13:25:34+00:00

SmmuV3 nodes with revision 5 have a flag with a "DeviceID mapping index valid" bit: "Set to 1 if the DeviceID mapping index field is valid. Set to 0. otherwise". Set this flag if the DeviceId mapping field has been populated. Signed-off-by: Pierre Gondois

DynamicTablesPkg: handle missing 'iommu-map' in root complex parser

2026-04-03T00:17:05+00:00

Some guests (e.g. kvmtool) do not provide a SMMU, so the PCI node in the DTB lacks an 'iommu-map'. The current code ASSERTs during boot with: "ASSERT [ConfigurationManagerDxe] RootComplexParser.c(244): (Data != ((void *) 0)) && ((DataSize % (4 * sizeof (UINT32))) == 0)" Instead, return EFI_NOT_FOUND when 'iommu-map' is absent so firmware boot can proceed.

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/FdtHwInfoParserLib/Serial: RISC-V: Convert to GSI

2025-12-02T20:52:41+00:00

In RISC-V, the GSI space is spread across multiple PLICs/APLICs. Hence, any device's IRQ number in the FDT should be appropriately converted to a GSI number based on its parent interrupt controller. Do this for UART parsing in RISC-V. Signed-off-by: Sunil V L

DynamicTablesPkg/FdtHwInfoParserLib/Pci: Convert IRQ to GSI for RISC-V

2025-12-02T20:52:41+00:00

On RISC-V platforms, the Global System Interrupt (GSI) space is divided across multiple PLIC/APLIC interrupt controllers. The IRQ number in the device tree (DT) needs to be translated to the corresponding GSI by: 1. Mapping the IRQ number to its parent interrupt controller using the phandle from the 'interrupt-map' property. 2. Converting the IRQ to a GSI number using the interrupt controller’s GSI base. This change ensures accurate IRQ-to-GSI translation for PCI devices, enabling correct interrupt routing on RISC-V systems. Signed-off-by: Sunil V L

DynamicTablesPkg/FdtHwInfoParserLib: Detect IRQ type based on IntcCells

2025-12-02T20:52:41+00:00

For some architectures and interrupt controllers, such as RISC-V’s PLIC, the PCI interrupt map does not include an explicit IRQ type. Update the parser to set the IRQ type to 0 when the interrupt controller’s 'interrupt-cells' property has a count of 1 or less, indicating no IRQ type information is provided. This change improves compatibility with RISC-V and similar platforms. Signed-off-by: Sunil V L

DynamicTablesPkg/FdtHwInfoParserLib: Add RISC-V FDT parsers

2025-12-02T20:52:41+00:00

Add FDT parsers for RISC-V that extract hardware information from the Flattened Device Tree (FDT) and create corresponding Configuration Manager (CM) objects. These CM objects provide the necessary data for ACPI table generators, such as MADT, RHCT, and SSDT, to construct RISC-V-specific tables. Signed-off-by: Sunil V L
