DynamicTablesPkg: AcpiIortLibArm: Support SMMUv3 revision 5

2026-04-28T09:03:21+00:00

This change modified the SMMUv3 node logic to add a specific condition for revision 05 and a default branch for setting revision 5. It also adds a validity check for the IORT references when device ID valid bit is set in the flag. Co-authored-by: Ronny Hansen Signed-off-by: Kun Qin

DynamicTablesPkg: AcpiIortLibArm: Support IORT revision 6

2026-04-28T09:03:21+00:00

This change updated the ACPI IORT generator’s supported revision from `EFI_ACPI_IO_REMAPPING_TABLE_REVISION_05` to `EFI_ACPI_IO_REMAPPING_TABLE_REVISION_06`. Signed-off-by: Kun Qin

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: add SSDT DMC620 PMU table generator

2026-01-16T10:35:45+00:00

The Generic ACPI for Arm Components 1.2 Platform Design Document [1], section 2.6.1.2 "ASL reference code for the DMC620 PMU" provides information to describe the Arm Corelink DMC620 Dynamic Memory Controller's Performance Monitoring Unit (PMU) block using an ASL definition block table. Add support for a table generator for the DMC620 PMU block. The table generator uses the Configuration Manager protocol to obtain the following information. - Number of sockets on the platform - DMC620 devices per socket After obtaining the socket based topology, information is obtained on individual DMC620 devices. This includes - PMU register base address and length - Information on the associated PMU interrupt The table generator uses the Dynamic AML CodeGen API's for generating the table from the information obtained through the Configuration Manager protocol.

DynamicTablesPkg/RISC-V: Add AcpiSsdtPlicAplicLib library

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

Add AcpiSsdtPlicAplicLib to create PLIC and APLIC device entries in the RISC-V namespace. These interrupt controller devices are essential for accurate ACPI namespace representation on RISC-V platforms. This library facilitates SSDT generation for PLIC and APLIC, enabling proper OS discovery and configuration. Signed-off-by: Sunil V L

DynamicTablesPkg/Acpi: Add RHCT generator for RISC-V

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

Add a generator for the RISC-V Hart Capabilities Table (RHCT), a new ACPI table used to convey CPU feature information to the operating system. This generator enables firmware to describe RISC-V hart capabilities in a standardized way as part of the ACPI table set. Signed-off-by: Sunil V L

DynamicTablesPkg/Acpi: Add MADT generator for RISC-V

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

Add a MADT (Multiple APIC Description Table) generator implementation for RISC-V. RISC-V platforms may use one or more of the following interrupt controllers: RINTC, IMSIC, PLIC, and APLIC. This generator constructs the appropriate MADT entries for the supported controllers and enables MADT generation for RISC-V platforms. Signed-off-by: Sunil V L
