MdePkg: Add constants for HMAT structures' fields

2026-07-06T07:39:54+00:00

Add constants for HMAT table's SSLBI and ProximityDoman structures to industry standards headers for Acpi 6.4, 6.5, and 6.6. Co-authored-by: Sophia Wang Signed-off-by: Oleksandr Tymoshenko

DynamicTablesPkg: Fix memory leak in MetaDataObjLib library

2026-07-06T07:39:54+00:00

Clean up all metadata entries when freeing a metadata handle in MetadataFreeHandle. Signed-off-by: Oleksandr Tymoshenko

ShellPkg/AcpiView: Add parser for CCEL ACPI table

2026-07-03T12:24:39+00:00

The ACPI 6.5 specification introduces the CCEL (CC Event Log) table in section 5.2.34: https://uefi.org/specs/ACPI/6.5/ 05_ACPI_Software_Programming_Model.html#cc-event-log-acpi-table Extend AcpiView with a parser to decode and display CCEL table contents. This allows users to inspect CCEL tables from the UEFI Shell. Signed-off-by: Sami Mujawar

ShellPkg/Acpiview: Make reserved-field validation common

2026-07-03T12:24:39+00:00

Move the reserved-field validators from MpamParser.c into AcpiParser.c and expose them through AcpiParser.h so they can be reused by multiple Acpiview parsers. Update the AGDI, MPAM and WSMT parsers to use the common helpers for byte-length and bit-length reserved fields. Signed-off-by: Sami Mujawar

ShellPkg/Acpiview: Increase the max supported parsers

2026-07-03T12:24:39+00:00

The RegisterParser() function is failing with error code EFI_OUT_OF_RESOURCES as we have run out of space for registering the ACPI table parsers in mTableParserList[]. Therefore, increase the MAX_ACPI_TABLE_PARSERS to 128. Signed-off-by: Sami Mujawar

DynamicTablesPkg: Smbios Memory Device Mapped Address (Type 20)

2026-07-03T10:54:53+00:00

Add an SMBIOS Type 20 generator for Memory Device Mapped Address structures. The generator builds one Type 20 table per Memory Device Mapped Address CM object, validates the address range, encodes extended addresses when the 32-bit address fields cannot represent the range, and maps optional Type 17 and Type 19 CM object references to SMBIOS handles. If either reference token is CM_NULL_TOKEN, the corresponding SMBIOS handle is set to SMBIOS_HANDLE_INVALID. Signed-off-by: Varshit Pandya

MdePkg: Add SHA-256 and SHA-512 measurement hash algorithm IDs

2026-07-03T09:26:33+00:00

The CCEL (CC Event Log) ACPI table records measurement logs for confidential computing platforms. Each measurement specifies the hash algorithm used, identified by a numeric constant. The edk2 Code First proposal "[Code First] Add supporting details of Arm Confidential Compute Architecture in UEFI spec" (#11383) https://github.com/tianocore/edk2/issues/11383 extends section 38.2 EFI_CC_MEASUREMENT_PROTOCOL to define algorithm IDs for: - SHA-256 (EFI_CC_BOOT_HASH_ALG_SHA256) - SHA-512 (EFI_CC_BOOT_HASH_ALG_SHA512) This enables CC types such as Arm CCA to record and interpret measurements using these hash algorithms. Add these definitions to the CC measurement header file to align with the updated specification. Signed-off-by: Sami Mujawar

MdePkg: Define CC Measurement register to Arm CCA REM mapping

2026-07-03T09:26:33+00:00

The edk2 Code First proposal "[Code First] Add supporting details of Arm Confidential Compute Architecture in UEFI spec" (#11383) https://github.com/tianocore/edk2/issues/11383 introduces a new section 38.4.3 'Arm Confidential Compute Architecture Extension' that defines the mapping between the TPM PCR indices, the CC event log measurement registers and the corresponding Arm CCA measurement registers where: - RIM means Realm Initial Measurement Register and - REM means Realm Extensible Measurement Register. TPM PCR Index | CC Measurement | Arm CCA-measurement | | Register Index | register | ------------------------------------------------------- 0 | 0 | RIM | 1, 7 | 1 | REM[0] | 2~6 | 2 | REM[1] | 8~15 | 3 | REM[2] | Therefore, add these definitions to the CC measurement header file to align with the updated specification.
