DynamicTablesPkg: Add helper to add CmObj with given token

2025-10-13T10:45:45+00:00

Implement function to add a CmObj with a token provided by the caller. This is intended to be used with abstract tokens, the value of which is generated by the caller. Signed-off-by: Sarah Walker

DynamicTablesPkg: Add SmbiosSmcLib

2025-09-30T08:27:48+00:00

Implement a support library for SMBIOS-related SMC calls. Currently this implements a function to return the SoC ID. Signed-off-by: Sarah Walker

DynamicTablesPkg: add Tpm2DeviceTableLib to generate Tpm2 device table

2025-07-29T08:07:39+00:00

Introduce Tpm2DeviceTableLib to generate SSDT table which describes Tpm2 devices. This dynamic table generation is controlled by PcdGenTpm2DeviceTable which default value is FALSE. When it is TRUE, the TPM2 device ssdt table is generated when TPM2 ACPI table is generated. Signed-off-by: Yeoreum Yun

DynamicTablesPkg: Add GetProximityDomainId() to CmObjHelperLib

2025-06-11T12:24:35+00:00

Proximity domains Ids should now be described using the CM_ARCH_COMMON_PROXIMITY_DOMAIN_INFO object. This adds a level of indirection: a Token allows to retrieve a CM_ARCH_COMMON_PROXIMITY_DOMAIN_INFO object, and this object might either have a hard-coded Id, or rely on the MetadataObjLib to generate an Id. Add a GetProximityDomainId () function to the CmObjHelperLib to factorize this level of abstraction and allow other generators to re-use the logic. Signed-off-by: Pierre Gondois

DynamicTablesPkg: Add CmObjHelperLib

2025-06-11T12:24:35+00:00

Some generators share some logic in how they handle CmObj. In an effort to factorize this code, create a CmObjHelperLib, aiming to host the common CmObj manipulation logic. Start by adding a CheckAcpiTablePresent() function, allowing to check if an ACPI table is in the list of the tables to install. Signed-off-by: Pierre Gondois

DynamicTablesPkg: Add MetadataHandlerLib library

2025-06-11T12:24:35+00:00

Built on top of the MetadataObjLib, this library aims to provide functions for each METADATA_ID to: - Generate new Metadata on the fly: the caller provides minimal information for a METADATA_ID, and the library generates the missing information. - Validate all the Metadata objects for a METADATA_ID. For instance, _UID must be unique for a _HID/_CID/EISAID. This patch also adds support for generation/validation of: - UIDs: For each EISAID or NameId, UIDs must be unique. The generation if UIDs is done by a per-EISAID/NameId incrementing counter. The validation of the Metadata consists in checking for the uniqueness of the UID per EISAID/NameId. - ProximityDomains: Proximity Domain Ids are generated by a counter, starting from 0. The validation of the Metadata consists in checking for the uniqueness of the proximity domain Ids. Signed-off-by: Pierre Gondois

DynamicTablesPkg: Add MetaDataObjLib library

2025-06-11T12:24:35+00:00

The DynamicTablesPkg allows to generate firmware tables based on information provided by a user or another source of information (a device tree for instance). Some information might be implicitly generated by generators. For instance, for ACPI tables, AML names or Uids are created by generators, but not provided by the user or another source of information. Some generators might need to cross-reference object/generated data that was previous generated for an object by another generator. For instance, there are three different generators creating serial ports in the AML namespace. These 3 generators must ensure not to use an Id which was not already created by another generator. Another example would be a generator needing to reference the AML path of a serial port. As the AML path is dynamically generated, this is currently not possible to do. Add a MetaDataObjLib library to keep track of the meta-data previously generated for an object. Signed-off-by: Pierre Gondois

DynamicTablesPkg/AmlLib: Implement C-State and P-State ACPI object

2025-02-25T09:52:23+00:00

This commit introduces a set of functions designed to facilitate the creation and management of C-State (_CST, _CSD) and P-State (_PCT, _PSS) ACPI objects. Detailed Summary: 1) AmlCreateCstNode(): This function is responsible for creating a _CST (C-State) node, which is essential for defining processor idle states. 2) AmlAddCstState(): This function adds a C-State package to an existing CST node, allowing for the specification of individual C-State entries. 3) AmlCreateCsdNode(): This function creates a _CSD (C-State Dependency) node, which is used to describe dependencies between different C-States. 4) AmlCreatePctNode(): This function generates a _PCT (Performance Control) node, complete with PCT packages, to manage performance state transitions. 5) AmlCreatePssNode(): This function creates a _PSS (Performance Supported States) node, which lists the supported performance states for a processor.
