DynamicTablesPkg/HwInfoParser: Add cache topology parser

2026-09-30T03:29:05+00:00

Add a ParseCacheInfo() function, parsing CPU cache information from Device Tree and creating CM_ARCH_COMMON_CACHE_INFO objects. Parse: - L1 cache information directly from CPU cache properties - shared caches from "next-level-cache" DT nodes Track cache sharing through CPU masks and attach cache references to the deepest matching processor hierarchy node. The processor hierarchy objects must be added after the cache information is parsed as cache references are stored in ProcHierarchy objects. Signed-off-by: Pierre Gondois

DynamicTablesPkg/HwInfoParser: Add topology parser

2026-09-30T03:29:05+00:00

Add a TopologyInfoParser() function, parsing the "/cpus" node and the optional "cpu-map" hierarchy to create CM_ARCH_COMMON_PROC_HIERARCHY_INFO objects. When no "cpu-map" node is present, create a flat topology with a single package node containing all CPUs. Add the corresponding FDT HwInfo object identifier and hook the new parser in ArmFdtHwInfoParser. The parser must be called after the GIC parsers as leaf topology nodes point to GicC objects.

DynamicTablesPkg/HwInfoParser: Assign CPU tokens to GICC objects

2026-09-30T03:29:05+00:00

Create Tokens identifying Gic CPU interfaces. The Configuration Manager relies on PROC_HIERARCHY_INFO structures to represent the CPU topology. These objects have fields: - ParentToken: Token identifying the parent of this struct - AcpiIdObjectToken: Token identifying a Gic CPU interface (for arm) The Gic CPU interface information and topology information will be parsed in 2 different files. The same token will have to be generated for: - a GicC object - the ProcHierarchy object pointing to this GicC object Also add missing documentation in CpusNodeParser() and add a CM_ABSTRACT_TOKEN_ID_MASK macro.

DynamicTablesPkg: Extract token definitions to AbstractToken.h

2026-09-30T03:29:05+00:00

Move the Abstract Token related definitions to a separate file in prevision of the addition of new definitions. No functional change. Signed-off-by: Pierre Gondois
