Detailed Description

A structure for indexing CM objects (nodes) used in PPTT generation.

PPTT_NODE_INDEXER is a wrapper around CM objects which augments these objects with additional information that enables generating PPTT structures with correct cross-references.

PPTT_NODE_INDEXER keeps track of each structure's offset from the base address of the generated table. It also caches certain information and makes PPTT cyclic reference detection possible.

Field Documentation

◆ CycleDetectionStamp

UINT32 PpttNodeIndexer::CycleDetectionStamp

Field used to mark nodes as 'visited' when detecting cycles in processor and cache topology

Definition at line 157 of file PpttGenerator.h.

◆ Object

VOID* PpttNodeIndexer::Object

Pointer to the CM object being indexed.

Definition at line 151 of file PpttGenerator.h.

◆ Offset

UINT32 PpttNodeIndexer::Offset

Offset from the start of the PPTT table to the PPTT structure which is represented by Object

Definition at line 154 of file PpttGenerator.h.

◆ Token

CM_OBJECT_TOKEN PpttNodeIndexer::Token

Unique identifier for the node.

Definition at line 149 of file PpttGenerator.h.

◆ TopologyParent

struct PpttNodeIndexer* PpttNodeIndexer::TopologyParent

Reference to a Node Indexer element which is the parent of this Node Indexer element in the processor and cache topology e.g For a hardware thread the TopologyParent would point to a CPU node For a L1 cache the TopologyParent would point to a L2 cache
