AMDGPU Glossary
===============

Here you can find some generic acronyms used in the amdgpu driver. Notice that
we have a dedicated glossary for Display Core at
'Documentation/gpu/amdgpu/display/dc-glossary.rst'.

.. glossary::

    active_cu_number
      The number of CUs that are active on the system.  The number of active
      CUs may be less than SE * SH * CU depending on the board configuration.

    BACO
      Bus Alive, Chip Off

    BOCO
      Bus Off, Chip Off

    CE
      Constant Engine

    CIK
      Sea Islands

    CB
      Color Buffer

    CP
      Command Processor

    CPC
      Command Processor Compute

    CPF
      Command Processor Fetch

    CPG
      Command Processor Graphics

    CPLIB
      Content Protection Library

    CS
      Command Submission

    CSB
      Clear State Indirect Buffer

    CU
      Compute Unit

    DB
      Depth Buffer

    DFS
      Digital Frequency Synthesizer

    ECP
      Enhanced Content Protection

    EOP
      End Of Pipe/Pipeline

    FLR
      Function Level Reset

    GART
      Graphics Address Remapping Table.  This is the name we use for the GPUVM

Annotation

• Atlas domain: Support Tooling And Documentation / Documentation.
• Implementation status: atlas-only.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
