  -- == Description
  --
  -- This extension allows applications to insert markers in the command
  -- stream and associate them with custom data.
  --
  -- If a device lost error occurs, the application /may/ then query the
  -- implementation for the last markers to cross specific
  -- implementation-defined pipeline stages, in order to narrow down which
  -- commands were executing at the time and might have caused the failure.
  --
  -- == New Commands

  --
  -- -   'getQueueCheckpointDataNV'

  -- == New Structures
