  37  * Accumulated HW Queries:
  38  *
  39  * Unlike the original HW Queries in earlier adreno generations (see
  40  * freedreno_query_hw.[ch], later generations can accumulate the per-
  41  * tile results of some (a4xx) or all (a5xx+?) queries in the cmdstream.
  42  * But we still need to handle pausing/resuming the query across stage
  43  * changes (in particular when switching between batches).
  44  *
  45  * fd_acc_sample_provider:
  46  *   - one per accumulated query type, registered/implemented by gpu
  47  *     generation specific code
  48  *   - knows how to emit cmdstream to pause/resume a query instance
  49  *
  50  * fd_acc_query:
  51  *   - one instance per query object
  52  *   - each query object has it's own result buffer, which may
  53  *     span multiple batches, etc.
