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