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