37 * Accumulated HW Queries:
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).
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
51 * - one instance per query object
52 * - each query object has it's own result buffer, which may
53 * span multiple batches, etc.
