* Accumulated HW Queries:
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).
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
50
* - one instance per query object
51
* - each query object has it's own result buffer, which may
52
* span multiple batches, etc.
