| /* panfrost_bo_access is here to help us keep track of batch accesses to BOs |
| * and build a proper dependency graph such that batches can be pipelined for |
| * better GPU utilization. |
| * |
| * Each accessed BO has a corresponding entry in the ->accessed_bos hash table. |
| * A BO is either being written or read at any time (see if writer != NULL). |
| * When the last access is a write, the batch writing the BO might have read |
| * dependencies (readers that have not been executed yet and want to read the |
| * previous BO content), and when the last access is a read, all readers might |
| * depend on another batch to push its results to memory. That's what the |
| * readers/writers keep track off. |
| * There can only be one writer at any given time, if a new batch wants to |
| * write to the same BO, a dependency will be added between the new writer and |
| * the old writer (at the batch level), and panfrost_bo_access->writer will be |
| * updated to point to the new writer. |
