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