35 * In "owned" mode, a single parent owns the entire pool, and the pool owns all
37 * panfrost_pool_get_bo_handles. Freeing occurs at the level of an entire pool.
38 * This is useful for streaming uploads, where the batch owns the pool.
40 * In "unowned" mode, the pool is freestanding. It does not track created BOs
