That description now reads: BUS_DMA_ALLOCNOW Pre-allocate enough resources to handle at least one map load operation on this tag. If sufficient resources are not available, ENOMEM is returned. This should not be used for tags that only describe buffers that will be allocated with bus_dmamem_alloc(). Also, due to resource sharing with other tags, this flag does not guarantee that resources will be allocated or reserved exclusively for this tag. It should be treated only as a minor optimization. -- You are receiving this mail because: You are the assignee for the bug.home | help
