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 o= nly describe buffers that w= ill be allocated with bus_dmamem_alloc(). Al= so, due to resource sharing with other tags, this f= lag does not guarantee that resources will be allocated or reserved exclusively for this ta= g. It should be treated on= ly as a minor optimization. --=20 You are receiving this mail because: You are the assignee for the bug.=
