114 A key device DMA setting is "min_align_mask", which is a power of 2 minus 1116 allocations ensure these min_align_mask bits of the physical address of the118 min_align_mask is non-zero, it may produce an "alignment offset" in the address124 swiotlb, max_sectors_kb will be 256 KiB. When min_align_mask is non-zero,130 bounce buffer might start at a larger address if min_align_mask is non-zero.
