7 swiotlb is a memory buffer allocator used by the Linux kernel DMA layer. It is
10 the DMA layer calls swiotlb to allocate a temporary memory buffer that conforms
16 Device drivers don't interact directly with swiotlb. Instead, drivers inform
31 swiotlb was originally created to handle DMA for devices with addressing
61 The primary swiotlb APIs are swiotlb_tbl_map_single() and
77 swiotlb also provides "sync" APIs that correspond to the dma_sync_*() APIs that
79 device. The swiotlb "sync" APIs cause a CPU copy of the data between the
80 original buffer and the bounce buffer. Like the dma_sync_*() APIs, the swiotlb
