...damentally wrong. The DMA API does a few different things: a) address translation This does include IOMMUs. But it also includes random offsets between PCI bars and system memory that we see on various platforms. Worse so some of these offsets might be based on banks, e.g. on the broadcom bmips platform. It also deals with bitmask in physical addresses related to memory encryption like AMD SEV. I'd be really curious how for example the Intel virtio based NIC is going to work on any of those plaforms. b) coherency On many architectures DMA is not cache coherent, and we need...

...A addresses it is completely related to DMA. For some examples take a look at: arch/x86/pci/sta2x11-fixup.c arch/mips/include/asm/mach-ath25/dma-coherence.h or anything setting dma_pfn_offset. > > Worse so some of these offsets might be based on > > banks, e.g. on the broadcom bmips platform.
