[RFC V2] virtio: Add platform specific DMA API translation for virito devices
...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...

I don't think you mean bars. That's unrelated to DMA.

[RFC V2] virtio: Add platform specific DMA API translation for virito devices
...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.
