From 0db2e5d18f76a66ca945447d9f610bed0a94ca5a Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Thu, 1 Oct 2015 20:13:58 +0100 Subject: iommu: Implement common IOMMU ops for DMA mapping Taking inspiration from the existing arch/arm code, break out some generic functions to interface the DMA-API to the IOMMU-API. This will do the bulk of the heavy lifting for IOMMU-backed dma-mapping. Since associating an IOVA allocator with an IOMMU domain is a fairly common need, rather than introduce yet another private structure just to do this for ourselves, extend the top-level struct iommu_domain with the notion. A simple opaque cookie allows reuse by other IOMMU API users with their various different incompatible allocator types.
