"[PATCH] x86_64: Use function pointers to call DMA mapping functions\n\nAK: I hacked Muli\u0027s original patch a lot and there were a lot\nof changes - all bugs are probably to blame on me now.\nThere were also some changes in the fall back behaviour\nfor swiotlb - in particular it doesn\u0027t try to use GFP_DMA\nnow anymore. Also all DMA mapping operations use the\nsame core dma_alloc_coherent code with proper fallbacks now.\nAnd various other changes and cleanups.\n\nKnown problems: iommu\u003dforce swiotlb\u003dforce together breaks\n needs more testing.\n\nThis patch cleans up x86_64\u0027s DMA mapping dispatching code. Right now\nwe have three possible IOMMU types: AGP GART, swiotlb and nommu, and\nin the future we will also have Xen\u0027s x86_64 swiotlb and other HW\nIOMMUs for x86_64. In order to support all of them cleanly, this\npatch:\n\n- introduces a struct dma_mapping_ops with function pointers for each\n of the DMA mapping operations of gart (AMD HW IOMMU), swiotlb\n (software IOMMU) and nommu (no IOMMU).\n\n- gets rid of:\n\n if (swiotlb)\n return swiotlb_xxx();\n\n- PCI_DMA_BUS_IS_PHYS is now checked against the dma_ops being set\nThis makes swiotlb faster by avoiding double copying in some cases.\n\nSigned-Off-By: Muli Ben-Yehuda \u003cmulix@mulix.org\u003e\nSigned-Off-By: Jon D.
