| Thread-topic: | [PATCH][retry 2] Make x86_64 swiotlb code to support dma_ops [1/2] |
As per Keir's and Jan's suggestions, I'm simplifying my approach to getting GART into the kernel. This patch set makes the x86_64 swiotlb code work with dma_ops. The first patch creates the arch/x86_64/kernel/pci-dma-xen.c file based on the standard pci-dma.c. The second patch modifies arch/x86_64/kernel/pci-swiotlb-xen.c to work with dma_ops, and modifies arch/x86_64/kernel/pci-dma-xen.c slightly to be Xen-safe by copying over some functions from arch/i386/kernel/pci-dma-xen.c Signed-off-by: Mark Langsdorf <mark.langsdorf@xxxxxxx> -Mark Langsdorf AMD, Inc.
