The patch series extends the existing DMA backends with missing *coherent callbacks and simplifies the generic function to basically only call the registered backend. This allows future optimizations in hardware specific IOMMU implementations. The code ist tested on AMD64 with AMD IOMMU, GART, SWIOTLB and NOMMU as well as on my old 486 box. Muli tested the Calgary specific patch. Joerg Changes since v1: - fixed wrong logic in the pci-nommu alloc_coherent code - moved dma_*_coherent to include/asm-x86/dma-mapping.h git diff --stat tip/master.. : arch/x86/kernel/amd_iommu.c | 2 - arch/x86/kernel/pci-calgary_64.c | 14 ++++ arch/x86/kernel/pci-dma.c | 146 +------------------------------------- arch/x86/kernel/pci-gart_64.c | 35 +++++++++- arch/x86/kernel/pci-nommu.c | 62 ++++++++++++++++ include/asm-x86/dma-mapping.h | 47 ++++++++++--- 6 files changed, 149 insertions(+), 157 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
