This version includes various fixes posted separately to v7, mainly related to incorrect io address space bitmap setup and a major issue with broken mmap for memory which comes from dma_declare_coherent(). The patches have been also rebased onto Linux v3.4-rc2 which comes with dma_map_ops related changes. The code has been tested on Samsung Exynos4 'UniversalC210' and NURI boards with IOMMU driver posted by KyongHo Cho, I will put separate branch which shows how to integrate this driver with this patchset. The patches are also available on my git repository at: git://git.linaro.org/people/mszyprowski/linux-dma-mapping.git 3.4-rc2-arm-dma-v8 History of the development: v1: (initial version of the DMA-mapping redesign patches): http://www.spinics.net/lists/linux-mm/msg21241.html v2: http://lists.linaro.org/pipermail/linaro-mm-sig/2011-September/000571.html http://lists.linaro.org/pipermail/linaro-mm-sig/2011-September/000577.html v3: http://www.spinics.net/lists/linux-mm/msg25490.html v4 and v5: http://www.spinics.net/lists/arm-kernel/msg151147.html http://www.spinics.net/lists/arm-kernel/msg154889.html v6: http://www.spinics.net/lists/linux-mm/msg29903.html v7: http://www.spinics.net/lists/arm-kernel/msg162149.html Best regards Marek Szyprowski Samsung Poland R&D Center Patch summary: Marek Szyprowski (10): common: add dma_mmap_from_coherent() function ARM: dma-mapping: use pr_* instread of printk ARM: dma-mapping: introduce ARM_DMA_ERROR constant ARM: dma-mapping: remove offset parameter to prepare for generic dma_ops ARM: dma-mapping: use asm-generic/dma-mapping-common.h ARM: dma-mapping: implement dma sg methods on top of any generic dma ops ARM: dma-mapping: move all dma bounce code to separate dma ops structure ARM: dma-mapping: remove redundant code and cleanup ARM: dma-mapping: use alloc, mmap, free from dma_ops ARM: dma-mapping: add support for IOMMU mapper arch/arm/Kconfig | 9 + arch/arm/common/dmabounce.c | 84 +++- arch/arm/include/asm/device.h | 4 + arch/arm/include/asm/dma-iommu.h | 34 ++ arch/arm/include/asm/dma-mapping.h | 407 ++++----------- arch/arm/mm/dma-mapping.c | 1019 ++++++++++++++++++++++++++++++------ arch/arm/mm/vmregion.h | 2 +- drivers/base/dma-coherent.c | 42 ++ include/asm-generic/dma-coherent.h | 4 +- 9 files changed, 1138 insertions(+), 467 deletions(-) create mode 100644 arch/arm/include/asm/dma-iommu.h -- 1.7.1.569.g6f426 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
