Hi, This patchset adds support for iommu_ops for Tegra20/30. They are not expected to be merged now since it requres some other components for more testing but are posted for review. This was simply tested with the DMA API without real buffer access from device side, only with allocation/mapping/freeing from MPU side. This was originally developed with Tegra specific IOMMU API in: git://nv-tegra.nvidia.com/linux-2.6.git. v1: https://lkml.org/lkml/2011/11/17/111 Hiroshi DOYU (2): [RFC] ARM: IOMMU: Tegra20: iommu_ops for GART driver [RFC] ARM: IOMMU: Tegra30: iommu_ops for SMMU driver arch/arm/mach-tegra/include/mach/smmu.h | 63 ++ drivers/iommu/Kconfig | 22 + drivers/iommu/Makefile | 2 + drivers/iommu/tegra-gart.c | 451 ++++++++++++++ drivers/iommu/tegra-smmu.c | 1027 +++++++++++++++++++++++++++++++ 5 files changed, 1565 insertions(+), 0 deletions(-) create mode 100644 arch/arm/mach-tegra/include/mach/smmu.h create mode 100644 drivers/iommu/tegra-gart.c create mode 100644 drivers/iommu/tegra-smmu.c -- 1.7.5.4 -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
