This patchset provides the Freescale PAMU (Peripheral Access Management Unit) driver and the corresponding IOMMU API implementation. PAMU is the IOMMU present on Freescale QorIQ platforms. PAMU can authorize memory access, remap the memory address, and remap the I/O transaction type.
This set consists of the following patches: 1. Addition of new field in the device (powerpc) archdata structure for storing iommu domain information pointer. This pointer is stored when the device is attached to a particular iommu domain. 2. Add PAMU bypass enable register to the ccsr_guts structure. 3. Addition of domain attributes required by the PAMU driver IOMMU API. 4. PAMU driver and IOMMU API implementation. This patch set is based on the next branch of the iommu git tree maintained by Joerg. Varun Sethi (4): store iommu domain info in device arch data. add pamu bypass enable register to guts. Add iommu attributes for PAMU FSL PAMU driver. arch/powerpc/include/asm/device.h | 4 + arch/powerpc/include/asm/fsl_guts.h | 4 +- drivers/iommu/Kconfig | 8 + drivers/iommu/Makefile | 1 + drivers/iommu/fsl_pamu.c | 1152 +++++++++++++++++++++++++++++++++++ drivers/iommu/fsl_pamu.h | 398 ++++++++++++ drivers/iommu/fsl_pamu_domain.c | 1033 +++++++++++++++++++++++++++++++ drivers/iommu/fsl_pamu_domain.h | 96 +++ include/linux/iommu.h | 49 ++ 9 files changed, 2744 insertions(+), 1 deletions(-) create mode 100644 drivers/iommu/fsl_pamu.c create mode 100644 drivers/iommu/fsl_pamu.h create mode 100644 drivers/iommu/fsl_pamu_domain.c create mode 100644 drivers/iommu/fsl_pamu_domain.h -- 1.7.4.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
