Some of TI OMAP series have the peripheral devices with their own MMU(iommu), which is composed of its own tlb and optional h/w pagetable(twl). These MMUs don't depend on mpu(arm) mmu at all, but their algorithms are somewhat similar and they share the same physical address space. This patch provides with common in-kernel iommu APIs such OMAP peripheral devices(Camera ISP, IVA1, IVA2, DSP and the equivalent ones in the latest OMAP successors) to handle peripheral device iommus in the same manner. --- Hiroshi DOYU (6): omap2 iommu: entries for Kconfig and Makefile omap iommu: entries for Kconfig and Makefile omap iommu: simple virtual address space management omap iommu: omap3 iommu device registration omap iommu: omap2 architecture specific functions omap iommu: tlb and pagetable primitives arch/arm/include/asm/io.h | 6 arch/arm/mach-omap2/Makefile | 5 arch/arm/mach-omap2/iommu2.c | 325 +++++++++++ arch/arm/mach-omap2/omap3-iommu.c | 111 ++++ arch/arm/mm/ioremap.c | 11 arch/arm/plat-omap/Kconfig | 8 arch/arm/plat-omap/Makefile | 1 arch/arm/plat-omap/include/mach/iommu.h | 157 +++++ arch/arm/plat-omap/include/mach/iommu2.h | 94 +++ arch/arm/plat-omap/include/mach/iovmm.h | 94 +++ arch/arm/plat-omap/iommu.c | 913 ++++++++++++++++++++++++++++++ arch/arm/plat-omap/iopgtable.h | 72 ++ arch/arm/plat-omap/iovmm.c | 892 +++++++++++++++++++++++++++++ 13 files changed, 2689 insertions(+), 0 deletions(-) create mode 100644 arch/arm/mach-omap2/iommu2.c create mode 100644 arch/arm/mach-omap2/omap3-iommu.c create mode 100644 arch/arm/plat-omap/include/mach/iommu.h create mode 100644 arch/arm/plat-omap/include/mach/iommu2.h create mode 100644 arch/arm/plat-omap/include/mach/iovmm.h create mode 100644 arch/arm/plat-omap/iommu.c create mode 100644 arch/arm/plat-omap/iopgtable.h create mode 100644 arch/arm/plat-omap/iovmm.c -- Hiroshi DOYU -- 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/
