iommu: Add DMA window parser, of_get_dma_window()

2012-06-25T11:50:28+00:00

This code was based on:
    "arch/microblaze/kernel/prom_parse.c"
    "arch/powerpc/kernel/prom_parse.c"

Can replace "of_parse_dma_window()" in the above. This supports
different formats flexibly. "prefix" can be configured if any. "busno"
and "index" are optionally specified. Set NULL and 0 if not used.

Pull arm-soc driver specific updates from Olof Johansson:
 "These changes are specific to some driver that may be used by multiple
  boards or socs.  The most significant change in here is the move of
  the samsung iommu code from a platform specific in-kernel interface to
  the generic iommu subsystem."

iommu/exynos: Add iommu driver for EXYNOS Platforms

2012-05-11T20:56:09+00:00

This is the System MMU driver and IOMMU API implementation for
EXYNOS SoC platforms. EXYNOS platforms has more than 10 System
MMUs dedicated for each multimedia accelerators.

The System MMU driver is already in arc/arm/plat-s5p but it is
moved to drivers/iommu due to Ohad Ben-Cohen gathered IOMMU
drivers there.

Any device driver in EXYNOS platforms that needs to control its
System MMU must call platform_set_sysmmu() to inform System MMU
driver who will control it. platform_set_sysmmu() is defined in

iommu/vt-d: Make intr-remapping initialization generic

2012-05-07T12:34:59+00:00

This patch introduces irq_remap_ops to hold implementation
specific function pointer to handle interrupt remapping. As
the first part the initialization functions for VT-d are
converted to these ops.

iommu: Rename intr_remapping files to intel_intr_remapping

2012-05-07T12:34:58+00:00

The files contain code mostly relevant for the Intel
implementation of interrupt remapping. Make that visible in
the file names. Also inline intr_remapping.h into
intr_remapping.c because it is only included there and the
content is very small. So there is no reason for a seperate
header file.

ARM: IOMMU: Tegra30: Add iommu_ops for SMMU driver

2012-01-26T12:59:02+00:00

Tegra 30 IOMMU H/W, SMMU (System Memory Management Unit). This patch
implements struct iommu_ops for SMMU for the upper IOMMU API.

This H/W module supports multiple virtual address spaces(domain x4),
and manages 2 level H/W translation pagetable.

Tegra 20 IOMMU H/W, GART (Graphics Address Relocation Table). This
patch implements struct iommu_ops for GART for the upper IOMMU API.

This H/W module supports only single virtual address space(domain),
and manages a single level 1-to-1 mapping H/W translation page table.

iommu/amd: Add driver stub for AMD IOMMUv2 support

2011-12-12T14:19:07+00:00

Add a Kconfig option for the optional driver. Since it is
optional it can be compiled as a module and will only be
loaded when required by another driver.
