2012-07-24Merge tag 'iommu-updates-v3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommuLinus Torvalds1-0/+4
Pull IOMMU updates from Joerg Roedel: "The most important part of these updates is the IOMMU groups code enhancement written by Alex Williamson. It abstracts the problem that a given hardware IOMMU can't isolate any given device from any other device (e.g. 32 bit PCI devices can't usually be isolated). Devices that can't be isolated are grouped together. This code is required for the upcoming VFIO framework. Another IOMMU-API change written by me is the introduction of domain attributes. This makes it easier to handle GART-like IOMMUs with the IOMMU-API because now the start-address and the size of the domain address space can be queried. Besides that there are a few cleanups and fixes for the NVidia Tegra IOMMU drivers and the reworked init-code for the AMD IOMMU. The latter is from my patch-set to support interrupt remapping. The rest of this patch-set requires x86 changes which are not mergabe yet. So full support for interrupt remapping with AMD IOMMUs will come in a future merge window." * tag 'iommu-updates-v3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (33 commits) iommu/amd: Fix hotplug with iommu=pt iommu/amd: Add missing spin_lock initialization iommu/amd: Convert iommu initialization to state machine iommu/amd: Introduce amd_iommu_init_dma routine iommu/amd: Move unmap_flush message to amd_iommu_init_dma_ops() iommu/amd: Split enable_iommus() routine iommu/amd: Introduce early_amd_iommu_init routine iommu/amd: Move informational prinks out of iommu_enable iommu/amd: Split out PCI related parts of IOMMU initialization iommu/amd: Use acpi_get_table instead of acpi_table_parse iommu/amd: Fix sparse warnings iommu/tegra: Don't call alloc_pdir with as->lock iommu/tegra: smmu: Fix unsleepable memory allocation at alloc_pdir() iommu/tegra: smmu: Remove unnecessary sanity check at alloc_pdir() iommu/exynos: Implement DOMAIN_ATTR_GEOMETRY attribute iommu/tegra: Implement DOMAIN_ATTR_GEOMETRY attribute iommu/msm: Implement DOMAIN_ATTR_GEOMETRY attribute iommu/omap: Implement DOMAIN_ATTR_GEOMETRY attribute iommu/vt-d: Implement DOMAIN_ATTR_GEOMETRY attribute iommu/amd: Implement DOMAIN_ATTR_GEOMETRY attribute ...

2012-05-12iommu/exynos: Add iommu driver for EXYNOS PlatformsKyongHo Cho1-0/+1076
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 <mach/sysmmu.h> Signed-off-by: KyongHo Cho <pullip.cho@samsung.com> Acked-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
