Request VFIO inclusion in linux-next

Hi, VFIO has been kicking around for well over a year now and has been posted numerous times for review. The pre-requirements are finally available in linux-next (or will be in the 20120626 build) so I'd like to request a new branch be included in linux-next with a goal of being accepted into v3.

atomic context for iommu_map call

Hello. It is not clear from the documentation if iommu_map()/iommu_unmap() functions may be called from atomic context. In case of Intel IOMMU, it works; in case of AMD IOMMU, it does not. Was it done by purpose? May I propose a patch for AMD IOMMU replacing GFP_KERNEL by GFP_ATOMIC to make thin

[v3 2/5] iommu/tegra: smmu: Add device tree support for SMMU

From: Hiroshi Doyu The necessary info is expected to pass from DT. For more precise resource reservation, there shouldn't be any overlapping of register range between SMMU and MC. SMMU register offset needs to be calculated correctly, based on its register bank. Signed-off-by: Hiroshi DOYU Ack

[v3 1/5] iommu: Add DMA window parser, of_get_dma_window()

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 no

[PATCH] iommu/amd: Initialize dma_ops for hotplug and sriov devices

When a device is added to the system at runtime the AMD IOMMU driver initializes the necessary data structures to handle translation for it. But it forgets to change the per-device dma_ops to point to the AMD IOMMU driver. So mapping actually never happens and all DMA accesses end in an IO_PAGE_FAU
