The in-kernel real mode IOMMU support is added by another series posted separately. As the first and main aim of this series is the POWERNV platform support, the "Enable on POWERNV platform" patch goes first and introduces an API to be used by the VFIO IOMMU driver. The "Enable on pSeries platform" patch simply registers PHBs in the IOMMU subsystem and expects the API to be present, it enables VFIO support in fully emulated QEMU guests. These patches were tested against 3.8 and the "iommu: Move initialization earlier" patch is already in 3.9 so I am including it here only for the reference. Change log: * cleanups and minor fixes * added support for pSeries * separated from in-kernel IOMMU handling series (should make it easier to get sob'ed) * signed-off-by Paul Mackerras Alexey Kardashevskiy (5): iommu: Move initialization earlier KVM: PPC: iommu: Add missing kvm_iommu_map_pages/kvm_iommu_unmap_pages powerpc/vfio: Enable on POWERNV platform powerpc/vfio: Implement IOMMU driver for VFIO powerpc/vfio: Enable on pSeries platform Documentation/vfio.txt | 63 +++++ arch/powerpc/include/asm/iommu.h | 26 ++ arch/powerpc/include/asm/kvm_host.h | 14 + arch/powerpc/kernel/iommu.c | 319 +++++++++++++++++++++++ arch/powerpc/platforms/powernv/pci-ioda.c | 1 + arch/powerpc/platforms/powernv/pci-p5ioc2.c | 5 +- arch/powerpc/platforms/powernv/pci.c | 2 + arch/powerpc/platforms/pseries/iommu.c | 4 + drivers/iommu/Kconfig | 8 + drivers/iommu/iommu.c | 2 +- drivers/vfio/Kconfig | 6 + drivers/vfio/Makefile | 1 + drivers/vfio/vfio.c | 1 + drivers/vfio/vfio_iommu_spapr_tce.c | 377 +++++++++++++++++++++++++++ include/uapi/linux/vfio.h | 34 +++ 15 files changed, 861 insertions(+), 2 deletions(-) create mode 100644 drivers/vfio/vfio_iommu_spapr_tce.c -- 1.7.10.4 -- 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/
