A fundamental problem with AMD IOMMUs is that the VMM must write-protect guest I/O page tables from the guest in order to intercept all guest updates and propagate the updates to the shadow I/O page tables. AMD manual says as much. Until this is implemented, I think device assignment must be disabled when AMD IOMMU is in use. > > David Kiarie (4): > hw/i386: Introduce AMD IOMMU > hw/i386: ACPI table for AMD IOMMU > hw/core: Add AMD IOMMU to machine properties > hw/pci-host: Emulate AMD IOMMU > > hw/acpi/aml-build.c | 2 +- > hw/acpi/core.c | 13 - > hw/core/machine.c | 33 +- > hw/i386/Makefile.objs | 1 + > hw/i386/acpi-build.c | 93 ++- > hw/i386/amd_iommu.c | 1426 > +++++++++++++++++++++++++++++++++++++++++ > hw/i386/amd_iommu.h | 398 ++++++++++++ > hw/pci-host/q35.c | 25 +- > include/hw/acpi/acpi-defs.h | 14 + > include/hw/acpi/acpi.h | 16 + > include/hw/acpi/aml-build.h | 1 + > include/hw/boards.h | 7 + > include/hw/i386/intel_iommu.h | 1 + > include/hw/pci/pci.h | 2 + > qemu-options.hx | 7 +- > util/qemu-config.c | 8 +- > 16 files changed, 2012 insertions(+), 35 deletions(-) > create mode 100644 hw/i386/amd_iommu.c > create mode 100644 hw/i386/amd_iommu.h > > -- > 2.1.4
