Currently, irrespectively of the target platform, both AMD and Intel iommu drivers are built. This is the case because the existent Kconfig infrastructure does not provide any facilities for finer-grained configuration. The series adds two new Kconfig options, AMD_IOMMU and INTEL_IOMMU, that can be used to generate a tailored iommu configuration for a given platform. This version of the series is rebased on top of the current staging and addresses the comments made on version 2. Patch "[v2] x86/iommu: introduce AMD-Vi and Intel VT-d Kconfig options" is not included in this series because it has been already merged, and patch "[v2] x86/iommu: iommu_igfx, iommu_qinval and iommu_snoop are VT-d specific" has been splitted up into two separate patches. Xenia Ragiadakou (8): x86/iommu: amd_iommu_perdev_intremap is AMD-Vi specific x86/iommu: iommu_igfx and iommu_qinval are Intel VT-d specific x86/iommu: snoop control is allowed only by Intel VT-d x86/acpi: separate AMD-Vi and VT-d specific functions x86/iommu: make code addressing CVE-2011-1898 no VT-d specific x86/iommu: call pi_update_irte through an hvm_function callback x86/dpci: move hvm_dpci_isairq_eoi() to generic HVM code x86/iommu: make AMD-Vi and Intel VT-d support configurable xen/arch/x86/hvm/vmx/vmx.c | 41 +++++++++++++++ xen/arch/x86/include/asm/acpi.h | 6 ++- xen/arch/x86/include/asm/hvm/hvm.h | 10 ++++ xen/arch/x86/include/asm/iommu.h | 3 -- xen/drivers/passthrough/Kconfig | 22 +++++++- xen/drivers/passthrough/amd/iommu_init.c | 2 + xen/drivers/passthrough/iommu.c | 15 +++++- xen/drivers/passthrough/vtd/intremap.c | 36 ------------- xen/drivers/passthrough/vtd/iommu.c | 3 -- xen/drivers/passthrough/vtd/x86/Makefile | 1 - xen/drivers/passthrough/vtd/x86/hvm.c | 64 ------------------------ xen/drivers/passthrough/x86/hvm.c | 50 ++++++++++++++++-- xen/drivers/passthrough/x86/iommu.c | 5 ++ xen/include/xen/acpi.h | 7 +++ xen/include/xen/iommu.h | 8 ++- 15 files changed, 156 insertions(+), 117 deletions(-) delete mode 100644 xen/drivers/passthrough/vtd/x86/hvm.c -- 2.37.2
