With VT-d Posted-Interrupts enabled, external interrupts from direct-assigned devices can be delivered to guests without VMM intervention when guest is running in non-root mode. You can find the VT-d Posted-Interrtups Spec. in the following URL: http://www.intel.com/content/www/us/en/intelligent-systems/intel-technology/vt-directed-io-spec.html Feng Wu (13): iommu/vt-d: VT-d Posted-Interrupts feature detection KVM: Initialize VT-d Posted-Interrtups Descriptor KVM: Add KVM_CAP_PI to detect VT-d Posted-Interrtups iommu/vt-d: Adjust 'struct irte' to better suit for VT-d Posted-Interrupts KVM: Update IRTE according to guest interrupt configuration changes KVM: Add some helper functions for Posted-Interrupts x86, irq: Define a global vector for VT-d Posted-Interrupts KVM: Update Posted-Interrupts descriptor during VCPU scheduling KVM: Change NDST field after VCPU scheduling KVM: Add the handler for Wake-up Vector KVM: Suppress posted-interrupt when 'SN' is set iommu/vt-d: No need to migrating irq for VT-d Posted-Interrtups iommu/vt-d: Add a command line parameter for VT-d posted-interrupts arch/x86/include/asm/entry_arch.h | 2 + arch/x86/include/asm/hardirq.h | 1 + arch/x86/include/asm/hw_irq.h | 2 + arch/x86/include/asm/irq_remapping.h | 7 + arch/x86/include/asm/irq_vectors.h | 1 + arch/x86/include/asm/kvm_host.h | 9 ++ arch/x86/kernel/apic/apic.c | 1 + arch/x86/kernel/entry_64.S | 2 + arch/x86/kernel/irq.c | 27 ++++ arch/x86/kernel/irqinit.c | 2 + arch/x86/kvm/vmx.c | 257 +++++++++++++++++++++++++++++++++- arch/x86/kvm/x86.c | 53 ++++++- drivers/iommu/amd_iommu.c | 6 + drivers/iommu/intel_irq_remapping.c | 83 +++++++++-- drivers/iommu/irq_remapping.c | 20 +++ drivers/iommu/irq_remapping.h | 8 + include/linux/dmar.h | 30 ++++- include/linux/intel-iommu.h | 1 + include/linux/kvm_host.h | 25 ++++ include/uapi/linux/kvm.h | 2 + virt/kvm/assigned-dev.c | 141 +++++++++++++++++++ virt/kvm/irq_comm.c | 4 +- virt/kvm/irqchip.c | 11 -- virt/kvm/kvm_main.c | 14 ++ 24 files changed, 667 insertions(+), 42 deletions(-)
