svm: Implements update_pi_irte hook to setup posted interrupt This patch implements update_pi_irte function hook to allow SVM communicate to IOMMU driver regarding how to set up IRTE for handling posted interrupt. In case AVIC is enabled, during vcpu_load/unload, SVM needs to update IOMMU IRTE with appropriate host physical APIC ID. Also, when vcpu_blocking/unblocking, SVM needs to update the is-running bit in the IOMMU IRTE. Both are achieved via calling amd_iommu_update_ga(). However, if GA mode is not enabled for the pass-through device, IOMMU driver will simply just return when calling amd_iommu_update_ga.
