Hi, This series adds page request event reporting and response support to the Intel IOMMU driver. This is necessary when the page requests must be processed by any component other than the vendor IOMMU driver. For example, when a guest page table was bound to a PASID through the iommu_ops->sva_bind_gpasid() api, the page requests should be routed to the guest, and after the page is served, the device should be responded with the result.
Your review comments are very appreciated.
