  "message": "intel_iommu: Flush stage-1 cache in iotlb invalidation\n\nAccording to spec, Page-Selective-within-Domain Invalidation (11b):\n\n1. IOTLB entries caching second-stage mappings (PGTT\u003d010b) or pass-through\n(PGTT\u003d100b) mappings associated with the specified domain-id and the\ninput-address range are invalidated.\n2. IOTLB entries caching first-stage (PGTT\u003d001b) or nested (PGTT\u003d011b)\nmapping associated with specified domain-id are invalidated.\n\nSo per spec definition the Page-Selective-within-Domain Invalidation\nneeds to flush first stage and nested cached IOTLB entries as well.\n\nWe don\u0027t support nested yet and pass-through mapping is never cached,\nso what in iotlb cache are only first-stage and second-stage mappings.\n\nAdd a tag pgtt in VTDIOTLBEntry to mark PGTT type of the mapping and\ninvalidate entries based on PGTT type.\n\nSigned-off-by: Zhenzhong Duan \u003czhenzhong.duan@intel.com\u003e\nReviewed-by: Clément Mathieu--Drif\u003cclement.mathieu--drif@eviden.com\u003e\nAcked-by: Jason Wang \u003cjasowang@redhat.com\u003e\nReviewed-by: Yi Liu \u003cyi.l.liu@intel.com\u003e\nMessage-Id: \u003c20241212083757.605022-11-zhenzhong.duan@intel.com\u003e\nReviewed-by: Michael S.
