** Description changed: Description Audit the capabilities and extended capabilities and disable IOMMU if there is incompatibility between them. For e.g. cap.first_level_1G_page support=0, and kernel has enabled 1G pages, we should disable SVM on that IOMMU. Audit code for any other anomalies like this, for e.g. difference in address bits supported, HAW, AGAW etc we should disable IOMMU for the whole system if these differences can lead to improper behavior. - Target Release: 20.04 + Target Release: 20.10 Target Kernel: TBD
