Title:
Audit IOMMU capabilities and disable if there are some incompatible
IOMMU's in the platform
Status in intel:
New
Status in linux package in Ubuntu:
Incomplete
Bug description:
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 Kernel: TBD
