But nesting enablment with out viommu is alot less useful than I had thought :(
Actually, without viommu, the hwpt cache invalidate alone could still support non-SVA case?
That is what I thought, but doesn't the guest still have to invalidate the CD table entry # 0?
Though we still have the blocker at the msi mapping... It still requires a solution, even for viommu series.
Yes, small steps. The point of this step was to get the nested paging only (without msi, pri, etc, etc)
